The aim of the work is to analyze, design and implement project planning web application, integrated on SAP NetWeaver Portal platform. Although the requirements are based on the needs of Mibcon a.s. company, the resulting application solves the problematics of project management in general. Technologies, used during the implementation are Adobe Flex (user interface), Java (server integration layer) and Oracle database (backend). The reader is introduced to various aspects of portal application development. Representative technical details, used during implementation, are presented here as well.

A dynamic hierarchical web-based portal was created to house a suite of web-based supply chain management applications. The portal was designed in a hierarchical manner to match the structure of large companies. Administrators of the the portal have the ability to form the portal in such a way to mimic the existing structure of their company. Access rights to the applications in the portal may be granted or denied per division and the users of the portal are placed in these divisions based on their duty in the company. In addition, users are granted roles which dictate their ability to modify how the portal behaves. This thesis covers the client-side portion of the portal which includes the user interface and several client/server interfaces. The client-side was built with the Adobe Flex SDK and the Flash Builder 4 IDE, which connects to a ASP.NET MVC 3 back end and a MSSQL database. The code was internationalized to be able to plug in a localized language resource file. Unit tests were written with FlexUnit to test the code before deployment.

A novel approach to miniaturizing an 802.11b WLAN card using folded-flex ultra-thin substrates is presented. A 73 percent reduction in size was realized using hybrid circuits on FR4 and polyimide. There is even more potential for further reduction if more copper layers are used. The miniaturized 802.11b WLAN cards were used to design 802.11b wireless sensor nodes. A research test-bed was setup to study how 802.11b networked sensor nodes could operate in the field. There are many applications for such sensor networks like habitat monitoring, object tracking, seismic detection, military surveillance, or fire detection to name a few. This investigation focuses on the requirements, design, and performance of a miniaturized 802.11b wireless LAN sensor node that is reliable, can be deployed in large-scale, and has the endurance long-lived for surveillance applications. An aperture coupled microstrip antenna is investigated for 2.44 GHz wireless local area networks (WLAN) which has the advantages of being low-profile and compact. The most important parameters for antenna optimization have been determined through extensive simulation using Ansoft's HFSS and experimental verification. As a result, an omnidirectional antenna with a size of 36.2 mm x 32 mm x 4.75 mm has been realized using Rogers 5880 duroid (permittivity = 2.20 ; loss tangent = 0.0004) with 4.4 dBi of gain, > 80 MHz, and a return loss > -32 dB. These types of performance characteristics make the antenna highly desirable for both 802.11b and Bluetooth applications.

Top Tensioned Riser (TTR) and Steel Catenary Riser (SCR) are often used in a floating oil/gas production system deployed in deep water for oil transport. This study focuses on the improvements to the existing numerical code, known as CABLE3D, to allow for static and dynamic simulation of a TTR connected to a floating structure through a tensioner system or buoyancy can, and a SCR connected to a floating structure through a flex joint. A tensioner system usually consists of three to four cylindrical tensioners. Although the stiffness of individual tensioner is assumed to be linear, the resultant stiffness of a tensioner system may be nonlinear. The vertical friction at a riser guide is neglected assuming a roller is installed there. Near the water surface, a TTR is forced to move due to the motion of the upper deck of a floating structure as well as related riser guides. Using the up-dated CABLE3D, the dynamic simulation of TTRs will be made to reveal their motion, tension, and bending moment, which is important for the design. A flex joint is approximated by a rotational spring with linear stiffness, which is used as a connection between a SCR and a floating structure or a connection between a TTR and the sea floor. The improved CABLE3D will be integrated into a numerical code, known as COUPLE, for the simulation of the dynamic interaction among the hull of a floating structure, such as SPAR or TLP, its mooring system and riser system under the impact of wind, current and waves. To demonstrate the application of the improved CABLE3D and its integration with COUPLE, the related simulation is made for ‘Constitution’ SPAR under the met-ocean conditions of hurricane ‘Ike’. The mooring system of the Spar consists of nine mooring lines and the riser system consists of six TTRs and two SCRs.

Fundamenta-se, inicialmente, em pesquisa bibliogr?fica, visando ampliar a compreens?o sobre os edif?cios de uso misto, o conforto ambiental e a flexibilidade aplicada ? arquitetura, principalmente a partir dos trabalhos de Kronenburg (2007) e Jorge (2012). O conceito de flexibilidade ? tratado como uma resposta poss?vel ?s demandas funcionais e formais pretendidas para o projeto. Nesse sentido, ensejando uma analogia com a c?lula vegetal, a cria??o de uma ?segunda pele? com estruturas manej?veis funciona como um filtro, solucionando quest?es pertinentes ? promo??o do conforto ambiental ? como sombreamento e permeabilidade da ventila??o ? e tamb?m quanto ? privacidade. Do ponto de vista formal, essa solu??o confere tamb?m ao edif?cio caracter?sticas como dinamismo e flexibilidade. A pesquisa emp?rica baseou-se na an?lise dos condicionantes do terreno ? aspectos f?sico/ambientais e prescri??es urban?sticas/legais ? e estudos de refer?ncias diretos e indiretos, que subsidiaram a defini??o da programa??o, do partido arquitet?nico e das estrat?gias de conforto ambiental. A proposta arquitet?nica ? apresentada em n?vel de anteprojeto, acompanhada de um memorial que cont?m a descri??o e justificativa das solu??es projetuais adotadas, especialmente quanto ao emprego de envolt?rias flex?veis na edifica??o. / This dissertation describes the design and development of an architecture project for a mixed use building (multifamily and commercial residential), with application of bioclimatic principles of environmental comfort for the city of Natal / RN and emphasis on the elaboration of flexible enclosures. It is based, initially, on bibliographical research, aiming to broaden the understanding about mixed-use buildings, environmental comfort and flexibility applied to architecture, mainly from Kronenburg (2007) and Jorge (2012). The concept of flexibility is treated as a possible response to the functional and formal demands intended for the project. In this sense, by creating an analogy with the vegetable cell, the creation of a "second skin" with manageable structures functions as a filter, solving issues pertinent to promoting environmental comfort - such as shading and permeability of ventilation - as well as privacy. From the formal point of view, this solution also gives the building characteristics such as dynamism and flexibility. The empirical research was based on the analysis of the conditions of the site - physical / environmental aspects and urban prescriptions - and studies of direct and indirect references, which subsidized the definition of programming, the architectural party and environmental comfort strategies. The architectural proposal is accompanied by a memorial that contains the description and justification of the design solutions adopted, especially regarding the use of flexible envelopes in the building.

This report is a part of a thesis work at the division of Fluid and Mechatronic Systems(Flumes) at Linkoping University. The aim of this thesis is to build a robust, advanced, simple, easy to maintain, easy to develop and user-friendly program for the general aviation aircraft conceptual design. The program name is FLEX (FlumesExcel). The program was developed based on the most famous references in this eld such as Raymer [1], Gudmundsson [2] and Torenbeek [3]. Dierent methods and equations were evaluated to choose the best. In case there is no way to evaluate the methods, they were all implemented and the user has the ability to choose the desired one. Microsoft Excel was chosen to build the program and Excel VBA was used to build macros and functions in order to serve the objectives of the program. This report explains the used methods, the implementation way, and the program arrangement. It also shows how the results are presented in the program and provides the user with notes about the program using and its limits. The author supposes that the reader is familiar with the basic aerodynamic and aircraft design knowledge and nomenclatures. In order to not extend the report, some methods and theories are referred to the references without deep explanation. In case the used equations were derived by the author, they are explained in detail.

Quando dois ou mais mercados, anteriormente separados, começam a apresentar certa convergência de preços, diz-se que eles estão integrados. Geralmente, os pesquisadores têm objetivado o estudo da integração entre mercados externos e internos (integração espacial) ou entre os diferentes elos de uma cadeia produtiva (integração vertical), mas de um único produto. Após uma importante mudança na tecnologia, concretizada através do lançamento dos motores flex-fuel no Brasil, a presente pesquisa teve por desafio analisar a existência de integração entre os mercados da gasolina e do etanol, dita como "integração de mercados por substituição". Para tal fim, e depois de filtradas as séries de preços mediante os testes de estacionariedade (Dickey-Fuller Aumentado e Phillips-Perron), foi feito uso de modelos de transmissão de preços, mais especificamente os testes de Cointegração, o do Mecanismo de Correção de Erro (MCE) e o da Causalidade. No período em análise (de março de 2003 até julho de 2008), foi constatada a presença de cointegração entre os dois mercados. Também foi observado que um incremento de 1% no preço da gasolina é responsável por um incremento de 2,74% no preço do etanol. Ainda que tenha sido pequeno o parâmetro do Mecanismo de Correção de Erro obtido, ele indica que é possível relacionar o comportamento de curto com o de longo prazo, nas séries analisadas. Dos resultados obtidos, pode-se concluir que os mercados do etanol e da gasolina estão integrados a longo prazo, onde variações no preço da gasolina causam variações no do etanol (GRANGER, 1969). / When two or more markets, previously separated, start showing a price convergence, it is possible to say that they are integrated. Usually, the researchers have focused the integration study between external and internal market (spatial integration) or between the different links of a productive chain (vertical integration), but just of an unique product. After an important technological change, materialized in the releasing of flex-fuel motors in Brazil, this work had as a challenge analyze the existence of the integration between the gasoline and ethanol markets, referred as "integration of substitution markets". Therefore, after filtering the prices series through stationary tests (Augmented Dickey-Fuller and Phillips-Perron), it was made the use of price transmission models, specifically the cointegration tests, and the Error Correction Mechanism (ECM) and the causality. In the analyzed period (from March 2003 to July 2008), it was verified the existence of cointegration between the two markets. Also it was observed that an increase of 1% in the gasoline price is responsible for the increase in 2.74% of the ethanol price. Although it was small the parameter of the correction mechanism in the obtained error, it points out that is possible to relate the behavior in the short and long term, in the analyzed series. Taking in consideration the obtained results, we arrived to the conclusion that the ethanol and gasoline markets are integrated in the long term, where variations in the gasoline price cause variations in the ethanol market.

Considerando as mudan?as do capitalismo, o texto estabelece como objeto de estudo as concep??es de Administra??o e Administrador, para o campo administrativo, na contemporaneidade. A tese ? suportada por uma pesquisa de campo cujo objetivo foi compreender criticamente as concep??es do campo administrativo sobre a Administra??o e o Administrador, em tempos de capitalismo flex?vel. Epistemologicamente, a pesquisa foi conduzida a partir da perspectiva cr?tica frankfurtiana, fundamentada em tr?s pares categ?ricos dial?ticos: (i) hist?ria versus naturaliza??o; (ii) pr?xis social versus sistema; e (iii) aliena??o versus emancipa??o; privilegiando o pensamento cr?tico vinculado ? primeira gera??o da Escola de Frankfurt. A literatura prevalente da ?rea de Administra??o foi revisada mediada pelas duas quest?es ontol?gicas que suportam a tese: O que ? Administra??o? e O que ? Administrador? para autores como Taylor, Fayol, Drucker, Ohno, Deming, Champy e Mintzberg. Metodologicamente, foi realizada uma pesquisa integralmente qualitativa, com uso de tr?s tipos de entrevistas: (i) entrevista narrativa com hist?ria de vida; (ii) entrevista com uso de elementos-est?mulo; e (iii) entrevista narrativa ficcional. Para compreens?o das narrativas, foi utilizada a t?cnica de an?lise hermen?utico-dial?tica. Os resultados indicam o predom?nio da concep??o pragm?tica-instrumental, no tocante ? Administra??o, pela qual ela continua a ser pensada e discursada como uma a??o tecnol?gica e teleol?gica, que utiliza saberes m?ltiplos e aprendizagens cambiantes como meios para alcance das finalidades do contexto organizacional mutante. Com rela??o ao Administrador, h? a emerg?ncia da concep??o est?tica para apresent?-lo, quando vinculado ?s organiza??es. Por esta concep??o, h? a migra??o do hist?rico estere?tipo do Administrador controlador e vigilante para a representa??o do Administrador como um profissional perform?tico. O segundo resultado, que se apresenta como o mais relevante em rela??o ao Administrador, ? o da fuga da profiss?o. A partir dos pares categ?ricos dial?ticos, esta tese prop?e algumas s?nteses provis?rias cr?ticas: (i) hist?ria-naturaliza??o: os sujeitos tomam como naturais a organiza??o empresarial e suas demandas, naturalizando as recentes mudan?as que, entre outras coisas, reduzem os postos gerenciais; (ii) pr?xis social-sistema: pela concep??o pragm?tica-instrumental, as experi?ncias dos Administradores s?o concebidas a partir do confinamento funcionalista em uma organiza??o-sistema; (iii) emancipa??o-aliena??o: tanto a forma naturalizada com que especificam as organiza??es e sua Administra??o quanto a pr?xis interrompida velada em uma experi?ncia reificada mostram-se como fen?menos intrinsecamente e subjetivamente alienantes e contraemancipat?rios. Por outro lado, atrav?s do movimento de fuga da profiss?o, os entrevistados parecem (re)significar o sil?ncio fundador da aliena??o associada ? condi??o de Administrador: a de pensar como capital, e n?o se pensar como trabalho. Finalmente, o texto prop?e que as possibilidades de emancipa??o deste profissional residem na tomada de consci?ncia de sua condi??o como integrante da classe trabalhadora, mesmo em tempos de riscos e incertezas. Assumindo-se como trabalhador, o Administrador poder? lutar pelo seu trabalho, repensando-o em novos termos, em que as dimens?es pragm?ticas-instrumentais que envolvem sua profiss?o possam ser dosadas e sempre mediadas por conte?dos substantivos e emancipat?rios
