Round-trip engineering concept for hierarchical UML models in AUTOSAR-based safety projects

Pathni, Charu 09 November 2015 (has links) (PDF)
Product development process begins at a very abstract level of understanding the requirements. The data needs to be passed on the next phase of development. This happens after every stage for further development and finally a product is made. This thesis deals with the data exchange process of software development process in specific. The problem lies in handling of data in terms of redundancy and versions of the data to be handled. Also, once data passed on to next stage, the ability to exchange it in reveres order is not existent in evident forms. The results found during this thesis discusses the solutions for the problem by getting all the data at same level, in terms of its format. Having the concept ready, provides an opportunity to use this data based on our requirements. In this research, the problem of data consistency, data verification is dealt with. This data is used during the development and data merging from various sources. The concept that is formulated can be expanded to a wide variety of applications with respect to development process. If the process involves exchange of data - scalability and generalization are the main foundation concepts that are contained within the concept.

Programinės įrangos palaikymo sistema. Objektiškai orientuoto duomenų modelio tyrimas / Software Support System. Object oriented data model research

Mačiulis, Paulius 16 August 2007 (has links)
Sukurti programinę įrangą dažnai skiriama per mažai laiko, programuotojai priversti skubėti. Dažnai nelieka laiko išsamiems programos testams atlikti, o produktas jau atiduodamas klientui. Programinę įrangą įsigiję vartotojai nori, kad rasti defektai būtų kuo greičiau pašalinti. Programinės įrangos kūrėjai suinteresuoti turėti patikimą grįžtamąjį ryšį su vartotojais ir kaupti defektų istoriją, kad vėliau iš sukauptų duomenų galėtų atlikti statistinius tyrimus. Projekto tikslas - realizuoti universalią programinės įrangos palaikymo sistemą (angl. software support system), pritaikytą tiek programinės įrangos kūrėjams, tiek galutiniams programinės įrangos pirkėjams. Panaudoti naujausias projektavimo ir programavimo technologijas, taip užtikrinant efektyvų tolimesnį sistemos palaikymą. Išanalizuoti ir panaudoti objektiškai orientuotą duomenų modelį, palyginti jį su standartiniais duomenų valdymo modeliais. Ištirti laikines modelių charakteristikas. / Software projects must meet development time constrains and continuously changing requirements. Software developers work under pressure to meet task deadlines and there is often no time left for exhausting software testing. Errors happen. It's very important to find them in proper time, collect and make bug reports. Also corrected errors and bugs can't be forgotten. After shipping beta and final versions of the software, developers miss feedback from the users. To accumulate information about software errors can be a problematic task. Work purpose is to create universal bug reporting system, adapted to software developers and end users. This system is accessible via local network and internet. Application developed using modern OOP technologies and .NET 2.0 Framework. Finally, the object oriented data model research was accomplished. This data model was compared with standard data models. A performance and features of data models was tested. The critical conclusions were accepted.

以業務流程角度建立資料倉儲模式之研究 - 以某事業單位為例

嚴千凱, Yen , Chien-Kai Unknown Date (has links)
政府事業單位重要的任務之一,在於擬定相關管理與營運的政策,因此有關於營運面的相關資訊,就成為重要的決策依據。除此之外來自民意單位質詢,彈性相當大,範圍包含了整個事業業務,因此對於決策資訊需求,往往都是包羅萬象千變萬化的,因此如何快速且正確地取得營運資訊,便成為各單位一嚴峻的考驗,而目前以報表為基礎的營運決策模式,已經漸漸無法符合變動性日增的決策需求,而資料倉儲與多維度模型的設計,正可符合快速變動的決策資訊需求。 本論文將透過對於個案組織的深入質化訪談,進一步建立個案組織的業務流程,並且透過對於個案組織業務內容的深入瞭解,對於其政策制訂之相關決策點、參考資訊、資訊流做詳細的分析,以便針對對決策資訊的來源與性質,找出相對應的屬性、維度與事實。如此一來,便可發現資料倉儲的設計,必須以流程模型為基礎,並且透過模型的指引,設計適合用戶業務內容的資料倉儲與資料模型,並且為未來組織轉型時的配適,提供最大的彈性。

To verify these relationships, two different econometric methodologies were used: The Multiple Linear Regression and the Panel Data Model. The data collected are from the companies listed in the Stock Exchange Index of São Paulo - iBovespa. The results obtained by both methods were not the same as in theory, because some of the determinants did not show the expected behavior, and also were not statistically significant. The main contribution of this study is the use of Panel Data methodology to obtain the results. / Esse trabalho tem como objetivo investigar a relação entre três múltiplos específicos (Preço/Lucro, Preço/Valor Patrimonial e Preço/Vendas) e seus determinantes (crescimento, payout ratio, risco, ROE e margem líquida), de acordo com a teoria apresentada por Aswath Damodaran. Para verificar essas relações, foram utilizadas duas metodologias econométricas distintas: A Regressão Linear Múltipla e o Modelo de Dados em Painel. Os dados coletados são referentes às empresas listadas no índice de ações da Bolsa de Valores de São Paulo – iBOVESPA. Os resultados apurados por ambos os métodos não foram os mesmos verificados na teoria, pois alguns dos determinantes não apresentaram o comportamento esperado, e também não foram estatisticamente significantes. A principal contribuição desse trabalho é a utilização da metodologia de Dados em Painel para obter os resultados.

Analysis of transfer of value added tax - vaf in transfers to the icms municipalities in cearà / AnÃlise do repasse do valor adicionado fiscal â vaf nas transferÃncias do icms aos municÃpios cearenses

Ãngelo Fernandes Moreno dos Santos 27 February 2012 (has links)
nÃo hà / This study aims to analyze the transfer of the Value Added Tax (VAF) in the transfer of resources from ICMS to municipalities in Cearà stipulates as the Federal Constitution of 1988 and the Supplementary Law No. 63 of 1990. The research will include the period from 2003 to 2010 of all 184 municipalities of Cearà and used in data analysis, the econometric model for panel data. With this model, we sought to determine how the independent variables Bolsa Familia, FPM, GDP, Complementary Law No. 86/97 and CIDE influence the dependent variable (VAF). The results show that the explanatory variables in a positive impact in increasing the transfer of the VAF for the municipalities of CearÃ. The variable that was most significant was the Complementary Law No. 86/97, created with the intent to waive the collection of the tax ICMS products and services for export, so the VAF provides an increase in the transfer to the municipalities about 7.47% when there is an increase of its exports. / Este estudo tem como objetivo analisar o repasse do Valor Adicionado Fiscal (VAF) na transferÃncia dos recursos do ICMS devido aos municÃpios cearenses conforme preceitua a ConstituiÃÃo Federal de 1988 e a Lei Complementar n 63 de 1990. A pesquisa compreenderà o perÃodo de 2003 a 2010 de todos os 184 municÃpios cearenses e utilizou-se, na anÃlise dos dados, o modelo economÃtrico de dados em painel. Com esse modelo, buscou-se verificar como as variÃveis independentes Bolsa FamÃlia, FPM, PIB, Lei Complementar n 86/97 e CIDE influenciam na variÃvel dependente (VAF). Os resultados demonstram que as variÃveis explicativas impactam de forma positiva no aumento do repasse do VAF para os municÃpios cearenses. A variÃvel que se apresentou mais significativa foi a Lei Complementar n 86/97, criada com o intuito de isentar da cobranÃa do tributo ICMS os produtos e serviÃos destinados à exportaÃÃo, portanto, o VAF proporciona um aumento no repasse para os municÃpios de cerca de 7,47% quando hà um aumento de suas exportaÃÃes.

No. of bitstreams: 1 Lacerda_FabrizzioCabralde_M.pdf: 1883686 bytes, checksum: c6ae7f1ec9d40594dd97e011ec07e59b (MD5) Previous issue date: 2007 / Resumo: A gerência de redes é formada por cinco áreas funcionais: Falha, Configuração, Contabilidade, Desempenho e Segurança. A área de configuração é responsável pela operação e manutenção da rede, acompanhando as mudanças de configuração realizadas em cada dispositivo da rede. As principais ferramentas de gerência disponíveis, CLI e SNMP, não atendem aos requisitos de configurações das redes atuais. Novas tecnologias Web estão se tornando comuns na gerência de redes, com destaque para o uso da linguagem XML e do protocolo HTTP. Com o objetivo de aplicar estas novas tecnologias na configuração de redes foi definido, no âmbito do IETF, um novo protocolo de gerência de configuração denominado NETCONF. Este trabalho faz um estudo do protocolo NETCONF procurando destacar as suas vantagens e limitações. Este trabalho propõe, também, uma arquitetura de implementação para o NETCONF baseada no protocolo de transporte SOAP sobre HTTP, ou sobre HTTPs. Com o objetivo de validar a arquitetura, apresentamos a implementação de um protótipo totalmente aderente à proposta NETCONF para o qual foi especificado um modelo de dados para configuração de VLANs de switches de fabricantes diferentes / Abstract: Network management is formed by five functional areas: Failure, Configuration, Accounting, Performance and Security. The configuration area is responsible for the network¿s operation and maintenance, following the configuration changes done in each network¿s device. The main management tools available, CLI and SNMP, do not take care of the configuration requirements of current networks. New Web technologies are becoming widespread in network management, with prominence of XML language and HTTP protocol. A new protocol of configuration management named NETCONF has been defined, in the scope of the IETF, in order to apply these new technologies for configuration of networks. This work studies the NETCONF protocol aiming to highlight its advantages and limitations. This work also proposes an architecture of implementation for the NETCONF based on the transport protocol SOAP over HTTP, or HTTPs. Aiming to validate such architecture, we present the implementation of a prototype fully adherent to the NETCONF proposal, for which it has specified a model of data for configuration of VLANs of switches from different manufacturers / Mestrado / Engenharia de Computação / Mestre em Engenharia Elétrica

No. of bitstreams: 1 rosaliviagoncalvesmontenegro.pdf: 1198338 bytes, checksum: d89102c7afac67d168fb89d581f5cd22 (MD5) Previous issue date: 2008-12-18 / O objetivo principal do trabalho é investigar a influência de externalidades de diversificação e de especialização sobre a atividade inovadora de microrregiões de estado de São Paulo, no período compreendido entre 1996-2003. Além disso, outros fatores determinantes da inovação são também considerados, como a capacidade de realização de P&D, o nível de escolaridade e a defasagem temporal da inovação. As patentes per capita são usadas na pesquisa como proxy para a avaliação da atividade inovadora, ou seja, medem a capacidade tecnológica da microrregião. A base de dados consiste na utilização de microdados provenientes do Instituto Brasileiro de Geografia e Estatística (IBGE) e dos dados de depósitos de patentes do Instituto Nacional de Propriedade Industrial (INPI). A metodologia aplicada aborda a Análise Exploratória de Dados Espaciais (AEDE) e modelos de regressão espacial com dados em painel. Ambas as técnicas permitiram um acompanhamento espacial e temporal do progresso do sistema regional de inovação em São Paulo. Os resultados revelaram que a especialização produtiva das microrregiões é fator determinante para seu desempenho inovador. Alguns efeitos também se mostram importantes como a escolaridade, as inovações realizadas no período anterior, os transbordamentos de conhecimentos e, em menor grau, as externalidades de diversificação. / The aim of the present work is to assess the extent to which the degree of specialization or diversification externalities may affect the innovative performance in a particular microregion. Additionally, the influence of other regional factors on the innovative output is examined, such as regional R&D capacity, schooling of local population and the innovative tradition of the microregion. The analysis is based on a database of 63 microregions of the state of São Paulo from 1996 to 2003 that was merged by micro-data mainly from Yearly Industrial Survey and Brazilian Patent Office. These data were analyzed by means of Exploratory Analysis of Spatial Data and panel data regression models with spatial dependence. Both techniques reveal the spatial and temporal evolution of the regional innovation system of the state of São Paulo. The main result shows that microregion’s innovative performance seems to be affected mainly by the specialization externalities rather than diversification externalities. Other results emphasize the positive influence played by the schooling of local population, the technological knwoledge spillovers, and the innovative tradition of the microregion on its innovative output.

Statistical models for an MTPL portfolio / Statistical models for an MTPL portfolio

Pirozhkova, Daria January 2017 (has links)
In this thesis, we consider several statistical techniques applicable to claim frequency models of an MTPL portfolio with a focus on overdispersion. The practical part of the work is focused on the application and comparison of the models on real data represented by an MTPL portfolio. The comparison is presented by the results of goodness-of-fit measures. Furthermore, the predictive power of selected models is tested for the given dataset, using the simulation method. Hence, this thesis provides a combination of the analysis of goodness-of-fit results and the predictive power of the models.

Contribution à la définition d’un modèle d’ingénierie concourante pour la mise en oeuvre des projets d’infrastructures linéaires urbaines : prise en compte des interactions entre enjeux, acteurs, échelles et objets / Contribution to the definition of a concurrent engineering model for the implementation on urban linear infrastructure projects : taking into account the interactions between issues, stakeholders, scales and objects

Tolmer, Charles-Edouard 07 November 2016 (has links)
Le BIM est actuellement en pleine explosion. Il s'appuie sur la progression des outils informatiques. Toutefois, la gestion de l'information au sein d'un projet d'infrastructure nécessite également l'utilisation de méthodologies et de concepts spécifiques comme les notions de « niveau de détail », de « niveau de développement » ou de « niveau d'abstraction ». Ils servent à décrire l'information pertinente à échanger entre acteurs, selon des objectifs de modélisation, en vue de répondre à des exigences identifiées. Dans le contexte spécifique des projets d'infrastructures, ces outils ne sont mal définis, insuffisants et amènent parfois à des modélisations contradictoires.Dans une optique de progression vers une conception en ingénierie concourante, notre travail de recherche apporte une contribution en deux parties. En se basant sur les principes de l'ingénierie système, la première partie consiste en une méthodologie d'identification des exigences à satisfaire et de l'information pertinente pour y répondre et contrôler cette réponse. La seconde partie décrit le modèle conceptuel de données. Il traite de la structuration des objets qui modélisent le projet en lien avec la structuration des exigences. Cette proposition s'accompagne d'une redéfinition de plusieurs types de niveaux existants (de détail, de développement, d'information, d'abstraction, etc.). Ces éléments sont éprouvés sur un projet d'autoroute en milieu urbain.Les échanges d'informations sont au cœur du BIM. Leur précision ainsi que la qualité des informations échangées participent à la réussite tant technique que managériale du projet.Notre proposition méthodologique permet de faire évoluer les pratiques et le regard que le secteur de la construction porte sur l'information qu'il crée. Elle participe également à la numérisation du secteur de la construction / However, the information management within an infrastructure project (road, rail, airport and other civil engineering works) also requires the use of specific methodologies and concepts like the concepts of ”level of detail” , ”level of development” or ”level of abstraction”. They are used to describe the relevant information that have to be exchanged between stakeholders, according to the modeling objectives in order to meet the project requirements. In the specific context of infrastructure projects, these tools are poorly defined, insufficient and sometimes bring to contradictory models.With a view to progress towards concurrent engineering design, our research is a contribution in two parts. Based on the principles of systems engineering, the first part is about to provide a methodology for requirements and relevant information identification to respond and control this response. The second part describes the project conceptual data model : it deals with the structure of the objects that model in connection with the requirements identification. This proposal is accompanied by a redefinition of several types of existing levels (detail, development, information, abstraction, etc.). These inputs are tested on a project of urban freeway in an industrial context.The exchange of information is at the center of BIM. The accuracy and quality of exchanged information participate in both technical and managerial project success. Our proposed methodology allows to change practices and the vision that the construction sector looks forward to the information it creates. It also participates in the digitalization of the construction sector
