To do this analysis, the author considered the social, economic, political and cultural con-texts and verified these influences on the types of transformations ob-served. From a historical perspec-tive, the most relevant factors con-tributing to the makeup of Brazilian society at the time are pointed out, with emphasis on urban society in Rio de Janeiro and the changes this group underwent. The focus is on cultural factors, mostly emphasizing the culture of material items. Inter-national influences and their conse-quences on the characteristics of equipment produced in Brazil are observed. By way of advertisement from the time, photographs, user manuals and the descriptions made by some theoriticians, the author verifies and interprets the transfor-mations and their relationship to the context in which they were made.

Sweden has the highest number of single households in the world, yet the majority of household appliances are targeted towards other groups. In a society where single households and compact living are becoming increasingly present, the need for targeted products has become more relevant. The purpose of this project was to design a product which addresses these problems, and eases the everyday life of the intended users. The project was executed using several design methods, such as analytical, observational and practical ones, including interviews with a focus group consisting of 15 people. The use of these design methods identified that the biggest sources of concern amongst the target group were those related to the drying of dishes washed by hand, which led to the development of a dish rack with built in dryers. The design of this product was based on the testing of potential technical solutions and feedback from the focus group, resulting in a kitchen appliance that is uniquely adapted to the needs of single households with limited kitchen space. This design was then presented through sketches, virtual 3D models, and a physical prototype.

Nesta dissertação apresentaremos um m´método para detecção automática da quantidade de carga adicionada em uma lavadora de roupas para que esta possa adequar o seu nível de água e ciclo de lavagem. A máquina na qual este algoritmo foi desenvolvido é uma máquina de eixo vertical (abertura na parte de cima) e utiliza um motor síncrono trapezoidal (BPM do inglês Brushless Permanent Magnet). O algoritmo que será descrito aqui utiliza uma rede neural para inferir a quantidade de carga baseado em informações disponíveis nesta m´máquina como, corrente do motor, velocidade do cesto e tensão de alimentação, entre outros, essas informações estão disponíveis na maioria dos modelos de máquinas de lavar roupas que utilizam esse tipo de motor. A utilização de um algoritmo para detectar automaticamente e de forma precisa a quantidade de roupas é muito importante, pois dessa forma evita-se o desperdício de insumos e, principalmente, água no processo de lavagem. Além disso apresentaremos os resultados que mostram a diferença entre o uso da rede neural e o método linear chamado planejamento de experimento (DOE do inglês Design of Experiments). / In this dissertation a method for automatic load size detection will be presented, so the water level and the washing cycles can be chosen by a washing machine. The machine where this algorithm was developed is a top load washing machine that uses a brushless permanent magnet motor (BPM motor). The algorithm that is going to be described here uses a neural network to deduce the load size based on information available on this machine such as, motor current, basket speed, power supply voltage and others. These signals are available on most washing machines that uses this kind of motor. The use of an algorithm that detects automatically and precisely the load amount is very important in order to avoid the waste of soap, bleach and softner and, more importantly, water during the wash task. Moreover the use of the neural network will be compared with a linear methods called DOE (design of experiment). Finally, results showing the difference between both methods are presented.

Power system harmonics and interharmonics are power quality concerns that have received a great deal of attention in recent years. These phenomena can have several adverse effects on power system operation. The main harmonic and interharmonic sources are devices based on power electronics. An emerging class of harmonic sources is comprised of power electronic-based home appliances. These appliances are dispersed throughout the low-voltage distribution system, and their collective impact can result in unacceptable levels of voltage distortion. The characterization of home appliances based on their harmonic currents is an important step toward understanding the impact of these devices. This thesis presents an evaluation of the relative severity of the harmonic currents from these devices, and the impact of the disparity of the harmonic current phase angles. Typically, the voltage supplied to each harmonic source is already distorted. This distortion causes a change of the harmonic current magnitudes (traditionally referred to as the attenuation effect). Common harmonic analysis methods cannot take this variation into account because they use a typical harmonic current source model specified by a supply voltage having little or no distortion. This thesis characterizes the harmonic attenuation effect of power electronic-based appliances. One of the findings is that harmonic amplification, rather than attenuation, can occur under credible voltage conditions. This finding had not been made previously. In order to include the harmonic attenuation/amplification in appliance modeling, a measurement-based harmonic modeling technique is proposed. One of the most economic and effective ways to mitigate harmonics in power systems is through the use of harmonic shunt passive filters. These filters can be of many topologies. Selecting these topologies is a task that, today, depends on the experience and judgment of the filter designer. An investigation is carried out on the common filter topologies, and the most cost-effective topologies for mitigating harmonics are identified. As many of the larger harmonic loads also generate interharmonics, interharmonics have become prevalent in today’s medium-voltage distribution system. Mitigation cannot be carried out until the interharmonic-source location is known. A method for interharmonic source determination is proposed and then verified through simulation and field measurement studies.

Assessing the impact of domestic low-carbon technologies on the electricity distribution network requires a detailed insight into the operation of networks and the power demands of consumers. When used on a wide-scale, low-carbon technologies, including domestic scale micro-generation, heat pumps, electric vehicles and flexible demand, will change the nature of domestic electricity use. In providing a basis for the quantification of the impact upon distribution networks, this thesis details the construction and use of a high-resolution integrated model that simulates both existing domestic electricity use and low voltage distribution networks. Electricity demand is modelled at the level of individual household appliances and is based upon surveyed occupant time-use data. This approach results in a simulation that exhibits realistic time-variant demand characteristics, in both individual dwellings, as well as, groups of dwellings together. Validation is performed against real domestic electricity use data, measured for this purpose, from dwellings in Loughborough in the East Midlands, UK. The low voltage distribution network is modelled using real network data, and the output of its simulation is validated against measured network voltages and power demands. The integrated model provides a highly detailed insight into the operation of networks at a one-minute resolution. This integrated model is the main output of this research, alongside published articles and a freely downloadable software implementation of the demand model.
