Повний текст джерелаThe number of mobile devices (smartphone, tablet, laptop, etc.) and Internet users are continually increasing. Due to the accessibility provided by cloud computing, Internet and Internet of Things (IoT), users use more and more software applications which cause an increasing effect on gas emission. Thus, ICT (Information and Communication Technologies) is responsible of around 2% worldwide greenhouse gas emissions which is equivalent of that emitted by the airline industry. According to recent reports, the Intergovernmental Panel on Climate Change (IPCC), CO2 emissions due to ICT are increasing widely. Nevertheless, ICT, in allowing to solve complex problems in other sectors, can greatly and easily participate to reduce significant portion of the remaining 98% of global CO2 emissions. The use of software implies hardware operations which are physically responsible of energy consumption. Consequently, software is indirectly involved in the energy consumption. Thus, we need to reduce software energy consumption while maintaining the same functionalities for the software in order to build sustainable and green software. Firstly, in this thesis work, we define the terms sustainable and green in the area of software development. To build a software product, we need to follow a software engineering process. Hence, we define and describe sustainable and green criteria to be respected after each step of this process in order to establish a sustainable and green software engineering process. Then, we focus on the software energy consumption estimation. Many research works tried to propose various tools to estimate the energy consumption due to software in order to reduce carbon footprint. Unfortunately, these studies, in the majority of cases, consider only the CPU and neglects all others components. Existing power consumption methodologies need to be improved by taking into account more components susceptible to consume energy during runtime of an application. Writing sustainable, power efficient and green software necessitates to understand the power consumption behavior of a computer program. One of the benefits is the fact that developers, by improving their source code implementations, will optimize software power consumption. Moreover, there is a lack of analyzing tool to dynamically monitor source code energy consumption of several components. Thus, we propose GMTEEC (Generic Methodology of a Tool to Estimate Energy Consumption) which is composed of four layers assisting developers to build a tool estimating the software power consumption. Hence, in our work, respecting the layers of GMTEEC, we develop TEEC (Tool to Estimate Energy Consumption) which is based on mathematical formula established for each component (CPU, memory, hard disk, network) in order to estimate the total software energy consumption. Moreover, we add in TEEC the capacity to locate dynamically the hotpoints which are the parts of source code consuming the greater amount of energy in order to help and guide developers to optimize their source code and build efficient, sustainable and green software. We performed a variety of experiments to validate the accuracy and quality of the sustainable and green software engineering process and TEEC. The results demonstrate the possibility to save significant quantity of energy and time at limited costs with an important positive impact on environment

Повний текст джерелаThis work seeks to improve the energy efficiency of backbone networks by automatically managing the paths of network flows to reduce the over-provisioning. Compared to numerous works in this field, we stand out by focusing on low computational complexity and smooth deployment of the proposed solution in the context of Software Defined Networks (SDN). To ensure that we meet these requirements, we validate the proposed solutions on a network testbed built for this purpose. Moreover, we believe that it is indispensable for the research community in computer science to improve the reproducibility of experiments. Thus, one can reproduce most of the results presented in this thesis by following a couple of simple steps. In the first part of this thesis, we present a framework for putting links and line cards into sleep mode during off-peak periods and rapidly bringing them back on when more network capacity is needed. The solution, which we term ``SegmenT Routing based Energy Efficient Traffic Engineering'' (STREETE), was implemented using state-of-art dynamic graph algorithms. STREETE achieves execution times of tens of milliseconds on a 50-node network. The approach was also validated on a testbed using the ONOS SDN controller along with OpenFlow switches. We compared our algorithm against optimal solutions obtained via a Mixed Integer Linear Programming (MILP) model to demonstrate that it can effectively prevent network congestion, avoid turning-on unneeded links, and provide excellent energy-efficiency. The second part of this thesis studies solutions for maximizing the utilization of existing components to extend the STREETE framework to workloads that are not very well handled by its original form. This includes the high network loads that cannot be routed through the network without a fine-grained management of the flows. In this part, we diverge from the shortest path routing, which is traditionally used in computer networks, and perform a particular load balancing of the network flows. In the last part of this thesis, we combine STREETE with the proposed load balancing technique and evaluate the performance of this combination both regarding turned-off links and in its ability to keep the network out of congestion. After that, we use our network testbed to evaluate the impact of our solutions on the TCP flows and provide an intuition about the additional constraints that must be considered to avoid instabilities due to traffic oscillations between multiple paths

Повний текст джерелаSoftware sensors are a potent tool to improve biotechnological real time process monitoring and control. In the current project, algorithms for six partly novel, software sensors were established and tested in a microbial reactor system. Eight batch and two fed-batch runs were carried out with a recombinant Escherichia coli to investigate the suitability of the different software sensor models in diverse cultivation stages. Special respect was given to effects on the sensors after recombinant protein expression was initiated by addition of an inducer molecule. It was an objective to figure out influences of excessive recombinant protein expression on the software sensor signals.
Two of the developed algorithms calculated the biomass on-line and estimated furthermore, the specific growth rate by integration of the biomass changes with the time. The principle of the first was the application of a near infrared probe to obtain on-line readings of the optical density. The other algorithm was founded on the titration of ammonia as only available nitrogen source. The other two sensors analyzed for the specific consumption of glucose and the specific production of acetate and are predicted on an in-line HPLC system.
The results showed that all software sensors worked as expected and are rather powerful to estimate important state parameters in real time. In some stages, restrictions may occur due to different limitation affects in the models or the physiology of the culture. However, the results were very convincing and suggested the development of further and more advanced software sensor models in the future.

Повний текст джерелаInvestigations in many sectors of industry and research require the modelling of phenomena observed in the physics of continuous media. The partial differential equations describing these phenomena are solved using a wide range of numerical methods. The models used are increasingly sophisticated, from both a physical and numerical point of view. Software used to solve these problems must therefore be capable of evolving. This work is a continuation of research efforts devoted to the modelling of complex phenomena that began with the development of the Flux-Expert® program, based on the Finite Element Method. In order to extend the possibilities offered by this program, we decided to combine it with the Boundary Element Method. After reviewing the Boundary Element Method, we propose a general decomposition of the numerical solution of a problem using this method. We then describe the Green-Expert software developed on the basis of this analysis. The original aspect of the approach lies in the combination of a formulations generator and a general solver. This solver is capable of solving any problem described using a formulation coming from the Generator and a discrete geometry. The last part of this thesis is devoted to the validation phase. Examples of the combined use of the Boundary Elements and the Finite Element Methods are presented and examples of 2D and 3D resolution are used to validate the Green-Expert Solver and Generator

El deterioro en la calidad del aire es uno de los principales problemas ambientales que afectan a las ciudades alrededor del mundo, siendo la polución por material particulado 2,5 (MP2,5) la más peligrosa y mortal para el ser humano. Diversas también han sido las soluciones propuestas para ayudar a mitigar los efectos negativos de la contaminación atmosférica. De estas, una de las que ha tomado mayor fuerza durante el último tiempo corresponde a la utilización de los árboles urbanos para disminuir la contaminación al interior de las ciudades. Mediante el software I-Tree Eco, desarrollado por el Departamento de Agricultura de los Estados Unidos (USDA), se analizaron los efectos que posee el arbolado urbano sobre la interceptación y posterior absorción de MP2,5, al interior de la ciudad de Concepción, Región del Biobío, Chile. A partir de datos de calidad de aire, precipitación y la estructura de los árboles urbanos, el software permite estimar la cantidad de contaminación del aire removida durante un año por los árboles. Para lograr el propósito de la investigación, se utilizaron datos desde el Sistema de Información Nacional de Calidad del Aire (SINCA), mientras que el relleno de datos faltantes de esta base de datos, se realizó por medio del método de imputación de datos individual (SDEM Model). Por otra parte, la base de datos de precipitación se obtuvo desde la Red Agroclimática Nacional (AGROMET). Luego, mediante la fotointerpretación de imágenes satelitales a través de Google Earth, más las capas de levantamiento de espacios verdes, extraídas desde la red CEDEUS y el trabajo en terreno, se identificaron los elementos de la infraestructura verde de mayor relevancia, localizados al interior de la ciudad de Concepción. Junto con ello, se identificó al Parque Ecuador como uno de los espacios más importantes, debido a su tamaño y cercanía con el centro de la ciudad, asimismo, se realizó un inventario completo de los árboles urbanos presentes en su interior, identificando su estructura. Estos datos fueron procesados por el software, obteniendo la eliminación total de la contaminación por MP2,5, su capacidad de almacenamiento y secuestro de carbono, y la emisión total de compuestos orgánicos volátiles biogénicos (COVBs) que poseen los árboles urbanos del parque. Los resultados demuestran que el parque al año eliminó un total de 4,52 Kg de MP2,5, mientras que la tasa de eliminación fue de 0,13 gm-2 por cobertura arbórea; el almacenamiento de carbono fue de 350 toneladas de carbono y su secuestro bruto fue de 3,24 toneladas métricas por año, mientras que las especies del parque anualmente emiten un total de 50,48 Kg de COVBs.
Deterioration of air quality is one of the main environmental problems affecting cities around the world, with particulate matter pollution 2.5 (PM2.5) being the most dangerous and deadly for humans. The proposed solutions to help mitigate the negative effects of air pollution have been diverse; of these, one that has taken greater strength on recent times has been the use of urban trees to reduce pollution inside the cities. This way, through the software I-Tree Eco, developed by the U.S. Department of Agriculture (USDA), the effects of urban trees on the interception and subsequent absorption of PM2.5, inside of Concepción city, Biobío region, Chile were analyzed. Using data of air quality, precipitation and the structure of urban trees, the software allows to estimate the amount of air pollution removed by trees over a year. To achieve the objective of this research, data from the National Air Quality Information System (SINCA) was used, while the filling of missing data was done through the individual data imputation method (SDEM Model). Complete rainfall data was obtained from the National Agroclimatic Network (AGROMET). Then, through photointerpretation of satellite images from Google Earth, plus the layers of green space surveying, extracted from the CEDEUS network and workfield, the most relevant elements of the green infrastructure inside the city of Concepcion were identified. Ecuador Park was identified as one of the most relevant spaces on this city, and a complete inventory of the urban trees that are present inside of it was made, identifying its structure. The data was then processed by the software, obtaining the total elimination of the contamination by PM2.5, their storage capacity and carbon sequestration, and their emission of biogenic volatile organic compounds (BVOCs) that the urban trees of the park have. The results show that the park eliminated a total of 4.52 Kg of MP2.5 per year, while the elimination rate was 0.13 gm-2 for tree coverage; carbon storage was 350 tons of carbon and its gross sequestration was 3.24 metric tons per year, while the park species annually emit a total of 50.48 Kg of BVOCs.

Повний текст джерелаAs the digital communication systems evolve from GSM and now toward 5G, the supported standards are also growing. The desired communication equipments are required to support different standards in a single device at the same time. And more and more wireless Internet services have been being provided resulting in the explosive growth in data traffic, which increase the energy consumption of the communication devices thus leads to significant impact on global CO2 emission. More and more researches have focused on the energy efficiency of wireless communication. Cognitive Radio (CR) has been considered as an enabling technology for green radio communications due to its ability to adapt its behavior to the changing environment. In order to efficiently manage the sensing information and the reconfiguration of a cognitive equipment, it is essential, first of all, to gather the necessary metrics so as to provide enough information about the operating condition thus helping decision making. Then, on the basis of the metrics obtained, an optimal decision can be made and is followed by a reconfiguration action, whose aim is to minimize the power dissipation while not compromising on performance. Therefore, a management architecture is necessary to be added into the cognitive equipment acting as a glue to realize the CR capabilities. We introduce a management architecture, namely Hierarchical and Distributed Cognitive Radio Architecture Management (HDCRAM), which has been proposed for CR management by our team. This work focuses on the implementation of HDCRAM on heterogeneous platforms. One of the objectives is to improve the energy efficiency by the management of HDCRAM. And an example of a simplified OFDM system is used to explain how HDCRAM works to efficiently manage the system to adapt to the changing environment

In this study, life cycle analysis (LCA) of shea butter biodiesel from Well-to-Pump (WTP) is considered utilizing information gathered from Anuanom Industrial Bio Products Ltd. (AIBP) in Ghana, West Africa. The information presented in this report starts with shea plant cultivation, proceeds through harvesting of shea fruits, extraction of shea butter from shea kernels, and finishes with the production of shea butter biodiesel via homogenous acid–alkali transesterification reactions utilizing methanol. After researching the conversion of shea butter to biodiesel, the GREET software was explored as a tool to perform LCA. Shea butter is an excellent alternative feedstock to produce biodiesel on an industrial scale. Though research into shea plant cultivation and subsequent conversion into biodiesel in Ghana has not received formal attention, it has huge potential in the biodiesel industry. The tree originates in Africa and is tropical and drought-resistant. Although even some basic agronomic characteristics of shea butter are not yet fully understood, the plant enjoys a booming interest, which may hold the risk of unsustainable practice. The GREET software from the Argonne National laboratory of the US Department of Energy (DOE) was used in LCA. The software is a very useful tool specifically designed for LCA focused on energy and emissions of different production processes, including biodiesel production. This software is managed by DOE research laboratory and is made available for public use. The GREET software allow users perform many existing fuel production processes. To perform an LCA on shea butter biodiesel which is a new feedstock to the GREET software, some of the requisite information, and data input has to be sent to the Argonne National Laboratory personnel for input. For a new biodiesel feedstock such as shea butter which is not part of the GREET software database, it is important to work with the Argonne National laboratory to perform the LCA.

The increasing use of mobile devices, wireless networks and mobile applications highlights the importance of ensuring information security. This concern arises because of the risks involved in traffic sensitive information via wireless, since it does not limit the risk of attacks, as in conventional networks. Additionally, the trend in the use of sustainable practices advocated by the Green Computing imposes the need for designing flexible applications that seek to reduce consumption of resources such as energy. Thus, mechanisms for providing confidentiality of information passing over the wireless medium should consider the efficient allocation of computing resources. This is a key issue to be considered when designing secure mobile applications. Therefore, the protection mechanisms should balance the security level required in accordance with the consumption of resources allocated to provide it. The use of information that characterizes the current situation (context) can assist in this task. Thus, the use of appropriate protective security requirements of applications and combined with the context can identify situations where you need to raise or lower the security level in order to reduce the resource consumption of the device. This work proposes a Security Mechanism Dynamic Adaptation (MeSAD), focusing on confidentiality, able to adapt the level of security according to the context and reduce the resource consumption of mobile devices. The main objective is to find the balance point in the tradeoff between the level of security and resource consumption. In order to achieve this goal, this paper presents a tool to support the use of MeSAD during the development of mobile applications, and enable the assessments on the performance of cryptographic algorithms that are used in different devices.
A crescente utilização de dispositivos móveis, redes sem fio e aplicações móveis evidencia a importância da garantia de segurança da informação. Esta preocupação surge devido aos riscos envolvidos no tráfego de informações sensíveis por meio sem fio, uma vez que o meio não limita os riscos de ataques, tal como nas redes convencionais. Adicionalmente, a tendência no uso de práticas sustentáveis defendidas pela Computação Verde impõe a necessidade de concepção de aplicações flexíveis que busquem a redução do consumo de recursos, como o de energia. Assim, mecanismos para o provimento de confidencialidade de informações que trafegam por meio sem fio devem considerar a alocação eficiente de recursos computacionais. Esta é uma questão chave a ser considerada no momento da concepção de aplicações móveis seguras. Portanto, os mecanismos de proteção devem balancear o nível de segurança requerido de acordo com o consumo de recursos alocados para provê-lo. O emprego de informações que caracterizam a situação corrente (contexto) pode auxiliar nessa tarefa. Assim, a utilização de proteção adequada aos requisitos de segurança das aplicações e combinada com o contexto pode identificar situações nas quais será necessário aumentar ou diminuir o nível de segurança, de forma a diminuir o consumo de recursos do dispositivo. Esse trabalho propõe, portanto, um Mecanismo de Segurança com Adaptação Dinâmica (MeSAD), com foco na confidencialidade, capaz de adaptar o nível de segurança de acordo com o contexto e reduzir o consumo de recursos dos dispositivos móveis. O objetivo principal consiste em encontrar o ponto de equilíbrio no tradeoff entre nível de segurança e consumo de recursos. A fim de atingir este objetivo, este trabalho apresenta também uma ferramenta de suporte à utilização do MeSAD durante o desenvolvimento de aplicações móveis, além de possibilitar a realização de avaliações sobre o desempenho dos algoritmos criptográficos que são utilizados nos diferentes dispositivos.
Chevalier, Arthur. "Optimisation du placement des licences logicielles dans le Cloud pour un déploiement économique et efficient." Thesis, Lyon, 2020. http://www.theses.fr/2020LYSEN071.
Повний текст джерелаThis thesis takes place in the field of Software Asset Management, license management, use rights, and compliance with contractual rules. When talking about proprietary software, these rules are often misinterpreted or totally misunderstood. In exchange for the fact that we are free to license our use as we see fit, in compliance with the contract, the publishers have the right to make audits. They can check that the rules are being followed and, if they are not respected, they can impose penalties, often financial penalties. This can lead to disastrous situations such as the lawsuit between AbInBev and SAP, where the latter claimed a USD 600 million penalty. The emergence of the Cloud has greatly increased the problem because software usage rights were not originally intended for this type of architecture. After an academic and industrial history of Software Asset Management (SAM), from its roots to the most recent work on the Cloud and software identification, we look at the licensing methods of major publishers such as Oracle, IBM and SAP before introducing the various problems inherent in SAM. The lack of standardization in metrics, specific usage rights, and the difference in paradigm brought about by the Cloud and soon the virtualized network make the situation more complicated than it already was. Our research is oriented towards modeling these licenses and metrics in order to abstract from the legal and blurry side of contracts. This abstraction allows us to develop software placement algorithms that ensure that contractual rules are respected at all times. This licensing model also allows us to introduce a deployment heuristic that optimizes several criteria at the time of software placement such as performance, energy and cost of licenses. We then introduce the problems associated with deploying multiple software at the same time by optimizing these same criteria and prove the NP-completeness of the associated decision problem. In order to meet these criteria, we present a placement algorithm that approaches the optimal and uses the above heuristic. In parallel, we have developed a SAM tool that uses these researches to offer an automated and totally generic software management in a Cloud architecture. All this work has been conducted in collaboration with Orange and tested in different Proof-Of-Concept before being fully integrated into the SAM tool

Повний текст джерелаIn urban areas, competition between land development and ecological conservation is intense. To assist decision making, a better knowledge of those areas of interest is required. Regarding inadequacy data and methods needed for ecological network mapping in urban areas, the aim of our study is to develop a method for semi-automatic vegetation extraction with Very High Spatial Resolution Pleiades imagery (VHSR). Initially applied to training samples, the process is then be deployed to four French study areas (Toulouse, Muret, Pierrefite-Nestalas and Strasbourg). The reproducibility of this method over large urbanized areas is ensured by its simplicity and the results of a pixel-based classification (kappa coefficient higher than 85 %). This extraction workflow uses free or open-source software. This vegetation data is then used in order to model potential ecological connectivity in Toulouse’s urban and peri-urban areas. Impacts on biodiversity due to urban planning are assessed using graph theory. The “Boulevard Urbain Nord de Toulouse” project, a road infrastructure, is studied. Graph metrics have been calculated to assess the level of connectivity at habitat patches and landscape scales. We classified the importance of the patches which is cross-tabulated with planning documents (PLU, a local town planning) in order to locate conflict urban areas: between biodiversity preservation and urbanization. Depending on the issues set out by local actors and through the application filter, this thesis proposes a robust analytical tool and decision-making aid for landscape management and land planning

Повний текст джерелаBoth energy consumption analysis and energy-aware development have gained the attention of both developers and researchers over the past years. The interest is more notorious due to the proliferation of mobile devices, where energy is a key concern. There is a gap identified in terms of tools and information to detect and identify anomalous energy consumption in Android applications. A large part of the existing tools are based on external hardware (costly solutions in terms of setup-time), through predictive models (requiring previous hardware calibration) or static code analysis methods. We could not identify so far a tool capable of monitor all relevant system resources and components that an application uses and appoint its energy consumption, while being easily integrated with the application and/or with its development environment. Due to the lack of a tool capable of gathering all this information, a natural consequence is the lack of information about the energy consumption of applications and factors that can influence it. This dissertation aims to carry out a study on the energy consumption of applications and mobile devices in the Android platform, having developed in this scope the GreenSource infrastructure, a repository containing the source code, representative metadata and metrics relatively to a large number of applications (and respective execution in physical devices). In order to gather the results, an auxiliary tool has been developed to automatize the process of testing and collect the respective results for each one of the applications. This tool is a software-based solution, allowing to obtain results in terms of consumption through executions made directly on a physical device running the Android platform. The developed framework, the AnaDroid, has the capability to perform static and dynamic analysis of an application, being able to monitor power consumption and usage of resources for each application through tests execution. This is done following a whitebox testing approach, in order to test applications at source code level. It invokes calls to the TrepnLib library at strategic locations of the application code (through instrumentation techniques) to gain control over relevant portions of the source code, like methods and unit tests. In this way the programmer can have results about the use, state and consumption of resources such as energy, CPU, GPU, memory, sensor usage and complexity of developed test cases. The information gathered through the use of the AnaDroid over a large set of applications was stored in GreenSource backend. With the collected results, we expect to be able to characterize and classify applications, as well the tests developed for it. It is intended that this will be made publicly available and serve as a reference for future works and studies.
Quer a análise do consumo de energia, quer o desenvolvimento de aplicações com consciência neste sentido têm vindo a cativar a atenção de desenvolvedores e investigadores nos últimos anos. O interesse é mais notório devido à proliferação de dispositivos móveis, onde a energia é uma preocupação fundamental mas ainda pouco explorada. Como tal, existem lacunas identificadas em termos de ferramentas e informações para detectar e identificar o consumo anómalo de energia em aplicações Android. Grande parte das ferramentas existentes são baseadas em hardware externo (soluções dispendiosas em termos de tempo de setup), através de modelos preditivos (que exigem calibração prévia) ou métodos de análise estática de código. Não conseguimos identificar até ao momento uma ferramenta capaz de monitorizar de forma precisa todos os recursos e componentes relevantes do sistema usados por uma aplicação, bem como de determinar o seu consumo energético. Esta lacuna tem como consequência natural a falta de informação sobre o consumo de energia de aplicações e fatores que podem influenciá-lo. Esta dissertação tem como objetivo realizar um estudo sobre o consumo de energia na plataforma Android, tendo sido desenvolvido neste âmbito a infraestrutura GreenSource. Esta contém um repositório que engloba o código fonte, resultados e métricas relativas a um grande número de aplicações. A fim de obter resultados ilustrativos para um grande número de aplicações, foi desenvolvida uma ferramenta para automatizar o processo de teste e reunir os respectivos resultados. A ferramenta desenvolvida é baseada em software, permitindo obter resultados em termos de consumo através de execuções realizadas diretamente num dispositivo físico Android. Esta framework, denominada AnaDroid, possui a capacidade de analizar aplicações de forma estática e dinâmica, bem como de monitorizar o consumo e uso de recursos durante a sua execução. Para este efeito, são efetuadas invocações a uma biblioteca denominada TrepnLib, em locais estratégicos do código da aplicação para obter controlo sobre partes relevantes deste. Desta forma obtém-se resultados sobre o uso, estado e consumo de recursos, tais como consumo energético, CPU, GPU, memória, sensores. As informações reunidas através da execução do AnaDroid foram armazenadas na base de dados do GreenSource. Com todos os resultados coletados, pretende-se caracterizar e classificar energeticamente aplicações e testes desenvolvidos para estas. Pretende-se disponibilizar abertamente estes resultados, para que possam servir como referencia para futuros trabalhos, análises e estudos.

Повний текст джерелаEnergy consumption is nowadays one of the most important concerns worldwide. While hardware is generally seen as the main culprit for a computer’s energy usage, software too has a tremendous impact on the energy spent, as it can cancel the efficiency introduced by the hardware. Green Computing is not a newfield of study, but the focus has been, until recently, on hardware. While there has been advancements in Green Software techniques, there is still not enough support for software developers so they can make their code more energy-aware, with various studies arguing there is both a lack of knowledge and lack of tools for energy-aware development. This thesis intends to tackle these two problems and aims at further pushing forward research on Green Software. This software energy consumption issue is faced as a software engineering question. By using systematic, disciplined, and quantifiable approaches to the development, operation, and maintenance of software we defined several techniques, methodologies, and tools within this document. These focus on providing software developers more knowledge and tools to help with energy-aware software development, or Energyware Engineering. Insights are provided on the energy influence of several stages performed during a software’s development process. We look at the energy efficiency of various popular programming languages, understanding which are the most appropriate if a developer’s concern is energy consumption. A detailed study on the energy profiles of different Java data structures is also presented, alongwith a technique and tool, further providing more knowledge on what energy efficient alternatives a developer has to choose from. To help developers with the lack of tools, we defined and implemented a technique to detect energy inefficient fragments within the source code of a software system. This technique and tool has been shown to help developers improve the energy efficiency of their programs, and even outperforming a runtime profiler. Finally, answers are provided to common questions and misconceptions within this field of research, such as the relationship between time and energy, and howone can improve their software’s energy consumption. This thesis provides a great effort to help support both research and education on this topic, helps continue to grow green software out of its infancy, and contributes to solving the lack of knowledge and tools which exist for Energyware Engineering.
Hoje em dia o consumo energético é uma das maiores preocupações a nível global. Apesar do hardware ser, de umaforma geral, o principal culpado para o consumo de energia num computador, o software tem também um impacto significativo na energia consumida, pois pode anular, em parte, a eficiência introduzida pelo hardware. Embora Green Computing não seja uma área de investigação nova, o foco tem sido, até recentemente, na componente de hardware. Embora as técnicas de Green Software tenham vindo a evoluir, não há ainda suporte suficiente para que os programadores possam produzir código com consciencialização energética. De facto existemvários estudos que defendem que existe tanto uma falta de conhecimento como uma escassez de ferramentas para o desenvolvimento energeticamente consciente. Esta tese pretende abordar estes dois problemas e tem como foco promover avanços em green software. O tópico do consumo de energia é abordado duma perspectiva de engenharia de software. Através do uso de abordagens sistemáticas, disciplinadas e quantificáveis no processo de desenvolvimento, operação e manutencão de software, foi possível a definição de novas metodologias e ferramentas, apresentadas neste documento. Estas ferramentas e metodologias têm como foco dotar de conhecimento e ferramentas os programadores de software, de modo a suportar um desenvolvimento energeticamente consciente, ou Energyware Engineering. Deste trabalho resulta a compreensão sobre a influência energética a ser usada durante as diferentes fases do processo de desenvolvimento de software. Observamos as linguagens de programação mais populares sobre um ponto de vista de eficiência energética, percebendo quais as mais apropriadas caso o programador tenha uma preocupação com o consumo energético. Apresentamos também um estudo detalhado sobre perfis energéticos de diferentes estruturas de dados em Java, acompanhado por técnicas e ferramentas, fornecendo conhecimento relativo a quais as alternativas energeticamente eficientes que os programadores dispõem. Por forma a ajudar os programadores, definimos e implementamos uma técnica para detetar fragmentos energicamente ineficientes dentro do código fonte de um sistema de software. Esta técnica e ferramenta têm demonstrado ajudar programadores a melhorarem a eficiência energética dos seus programas e em algum casos superando um runtime profiler. Por fim, são dadas respostas a questões e conceções erradamente formuladas dentro desta área de investigação, tais como o relacionamento entre tempo e energia e como é possível melhorar o consumo de energia do software. Foi empregue nesta tese um esforço árduo de suporte tanto na investigação como na educação relativo a este tópico, ajudando à maturação e crescimento de green computing, contribuindo para a resolução da lacuna de conhecimento e ferramentas para suporte a Energyware Engineering.

EU-RoHS is important in influencing the world, and it is also a serious lash to Taiwan electrical and electronic manufacturing related industry. Hence, Taiwan electrical and electronic manufacturing related industry need to concern about EU-RoHS’s issue and do appropriate managing planning to keep ompetitive advantage in this time. Therefore, our research team has developed a Green Production Management System in hopes of helping Taiwan electrical and electronic manufacturing related industry control the quality of green products and assures the products could conform with EU-RoHS standard and avoid unnecessary penalties from occurring. To assure our Green Production Management System could reach the demands which we set up before and conform to user’s requests is the target in this research, we go through tests and verification to prove whether the system could achieve the target or not. In this research, integration testing and system testing are the main topics to discuss. Through our integration testing, we have assured that this system reaches the demands which we set up before. And through our system testing, we have also assured that this system reaches the demands of conforming to user’s requests. In the end of the research, we believe the system would get to the target we set up before and could almost reach user’s demand. In the future, we hope the system could be tested in the industry to be checked of its outcomes so that we could improve it and apply it widely.

In this thesis, we proposed an algorithm to divide rules to buckets. When a switch receives a packet, it needs to use flow table to decide how to process the packet. If we put flow table to TCAM, it will consume too much power, so we use our algorithm to divide rules. A switch will match index TCAM to decide to open which bucket, the buckets which are not opened can be closed to save power. There are counters in each rule in openflow standard, so we can know there is how many packets match each rule. We use the knowledge to calculate the probability of each rule matched and use it to design our algorithm. The object of our algorithm is to open entries in each search as less as possible. We will build a tree to represent rules and use dynamic programming algorithm to divide rules to buckets. Simulation result shows that our algorithm can reduce power consumed by TCAM very much.

The cloud-based teaching service system is a highly interactive one that combines and complements the Classroom of the Future. The present study adopted the quasi-experimental pretest posttest control group design and explored whether cloud-based teaching service system was useful to both the instructors who used the system and the students in terms of their natural science learning and learning attitude. Sixty-two eighth graders from two intact classes in New Taipei city participated in the study. One class was assigned as the experimental group while the other was the controlled group. The experimental group incorporated cloud-based teaching service system of science and technology to design natural science instruction. The controlled group was instructed with the traditional teaching method. Both groups were given a pretest and a posttest on natural science as well as a learning attitude questionnaire. The results showed that students in the experimental group performed significantly on the natural science posttest and exhibited more positive learning attitude than the controlled group students did. Students felt that with adopting cloud-based teaching service system, their class became livelier, more interactive, and safer. The instructors expressed concerns about the system’s stability; however, they were positive about the system and its’ use in natural science teaching.

Повний текст джерелаThe purpose of this postgraduate thesis is the analysis of Greek History on the Internet and the development of a complete web site which will focus on Greek History and more specifically on the history of the city of Nafpaktos. Nafpaktos is a city with a long and very interesting history, in which important events occurred (especially during the Ottoman period, with the legendary Naval Battle of Lepanto in 1571) which affected the history of the entire Greek nation. When the people of a country have awareness of their history, then they are also aware of their identity. History seals the specificity and the magnitude of the presence of the people of a country. Therefore, when a person does not know the history of his country, then he can not be considered a complete person. Nowadays, the Internet has significantly contributed to the promotion and learning of the history of each country. With the Internet, people from different countries and with different cultures and traditions can "visit" and learn about the country and its details that have made it famous around the world. Of course, Greece could never be absent from the Internet with its rich and long history. Greek History was and still is the main point of the study of many historians around the world. Indeed, for many people the ancient Greek civilization is perhaps considered the most significant civilization that has ever existed. There are surely many web sites which are refered to Greek History. In this thesis, it was made an attempt to be given a complete picture of the current situation. For this reason, they were reported some of the most remarkable web sites of Greek History on the Internet. Thus, this thesis can be a useful guide for all the users of the Internet who are interested in visiting web sites which will give them useful information about the history of Greece. Also, they were used new Internet “open source” technologies and more specifically the web development tool Joomla!, for the development of the web site which concentrates on the history of Nafpaktos. (It was also used XAMPP for the installation of Apache HTTP Server, MySQL, PHP and Perl). Joomla! is a free Content Management System (CMS). It is used for publishing content on the World Wide Web (WWW) and on intranets. The key feature of Joomla! is that it displays dynamic web pages, namely web pages which are created when required.
