This thesis presents work that was done to improve the effectiveness of cleaning processes at an active pharmaceutical ingredient (API) manufacturing site that was in the phase of engineering trials and cleaning cycle development. Cleaning cycles executed on the site prior to the project were found to be inconsistent in cleaning the equipment to the desired specifications. Lack of repeatability of cleaning processes was hypothesized to be a resultant of inadequate process control and monitoring. Statistical Process Control (SPC) implemented using process automation was found to improve the success rate of cleaning processes significantly. SPC introduction required breaking down the cleaning operation into component steps, identifying critical process parameters (CPPs) and calculation of control limits using Shewhart Control Charts for these CPPs. Significant modifications were done to the automation controls for the recipe to ensure deviations from recipe are captured and appropriate actions are taken by the system or the operator to bring the process back in control. The success rate of cleaning processes improved from 38% to 72% post the implementation of Phase I of SPC with the newer non-conformances being associated to special external causes outside the control of the process. Real-time Multivariate Statistical Process Monitoring (RT-MSPM) was also introduced and piloted as a future opportunity for enhanced control and continuous quality improvement. Multivariate statistical process control eliminates the need to monitor multiple control charts (one for each variable) at the same time accounting for the correlations among process variables.

Full textThe high standard of competition in global market, the complexity of current manufacturing systems and the advances in Information Technology highlight the importance of the detailed production scheduling. Although classical approaches such as MRP perform this function quite well in different situations, these systems do not perform well in make-to-order (MTO) production systems. The finite capacity scheduling currently embedded within the software called APS (Advanced Planning & Scheduling) is a more interesting approach to achieve better performance in meeting due dates in production environments with complex routings and MTO strategy. Thus, the problem addressed in this study concerns the teaching of Production Planning and Control (PPC) models for intermittent production, with focus on the detailed production scheduling using MRP and APS approaches. In order to that, a teaching plan is proposed to present and differentiate these approaches. It includes the use of an educational case study named \"The Skateboard Factory\". In a playful but realistic way, the case presents, in its five stages, two hypothetical situations of use of scheduling systems. First, an MRP approach for planning in the skateboard factory, and second, one APS approach used by the truck supplier. The teaching plan was first applied to an undergraduate degree Production Engineering program. In this dissertation, a detailed description of the educational case study, along with the teaching plan, is provided. The results achieved in the case study and the students evaluation attest to the usefulness of the resources designed, and also that the strategies applied really improved the learning process. In this first application, it was also observed that high workload and the little weight in the final grade of the case study inhibit better results. In future applications, the case can be enhanced to include new stages on other important issues of the PPC discipline and the replacement of the software used.

A biometric system that employs one single biometric characteristic is constrained. This limitation can be reduced by fusing the information presented by multiple sources. A system that consolidates the evidence presented by multiple biometric sources is known as a multibiometric system. In such a context, this work proposes the security and persistence APIs of a multi-biometric architecture, which is capable of using one or more biometric modalities. In access control applications, a user might be forced to authenticate in order to give an unauthorized access to a criminal. As an alternative to this problem, the API uses a continuous authentication process, which verifies if the user identified at the start of the software application is still able to remain on the system, without human interferences or breaks in the process. Much of the literature on biometric system design has focused on system error rates and scaling equations. However, it is also important to have a solid foundation for future progress as the processes and systems architecture for the new biometric application are designed. Hence, the designed architecture made it possible to create a well-defined API for multibiometric systems, which may help developers to standardize, among other things, their data structure, in order to enable and facilitate templates fusion and interoperability. Therefore, the developed security and persistence APIs support a multi-biometric access control architecture. This architecture is extensible, that is, capable of easily comprising new biometric characteristics and processes, yet making it possible to use a template security mechanism. The APIs were designed and implemented. They were demonstrated by a prototype application, through which it was possible to conduct the test experiments.
Um sistema biométrico que empregue uma única peculiaridade ou traço característico é restrito. Esta limitação pode ser suavizada pela fusão dos dados apresentados por múltiplas fontes. Um sistema que consolida a evidência apresentada por múltiplas fontes biométricas é conhecido como um sistema multibiométrico. Nesse contexto, este trabalho propõe a interface de aplicação (API) de segurança e armazenamento de uma arquitetura multibiométrica, com habilidade de empregar uma ou mais modalidades biométricas. Em aplicações de controle de acesso, um usuário pode ser coagido a se autenticar para permitir um acesso indevido. Como alternativa para este problema, a API utiliza um processo de autenticação contínua, que verifica se o usuário que se identificou no início de uma aplicação de software ainda está apto a continuar no sistema, sem interferências humanas ou paralisações do processo. Grande parte da literatura sobre projeto de sistemas biométricos tem o foco nas taxas de erro do sistema e na simplificação de equações. No entanto, também é importante que se tenha uma base sólida para progressos futuros no momento em que os processos e a arquitetura da nova aplicação biométrica estiverem sendo projetados. Neste sentido, a arquitetura projetada permitiu a construção de uma API bem definida para sistemas multibiométricos, que deverá auxiliar os desenvolvedores a padronizar, entre outras coisas, sua estrutura de dados, de forma a possibilitar e facilitar a fusão de modelos biométricos e a interoperabilidade. Deste modo, a API de segurança e armazenamento desenvolvida suporta uma arquitetura multibiométrica de controle de acesso para autenticação contínua extensível, isto é, capaz de receber novas características e processos biométricos com facilidade, permitindo, ainda, o uso de um mecanismo de segurança de templates biométricos. A API foi projetada e implementada. Sua demonstração foi feita através de uma aplicação protótipo, por meio da qual foi possível realizar os testes.

Full textSwedish national grid (Svenska Kraftnät) is a state-owned public utility whose primary responsability is operation and maintenance of the Swedish power grid. Weed management is a part of the maintenance of the facilities of Svenska Kraftnät and today this is done with chemical pesticides. Svenska Kraftnät wishes to replace or reduce the use of chemical pesticides and the aim of this report was to investigate the possibility of doing that. One of the possible methods, NCC Spuma, was tested in one of the facilities of Svenska Kraftnät. The environmental impact of NCC Spuma was assessed in a Life Cycle Analysis (LCA). NCC Spuma is a thermal method for weed management offered by NCC Roads. The weed control is carried out with hot water and isolating foam. The weed is killed because of the exposure to hot water and the foam prolongs the time the hot water can damage the weed. The foam is formed when an extract, glucopon 225 DK, is added to the hot water.A field experiment was carried out to compare the effects of NCC Spuma and Roundup bio and also evaluate the practical use of NCC Spuma in the facility. The test showed that the use of NCC Spuma resulted in the greatest reduction in weed coverage. However, the standard deviations were very high for all of the results and in order to get a better comparison between the methods more tests are needed. The precipitation during the summer was very low which resulted in low weed growth. This in combination with big variation in weed coverage between the test squares from the start, contributed to the big standard deviation. In order to learn more about the emission of greenhouse gases from NCC Spuma an LCA was carried out. The result showed that the total emission of greenhouse gas for treatment of one square meter one time corresponded to 119,5 g CO2-equivalents. The biggest contribution was from the heating of water because of the use of biodiesel, the contribution was 85 g/m2. The second biggest contribution was from the production of the raw materials to the extract, 29 g/m2. The emissions due to transportation and production of the extract were considerably smaller. To reduce the use of chemical pesticides there are a number of actions Svenska Kraftnät can take. First of all they can make sure that the use of Round up bio is carried out properly according to the instructions, that the dose is adjusted to the weed and that it is only used on surfaces with weed. This since Roundup bio cannot be used to prevent the emergence of new weeds. NCC Spuma could be an alternative to Roundup bio but first the challenges in range due to poles and equipment in the facility should be solved. The time consumption can be a problem especially in the bigger facilities. Other methods that Svenska Kraftnät possibly could use are preventing actions like weed barriers or plants that cover the ground, acetic acid could also be an alternative. In the existing guidelines for the weed management it is said that the surface should kept free from weeds. This is rarely achieved and a target or a threshold value for tolerable amount weed would help the contractor to determine when weed control is necessary.

The present work had as objective to investigate the participation of the mechanisms adrenergics of the medial preoptic area (APM) in the salivary secretion induced for the peripheral colinergic stimulation (pilocarpine injection). Holtzman rats had been used (280-320 g). A part of the animals suffered electrolytic lesion in the APM through the ticket from electric chain (1mA x 3x10s), to serve as control, and another part of the animals was submitted to the same procedures of cerebral surgery, except that it was not displayed to the electric chain ticket (SHAM). Animals that suffered the surgery from implant of cannulas guides in the APM for the injection of adrenergics agonists and antagonists were also used. The saliva was collected using previously weighted and inserted balls of cotton in the mouth of the animal that was under anesthesia with quetamina (1mg/mL/kg). Salivation was induced for intraperitoneal injection (IP) of pilocarpine (1mg/mL/kg). The APM lesion in such a way reduced peripheral the pilocarpine-induced salivation group that suffered APM lesion 24 hours before the experiment (APM lesion 340,7 ± 41,1 mg/7min, versus SHAM 428,4 ± 31,6 mg/7min) as much as in the group that suffered APM lesion 5 days before the experiment (APM lesion 310,2 ± 35,4 mg/7min, versus SHAM 494,9 ± 35,5 mg/7min). Reduction in the peripheral pilocarpine-induced salivation was not verified in those animals that had suffered APM lesion 15 days before the experiment (APM lesion 461,6 ± 81,4 mg/7min, versus SHAM 575,7 ± 34,9 mg/7min). The injection of noradrenaline (80 nmol/0,5µL) in the APM did not reduce the peripheral pilocarpine-induced salivation (NOR + Pilo 356,0 ± 36,0 mg/7min versus Saline + Pilo 475,0 ± 73,0 mg/7min). This same drug in the dose of 160 nmol/0,5 µL reduced the peripheral pilocarpine-induced salivation (NOR + Pilo 251,0 ± 50,0 mg/7min versus Saline + Pilo 468,0 ± 59,0 mg/7min). The inhibitory effect of the injection in the APM of noradrenaline (160 nmol/0,5µL) in the peripheral pilocarpine-induced salivation was not reduced by the previous injection of the antagonist of adrenoceptors α2, RX-821002 in the dose of 80 nmol/0,5µL (RX + NOR + Pilo 244,1 ± 29,2 mg/7 min, versus Saline + NOR + Pilo 202,3 ± 34,8 mg/7 min). On the other hand, this same drug injected in the dose of 160 nmol/0,5µL, partially reverted the inhibitory effect of the injection in the APM of noradrenalina (160 nmol/0,5µL) in the peripheral pilocarpine-induced salivation (RX + NOR + Pilo 329,9 ± 77,8 mg/7min, versus Saline + NOR + Pilo 148,2 ± 30,3 mg/7min). The RX- 821002 injected in the APM in the dose of 320 nmol/0,5µL, failed in showing the reversion of the inhibitory effect of the injection in the APM of noradrenaline (160nmol/0,5µL) in the peripheral pilocarpine-induced salivation (RX + NOR + 261,3 ± 18,9 mg/7min, versus Saline + NOR + Pilo 320,4 ± 30,2 mg/7min). The antagonist of adrenergics receptors α1, Prazosin, did not reveal efficient, therefore the inhibitory effect of the injection in the APM of noradrenaline (160 nmol/0,5µL) in the peripheral pilocarpine-induced salivation was not reduced by the previous injection of the adrenergic antagonist α1, Prazosin, in the dose of 160 nmol/0,5µL (Prazosin + NOR + Pilo 223,6 ± 35,8 mg/7min, versus Saline + NOR + Pilo 256,0 ± 58,5 mg/7min). The results show that the noradrenaline injected in the APM reduces the peripheral pilocarpine-induced salivation and this effect is reduced by the previous blockade of the receiving adrenergics α2 of the same area, suggesting to the existence of an adrenergic α2 inhibitory mechanism of the salivation in the APM.
O objetivo deste trabalho foi investigar a participação dos mecanismos adrenérgicos da área preóptica medial (APM) na secreção salivar induzida pela estimulação colinérgica (injeção de pilocarpina) periférica. Foram utilizados Ratos Holtzman (280-320 g). Uma parte dos animais sofreu lesão na APM através da passagem de corrente elétrica (1mA x 3x10s), para servir de controle, uma outra parte dos animais foi submetida aos mesmos procedimentos de cirurgia cerebral, exceto que não foi exposta à passagem de corrente elétrica (lesão fictícia). Foram utilizados também animais que sofreram a cirurgia de implante de cânulas guia na APM para a injeção de agonistas e antagonistas adrenérgicos. A saliva foi coletada utilizando-se bolas de algodão previamente pesadas e inseridas na boca do animal que se encontrava sob anestesia por quetamina (1mg/mL/kg). A salivação foi induzida por injeção intraperitoneal (ip) de pilocarpina (1mg/mL/kg). A lesão da APM reduziu a salivação induzida por pilocarpina ip tanto no grupo que sofreu lesão da APM 24 horas antes do experimento (lesão APM 340,7 ± 41,1 mg/7min, vs. LF 428,4 ± 31,6 mg/7min) quanto no grupo que sofreu a lesão 5 dias antes do experimento (lesão APM 310,2 ± 35,4 mg/7min, vs. LF 494,9 ± 35,5 mg/7min). Não foi verificada redução na salivação induzida por pilocarpina ip nos animais que sofreram lesão 15 dias antes do experimento. (lesão APM 461,6 ± 81,4 mg/7min, vs. LF 575,7 ± 34,9 mg/7min). A injeção de noradrenalina (80 nmol/0,5µL) na APM não reduziu a salivação induzida por pilocarpina ip (NOR + Pilo 356,0 ± 36,0 mg/7min vs. Salina + Pilo 475,0 ± 73,0 mg/7min) Essa mesma droga na dose de 160 nmol/0,5µL reduziu a salivação induzida por pilocarpina ip (NOR + Pilo 251,0 ± 50,0 mg/7min vs. Salina + Pilo 468,0 ± 59,0 mg/7min). O efeito inibitório da injeção na APM de noradrenalina (160 nmol/0,5µL) na salivação induzida por pilocarpina ip não foi reduzido pela injeção prévia do antagonista de receptores adrenégicos α2, RX-821002 na dose de 80 nmol/0,5µL (RX + NOR + Pilo 244,1 ± 29,2 mg/7 min, vs. Salina + NOR + Pilo 202,3 ± 34,8 mg/7min). Já essa mesma droga injetada na dose de 160 nmol/0,5µL, reverteu parcialmente o efeito inibitório da injeção na APM de noradrenalina (160 nmol/0,5µL) na salivação induzida por pilocarpina ip (RX + NOR + Pilo 329,9 ± 77,8 mg/7 min, vs. Salina + NOR + Pilo 148,2 ± 30,3 mg/7min). O RX-821002 injetado na APM na dose de 320 nmol/0,5µL, falhou em mostrar a reversão do efeito inibitório da injeção também na APM de noradrenalina (160nmol/0,5µL) na salivação induzida por pilocarpina ip (RX + NOR + Pilo 261,3 ± 18,9 mg/7 min, vs. Salina + NOR + Pilo 320,4 ± 30,2 mg/7min). O antagonista de receptores adrenégicos α1, Prazosin, não se mostrou eficaz pois o efeito inibitório da injeção na APM de noradrenalina (160 nmol/0,5µL) na salivação induzida por pilocarpina ip não foi reduzido pela injeção prévia do antagonista adrenégico α1, Prazosin, na dose de 160 nmol/0,5µL (Prazosin + NOR + Pilo 223,6 ± 35,8 mg/7 min, vs. Salina + NOR + Pilo 256,0 ± 58,5 mg/7min). Os resultados mostram que a noradrenalina injetada na APM reduz a salivação induzida pela pilocarpina ip e que esse efeito é reduzido pelo bloqueio prévio dos receptores adrenérgicos α2 da mesma área, sugerindo a existência de um mecanismo adrenérgico α2 inibitório da salivação na APM.

Resumo: A formação de aglomerados empresariais é uma proposta tratada na literatura como amplamente viável às organizações que buscam a continuidade de suas operações em ambientes dinâmicos. Essa configuração promove o fortalecimento de economias regionais, a cooperação entre os membros e o compartilhamento de elementos em comum, como funcionários, fornecedores e financiadores. Como consequência da interação existente no meio, entende-se que os arranjos produtivos locais (APL) apresentam diversas condições que os caracterizam como uma instituição. Sob o respaldo da Nova Sociologia Institucional, concebe-se que em ambientes institucionalizados existem pressões que atuam sobre o comportamento dos elementos do grupo, conduzindo-os a ações parametrizadas ao contexto. Desse modo, o pressuposto inicial dessa pesquisa assume que as empresas localizadas nesse ambiente comportam-se sob processos de imitação de práticas. No entanto, a comum abordagem institucional, centrada em destacar as estruturas racionais que esculpem o comportamento organizacional, por vezes ignora que a criação e, sobretudo, o gerenciamento de empresas se faz por meio de pessoas. Isso posto, essa pesquisa definiu objeto de estudo o gestor-empreendedor do negócio, aquele indivíduo fundador que investe e toma decisões no ambiente empresarial. Acredita-se que empreendedores possuem um perfil individualizado dos demais, com qualidades particulares e capacidade independente para traçar e definir os mecanismos empregados para seu suporte decisorial. Além disso, a área comportamental defende que o ser humano é racionalmente capaz de compreender seu conhecimento e optar pela melhor alternativa para a resolução de problemas, vertente que sugere que empreendedores podem ser menos vulneráveis à influência do ambiente e mais auto direcionados às vontades próprias. Diante dessas condições, essa pesquisa questionou-se se duas características peculiares do empreendedor (a orientação empreendedora e a metacognição) seriam capazes de influenciar as práticas gerenciais utilizadas em seu empreendimento, mesmo sendo ele inserido em um mesmo ambiente institucional, que em tese, adotaria comportamentos modelados por reprodução de ações. Oportunamente utilizou-se da grande discussão sobre a complexidade de interpretação e desuso dos relatórios gerenciais para refletir sobre a existência de controles internos alternativos e simplificados com função similar aos preconizados teoricamente. Esses instrumentos foram denominados na presente pesquisa como proxies de controle gerencial e, operacionalmente, seriam práticas diárias empregadas no planejamento, execução e monitoramento das atividades empresariais que não são formalmente validadas pela teoria. Isso posto, a investigação realizou-se com o APL de confecção localizado no noroeste do Paraná (cidades de Cianorte e Maringá), por meio da aplicação in loco de um questionário com 121 gestores-empreendedores de indústrias do setor. A técnica aplicada na análise dos efeitos das variáveis relativas ao perfil do empreendedor sobre o uso de controles internos informais foi a modelagem de equações estruturais, sendo complementarmente apurada a capacidade de interação no distrito empresarial por meio da análise fatorial confirmatória (CFA). Os resultados da pesquisa permitem inferir que é possível que as características comportamentais do indivíduo influenciem nas práticas de gestão aplicadas no empreendimento, mesmo sendo ele inserido em um ambiente institucional. A orientação empreendedora foi capaz de predizer diretamente cerca de 38% do uso de controles gerenciais nos empreendimentos e 14% da performance empresarial. Esses achados ressaltam que, diferentemente do famoso tabu de que empreendedores são avessos ao emprego de instrumentos gerenciais e agem maiormente por intuição, existe uma significativa receptividade às práticas de controle gerencial. Entende-se que a utilidade desses artefatos seja uma condição implícita e colaborativa para o suporte decisorial no empreendimento, uma vez que o processo gerir um negócio para empreendedores pode envolver o equilíbrio entre a emoção do instinto empreendedor versus a razão manifestada nos relatórios de internos. Em adição, observou-se que as dimensões da orientação empreendedora do gestor exercem efeito no desempenho das atividades, porém em menor grau. Assume-se que elementos como autonomia, agressividade competitiva, propensão a assumir riscos, proatividade e inovação impulsionam o uso de estratégias eficazes na gestão, porém tornam-se menos eficazes para o desempenho organizacional se não são acompanhados do suporte oferecido pelos controles gerenciais. Face a essa condição entende-se que a possibilidade de projetar situações operacionais por meio desses artefatos podem ratificar o incipiente "feeling" do empresário. A metacognição, por sua vez, não suportou os efeitos empregados no modelo, porém acredita-se que algumas condições do ambiente do APL não levantadas na pesquisa influenciariam um comportamento parametrizado quanto a forma de guiar suas ações, como exemplo as condições de lucratividade do setor nessa região. Nesse sentido, a inserção de indivíduos no mesmo ambiente, guiados por um mesmo instinto, e sob as mesmas pressões situacionais poderiam estabilizar o conhecimento sobre as ações a serem adotadas. Por fim, um diagnóstico bastante interessante foi observado, embora a literatura pregue com frequência a caracterização do ambiente em estudo como uma instituição, os indicadores apurados não convergiram a mensuração de um coeficiente representativo na análise fatorial confirmatória. Acredita-se que possam existir outros aspectos que conduzem as empresas a organizarem-se nessa conjuntura territorial, como exemplo, benefícios econômicos.
Abstract: The formation of business clusters is a proposal treated in the literature as amply practicable to organizations seeking the continuity of its operations in dynamic environments. This configuration promotes the strengthening of regional economies, cooperation among the members and share common elements, such as employees, suppliers and financiers. As a result of interplay in the middle, it is understood that the local clusters (APL) present a number of conditions that characterize as an institution. Under the support of the New Institutional Sociology, it is conceived that in institutionalized environments there are pressures that act on the behavior of group members, leading them to parameterized actions to the context. Thus, the initial assumption of this research assumes that businesses located in this environment behave under realistic imitation processes. However, the common institutional approach focused on highlighting the rational structures that sculpt organizational behavior sometimes ignores the creation and, above all, the management companies is done through people. That said, this research object of study defined the manager-entrepreneur business, that founder individual who invests and takes decisions in the business environment. It is believed that entrepreneurs have an individualized profile of the others, with particular qualities and independent capacity to trace and define the mechanisms used for your decisorial support. Additionally, behavioral area argues that the human being is rationally able to understand their knowledge and choose the best alternative for solving problems, dimension suggesting that entrepreneurs may be less vulnerable to the influence of the environment and more self-directed to own wills. Faced with these conditions, this research questioned if two peculiar characteristics of the entrepreneur (entrepreneurial orientation and metacognition) would be able to influence the management practices used in their enterprise, even though he inserted in the same institutional environment, which in theory, would adopt behaviors modeled for reproduction actions. Opportunely was used the big discussion about the complexity of interpretation and disuse of management reports to reflect on the existence of alternative internal controls and simplified with a similar function to the recommended theoretically. These instruments were named in this research as a management control proxies and, operationally, would be daily practices used in the planning, execution and monitoring of business activities that are not formally validated by theory. Thus, the investigation was conducted with the confection APL located in the northwest of Paraná (cities of Cianorte and Maringá), through the attendance application of a questionnaire with 121 entrepreneurs-managers sector industries. The technique applied in the analysis of the effects of the variables on the entrepreneur's profile on the use of informal internal controls was the structural equation modeling, in addition being determined interaction capacity in the business district through confirmatory factor analysis (CFA). The research results allow us to infer that it is possible that the behavioral characteristics of the individual influence the management practices applied in the enterprise, even though it entered into an institutional environment. The entrepreneurial orientation was able to directly predict about 38% of the use of management controls in the enterprises and 14% of corporate performance. These findings point out that, unlike the famous conception that entrepreneurs are loathe to the use of management tools and act most keenly by intuition, there is a significant receptivity to management control practices. It is understood that the usefulness of these artifacts is an implicit and collaborative condition for decisorial support in the enterprise, since the process run a business for entrepreneurs can involve the balance between the entrepreneurial instincts emotions versus reason manifested in internal reports. In addition, it was observed that the dimensions of entrepreneurial orientation manager have an effect on the performance of activities, but to a lesser degree. It is assumed that elements such as autonomy, competitive aggressiveness, propensity to take risks, proactivity and innovation affect the use of effective strategies in management but become less effective for organizational performance if they are not accompanied by the support offered by the management controls. Given this condition is understood that the possibility of designing operational situations through these artifacts can ratify the incipient "feeling" of the entrepreneur. The metacognition, in turn, did not support the effects used in the model, but it is believed that some conditions APL environmental not in the survey influence a parameterized behavior in the order to guide their actions, for example the sector's profitability conditions in this region. In this sense, the inclusion of individuals in the same environment, guided by the same instinct, and under the same situational pressures could stabilize the knowledge of the actions taken. Finally, there was a very interesting diagnosis, although the literature describe the environment studied as an institution, not convergent measurement indicators representative of a coefficient in the confirmatory factor analysis calculated. It is believed that there may be other aspects that lead companies to organize this local context, for example, economic benefits.

Full textIn case of a fire at a construction site there is a risk of personal injury, property damage and stop in the building production that may be costly. There are shortcomings in the planning of fire safety at the construction site and at different construction methods. The planning of fire safety at construction sites are also in need of improvements according to how a construction site, and thus risks of fire, change during construction production. This by planning the fire safety along with the production of the building and that the fire safety is presented on workplace disposition plans. Fire protection design is mostly not included in the digital work method that Building Information Modeling (BIM) implies. The fact that the fire consultant is not involved with and works in BIM means that the benefits of collaboration between different disciplines cannot be utilized. The research on fire protection in BIM today focuses on the design of the completed building and how fire protection can be included in BIM. There is currently no research regarding both fire safety at the construction site and BIM modelling of the construction site. This leads to a gap between BIM as a working method at the construction site and the planning of fire safety. Because of mentioned problem areas, the study’s purpose was to investigate improvements for fire safety on construction sites. This by mapping out conditions and applicable areas where fire safety can be included in the planning of workplace disposition plans in time-dependent BIM models. The aim of the study was to provide a basis for future work methods in which fire safety, workplace disposition plans and BIM at construction sites are used together. To fulfill the purpose, a literature study and an interview study were conducted. The literature study was conducted to review published material regarding fire safety, construction site planning with workplace disposition plans, BIM at the construction site and BIM with fire safety design. Interviews were conducted to gain an insight into how people use fire safety documents, workplace disposition plans and BIM on construction sites (in practice). The information derived from theoretical knowledge and practical experience was analyzed to map the conditions and applicable areas where fire safety can be included in the planning of workplace disposition plans and time-dependent BIM models. This to bridge the gap between fire safety, workplace disposition plans and the use of BIM on construction sites. The identified areas that have been established are planning, communication and control and follow-up. To be able to work with fire safety and workplace disposition plans in time-dependent BIM model within the identified areas, there are some basic conditions that needs to be fulfilled. To be able to develop workplace disposition plans and make these time-dependent in the BIM model, education is needed to get the necessary knowledge and skills in both the design and production. There also needs to be an early collaboration between production and design to cover all areas of expertise needed in planning the production of a building with BIM. To be able to design workplace disposition plans in BIM, it is also a prerequisite that all disciplines work in the BIM model. If there is no information, such as information of the landscape, it is not possible to complete workplace disposition plans over the whole construction site in BIM. To develop time-dependent workplace disposition plans where fire safety are included in a BIM model, this study has proven to be beneficial in several areas. Planning the fire safety together with workplace disposition plans allows the fire protection at the construction site to be planned viregarding production and that the fire safety requirements can be implemented without the production being compromised. Time-dependent workplace disposition plans in a BIM model make it possible to visualize the changes at the construction site, thus predicting fire risks during different stages of the construction. Fire safety included in a BIM model can be a tool for improving communication at the construction site. This is because the information about the fire safety on construction sites inserted becomes more project-specific, which means that the information about the fire safety requirements can be easier to convey, clearer to follow and more understandable. With better information and increased knowledge about fire safety on construction sites, control and follow-up can be performed more effectively and therefore improving the fire safety by performing the controls with a higher quality. This gives the hope that fire protection during construction will be a major part of planning and designing the construction site and that this will lead to a safer construction site.

Full textAs empresas industriais enfrentam ambientes de produção cada vez mais difíceis e complexos. Fatores externos à empresa, como variações ao nível dos produtos e das quantidades solicitadas, bem como fatores internos, decorrentes de avarias, setups e tempos de processamento variáveis, entre outros, representam grandes desafios para o Controlo da Atividade de Produção (PAC – Production Activity Control). Lidar com estes aspetos de dinâmica e complexidade ao nível do PAC é crucial para a eficiência dos sistemas de produção. No entanto, os métodos correntemente utilizados baseados em abordagens centralizadas de planeamento nem sempre são adequados para lidar com ambientes de produção complexos e dinâmicos. O controlo autónomo da produção (APC - Autonomous Production Control) representa uma alternativa que visa melhorar o desempenho dos sistemas de produção pela reação rápida e flexível às mudanças ou alterações que possam ocorrer nos sistemas de produção. Para tal o APC transfere o poder de decisão para objetos logísticos (e.g., máquinas, transportadores, trabalho, etc.) “inteligentes” e distribuídos. No âmbito deste trabalho são estudados dois métodos para o controlo autónomo da produção, QLE (Queue Lenght Estimator) e PHE (Pheromones), em diferentes ambientes produtivos. É também proposta uma nova regra de despacho, baseada numa regra existente, para a sequenciação dos trabalhos em fila de espera das máquinas. Os métodos para o controlo autónomo da produção foram testados usando a simulação discreta, com vista a melhor perceber o seu comportamento, procurando encontrar formas de melhorar o seu desempenho. Os resultados obtidos mostram um desempenho superior do método QLE, nos diferentes ambientes produtivos considerados. Os resultados mostram ainda que é possível melhorar o desempenho deste método pela inclusão de informação relativa a avarias e a tempos restantes de processamento (no momento da decisão) no processo de tomada de decisão. Os resultados obtidos mostram ainda que a regra de despacho proposta tem um desempenho superior ao das restantes, com as quais foi comparada. O estudo realizado tem importantes implicações para a prática industrial e para a investigação nesta área.
Industrial companies face even more difficult and complex production environments. Factors external to the company, such as variations in the products and quantities requested, as well as internal factors, due to failures, setups and variable processing times, among others, represent major challenges for the Production Activity Control (PAC). To deal with these dynamic and complex aspects it is crucial the use of PAC to have a good efficiency in production systems. However, the methods currently used are based on centralized planning approaches and are not always adequate to deal with complex and dynamic production environments. Autonomous Production Control (APC) is an alternative that aims to improve the performance of production systems by rapid and flexible reaction to changes that may occur in production systems. To this end, the APC transfers the power of decision to logistic objects (e.g., machines, conveyors, orders, etc.) "intelligent" and distributed. In this work two methods for the independent control of production, QLE (Queue Lenght Estimator) and PHE (Pheromones), are studied in different productive environments. A new dispatch rule, based on an existing rule, is also proposed for the sequential queuing jobs of the machines. The methods for autonomous production control were tested using discrete simulation to better understand their behavior, looking for ways to improve their performance. The results show a superior performance of the QLE method, in the different productive environments considered. The results also show that it is possible to improve the performance of this method by including information regarding failures and remaining processing times (at the time of decision) in the decision-making process. The results also show that the proposed dispatch rule performs better than the others, with which it was compared. The study has important implications for industrial practice and for research in this area.

This thesis presents the development of a single-stage flyback switch-mode rectifier (SMR) and performs the comparative study of two current-mode control approaches. The general issues concerning power quality, survey of existing SMR circuits and current mode control methods are first explored. Then the analysis, design, implementation and control of a flyback SMR under discontinuous conduction mode (DCM) are made. For facilitating the circuit component design, the ratings of flyback SMR circuit components are derived in detail. As to the dynamic control studies, the average current control using switch current is first made. Then a varying-frequency charge-regulated approach is developed. Wherein the switch turn-on time is fixed and the off time instant is determined by the low-pass filtered switch current and the current command generated from the outer voltage loop. No dynamic current control and slope compensation are needed. The proposed control scheme possesses the advantages of having dispersedly distributed harmonic spectrum, robust current tracking control, ease of implementation using off-the-shelf integrated circuits, etc. In voltage control loop, the dynamic model is estimated. Then the quantitative feedback controller design is performed by the developed design procedure. Some simulated and experimental results are given to demonstrate the performance of the established SMRs and the effectiveness of the developed control methods.

The purpose of this research is to design an automatic irrigating system using a PC-based control algorithm. The environment parameters considered in this study involve: temperature, humidity, intensify of sunshine, and the characteristics of common plants. The irrigating system consists of three sub-systems: a control system, an irrigating device, and an operating interface. A user’s operating interface is installed in a personal computer which connects to a programmable logic controller. The irrigating system is designed to respond to any variation of environmental signals. As compared to simulated signals, real environmental signals result in a similar result using this control system. The ultimate good of this research, other then to propose a practical application of the automatic irrigating system, is to provide future researchers with a platform on the study of other PC-based control systems.
