The global business is facing the intensive competitive environment. To overcome the competition, most enterprises contentiously try different information systems to strengthen their competition and to extent their businesses. In order to execute the enterprises marketing strategies effectively, business organization applies various software from in-house development to standard package software either made in Taiwan or made in nations. However, while implementing the information system into specific project, this software caused many obstructions in both project time framing design and project cost control. To exam this problem, we found there is no appropriate requirement and package software or tool to manage the system gaps analysis. The main purpose of this thesis is to solve the present package software problem and develop a method to meet the enterprise needs in system difference analysis. We use the Unified Module Language (UML), use case diagram, drawing , activity diagram, use case description and decision table to complete the difference analysis between package software and specific project. Applying this method, the user not only can control the difference between the requirement system and object system precisely, but also build a communication channel among the users, system analysis, and programmers. In addition, the method provides a trend of customized system to succeed the project on line

In new economics such as high-tech, knowledge-driven industries, the competitive game changes frequently and dramatically. Two maxims are widely accepted in these markets: 1. it pays to hit the market first. 2. it pays to have superb technology. These industries face a high change and high speed competitive business environment. Information systems of these firms often have to be modified or created based on imprecise requirements or even conceptual ideals. According to past research literature, precise requirement is one of the key success factors for software development outsourcing. Imprecise requirements indicate uncertain project scope and tend to risk. This research of imprecise requirement software development outsourcing base on Adaptive Software Development and Incomplete Contract theory. A case study is used to analyze below imprecise requirement software outsoucing issues issues in a semiconductor foundry MES project: 1. How to deliver a usable system to achieve project goals from imprecise requirements? 2. How to manage frequent change ascribed to imprecise requirements? 3. How to manage project escalation and cost issue ascribed to imprecise requirement?

The increasing complexity of today’s vehicles gives drivers help with everything from adaptive cruisecontrol to warning lights for low fuel level. But the increasing functionality also increases the risk offailures in the system. To prevent system failures, different safety analytic methods can be used, e.g.,fault trees and/or FMEA-tables. These methods are generally performed manually, and due to thegrowing system size the time spent on safety analysis is growing with increased risk of human errors. If the safety analysis can be automated, lots of time can be saved. This thesis investigates the possibility to generate fault trees from safety requirements as wellas which additional information, if any, that is needed for the generation. Safety requirements are requirements on the systems functionality that has to be fulfilled for the safety of the system to be guaranteed. This means that the safety of the truck, the driver, and the surroundings, depend on thefulfillment of those requirements. The requirements describing the system are structured in a graphusing contract theory. Contract theory defines the dependencies between requirements and connectsthem in a contract structure. To be able to automatically generate the fault tree for a system, information about the systems failure propagation is needed. For this a Bayesian network is used. The network is built from the contract structure and stores the propagation information in all the nodes of the network. This will result in a failure propagation network, which the fault tree generation will be generated from. The failure propagation network is used to see which combinations of faults in the system can violate thesafety goal, i.e., causing one or several hazards. The result of this will be the base of the fault tree. The automatic generation was tested on two different Scania systems, the fuel level displayand the dual circuit steering. Validation was done by comparing the automatically generated trees withmanually generated trees for the two systems showing that the proposed method works as intended. The case studies show that the automated fault tree generation works if the failure propagationinformation exists and can save a lot of time and also minimize the errors made by manuallygenerating the fault trees. The generated fault trees can also be used to validate written requirementsto by analyzing the fault trees created from them.

Threonine has been reported to be the second limiting amino acid in typical equine diets, but its actual requirement has not been determined in horses. The indicator amino acid oxidation (IAAO) method has been successfully used for evaluating amino acid metabolism and requirements in animals and humans. The objective of this research was to use the IAAO method to estimate threonine requirements in mature horses fed two different feed compositions. In the first study, 6 Thoroughbred mares (4 – 16 years old) received each of 6 levels of threonine intake in a high concentrate diet, in a randomly determined order. The experimental diets consisted of concentrate at 0.95% of body weight (BW), and chopped timothy hay at 0.95% of BW, and met or exceeded NRC recommendations for all nutrients. Threonine intakes for the 6 treatments were 45, 56, 67, 79, 90 and 102 mg/kg BW/d and were generated by mixing the two experimental concentrates, containing 2.9 and 14.8 g threonine/kg diet, in different ratios. In the second study, horses received each of 6 levels of threonine intake, 41, 51, 61, 70, 80, and 89 mg/kg BW/d, in a high forage diet, in a randomly determined order. The experimental diet was concentrate at 0.4% of BW, and chopped timothy hay at 1.6% of BW. Study periods for each study were 7-d long and on d 6, blood samples were collected before and 90 min after feeding to measure amino acid concentrations using HPLC. On d 7, horses underwent IAAO procedures, which included a two hour primed, constant intravenous infusion of [13C]sodium bicarbonate to measure total CO2 production and a four hour primed, constant oral administration of [1-13C]phenylalanine to estimate phenylalanine oxidation to CO2. Blood and breath samples were collected to measure blood [13C]phenylalanine, using GC-MS analysis, and breath 13CO2 enrichment, using an infrared isotope analyzer. Experimental data were analyzed using a one-way ANOVA, including orthogonal linear and quadratic contrasts, in the mixed procedures of SAS version 9.3, with treatment as the fixed effect and horse nested in treatment as the random effect. Statistical significance was declared at P0.05). Increasing threonine intake levels in a high forage diet did not affect plasma phenylalanine oxidation by the ANOVA test (P>0.05) but resulted in a linear decrease in phenylalanine oxidation (P=0.04) without a breakpoint by the orthogonal linear contrast. Threonine requirements are still unknown in mature horses fed either high concentrate or high forage diet. The present studies were the first attempt to evaluate threonine requirements in horses by the indicator amino acid oxidation method.

The specification of requirements is one of the most important stages in the development of information system. The correct description is one of the principle goals in preparation of specification of requirements. Well-done specification of information system is a significant support to create software with high functionality, low maintenance and adaptation costs. Filled in document forms play an important role in the analysis of user requirements. This analysis helps to reduce the gap between the user and the system analyst. The methods of form analysis are oriented in creation of an entity relationship scheme. Information system department offering user requirements specification process of functional requirements specification method is similar to natural requirements analysis proceeding. This process begins from specification of users' requirements to incoming and out coming information. This work presents the model and prototype for specification of users' requirements to incoming and out coming information. The model is based on analysis of documents forms given by user. Method is divided into three phases: 1) user incoming and out coming information, 2) data structure analysis, 3) conceptual schema generation. The meta-model repository of requirements specification is presented. The specification process and prototype of specification of incoming and out coming information of user’s requirements are described.

In this thesis we introduce and study an A-optimal minimax design criterion for two-level fractional factorial designs, which can be used to estimate a linear model with main effects and some interactions. The resulting designs are called A-optimal minimax designs, and they are robust against the misspecification of the terms in the linear model. They are also efficient, and often they are the same as A-optimal and D-optimal designs. Various theoretical results about A-optimal minimax designs are derived. A couple of search algorithms including a simulated annealing algorithm are discussed to search for optimal designs, and many interesting examples are presented in the thesis. / Graduate / 0463 / yinyue@uvic.ca

abstract: Service based software (SBS) systems are software systems consisting of services based on the service oriented architecture (SOA). Each service in SBS systems provides partial functionalities and collaborates with other services as workflows to provide the functionalities required by the systems. These services may be developed and/or owned by different entities and physically distributed across the Internet. Compared with traditional software system components which are usually specifically designed for the target systems and bound tightly, the interfaces of services and their communication protocols are standardized, which allow SBS systems to support late binding, provide better interoperability, better flexibility in dynamic business logics, and higher fault tolerance. The development process of SBS systems can be divided to three major phases: 1) SBS specification, 2) service discovery and matching, and 3) service composition and workflow execution. This dissertation focuses on the second phase, and presents a privacy preserving service discovery and ranking approach for multiple user QoS requirements. This approach helps service providers to register services and service users to search services through public, but untrusted service directories with the protection of their privacy against the service directories. The service directories can match the registered services with service requests, but do not learn any information about them. Our approach also enforces access control on services during the matching process, which prevents unauthorized users from discovering services. After the service directories match a set of services that satisfy the service users' functionality requirements, the service discovery approach presented in this dissertation further considers service users' QoS requirements in two steps. First, this approach optimizes services' QoS by making tradeoff among various QoS aspects with users' QoS requirements and preferences. Second, this approach ranks services based on how well they satisfy users' QoS requirements to help service users select the most suitable service to develop their SBSs. / Dissertation/Thesis / Ph.D. Computer Science 2011

O objetivo desta dissertação foi estimar a exigência de lisina (Lis) para frangos de corte machos Cobb x Cobb 500 de 1 a 12 dias de idade (experimento 1), 12 a 28 dias de idade (experimento 2) e 28 a 42 dias de idade (experimento 3). Dietas basais foram formuladas para atingir ou exceder as exigências nutricionais, com exceção da Lis. Cinco níveis de Lis foram suplementados às dietas basais a partir de L-Lis HCl ou sulfato de L-Lis de modo que os níveis variaram de 0,97% a 1,37% de Lis digestível no experimento 1, 0,77% a 1,17% de Lis digestível no experimento 2 e 0,68% a 1,08% de Lis digestível no experimento 3 em incrementos de 0,08%. Os tratamentos foram distribuídos em um delineamento inteiramente casualizado com 8 repetições de 25 aves. Em cada experimento, 2200 aves foram alojadas em 88 unidades experimentais. Nos dias 1 e 12 (experimento 1), 12 e 28 (experimento 2) e 28 e 42 (experimento 3) as aves e a ração foram pesadas para determinar o ganho de peso (GP) e conversão alimentar (CA). No experimento 3, quatro aves por unidade experimental foram abatidas para determinação do rendimento de carcaça e peito. A biodisponibilidade relativa (RBV) das fontes de Lis foi avaliada através de uma regressão multivariada e comparada pelo teste t. A exigência de Lis foi estimada por três modelos de regressão: polinomial quadrática, brokenline linear e broken-line quadrática. A exigência foi representada como 95% do ponto de máxima resposta. Não houve diferença entre a RBV da Lis no sulfato de L-Lis em relação ao L-Lis HCl, portanto ambas as fontes foram utilizadas para estimar as exigências. As exigências encontradas variaram de acordo com o modelo estatístico e a variável analisada. A regressão broken-line quadrática apresentou o melhor ajustamento aos dados de desempenho, enquanto a regressão broken-line linear se ajustou melhor aos dados de rendimento de carcaça e peito. As regressões polinomial quadrática, broken-line linear e broken-line quadrática estimaram, respectivamente, as exigências como 1,190, 1,032 e 1,101% para GP e 1,226, 1,038 e 1,124% para CA no experimento 1; 1,021, 0,900 e 0,961% para GP e 1,064, 0,966 e 1,043% para CA no experimento 2; 0,949, 0,833 e 0,925% para GP, 0,978, 0,851 e 0,960% para CA, 0,933, 0,842 e 0,931% para rendimento de carcaça e 0,952, 0,839 e 0,921% para rendimento de peito no experimento 3. Os resultados demonstraram que as exigências de Lis foram consideravelmente influenciadas pelas diferentes regressões. Portanto, a escolha do modelo estatístico é crítica para a obtenção de estimativas precisas e coerentes. / The objective of this thesis was to estimate lysine (Lys) requirement of male Cobb x Cobb 500 broilers from 1 to 12 days of age (experiment 1), 12 to 28 days of age (experiment 2), and 28 to 42 days of age (experiment 3). Basal diets were formulated to meet or exceed recommendations, except for Lys. Five graded levels of Lys were supplemented from L-Lys HCl or L-Lys sulfate to the basal diets. Dietary treatments ranged from 0.97% to 1.37% digestible Lys in experiment 1, 0.77% to 1.17% digestible Lys in experiment 2, and 0.68% to 1.08% digestible Lys in experiment 3 in 0.08% increments. Treatments were distributed in a completely randomized design with 8 repetitions of 25 birds each. A total of 2,200 birds per experiment were placed in 88 experimental units. At 1 and 12 days (experiment 1), 12 and 28 days (experiment 2), and 28 and 42 days (experiment 3), birds and feed were weighed to determine body weight gain (BWG) and feed conversion ratio (FCR). In experiment 3, four birds per experimental unit were processed for carcass and breast meat yield evaluation. Relative bioavailability (RBV) of Lys sources was assessed by a multivariate regression and compared by a t-test. Lysine requirement was estimated using three regression models: quadratic polynomial, linear broken-line, and quadratic broken-line. Requirements were represented as 95% of the asymptote. No difference was observed in Lys RBV in L-Lys sulfate compared to L-Lys HCl, thus both sources were used to estimate requirements. Requirement estimates varied according to statistic model and analyzed variable. Quadratic broken-line model presented the best fit to performance data (BWG and FCR), whereas linear broken-line model fitted better to carcass and breast meat yield data. Quadratic polynomial, linear broken-line, and quadratic brokenline estimates were, respectively, 1.190, 1.032, and 1.101% for BW gain and 1.226, 1.038, and 1.124% for FCR in experiment 1; 1.021, 0.900, and 0.961% for BW gain and as 1.064, 0.966, and 1.043% for FCR in experiment 2; and 0.949, 0.833, 0.925% for BW gain, 0.978, 0.851, and 0.960% for FCR, 0.933, 0.842, and 0.931% for carcass yield, and 0.952, 0.839, and 0.921% for breast meat yield in experiment 3. Results demonstrate that Lys requirements were considerably influenced by different regression models. Therefore, the choice of statistical model is crucial to obtain precise, coherent estimates.

O sistema é conduzido em cultivo protegido, no qual o manejo correto de irrigação é fator essencial para manter a qualidade da produção. O objetivo do estudo foi expor detalhes da construção e calibração de três lisímetros de pesagem de baixo custo e utilizá-los para determinar evapotranspiração de cultura (ETc) e coeficiente de cultura (Kc) de MPB de três cultivares de cana-de-açúcar (CTC9005HP, RB966928 e SP87365), aliados à análise de crescimento, para manejo de irrigação em cultivo protegido. Três lisímetros de pesagem foram construídos especificamente para MPB em casa de vegetação da Usina São Martinho (São Martinho S/A), cada qual com área de 0,6909 m2 (1179 mm x 586 mm), profundidade de 400 mm e apoiados sobre 3 células de carga. A calibração dos lisímetros demonstrou precisão e acurácia na detecção de variações de massa equivalente em torno de 0,1 mm pelos equipamentos e magnitude de histerese que não comprometeu as avaliações de evapotranspiração. O custo de equipamentos foi baixo, exceto o sistema de aquisição de dados. A determinação de ETc e cálculo de ETo pelo método FAO-56 possibilitaram inferir valores de Kc ao longo do ciclo de produção. O consumo hídrico, determinado pela ETc, variou de 3,0 a 6,9 mm d-1 na CTC9005HP, 3,1 a 6,8 mm d-1 na RB966928 e 2,9 a 6,6 mm d-1 na SP87365. Kc teve elevação de 1,00 a 1,46 na CTC9005HP, 1,02 a 1,53 na RB966928 e 1,02 a 1,49 na SP87365. A poda das folhas aos 37 dias após a transferência reduziu ETc e, consequentemente, Kc dos tratamentos. Altura de colmos foi superior em SP87365 e CTC9005HP e diâmetro de colmos em RB966928. SP87365 foi superior à CTC9005HP nas avaliações foliares. Massas frescas e secas de colmos e total não diferiram entre cultivares. Épocas de avaliação apresentaram diferenças nas avaliações, confirmando o crescimento das plantas. Portanto, ETc e Kc de MPB foram determinadas por lisímetros de precisão de baixo custo, aliados à análise de crescimento, para manejo de irrigação de MPB em cultivo protegido. / The pre-sprouted sugarcane plantlets production system (PSS) is an innovative method to enhance crop multiplication rates. This system is greenhouse-grown, where correct irrigation management is essential to maintain the production quality. The purpose of this study was to detail construction and calibration of three low-cost weighing lysimeters and to use them to determine crop evapotranspiration (ETc) and crop coefficient (Kc), allied to growth analysis, of three sugarcane cultivars (CTC9005HP, RB966928 and SP87365), for irrigation management of greenhouse grown PSS. Three specific PSS weighing lysimeters were built in a greenhouse at São Martinho Mill (São Martinho S/A) and covered 0.6909 m2 (1179 mm x 586 mm) with 400 mm depth supported by 3 load cells. The lysimeters calibration showed precision and accuracy detection of equivalent-mass variations around 0.1 mm and hysteresis that did not compromise evapotranspiration measurements. Low cost materials were used in this study, excluding acquisition data system. Determined ETc and calculated FAO-56 ETo resulted in production cycle Kc values. Water requirement, determined by ETc, ranged from 3.0 to 6.9 mm d-1 in CTC9005HP, 3.1 to 6.8 mm d-1 in RB966928 and 2.9 to 6.6 mm d-1 in SP87365. Kc increased from 1.00 to 1.46 in CTC9005HP, 1.02 to 1.53 in RB966928 and 1.02 to 1.49 in SP87365. Treatments leaves pruning at 37 days after transference to greenhouse decreased ETc and, consequently, Kc. Stalk height was higher in SP87365 and CTC9005HP and stalk diameter in RB966928. SP87365 was superior to CTC9005HP in leaf evaluations. Total and stalk fresh and dry masses did not differ between cultivars. Evaluation periods presented difference in evaluations, confirming plants growth. Therefore, ETc and Kc were successfully determined by built precision low-cost lysimeters, allied to growth analysis, for PSS irrigation management in greenhouse grown.
