Повний текст джерелаIn this thesis, we propose new strategies for energy conservation in wireless sensor networks, so that the operational time of these networks can be extended. The work can be divided into two main focus area, namely general wireless sensor networks, and healthcareoriented wearable sensor networks. In the first part of this thesis we provide a comprehensive survey of the existing energy-efficient mechanisms. Then, we propose two new solutions: the first one optimizes the displacement of a mobile base station as well as buffer usage and data routing at sensor nodes; the second one optimizes the deployment of wireless chargers in the network to satisfy the energy demand of the sensors. The second part of this thesis is dedicated to healthcare application where wearable sensors are used to remotely supervise a patient. We begin with a state-of-the-art of the energy-efficient techniques existing in the literature. We then introduce a new energy-efficient architecture that allows to optimize the lifetime of both the sensor and the base station. This is a context-aware solution that takes into consideration heterogeneous devices. Our results show that the lifetime of the sensor networks can be extended using the proposed strategies. All the results obtained are supported by numerical experiments and extensive simulations

Повний текст джерелаIn this paper it is described a method of creation of the shortest path algorithm for wireless sensor networks. Algorithm computes optimal shortest path and works on any wireless sensor networks topology. One of the limitations of wireless sensor nodes is their inherent limited energy resource. The limited available energy of sensor nodes is mainly problem making communication and computational processing. An energy efficient routing protocol can limit the number of nodes transmissions and the computational complexity of finding the shortest routing path. In the experimental part, the correct functionality of the algorithm is evaluated and the results are analized.

Повний текст джерелаNowadays technologies are being improved rapidly – extremely fast dedicated servers, high internet and network throughput, enables more and more applications to be moved to a virtual space, which is called ‘Cloud computing’. Cloud computing is responsible that all shared computer resources, like Software, Hardware and Network would be allocated for services in optimal way. This feature enables to appear new services, like media streaming, documents editing online etc. This kind of services are based on ‘Thin client’ architecture, which is especially important for mobile devices. Main feature of this architecture is that applications which require many computations, now can be executed in dedicated servers and results can be displayed in mobile device screen. Fact, that aplication is not executed in mobile device environment decreases probability that important information will be infected by viruses, worms etc. However, between many existing problems with mobile devices there are two major which should be stated in the first place: energy consumption and information security. The first issue is due to inadequate progress of computational resources and battery energy power (e.g., CPU speed, memory capacity is being increased several times within a few years, while battery power doubles only in a decade). The second issue is closely related with the first one. Today people want to work anywhere, so there is abillity that mobile devices including important information could... [to full text]

Повний текст джерелаNowadays major problem is energy consumtion in portable devices which has a battery. In this job we have evaluated energy consumption for Pocket PC. We wanted to see memory and processor influence in battery energy consumption. We have created a program which can do matrix multiplication and sparse matrix „storage by columns“ multiplication. During multiplication program takes battery information and saves it into the file. After that I have investigated the result and saw, that sparse matrix storage by columns multiplication is much more effectived than normal matrix multiplication. Sparce matrix storage by columns multiplication take less memory and more processor commands then normal matrix multiplication. We suggest to use sparse matrix storage by columns model instead simple model, because you can save much more operation time, battery resources and memory.

Повний текст джерелаThe environmental issues have during the last decenniums gained an increased role in both the political arena and in the market economy. The society is therefore more knowledgeable about the environment and our impact on it. Through this enlightened state, stakeholders tend to put pressure on the organizations of today. They, more or less willingly, incorporate this responsibility to be a part of their business. Entrepreneurs in the environmental area have seen this rising market as an opportunity to gain market shares and other positive outcomes. Organizations can, not only take a responsibility for the environment but, make a profit out of such a commitment. IT has become known as one of the contributors to facilitate the environmental impact, but much is left to be done, as IT equipment is one of the contributors to the damaging effects throughout its entire lifecycle. The study was conducted at Umeå Energi and was aiming towards an examination of their IT equipment and its environmental efficiency. Therefore, following questions were asked in this thesis: How environmental efficient is the IT equipment and the using of it in the organization today? What effects can different equipment and behavior lead to? Because of the opportunity to make the environmental work into a positive outcome another question where raised as well: Can the equipment and the using of it be environmental efficient and at the same time mean less expenditure? The study focused on the equipment in itself and the using of it. This was made through measuring of equipment and later on through a questionnaire survey. The results was then added together and analyzed in three different scenarios to illustrate the energy consumption of the equipment with the relation to the using of it. The result showed that both the equipment and the personnel working at Umeå Energi tended to be environmental inefficient. This led to establishing of proposals for changes and further work in this area.

Повний текст джерелаPurpose: Global greenhouse emissions are a major issue for both the country and the world. Therefore, one has to find alternatives and solutions to produce renewable energy. A vision for renewable energy is to produce property-related renewable energy. The aim of the study was to investigate renewable energy for self-production in new construction, taking into account the certification for Miljöbyggnad to contribute to a more positive development in environmental work. Method: The study is a qualitatively oriented research. To succeed in answering questions and attaining the objective of the study, data were gathered through semi-structured interviews and document analysis. The selection of respondents was based on the professional role of the chosen company. The documents that were analyzed were a checklist and an internal manual available in the cooperating company as well as documents from the Sweden Green Building Council that deals with Miljöbyggnad. Findings: The work on renewable energy is something that is prioritized despite the high one-time cost, as there is long-term profitability. Communication is therefore important during the design process, but there is a lack of factors in the finishing work. You do not necessarily need to install electricity production facilities in Miljöbyggnad as it is only part of the requirement for the Gold level. From a sustainability perspective, one should nevertheless install it in new production and supplement it with measuring instruments for the plants in order to follow up the result. Implications: The economic aspect has a major role in the design as it can prevent sustainability solutions. Therefore, financial support in energy issues is a good incentive for companies. Miljöbyggnad is then a good support in project planning for new production since a certification process is not always necessary. To develop the employee work structure, knowledge transfer should be given more priority. Limitations: The study is limited to Miljöbyggnad where only energy indicators have been studied. The case study is limited to apartment buildings to reduce the scope of the study. The results and recommendations presented are generally valid for those companies that have similar working methods and routines.

Повний текст джерелаApesar das recentes inovações tecnológicas, o setor dos transportes continua a exercer impactes significativos sobre a economia e o ambiente. Com efeito, o sucesso na redução das emissões neste setor tem sido inferior ao desejável. Isto deve-se a diferentes fatores como a dispersão urbana e a existência de diversos obstáculos à penetração no mercado de tecnologias mais limpas. Consequentemente, a estratégia “Europa 2020” evidencia a necessidade de melhorar a eficiência no uso das atuais infraestruturas rodoviárias. Neste contexto, surge como principal objetivo deste trabalho, a melhoria da compreensão de como uma escolha de rota adequada pode contribuir para a redução de emissões sob diferentes circunstâncias espaciais e temporais. Simultaneamente, pretende-se avaliar diferentes estratégias de gestão de tráfego, nomeadamente o seu potencial ao nível do desempenho e da eficiência energética e ambiental. A integração de métodos empíricos e analíticos para avaliação do impacto de diferentes estratégias de otimização de tráfego nas emissões de CO2 e de poluentes locais constitui uma das principais contribuições deste trabalho. Esta tese divide-se em duas componentes principais. A primeira, predominantemente empírica, baseou-se na utilização de veículos equipados com um dispositivo GPS data logger para recolha de dados de dinâmica de circulação necessários ao cálculo de emissões. Foram percorridos aproximadamente 13200 km em várias rotas com escalas e características distintas: área urbana (Aveiro), área metropolitana (Hampton Roads, VA) e um corredor interurbano (Porto-Aveiro). A segunda parte, predominantemente analítica, baseou-se na aplicação de uma plataforma integrada de simulação de tráfego e emissões. Com base nesta plataforma, foram desenvolvidas funções de desempenho associadas a vários segmentos das redes estudadas, que por sua vez foram aplicadas em modelos de alocação de tráfego. Os resultados de ambas as perspetivas demonstraram que o consumo de combustível e emissões podem ser significativamente minimizados através de escolhas apropriadas de rota e sistemas avançados de gestão de tráfego. Empiricamente demonstrou-se que a seleção de uma rota adequada pode contribuir para uma redução significativa de emissões. Foram identificadas reduções potenciais de emissões de CO2 até 25% e de poluentes locais até 60%. Através da aplicação de modelos de tráfego demonstrou-se que é possível reduzir significativamente os custos ambientais relacionados com o tráfego (até 30%), através da alteração da distribuição dos fluxos ao longo de um corredor com quatro rotas alternativas. Contudo, apesar dos resultados positivos relativamente ao potencial para a redução de emissões com base em seleções de rotas adequadas, foram identificadas algumas situações de compromisso e/ou condicionantes que devem ser consideradas em futuros sistemas de eco navegação. Entre essas condicionantes importa salientar que: i) a minimização de diferentes poluentes pode implicar diferentes estratégias de navegação, ii) a minimização da emissão de poluentes, frequentemente envolve a escolha de rotas urbanas (em áreas densamente povoadas), iii) para níveis mais elevados de penetração de dispositivos de eco-navegação, os impactos ambientais em todo o sistema podem ser maiores do que se os condutores fossem orientados por dispositivos tradicionais focados na minimização do tempo de viagem. Com este trabalho demonstrou-se que as estratégias de gestão de tráfego com o intuito da minimização das emissões de CO2 são compatíveis com a minimização do tempo de viagem. Por outro lado, a minimização de poluentes locais pode levar a um aumento considerável do tempo de viagem. No entanto, dada a tendência de redução nos fatores de emissão dos poluentes locais, é expectável que estes objetivos contraditórios tendam a ser minimizados a médio prazo. Afigura-se um elevado potencial de aplicação da metodologia desenvolvida, seja através da utilização de dispositivos móveis, sistemas de comunicação entre infraestruturas e veículos e outros sistemas avançados de gestão de tráfego.
Despite recent technological innovations, transportation sector is still producing significant impacts on the economy and environment. In fact, the success in reducing transportation emissions has been lower than desirable due to several factors such as the urban sprawl and several barriers to the market penetration of cleaner technologies. Therefore, the “Europe 2020” strategy has emphasised the relevance of improving the efficiency in the transportation networks through the better use of the existing infrastructures. In this context, the main objective of this thesis is increasing the understanding of how proper route choices can contribute to reduce emissions output over different spatial and temporal contexts. Simultaneously, it is intended to evaluate the potential of different traffic management strategies in terms of traffic performance and energy/environmental efficiency. The integration of empirical and analytical methods to assess the impact of different traffic optimization strategies on CO2 emissions and local pollutants constitutes one the main contributions of this work. This thesis has been divided in two main parts. The first is predominantly empirical, using field data as the main source of information. Using GPS equipped vehicles, empirical data for approximately 13200 km of road coverage have been collected to estimate energy and emissions impacts of route choice in three different scenarios: a medium-sized urban area (Aveiro), a metropolitan area (Hampton Roads, VA) and an intercity corridor (Oporto-suburban area). The second part, predominantly analytical, is essentially based on the output of traffic simulators and optimization models. The analytical component was based on the capability of microscopic traffic models to generate detailed emissions information and to generate link-based performance functions. Then, different traffic management strategies were tested to evaluate road networks in terms of traffic performance and emissions. Both outcomes of the empirical and analytical approaches have demonstrated that fuel use and emissions impacts can also be significantly reduced through appropriate route choices and advanced traffic management systems. The empirical assessment of route choice impacts has shown that both during off peak and peak periods, the selection of an appropriate route can lead to significant emissions reduction. Depending on the location, potential emissions savings of CO2 up to 25% and local pollutants up to 60% were found. The analytical approach has demonstrated that it is possible to significantly reduce system environmental costs (30%) by modifying traffic flow distribution along a corridor with 4 alternative routes. However, despite the positive results in terms of the potential for emissions reduction based on appropriate route choices, a number of important trade-offs that need to be considered in future implementations of eco-routing systems. Among these trade-offs it is worth noting that: i) different pollutants may lead to different ecorouting strategies, ii) the minimization of pollutants emissions often involves choosing urban routes (densely populated), iii) for higher penetration levels of eco-routing devices considering local pollutants, system environmental impacts can be higher than if drivers were guided under the traditional devices focused on travel time. With this research, it has been demonstrated that road traffic management strategies focused on minimizing CO2 emissions and fuel consumption can be compatible with the minimization of system travel time. On the other hand the minimization of local pollutants may lead to considerable increases in travel time. However, given the trend rate of reduction in the emissions factors of local pollutants, it is expected that such trade-offs would tend to be minimized in medium term. Thus, the developed methodology has great potential for further real life application, either through the use of nomadic devices, infrastructures to vehicle communication or different advanced traffic management systems.
