Purpose built teaching equipment for a laboratory based course in three phase machines and drives

The hazards associated with high voltage three phase inverters and the rotating shafts of large electrical machines have resulted in most of the engineering courses covering these topics to be predominantly theoretical. This paper describes a set of purpose built, low voltage and low cost teaching equipment which allows the "hands on" instruction of three phase inverters and rotating machines. By using low voltages, the student can experiment freely with the motors and inverter and can access all of the current and voltage waveforms, which until now could only be studied in text books or observed as part of laboratory demonstrations. Both the motor and the inverter designs are optimized for teaching purposes cost around $25 and can be made with minimal effort.

Three-phase machines and drives - equipment for a laboratory-based course

The hazards associated with high-voltage three-phase inverters and high-powered large electrical machines have resulted in most of the engineering courses covering three-phase machines and drives theoretically. This paper describes a set of purpose-built, low-voltage, and low-cost teaching equipment that allows the hands-on instruction of three-phase inverters and rotating machines. The motivation for moving towards a system running at low voltages is that the students can safely experiment freely with the motors and inverter. The students can also access all of the current and voltage waveforms, which until now could only be studied in textbooks or observed as part of laboratory demonstrations. Both the motor and the inverter designs are for teaching purposes and require minimal effort and cost

WREN: electronic management system for facilities management

This paper describes a case study of an electronic data management system developed in-house by the Facilities Management Directorate (FMD) of an educational institution in the UK. The FMD Maintenance and Business Services department is responsible for the maintenance of the built-estate owned by the university. The department needs to have a clear definition of the type of work undertaken and the administration that enables any maintenance work to be carried out. These include the management of resources, budget, cash flow and workflow of reactive, preventative and planned maintenance of the campus. In order to be more efficient in supporting the business process, the FMD had decided to move from a paper-based information system to an electronic system, WREN, to support the business process of the FMD. Some of the main advantages of WREN are that it is tailor-made to fit the purpose of the users; it is cost effective when it comes to modifications on the system; and the database can also be used as a knowledge management tool. There is a trade-off; as WREN is tailored to the specific requirements of the FMD, it may not be easy to implement within a different institution without extensive modifications. However, WREN is successful in not only allowing the FMD to carry out the tasks of maintaining and looking after the built-estate of the university, but also has achieved its aim to minimise costs and maximise efficiency.

Quantitative pulsed phase thermography applied to steel plates

Pulsed Phase Thermography (PPT) has been proven effective on depth retrieval of flat-bottomed holes in different materials such as plastics and aluminum. In PPT, amplitude and phase delay signatures are available following data acquisition (carried out in a similar way as in classical Pulsed Thermography), by applying a transformation algorithm such as the Fourier Transform (FT) on thermal profiles. The authors have recently presented an extended review on PPT theory, including a new inversion technique for depth retrieval by correlating the depth with the blind frequency fb (frequency at which a defect produce enough phase contrast to be detected). An automatic defect depth retrieval algorithm had also been proposed, evidencing PPT capabilities as a practical inversion technique. In addition, the use of normalized parameters to account for defect size variation as well as depth retrieval from complex shape composites (GFRP and CFRP) are currently under investigation. In this paper, steel plates containing flat-bottomed holes at different depths (from 1 to 4.5 mm) are tested by quantitative PPT. Least squares regression results show excellent agreement between depth and the inverse square root blind frequency, which can be used for depth inversion. Experimental results on steel plates with simulated corrosion are presented as well. It is worth noting that results are improved by performing PPT on reconstructed (synthetic) rather than on raw thermal data.

Nação, sociedade civil, estado e estado-nação: uma perspectiva histórica

Nação e sociedade civil são formas de sociedades politicamente organizadas, o estado, a instituição central, e o estado-nação a unidade político-territorial que se formaram a partir da Revolução Capitalista. Cada país de um estado-nação é constituído de uma nação ou uma sociedade civil, um estado e um território. Cada estado é a expressão de sua respectiva forma de sociedade politicamente organizada, mas a relação entre estado e sociedade é explicitamente dialética, uma vez que cada sociedade nacional cria seu estado para que este a regule. Considerando-se que essas definições são históricas, as formas de sociedade e, correspondentemente, as formas de estado se transformam de acordo com a história. Este trabalho apresenta de forma sumária estas formas históricas.

A qualidade do atendimento e os serviços prestados: um estudo sobre a relação de satisfação dos alunos do Curso de administração pública na Escola Superior de Ciências Sociais Unidade da Universidade do Estado do Amazonas - UEA

The theme of this dissertation is the quality in assistance and services rendered: a study on the satisfaction of the students from the Social Studies school. In a school, leader are supposed to always believe that the best form of attaining success derives from their performance in decentralizing activities, do away with barriers and help in the front line. This is the participative management. Students satisfaction is the goal. When the whole school community feels emotionally involved, success is assured, since all the educational segments are supposed to get together for achieving school success. When investment is made in the continued education of the school staff, such as the establishing a teaching of quality is sedimented. To have a school of quality in assistance and services rendered and, thereafter, to obtain favorable results, it is necessary for everyone to be aware of their roles, which is only possible through a cooperative effort on the part of the people forming the institution, with a commitment of the whole team: teaching, technical and administrative staff, as well as its external and internal clients, with values of excellence and relevance, which ought to be present in the whole of the educational effort. The four fundamental dimensions for a program of quality are: Planning to change; organizing to act; Acting to transform; Assessing to improve. In planning the institution establishes its objectives. In organizing it defines the structure for a more flexible action. In acting what has been established is implemented. In assessing it constantly improves the program of quality. To look for the students quality and satisfaction is the virtue of persistence is the doing right from the word go. To have a zeal and care in everything one does e for whom it is intended to, since to achieve the maximum in result with the least effort, reaching goal, objectives and finalities are everything the target population wishes.

O desafio de reconhecimento do sujeito cego em espaços públicos de representação

This work is funded based on the uneasiness with the concept of State as a public machine for development. Of State as a public machine to deliberate valid practices for valid methods and to limit valid subjects in valid spaces. In midst of this specific context, this work dedicates itself to investigate the following research problem: the mistaken recognition of the blind subject in public spaces of representation. For this reason, it was addressed the following question: how the blind subject is recognized in public spaces of representation? To answer the question, it was necessary to contextualize how the blind subject is being recognized in various public spaces of representation. In the international scope, the human rights debate held between the National States was analyzed (BRAND, 2005; KOERNER, 2002; UN, 2006). In the national arena, constitutional rights, federal laws, public policies and institutions representing the blind subject were examined (CABRAL, 2008; SARAVIA, 2006). Finally, in a local context, the fundaments of the concept of citizen for the subject recognition were investigated (AGAMBEN, 2002; RORTY, 1999, DELEUZE AND GUATTARI, 1996). The methodology included reports of national and international representatives in the Lusophone Countries Meeting for Dissemination and Implementation of the Convention on the Rights of Persons with Disabilities and, mainly, interviews with blind subjects. The data was processed by content analysis and was discussed based on the following categories: representation spaces; representation modes; representation amplitude; representation premises. The results show, regarding such spaces of representation, the growing importance of thinking the rights of persons with disabilities ¿ group in which belongs the blind subject ¿ as of the international and national scenario. However, the blind subjects announced alternative local spaces for representation: church, internet, radio, etc. Regarding the representation modes, the role of law and standards has been advocated specially in the human rights field. The importance of the cooperation between the States and the civil society to ensure, in practice, the rights achieved was also emphasized. But other forms of representation, directly linked to each interviewee¿ history, was important. Regarding the representation amplitude, there were arguments in defense of a conception of human dignity and freedom to all inhabitants of the globe. The lusophone event highlighted the concern of the cultural peculiarities of those involved in the meeting. The blind interviewees argued for citizenship as construction of instruments for freedom and autonomy, but recognized that this is not a clear desire between the blind people in general, and even less in society as a whole. With respect to the representation premises, the fundaments for the recognition of the blind subject were based on the primacy of reason at the expense of personal experimentation. Experimentation that serves as the foundation of a new form of recognition of the blind subject in public spaces of representation, one more interested in singularities, impenetrable by reason, unmovable to another, and which are irreducible to each subject. The final considerations suggest that if the State has a reason to be, this is not another than to offer instruments to manifest as many as the existential possibilities of the subject. This is the concept of State for development.

Solidariedade: uma possiblidade de integração no ensino básico e profissional das escolas técnicas do governo do estado do Rio de Janeiro

Esta pesquisa teve como objetivo identificar fatores críticos que possibilitarão implantação, com desenvolvimento coletivo individual, de uma Política Pública centrada na variável solidariedade, como meio de busca da integração para melhoria da Educação Básica Profissional do Sistema das Escolas Técnicas do Estado do Rio de Janeiro, sob responsabilidade da Fundação de Apoio Escola Técnica (FAETEC). pesquisa teve como referência de busca de dados informações, em sua maioria, de profissionais, alunos stakeholders alijados da participação concreta da atual Política Pública da FAETEC de suas respectivas unidades. Por isso Paulo Freire também serviu como referencial, principalmente no que diz em relação aos excluídos na página 19, do livro "Educação Mudança" quando escreve: "O verdadeiro compromisso solidariedade, não solidariedade com os que negam compromisso solidário, mas com aqueles que, na situação concreta, se encontram convertidos em coisas". Essas premissas fortaleceram escolha da pesquisa-ação como metodologia. Dos stakeholders citamos o Sindicato dos Técnicos Industriais do Estado do Rio de Janeiro (SINTEC-RJ). Associação de Pais Responsáveis de Alunos da Escola Técnica Estadual Adolpho Bloch (APRAETEAB) Conselho Regional de Engenharia Arquitetura (CREA-RJ) através de Técnicos que são Inspetores na atual gestão. Participaram também outras pessoas interessadas, cujas colaborações foram efetivas, todos se empenharam em colaborar para que, mesmo enfrentando dificuldades, pesquisa fosse suficiente mostrasse que estávamos fertilizando terreno propício implantação futura de uma nova Política Pública nessa Instituição, combatendo egoísmo, orgulho vaidade daqueles que, independentemente de ideologias já foram corroídos em seu caráter, mais, demonstram em seu corporativismo mal orientado, que egoísmo coletivo traz de malefícios, inclusive o de não conseguir ver possibilidade de um mundo melhor: uma outra globalização.

As percepções dos funcionários sobre as dimensões formais do Programa de controle de uma Instituição Bancária 2003

This work was developed in a financial institution, with the goal of identifying and analyzing the perception of the employees of the areas defined as the resource focus, according the formal dimension of the actual control program implemented in the institution, with the purpose of exploring the vulnerable points and the conflicting related to the increasing of performance of the employee¿s activities and new tools, concepts and news studies case. The work was conducted with the existing base of theories and concepts, following organizational controls, approachs like Elzioni¿s (1964), Amat¿s and Gomes¿s (2001) and Sturdy¿s, Knights¿s and Willmott¿s (1992). The research done was characterized as descriptive because it aims to describe the perceptions, expectations and the employee¿s profiles in the studied organization, such as field research, because it has the objective of promoting interviews and collecting the primary data and documental, because it will also be performed the analysis of the internal documents of the organization. The research also refers to a certain study case with a sectional cut and predominantly quantitative, but with support in quantitative technics for the initial tabulation of data that were analysed afterwords in interpretative form. The characteristics of the financial institution researched of the control program, has been formed predominantly of post-bureaucratic mechanisms focusing in results, in a hegemonic way expanded, of the utility type with strong alienatorian influences in the employees and with low incentive power, related to the increase of the employee¿s compromises. This way, the control program is noticed by the employees as a monitoring mechanism of actions and results, developed only to increase the institution profits, regardless of the impacts of the physical and emotional aspects and increasing, intuitively, the levels of internal dissatisfaction.

E-procurement associado a MRO: o caso Caixa Econômica Federal

A evolução da Tecnologia da Informação (TI) - mormente da Internet -, deslocando-se do meio acadêmico para a área de negócios, tem gerado discussões sobre seu impacto em modelos de negócios existentes. O Governo Brasileiro vem adequando a sua base legal, de forma a aproveitar os benefícios que esse novo ambiente de negócios pode trazer à estrutura pública. Este trabalho tem como principal objetivo identificar os benefícios alcançados pela Caixa Econômica Federal, no que se refere a melhorias na sua eficiência, ao implantar o seu site de compras MRO (Manutenção, Reparo e Operação). Através de metodologia de estudo de caso simples, busca-se analisar a importância estratégica da implantação do site de compras da Caixa Econômica Federal, investigando como as dimensões tecnológica, organizacional e cultural influenciaram a eficiência de seus processos produtivos. Embora os resultados obtidos sejam expressivos em relação ao tempo de recuperação do investimento, e promissores em relação ao potencial de reduzir custos administrativos da empresa, um fator considerado extremamente relevante é que o site tem grande potencial para agregar valor à performance financeira do banco. Neste contexto, a Caixa Econômica Federal deve aliar a oportunidade mercadológica gerada pela expertise desenvolvida, com a ociosidade que se cria com os ganhos de produtividade no processo, formando, assim, um produto com grande capacidade de geração de receita.

O Impacto da tecnologia da informação no ensino do curso de graduação em administração de empresas: estudo de caso do Centro Superior de Vila Velha

This study analyses the impact of Information Technology used in the undergraduate course of Business Administration at Centro Superior de Vila Velha. The Information Technology considered in the study is computer connected to the Internet, projectors, televisions and VCRs. To support the analysis, a survey was conducted in three different groups: directors (shareholders, principal, dean and chairperson), faculty and students. A questionnaire was developed for each group and validated through discussions and critical reviews by the academic committee for of this study. Items and questions were explicitly defined from the literature and based on expert opinion to provide respondents with a common understanding of the questions. The questionnaire used in the directors group focused mainly on motivation and on the investment planning for Information Technology in the institution. For the faculty and student groups, the questionnaire focused on the extent to what the group use of IT for classes and assignments, and to what extent the faculty understands the availability of IT to be used. The instrument was sent each person, for directors and faculty, and applied during class for students. The results show that although faculty and students perceive Information Technology are important for research and as a tool in the teaching and learning process, the available IT in the institution has been used under its capacity of utilization.

As percepções dos funcionários sobre as dimensões formais do programa de controle de uma instituição bancária um estudo de caso

Este trabalho foi desenvolvido em uma instituição financeira, com o objetivo de identificar e analisar a percepção dos funcionários das áreas definidas como foco da pesquisa, quanto às dimensões formais do atual programa de controle implementado na instituição, buscando explorar pontos vulneráveis e conflitantes ao aumento da performance das atividades dos funcionários e novas ferramentas, conceitos e frentes de estudos. O trabalho foi elaborado com base nas teorias e conceitos existentes quanto aos controles organizacionais, como as abordagens de Etzioni (1964), Amat e Gomes (2001) e Sturdy, Knights e Willmott (1992). A pesquisa realizada se caracteriza como descritiva, porque visa descrever as percepções, expectativas e os perfis dos funcionários da organização estudada. Os dados primários foram coletados por meio de entrevistas e os dados secundários através de documentos internos da organização. A pesquisa também se refere a um estudo de caso, com corte seccional e, predominantemente, qualitativo, mas com suporte em técnicas quantitativas para a tabulação inicial dos dados que posteriormente foram analisados de forma interpretativa. A conclusão do trabalho foi de que as características do programa de controle da instituição financeira pesquisada, é constituído, predominantemente, de mecanismos pós-burocrático, focado em resultados, de modo hegemônico expandido e do tipo utilitário, com fortes influências alienadoras nos funcionários e com baixo poder de incentivo, no tocante ao aumento do compromisso dos funcionários. Assim, o programa de controle é percebido pelos funcionários como um mecanismo de monitoramento de ações e resultados, desenvolvido apenas para aumentar os lucros da instituição, sem se preocupar com os impactos nos seus aspectos fisicos e emocionais e aumentando, intuitivamente, os níveis de insatisfação interno.

Uma comparação entre os custos atuais, custos por pacote e reembolso hospitalar para o procedimento de revascularização miocárdica

In Brazil, the supplemental healthcare system is going through a transition period from the traditional Fee-for-service reimbursement system to the Package reimbursement system, similar to the American model known as the Diagnoses Related Groups (DRG) system. Although the Package concept is nothing new to the hospital environment, it is still seldom used since this system calls for a level of control and analytical knowledge of hospital costs that are poorly developed in Brazilian institutions. This study focuses on determining how much the reimbursement for a Myocardial Revascularization Package actually covers of the current costs for patients submitted to this procedure. A prospective analysis method for determining the cost per patient has been developed and 13 patients were individually followed-up during all their hospitalization period. The expenses with intensive care unit and in-patient clinical care, as well as the type of admittance - whether elective or emergency - were determined for each patient. Additionally, all the resources and materials for the surgical procedure were included, comprising specialized personnel, surgical fees, procedures and tests, biomedical equipment, and all the materials and medication used during the hospital stay. Based on this data, the current total costs were calculated and compared to the reimbursement for the Package previously agreed upon by the institution and the healthcare carriers. The study found an average cost of BR$ 8,826 for a Myocardial Revascularization surgical procedure, while the respective reimbursement for the Package is of BR$ 7,476. Therefore, the reimbursement does not cover the current costs of the procedure.
