Full textAbstract:
The input collected from warranty claims data links customer feedback with product quality. Results from warranty claim analysis can potentially improve product quality, customer relationships and positively affect business. However working on warranty claims data holds many challenges that requires a significant share of time devoted to data cleaning and data processing. The purpose of warranty claims analysis is to get the comprehensive overview of the reliability, costs and quality of household appliances produced by ASKO. While there are different ways to approach this problem, we will focus on non-parametric and semi-parametric methods, by using Kaplan-Meier estimators and Cox proportional hazard model respectively. These kinds of models are time dependent and therefore used for prediction of household appliance reliability. Even though non-parametric models are quite informative they cannot handle additional characteristics about observable product hence the semi-parametric Cox proportional hazard model was proposed. Apart from the reliability analysis, we will also predict warranty costs with probit model and observe inequality in household appliances part failures as a part of quality control analysis. Described methods were selected due to the fact that the warranty claims analysis will be practiced in future by ASKO’s quality department and therefore straight forward methods with very informative results are needed.

Full textAbstract:
This thesis presents a computer controlled system that partially automates the production
of upper-mouth orthodontic appliances. The machine performs the deposition and curing required to manufacture the acrylic portion of the appliance. Under this new process, the operator places the orthodontic wires and expansion screws on the surface of the dental cast, secures the cast onto the machine and describes the desired shape of the appliance through a graphical user interface. The machine then applies and cures the acrylic to form the finished appliance. Only minimal grinding and buffing is required.
The system consists of a robotic device that includes a two-axis platform for manipulating
dental casts; and a two-axis gantry for positioning an acrylic pump, ultraviolet lamp, laser and rotating mirror system, and a camera. The laser and camera are part of a range vision system for mapping the surface of the dental cast to obtain elevation and surface normal data. The pump and lamp are used to deposit and cure light activated liquid acrylic. The rotary table system provides orientation for the dental cast to permit surface mapping and acrylic deposition and curing. The table is able to orient the dental cast to avoid movement of the liquid acrylic on the surface of the cast before curing takes place. The machine software provides tool-workpiece collision avoidance, process planning, and machine function and motion control.
Several tests, including the complete production of orthodontic appliances, have been performed with the system. The average time for surface mapping of a dental cast is 11.5 minutes and the average time for acrylic deposition and curing is 54.3 minutes.<br>Applied Science, Faculty of<br>Mechanical Engineering, Department of<br>Graduate

Full textAbstract:
Environmental awareness and legislative pressures have made manufacturers responsible for the take-back and end-of-life treatment of their products. Therefore, manufacturers are struggling to find ways to recover maximum value from returned products. This goal can best be achieved by promoting multiple reuse programs as reuse is one of the most effective ways to enhance a sustainable engineering economy. Since the essential goal of the reuse strategy is to reuse parts, the reliability of used parts becomes a core issue. Research indicates that reuse is technologically feasible, associated with a significant manufacturing cost saving, and it does not compromise product quality. However, it is not easy to be applied in reality. There are several uncertainties associated with reuse, the most common is the uncertainty of the product???s quality after use. A widespread implementation of the reuse strategy could be triggered, subject to the availability of reliable methods to assess the useful remaining life of parts. The evolution of such a methodology would play a pivotal role in making decisions on the supply chain process and the recovery value of returned products. Reliability assessment by life cycle data analysis is the basis of this research. The proposed methodology addresses the problem of reliability assessment of used parts by considering two important aspects. It performs statistical as well as condition monitoring data analysis for decision-making on reuse. The analysis is carried out in two stages. Firstly, a wellknown reliability assessment procedure, the Weibull analysis, is applied to analyse time-tofailure data to assess the overall reuse potential of components. In the second stage, the used capacity (actual life) of components is determined by analysing their operating history (condition monitoring data). The linear and nonlinear regression analysis, Kriging procedures and artificial neural networks (ANN) are employed in this stage. Finally, the Weibull analysis and ANNs are integrated to estimate the remaining useful life of components/assemblies of a product at the end of its first life cycle. The model was validated by using life cycle data from consumer products.

Full textAbstract:
This thesis is dedicated to the study of load models and control of residential appliances. A load model base on computing an average dwelling augmented by a diversification process is introduced. This model is well-suited for studying the load group's natural and controlled dynamics. To validate this model, extensive simulations are employed. Two different strategies are proposed for the control of residential appliances: (1) aperiodic ON/OFF switching of the appliances; (2) continuous control of the thermostat temperature settings.<br>A mathematical framework based on Pulse Width Modulation theory is developed for the remote ON/OFF switching of residential appliances. Load Management System performs the switching actions on load groups in such a way that the resulting net demand of the appliances matches with a Load Reduction Target. The Load Reduction Target is obtained by modelling load groups as new generation resources into generation scheduling functions. The results of the proposed approach are compared with the results of the current practices and it is shown that the proposed scheme is an effective and flexible method that not only can realize the general form of Load Reduction Targets but also it is capable of error compensation, payback power regulation, switching schedules, incremental update and handling unequal peak powers of load groups.<br>For continuous control schemes, it is shown that during the control period, diversified states of the appliances do not change drastically and room temperatures within each load group are largely similar. Optimal control strategies are generated by employing Priority List, Linear Programming and Forward Dynamic Programming. The results show a close match between the Load Reduction Target and appliances' demand during control period.<br>Both methods are efficient and flexible. They allow incremental updating of schedules. Therefore, they are good candidates for use in real time operations.

Full textAbstract:
Many studies have conducted in the past that related to the domestic energy sector and households' appliances. These previous studies have explained the energy trends in the United Kingdom. In addition to this, the past studies have also provided wealth of information. However, all of these studies had some limitations. In addition, there were many gaps in the past studies regarding to the timing of usage the household's appliances and their daily contribution to the daily and peak demand. In this study, the researcher intended to overcome the limitations and gaps regarding the appliances time of use in the UK. In the present study, the data collected from Hillingdon Borough of London to ensure the study use the most reliable and valid data. Most importantly, suitable sampling and data collection technique applied in this study, which helped to obtain the appropriate data and outcome. All respondents were from the domestic sectors of the United Kingdom. Apart from this, to measure energy consumption in a more accurate manner, home appliances were categorised into several categories based on their functionality. Moreover, the household's appliances were categorised into time categories based on the time of use the appliances in order to determine the contribution of individual appliances at a certain time slot of the day to the total household consumption. Finally, the recommendations that have suggested in this study based on the current study as well as past studies. This means that the recommendations are a combination of all the major studies conducted. Additionally, based on the time a category of the household's appliances, a model was introduced that helped to determine how much of electrical appliances energy consuming in the UK households. Based on this model, the appliances consumption can managed and controlled. Thus, the model will help in mitigating the chances of the energy peak demand and will contribute towards energy and cost savings. Further, this study provides a valuable contribution to the field of smart homes as through the developed model, people can design a more efficient smart home. This specific method of determining energy demand has made the study more appropriate to forecast the 24h electricity demand and electricity price.

Wu, Jonas. "Scheduling Smart Home Appliances in the Stockholm Royal Seaport." Thesis, KTH, Reglerteknik, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-101437.
Full textAbstract:
This thesis investigates the optimal scheduling of smart home appliances with respect to economic benefits (electricity bill) and reducing environmental impacts (CO 2 emissions) for the Stockholm Royal Seaport project. The aim of this project is to develop a new urban district developing in the eastern Stockholm which will house 10,000 new apartments and 30,000 new office spaces where modern living is combined with environmental thinking to create sustainable living. In a previous work the scheduling objective was to minimize electricity bill, subject to various constraints such as sequential processing and consumer preferences. In this work the optimization framework will be extended to consider the trade-off between electricity bill and CO 2 emission minimization. This is a main concern in the Royal Seaport project. The study of this thesis shows that a well balanced result between minimizing the electricity cost and reducing the CO 2 emissions for an unusual cold day in Sweden (2010-01-05) with three typical home appliances showed that for formulation suggested in a previous work one could save up to 35.9% of electricity costs as well as reducing the CO 2 emissions with up to 16.5 %. This saving is with respect to the worst case scheduling for that specific day. The trade-off analysis is based on multi-objective Pareto frontier exploration, which requires solving multiple schedules instead of one as in the previous single objective case. In addition, for practical implementation the smart home control devices that will be used in the Stockholm Royal Sea project apartments will have a CPU and memory similar to those of a smart phone. Therefore there exists a need for faster implementation. The studies in this thesis indicate that the proposed simplified formulation can lead to a almost sixfold speed up in solve time, while providing schedules similar to those by the previous approach. The solve time of the proposed formulation decreases when the number of breakpoints in the piecewise linear objective decreases. A variant of the Ramer-Douglas-Peucker algorithm is applied to reduce the number of breakpoints while guaranteeing the objective function error is within a pre-specified bound. Finally, extensions of the current framework are discussed.

Full textAbstract:
Looking at the present demand for mobile services we can predict that there will be
an explosive growth in the usage of mobile appliances in the future. But these mobile
appliances suffer from significant problems related to storage restrictions and limited
computing resources. However, the increased demand for mobile services has resulted in
wide spread research to provide remote storage service for mobile appliance using iSCSI.
The iSCSI protocol enables the block level I/O and high-capacity storage service over
general IP networks. But iSCSI, in a client-server environment is very sensitive to latency
(delay time) and when applied to the mobile appliance results in a rapid performance
degradation when the mobile appliance (client) moves far away from the storage server. In
this research, authors describe a new availability remote storage system called an
intermediate storage server, which localizes the iSCSI target to the mobile appliance. Thus,
when the client moves far away from the primary storage server will automatically get
connected to the intermediate storage server rather than trying to establish connection with
the primary storage server. This reduces the latency or delay time involved in contacting and
accessing the resources from the storage server.<br>Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical and Computer Engineering

Driven by the advancement of smart electrical grid technologies, automated home energy management systems are being increasingly and extensively studied, developed, and widely accepted. A system like this is indispensable for and symbolic of a smart home. Mixed integer linear programming (MILP) together with dynamic electricity tariff and smart home appliances is a common way to developing energy management systems capable of automatically scheduling appliance operation and greatly saving monetary cost. This study transformed an existing plain MILP model to a goal programming model with priority to better address the conflict among each single appliance cost saving objective and user time preference objective. Constraints regarding the delays between pairs of closely related appliances are either extended or newly introduced. Numerical experiments on five appliances under different situations justify the validness of the proposed framework. Besides, the influences of key parameters on model performance are also investigated.

This Thesis discusses the Supply Chain Management topic, in particular the Supply Chain Planning (SCP) area is analyzed. It refers to evaluations concerning how best to plan the market demand and how to design and manage the company supply side in order to perceive the company financial and service level objectives. The analysis is entirely based on a case study: De’Longhi Appliances Srl, the Italian productive plant of De’Longhi Group, specialized in the production of coffee maker machines. It mainly analyzes the content of the Production & Material Planning office, where I did an internship period. It refers to the short term side of the supply chain planning, meaning the way Production & Material Planning personnel adjust the production program and plan the material procurement, so that to satisfy upper level market requests.
Moreover, it describes the De’Longhi Appliances supply relationship network and the way everyday information and data sharing are managed with suppliers.
This work is based on two key concepts: Flexibility and Collaboration. Flexibility refers to the ability of the company to properly answer to market requests through a flexible and dynamic configuration of internal operations. On the other side, collaboration refers to the relationship among offices and enterprises to improve the information sharing process, reduce the aggregate lead time, and properly answer to supply side criticalities. It refers to vertical collaboration when analyzing the relationship among internal offices and departments, while it deals with the concept of horizontal collaboration concerning the relationship among companies.
This Thesis is divided into three sections: 1_Content contextualization. It introduces the Supply Chain Management topic and the company object of the analysis, De’Longhi Group. Starting from a general overview, the business examined during the following sections is described; 2_Supply Chain Planning analysis. A description and an analysis of the current Supply Chain Planning process is provided, in order to explain how market demand comes into the factory and how it is translated into components production and purchasing orders; 3_Supply Chain Planning improvements. It introduces the Swim Lanes project that is dramatically changing the De’Longhi Appliances Supply Chain Planning process. After a brief introduction, the short-term side of this process s analyzed: Swim Lanes Operation. Possible medium-term evolutions are introduced in the last chapter.

On the other hand、the tremendous quantity of waste electric appliances caused a great deal of serious problems、especially pollution in environment. Since waste electric appliances still can be reused or recycled、and make value and benefits、many developed countries have emphasized the recovery process of waste electric appliances and legislated for managing the reverse logistics and regulating the producers』 responsibility. As for this issue in Taiwan、there is little attention and lake of complete regulations. Thus、this study focuses on investigating the process of reverse logistics in waste electric appliances. In this study、the data are collected to figure out the constitution of recycling system from experts and papers、and to make comparison of recycling systems between several developed countries. Furthermore、we refer to the results of analysis and consider the current situation in Taiwan、and try to design recycling system of waste electric appliances. The study concludes that the operation of close-looped systems is more efficiency because the government can control the process and quantity of recovery. We suggest that producers』 responsibility should be taken into account in the recycling system. The transportation must be assigned and monitored、and the control center must be built up to monitor operation of recycling system. Additionally、the mark tags have to be designed to tape every waste when collecting. Besides、secondhand sales should be involved in recycling system. The government should verify the quality of reused electric appliances to protect the right of consumers.

碩士<br>國立交通大學<br>應用藝術研究所<br>104<br>When talking about design, aside from the balance between functionality and aesthetics, it also needs to serve as a tool to trigger thinking. This study begins by reflecting consumerism, through literature survey and material exploration it finally focuses on the growing problem of e-waste. It attempts to change the relationship between human and appliance by emphasizing design and aesthetics, and introduce warmth and human nature into the cold-heart electronic products.
For the purpose of seeking the overlap regions between electrical equipment and crafts, I select two simple objects, lamp and loud-speaker, to create three items: “My Crystal Light”, “Loose Light”, and “Internal Sound”.
Cooperating with electronic professional during the developing process, I try to understand the mode of operation in the internal circuit and function of each electronic components form the designer’s point of view for its unique creation. The records with texts and images, not only offer the followers relevant material, they enable readers to have a broader understanding and imagination into the internal of electrical equipment.

Trabalho de Projeto de Mestrado, Informática, 2021, Universidade de Lisboa, Faculdade de Ciências<br>O consumo de energia tem vindo a crescer na União Europeia todos os anos, sendo de prever que, a curto prazo, se torne insustentável. No sentido de prevenir este cenário, a Comissão Europeia decidiu definir uma Estratégia Energética para a União Europeia, destacando dois objetivos: aumentar a eficiência energética e promover a descarbonização. Atualmente, cerca de 72% dos edifícios existentes na União Europeia não são energeticamente eficientes. Este problema motivou-nos à pesquisa e criação de soluções que permitam uma melhor avaliação do consumo energético por dispositivos elétricos em edifícios residenciais. Neste contexto, o trabalho desenvolvido nesta tese consiste no desenho de uma solução de monitorização remota que recolhe informações de consumo energético recorrendo a técnicas de intrusive load monitoring, onde cada dispositivo elétrico individual é continuamente monitorizado quanto ao seu consumo energético. Esta abordagem permite compreender o consumo de energia, em tempo real e no dia-a-dia. Este conhecimento oferece-nos a capacidade de avaliar as diferenças existentes entre as medições laboratoriais (abordagem utilizada no sistema de rotulagem de equipamentos elétricos de acordo com a sua eficiência energética) e os consumos domésticos estimados. Para tal, nesta tese exploram-se abordagens de machine learning que pretendem descrever padrões de consumo, bem como reconhecer marcas, modelos e que funções os dispositivos elétricos estarão a executar. O principal objetivo deste trabalho é desenhar e implementar um protótipo de uma solução de IoT flexível e de baixo custo para avaliar equipamentos elétricos. Será utilizado um conjunto de sensores que recolherá dados relacionados com o consumo de energia e os entrega à plataforma SATO para serem posteriormente processados. O sistema será usado para monitorar aparelhos comumente encontrados em residências. Além disso, o sistema terá a capacidade de monitorizar o consumo de água de aparelhos que necessitem de abastecimento de água, como máquinas de lavar e de lavar louça. Os dados recolhidos serão usados para classificação dos aparelhos e modos de operação dos mesmos, em tempo real, permitindo fornecer relatórios sobre o consumo energético e modo de uso dos aparelhos, com grande grau de detalhe. Os relatórios podem incluir o uso de energia por vários ciclos de operação. Por exemplo, um aparelho pode executar vários ciclos de operação, como uma máquina de lavar que consume diferentes quantidades de energia elétrica e água consoante o modo de operação escolhido pelo utilizador. Toda a informação recolhida pode ser posteriormente utilizada em novos serviços de recomendação que ajudaram os utilizadores a definir melhor as configurações adequadas a um determinado dispositivo, minimizando o consumo energético e melhorando a sua eficiência. Adicionalmente toda esta informação pode ser utilizada para o diagnóstico de avarias e/ou manutenção preventiva. Em termos de proposta, o trabalho desenvolvido nesta tese tem as seguintes contribuições:
Sistema de monitorização remota: o sistema de monitorização desenhado e implementado nesta tese avança o estado da arte dos sistemas de monitorização propostos pela literatura devido ao facto de incluir uma lista aprimorada de sensores que podem fornecer mais informações sobre os aparelhos, como o consumo de água da máquina de lavar. Além disso, é altamente flexível e pode ser implementado sem esforço em dispositivos novos ou antigos para monitorização de consumo de recursos.
Conjunto de dados de consumo de energia de eletrodomésticos: Os dados recolhidos podem ser usados para futura investigação científica sobre o consumo de consumo de energia, padrões de uso de energia pelos eletrodomésticos e classificação dos mesmos.
Abordagem de computação na borda (Edge Computing): O sistema de monitorização proposto explora o paradigma de computação na borda, onde parte da computação de preparação de dados é executada na borda, libertando recursos da nuvem para cálculos essenciais e que necessitem de mais poder computacional.
Classificação precisa de dispositivos em tempo real: Coma proposta desenhada nesta tese, podemos classificar os dispositivos com alta precisão, usando os dados recolhidos pelo sistema de monitorização desenvolvido na tese. A abordagem proposta consegue classificar os dispositivos, que são monitorizados, com baixas taxas de falsos positivos.
Para fácil compreensão do trabalho desenvolvido nesta tese, de seguida descreve-se a organização do documento. O Capítulo 1 apresenta o problema do consumo de energia na União Europeia e discute o aumento do consumo da mesma. O capítulo apresenta também os principais objetivos e contribuições do trabalho. No Capítulo 2 revê-se o trabalho relacionado em termos de sistema de monitorização remota, que inclui sensores, microcontroladores, processamento e filtragem de sinal. Por fim, este capítulo revê os trabalhos existentes na literatura relacionados com o problema de classificação de dispositivos usando abordagens de machine learning. No Capítulo 3 discutem-se os requisitos do sistema e o projeto de arquitetura conceitual do sistema. Neste capítulo é proposta uma solução de hardware, bem como, o software e firmware necessários à sua operação. Os algoritmos de machine learning necessários à classificação são também discutidos, em termos de configurações necessárias e adequadas ao problema que queremos resolver nesta tese. O Capítulo 4 representa a implementação de um protótipo que servirá de prova de conceito dos mecanismos discutidos no Capítulo 3. Neste capítulo discute-se também a forma de integração do protótipo na plataforma SATO. Com base na implementação feita, no Capítulo 5 especificam-se um conjunto de testes funcionais que permitem avaliar o desempenho da solução proposta e discutem-se os resultados obtidos a partir desses testes. Por fim, o Capítulo 6 apresenta as conclusões e o trabalho futuro que poderá ser desenvolvido partindo da solução atual.<br>Energy consumption is daily growing in European Union (EU). One day it will become hardly sustainable. For this not to happen European Commission decided to implement a European Union Strategy, emphasizing two objectives: increasing energy efficiency and decarbonization. About 72% of all buildings in the EU are not adapted to be energy efficient. This problem encourages us to create solutions that would help assess the energy consumption of appliances at residential houses. In this thesis, we proposed a system that collects data using an intrusive load monitoring approach, where each appliance will have a dedicated monitoring rig to collect the energy consumption data. The proposed solution will help us understand the real-life consumption of each device being monitored and compare the laboratory measurements observed versus domestic consumption estimated by the energy consumption based on the EU energy efficiency labelling system. The system proposed detects device consumption patterns and recognize its brand, model and what actions that appliance is executing, e.g., program of washing in a washing machine. To achieve our goal, we designed a hardware solution capable
of collecting sensor data, filtering and send it to a cloud platform (the SATO platform). Additionally, in the cloud, we have a Machine Learning solution that deals with the data and recognizes the appliance and its operation modes. This recognition allows drawing a device/settings profile, which can detect faults and create a recommendation service that helps users define the better settings for a specific appliance, minimizing energy consumption and improving efficiency. Finally, we examine our prototype approach of the system implemented for targeted objectives in this project report. The document describes the experiments that we did and the final results. Our results show that we can identify the appliance and some of its operation modes. The proposed approach must be improved to make the identification of all operation modes. However, the current version of the system shows exciting results. It can be used to support the design of a new labelling system where daily operation measures can be used to support the new classification system. This way, we have an approach that allows improving the energy consumption, making builds more efficient.

Trabalho de Projeto do Mestrado Integrado em Engenharia Física apresentado à Faculdade de Ciências e Tecnologia<br>Os eletrodomésticos ajudam-nos diariamente com as tarefas domésticas. Com o uso estes começam a desenvolver anomalias que se traduzem em consumos de energia mais elevados e, muita das vezes, em avarias que obrigam a reparações que representam um incómodo e um custo inesperados. Neste projeto iniciou-se o desenvolvimento de um sistema de monitorização avançada para eletrodomésticos que permite detetar falhas antecipadamente através da análise detalhada de parâmetros operacionais. Possibilitando assim um maior controlo dos gastos energéticos e das reparações do eletrodoméstico.O sistema reutiliza uma tomada desenvolvida na VPS, a idPlug, que possibilita a medição de parâmetros elétricos (corrente, tensão, potência) e análise do sinal de corrente usando técnicas no domínio da frequência. A deteção de falhas baseia-se num método que compara a evolução dos máximos da transformada de Fourier da corrente. Para simplificar a operação do sistema foi desenvolvido interface web local que permite visualizar os dados e parametrizar o dispositivo.Os requisitos especificados foram verificados através de um conjunto de testes utilizando inicialmente um motor sem carga. Posteriormente, o sistema foi testado usando um mini-frigorífico, tendo o dispositivo detetado corretamente todos os arranques do motor. Em seguida, realizaram-se testes com uma máquina de lavar onde se verificaram falhas no algoritmo implementado devido ao facto deste eletrodoméstico possuir vários elementos de carga (motores e resistência de aquecimento) e diferentes ciclos de lavagem. Assim, a evolução futura do algoritmo deverá permitir a identificação de diferentes ciclos de operação. De igual forma, a deteção de falhas poderá incluir a análise de longo termo dos dados recolhidos usando técnicas de reconhecimento de padrões e agregação.<br>Home appliances help us with domestic tasks every day. With usage, they start to develop small anomalies which translate into higher energy consumptions and, most of the times, faults that require repairs that represents an unwanted extra cost. This project started the development of an advanced monitoring system for home appliances, which allows detecting anomalies through a detailed analysis of operational parameters. So, this system allows for better control of energy and appliance repair costs.The system reuses a device developed in VPS, the idPlug. This device measures electrical parameters (current, voltage, power) and analyses the current signal using techniques in the frequency domain. The fault detection is based on a method that compared the maximums of the current Fourier transform. To simplify the system operation a local web interface was developed which allows data visualization and device parameterization.The specified requirements were checked by a set of tests using a motor with no load. Afterwards, the system was tested using a mini-refrigerator where the number of motor starts correctly identified. Then, the system was tested using a washing machine that revealed some shortcomings in the implemented algorithm due to the existence of several load elements (motors and heating elements) and different washing cycles. So, a future algorithm evolution should allow the washing cycle identification. Likewise, fault detection may include a long-term analysis of the collected data using pattern recognition and aggregation techniques.

Home appliances were, until not very recently, isolated devices uncapable of communicate with others. With the recent technological advances is it possible nowadays to connect all these devices to the internet enabling them with the capacity to communicate between them and also the possibility to store and analyse the data generated making them more efficient.
Due to these advancements, terms like Internet of Things and Cloud Computing surfaced. These terms represent architectures that allow communications and interactions between devices. The potential of these technologies is substantial for the improvement of productivity and eco-nomic impact.
These advancements allowed home appliances to generate an enormous amount of data, and as repercussion, the need for structures able to receive, storage and process the data emerged.
The present document contains a proposition of an architecture that allows to collect and send home appliances’ data to the Cloud, a way to store and make them available to other applications and a platform that allows the data’s visualisation and analysis. The proposed architecture was tested with a refrigerator offered by Electrolux inserted in the ProSEcO project.

<div>With the United States being the world’s second largest consumer of primary energy, research into areas of significant consumption can provide large impacts in terms of the global energy consumption. Buildings account for 41% of U.S. total energy consumption with the residential sector making up a majority. Household appliances account for the second largest site energy consumption at 27%, after the HVAC system for the U.S. residential sector. Federal appliance standards have been instrumental in improving efficiencies but have been increasing aggressively to where it is unknown what suitable technologies can support this rate of increase. Thermally integrating residential appliances by leveraging waste heat recovery goes outside standards and has not been adequately explored by connecting all residential appliances. Limited studies exist focused only on single appliances connected to waste heat recovery or being thermally integrated. Preliminary modeling on waste heat availability from five major appliances, namely refrigerator-freezer, clothes dryer, clothes washer, dishwasher, and cooking oven was conducted. Conservative estimates predict the total amount of heat recovery to be around 2,000 kWh/year; clothes dryer - 137 kWh/year, clothes washer - 60 kWh/year, 1,500 kWh/year- refrigerator-freezer, 27 kWh/year – dishwasher, and 178 kWh/year – cooking oven. The cooking oven presents technical challenges coupled with safety concerns. The clothes dryer and refrigerator-freezer can deliver useful water temperatures and reduce compressor power consumption, up to 20%. The dishwasher has better opportunity as a heat sink to offset the internal heater, 0.17 kWh of electricity/cycle for heating wash water. The clothes washer drains large volumes of water available for heat recovery and can offset the impact of using high temperature washes with improved wash performance. </div><div>Modelica appliance models have been developed for four of these five appliances. The Modelica models capture individual use and the predictions of the RF and DW were compared against available experimental data. The individual models have been connected to a simple storage tank model to simulate the integrated appliance system. An integrated appliance prototype was designed and fabricated for the collection of experimental data. Comparisons made between the experimental data and the integrated appliance simulation results adjusted the modeling approach and improved agreement with collected data. After tuning, ideal modifications to each appliance are made and reflected in a new integrated model. A parametric study is conducted on ideal improved, thermally capable appliances under a 1-week schedule for two different tank sizes. For 300L and 150 L tank sizes, the appliance total energy for the week is roughly 30.5 kWh compared to a baseline appliance system with no thermal resource sharing at 33.8 kWh. At an electricity cost of $0.15/kWh, the cost savings for the integrated system is a little over $0.40/week. Furthermore, the savings is completely diminished when considering the required auxiliary power to support the exchange of heat between each appliance and storage tank. The impact of tank size should be explored further to identify a critical tank size where the system savings is no longer available. Accounting for all the domestic hot water needs of the home would generate an improved picture where integrated appliances have technical feasibility. </div><div><br></div>

碩士<br>銘傳大學<br>資訊傳播工程學系碩士班<br>100<br>Microsoft released the Kinect in 2010. It can capture the user’s depth information and use the body to replace the traditional remote control machine, so every player can feel unprecedented entertainment experience. Kinect is reasonable and powerful, so it is attractive to a lot of developers in industry or researchers to develop innovated applications.
The Kinect sensor has the limitation in the detection angle and range. If user will want to control many appliances, every appliance must prepare its dedicated device. According to this research, it only needs one Kinect that can control many appliances. Besides, this research uses an Arduino as IR LED controller to send remote control signals to operate machine. So user can use his hands to replace the remote control at home. Therefore, Kinect and Arduino can let our life be simple.
When a user enters the sensing area, our system can detect the human skeleton by Microsoft Kinect SDK. Our system can also calculate the 3D transform to recover user''s pose. If the user raises his hand to point at an appliance, he can specify that device to power on/off and use his gestures to control it. Four gestures are also defined for the most important control signals such as forward, backward, up and down. Our system can also extend to eight gestures for extra commands including escape command. The control system, without traditional remote controller on hand, can make the appliances control easier in digital home.
