本研究以Ohlson (1995) model為發展基礎，並將盈餘定義為（１）剩餘淨利及（２）盈餘水準，分別就此二種不同定義下的盈餘，以年度盈餘時間序列來測試其是否符合線性資訊動態假設，及針對各模式對股權價值估計與預測之結果做比較，探討何種評價方法或模式對於估計真實價值、解釋價格及預測報酬之效果較佳。 研究結果發現，我國上市公司之剩餘淨利及盈餘水準時間序列皆符合線性資訊動態假說。剩餘淨利線性資訊動態模型較能正確預估次一期的盈餘。相較於單獨以帳面價值來估計股價，考慮線性資訊動態模型所建立之各評價模型所預測之估計股價皆未能正確預測權益價值及解釋權益價值之波動。在投資策略方面，因剩餘淨利模型之投資績效最為穩定，在該模型之投資策略下，V/P比率愈低（高）之投資組合獲得之平均股票報酬愈低（高），代表股價愈是被低估的投資組合可賺取更多之投資報酬，這說明剩餘淨利模型預測次期投資報酬之能力最佳，投資人可以其做為建立投資策略的參考。 / Based on Ohlson (1995) model, this study specifies earnings variables as both residual income and earnings levels to test the linear information dynamic (LID) models per se and the ability of competing valuation models to value the contemporaneous stock prices. A comparison of future stock return predicting capability of competing models is also conducted. By using both residual income time series and earnings levels time series for examining the issue on the firms listed on the Taiwan Stock Exchange (TSE), the empirical results support Ohlson’s information dynamics. However, when estimated as a time series, the linear information models using either residual income or earnings levels variables provide value estimates no better than book value does alone. From the investment strategy aspect, the superior predictive ability of the residual income valuation model with respect to future stock returns demonstrates that high (low) V/P ratios gets high (low) investment returns. It implies that the underpriced portfolio makes high investment returns. Accordingly, the residual income valuation is good for estimating returns on the following year and is therefore a valuable investment reference..

In this paper we estimate space-time impacts of the embeddedness in R&D networks on regional knowledge production by means of a dynamic spatial panel data model with non-linear effects for a set of 229 European NUTS-2 regions in the period 1999-2009. Embeddedness refers to the positioning in networks where nodes represent regions that are linked by joint R&D endeavours in European Framework Programmes. We observe positive immediate impacts on regional knowledge production arising from increased embeddedness in EU funded R&D networks, in particular for regions with lower own knowledge endowments. However, long-term impacts of R&D network embeddedness are comparatively small.(authors' abstract) / Series: Department of Economics Working Paper Series

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.

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.

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.

隨著地籍管理工作在廣度深度上的增加，使得地籍、土地利用等歷史資料的查詢與檢索日益頻繁，但現階段地籍管理系統之建置方法對於歷史資料查詢之效率較差。本文在探討含時間維度資料庫之建置方法，並利用異動時間與異動註記等欄位及異動紀錄表之建立，令目前地籍管理系統可達到以時間維度，或指定地號，進行地籍資料查詢與檢索。 / The more cadastral management is developed, the more historic data query of cadastre and land use are important. The primary purpose of this study is concentrated on the recoveries of parcel linage and areas on any time profile. The targets of this research are placed on design of spatio-temporal data model, and the analysis of efficiency of data recovery and query.

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.

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.

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
