CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO<br>A integração de informação geográfica e mapas digitais
nos
Sistemas de Informação Geográfica (SIGs) produz soluções
para vários grupos de usuários. Vem crescendo o número de
usuários não especializados que utilizam SIGs na Web ou
em
desktop para localizar endereços, planejar rotas,
planejar
viagens, encontrar lugares, e assim por diante. Estas
aplicações menos complexas e destinadas a qualquer pessoa
carecem fundamentalmente de avaliação, pois da qualidade
da interação depende seu sucesso comercial. Apesar desta
necessidade, praticamente não encontramos pesquisas sobre
como avaliar estas aplicações mais simples de SIGs. Neste
trabalho propomos um método de Inspeção Semiótica para
Interfaces baseadas em Mapas (o ISIM) capaz de analisar o
efeito de representações usadas nestas interfaces na
comunicação da informação geográfica. O ISIM combina
técnicas analíticas e empíricas. As técnicas analíticas
são usadas para definir contextos de uso e perfis de
usuários, bem como para interpretar observações
empíricas.
Técnicas empíricas são usadas em testes e entrevistas com
usuários, para comparar parte dos dados obtidos com as
técnicas analíticas. O ISIM, que inicialmente abrange
dos
SIGs apenas as interações baseadas em mapas, identifica
uma classe de problemas básicos deste tipo de interação
e,
como é o caso de vários outros métodos semióticos, dá
indicações sobre possibilidades de solução para eles.<br>The integration of digital maps and geographical
information into Geographical Information Systems (GIS)
produces solutions for several groups of users. There is an
increasing number of non experts that use GIS on the Web or
in desktop applications to locate addresses, plan routes
and trips, find places, and so on. Less complex
applications designed for general use critically need
evaluation, because their commercial success depends
heavily on the quality of human-computer interaction. In
spite of such critical need, it is very hard to find
research about how to evaluate these kinds of simpler
applications. We propose a semiotic inspection method
(whose acronym in Portuguese is ISIM) that analyzes the
effect of representations in map-based interfaces to
communicate geographic information. ISIM combines analytic
and empirical techniques to carry out evaluations. Analytic
techniques are used to define contexts of use and users'
profiles, as well as to interpret empirical observations.
ISIM also uses an empirical technique of tests and
interviews with users. ISIM, whose scope encompasses only
GIS map-based interaction, can identify a class of basic
problems of interaction and, as is the case with many
semiotic methods, hint at design solutions for them.

Full textAbstract:
Autonomous vehicles have grown into a hot topic in both research and industry. For a vehicle to be able to run autonomously, it needs several different types of systems to function properly. One of the most important of them is simultaneous localization and mapping (SLAM). It is used for estimating the pose of the vehicle and building a map of the environment around it based on sensor readings. In this thesis we have developed an novel approach to measure and evaluate the quality of a landmark-based SLAM algorithm in a static environment. The error measurement evaluation is a multi-error function and consists of the following error types: average pose error, maximum pose error, number of false negatives, number of false positives and an error relating to the distance when landmarks are added into the map. The error function can be tailored towards specific applications by settings different weights for each error. A small research concept car with several different sensors and an outside tracking system was used to create several datasets. The datasets include three different map layouts and three different power settings on the car’s engine to create a large variability in the datasets. FastSLAM and EKF-SLAM were to test the proposed SLAM evaluation method. A comparison to just the pose error was made to asses if our method can provide more information concerning establishing SLAM quality. Our results show that the pose error is often a good enough indicator of SLAM quality. However it can occasionally be misleading with errors related to mapping (location of landmarks, false negative and false positive landmarks). By using the method presented in this thesis, errors relating to the mapping will be more easily detected than by looking at the pose error.<br>Autonoma fordon har vuxit till ett viktigt ämne både inom forskning och industri. För att ett fordon ska kunna köras autonomt behövs det att flera olika system fungerar korrekt. En av de viktigaste av dem är simultaneous localization and mapping (SLAM). Det används för att uppskatta fordonets position samt för att bygga en karta av miljön runt fordonet. I det här examensarbetet har vi utvecklat en ny metod för att mäta och utvärdera kvaliteten på en landmärkes-baserad SLAM-algoritm i en statisk miljö. Metoden består av följande feltyper: medelvärdet av positionsfelet, det maximala positionsfelet, antal falskt negativa fel, antal falskt positiva fel samt ett fel relaterat till avståndet när ett landmärke läggs till i kartan. Genom att använda vikter för varje fel kan metoden skräddarsys till en specifik applikation. En liten konceptbil med flera olika sensorer och ett yttre spårningssystem användes för att skapa flera dataset. Dataseten innehåller tre olika kartlayouter och tre olika effektinställningar på bilen för att skapa stor variation i dataseten. FastSLAM och EKF-SLAM användes vid testningen av den nya metoden för kvalitetsbedömning av SLAM. Den nya metoden jämfördes mot positionsfelet för att analysera ifall den nya metoden är ett bättre sätt att mäta SLAMkvalitet. Våra resultat visar att positionsfelet ofta är en tillräckligt bra indikator för SLAM-kvalitet, men det kan ibland vara vilseledande gällande fel i kartläggningen (positioner av landmärken, falskt negativa fel och falskt positiva fel). Genom att använda metoden som presenteras i det här examensarbete är fel som är relaterade till kartläggningen lättare att upptäcka än om man enbart kollar på positionsfelet.

Full textAbstract:
Airburst projectiles increase the effectiveness of air defense, by forming clouds of small pellets. In this work, in order to evaluate the effectiveness of airburst projectiles, Single Shot Kill Probability (SSKP) is computed at different burst distances by using three lethality functions defined from different measures of effectiveness. These different measures are target coverage, number of sub-projectile hits on the target and kinetic energy of sub-projectiles after burst. Computations are carried out for two different sub-projectile distribution patterns, namely circular and ring patterns. In this work, for the determination of miss distance, a Monte Carlo simulation is implemented, which uses Modified Point Mass Model (MPMM) trajectory equations. According to the results obtained two different distribution patterns are compared in terms of effectiveness and optimum burst distance of each distribution pattern is determined at different ranges.

Full textAbstract:
The overall aim of the research was to develop a low cost, tailorable, formative evaluation method for web designers. The last fifteen years has witnessed the rapid development of the World Wide' Web, an information resource that users surf and mine for work, leisure, entertainment and transaction purposes. Its evaluation as a computer based product has led to the assumption by some researchers, that web site and HCI usability are the same (Nielsen, 2000; Brinck, Gergle and Wood, 2002). This is reflected in many web site evaluation guidelines and instruments that characterise usability in terms of learnability, efficiency, memorability, errors and satisfaction (Rubin, 1994). However, the web is used differently from other software e.g. surfing the web is not necessarily task directed and users may access the Internet purely to obtain intellectual and emotional gratification (Spool et ai, 1999). Therefore, it is quite possible that what determines user satisfaction is very different in each context. Additionally, commerce plays a fundamental part in a lot of websites so that their goals may be different from conventional computer system design e.g. to increase the user base or encourage repeat visits. Further, with limited budgets, website designers are unlikely to involve their users during the design process and not all owebsite designers have access to an evaluator, appropriate testing facilities or evaluation knowledge to support their design. Given these arguments, this research developed and validated a low-cost evaluation 'ethod for web designers to use for formative evaluation, prior to site launch. The method addressed both HCI and commercial website goals such as the encouragement of repeat visits. To achieve this, a series of studies were conducted. Firstly, contemporary evaluation methods were evaluated to explore their possible limitations with respect to website design. T.hen the users' and designers' needs from websites and website evaluation methods were identified. This led to the development of a tai/orable method that could be applied to a wide range of small commercial websites, that took into account the issues users of websites were concerned about, and also designers' requirements of an evaluation method. The method was formalized as a set of guidelines, verified in the evaluation of a website. The potential usefulness of the method was then verified by demonstrations to selected website designers who confirmed it was useful, practical, and needed. In summary, this research contributes to knowledge firstly by identifying the need for 'designer friendly' evaluation methods in this context; secondly be showing the mismatch between current methods (based on Hel) and the requirements of website design and thirdly by producing a method to meet the need.

Full textAbstract:
<p>This master’s thesis is performed at Department of Management and Engineering Linköping University, for Scania Omni at Scania Production Slupsk (S.P.S). Omni is responsible for development, manufacturing and marketing of city, suburban and intercity buses. After acquisition of the production unit in Slupsk in 2002 lower production cost per bus is possible. But without control over the organisation costs are rising due to late delivery fees and high stock levels. At the outset, the thesis included three clearly defined objectives:</p><p>- Map the present situation at Scania Production Slupsk regarding material flow from supplier to assembly line including a part and storage analysis.</p><p>- Benchmark the current routines at Scania Production Slupsk with other successful companies. Furthermore, conduct literature research in order to find theories and philosophies that support problem analysis and thesis solution.</p><p>- Develop standard routines for material control methods (MCM) and material supply methods (MSM).</p><p>A complimentary objective is to work as a catalyst during the time of the thesis.</p><p>The mapping of the present situation showed that MCM and MSM are very tight connected to each other. It was questioned whether this structure was the best way to manage the material flow. After a parts and storage analysis, material was divided into different segments depending of price, consumption and movement. </p><p>The benchmarking studies showed different ways to manage the material flow. Implementation of unit load, kanban and clear defined interface between departments showed potential to improve the material handling and increase effectiveness.</p><p>New routines and part segment definitions described in a logistics manual (Appendix I) were made align with a comparison between previous and recommended definitions.</p><p>The result showed that some parts needs to be controlled differently. Primary recommendations are that logistics manual shall be used when new parts are introduced into the Scala system. Responsible personnel are suppose to give suggestion concerning decision making of MCM and MSM and with help of the logistics manual the work can be more efficient, resulting in a material flow that is flexible and have potential for improvements.</p><p>Secondary, to avoid material handling to some extent implementation of two-bin system is recommended. Additional recommendations regarding two-bin system is to handle material according to unit load, which enable FIFO, traceability and higher turn over rate</p>

Full textAbstract:
When doing finite element analysis upon the structure of Saab’s aeroplanes a coarse global model of mainly shell elements is used to determine the load distribution for sizing the structure. At some parts of the aeroplane it is however desirable to implement a more detailed analysis. These areas are usually modelled with solid elements; the problem of connecting the fine local solid elements to the coarse global model will shell elements then arises. This master thesis is preformed to investigate possible Global-Local methods to use for the structural analysis on Gripen. First a literature study of current methods on the market is made, thereafter a few methods are implemented on a generic test structure and later on also tested on a real detail of Gripen VU. The methods tested in this thesis are Mesh refinement in HyperWorks, RBE3 in HyperWorks, Glue in MSC Patran/Nastran and DMIG in MSC Nastran. The software is however not evaluated in this thesis, and a further investigation is recommended to find the most fitting software for this purpose. All analysis are performed with linear assumptions. Mesh refinement is an integrated technique where the elements are gradually decreasing in size. Per definition, this technique cannot handle gaps, but it has almost identical results to the fine reference model. RBE3 is a type of rigid body elements with zero stiffness, and is used as an interface element. RBE3 is possible to use to connect both Shell-To-Shell and Shell-To-Solid, and can handle offsets and gaps in the boundary between the global and local model. Glue is a contact definition and is also available in other software under other names. The global respectively the local model is defined as contact bodies and a contact table is used to control the coupling. Glue works for both Shell-To-Shell and Shell-To-Solid couplings, but has problem dealing with offsets and gaps in the boundary between the global and local model. DMIG is a superelement technique where the global model is divided into smaller sub-models which are mathematically connected. DMIG is only possible to use when the nodes on the boundary on the local model have the same position as the nodes at the boundary of the global model. Thus, it is not possible to only use DMIG as a Global-Local method, but can advantageously be combined with other methods. The results indicate that the preferable method to use for Global-Local analysis is RBE3. To decrease the size of the files and demand of computational power, RBE3 can be combined with a superelement technique, for example DMIG. Finally, it is important to consider the size of the local model. There will inevitably be boundary effect when performing a Global-Local analysis of the suggested type, and it is therefore important to make the local model big enough so that the boundary effects have faded before reaching the area of interest.

Full textAbstract:
Web development is different from traditional software development. Like in all software applications, usability is one of the core components of web applications. Usability engineering and web engineering are rapidly growing fields. Companies can improve their market position by making their products and services more accessible through usability engineering. User testing is often skipped when approaching deadline. This is very much true in case of web application development. Achieving good usability is one of the main concerns of web development. Several methods have been proposed in literature for evaluating web usability. There is not yet an agreement in the software development community about which usability evaluation method is more useful than another. Doing extensive usability evaluation is usually not feasible in case of web development. On the other hand unusable website increases the total cost of ownership. Improved usability is one of the major factors in achieving satisfaction up to a sufficient level. It can be achieved by utilizing appropriate usability evaluation method, but cost-effective usability evaluation tools are still lacking. In this thesis we study usability inspection and usability testing methods. Furthermore, an effort has been made in order to find appropriate usability evaluation method for web applications during product development and in this effort we propose appropriate web usability evaluation method which is based on observation of the common opinion of web industry.<br>There is no standard framework or mechanism of selecting usability evaluation method for software development. In the context of web development projects where time and budget are more limited than traditional software development projects, it becomes even harder to select appropriate usability evaluation method. Certainly it is not feasible for any web development project to utilize multiple usability inspection method and multiple usability testing methods during product development. The good choice can be the combinational method composed of one usability inspection method and one usability testing method. The thesis has contributed by identifying those usability evaluation methods which are common in literature and current web industry<br>ifazeem@gmail.com

Full textAbstract:
In today’s world, embedded systems which have very large and highly configurable software systems, consisting of hundreds of tasks with huge lines of code and mostly with real-time constraints, has replaced the traditional systems. Generally in real-time systems, the WCET of a program is a crucial component, which is the longest execution time of a specified task. WCET is determined by WCET analysis techniques and the values produced should be tight and safe to ensure the proper timing behavior of a real-time system. Static WCET is one of the techniques to compute the upper bounds of the execution time of programs, without actually executing the programs but relying on mathematical models of the software and the hardware involved. Mathematical models can be used to generate timing estimations on source code level when the hardware is not yet fully accessible or the code is not yet ready to compile. In this thesis, the methods used to build timing models developed by WCET group in MDH have been assessed by evaluating the accuracy of the resulting timing models for a number of combinations of hardware architecture. Furthermore, the timing model identification is extended for various hardware platforms, like advanced architecture with cache and pipeline and also included floating-point instructions by selecting benchmarks that uses floating-points as well.

Full textAbstract:
Input devices are an integral part of human and computer interaction. This research explores the relationship between user ability and user performance when using input devices in real tasks in a natural environment. User performances using a mouse, a tablet-with-stylus and a touch screen were measured in browsing and dragging tasks. User cognitive, perceptual and motor abilities were measured usmg widely used and simple psychometric tests. Input devices were rated before and after the tasks. Users provided their justification and described their experience in an interview after completing the task. The psychometric tests, i.e. Mini Mental State Examination for cognitive, Identical Picture for perceptual and Simple Reaction Time for motor abilities, measured user abilities effectively. The result shows that perceptual and motor abilities influence user performance for highly complex tasks. Consistent with previous studies, the mouse is the best device for a dragging task. Content analysis of user justification indicates that users prefer the mouse because of its effectiveness, ease of use and familiarity. User self-reported behaviour illustrates an extended user behaviour model which includes detailed descriptions of the activities. The click in Simple Reaction Time and the first move in the dragging task have been successfully modelled using microstrategies.

Chheda, Bijal Mavji Bharti. "Evaluation of narrative interview as an assessment method." Thesis, University of Hull, 2004. http://hydra.hull.ac.uk/resources/hull:8080.
Full textAbstract:
This thesis examines the role of the narrative interview as an assessment method. The main aim of the study was to ascertain the value of subjective and holistic methods of assessment in facilitating and enabling psychological processes. Traditional psychometric techniques of assessment are compared with narrative interviews, based on Bartram's (1990) 'Factors to consider when choosing an assessment method'. Data collection was in two phases. During phase one, 40 participants were administered traditional assessment tasks: Differential Aptitude Tests, Career Interest Inventory and structured guidance interviews. This enabled an evaluation of traditional assessment techniques to allow a comparison of the open-ended narrative interview. For phase two 10 participants from phase one and 30 new participants were administered the narrative interview in order to ascertain its value. Assessment profiles which were formulated, feedback questionnaire results and focus group feedback results portrayed particular strengths of the narrative interview. The narrative interview is seen to provide rich, holistic and deep assessments. It also instilled motivation and encouraged participants thereby facilitating the overall psychological process. The narrative interview thus fulfils aspects of assessment, which traditional assessment techniques fail to provide. The phenomenological and subjective nature of narrative interview aids reconceptualisation of the term 'assessment' from classification and categorization to understanding and exploration.

É notório no meio acadêmico e prático que ao longo dos últimos anos a logística deixou de ser vista como um processo operacional e passou a ser reconhecida como uma matéria de suma importância na integração das cadeias de suprimentos e uma ferramenta importante para atender as necessidades dos clientes e buscar diferencial competitivo. Em um ambiente globalizado e competitivo, as empresas buscam soluções que possam ajudá-las a atingir seus objetivos organizacionais. Neste contexto, a terceirização de serviços logísticos vem sendo amplamente utilizada com diversas finalidades. Porém, ao realizar terceirizações logísticas as empresas se deparam com a dificuldade de desenvolver mecanismos de avaliação de desempenho que estejam alinhados com a estratégia das empresas e que possam avaliar dados quantitativos e qualitativos para mensurar e comparar o desempenho de seus terceirizados. Diante deste cenário, este trabalho apresenta um estudo de caso onde foi utilizado o método AHP (Analytic Hierarchy Process) como ferramenta de apoio para avaliação, ranking e reconhecimento de transportadores terceirizados de uma multinacional líder de mercado de gases industriais e medicinais. Existe uma relação entre a satisfação do cliente final e o desempenho dos transportadores. Portanto, é fundamental o desenvolvimento de uma ferramenta para mensurar esse desempenho e reconhecer os melhores. O trabalho propõe a avaliação dos transportadores através de um único índice que traduz indicadores quantitativos e qualitativos. A escolha do método AHP foi fundamental para facilitar a estruturação do problema e se mostrou uma ferramenta de fácil entendimento tanto para o pesquisador como para os demais envolvidos.<br>It is well known in the academic and practical means that over the last few years the logistics is no longer seen as an operational process and has become recognized as a matter of paramount importance in the integration of supply chains and an important tool to meet customer needs and seek competitive advantage. In a globalized and competitive environment, companies are looking for solutions that can help them achieve their organizational goals. In this context, the outsourcing of logistics services has been widely used for various purposes. However, when performing logistics outsourcing companies are faced with the difficulty of developing mechanisms for evaluating performance that are aligned with company strategy and to assess quantitative and qualitative data to measure and compare the performance of their third party. This paper presents a case study where the AHP (Analytic Hierarchy Process) method was used as a support tool for evaluation, ranking and recognition outsourced carriers of a multinational leader in industrial and medical gases market on Brazil. There is a relationship between the end-customer satisfaction and the performance of carriers. Therefore, it is fundamental to develop a tool to measure this performance and recognize the best carrier. The paper proposes the review of carriers through a single index reflecting quantitative and qualitative indicators. The choice of AHP was instrumental in facilitating the structuring of the problem and proved to be an easily understood tool for researchers and for the others involved.

As technology progresses, we become surrounded with an ever increasing number of devices. Information can now be persistently represented beyond a single screen and a single session. In the educational context, we see a rapid adoption of the panoply of devices, but often without any careful thought. Devices in isolation are unlikely to enable effective learning.
This research explores how devices function in technological display and device ecologies or ecosystems to support human thinking, learning and sensemaking. Based on the theories of Vygotsky's sign mediation triangle, we contribute a method that may allow one to evaluate how technology configurations support (or hinder) students' thinking. Our method proposes the concept of objectification as a way to identify the potential or opportunity for learning in technology ecologies.
The significance of such an evaluation methodology is considerable, given the nascent field of sensemaking and the lack of consensus on evaluation in such contexts: our research advances a principled approach by which device ecologies can be examined for their potential to provide 'learning experiences', and enables one to articulate affordances for the design of technological spatial environments that can help to support higher thought. Our contribution thus is in terms of methodology, theory, evaluation and the design of technology ecologies.<br>Master of Science

Heuristic Evaluation (HE) is a popular method of usability inspection. However, its outcomes are dependent on the expertise of evaluators. This study explored and described the difference in quality of outcomes (reports) of a collaborative HE conducted by evaluator groups of distinct composition, regarding different numbers of expert evaluators in each group. Twenty-seven (27) evaluators voluntarily contributed with this study, nine (9) expert and 18 novice evaluators. Thus, I organized seven (7) HE groups according to four (4) different levels of the factor presence of an expert, which ranged from no expert up to three (3) experts in the same group. Each group agreed to provide their reports for this study. Thereafter, I conducted a comparative analysis on the reports based on standard methods of the field and on a cluster analysis of similarities. I described the F-measure for each group report according to a relaxed and a strict criteria. Also, I described the dendrograms formed from the cluster analysis and the respective similarities indicated by each cluster. The results showed that the quality of reports from collaborative HE conducted by experts and novices together can be more similar to the quality of reports from a traditional HE with multiple expert inspectors (Benchmark Group) then to the quality of reports from a collaborative HE conducted by a group composed only by novice evaluators (Baseline Group). Finally, I discuss additional findings and implications for future studies in the field.<br>A Avaliação Heurística (AH) é um método popular de inspeção de usabilidade.

Vinte e sete (27) avaliadores contribuíram voluntariamente com este estudo, nove (9) experientes e 18 novatos. Assim, foram organizados sete (7) grupos de AH, de acordo com quatro (4) níveis diferentes do fator presença de avaliador experiente, variando de nenhum experiente até três (3) avaliadores experientes no mesmo grupo. Cada grupo de avaliadores concordou em entregar seus relatórios de AH para este estudo. A partir de tais relatórios, foi conduzida uma análise comparativa baseada em métodos específicos da área, e também baseado em uma análise de agrupamento com base em medidas de similaridade. Como resultado, descreveu-se as medidas F (F-measure) referentes ao relatório de cada grupo respeitando critérios estritos e relaxados de comparação. Além disto, foram descritos os dendrogramas resultados das análises de agrupamento. Os resultados mostraram que a qualidade de relatórios de AH colaborativas conduzidas por avaliadores experientes e novatos juntos pode ser mais similar à qualidade de relatórios de AH tradicional conduzida por múltiplos avaliadores experientes (Grupo Benchmark) do que à qualidade de relatórios de AH colaborativa conduzida por grupos formados apenas por avaliadores novatos (Grupo Baseline). Finalmente, discutiu-se resultados adicionais e implicações para pesquisas futuras na área.

Full textAbstract:
<p>Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction. Deficiency of GSH in the body results in lysis of red blood cells leading to reduced life length of these cells and hemolytic anemia. In this study,we evaluated a method for determining the GR activity used in the investigation of hemolytic anemia. Blood samples containing both normal and high reticulocyte concentration were washed, to extract red blood cells. To analyze GR activity, we used an enzyme activity assay based on spectrofotometry. The method showed reliable results for GR activity and hopefully will be used in diagnostic routines.</p>

Full textAbstract:
The purpose of this study was to evaluate the problem solving method applied to a self-instructional material in nutrition education.
A comparative evaluation design was employed to determine the value of a problem solving model reflected in a commercially developed material, referred to as the 'Calcium Calculator'. Data were collected using a quasi-experimental randomized group pretest, posttest research design. A panel of judges then evaluated the impact of the problem solving method in nutrition education.
Three research questions were generated for the purpose of this study. The first involved comparing impacts produced by the two forms of the 'Calcium Calculator'. Measures of impact, selected based on learner objectives of the 'Calcium Calculator', were learners': attitudes toward dietary calcium and osteoporosis; perception of problem solving ability and self-reported dietary calcium intake.
The second research question was posed to investigate the nature of relationships between learners' levels of self-esteem and measures of instructional impact. Influences of selected biodemographic variables on change in the measures of impact were explored in the third research question.
Eighteen groups of women (n=241) from community centres were randomly assigned to one of three intervention groups: Groups A and B were exposed to active problem solving methods while group C viewed a film, a passive information-oriented instructional technique. The latter group was included in.the study since active learning was hypothesized to result in greater impact than passive learning. Pretest data were collected using a self-administered questionnaire and food intake form. Posttest data were collected an average of 4.7 weeks later using a modification of the pretest questionnaire which included a self-esteem scale, along with the food intake form. Forty-four percent of women (n=l06) who completed pretest questionnaires returned for the posttest session.
Participants in all three intervention groups experienced increases in attitude scores from pre- to posttest, and these changes were significant within groups B and C. Perceptions of problem solving ability were maintained within intervention groups B and C, yet decreased significantly within intervention group A. Significant increases in self-reported dietary calcium intakes occurred in all three intervention groups among non-pregnant women whose pretest dietary calcium intakes were below their Recommended Nutrient Intake.
Impacts produced by form A and B of the 'Calcium Calculator' were significantly different on only one dependent variable: perception of problem solving ability (p≤0.05). Changes in the dependent variables produced by problem solving versus non-problem solving interventions were not significantly different. Changes in dietary calcium intake and attitude toward dietary calcium and osteoporosis were not significantly correlated with self-esteem levels. However, positive significant correlations were identified between learners' levels of self-esteem and change in learners' perceptions of their problem solving ability (p≤0.0l).
Measures of impact were infrequently influenced by the biodemographic variables. Of the associations that were identified, most involved dietary characteristics of participants. Yet change in perception of problem solving ability was also affected by a combination of three demographic variables: age, employment status and education.
A panel of users (n=9) of educational materials was asked to make judgements on selected study results. Although judges did not distinguish between impacts produced by the two problem solving materials, they acknowledged that: (1) an important relationship exists between self-esteem and learners' perceptions of their problem solving ability and (2) the problem solving method is valuable when directed to specific kinds of learners.
The quasi-experimental research design used in this study appeared appropriate for the evaluation of innovative instructional methods. Two main advantages of the design were its comparative nature and its use of a panel of experts to judge the relative effectiveness of both forms of the 'Calcium Calculator' as well as the value of the problem solving method and self-esteem in material design.<br>Education, Faculty of<br>Curriculum and Pedagogy (EDCP), Department of<br>Graduate

Full textAbstract:
The problem of controlling tsetse flies in Africa is an old one. The tsetse fly transmits the trypanosome parasites which cause sleeping sickness in humans and disease in cattle. Because cattle are a favoured food source for tsetse much work has been done looking at the use of insecticide treated cattle as a control strategy for the tsetse fly. Such treatment methods possess many advantages; they are safe and relatively environmentally benign, they can be applied by individual farmers without the need for logistically demanding and costly traditional control programmes and, in addition to tsetse flies the insecticides are effective against a wide range of other harmful cattle parasites. The cost of the insecticide is however a significant constraint to the number of livestock keepers who can afford to employ the technique and as a result many cattle remain untreated. Following the discovery that tsetse had a significant predilection for feeding on the legs and belly of cattle, it was hypothesised that restricting the insecticide to only those areas could offer comparable protection to treating the whole animal. Such an approach would use up to 80% less drug and thus make the treatment per animal much cheaper. In addition, preferentially targeting areas favoured by tsetse, and leaving the rest of the animal untreated, preserves some important ecological balances between cattle and their parasites which traditional treatment methods destabilise. This thesis describes the design, implementation and analysis of a longitudinal study run over 8 months in south east Uganda that sought to compare the effect of applying insecticide to cattle only on the regions favoured by tsetse flies. Cattle were recruited to the study and assigned one of four treatment groups; a whole body application of deltamethrin insecticide pour-on; a restricted application of deltamethrin spray, applied to the front legs, ears and belly; a prophylactic trypanocide injection of isometamidium chloride, and a control group, that received no further treatments. All animals in the study were however cleared using twin doses of a trypanocide diminazene aceturate at the start of the study.

potencial associado à capacidade de visão. A partir da
década de 60, foram iniciados os primeiros estudos no
sentido de proporcionar às máquinas esta forma de

sem solução. No presente trabalho, propõe-se um novo
estimador estatístico para a determinação do Fluxo Ótico.
Este estimador possui complexidade O(n) e associa um grau
de confiabilidade a cada estimativa realizada. É aplicável
a qualquer sinal digital (não apenas imagens ou vídeo,

The research area involved in this task is called Computer
Vision. In Computer Vision there are many situations where
it is necessary to evaluate a vector field which describes
existing displacements between two consecutive frames of a
generic video sequence. This vector field is called Optical
Flow. The Optical Flow determination is still a problem
with unknown solution. This work proposes a new statistic
algorithm to estimate the Optical Flow. The proposed
algorithm has O(n) complexity and associates a degree of
reliability to each estimation.The algorithm can be applied
to any digital signal (not only images or videos, but also
sound, volume etc) and is achieving promising results.

A novel reliability evaluation method for large nonlinear engineering systems excited by dynamic loading applied in time domain is presented. For this class of problems, the performance functions are expected to be function of time and implicit in nature. Available first-or second-order reliability method (FORM/SORM) will be challenging to estimate reliability of such systems. Because of its inefficiency, the classical Monte Carlo simulation (MCS) method also cannot be used for large nonlinear dynamic systems. In the proposed approach, only tens instead of hundreds or thousands of deterministic evaluations at intelligently selected points are used to extract the reliability information. A hybrid approach, consisting of the stochastic finite element method (SFEM) developed by the author and his research team using FORM, response surface method (RSM), an interpolation scheme, and advanced factorial schemes, is proposed. The method is clarified with the help of several numerical examples. (C) 2016 Faculty of Engineering, Ain Shams University. Production and hosting by Elsevier B.V.

The procedure for measurement uncertainty evaluation at micrometer
calibration by the kurtosis method is considered. The measurement model as the
deviation of the micrometer readings from the length of the reference gage block
is recorded. The measurement model takes into account the corrections for the
micrometer resolution to be calibrated, lack of flatness and departure from
parallelism of its measuring faces, as well as for the temperature difference
between the gage block and the calibrated micrometer.
The input values and their standard uncertainties are estimated. The
calculation of the combined standard uncertainty and expanded uncertainty is
carried out taking into account the kurtosis of the input quantities. The report
presents an uncertainty budget, which can serve as a basis for creating a software
tool that facilitates calculations.
The proposed procedure was validated by the Monte Carlo method, which
showed that it is are adequate for an intended use.

A single field experiment was established in 2001 at the Safford Agricultural Center to evaluate the effects planting method and seeding rate have on plant population and yield of an Upland cotton cultivar Deltapine DP655BR. Two planting methods; planting into moisture (pre-irrigate) and dry plant/water-up, were main effects with three seeding rates of 10, 20, and 30 lbs./acre as sub-effects. These effects were evaluated with respect to stand establishment and yield. Analysis of variance showed no significant differences with respect to planting method for either plant population or yield, so data was combined across main effects. Significant differences were observed in plant population and yield as a function of seeding rate. A linear increase in yield with plant population was observed. These results are not consistent with previous research performed examining plant population effects on yield. This experiment will be conducted again in 2002 in an effort to validate results observed in 2001.

Full textAbstract:
碩士<br>國立臺灣大學<br>職業醫學與工業衛生研究所<br>88<br>The beta gauge attenuation method of mass determination depends upon the near exponential decrease in the number of beta particles transmitted through a thin sample as the unit area density is increased. The performance of beta attenuation monitor can be suffered from several potential measurement artifacts, such as (1) particle size effects, (2) substrate inhomogeneity, (3) non-uniformity of filter deposit, (4) atomic number dependence, and (5) water vapor absorption by the aerosol deposits. The purpose of this work is to identify the principal factors resulting in overall inaccuracy, and hopefully to provide measure to remedy these artifacts.
A primitive beta gauge was built and tested in a calm air chamber. A constant output aerosol generator and an ultrasonic atomizing nozzle were used to produce challenge aerosols of different size distributions. An Aerodynamic Particle Sizer and a Scanning Mobility Particle Sizer combined system were used to measure the aerosol number concentration and size distribution, ranging from 5 nm to 30 mm. Beta ray passed through aerosol deposition on filter was recorded by a radiationmeter. TEOM and filter collection method were used to monitor aerosol mass concentration. The principal operational parameters include challenge aerosol size distribution, environment relative humility, filter location, amount of aerosol deposit, and uniformity of aerosol deposition.
The results showed that the beta intensity through the filter sample decreased exponentially with increasing aerosol deposit, as expected. The upper limit of surface mass deposition of the homemade beta attenuation system was estimated to be 0.8 mg/cm2. Among the challenge aerosols, lead nitrate has the highest attenuation (0.968 cm2/mg), followed by NaCl and then PST. Aerosols of smaller size appeared to attenuate more beta ray than the larger particles, a phenomenon needs to be studied further.
The comparison study between beta gauge and TEOM showed that beta gauge normally reads higher aerosol concentration than does TEOM, probably due to the fact that TEOM measures the mass under a heated environment; and therefore some of the material might vaporized and not to be measured by TEOM. Without the heating system, as if TEOM, beta gauge is likely to suffer the hygroscopic effect. To overcome this problem, a Sample Equilibration System (SES) developed for TEOM, should be effective in the beta attenuation system. The effect of uniformity of aerosol deposit on the beta attenuation methods could be significant. The Beta penetration increased with decreasing coverage (by aerosol deposit) given that mass of aerosol deposit was fixed.

碩士<br>國立臺灣海洋大學<br>河海工程學系<br>96<br>The purpose of the paper is to estimate the axial bearing capacity of a drilled shaft based on cone penetration test (CPT) data interpreted via eight different methods available in the literature. The data obtained from CPT test conducted before and after shaft installation were used for capacity prediction. In addition, the estimated bearing capacity is also compared to that of the axial pile load test results. Based on the comparison, the result by Bustamante and Gianeselli (1982) method appears to be the best estimation.
Use of in-situ testing results for pile or drilled shaft foundation bearing capacity estimation has been drawn the interests of geotechnical engineers in the past decades. Increasing use of cone penetration test (CPT) for site characterization, methods by using CPT data for pile foundation design have also been getting popular, such as the researches of Schmertman(1978) 、Bustamante & Gianeselli(1982)、De Ruiter & Beringen(1979) 、Tumay & Fakhroo (1982)、Aoki & De Alencar(1975)、Price & Wardle(1982)、Philipponnat(1980)、Penpile (1978) and Titi(1999)。Schmertman(1978) 、Bustamante & Gianeselli(1982)、De Ruiter & Beringen(1979) 、Tumay & Fakhroo (1982)、Aoki & De Alencar(1975)、Price & Wardle(1982)、Philipponnat(1980)、Penpile (1978) and Titi(1999)。
All these methods utilize the data of CPT conducted before pile installation. It’s known that installation of pile or drilled shaft also disturbing the surrounded soil properties. In this paper, a drilled shaft bearing capacity is estimated via eight different available methods based on CPT data obtained before and after shaft installation. The estimated capacity is also compared to that of the full scale axial pile load test. The capacity estimated by the method proposed by Bustamante and Gianeselli (1982) shows the best fit to the test results.

Sewer pipeline has been built for a long time and the penetration rate has reached over 66% today. Partial pipeline has been corroded or damaged and the measure of repair or rehabilitation should be taken to maintain the normal function or to extend the service of pipeline. Open cut or non-open cut construction method can be selected in accordance with the requirement of repair, renovation or replacement. In urban area with heavy traffic, open cut method is hard to exercise due to the shortage of construction space.
In order to avoid excavation and to speed up construction, expanding method or in-situ-form method is suggested to adopt for sewage pipeline maintenance based on the previous studies. In this study, the maintenance project of Wanhua District, Taipei City , was used as a case study to demonstrate the effectiveness of expanding, in-situ-transform method in the narrow streets or lanes. PVC instead of PE was selected for the renovation material to avoid the heating procedure. The quality assurance of in-site implementation of pipe renovation was verified and the construction project could be successfully completed within a short time.

The first model, Fuzzy Multiple Criteria Decision Making, is designed for the situation when there aren''t enough experienced underwriters nor the objective underwriters, as the possible loss is approved by the insurance company. The second model, Fuzzy Group Decision Making, which combines the FMCDM and the rational consensus decision making process, is designed for the situation while there may be a larger loss. This model is more efficient, avoiding the conventional process: conference, voting, and interaction. Being more accurate and efficient, these two models can help the Contractor''s All Risk Insurance Company to evaluate the projects. The accuracy of the models is more than 80%, being verified by various types of construction projects, including 213 architectural constructions, 143 road constructions, 209 bridge constructions, 181 tunnel constructions, 195 nautical constructions, 196 hydraulic constructions. These two models will make the underwriting more accurate, also provide a better reference for the estimation of the insurance fee.

needs. Thus, many firms modify their formal production
system to fit the changing demand by exploiting the
advantages of modern technologies. A decision support
framework is proposed in this study to integrate the strategy
planning into the system evaluation process to make the
selection of modern manufacturing systems more solid. The
decision support framework consists of three phases. A "TOWS"
matrix for strategy planning is suggested, in which ''T'' stands
for threats, ''O'' for opportunities, ''W'' for weaknesses
and for strengths, in the first phase. Once the strategy is
determined, a number of alternatives will be available.
The executive support system ''AHP'' is used to narrow the
usually relatively large group of candidate configurations
down to the three or four ''most attractive'' configurations.The
remaining three or four configurations are analyzed in more
details in the third phase. The analysis in phase three is
quantitative. The packages ''Promodel'' and ''Starcell''are
selected for the analysis in phase 3. An implementation of the
proposed decision support framework to a real shoe-making

碩士<br>國立臺北科技大學<br>電腦與通訊研究所<br>98<br>This work investigates automated techniques for evaluating the skill of a singer performing with Karaoke VCD music. The proposed system is capable of analyzing the pitch, dynamic volume, and harmonicity in a singing performance, and indicates how well or bad a singer performs. The pitch information reflects whether or not the notes sung by a singer are correct; the dynamic volume conveys the emotion that should be presented in performing a song; the harmonicity reflects whether or not a singing performance is in rhythm. Our special effort in this work is put on harmonicity analysis. It is observed that only when a singing performance is in rhythm, the mix of singing voice and accompaniments can be harmonious and melodious. Although there are copious works studying rhythm extraction from music, all of them only suitable for instrument-solely music rather than singing. For this reason, we develop methods to evaluate the harmonicity between singing voice and accompaniment. The basic strategy is to represent harmonious sound and inharmonious sound as probabilistic models and then perform stochastic recognition. On the other hand, this study also proposes a method for distinguishing between singing and humming, in order to check if a Karaoke user does sing the lyrics rather than simply hums the tune of a song. In our experiments, we invited a number of participants having different singing capabilities to perform solo singing. We also employed several professional judgers to grade each piece of solo singing in our collection. It is found that the grading results obtained with our system are roughly close to those with manual grading, which confirms the validity of our system.

Eight graphics are taken to evaluate the aesthetic characteristics and composition of the evaluation contains four patterns: linear complexity H(t), the complexity of the feature point H(p), the location of the complexity H(r), the graphic complexity H(s)；and mechanical features for four graphic assessment: balance I(b), the degree of motion I(m), the smoothness of the I(s) and the elasticity intensity of the graphic I(t) et cetera. By using the strength of the performance of each characteristic values can be used to describe the aesthetic expression pattern. Whereby the difference between the graphics can be easily identified and isolated. Finally the eight cases of the trademark graphic feature value of the evaluation, from the result shows that this method can effectively evaluate graphical features, the strength of each characteristic values can help the graphic designers to interpret the differences of the graphics based on the degree of approximation or make decision based on the graphic design work.

Full textAbstract:
碩士<br>開南大學<br>空運管理學系<br>102<br>In recent years, the data envelopment analysis has been adopted by many researchers to evaluate the performance of airlines using various inputs and outputs, for different airlines. And the results of those DEA performance evaluations usually don’t link with traditional profit performance indicator.
This thesis evaluates the performance of 9 airlines in three different continents by using DEA method with different set of input-output from 5 cost-related inputs and 3 revenue-related outputs. The purpose of this thesis is to explore the relevance between performance evaluation of DEA and the traditional profit performance. The empirical results show that the rank of performance evaluation using DEA-CCR method with single input single output is completely the same as the performance ranking using traditional profit evaluation. However, there is no certain link between the performance of traditional profit evaluation and the performance evaluated using DEA method with multiple input multiple output which varies with the input-output set. The best profitable airline judging from traditional analysis and efficient-input and inefficient-input items of all airlines can be identified by using the evaluation results of DEA method with various multiple input-multiple output sets.
