In today's highly competitive industries, engineers are driven to not only design a better product to fulfill users' needs but also demanded to develop a product in a short time to occupy the market. With the development of data collection and visualization technology, the application of data visualization into product development to enhance the ability of better product design is a significant trend.  Data visualization becomes more and more important since it could illustrate the valuable information, such as tacit needs and patterns which hidden from data, in a communicated way to help engineers get more inspiration for the conceptual design.   It is not hard to collect data; however, the challenge is to visualize the valuable information from a large number of data concisely and intuitively. In recent years, there are some visualization techniques available for product design, while, most of them are implemented in the later stage of product development, few methods are applicable for conceptual design. Therefore, this thesis is carried out to explore appropriate visualization techniques to provide support for conceptual design.   The aim of this thesis is, in an engineering environment, to investigate ways to visualize complex data legibly and intuitively to enhance engineers’ ability for conceptual design from better understanding the current machine. In order to achieve the objective, a conceptual design case of the improvement of wheel loader fuel consumption is applied, which consisted of plenty of data sets within various parameters, to explore how to reveal the hidden information of complex data for engineers.   As the result of this thesis, a prototype contains a series of visualization techniques is proposed to demonstrate data information from a wheel loader under several visualization situations. The final prototype has the functions of visualizing different operations separately; visualizing the overall fuel consumption in one operation; cluster's patterns visualization; visualizing the impact of one variable on the whole value.

[pt] A visualização volumétrica direta (volume rendering) aplicada a dados sísmicos é uma técnica ainda emergente. Apenas recentemente alguns software comerciais tornaram-se disponíveis para a indústria de petróleo. Comparado ao método tradicional de interpretação sobre seções bidimensionais, essa técnica representa uma alternativa interessante que possibilita investigar o volume de dados na sua totalidade, dessa forma permitindo um melhor entendimento da geologia estrutural e da estratigrafia da subsuperfície. Este trabalho analisa diversos aspectos da natureza dos dados sísmicos e da forma como eles afetam os resultados obtidos pelas técnicas de visualização volumétrica direta tradicionalmente empregadas. Três aspectos são discutidos em maior detalhe: quantização das amplitudes medidas para representação digital de 8-bit, segmentação do volume e modelos de iluminação. O impacto da quantização é analisado experimentalmente utilizando diferentes algoritmos de quantização de cor adaptados para tratar com amplitudes. A quantização uniforme é selecionada pela sua simplicidade e eficiência. A segmentação dos eventos sísmicos é analisada teoricamente e verificada experimentalmente. São discutidas diversas características dos dados sísmicos que restringem o sucesso da segmentação. A validade da aplicação aos dados sísmicos de modelos de iluminação local comumente empregados em visualização volumétrica é analisada teoricamente. A estimativa dos vetores normais diretamente a partir dos valores de amplitude representa uma alternativa inadequada. Por fim, é identificada uma série de requisitos aos quais um sistema deve atender para que a visualização volumétrica de dados sísmicos seja bem sucedida. / [en] Volume rendering is an emerging technique in the field of seismic data visualization. Only recently commercial software has been made available to the oil industry. Volume rendering is particulary useful for understanding structural and stratigrafhic features present in seismic data in a more natural way than using the tradicional method of interpreting over a set of 2D slices. This work adresses several topics related to the nature of seismic data and to how they interrelate with techniques commonly used in volume redering.Special attention is given to three topics: quantization of acquired seismic amplitudes to 8-bit representations, segmentattion techiniques to highlight seismic events and use of illumination models.The quantatization effects are analyzed by appying different color quantization algorithms adapted to handle seiosmic amplitudes. Uniform quantization is selected due to its simplicity and efficiency. The segmentation of seismic events is studie theorecally and verified experimentally.Several characteristics of seismic data that prevent segmentation frombeing successful are discussed. The significance of shading obtained by applying common illumination models is studie theoretically. The estimation of normal vectors directly from amplitude values is shown to be inadequate. Finally, several basic requisites to be fulfilled by seismic data volume visualization algorithms are identified. / [es] La visualización volumétrica directa (volumen rendering) aplicada a datos sísmicos es una técnica de incipiente desarrollo.

Research on financial decision aids, systems designed to help people make financial decisions, is sparse. Previous research has often focused on the theoretical soundness of the advice that the systems provide.The original contribution of this doctoral thesis is a set of empirical studies of how non-expert people understand the advice provided by financial decision aids. Since every piece of advice must be interpreted by a receiver, the accuracy of the advice can be corrupted along the way if the receiver does not understand complicated terminology, probabilistic reasoning, or abstract concepts.The design concept resulting from the studies visualizes a unique combination of short-term and long-term variables that are usually treated as separate and not interacting with each other; loans and amortizations, insurance, retirement saving, and consumption. The aim is to visualize the consequences of different decisions and possible adverse events in terms of their effect on the user’s future consumption, rather than abstract numbers detached from the user’s lived experience.The design concept was tested and evaluated by personal finance experts and professional financial advisors, as well as students and people without financial education, who represented the target users of the system. Results indicate that the system has a learning curve, but that once users understand how to read the graph, they find it more informative than conventional financial planning tools. / <p>QC 20170809</p>

Tato práce popisuje analýzu a návrh webové aplikace určené pro tvorbu informačních dashboardů. Nejdůležitějším úkolem je nejen vizualizovat data prostřednictvím grafů, ale také zvýšit použitelnost konečného produktu a umožnit programátorům rychle přidávat nové widgety. Vizualizační nástroje pro prezentaci dat jsou analyzovány jak z historického, tak i z moderního hlediska. Velká pozornost je věnována tomu, jak lidský mozek vnímá informace. Nástroje pro tvorbu grafů (zejména knihovny jazyka JavaScript) jsou analyzovány, z čehož plyne potřeba vyvinout nástroj nový. Součástí diplomové práce je open-source knihovna pro tvorbu grafů založená na knihovnách Vue.js a D3.js.

The diploma thesis deals with automated measurement of humidity and CO2 concentration inside buildings. Results of this measurement form the input parameters for the effective management of technologies reducing the energy performance of buildings. In the introduction, the issue of indoor air quality of buildings and indicators characterizing this quality are approached. The technical part of the thesis consists of making a measuring device which contains two prototype sensors provided by Teco Inc. with online access to measured data. The measurement of relative humidity, CO2 concentration and temperature in the interior of the building with the made device is compared with commercially available devices for measuring selected parameters. For unambiguous interpretation of online data, the virtual machine with an online database is configured for the created measuring device. The possibilities of using the prepared measuring device to achieve a reduction in the energy performance of buildings are discussed in the final part.
