Full textAbstract:
The problem examined is an infinite anisotropic layer with a through crack at arbitrary orientation, subjected to uniform in-plane remote loading. The purpose of this study is to gain a better understanding of several theoretical models for predicting the direction of crack propagation and the level of load causing crack extension, and to present a new model for predicting the critical load. The discussed models are particularly examined in detail with regard to the physical parameters affecting the results. Comparison is made with available experimental results. It is shown that the normal stress ratio theory provides good agreement with experimental crack growth direction, independent of physical parameters, and that the newly proposed traction ratio theory predicts well the critical load causing crack extension.M.S.

Full textAbstract:
Sectra Communications is today developing cryptographic products for high assurance environments with rigorous requirements on separation between encrypted and un-encrypted data. This separation has traditionally been achieved through the use of physically distinct hardware components, leading to larger products which require more power and cost more to produce compared to systems where lower assurance is required. An alternative to hardware separation has emerged thanks to a new class of operating systems based on the "separation kernel" concept, which offers verifiable separation between software components running on the same processor comparable to that of physical separation. The purpose of this thesis was to investigate the feasibility in developing a product based on a separation kernel and which possibilities and problems with security evaluation would arise. In the thesis, a literature study was performed covering publications on the separation kernel from a historical and technical perspective, and the development and current status on the subject of software evaluation. Additionally, a software crypto demonstrator was partly implemented in the separation kernel based Green Hills Integrity operating system. The thesis shows that the separation kernel concept has matured significantly and it is indeed feasible to begin using this class of operating systems within a near future. Aside from the obvious advantages with smaller amounts of hardware, it would give greater flexibility in development and potential for more fine-grained division of functions. On the other hand, it puts new demands on developers and there is also a need for additional research about some evaluation aspects, failure resistance and performance.Sectra Communications utvecklar idag kryptoprodukter med högt ställda krav på separation mellan krypterad och okrypterad data. Traditionellt har denna separation gjorts i hårdvara med fysiskt åtskilda komponenter, vilket lett till större produkter, högre energiförbrukning och högre tillverkningskostnader än motsvarande system för lägre säkerhetsnivåer. Ett alternativ till hårdvaruseparation har framkommit tack vare en ny typ av operativsystem baserat på ett koncept kallat "separationskärna", som erbjuder verifierbar separation mellan mjukvarukomponenter på en processor likvärdig med fysisk separation. Syftet med examensarbetet var att undersöka möjligheten att basera en produkt på ett sådant system samt vilka ytterligare möjligheter och problem med säkerhetsevaluering av produkten som uppstår. I examensarbetet utfördes en litteraturstudie av publikationer om separationskärnan ur ett historiskt och tekniskt perspektiv, samt den historiska utvecklingen inom säkerhetsevaluering av mjukvara och dess nuvarande status. Dessutom implementerades delar av ett mjukvarukrypto som en demonstrationsenhet baserad på Integrity från Green Hills Software, vilket är ett realtidsoperativsystem byggt kring en separationskärna. Arbetet visade att separationskärnan som koncept har nått en hög mognadsgrad och att det är rimligt att börja använda denna typ av operativsystem till produkter med mycket högt ställda säkerhetskrav inom en snar framtid. Det skulle förutom uppenbara vinster med minskad mängd hårdvara även ge större flexibilitet vid utvecklingen och möjlighet till exaktare uppdelning av funktioner. Samtidigt ställer det andra krav på utvecklarna och det behövs ytterligare utredning om vissa aspekter av hur evalueringsförfarandet påverkas, systemens feltolerans samt prestanda.

Railway signaling is of paramount importance to ensure traffic management andsafety on the rail network. The main lines are divided into sections called ‘blocks’,which are governed by a fixed signal installation. To prevent trains from colliding,each block allows one train at once. In France (and most European countries),train detection is performed by an electrical device called track circuit that consistsof a transmitter and a receiver installed at the track-side, and connected via therails. In the absence of a train, an electrical signal flows from the transmitter tothe receiver through the rails. As a train enters a track circuit, its axles shuntthe rails, provoking a short circuit (also called ‘shunt’): the signal transmitted tothe receiver drops. The detection of that signal drop results in the detection of atrain. This method rarely fails throughout the network, but there can be criticalcases where it may be inefficient. In this Master’s Thesis, new detection criteriaproposed in previous studies have been tested on signals measured in poor shuntingconditions. Three approaches have been tested: one in the time domain and two inthe frequency domain. The time approach compares the short-term and long-termstatistics of the received signals. The observation of a change in the spectra of thereceived signals around the 3rd order harmonic (3OH) has led to the implementationof two frequency criteria: the estimation of the band power around the 3OH andthe detection of the 3OH peaks. The obtained results show that better detection isachieved when the new criteria and the existing one are combined.Tågsignalsystem är väsentliga för att garantera trafikstyrning och säkerhet i tågnätet.Spåren är indelade i sektioner, s.k. block, som övervakas med fasta signalinstallationer.För att hindra tåg från att krocka, tillåts bara ett tåg i taget per block. IFrankrike (och de flesta andra europeiska länder), detekteras tågen med en elektriskspårkrets som består av en sändare och en mottagare som är installerad bredvidspåret och ansluten till rälsen. När inget tåg finns på spåret, flyter en elektrisk signalfrån sändaren till mottagaren via spåret. När ett tåg anländer, kortsluts kretsenav hjulaxeln och signalen försvinner från mottagaren. Minskningen i signalstyrkaanvänds för att detektera tåget. Denna metod sällan misslyckas i tågnätet, men iovanliga fall kan det uppstå farliga situationer. I detta examensarbete utvärderasnya detektionsmetoder, som har föreslagits i tidigare studier, på signaler som haruppmätts under förhållanden med dålig kontakt mellan hjul och spår. Tre olika metoderhar testats, en i tidsdomänen och två i frekvensdomänen. Tidsdomänsmetodenjämför kortvarig och långvarig statistik för den mottagna signalen. I spektrum förden mottagna signalen, har man observerat en förändring runt den tredje övertonen,samt detektering av frekvenstoppar vid tredje övertonen. De erhållna resultatenvisar på förbättrad detektering när de nya och existerande kriterierna kombineras.

Full textAbstract:
This research studies project success in the context of decision-makers in young, entrepreneurial companies, namely startups. More precisely the companies are European companies that are independent, active and under 10 years of age, and furthermore identified as startups through a framework created from literature derived from Organizational Life Cycle theory and other pluralistic literature about startups. The main concentration is in the concepts related to project success: Project Success Criteria and Critical Success Factors, based on two research questions: 1. “What success criteria are perceived to be most relevant in the project management of startup firms?” 2. “What critical success factors are perceived to be most relevant in project management of startup firms and why?” Previous studies on project management have been mostly conducted in the context of large organizations and typically in a quantitative form. Studies in project management of startups have been scarce, and in project success, nonexistent. Researchers have called upon project literature that concentrates on particular organizational context. In this study, existing theories are studied to find the most suitable framework for success criteria. This study is conducted as a case study, wherein interviews were conducted with startup founders, partners and CEOs, located in Finland, Sweden and Germany. The data collection in the interviews consisted of both semi-structured questions and rating of importance regarding the elements of aforementioned theoretical frameworks of Project Success Criteria and Critical Success Factors, creating a rich set of data, forming holistic cases of the view of project success. The resulting indicate that the most relevant success criteria for startup decision-makers are connected to customer relations, which dictates also the importance of short-term and long-term goals. The economic goals as well the preparation for future were more polarizing. The concentration on customer criteria is not divergent from previous research, but the importance of team criteria is a noticeable difference and a common theme across cases. It is also noticeable in the statements of interviewees that in the startup context the uncertainty regarding products, customers, and economical factors create certain tensions in project success assessment. In Critical Success Factors, there were also clear themes that mirror the aforementioned results. It furthermore became apparent that startups do not have clearly established tools or methods for their project management, which may distinguish them from larger, more established organizations.

Full textAbstract:
Ad hoc network normally has critical connectivity properties before partitioning. The timely recognition is important in order to perform some data or service replication. Several existing centralized or globalized algorithms declare an edge or a node as critical if their removal will separate the network into several components. We introduce several localized definitions of critical nodes and critical links, using topological or positional information. A node is critical if the subgraph of p-neighbours of node (without the node itself) is disconnected. We propose three definitions of critical links, based on verifying common p-hop neighbours, loop length, and critical status of link endpoints, respectively. The experiments with random unit graph model of ad hoc networks show high correspondence of local and global decisions. Existing algorithms for testing k-connectivity are centralized. In this thesis, we introduce localized criteria for testing k-connectivity. In the first proposed local neighbor detection (LND) criterion, each node verifies whether or not itself and each of its p-hop neighbors have at least k neighbors. In the second local critical node detection (LCND) protocol, it also tests if the subgraph of its p-hop neighbours of a given node is k-connected. The third local subgraph connectivity detection (LSCD) protocol is based on communications between neighboring nodes to exchange the local decisions starting from k=1. All nodes declare themselves locally 1-connected. For k=2,3,..., iteratively, local decisions are propagated to p-hop neighbors. If node A is (k-1)-connected, all its p-hop neighbors are (k-1)-connected, and the graph consisting of p-hop neighbors of A (excluding A) is (k-1)-connected, then node A declares its neighborhood as k-connected. The experiments are carried with two ways of uniform generation of connected unit disk graphs. They show low percentage of false 'alarms', ability to locate critical areas in k-disconnected networks, and increased accuracy with increased local knowledge.

Full textAbstract:
BIM (Building Information Modelling) är idag ett exponentiellt ökande område inom byggindustrin, som inte visar några tecken att sakta ner. I takt med att BIM som koncept och process används i större omfattning både internationellt och nationellt, dyker problem dock oundvikligen upp vid dess implementering. De faktorer som orsakar dessa problem har i detta examensarbete givits termen CSF, ett begrepp som hittills ej använts inom svensk byggindustri. CSF står för Critical Success Factors, vilket innefattar det som i svenska arbeten annars till exempel kallats ”kritiska faktorer”, ”hindrande faktorer”, ”bromsande faktorer” etc. Syftet med detta arbete är därmed att utforska både begreppet CSF och dessa faktorer, samt deras betydelse och relevans. Utifrån tidigare studier, främst utländska, identifierades och introducerades termen CSF samt 14 sådana punkter, vilka gavs en utförligare beskrivning. För att ge dessa 14 punkter en lokal anknytning, intervjuades fem personer i svensk byggindustri med olika erfarenheter av BIM. Det framträdde då klara likheter mellan tidigare diskussion kring de identifierade punkterna och intervjuresultaten. De centrala tankar som kontinuerligt återkom under arbetets gång var värdet av gemensam och delad förståelse, samt vikten av att ta vara på redan etablerad kunskap inom byggindustrin. Det finns i branschen en ofta påtalad klyfta mellan olika generationer, vilket enligt detta arbete ses som det tydligaste exemplet både på en bristande förståelse och ett dåligt utnyttjande av tidigare kunskaper. Vid ett ineffektivt möte mellan olika erfarenheter och kunskaper så leder detta till friktion istället för utveckling, med bortslösade resurser och kunskaper som resultat. Ett stort fokus med detta arbete blev därför att betona den mänskliga aspekten av BIM-implementering snarare än de tekniska delarna. Slutligen konstaterar detta examensarbete att de 14 utvalda punkterna samt användandet av deras övergripande term CSF har ett mervärde både för framtida studier och framtidens implementeringar av BIM, vilket därmed även uppfyller rapporten syfte.BIM (Building Information Modeling) is an exponentially growing field within the construction industry, with no signs of slowing down. However, as the process continues to spread on both an international and national scale, issues with implementation inevitably arise due to many different factors, in this work identified as CSF (Critical Success Factors). The purpose of this work is therefore to examine these factors, as well as the term CSF itself, with regards to meaning and relevance. Based on previous studies the term CSF, as well as 14 factors, were established. To correlate these internationally described factors to the Swedish market, five interviews featuring people with experience of BIM in Sweden were conducted, after which similarities and patterns could be recognized. The core concepts continually established throughout the work was the value of mutual and shared understanding, as well as the importance of utilizing previously established knowledge within the construction industry. The report concludes that the identified factors as well as the term CSF are both valid and beneficial for future discussions and implementations of BIM

Full textAbstract:
This study aimed to explore teachers&rsquoconceptions of critical thinking and practices for critical thinking development in Turkish, social studies, science and technology and mathematics courses at seventh grade level. The study was conducted with a phenomenological approach in which 70 teachers from 14 elementary schools in Ankara participated. Data were collected through in-depth interviews with teachers. The findings of the study revealed that there were cognitive skills, dispositions and criteria that teachers perceived to relate to critical thinking. The results also shed light on teachers&rsquo
perceptions on the acquisition of critical thinking, the roles that they assumed in the process of enhancing students&rsquo
critical thinking, teaching approaches they held with regard to the enhancement of students&rsquo
critical thinking, and the conditions that they deemed necessary to develop critical thinking in class. Moreover, teachers&rsquo
planning for the integration of critical thinking into their instruction revealed the limitations of the programs in teaching for critical thinking and the alterations that they made to eliminate these limitations and set the stage for students to think critically. In addition, teachers&rsquo
practices for the incorporation of critical thinking into instruction at seventh grade level illuminated instructional strategies that teachers used, in-class activities that they conducted, and assignments that they gave to students for the purpose of fostering their critical thinking. Furthermore, perceptions on teachers&rsquo
assessment of students&rsquo
critical thinking provided insight into the instruments that teachers used in the assessment of students&rsquo
critical thinking, the kind of critical thinking skills and dispositions that they aimed to assess, their perceptions on criteria by which they judged students&rsquo
critical thinking, and reasons behind any reservations about the assessment of students&rsquo
critical thinking. Besides, teachers&rsquo
perceptions on obstacles to and opportunities for the development of students&rsquo
critical thinking helped to identify the factors that inhibited or fostered their ability to focus on critical thinking skills in their classes. Finally, it should be noted that with regard to all the aforementioned issues, discipline-specific categories, as well as the categories across all four disciplines, emerged.

Full textAbstract:
The entrance space of a hospital has formed an effective period of hospital life since it has reflected the scope and the image of the entire facility. Therefore it has directly influenced by the new formation of healthcare facilities on preserving and growing role of the community health instead of threatening the illnesses. Since entrance space is apart from the other spaces in the facility that has shaped by the restrictive nature of the medical technology, the space most efficiently implement these new objectives more than any space of the entire facility. However, entrance spaces of hospitals in Turkey are still bothered with many insufficiencies and displayed a problematic panorama. Therefore, this thesis has obtained the problems of main entrance space, and
has analyzed it with a consistent form of criteria to gather new solution proposals. In order to serve for this purpose, the present Turkish health care environment has explored and entrance space has been analyzed around new emerging concepts that reflect the changing ideals of the community. To present the problems and solution proposals about this specific place sufficiently, they are also evaluated through design and performance criteria. The essence of coping with the stress created by the environment with healing potential is emphasized. As a result, this thesis is expected to influence further researches, new hospital main entrance space designs as well as the renovation of older ones.

Full textAbstract:
Success is a complex concept, that people have been trying to understand for some time. Extensive research has been conducted in order to improve our understanding, and thus increase our chances for achieving success. However, as projects still continue to fail, the real value of this research seems unclear. This thesis emphasizes the distinction between variables that may cause success (success factors), and variables that are part of success (success criteria). Success is not a 'black and white' concept, in that different viewpoints may produce different evaluations, due to different underlying criteria. Hence, the same IT project may be considered successful from one viewpoint, while a failure from another. In addition, the context affecting IT projects will differ from project to project, both within and between organizations. This thesis suggests that this context can not be limited to a certain set of dimensions. The difference in context produces differences to the appropriate definition of success between projects. Hence, no general ultimate list of success criteria for all projects seems to exist. This thesis therefore makes an effort to investigate whether dynamic selections of success criteria are applicable, through two qualitative case studies. However, both of the dynamic selections investigated came up short in the cases studied. Hence, the appropriate success criteria seems to remain a matter of definition, that needs to be concluded and agreed upon by each respective project team.Some research has attempted to reduce success down to lists of what they refer to as critical success factors. However, as context will differ from project to project, no ultimate list of success factors seem to exist. The lists of critical success factors are in addition unfortunately sometimes presented with an indication of a guaranteed success. One would therefore be tempted to believe that it is relatively easy to achieve success. However, this study demonstrates that the possible value of a mere list of factors seems limited, by investigating how user involvement, one of the most heavily discussed and recognized success factors, is dealt with by project teams in practice. The thesis concludes that the challenges related to user involvement goes beyond the question of whether to involve users or not, and correspondingly that listing user involvement as a critical success factor in itself has little value.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOREste trabalho trata da gestão de múltiplos projetos mediante a metodologia da Cadeia Crítica e Gestão de Buffers (Critical Chain and Buffer Management CC/BM). Concentra-se na análise e entendimento dos efeitos que as abordagens mais usuais para dimensionamento dos buffers de capacidade (Capacity Buffers BC) e definição dos critérios de priorização de atividades têm sobre os objetivos da empresa e dos próprios projetos. O estudo baseia-se num problema-exemplo apresentado por Pritsker B. et al. (1969.). Para facilitar a análise, esse exemplo se caracteriza por uma estrutura simples, mas que apresenta interdependências relevantes para o estudo dos conflitos de compartilhamento de recursos entre projetos. Analisam-se as abordagens de todos juntos, projetos sucessivos e do recurso gargalo, propostas por Newbold (1998) para planejamento conjunto de projetos simultâneos. Tais abordagens são implementadas através das ferramentas de programação de projetos Prochain & Pipeline. A partir dos programas (schedules) resultantes, analisam-se as características e deficiências de cada abordagem. Ademais, tais resultados permitem identificar certas condições e efeitos conflitantes no dimensionamento dos BC e no critério de priorização de atividades utilizado nas implementações típicas da metodologia. Tais observações criaram a necessidade de complementar a análise mediante a simulação probabilística da etapa de execução dos projetos. A pesquisa explica a diferença entre os efeitos dos critérios de priorização dinâmica e estática, esclarece a interação entre os buffers de capacidade e buffers de projeto. Ela ainda analisa os efeitos de dimensionar os BCs, para todos os projetos, como uma mesma porcentagem da carga do recurso e ilustra os trade-offs entre estabilidade do sistema e o makespan dos projetos.
This research addresses the management of multiple simultaneous projects through the application of the Critical Chain and Buffers Management (CC/BM) methodology. The focus is on the analysis and interpretation of the effects that the more usual approaches for Capacity Buffers (CB) sizing and criteria to prioritize activities have on the companys and on the projects own objectives. The study is based on the problem-example presented by Pritsker B. et al. (1969.) For simplifying the analysis, this example is characterized by a simple structure that, nevertheless, presents interdependences significant for the study of conflicts created by sharing resources between simultaneous projects. The approaches for simultaneous projects management, presented by Newbold (1998) are analyzed, namely: the all together, the successive projects and the strategic resource. Their implementations are made using the Prochain & Pipeline multi-project management tools. From the resulting schedules, the characteristics and deficiencies of each approach are analyzed. Furthermore, these results allow the identification of certain conditions and conflicting effects in the BC sizing and in the criteria used to prioritize activities in the typical methodology implementations. Such observations led to the necessity of complementing the analysis with the aid of probabilistic simulation of the projects execution stage. The research explains the differences between the effects of dynamic and static prioritization, elucidates the interaction between the capacity and the project buffers. It also examines the effects of using the same percentage of the resource load for sizing the BCs for all the projects, and illustrates the trade-offs between the system stability and the projects makespan.

Full textAbstract:
Most of the older reinforced concrete (RC) buildings have columns that are deficient
when the current code requirements are considered. Therefore, performance of the columns
determines the performance of the structure under the effects of earthquake induced lateral
loads. It is recognized that no provision is proposed in TEC2007 to estimate the failure type
called flexure-shear. Behavior of columns having probability of failing in flexure-shear
failure mode is mostly underestimated by TEC2007 procedures. In addition, failure type
classification of columns performed according to the linear and nonlinear procedures of
TEC2007 needs to be examined with respect to the test results to cover all failure types
including flexure-shear failure in order to lead the engineers develop economical and
realistic retrofit solutions.
In this study, different methods are explored to obtain reliable estimates for the
performance of code deficient shear critical RC columns. Special considerations are given to
Axial-Shear-Flexure interaction (ASFI) approach due to its mechanical background.
After examination of different approaches, ASFI method with proposed
modifications was selected as the most reliable model and lateral load-displacement analyses
were performed on a database of shear critical columns. Findings were compared with the
estimations of the nonlinear procedure given in Turkish Earthquake Code (TEC2007) for
database columns. In addition, drift capacity equations and simplified safe drift capacity
equations are proposed in light of statistical studies on the selected column specimens.
In the last part of the study, performance evaluation of columns according to
nonlinear procedures of FEMA 356, TEC2007, ASCE/SEI 41 update supplement, and
EUROCODE 8 were conducted.

Full textAbstract:
The Cherokee Nation, a Federally-recognized Tribal government in Northeastern Oklahoma lacks Tribal water quality standards for numerical nutrient standards based on baseline conditions in the Cherokee Nation. Lotic waters are of special significance in Cherokee Nation culture and ceremonies. Three water quality standard priorities within the Tribe include defining Culturally Significant Waters as a designated use, identifying Culturally Significant Waterbodies and determining applicable numerical nutrient standards. Culturally Significant Water as a designated use was defined based on community surveys. Twelve rivers and streams were identified as a portion of the Culturally Significant Waters of the Cherokee Nation based on a tribal community survey using a Use Attainability Analysis. To address excess nutrients in the Cherokee Nation, a total phosphorus numerical nutrient criterion was determined using data for Culturally Significant Water bodies, literature guidance and the US Environmental Protection Agency recommended nutrient criteria process for the respective Aggregate Nutrient Ecoregion. The Oklahoma Scenic Rivers criterion of 0.037 mg/L total phosphorus for a 90-day geometric mean was evaluated and determined not to be protective of Cherokee Nation’s Culturally Significant Waters. A total phosphorus criterion of 0.016 mg/L was recommended to protect Cherokee Nation Culturally Significant Waters from benthic algae greater than 100 mg/m2 Chlorophyll a.

Full textAbstract:
Due to the current high levels of urbanisation and the lingering effects of Apartheid, South African municipalities have experienced difficulties in planning for sustainability and more specifically sustainable community development. Sustainable community development is needed in order to achieve more integrated and sustainable towns and cities with an improved urban environment and a higher quality of life. Due to this sustainable community development is of particular relevance to South Africa. Although policies and legislation exist at international, national and local level, there is a lack of suitable planning instruments to guide sustainable community development.
Tlokwe Local Municipality is researched as study area to test and develop planning instruments for sustainable community development. An assessment matrix of sustainability indicators is linked to Multi-criteria analysis (MCA) and applied to identify the themes and sub-themes applicable to sustainability in which intervention is required to improve the sustainability rating of the municipality. A Goal Assessment Matrix (GAM) approach is used to score and prioritise municipal projects, plans and strategies according to sustainable community development fundamentals. The top scoring projects are indicative of the achievement of sustainable community development goals and objectives. The result of the sustainability assessment is that the Tlokwe Local Municipality is considered to be relatively sustainable, performing overall better than the three spheres of government against which it was measured. Subsequent to the GAM assessment a lack of alignment between the sectoral plans was identified as well as the duplication of projects. The projects, plans and strategies of the municipality are found to not have been formulated with sustainable community development framework as a guiding goal.
It is recommended that municipalities use the assessment matrix methods to determine its level of sustainability when developing respective sectoral plans (SDFs, ITPs, EMFs and IDPs). Areas in which there is a lack of sustainability are highlighted and can consequently be addressed through intervention strategies. Prioritising municipal projects, plans and strategies through the use of GAM identifies crucial projects that need special attention to ensure their successful implementation as this will largely aid sustainable community development. Both the assessment matrix method and the GAM approach are valuable planning instruments with which to achieve sustainable community development.Thesis (MArt et Scien (Urban and Regional Planning))--North-West University, Potchefstroom Campus, 2013

Within the vast work that has been done on assisted suicide, this thesis examines how assisted suicide may be legalised in England and Wales if Parliament decides that is necessary in the future. The thesis takes as starting point the three eligibility criteria proposed by the Commission on Assisted Dying, a privately-funded Commission established in 2012 to review the status of the current law in England and Wales. The thesis focuses on the practical side of the assisted suicide debate, and hints that studying how legalisation could take place in the future may hinge on whether it can ever be realised in practice. In particular, the thesis suggests that if Parliament decides to legalise assisted suicide in England and Wales, it should adopt a medico-legal framework that will respect both the right to life (Article 2) and the right to self-determination (Article 8) and the state obligations arising from these, and attempt to strike a balance. Parliament will then respect the rights of those who choose death over life, and safeguard the lives of those who do not want to die but may be unduly influenced into assisted death. To achieve this balance, the criterion relating to the physical or mental condition of the individual (terminal illness or unbearable suffering) should be abandoned, and a robust approach to safeguards adopted. Individuals should be able to request an assisted death if they have mental capacity, if they make a voluntary and informed decision, and if the Family Division of the High Court approves the assisted death. This is a new proposal that should be considered as an option if, and when Parliament decides that the time is ripe for legalisation. The right to control the manner and timing of death is ‘the last human right’ to which individuals should have access.

Full textAbstract:
Mergers and acquisitions (M&A) in the corporate world are achieving increasing importance and attention especially in the advent of intense globalization. This is evident from the magnitude and growth of deal values and resultant ‘mega-mergers’ transacted in recent times. As expert advisory are sought in M&A activities to facilitate the undertaking and maximise the value of the transaction, advisory firms begin to play a more significant and at the same time lucrative role in M&A activities, to the extent of determining the outcome of such projects. Being an area of limited research, it is thus valuable to investigate what M&A advisory firms view as critical success factors to the projects they undertake. Consequently, the research question of “What are the critical success factors for merger & acquisition projects in the view of merger & acquisition advisory firms” has been raised. A list of ten critical success factors for M&A projects is firstly identified from an extensive literature review. These factors are (1) Complete and Clear objectives, goals and scope of the project, (2) Client consultation and acceptance, (3) Project manager’s competence and commitment, (4) Project team member’s competence and commitment, (5) Communication and information sharing and exchange, (6) Project plan development, (7) M&A advisory firm’s resource planning, (8) Time management and tight secrecy, (9) Price evaluation and financing scheme, and (10) Risk management.
In an attempt to explore the importance of each factor in the practical context, data have been collected through three research methods. Primarily, the authors conduct a semi-structured interview with six interviewees currently working in three organizations which provide professional services related to M&A projects. Meanwhile, a self-completion questionnaire method is employed, following which a sample of 325 M&A advisory firms based in the U.S. is selected to participate in an online survey. In addition, the authors follow a case study approach based on the three organizations of the six interviewees in order to establish comprehensive knowledge about issues relating to M&A projects.
In response to the research question, the findings strongly indicate that seven out of ten factors in the original list have a positive impact, being the factors listed above as (1), (2), (3), (4), (5), (8), and (9). On the other hand, it revealed the lesser importance of the other three. In addition, three new factors have been discovered from analyzing the data collected, being (i) Having a number of key potential buyers with suitable profile (ii) Right, correct and complete information and data in the data room, and (iii) The quality of the selling company. While as another outcome of this research, further practical insights have been provided regarding the role of M&A advisory firms, the M&A process, common issues faced by M&A projects and the success criteria for M&A projects.
The findings from this research contribute valuable new knowledge to both researchers and practitioners in both project management and M&A fields, while facilitating the achievement of successful M&A projects.

Ce travail de thèse doctorale traite l'analyse de la vulnérabilité des systèmes critiques pour la sécurité (par exemple, les centrales nucléaires) dans un cadre qui combine les disciplines de l'analyse des risques et de la prise de décision de multi-critères.La contribution scientifique suit quatre directions: (i) un modèle hiérarchique et quantitative est développé pour caractériser la susceptibilité des systèmes critiques pour la sécurité à plusieurs types de danger, en ayant la vue de `tous risques' sur le problème actuellement émergeant dans le domaine de l'analyse des risques; (ii) l'évaluation quantitative de la vulnérabilité est abordé par un cadre de classification empirique: à cette fin, un modèle, en se fondant sur la Majority Rule Sorting (MR-Sort) Méthode, généralement utilisés dans le domaine de la prise de décision, est construit sur la base d'un ensemble de données (en taille limitée) représentant (a priori connu) des exemples de classification de vulnérabilité; (iii) trois approches différentes (à savoir, une model-retrieval-based méthode, la méthode Bootstrap et la technique de validation croisée leave-one-out) sont élaborées et appliquées pour fournir une évaluation quantitative de la performance du modèle de classification (en termes de précision et de confiance dans les classifications), ce qui représente l'incertitude introduite dans l'analyse par la construction empirique du modèle de la vulnérabilité; (iv) basé sur des modèles développés, un problème de classification inverse est résolu à identifier un ensemble de mesures de protection qui réduisent efficacement le niveau de vulnérabilité du système critique à l’étude. Deux approches sont développées dans cet objectif: le premier est basé sur un nouvel indicateur de sensibilité, ce dernier sur l'optimisation.Les applications sur des études de cas fictifs et réels dans le domaine des risques de centrales nucléaires démontrent l'efficacité de la méthode proposéeThis Ph. D. work addresses the vulnerability analysis of safety-critical systems (e.g., nuclear power plants) within a framework that combines the disciplines of risk analysis and multi-criteria decision-making. The scientific contribution follows four directions: (i) a quantitative hierarchical model is developed to characterize the susceptibility of safety-critical systems to multiple types of hazard, within the needed `all-hazard' view of the problem currently emerging in the risk analysis field; (ii) the quantitative assessment of vulnerability is tackled by an empirical classification framework: to this aim, a model, relying on the Majority Rule Sorting (MR-Sort) Method, typically used in the decision analysis field, is built on the basis of a (limited-size) set of data representing (a priori-known) vulnerability classification examples; (iii) three different approaches (namely, a model-retrieval-based method, the Bootstrap method and the leave-one-out cross-validation technique) are developed and applied to provide a quantitative assessment of the performance of the classification model (in terms of accuracy and confidence in the assignments), accounting for the uncertainty introduced into the analysis by the empirical construction of the vulnerability model; (iv) on the basis of the models developed, an inverse classification problem is solved to identify a set of protective actions which effectively reduce the level of vulnerability of the critical system under consideration. Two approaches are developed to this aim: the former is based on a novel sensitivity indicator, the latter on optimization.Applications on fictitious and real case studies in the nuclear power plant risk field demonstrate the effectiveness of the proposed methodology

Full textAbstract:
Fatigue, or failure of material due to repeated cyclic loading, is one of the most common causes of mechanical failures. The risk of fatigue in a load carrying component is often lowered by adding material, thereby reducing stresses. This increases the component weight, reducing the performance of the component and increasing its manufacturing cost. There is thus a need to design components to be as light as possible, while keeping the risk of fatigue at a low enough level, i.e. there is a need for optimization of the component subject to fatigue constraints. This thesis deals with design against fatigue using topology optimization, which is a form of structural optimization where an optimal design is sought by using mathematical programming to decide which parts of a design domain should be filled with material, and which should not. To predict fatigue, accurate representation of the geometry and accurate stress computation are of utmost importance. In this thesis, methods for imposing constraints such as minimum inner radii and minimum member sizes in the form of four new density filters are proposed. The filters are able to generate a very sharp representation of the structural boundary. A method for improving the accuracy of stress results at the structural boundary is also proposed, based on extrapolation of results from the interior of the structure. The method gives more accurate stresses, which affects the resulting structures when solving optimization problems. A formulation for fatigue constraints in topology optimization is proposed, based on the weakest link integral. The formulation avoids the problem of choosing between accurate but costly local constraints, and efficient but approximate aggregated constraints, and gives a theoretical motivation for using expressions similar to the p-norm of stresses. For verifying calculations of the fatigue probability of an optimized structure, critical plane criteria are commonly used. A new method for evaluating such criteria using optimization methods is proposed, and is proved to give results within a user given error tolerance. It is shown that compared to existing brute force methods, the proposed method evaluates significantly fewer planes in the search of the critical one.QC 20150504

Full textAbstract:
Enterprises of any size need to face different challenges which might be specific to their environment or their structure. Therefore, to overcome these barriers each company owner needs to take into consideration suitable ways through which the available and potential resources can be best use in dealing with the business context. Issues like, market breakthrough and acceptance, competition, economic environment, can prove to be critical for a small business which bases its activities on innovation type of services and products. By studding the specific context of small businesses with an entrepreneurial and innovative character, we try to address in this thesis one of the particular ways through which these type of companies can face challenges within their environment: by involving different categories of external support in their projects and business activities. While the need for capital, information and co-operation is growing along with the small business development, we also have chosen to focus our attention on three types of support infrastructures: finance, information and network. Then, each of these support aspects is analysed in connection with project critical success factors in order to establish a certain relevance that external assistance can have on project success. The case studies are based on five small companies within a Swedish incubator in the region of Västerbotten county. As for our study we consider governmental agencies, universities and Science Parks, as three representative support agents, we decided to take closely analyse one of them, and so we looked at the policies and environment of the incubator which hosts the five small companies. And so, Uminova Innovation and its incubator, which are part of Uminova Science Park, could be considered as the overall case study framework. Then, the outcomes of this thesis highlight the perceived influence of the three support infrastructures: finance, information and networks on the business projects, activities and processes. Although the particular business characteristics have their own impact when it comes to the types of support each studied company choose to approach, a general link has been noticed between a certain type of business activities or plans and the involved support. As this study brings up particular matters which engage both small business and the business support agents, we believe that the outcomes of the analysis and the broad theoretical framework would be a suitable reference for practitioners of support policies as well as for small business owners. Therefore, the actions and policies of these actors can be further developed by taking in consideration the critical success factors which have a direct implication in enhancing a particular support that further can contribute to project success.

Full textAbstract:
Construction Project Procurement Methods (PMs) define the roles, relationships and responsibilities of project team members and the sequence of the activities required to construct or provide a facility. A number of different PMs have evolved over the years, but each is characterised by a different set of features upon which the criteria for selecting the most appropriate method to procure a given project must be based, if successful project performance (PP) is to be ensured. The use of procurement method selection criteria (PMSC) to inform clients’ decision on suitable PMs to adopt remains a recommended good practice in the construction industry. However, project clients in the Libya Construction Industry (LCI), continue to face great challenges when it comes to selecting the most appropriate PM for its projects. The general practice in this industry is largely dominated by a culture of clients’ reliance on their familiarity and experience with a particular method to inform their PM choice, with no consideration of the plethora of other PMs and use of rational approaches to aid in this decision-making. This procurement issue has long been recognised as a major contributory factor to the frequent time and cost overruns often experienced by projects in the LCI. Although the selection of an appropriate PM to procure any given project is known to result in success PP and (and vice versa), very little is known about the nature of this relationship from literature. Having persistently suffered a great deal of project failures over the years, the LCI stands to benefit from detailed knowledge and understanding of how exactly PM choice do actually influence PP. Stimulated by the dearth of this information, this thesis reports on a research investigation into this relationship with the aim of developing a model to explain the criteria functions in contributing to PP and their implications to PM selection practice in Libya. The methodological approach adopted for this research was the mixed method, i.e., using a combination of both quantitative and qualitative approaches. Following a critical review of the extant relevant literature, a number of relevant hypotheses were first formulated, together with a conceptual framework, to establish the theoretical basis underpinning this research, namely the relationship between the selection of PMs (based on PMSC) and PP. The primary data collection stage involved an initial field questionnaire survey aimed at identifying and confirming the key areas of the research inquiry that needs focusing on. This was followed by a semi-structured questionnaire and interview surveys. With the aid of SPSS and Excel, the collected data were analysed, followed by the development of a mathematical model (based on regression) that demonstrate the influence of PMSC on PP. Finally, the model was validated by expert interviews to test for its validity and reliability. The key findings of the research include the identification of DBB and DB selection criteria that contributes to PP. The distinct contribution to knowledge arising from this research includes the development of a regression model to demonstrate this relationship between PMSC and PP. The benefit of these outputs lies not only in the ability of LCI’s clients to make PM selection decisions much faster by virtue of the need for them to only focus on the criteria with significant influence on PP, they are also able to work out, in quantitative terms, the PP outcomes to be expected for each of the method being considered. This latter information would enable clients to compare the PP outcome values expected from their decisions to select DBB and DB, and then be able to conclude which of these two options represents a better procurement strategy for any given project at hand.

Thesis (MMed)--Stellenbosch University, 2014.ENGLISH ABSTRACT: BACKGROUND Post anesthesia discharge criteria scoring systems have been used successfully to aid discharge from the post anesthetic care unit (PACU) for over 40 years. They do not replace, but rather act in conjunction with good clinical judgment, and provide concise, standardized documentation of a patient’s readiness for discharge. 1,2,3,4,5 In order to improve patient safety, provide clear documentation and to aid future audit, a discharge criteria scoring system was developed for use in our PACU (Addendum A). It is a modification of the Aldrete Scoring System and the modified Post Anesthetic Discharge Scoring System (PADSS) proposed by Chung.1 There is a steadily increasing patient burden on the existing medical infrastructure in South Africa. Tygerberg Academic Hospital is no exception, and because of the high demand on our theatre services, optimal efficiency is essential. We speculated that our discharge criteria scoring system might increase the efficiency of our PACU when compared to the traditional time based system. The more healthy patients, undergoing minor procedures, could potentially spend less time in PACU, allowing the nurses to focus on problem cases. Increasing the speed of transit might also help prevent delays in theatre due to lack of bed space in PACU. Our primary endpoint was to compare the duration of time spent by patients in the PACU at Tygerberg Academic Hospital, from the moment they are admitted, to the time they are discharged to the ward, before and after the introduction of a discharge criteria scoring system. While planning the audit, one of the factors that staff identified as contributing to delayed discharge from PACU, was the time it took for the wards to collect their patients. A secondary objective, therefore, was to assess the amount of time that elapsed between calling the ward to collect the patient, and the patient leaving PACU. METHODS AND MATERIALS Prior to commencing the audit, approval was obtained from the Human Research Ethics Committee of the Faculty of Health Sciences of the University of Stellenbosch and Tygerberg Academic Hospital. The Audit, its purpose and possible benefits, was discussed with representatives of the nurses working in PACU, and written consent was obtained from those who would be involved in the data collection (Addendum B). Audit forms (Addendum C), collection boxes, and posters reminding staff to participate in the audit were prepared. Our first audit was performed over approximately a week in August 2012. During this period, the traditional time-based discharge system was still in operation. Data was captured from 327 patients. Audit forms were placed in a collection box, which was cleared daily by the primary investigator. The discharge criteria scoring system was introduced to the PACU staff in January 2013. The nurses were trained in its use, and a one month period was allowed for all involved to become accustomed to the new system. A second audit was performed in February 2013, again over a week, during which we gathered data from 313 patients. RESULTS The median value of the time spent by patients in the PACU decreased from 1 hour 25 minutes, to 1 hour 15 minutes, after introduction of the discharge criteria scoring system. This was statistically significant (p-value = 0.003). The median time between calling the ward to collect a patient, and the patient leaving recovery, was 15 minutes. CONCLUSION The main finding of the study was that the introduction of a discharge criteria scoring system decreased the median duration of time spent by patients in the post anesthetic care unit at Tygerberg Academic Hospital.
AFRIKAANSE OPSOMMING: AGTERGROND Puntestelsels as ontslag kriteria na narkose, word vir die afgelope 40 jaar suksesvol gebruik as maatstaf om pasiënte uit die herstelkamer te ontslaan. Hierdie kriteria vervang nie goeie kliniese oordeel nie, maar is ’n addisionele hulpmiddel om te bepaal of die pasiënt gereed is vir ontslag en om noukeurige, gestandardiseerde dokumentasie te verseker. 1,2,3,4,5 'n Nuwe puntestelsel vir ontslag is vir die herstelkamer van Tygerberg Akademiese Hospitaal ontwikkel om pasiëntesorg en dokumentasie te verbeter, asook om ouditering in die toekoms te vergemaklik (Addendum A). Hiervoor is die Aldrete Scoring System en die gemodifiseerde PADSS, voorgestel deur Chung, aangepas. 1 Die bestaande mediese infrastruktuur in Suid-Afrika beleef tans ‘n geleidelike toename in die getal pasiënte. Tygerberg Akademiese Hospitaal is geen uitsondering nie en as gevolg van die hoë aanvraag na ons teaterdienste, is uiterste doeltreffendheid noodsaaklik. Ons vermoede was dat hierdie aangepaste puntestelsel doeltreffendheid in die herstelkamer sou verbeter in vergelyking met die meer tradisionele tyd-gebaseerde sisteem. Gesonde pasiënte wat kleiner prosedures ondergaan, sal waarskynlik na ’n korter periode ontslaan kan word wat die verpleegpersoneel in staat sal stel om meer aandag aan probleem gevalle te gee. Bespoediging van die pasiëntvloei behoort onnodige vertragings van teatergevalle weens 'n tekort aan beddens in die herstelkamer, te beperk. Die primêre doel van die studie was om te bepaal of die gebruik van die aangepaste puntestelsel as ontslag kriteria in Tygerberg Akademiese Hospitaal, die tydperk wat die pasiënt in die herstelkamer deurbring, verkort. Die herstelkamer verpleegsters het beweer dat die saal personeel ‘n lang tyd gevat het om hulle pasiente in herstelkamer te kom haal. Vervolgens is 'n sekondêre doelwit ingesluit om die tydperk te bepaal vandat die saalpersoneel in kennis gestel word, totdat die pasiënt die herstelkamer verlaat. METODE Goedkeuring is verkry van die Menslike Navorsing en Etiese Komitee van die Gesondheidswetenskap Fakulteit van die Universiteit van Stellenbosch en Tygerberg Akademiese Hospitaal voor die aanvang van die studie. Die studie, asook die doel en moontlike voordele daarvan is vooraf bepsreek met verteenwoordigers van die herstelkamer verpleegpersoneel en skriftelike toestemming is verkry van al die deelnemers wat betrokke sou wees by die data versameling (Addendum B). Oudit vorms (Addendum C), versamelhouers en inligtingsplakkate vir die betrokke personeel is voorberei. Die aanvanklike oudit is in Augustus 2012 oor 'n periode van ongeveer een week uitgevoer. Tydens hierdie oudit is die tradisionele tydgebaseerde sisteem gebruik. Inligting van 327 pasiёnte is versamel. Die oudit vorms is in die versamelbokse geplaas en is daagliks deur die primêre navorser verwyder. Die aangepaste puntestelsel as ontslag kriteria, is in Januarie 2013 in die herstelkamer geïmplementeer. Die verpleegpersoneel het opleiding ontvang waarna die aangepaste puntestelsel vir een maand gebruik is om te verseker dat die personeel vertroud is daarmee. In Februarie 2013, is ‘n tweede oudit oor ‘n tydperk van een week uitgevoer, waartydens inligting van 313 pasiёnte versamel is. RESULTATE Na die implementering van die aangepaste puntestelsel as ontslag kriteria, het die mediane tyd wat pasiënte in die herstelkamer deurbring afgeneem van 1 uur en 25 minute tot 1 uur en 15 minute. Hierdie afname is statities betekenisvol (p-waarde = 0.003) Die mediane tyd vandat die saal in kennis gestel is totdat die pasiënt die herstelkamer verlaat, was 15 minute. GEVOLGTREKKING Die hoof bevinding van die studie is dat die mediane tydperk wat die pasiënte in die herstelkamer deurbring verminder is deur die implementering van die aangepaste puntestelsel as ontslag kriteria in Tygerberg Akademiese Hospitaal.

Full textAbstract:
Conservatoires all over the world are re-examining their educational roles and practices in a changing cultural and economic context, including re-evaluating their function as sites of relevant learning. This dissertation by publication contributes to this re-examination by investigating understandings of assessment, evaluative reflection, the relationship between know-how and knowledge, autonomous learning, community of practice and the student experience of these pedagogies in one Queensland conservatorium.
The study is presented in the form of a synopsis and five publications, with additional data that will form the basis of further post-doctoral publication. It is focused on non-traditional pedagogical processes operating within a bachelor of popular music program, processes that have been intuited by the academic teacher who is also the author of this dissertation. What these processes have in common is the philosophical rejection of teacher-led pedagogy and an insistence upon, and scaffolding of, self-directed student action and reflection. The aim of the dissertation, in keeping with the rationale for a professional doctorate, is to subject this approach to systematic theoretical and empirical scrutiny, and thereby to further refine and strengthen the practices in terms of their capacity to engage young people in self-directed approaches to quality music making.
John Biggs's presage/process/product learning model (1999) provides a structure for this systematic evaluation of the pedagogical work. The study understands the learning characteristics that students bring to the program, combined with the structures and pedagogical approaches in place in the program, to be the key presage elements; the learning activities (including assessment as learning) that occur within the program are the key process elements; the key products are the learning outcomes for the students and the ongoing development of the program and pedagogical approaches informed by reflection on empirical data including data collected as part of this research.
The study demonstrates the significance of recognising and valuing presage and process elements that enable students to perform from the basis of their intuitive know how while being recorded, and then apply their knowledge-based critical reflection skills to an appraisal of their own work and the work of their peers while hearing the recording played back. While not displacing the teacher as mentor and critical friend, this moves responsibility for learning to the student as a self-monitoring, strategic decision-maker about the nature and quality of their learning products. The program requirement that students write meaningfully about the process appears to encourage the embracing of both conscious and unconscious ways of knowing and doing.
As a documentation of this type of teaching, the study presents an argument for a broader incorporation of student-led pedagogy into higher education in general and
conservatoria in particular. It concludes that aspects of education that enhance students' abilities to learn, including self- and peer assessment, self-directed learning, reflective practice, and both independent and collaborative work that incorporates program-wide learning, are likely to enhance integrated creative practice. This project has made it possible to disseminate a scholarly engagement with such processes through publication in academic and professional contexts.

In order to be certified by the FAA, airborne software must comply with the D0-178B standard. For the unit testing of safety-critical software, this standard requires the testing process to meet a strong source code structure coverage criterion, referred to as Modified Condition/Decision Coverage criterion. This part of the standard is controversial in the aviation community, in particular because the coverage criterion is apparently not related to the safety of the software. In this thesis, we follow the letter of the D0-1788 standard to perform the unit testing of the Attitude Control Sy stem of the HETE-2 satellite. This allowed us to gain some insights on the D0- 1788 testing procedure, and to prove that in the case of the considered software, this method was well adapted.

O objeto de estudo deste trabalho são os critérios de avaliação do desempenho de gerenciamento de projetos, ou em outras palavras, aqueles critérios que podem ser utilizados pelos stakeholders para avaliar se o projeto está sendo, ou foi, bem gerenciado. O objetivo é contribuir para a pesquisa e melhoria do desempenho de gerenciamento de projetos. A primeira fase da pesquisa consistiu de uma revisão na literatura para mapeamento de critérios identificados por outros autores. Uma relação com 20 critérios foi utilizada no questionário aplicado nos estudos de casos para averiguar se tais critérios são utilizados pelas empresas estudadas, e se a seleção e a atribuição de importância dos critérios são influenciadas pelo papel desempenhado pelo entrevistado no gerenciamento dos projetos (gerente, membro de equipe e patrocinador, mais especificamente), pelas características dos projetos ou pela maturidade da empresa em gerenciamento de projetos. Os estudos de caso foram conduzidos em duas grandes empresas multinacionais com alta maturidade e em uma empresa brasileira de médio porte com baixa maturidade. Concluiu-se que, nas empresas estudadas, a seleção dos critérios está altamente associada à natureza e aos objetivos do projeto, não sendo perceptível a influência do papel desempenhado pelo entrevistado. Além disso, nas três empresas a questão da avaliação do desempenho do gerenciamento de projetos foi considerada muito importante tanto para o sucesso dos projetos como para o sucesso da própria organização, fato explicado pela forte contribuição dos projetos para os resultados das empresas e pela interpretação de que projetos bem gerenciados têm maior chance de satisfazer às necessidades e expectativas dos clientes e, desta forma, aumentam a capacidade da empresa de realizar novos negócios com o mesmo cliente e de se posicionar no mercado para realizar negócios com novos clientes. Concluiu-se, também, que a empresa com baixa maturidade apresenta uma tendência a preferir critérios financeiros para avaliação do gerenciamento de seus projetos, enquanto as empresas com alta maturidade preferem um conjunto de critérios multidimensionais.The object of study of this research is the criteria for project management performance evaluation, in other words, those criteria used by the key stakeholders to assess whether or not a project is being or has been well managed. The objective is to contribute to the research and improvement of the project management performance. The first phase of the research consisted by the review of the literature for mapping criteria identified by other authors. A list of 20 criteria has been created and utilized for the preparation of the questionnaire applied to the case studies to verify if those criteria are used by the studied companies and if the selection and importance given are influenced by the role played in the project management by the interviewee (manager, team member and sponsor, more specifically), by the projects characteristics or by the maturity in project management of the company. The case studies were conducted in two large multinationals companies with high-maturity in project management and in a medium size Brazilian company with low maturity in project management. It was concluded that in the companies studied the selection of criteria is highly associated with the nature and objectives of the project and not influenced by the role played by the interviewee. Moreover, the three companies considered the issue of project management performance assessment very important for the success of the projects as well as the companys, fact explained by the strong contribution that projects bring to the results of the companies and by the interpretation that well managed projects are more likely to meet the customers needs and expectations, increasing the company\'s ability to conduct new business with existing clients and to position itself in the market to do business with new clients. Another conclusion is that the low maturity company is more likely to prefer financials criteria to the project management performance assess; on other hand the high maturity companies are more likely to adopt a multidimensional set of criteria.

Nyttjandet av stridstekniska obemannade luftfarkostsystem har ökat kraftigt och har observerats i både Syrien och Ukraina. I den ryska armén har de sett framgångsrik användning i samverkan med befintliga artillerisystem. Syftet med detta självständiga arbete är att analysera och förstå de effekter som tekniken har på militära operationer. I detta arbete används det militärtekniska konceptet ’militär nytta’ Andersson m.fl. (2015) i kombination med Johnsonkriteriet som används för att beräkna räckvidden på infraröda sensorer. Tillsammans med användningen av systemanalys och scenariobaserade metoder, har stridstekniska obemannade luftfarkostsystem och tekniska system som är motverkande mot obemannade luftfarkoster värderats med konceptet militär nytta. Slutsatserna från detta arbete visar att stridstekniska obemannade luftfarkostsystem har en god militär nytta då de används mot en motoriserad skyttebataljon (militär aktör), i förberedelsefasen av en fördröjningsstrid (kontext). Vid värderingen av de två tekniska systemalternativen som motverkar obemannade luftfarkoster; eldvapensystem och robotsystem, har bärbara luftvärnsrobotsystem bedömts ha en bättre militär nytta än automatkanonsystem på grund av dess möjliga användning i avsuttna operationer.This independent project studies Small Unmanned Aerial Vehicles and potential Counter Unmanned Aerial Systems. The usage of Small Unmanned Aerial Systems has grown rapidly and has seen use in warfare in both Syria and Ukraine. In the Russian armed forces, they have seen successful use when used in combination with legacy artillery systems. The purpose of this independent project is to analyse and understand the effects that technology has on military operations. In this project, a military-technology concept called ‘military utility’ Andersson et al. (2015) is used in combination with the Johnson criteria which is used to calculate infrared sensor range. Together with the use of systems analysis and scenario-based methods, Small Unmanned Aerial Vehicles and two identified Counter Unmanned Aerial System alternatives have been assessed with the military utility concept. The conclusions of this independent project show that Small Unmanned Aerial Vehicles have a good degree of military utility when used against a motorized infantry battalion (military actor), in the preparatory phase of a delay operation (context). When assessing the two Counter Unmanned Aerial System alternatives; gun-based systems and missile air defence systems, man-portable air-defence systems have, because of their possible use in dismounted operations, been considered to have a greater military utility in comparison to autocannon systems.

Para a delimitação de um processo de tomada de decisão na escolha de projetos Lean Six Sigma, é necessário definir os fatores críticos, tanto de sucesso (como por exemplo: envolvimento e comprometimento da gestão, entendimento das ferramentas e técnicas do Lean Six Sigma, ligação do projeto com a estratégia de negócios) quanto de fracasso (como por exemplo a falta do envolvimento da gestão, resistência à mudança cultural, inexistência de gestão de projetos). Desta forma, este trabalho foi conduzido por meio de modelagem com validação de dados reais, com o objetivo de propor uma adaptação de métodos de auxílio à tomada a decisão para seleção de projetos Lean Six Sigma baseado nos fatores críticos de sucesso e fracasso. Para tanto, com base na revisão da literatura, foram identificados os fatores críticos de sucesso e fracasso para seleção de projetos Lean Six Sigma. Em seguida, uma análise de dois métodos de tomada de decisão multicritério, PROMETHEE e ANP, foi realizada por meio da aplicação dos modelos em um portfólio de projetos de uma empresa multinacional de grande porte. Como resultado, houve assertividade de 95% na seleção dos melhores projetos do portfólio, comparado aos projetos executados pela empresa mostrando-se que os dois modelos são aderentes ao problema. Como resultado, é possível constatar que o PROMETHEE se mostrou mais assertivo, principalmente nas comparações quantitativas, tendo aplicabilidade tanto para decisões individuais quanto em grupos. O ANP, por fazer a análise de preferência dos critérios de forma pareada (utilizando a escala comparativa de Saaty) torna mais fácil seu em grupos grandes de decisores, porém a comparação utilizando a escala de Saaty dificulta a análise de critérios quantitativos, bem como para pequenos grupos ou em decisões individuais.
To define a decision-making process in the Lean Six Sigma projects’ choice, it is necessary to define the critical success factors (e. g., management involvement and commitment, understanding the tools and techniques of Lean Six Sigma methodologies), and critical failure factors (e. g., lack of management involvement, cultural change resistance, project management weakness, etc.). In this way, this work was conducted through the modeling method with the objective of proposing an adaptation of decision-making aid methods process to select Lean Six Sigma projects based on the critical success and critical failure factors. Therefore, based on the literature review, the critical success and critical failure factors for the selection of Lean Six Sigma projects were identified. An analysis of two multi-criteria decision-making methods, PROMETHEE and ANP, was performed through the application of the models in a project portfolio of a large multinational company, presenting 95% assertiveness in the selection of the best portfolio projects compared to the executed projects by the company, showing that the two models are adherent to the problem. In addition, PROMETHEE has been more assertive, mainly in quantitative comparisons, and the use of the method are applied for both individual and group decisions; the ANP, by doing the preference analysis of the criteria in pair-to-pair way, using the Saaty’s comparative scale, makes it easier in large groups of decision makers. However, the comparison using the Saaty scale makes it difficult to analyze quantitative criteria as well as small groups or in individual decisions

Full textAbstract:
This thesis examines the plight of the innocent person who has been wrongly convicted. It starts from the premise that such a fate is abhorrent and that the criminal justice system should have effective mechanisms in place to correct such errors. The Court of Appeal (Criminal Division) (CACD) has stated that it is not part of its function to consider ‘innocence’. Only the safety of a conviction is within its purview. The Criminal Cases Review Commission (CCRC) cannot correct an error itself, but can invite the CACD to consider doing so if it, CCRC, considers that there is a ‘real possibility’ of the CACD quashing the conviction. My hypothesis was that, in the light of these stated positions, neither the CACD nor CCRC does treat ‘innocence’ as a discrete criterion in determining appeals and applications respectively. I tested this hypothesis by examining CACD judgments delivered in 2009 and judgments on CCRC conviction referrals in the period 1997-2011. I examined 404 case files at CCRC. I found that neither body gave consideration explicitly to whether the applicant/appellant was ‘innocent’. I then considered whether ‘innocence’ could and should be an explicit consideration for either body. I argue that while ‘innocence’ could be designated a material consideration it should not be. The most important change that Parliament should make is to CACD’s application of the appeal test: that is the real obstacle for appellants who claim they are innocent. I propose that the CACD should be required by statute to receive fresh evidence more readily, and in some fresh evidence cases required to remit the case for retrial. Such changes would impact positively upon CCRC, which would then be able to refer more cases in which the applicant might be innocent.

Full textAbstract:
Stability analysis methods may be categorized by two major stability analysis methods: small-signal stability and transient stability analyses. Transient stability methods are further categorized into two major categories: numerical methods based on numerical integration, and direct methods. The purpose of this thesis is to study and investigate transient stability analysis using a combination of step-by-step and direct methods using Equal Area Criterion. The proposed method is extended for transient stability analysis of multi machine power systems. The proposed method calculates the potential and kinetic energies for all machines in a power system and then compares the largest group of kinetic energies to the smallest groups of potential energies. A decision based on the comparison can be made to determine stability of the power system. The proposed method is used to simulate the IEEE 39 Bus system to verify its effectiveness by comparison to the results obtained by pure numerical methods.

Full textAbstract:
Cette thèse fait partie d’un programme de recherche international (IRG Cognac). Lancé par le motoriste SNECMA (groupe SAFRAN), ce projet regroupe l’ENS Cachan, UnB, ENSMA, CNRS, Snecma, Turbomeca et Messier Bugatti Dowti, et se concentre sur l’effet du gradient des contraintes sur endommagement par fretting fatigue. Le fretting-fatigue se réfère au processus d’endommagement localisés en bord de fuite entre deux corps en contact soumis à un chargement de fatigue. La maitrise de ce phénomène est d’une importance cruciale dans la détermination des durées de vie des disques de turbine. En bord de contact, le champ de contrainte hérité des forces de contact est maximal à la surface mais présente un fort gradient en s’éloignant du contact.Il a été montré dans cette thèse que pour l’alliage Ti-6AL-4V, les approches locales, basés sur le niveau de contrainte au points critiques ne sont pas applicable dans ces conditions. Une approche non locale, s’appuyant sur la théorie de la distance critique a donc été utilisée. En effet, des fissures courtes initiées au point critique peuvent propager jusqu’à rupture ou peuvent s’arrêter si la diminution des contraintes est suffisamment sévère. Une seconde difficulté réside dans la nature multiaxial et localement non proportionnel du chargement. Le fretting fatigue est généralement créé par la superposition d’un chargement de fatigue cyclique, d’une force normale à la surface souvent considérée constante, et d’une force cyclique tangentiel à la surface mais dont la fréquence peut être différente de celle de la fatigue.Les résultats des essais réalisés ont mis en évidence l’effet du gradient des contraintes sur la fissuration et ont étaient utilisés pour évaluer le potentiel de diffèrent critères pour le dimensionnement en fatigue des structures. La simulation du phénomène a en effet été réalisé en utilisant différente approches. La première s’appuie sur la Théorie de la distance critique et utilise un critère multiaxial. La seconde utilise l’amplitude du facteur d’intensité des contraintes, ΔK, pour prédire l’arrêt des fissures courtes. Finalement un récent modèle construit comme un critère de plasticité en pointe de fissure a été appliqué au problème de fretting fatigue. Ce critère a pour particularité de prendre en compte la contrainte T dans le développement asymptotique en pointe de fissureThis thesis is part of an international research program (IRG Cognac) initiated by the engine manufacturer SNECMA (SAFRAN group) involving ENS Cachan, UnB, ENSMA, CNRS, Snecma, Turbomeca et Messier Bugatti Dowty. The thesis focuses on the effect of a stress gradient in fretting fatigue. Fretting-fatigue refers to the damage process localized at the frontier of the contact between two contacting bodies subjected to fatigue loadings. The prediction of this phenomenon is of major importance in determining, for instance, the lifetime of fan's disc. In the vicinity of the contact front, the stress field inherited from the contact loads is maximal at the surface and displays a strong gradient from the surface. It was shown in this thesis, for a Ti-6AL-4V alloy, that local approaches, based on local stresses at the most critical point, are not appropriate to predict fretting fatigue lives. As a matter of fact, short cracks initiated at the most critical point may stop if the stress decay from the surface is strong enough or may continue their growth, up to the failure of the component, if the stress gradient from the surface is not string enough. A second difficulty is the multiaxial and non-proportional nature of the loading conditions. Fatigue-fretting stems from the combination of loads that have neither the same spatial distribution nor the same time-dependency. In fretting-fatigue tests, three loading components are considered, the fatigue loading of the component (cyclic), the normal part (assumed to be constant) and the in-plane part (cyclic) of the loads between the two contacting components. To quantify the effect of the stress gradient, tests were carried out on a fatigue testing contact bench developed at the University of Brasilia, with experimental conditions ensuring different stress gradient while keeping the maximal stress the same. Damage mechanisms were studied using post-mortem analysis and optical microscopy on the contact elements tested. The prediction of the fretting fatigue life was done using different approaches. The first one is based on the Critical Distance Method and a fatigue criterion. The second is based on a K-based short crack arrest method. Finally, a new criterion was proposed. This method considers a generalized von Mises yield criterion for the crack tip region and accounts for the T-stresses in the asymptotic LEFM development

Full textAbstract:
The quality of the processes involved in language regeneration strategy formation is critical to the creation of an effective language regeneration strategy and this, in turn, is critical to the achievement of successful language regeneration outcomes. The overall aim of this research project was to evaluate, using a range of effectiveness criteria, the processes involved in the creation of a marae-based te reo Māori regeneration strategy in the hope that others involved in similar projects in the future would benefit and in the hope that the Whakamārama whānau will themselves derive benefit from it in reviewing what has already been achieved. In Chapter 1, the background to the research project and its rationale are outlined and the research questions and research methods are introduced. Chapter 2 provides a critical review of selected literature in the area of strategic planning aspects of language regeneration and relevant aspects of mātauranga Māori. Using an ethnographic approach, the processes and immediate outcomes (in terms of a survey report and a regeneration plan for Whakamārama marae) of the language regeneration project are outlined in Chapter 3. In Chapter 4, effectiveness criteria are derived on the basis of the literature review in Chapter 2. These include criteria relating to leadership, participation, Kaupapa Māori values, environmental analysis and outcomes. The criteria are then applied to the analysis and evaluation of the processes and outcomes outlined in Chapter 3 in order to identify their strengths and weaknesses. The overall conclusion is that Whakamārama's language regeneration activities to date can be regarded as successful in many ways, including the fact that they have resulted in the production of high quality documentation that is widely appreciated by the whānau in the form of a maraebased language survey and a marae-based te reo Māori regeneration plan. Working voluntarily and often under difficult circumstances, core group members demonstrated that they possessed the essential characteristics of commitment, motivation and determination, in addition to the willingness and ability to use existing skills and knowledge effectively and to develop further skills and knowledge as the project proceeded. Perhaps most important, they developed a caring and effective working culture. However, the weaknesses of the project included a lack of preparation and planning prior to the commencement of the project which resulted in a build up of work at a number of stages. This, in turn, lead to delays in producing outcomes and some loss of momentum. It also led, indirectly, to the views of two or three members of the core group being overrepresented in the reo plan goals. The information and analysis provided here have relevance to any language community involved in micro-level language regeneration activities of a similar type. It is hoped therefore that this thesis may help others to not only avoid the problems experienced by the Whakamārama whānau but also to benefit from their successes.

Full textAbstract:
Cette thèse est consacrée à l’étude du modèle d’accrochage en environnementfaiblement corrélé. Le modèle d’accrochage s’applique à de multiples situationstelles que la localisation d’un polymère au voisinage d’une interface unidimensionnelle,la transition de mouillage ou encore la dénaturation de l’ADN, le pointcommun étant la présence d’une transition entre une phase localisée et une phasedélocalisée.Nous commençons par donner un aperçu des résultats disponibles sur lescourbes et exposants critiques pour le modèle homogène puis pour le modèledésordonné lorsque le désordre est une suite de variables aléatoires indépendanteset identiquement distribuées (i.i.d.). Dans ce dernier cas, nous donnons égalementune borne sur la courbe critique quenched à haute température, dans un régimeoù le désordre est dit pertinent.Nous étudions ensuite le modèle d’accrochage désordonné dans le cas où ledésordre est gaussien et les corrélations ont une portée finie, à l’aide de la théoriedes processus de renouvellement markoviens. Nous donnons dans ce cas une expressionde la courbe annealed à l’aide de la plus grande valeur propre d’une matricede transfert ainsi que l’exposant critique annealed. Nous généralisons ensuite lescritères de pertinence et de non pertinence du désordre prouvés dans le cas i.i.d.Nous nous intéressons ensuite à des désordres dont les corrélations ont uneportée de corrélation infinie. Dans un premier temps, nous généralisons la démarcheutilisée dans le cas d’une portée de corrélations finie et obtenons le comportementcritique annealed dans le cas d’un désordre gaussien sous des hypothèses dedécroissance forte des corrélations. Nous utilisons pour cela les propriétés spectralesdes opérateurs de transfert pour des décalages sur des suites d’entiers etdes potentiels à variations sommables. Dans un deuxième temps, nous donnonsquelques résultats dans le cas où le désordre est donné par une chaîne de MarkovIn this dissertation we study the pinning model with weakly correlated disorder.The pinning model applies to various situations such as localization of a polymernear a one-dimensional interface, wetting transition and DNA denaturation, whichall display a transition between a localized phase and a delocalized phase.We start by giving a survey of the available results concerning critical pointsand exponents, first for the homogeneous setup and then for the inhomogeneousone, in the case when disorder is given by a sequence of independent and identicallydistributed (i.i.d.) random variables. In the latter case, we also provide a hightemperaturebound on the quenched critical curve in a case of relevant disorder.We then study the random pinning model when disorder is gaussian and hascorrelations with finite range, using the theory of Markov renewal processes. Weexpress the annealed critical curve in terms of the largest eigenvalue of a transfermatrix and we give the annealed critical exponent. We then generalize the criteriafor disorder relevance/irrelevance that were proved for the i.i.d. case.Next we are interested in disorder sequences with infinite range correlations.At first we generalize the method used to deal with finite range correlations andobtain the annealed critical behaviour in the case of gaussian disorder assumingfast decay of correlations. We use to this end the spectral properties of transferoperators for shifts on integer sequences and potentials with summable variations.Secondly we provide some results when disorder is a Markov chain

I examine a problem or dilemma of legitimation faced by the critical theorist who takes as the object of his or her critique a totality of which she or he is a part. The dilemma is that the theorist must either illegitimately exempt her critical theory from the determining influences of the totality or lose normative authority. The critics I examine in detail are: Adorno and Horkheimer; Kant; Hegel; feminist standpoint epistemologists, in particular, Sandra Harding; Irigaray; Foucault; and Arendt. I conclude that a purely theoretical or epistemic ground for the legitimacy of totalizing critique is impossible; philosophical critique must involve an extra-rational faith or a political commitment. However, I also argue that the project of theoretical grounding should not be abandoned. I continue this project by drawing out of the critical theorists I examined some preliminary concepts and strategies (such as mimesis, hysteria, free action, and psychoanalytic practice) that may, after further development, serve to provide a theory of the legitimacy of critical philosophy.

In response to the rapid development of science and technology and widespread use of computers and internet, digital content industry becomes flourishing. According to MIC reports, by 2010, the market size of global e-learning will be up to 500 billion US dollars. It indicates that e-learning has almost replaced the traditional learning methods. Therefore, the relevant issues about e-learning has been received more attention. A number of previous studies on e-learning put more emphasis on educational theories or technical aspects, and most of their analyses are based on statistical methods. In addition, although the service quality has been broadly applied in many industries, there is not much research focusing on the service quality of e-learning improvement. Accordingly, the research aims to construct an analytical model of service quality promotion for e-learning. First of all, the critical factors (attributes) that affect e-learning service quality are synthesized from related literatures. Questionnaire is then designed to survey e-learning users in order to understand the “customers’ requirements (Voice of customer, VOC)” of service quality. Rough set theory (RST) is then employed to reduce the attributes, that is, to find out core attributes of service quality. Secondly, quality function deployment (QFD) is adopted to develop “techniques requirements (Voice of engineer, VOE)” with respect to “customers’ requirements” of service quality. And, the relationships between “customers’ requirements” and “quality improvement techniques” are built up in consultation with the experts. Finally, grey relational analysis (GRA) is used to evaluate “quality improvement techniques” against “customers’ requirements” comprehensively to prioritize the order of improvement techniques. The results reveal that the top five of critical criteria to e-learning service quality are followed by: “Curriculum development”, “Evaluation”, “Guidance and tracing”, “Instructional design”, and “Teaching materials”. It shows that “Curriculum development” is the first priority when e-learning platform managers or engineers are going to design or planning their e-learning product in the near feature. The proposed model can be an important reference for digital content related industries while developing strategies of service quality promotion and performance improvement.

In the last decade, the mobile phones are evolved from pure voice phone application to data communications, mobile computations, and entertainment. Mobile devices such as smart phones, pads, or the like gradually incorporate new wireless technologies. One of such new technology is Near Field Communication (NFC) which provides the simplicity and security communication. Near Field Communication (NFC) is a new short-range wireless communication technology that enabled contactless, safe and intuitive peer-to-peer communication between NFC-enabled devices. The advent of NFC has given rise to several interesting applications under short-range radio technology. Many literatures focus on discussing the information developing in NFC field. However, research which has empirically documented the link among NFC mobile services, business model and business strategy is scant. Therefore, the aim of this article attempts to explore the critical criteria of using NFC technology in NFC mobile services. This research involved the quantitative methods and qualitative methods. The quantitative analysis of the questionnaires was conducted through Structural Equation Modeling methodology and DEMATEL methodology in order to indicate the critical criteria based on the opinions of the users and the experts. Results of this study proposed TRAUM model by structural equation modeling methodology. The model was based on the users' opinions. In the emergence period, the promotion and education for the consumers, the service in convenience and security were necessary. The enterprise should also focus on the affection of the community because the community can enhance the acceptance and using willingness. The DEMATEL network relationship map based on the experts' opinions found security, authentication, capabilities of the partners, and service offering were the critical criteria of decision making. The two quantitative analyses obtained the consistent results that the enterprise should put more resource in the convenience, service offering, infrastructure, security, and provide the corresponding NFC environment. The infrastructure should be based on the service providing. This study applied the finding of TRAUM and DEMATEL network relationship map to discuss the business strategy of NFC mobile services. The study also took NFC-Micro SD technology as the case to discuss the NFC mobile payment services. The patent of NFC-Micro SD technology provides both the convenience and security for the consumers. It tallies with the results of the TRAUM model and DEMATEL methodology. To conclude, this study may be of importance in explaining the business model in NFC field, as well as proposing TRAUM model, the combination with the DEMATEL network relationship map to offer the holistic view of business strategy. TRAUM model provides the better explanation about the technology acceptance and mobile services. The analytic model and TRAUM can apply to evaluate the similar research fields, such as technology acceptance, technology product promotion, e-service, mobile services and so forth. The study provides the researcher and the enterprise with a better understanding of critical criteria and business strategy in order to improve the decision quality.

ABSTRACT Design criteria of slab-column connections in the ACI Building Code (2011) were mostly developed based from experimental results of interior connections. When dealing with corner slab-column connections, supplementary documents published by Joint ACI-ASCE Committee 352 and Joint ACI-ASCE Committee 421 provide better explanations than the ACI Building Code (2011) and become useful references for practical engineers. However, different design values can be obtained using the recommended analytical approaches provided by each document. A summary of this issue is presented in this research. With the design parameters discussed in this research, ACI 421 generally provides higher punching shear demand than with ACI Building Code but the discrepancy can be effectively minimized by increasing the slab thickness. Connection with rectangular column attracts larger moment transfer along the stronger axis.

There are more and more people willing to accept mini-invasive aesthetic services. Although potential customers increase, providers increase as well. Even hospitals, also, establish mini-invasive aesthetic services department to provide related service to attract consumers/patients. The service providers face keep competition. In order to increase market share or to improve profits, it is important for the providers to understand what criteria which consumers care about and their priorities when customers evaluate a mini-invasive aesthetic service provider. The purpose of this study is to explore critical criteria a customer (patient) considers when choosing a mini-invasive aesthetic service providers. Because of the asymmetric information and remedy risk in mini-invasive aesthetic services, the criteria consumers consider in provider choice are highly diverse and complex. This study selects 6 criteria and 24 sub-criteria derived from literature and the interview result of focus group to conduct DEMATEL and ANP analysis. And then we applied DEMATEL to analyze the relation among criteria. According to forty-six experts’ opinion, the result shows that doctor’s expertise, medical staff’s characteristics, services completeness and service provider’s characteristics are the main factors affecting other criteria. We, then, apply DEMATEL analysis result to construct ANP-model and calculate criteria weights according to inputs provided by the fifty-three experts’ questionnaire. It is found that service provider’s consulting service, service provider’s reputation, post-sale service, process and efficiency and pervious success are the top 5 critical selection sub-criteria. Mini-invasive aesthetic service providers could invest more resources in these critical selection criteria to attract customers and to increase market share and profit.

In the past, the industry batch reactors had been criticized for they kept causing many catastrophes in the process of production, storage, and transportation. Among these many factors that cause disasters, the most important one was that we couldn’t have a complete comprehension of thermodynamic and engineering kinetic properties in the reaction system. In this dissertation, we investigate the runaway and stable criteria by analyzing and calculating both the energy and mass balance equations in a batch reaction system. Consequently, any potential hazard in a batch reaction system can be evaluated and prevented effectively. The criteria of thermal runaway reaction in a reactor can be determined from the relationships of the temperature rising rate, the chemical consumption rate of reactants, and the heat removed rate by the ambient cooling medium in the whole reaction system. In the investigation, we apply and modify the Semenov thermal explosion theory to study the runaway and stable criteria in a batch reaction system. First of all, the critical runaway temperatures and stability criteria of batch reaction system either with chemical consumption or without chemical consumption are analyzed and evaluated. Then the reactions of cumene hydroperoxide decomposition, RDX production, toluene mononitration, and hydroperoxide decomposition are analyzed. The values of thermodynamic and reaction kinetic properties in various reactions are used to evaluate the runaway criteria by the derived equations. Their relationships between the critical modified Semenov number ( ) and the dimensionless ambient cooling temperature ( ) in reaction system are correlated by means of curve fitting technique. Consequently, their critical runaway temperatures and stability criteria can be appropriately determined from our evaluated equations. This study has a lot of contributions to the reactant production, energetic material transportation, storage process, and reactor design.

This study builds on the Resource Base View theory for organizations and how the external social factors can affect the operational efficiency of the Metro Manila MRT Line 3 thereby to propose recommendations on the principles of Project Management that in turn can influence their strategic competitive advantage. By utilizing the Analytical Hierarchy Process, the critical concerns of the commuters were identified, weighted and ranked according to their vector priorities. The importance of these criteria represents the sectors of the system that may need immediate investment or solution from the railway company’s decision makers. As such, using the AHP approach, five major criteria were identified which includes pricing, timeliness, service, comfort and security each with sub-criteria of its own. Findings show that more than 12 percent of the 142 respondents deem that pricing of the fare compared to other modes of transport in the city concerns them the most followed by security issues that specifically deals with the pick-pocketing inside the station and the trains while facilities like lavatory or more stations were all rated of low. These factors influence their perception and preference towards the system both positively and negatively depending on the quality they get and therefore recommended to be paid attention to.
