Today's digital business environment is imposing a great transformation challenge on the enterprises to effectively use vast amount data in order to gain critical business insights to stay competitive. In their aim to take advantage of data many large organizations are launching data management programs. In these attempts organizations recognize that taking full advantage of data requires enterprise wide changes in organizational aspects, business processes, and technology. The lack of recognition of this enterprise-wide scope haunts most data management programs. Research shows that most of these programs fail and get abandoned after long efforts and investments. This study aims to highlight critical reasons why these programs fail and a different approach to address the fundamental problems associated with the majority of these failures. It is important to be successful in the data efforts due to the fact that data driven businesses are gaining significant competitive edge. Data Centric Business Transformation Strategy (DCBT) is a holistic approach for the enterprise to transform into a data driven and agile entity. DCBT is also away to achieve better alignment in the enterprises. DCBT aims to achieve two goals to transform the organization; become a smarter organization by instilling continuous learning and improvement culture in all aspects of the business and achieve agility in enterprise-wide organizational learning and technology. To achieve these two goals, understanding the current state of the organization in the tree fundamental DCBT areas of organizational learning capacity, business processes and technology is essential to incrementally and continuously improve each one in concert. Required improvements should be introduced to smaller parts of the organization delivering the value of data. Strategically chosen pipeline of projects would allow the ramp up of the organization to a continuously learning and changing organization. In the age of digital economy, agile organizations can learn quicker from large amounts of data to have the competitive edge. This study will also look into how a data management program relates to DCBT and can be used in concert to enable DCBT.

In slow or no-growth economies, firms cannot rely solely on recurring business from large, core customers who often delay or cancel capital investments in belt-tightening times. To achieve growth, firms must lever domain knowledge to expand business markets to find new customers. A core method to accomplish this expansion is through service models that can provide recurring revenues without as much up-front investment for customers. However, in a product-centric firm, the process of transforming a product into a service can be complex, and is the motivation for this research. No other complete explanation of this process has been published to date. The goal of researching this process is to give direction to managers who are considering transforming a product into service. The research led to building a service model using the Collaborative Adaptive Sensing of the Atmosphere (CASA) Radar System as its subject. The CASA Radar System is an X-Band Phased-Array Radar used for weather forecasting and environmental warning, led by University of Massachusetts with the assistance from several universities and industry partners. The radar system provides capabilities that did not exist previously in larger and less price effective systems, but was only available to be acquired directly, for upwards of $600 million. The CASA model sought to show how transforming the radar system from a product to a service could create value for the UMASS led team by selling more systems in a new service model to new customers, including weather-sensing firms and non-profits that want access to the CASA Radar System and would even pay for it, but were unable to support its standard capital costs.

Full textAbstract:
The purpose of the X-Form package is for use in the classroom as an instructional aid for teaching the algorithms and data used to represent, transform, and display objects in three-dimensional space. The program provides various areas containing graphic and textual representations of the data structures used in the creation and transformation of a three-dimensional object. Another area, containing the menu items, serves as an interface to the available demonstration items. These items include various object and viewing parameters which can be input by the user. The user then sees the result of the entered data, including animated graphics and changes in data structures. The graphic areas show the object at various stages of development, so that the user can understand the progression of the required manipulations. The textual representations are also designed to assist the user in understanding how useful information is derived from entered data. Through testing and statistical analysis, XForm has proven to be an effective tool for instruction of three-dimensional graphics.Department of Computer Science

Takeshita, Seijiro. "The transformation of the Japanese business system." Thesis, Birkbeck (University of London), 2007. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.498465.
Full textAbstract:
This thesis investigates the structural transformation of the Japanese business system. Internal decay of the system, caused by the unprecedented length of a recession through the 1990s and reluctance to transform has resulted in a decline of bank-led governance and the deterioration of a cross-holding structure. Concurrently, external pressure was imposed by a dramatic increase of foreign ownership; advocates of convergence theory which adopts a single optimal strategy of increasing profitability. They are also critics of Japanese non-liberal capitalism, urging Japanese firms to transcend into the structure of liberalist Anglo-American governance. Investigations for this thesis suggest these internal and external pressures did not steer Japanese firms to abandon their core competencies of sustaining human resources and the willingness to compete. The seniority method, once thought to have been terminated with the introduction of meritocracy, was kept virtually intact by preserving a grading system. The core structure of their human resource management (HRM) was not overturned, despite pressures imposed by foreign shareholders, because Japanese firms did not discard their institutional capabilities " they may want to be able to use for comparative and competitive advantage in future. The study reveals that many Japanese firms partially moved towards Anglo-American governance, but continued to maintain their competencies at their core. This hybridization indicates Japanese governance may be undergoing a period of stress and transformation that will see the adoption of some of the features of Anglo-American corporate governance, although there is little evidence that it is likely to converge completely with the Anglo-American system in its current configuration (Kester, 1996). Moreover, the study suggests that the Anglo-American model, based on liberal capitalism, is not sufficient to induce the paradigm shift necessary for Japanese firms to carry out a transformation in their systems.

It is widely believed that we are currently living in the digital age. Advances in technologies enabling connectivity, data aggregation and analysis, and aritificial intelligence/ machine learning are making it possible to obtain insights into human and machine behaviour like never before. Companies are rushing to take advantage of this new resource called data for competitive advantage. Yet, while many are aiming to pursue a Digital Transformation strategy within their organization, there appears to be a range of different opinions that professionals/ experts carry when it comes to identifying capabilities required to become a Digital Enterprise. This thesis is aimed at helping professionals in two ways. First, it identifies required capabilities at functional level from first principles. Second, it defines maturity levels for key generic capabilities at the company level for professionals to measure and guide their organization's progress towards becoming a Digital Enterprise.

In the world of digital interactive entertainment, there has yet to be a well-defined system for the dynamic production of music. It is commonplace for a user to be able to interact with the visual aspect of a presentation or video game, yet the audio and musical aspects have been neglected, often being static musical scores or triggered audio events with no inherent interaction at all. The purpose of this study is to provide the groundwork for an extensible, modular, adaptive musical transformation system that is small and lightweight enough to be embedded within larger applications (such as games or web browsers), providing another level of interactivity for the user.

Full textAbstract:
One of the most difficult tasks a programmer can be confronted with is the migration of a legacy system. Usually, these systems are unstructured, poorly documented and contain complex program logic. The reason for this, in most cases, is an emphasis on raw performance rather than on clean and structured code as well as a long period of applying quick fixes and enhancements rather than doing a proper software reengineering process including a full redesign during major enhancements. Nowadays, the old programming paradigms are becoming an increasingly serious problem. It has been identified that 90% of the costs of a typical software system arise in the maintenance phase. Many companies are simply too afraid of changing their software infrastructure and prefer to continue with principles like "never touch a running system". These companies experience growing pressure to migrate their legacy systems onto newer platforms because the maintenance of such systems is expensive and dangerous as the risk of losing vital parts of sources code or its documentation increases drastically over time. The FermaT transformation system has shown the ability to automatically or semi-automatically restructure and abstract legacy code within a special intermediate language called WSL (Wide Spectrum Language). Unfortunately, the current transformation process only supports the migration of assembler as WSL lacks the ability to handle data types properly. The data structures in assembler are currently directly translated into C data types which involves many assumptional “hard coded” conversions. The absence of an adequate type system for WSL caused several flaws for the whole transformation process and limits its abilities significantly. The main aim of the presented research is to tackle these problems by investigating and formulating how a type system can contribute to a safe and reliable migration of legacy systems. The described research includes the definition of key aspects of type related problems in the FermaT migration process and how to solve them with a suitable type system approach. Since software migration often includes a change in programming language the type system for WSL has to be able to support various type system approaches including the representation of all relevant details to avoid assumptions. This is especially difficult as most programming languages are designed for a special purpose which means that their possible programming constructs and data types differ significantly. This ranges from languages with simple type systems whose program sare prone to unintended side-effects, to languages with strict type systems which are constrained n their flexibility. It is important to include as many type related details as necessary to avoid making assumptions during language to language translation. The result of the investigation is a novel multi layered type system specifically designed to satisfy the needs of WSL for a sophisticated solution without imposing too many limitations on its abilities. The type system has an adjustable expressiveness, able to represent a wide spectrum of typing approaches ranging from weak typing which allows direct memory access and down casting, via very strict typing with a high diversity of data types to object oriented typing which supports encapsulation and data hiding. Looking at the majority of commercial relevant statically typed programming languages, two fundamental properties of type strictness and safety can be identified. A type system can be either weakly or strongly typed and may or may not allow unsafe features such as direct memory access. Each layer of the Wide Spectrum Type System has a different combination of these properties. The approach also includes special Type System Transformations which can be used to move a given WSL program among these layers. Other emphasised key features are explicit typing and scalability. The whole approach is based on a sound mathematical foundation which assures correctness and integrates seamlessly into the present mathematical definition of WSL. The type system is formally introduced to WSL by constructing an attribute grammar for the language. Type checking and type inference are used to annotate the Abstract Syntax Tree of a given WSL program with type derivations which can be used to reveal and indicate possible typing errors or to infer types if the program did not feature explicit type declarations in the first place. Notable in this approach is also the fact that object orientation is introduced to a procedural programming language without the introduction of new semantics. It is shown that object orientation can be introduced just by adjusting type checking rules and adding some syntactical notations. The approach was implemented and tested on two case studies. The thesis describes and discusses both cases in detail and shows how a migration which ignores type systems could accidentally introduce errors due to assumptions during translation. Both case studies use all important aspects of the approach, Including type transformations and object identification. The thesis finalises by summarising the whole work, identifying limitations, presenting future perspectives and drawing conclusions

Full textAbstract:
In today’s world we see that Embedded Systems forms a major part in the life of a human being. Almost every device today has an electronic chip embedded in it. When it comes to automotive, these electronic devices are multiplying. This has resulted in innovative methods of developing Embedded Systems. Among them, Model Based Development has become very popular and a standard way of developing embedded systems. Now, we can see that most embedded systems, especially the automotive systems, are being developed using Model development tools like Simulink. In the design and development of Driver Assistance System, Model Based Design (MBD) plays an important role from system design and simulation to code generation. Modeling tool Matlab/Simulink is now among the most popular tools. Due to the proprietary nature of Simulink and challenges in requirement elicitation phase the industry is looking towards an open source alternative, such as Scicos. Since, most of the OEMs are still using Simulink, there is a need for interoperability between Simulink and Scicos. The present work proposes metamodels for Simulink and Scicos, and Model transformation using these Metamodels for the inter-operability.
In order to develop the model transformation the metamodels for Simulink and Scicos were developed using EMF Ecore. These metamodels conform to OMGs MOF Standards. These metamodels were used in developing the transformation definition using the language QVTo. First a simple model was developed, and transformation rules were applied and verified using it. Then a Simulink subsystem of a cross wind assistance system was subjected to forward transformation. The outputs of the model before transformation and that after transformation were compared. They were found to give the same output as desired. Thus, verifying the transformation definition. An attempt was made to achieve reverse transformation. A subsystem in Scicos was considered for reverse transformation. After subjecting it to transformation, an intermediate model conforming to Simulink metamodel was obtained. This shows that the interoperability between Scicos and Simulink can be achieved.

The focus of Bank of America's change management initiatives has shifted away from acquiring and integrating new businesses, a process it calls transition, and towards internal enterprise transformation through a process the Bank calls transformation. One significant change management initiative currently underway is the California Northwest (CANW) transformation. The focus of the CANW initiative is to transfer the Bank's retail banking platform and accounts in California, Idaho, and Washington to the Model banking platform that it maintains across the rest of its enterprise. This thesis, using the California Northwest transformation as a case study, is an enterprise systems evaluation of change management practices at Bank of America. MIT Lean Advancement Initiative (LAI)'s Enterprise Strategic Analysis and Transformation (ESAT) methodology is used as a framework to evaluate the consideration of CANW stakeholders and the alignment of their needs with the CANW goals, processes, metrics, and strategic objectives. INCOSE's framework for writing quality system requirements is further applied to the California Northwest transformation goals. The result of this systems analysis is that while the set of strategic objectives is complete, additional processes, stakeholder values, and metrics need to be identified or developed. Although the set of CANW strategic objectives / goals is complete and all key objectives appear to have been included, the wording of individual goals needs to be clarified and the change management team must review each goal to ensure that it is both necessary and attainable. The second element of the research looks towards change management practices as a whole at Bank of America to identify whether BAC's transformation process is complete and effective. The study reveals that Bank of America should take a stakeholder centric view and consider the needs of all stakeholders to gain "buy-in" from all parties so as to create an "all hands on deck" environment for transformation initiatives. Other recommended actions include announcing change initiatives publically when possible, back-checking of actions by all parties, maintaining a single message, and adopting a standardization vs. transformation mindset.

Full textAbstract:
The objective of this dissertation is to introduce a unified framework for modeling and simulating discrete event logistics systems (DELS) by using a formal language, the System Modeling Language (SysML), for conceptual modeling and a corresponding methodology for translating the conceptual model into a simulation model. There are three parts in this research: plant modeling, control modeling, and simulation generation.
Part 1:Plant Modeling of Discrete Event Logistics Systems.
Contemporary DELS are complex and challenging to design. One challenge is to describe the system in a formal language. We propose a unified framework for modeling DELS using SysML. A SysML subset for plant modeling is identified in this research. We show that any system can be described by using the proposed subset if the system can be modeled using finite state machines or finite state automata. Furthermore, the system modeled by the proposed subset can avoid the state explosion problem, i.e., the number of the system states grows exponentially when the number of the components increases. We also compare this approach to other existing modeling languages.
Part 2:Control Modeling of Discrete Event Logistics Systems.
The development of contemporary manufacturing control systems is an extremely complex process. One approach for modeling control systems uses activity diagrams from SysML, providing a standard object-oriented graphical notation and enhancing reusability. However, SysML activity diagrams do not directly support the kind of analysis needed to verify the control model, such as might be available with a Petri net (PN) model. We show that a control model represented by UML/SysML activity diagrams can be transformed into an equivalent PN, so the analysis capability of PN can be used and the results applied back in the activity diagram model. We define a formal mathematical notation for activity diagrams, show the mapping rules between PN and activity diagrams, and propose a formal transformation algorithm.
Part 3:Discrete Event Simulation Generation.
The challenge of cost-effectively creating discrete event simulation models is well-known. One approach to alleviate this issue is to describe a system using a descriptive modeling language and then transform the system model to a simulation model. Some researchers have tried to realize this idea using a transformation script. However, most of the transformation approaches depend on a domain specific language, so extending the domain specific language may require modifying the transformation script. We propose a transformation approach from SysML to a simulation language. We show that a transformation script can be independent of the associated domain specific language if the domain specific language is implemented as domain libraries using a proposed SysML subset. In this case, both the domain library and the system model can be transformed to a target simulation language. We demonstrate a proof-of-concept example using AnyLogic as the target simulation language.

Full textAbstract:
Thesis (MSc)--University of Stellenbosch, 2000.ENGLISH ABSTRACT: Agrobacterium tumefaciens-mediated transformation technology has been used in a variety of applications throughout the fields of cellular and molecular plant biology as well as plant physiology. Research is conducted in order to extend this application range and overcome some of the intrinsic limitations of the Agrobacterium transformation system. Predominantly, these limitations can be attributed to the host range specificity of A. tumefaciens, as well as adverse effects induced on explant tissue by active plant defence mechanisms, triggered by the plant-pathogen-interaction. Typically, this active defence mechanism culminates in the hypersensitive response (HR), characterised by localised cell death and necrosis. Not all Agrobacterium species, however, share the same host range and some have evolved the ability to infect plant species not normally considered hosts of A. tumefaciens. This host range specificity can be exploited to extend the application of existing Agrobacterium transformation systems. In an attempt to establish an efficient transformation system for Vitis vinifera which, has proven very difficult to transform with A. tumefaciens, indigenous A. vitis strains have been evaluated as possible host-specific transformation agents. Strains of Agrobacterium vitis should be suitable for this type of endeavour, since they have evolved several unique characteristics directly linked to the infection of their hosts. These include the ability to utilise, tartrate, a host abundant carbon source, as well as the production of an acid polygalacturonase that could play a role during the infection process. The proposition that the evolution of A. vitis is a fairly recent event is also confirmed by the relatively little divergence observed between A. tumefaciens and A. vitis. In this study, a selection of A. vitis strains were evaluated in screenings designed to accentuate desirable traits in strains such as good infectivity of grapevine material (presumably an indicator of an efficient mechanism of gene transfer to be exploited in an engineered transformation system) as well as a favourable reaction (causing no necrosis) on grapevine somatic embryos. Two strains produced large tumours on grapevine cuttings and caused little necrosis on the somatic embryos. Significant variation in infectivity as well as callus necrosis was observed between the strains as well as in a genotype-specific manner on the host material. This genotypic-specific effect of either host or pathogen could be an indication of the degree of specialisation developed by plant pathogens to infect specific hosts. On the basis of these results, it was possible to select an A. vitis strain for further biochemical and genetic characterisation. Simple biochemical analysis classified the strain as an octopine strain. DNA-DNA hybridisation techniques combined with a plasmid walking technique resulted in the partial characterisation of the T-DNA of the selected A. vitis strain. A partial restriction enzyme map of the T-DNA was constructed and the T-DNA and flanking areas were cloned. Significant differences, most notably, the absence of a TB-area as well as the absence of the agrocinopine (aes) gene from the 5' area of the T-DNA, were observed. Partial sequencing data indicated the presence of at least four conserved T-DNA genes located on the TA-DNA, as well as the presence of three bacterial insertion (IS-)elements flanking the region. Two of these IS elements, both related to the IS 110 family of IS elements have not yet been reported in A. vitis. In fact, these two elements seem to be the 5' and 3' ends of a disrupted element and could therefore have played an evolutionary role in the development of this strain. This study provides fundamental background for the development of a more efficient transformation system specific for grapevine, exploiting same of-the unique characteristics of one of its pathogens, A. vitis.
AFRIKAANSE OPSOMMING: Agrobacterium tumefaciens-gebaseerde transformasiesisteme word in "n wye reeks van toepassings in die velde van sellulêre- en molekulêre plantbiologie asook plantfisiologie aangewend. Navorsing word voortdurend onderneem om die inherente beperkinge van die Agrobacterium-transformasiesisteem te oorkom en sodoende die toepassingsveld van die sisteem verder te verbreed. Die beperkinge tipies aan dié sisteem kan hoofsaaklik toegeskryf word aan die gasheerspesifisteit van A. tumeteciens, asook die negatiewe reaksies op eksplantmateriaal wat deur die plant se aktiewe verdedigingsmeganisme, soos ontlok deur die plant-patogeen interaksie, veroorsaak word. Hierdie aktiewe verdedigingsmeganisme lei gewoonlik tot In hipersensitiewe respons (HR) in die plant, wat deur gelokaliseerde selafsterwing en nekrose gekenmerk word. Alle Agrobacterium-spesies het egter nie almal dieselfde gasheerreeks nie en sommige rasse het as gevolg van evolusionêre ontwikkelings die vermoë verkry om plantspesies wat normaalweg buite die gasheerreeks van A. tumefaciens val, te infekteer. Hierdie tipe gasheerspesifisiteit kan uitgebuit word om die toepassingsmoontlikhede van bestaande Agrobacterium-transformasiesisteme te verbreed. In In poging om In effektiewe transformasiesisteem vir Vitis vinifera, In moeilik transformeerbare gewas, te ontwikkel, is inheemse rasse van Agrobacterium vitis ondersoek as moontlike gasheerspesifieke transformasie-agente. Rasse van A. vitis behoort uiters geskik te wees vir so "n toepassing, aangesien hulle verskeie unieke eienskappe, wat direk aan die infeksie van die gasheer gekoppel is, vertoon. Van hierdie eienskappe is onder meer die vermoë om tartraat, In koolstofbron volop in druifplante, te benut. A. vitis produseer verder ook In suur poligalaktorunase wat vermoedelik In rol in die infeksieproses speel. Die voorstel dat die evolusionêre ontwikkeling van A. vitis In redelike onlangse gebeurtenis is, word onderskryf deur die betreklike homogenisiteit met A. tumefaciens. In hierdie studie is "n groep A. vitis-rasse met behulp van siftingsprosedures wat daarop gemik is om gesogte eienskappe in rasse uit te wys, beoordeel. Die vermoë om druifplantmateriaal te infekteer (wat vermoedelik "n aanwyser van "n effektiewe meganisme van geenoordraging is wat in "n gemanipuleerde transformasiesisteem benut kan word), sowel as 'n gunstige reaksie (d.w.s geen nekrose) op druifplant somatiese embrio's is van die gesogte eienskappe waarvoor gesoek word. Twee rasse het groot tumors op druifplant-stingelsegmente veroorsaak terwyl hulle bykans geen weefselskade op somatiese embrio's geïnduseer het nie. Betekenisvolle verskille in infektiwiteit en in kallusnekrose is tussen die rasse sowel as in 'n genotipe-spesifieke-verhouding waargeneem. Hierdie genotipe-spesifieke effek, kenmerkend van óf die gasheer óf die patogeen, kan aanduidend wees van die vlak van spesialisasie wat heers by die infeksie van spesifieke gashere. Na aanleiding van bogenoemde resultate was dit moontlik om 'n A. vitis-ras te selekteer wat verder aan biochemiese en genetiese analises onderwerp kon word. Eenvoudige biochemiese analises het dit moontlik gemaak om die ras as oktopien te klassifiseer. DNA-DNA hibridisasietegnieke gekombineerd met 'n unieke plasmiedwandeltegniek het gelei tot die gedeeltelike karakterisering van die geselekteerde A. vitisras. In Gedeeltelike restriksie-ensiem (RE) kaart van die T-DNA kon gevolglik opgestel word. Die T-DNA en die aangrensende gedeeltes is boonop gekloneer. Betekenisvolle verskille, spesifiek die afwesigheid van In TB area, sowel as die afwesigheid van die agrosinopien-sintasegeen (acs) aan die 51-kant van die T-DNA, is waargeneem. Gedeeltelike basispaaropeenvolgingsdata het egter die teenwoordigheid van minstens vier gekonserveerde T-DNA-gene, asook die teenwoordigheid van drie bakteriese invoegingselemente (IS) aan weerskante van die area, geïdentifiseer. Twee van hierdie elemente, wat beide homologie vertoon met die IS110 familie van IS elemente, is nog nie vantevore in A. vitis aangetref nie. Dit wil boonop blyk of dié twee elemente die 51 - en 31 - areas van In onderbroke element vorm, wat dus In moontlike aanduiding is van hul potensiële rol in die evolusionêre ontwikkeling van die ras.

Kou, Xin. "Rogue Wave Solutions to Integrable System by Darboux Transformation." ScholarWorks @ UVM, 2014. http://scholarworks.uvm.edu/graddis/306.
Full textAbstract:
The Darboux transformation is one of the main techniques for finding solutions of integrable equations. The Darboux transformation is not only powerful in the construction of muilti-soliton solutions, recently, it is found that the Darboux transformation, after some modification, is also effective in generating the rogue wave solutions. In this thesis, we derive the rogue wave solutions for the Davey-Stewartson-II (DS-II) equation in terms of Darboux transformation. By taking the spectral function as the product of plane wave and rational function, we get the fundamental rogue wave solution and multi-rogue wave solutions via the normal Darboux transformation. Last but not least, we construct a generalized Darboux transformation for DS-II equation by using the limit process. As applications, we use the generalized Darboux transformation to derive the second-order rogue waves. In addition, an alternative way is applied to derive the N-fold Darboux transformation for the nonlinear Schrödinger (NLS) equation. One advantage of this method is that the proof for N-fold Darboux transformation is very straightforward.

Standardized information and mathematicalmodels, which model the characteristics of the power generationand power transmission systems, are requirements for futuredevelopment and maintenance of different applications tooperate the electrical grid. Available databases such as Nordpoolprovides large amounts of data for power supply and demand [1].The typical misconception with open availability of data is thatexisting power system software tools can interact and process thisdata. Difficulties occur mainly because of two reasons. The firston is the amount of data produced. When the topology of theelectrical grid changes e.g. when a switch opens or closes, the flowof electrical power changes. This event produce changes ingeneration, transmission and distribution of the energy anddifferent data sets are produced. The second problem is therepresentation of information [2]. There are a limited number ofsoftware tools that can analyze this data, but each software toolrequires a specific data format structure to run. Dealing withthese difficulties requires an effective way to transform theprovided data representation into new data structures that canbe used in different execution platforms. This project aims tocreate a generic Model-to-Text (M2T) transformation capable oftransforming standardized power system information modelsinto input files executable by the Power System Analysis Tool(PSAT). During this project, a working M2T transformation wasnever achieved. However, missing functionality in someprograms connected to sub processes resulted in unexpectedproblems. This led to a new task of updating the informationmodel interpreter PyCIM. This task is partially completed andcan load basic power system information models.

Curtis, Simon J. "Global cities and the transformation of the international system." Thesis, London School of Economics and Political Science (University of London), 2009. http://etheses.lse.ac.uk/2338/.
Full textAbstract:
In recent decades a discourse has emerged around the concept of the 'global city'. This discourse has sought to understand the nature of a set of physical changes to the form of many cities around the world, linking these changes to processes of globalisation. Despite its inspiration for important work in other fields. International Relations has been slow to recognise the implications of the rise of the global city. This thesis argues that the emergence of the global city phenomenon is an important indication of broader transformative tendencies in the contemporary international system. It also argues that International Relations as a discipline offers a unique set of theoretical resources that can help analysts draw out the wider impact of the global city on international politics. In particular, the core concept of the 'international system', when formulated in a historically sensitive fashion, offers insight into the rise and fall of many different institutional forms and structures across time. The modern state system, when viewed from the perspective of la longue duree, may be viewed as a unique historical moment. For much of history, different polities have existed together: empires, city-states, leagues of cities, nomadic peoples. This thesis examines the proposition that the rise of the global city reveals another historic shift in the nature of the international system, and indicates the theoretical resources that may allow us to comprehend such a change. The important relationship between cities and states, it is argued, is now undergoing a historic shift, just as it has at many other points in the past. Understanding the nature of this change illuminates a host of important issues, including transformation in the nature of the state itself, and the renegotiation of the relationship between polities, territorial scale and the global economy in the contemporary world.

Full textAbstract:
A plasmid, pDUB116 Was constructed, containing the Nos-NPT dominant selectable marker for expression in plants which was capable of being mobilised to Agrobacterium tumefaciens and forming cointegrates with pGV3850 and pGV3851. The frequencies of cointegrate formation of these plasmids were determined and the cointegrate structure established by Southern blotting. Inoculation of Kalanchoe diaigremontiana leaves and Nicotiana tabacum stems in vivo showed that pGV3851 is only weakly oncogenic. A fully oncogenic Ti plasmid (pTiGEl) was constructed which was capable of forming cointegrates with pDUB116 and suitable for use in in vivo plant transformation systems. A. tumefaciens GV3101 [pGV3850] was found to be highly resistant to cefotaxime and carbenicillin in plant tissue culture media, preventing its use in in vitro plant transformation proceedures. A. tumefaciens strains were therefore screened for sensitivity to a number of antibiotics, two of which, augmentin and timentin, were found to be inhibitory to the growth of A. tumefaciens but non-inhibitory to callusing, shooting or rooting of N. tabacum in tissue culture.The effect of the SV40 enhancer on the expression of the Nos promoter was investigated by constructing integrating plasmids (pDUBllG derivatives) with the SV40 enhancer 5' and 3'. and in both orientations with respect to the Nos-NPT gene. These plasmids were mobilised to A. tumefaciens and cointegrates with pTiGEl selected, characterised by Southern blotting, and inoculated in vivo onto leaves of K. diaigromentiana. Extracts from the resultant callus tissues were found to contain no detectable NPT activity in all cases. The same constructs were used to transform N. tabacum in vitro by a leaf disc transformation method and callus was selected on hormone free media and kanamycin. The callus induced by the constructs containing the SV40 enhancer showed no significant increase over the control construct, indicating that the SV40 enhancer does not function in these plants. Further improvements to the pBR322-homology mediated Ti vector system were made by constructing a new oncogenic Ti vector. pTiGE2. which has a smaller T-DNA containing a single copy of pBR322. giving a more defined T-DNA which is easier to analyse after cointegrate formation. New T-DNA integrating vectors containing the LacZ insertional inactivation region from pUC18 were constructed giving more unique restriction enzyme sites and making the selection of recombinants easier. A chimaeric CAMV-pea lectin gene was constructed and subcloned into a T-DNA integrating vector. Resultant cointegrates with pGV3850 were characterised and transgenic A'', tabacum plants regenerated. The T-DNA structure and copy number in the transgenic plants were investigated. Expression of the CAMV-pea lectin gene was characterised by northern blotting, western blotting, haemagglutination and ELISA and showed the gene to be expressed constitutively at high levels and the protein to be processed correctly. The subcellular site of lectin deposition in transgenic tobacco root was found to be the vacuole. Plants expressing lectin at high level were screened for resistance to a root-knot nematode and found not to be resistant to infection.

Full textAbstract:
"Multiple U.S. healthcare organizations have been recognized as successful in enterprise-level transformation to create healthcare delivery systems that are safe, effective, patient-centered, timely, efficient and equitable. Many of these organizations have specifically cited the development, deployment and integration of enterprise-level deployment of Lean Management Systems as key to their transformational efforts. Given the intense national interest in improving quality, efficiency and efficacy of healthcare delivery systems, a greater understanding of the strategies utilized by these organizations was required in order to provide an understanding of the mechanisms that drive successful, sustained, enterprise-level transformation. We conducted a realist review of large system transformation utilizing enterprise-level Lean Deployment methods within healthcare organizations. Synthesis and analysis of the results from this review indicate that there are five primary strategies associated with successful healthcare-based Lean deployments: Respect for People; Strategic Alignment; Strategic Deployment; Large Scale System Improvement Efforts; and Small-Scale, Local Improvement Efforts. Additional findings from this review indicate that the applications of the specific mechanisms with these strategies are emergent within multiple transitional phases spanning 6-8 years. To supplement the findings from the realist review, a series of dynamic hypotheses and system dynamics model was created in order to explore how the mechanisms and context interact to drive phase transitions within healthcare-based enterprise-level Lean deployments. The results from this model indicate that no steady state initial conditions exist that support sustained enterprise-level transformation and that the emergent nature of these deployments is necessary to overcome constraints related to the organizational capacity and capability. Additionally, we investigate the design and deployment of enterprise-level Lean programs in order to increase rate of success and decrease deployment cycles. "

Full textAbstract:
In 1994, in response to repeated scandals of political corruption, or of money politics as it was also called, the Japanese Diet passed a comprehensive package of political reform laws. By placing the focus on a change in the election system, this package suggested that money politics was primarily a problem of the incentive structures that the political system provided. This dissertation is based on the premise that political reforms and the debate that produces them are a good indicator of how the Japanese themselves evaluated money politics and what they hoped to change about it. The dissertation shows that both money politics and the political reforms designed to address it have not been a recent phenomenon but have existed more or less continuously for at least 70 years. It analyses the history of three case studies of political reforms that were aimed partly or exclusively at changing money politics: first a political education initiative, second the establishment and amendment of the law controlling political finance and fund-raising, and finally the attempted creation of a law on defining and regulating political parties. These three case studies suggest that reformers saw money politics predominantly as a function of political culture, not of the electoral system. Specifically, they placed this political culture in an evolutionary process of modernisation which sometimes did, sometimes did not resemble Westernisation. They were concerned especially about the role of organisations such as labour unions, companies and political parties as mediators in the relationship between the Japanese voters and the state. Finally, the fact that a changing coalitions of politicians, bureaucrats and independent activists supported the modernisation of the political culture suggests that this interpretation of money politics was widely shared.

Full textAbstract:
Affected by continuous developments and innovations in information and communication technologies, governments have initiated the e-transformation process to adopt the knowledge based economy and to be competitive in global world. Throughout their journey of e-transformation, governments need to learn where they are in order to shift their position to advanced level. To assist governments in their evaluation of e-transformation, this thesis offers a metric system derived from some of the well known e-government evaluation studies. The system proposed is composed of metrics distributed into six main categories: &ldquoTechnology Infrastructure&rdquo
, &ldquo
e-Society&rdquo
, &ldquo
Human Capital&rdquo
, &ldquo
Political and Regulatory Environment&rdquo
, &ldquo
Economy Environment&rdquo
, and &ldquo
Online Services and Applications&rdquo
. Set of metrics to be attached in these categories are determined in terms of widely recognized measures of the tools reviewed. In order to implement the system, 30 countries are analyzed gathering data published by major research institutions. Additionally, this thesis examines Turkey&rsquo
s level on e-transformation from the perspectives of e-government evaluation studies reviewed.

Full textAbstract:
Onion (Allium cepa) bulbs of the New Zealand-bred cultivars 'Pukekohe Longkeeper' and 'Early Longkeeper' produced tumourous growths after inoculation with 25 virulent strains of Agrobactenum tumefaciens, A. rubi and A. rhizogenes. The majority of these tumours produced nopaline, indicating that tumour cells were transformed. Some excised tumours produced roots in sterile culture.
Eight onion genotypes were screened in tissue culture for callus formation, regeneration of plantlets from callus and clonal multiplication by shoot proliferation. All genotypes could be clonally multiplied and four were readily regenerable from callus. A technique for plantlet multiplication, which uses longitudinally-bisected stems of in vitro-germinated onion seedlings as explants, was developed. Onion (‘Pukekohe Longkeeper', 'Southport White Globe', 'Japanese Saporo Yellow' and 'Hikeeper Fl ') protoplasts were isolated and cultured on a range of media. These protoplasts formed new cell walls and sometimes divided, but only first divisions were regularly seen.
Kanamycin, geneticin (G418), hygromycin and chlorsulfuron were evaluated for their use as selective agents in onion transformation experiments. Tissues surveyed for sensitivity to these selective agents included seeds and seedlings on germination and callusing media, established callus on callusing and regeneration media, and shoot cultures on shoot proliferation medium. Hygromycin was shown to be the antibiotic most toxic to tissues of all the surveyed onion cultivars, with effects being obvious
in all tissues after 4-5 weeks of culture on concentrations as low as 20 mgl-1. Kanamycin was shown to be the least toxic of the selection agents surveyed. The kanamycin analogue G418 was considerably more toxic to most onion cultures than kanamycin. However, responses of cultures to G418 were slower than those to hygromycin. The herbicide chlorsulfuron was also shown to be toxic to onion seedlings and shoot cultures.
The ability of Agrobacterium tumefaciens to transfer foreign genes to A. cepa was demonstrated. A single, putatively transformed plantlet (RC1), was regenerated from an onion seedling stem via callus, following co-cultivation of stem explants with Agrobacterium strain LBA4404 harbouring the binary vector pKIWI110. In addition, 41 auxiliary or adventitious shoots which grew directly from basal plates injected in vitro with four strains of A. tumefaciens (each harbouring the binary vectors pKIWI110 or pGA643) exhibited resistance to G418 in culture. The binary vectors used carry the neomycin phosphotransferase II gene (nptII) controlled by the nopaline synthase (nos) promoter. Both RC1 and some of the shoots growing from basal plate explants produced roots when grown on culture media supplemented with G418. Southern analyses showed that fragments of DNA from RC1 and from five of the 41 G418-resistant shoots hybridized to a 1.25 kbp nptII probe. (β- glucuronidase (GUS) activity was detected in over half of the plantlets derived from basal plate tissue injected with A. tumefaciens strains LBA4404 or C58, both of which harboured pKIWI110. Molecular and phenotypic evidence suggested that the putatively transformed plants produced from injected basal plate tissues were
chimeric.

Includes bibliographical references (p. 311-326).
The U.S. government and others around the world have been exploring strategies to respond to climate change for nearly two decades. Consideration of these efforts as well as the 2010 oil spill in the Gulf of Mexico, the 2011 nuclear accident at Fukushima Daichi, and improved shale gas recovery methods are spurring debate on energy policy options. An important focus of this debate is the role of innovation in reducing carbon emissions while also maintaining the affordability of energy supplies. The scale of the required transition to a low-carbon energy system is large. A simple calculation scheme based on the Kaya identity is used to evaluate this transition and to estimate the magnitude of the changes that would be required. The recent performance of the U.S. economy with respect to decarbonization and energy intensity is shown to fall far short of future needs in low-carbon scenarios. The MARKAL model is used to estimate the magnitude of the capital investment required to transform the U.S. electric power sector. A comprehensive treatment of the innovation process must consider not only research and development but also the 'downstream' stages of demonstration, early adoption, and evolutionary post-commercialization improvements. Under greenhouse gas reduction scenarios, investments will be needed in low-carbon technologies when there is still considerable uncertainty and risk associated with their performance, and when they may not be competitive with incumbent energy systems. No less than investments in research and development, these are investments in innovation. A two-stage model of the innovation process is used to estimate the investment needed to bring a new technology to a competitive cost level. The model is used to explore the contributions of early-stage and later-stage investments in innovation, and illustrates the importance of the technological learning process. A case study of innovation in the nuclear energy industry is used to evaluate the effectiveness of alternative policies for driving investment in energy technologies more generally. The case study reveals a pattern of erratic policy that discouraged private investment. The use of technology-push rather than market-pull policy tools is found to have encouraged technology lock-in and discouraged market-driven innovation.

Buckberry, Graham Robert. "An editor and transformation system for a Z animation CASE tool." Thesis, Sheffield Hallam University, 1999. http://shura.shu.ac.uk/19404/.
Full textAbstract:
In order to remain competitive, modem systems developers are increasingly under pressure to produce software solutions to complex problems faster and cheaper, whilst at the same time maintaining a high level of quality in the delivered product. One of the key quality measures is the delivery of a system that meets the customer's requirements. Failure to meet the customer's requirements may engender significant re-design, which in turn will cost money, delay product introduction and may seriously damage the developer's credibility. For these reasons, the problem of developing a precise and unambiguous statement of requirements for a proposed system is perhaps one of the most challenging problems within software engineering today. Formal, model-based specification languages such as the Z notation have been widely adopted within the context of requirements engineering, to provide a vehicle for the development of precise and unambiguous specifications. However, the mathematical foundation upon which these notations are based often makes them unapproachable and difficult to assimilate by a non-specialist reader. The problem then faced is that if the customer cannot understand the semantics of the specification, how can the customer agree that the specification is indeed a true reflection of the requirements for the desired system? Several researchers have proposed that rapid prototyping and animation of specifications can be used to increase the customer's understanding of the formal specification. This is achieved by executing specification components on candidate data and observing that the behaviour is as expected. However this requires that the original formal specification be reliably transformed into a representation capable of being executed within a computer system. To achieve this aim requires the support of computer-based tools able to assist the requirements engineer in capturing, manipulating and transforming the formal specification in an efficient and consistent manner. This thesis describes the research and development of the TranZit tool, which is a Z notation editor, checker and transformation system. TranZit supports the efficient capture and maintenance of Z notation specifications using the Windows Graphical User Interface, supported by a suite of powerful language-driven features. In addition TranZit contains a highly integrated and optimised syntax and type checker, combining traditional compiler design techniques with innovative use of object-oriented data structures and methods, to assist the requirements engineer in ensuring the internal consistency of the captured specification. Most importantly, TranZit contains a novel transformation engine, which is capable of transforming a captured Z specification into an executable representation based on extensions to LISP, suitable for direct execution in an animation environment. This process is supported by an eclectic strategy combining automated transformation with user assistance, to overcome many of the well-documented problems associated with transforming non-executable clauses in formal specifications.

Full textAbstract:
Tjänstefierade IT-system (Software as a Service) växer kraftigt med 50 % per år samtidigt som produktifierade IT-system (Software as a Product) håller på att dö ut. Nya tjänster etableras på ett effektivt sätt för att möta fler behov med färre resurser och leverantören blir delaktig under hela produktens livscykel. Tjänstefierade IT-system förknippas ofta med molntjänster där både lagring och mjukvara erbjuds över nätverk. Dessa tjänster kan erbjudas från datacenter där leverantören sköter driften av IT-infrastruktur. Tjänstesystem säljs främst via två olika intäktsmodeller, användarbaserad intäktsmodell eller uthyrning av mjukvara. Genom att sälja IT-systemet som en tjänst kan leverantören bredda sin kundbas till kunder som inte har det finansiella kapitalet som krävs för att köpa ett IT-system via en mjukvarulicens. Mycket tyder på att en transformation från produkt till tjänst behöver ske för IT-systemleverantörer då efterfrågan inom detta segment ökar. Sveriges näringsliv består till 99 % av små och medelstora företag men det finns ingen tidigare forskning om vilka problem som kan uppkomma under transformationen och vad en liten eller medelstor IT-systemleverantör kan uppnå med ett tjänstesystem. Intresset ligger i att undersöka små och medelstora IT-systemleverantörers erfarenheter kring transformationen och dess hinder och fördelar. Studien har genomfört en teoretisk undersökning för att få en förståelse kring tjänstefierade IT-system och produktifierade IT-system, denna förståelse har legat till grund för den empiriska undersökningen. Eftersom tidigare forskning kring små och medelstora IT-systemleverantörer saknas har studien utgått från empiri för att ta reda på vilka huvudsakliga hinder och fördelar som bör beaktas. Insamling av empiriskt material skedde genom kvalitativa intervjuer och teoretiska underlaget via litteraturstudier. Studien har därefter besvarat vilka huvudsakliga hinder och fördelar en liten eller medelstor IT-systemleverantör bör beakta vid transformation från produktsystem till tjänstesystem.Software as a Service is growing fast by 50 % per year, while Software as a Product is dying. New services are established in an effective way to meet more needs with fewer resources and suppliers become involved during the entire product life cycle. Software as a Service is often associated with cloud services, where both storage and software are offered through network. These services can be offered from data centers where the provider operates IT-infrastructure. Service systems are sold primarily through two different revenue models, Pay as you Go-model or rental-model. By selling IT-system as a service, providers can expand their customer base to customers who do not have the financial power needed to purchase an IT-system software license. A lot suggests that a transformation from product to service is needed for IT-system suppliers, as demand in this segment is increasing. Swedish trade and industry consists of 99 % of small and medium-sized enterprises, but there is no previous research on the problems that may arise during the transformation and what a small or medium-sized IT-system vendor can achieve with a service system. The interest lies in investigating small and medium-sized IT-systems vendors' experiences of the transformation, including its barriers and benefits. The study conducted a theoretical study to get an understanding of Software as a Service and Software as a Product, this understanding has been the basis for the empirical study. Since previous research on small and medium-sized IT-systems suppliers are missing the study has been based on empirical data to find out what the main barriers and benefits that should be considered. Collection of empirical material was done through interviews and theoretical material through literature studies. The study subsequently responded to the main barriers and benefits a small or medium sized IT-system supplier should take into consideration before the transformation from product system to service system.The thesis is written in Swedish.

Full textAbstract:
Schwanniomyces occidentalis (Debaryomyces occidentalis ) is able to grow rapidly with high cell mass on cheap starch as a carbon source, produce strong amylolytic enzymes extracellularly and secrete large proteins without hyper-glycosylation and measurable extracellular proteases. Schw. occidentalis thus has a high potential as, a useful alternative to Saccharomyces cerevisiae in the production of heterologous proteins. However, the molecular study of Schw. occidentalis has been very limited due to the insufficient transformation system and lack of gene expression information.A new transformation system of Schw. occidentalis has been developed. This system was based on vector YEp13 ( LEU2) and a stable leu auxotrophic mutant, Schw. occidentalis DW88, obtained by treating the yeast with 1-methyl-3-nitro-1-nitrosoguanidine. The transformation efficiency of YEp13 by spheroplast-mediating method was 103 transformants/mug DNA. The 2-mum replicon is proposed to be responsible for YEp13 replication in Schw. occidentalis. The YEp13 stability in Schw. occidentalis was low, but it kept its structure in the yeast, suggesting that Schw. occidentalis DW88 does not modify foreign DNA.
After analysis of 14 cloned Schw. occidentalis genes and comparison of associated genes from both Schw. occidentalis and S. cerevisiae, 25 codons were arbitrarily chosen as putative preferred codons for Schw. occidentalis. They are similar to those of S. cerevisiae, except for TTA for leucine, and AAA for lysine. Codon Bias Index (CBI), a criterion to evaluate gene expression, is calculated from preferred codons. A computer program (PCBI) which reads a gene containing introns was developed to quickly calculate CBI.
Schw. occidentalis DWSS should be a good host to produce and secrete heterologous proteins and the putative preferred codons and program PCBI can facilitate molecular study of Schw. occidentalis. (Abstract shortened by UMI.)

A biological reaction diusion model has gained much attention recently. This model is formulated as a system of nonlinear partial dierential equations that contains an unknown function of one dependent variable. How to determine this unknown function is complicated but also useful. This model is considered in this master thesis. The generators of the equivalence groups and invariant solutions are calculated.

Worin bestehen die Bedingungen für einen erfolgreichen Systemtransformationsprozess post-sozialistischer Staaten in demokratisch-marktwirtschaftliche Systeme nach 1990? Die Schwierigkeit einer Untersuchung dieser Frage liegt in der Verlaufs- und Ergebnisoffenheit von Systemtransformationsprozessen, die ihre Prognostizierbarkeit und Gestaltbarkeit einschränkt. Dieser Beitrag stellt hierzu ein methodisches Analysekonzept vor, das aus zwei komplementären Ansätzen aus der evolutorischen Ökonomik besteht: dem Kontingenzansatz und dem Strukturähnlichkeitsansatz. Der Beitrag zeigt, dass erfolgreiche Industrialisierungs- und Wachstumsprozesse einer langen Vorbereitungsphase bedürfen und nicht kurzfristig durch wirtschaftspolitische Maßnahmen bewirkt werden können, wobei technischem Fortschritt und Innovationen eine besondere Bedeutung zukommenWhat are the conditions for successful system transformation into democratic market economies for the post-socialist countries after 1990? The main problem lies in the fact that a system transformation process displays the characteristics of a self-organised economic evolution, which is at least partially open-loop and consequently cannot be predicted and designed perfectly. Our study develops a combined method comprising two approaches compatible with the concepts of evolutionary economics: the contingency approach and the structural similarity approach. Applying this combined method, our analysis shows that successful industrialisation and growth processes require foundations to be laid over a long-term period and that this cannot be substituted by shortterm political intervention. Moreover, a sufficiently high rate of technical progress and innovation is a necessary factor
