Esses sistemas são utilizados por pessoas que necessitam de informações navegacionais para alcançarem seus destinos. Entretanto, em muitos casos, são fornecidas apenas a localização do veículo no visor dos sistemas e setas de direção. Diferentes estudos realizados nos EUA, Inglaterra, Japão e Suécia, buscam analisar quais informações os motoristas selecionam do ambiente urbano a partir de sua memória, para assim indicar e conceber sistemas de navegação com informações que auxiliem os motoristas em sua navegação. Esses estudos apontam que o mapa cognitivo dos motoristas é a melhor fonte de informações de guia de rota, pois possui as informações realmente úteis para auxiliar a navegação em automóveis, o que indica ser necessário conhecer as representações internas do ambiente dos motoristas, para assim conceber sistemas que propiciem maior eficiência navegacional. Desse modo, esta dissertação de mestrado objetivou investigar quais aspectos do ambiente os motoristas utilizam durante a navegação. Para tanto, aplico-se o método de esboço cartográfico para seleção de informação de guia de rota em automóvel. No desenvolvimento do método desse estudo participaram 50 (cinquenta) motoristas... / The presence and use of navigation systems in cars in the world is currently increasing. These systems are used by people in need of navigational information to reach their destinations. However, in many cases, are given only the vehicle's location on the systems display and directional arrows. Different studies indicate that the cognitive map of the drivers is the best source of information for route guidance, it has the really useful information to aid navigation in cars, which indicates the need to understand the internal representations of the environment of motorists, so as to conceive systems that provide navigational efficiency. Thus, this dissertation aims to investigate which environmental aspects drivers use when navigate. For that, were applied the method of sketch map for selection of route guidance information in car. In developing the method of this study involved fifty (50) drivers (undergraduate students, postgraduate students and taxi drivers) familiar with ...

In many fields, there is a need for quick analysis of data. As the number of devices connected to the Internet grows, so does the amounts of data generated. The traditional way of analyzing large amounts of data has been by using batch processing, where the already collected data is pro-cessed. This process is time consuming, resulting in another trend emerg-ing: stream processing. Stream processing is when data is processed and stored as it arrives. Because of the velocity, volume and variations in data. Stream processing is best carried out in the main memory, and means processing and storing data as it arrives, which makes it a big challenge. This thesis focuses on developing a framework for the processing and storing of streaming temporal data enabling the data to be analyzed in real time. For this purpose, a server application was created consisting of approximate in-memory data synopsizes, called sketches, to process and store the input data. Furthermore, a client web application was created to query and analyze the data. The results show that the framework can sup-port simple aggregate queries with constant query time regardless to the volume of data. Also, it can process data 6.8 times faster than a traditional database system. All this implies that the system is scalable, at the same time it with a query error vs. memory trade-off. For a distribution of ~3000000 unique items it was concluded that the framework can provide very accurate answers, with an error rate less than 1.1%, for the trendiest data using about 100 times less space than the actual size of the data set.

O processo de refinamento de solução se traduz em um ciclo composto pela interação entre o plano mental do projetista e a realidade, com inter-relação entre os momentos de idealização, criação e percepção. A utilização do denominado “repertório” do projetista, as condições de formação acadêmica e de vivência que auxiliam o projetista na ampliação e renovação do seu repertório pessoal e na anterior apreensão e percepção do ambiente são fatores que serão levantados durante a análise para fomentar o diagnóstico. Delimita-se o escopo do presente estudo os esboços na fase de concepção de propostas, ou seja, nos períodos iniciais de criação. A metodologia proposta para tanto é moldada conforme as necessidades e a pertinência a fim de diagnosticar o esboço. Inicialmente o esboço passa pela decomposição em camadas de linguagens – semântica, gráfica e analítica –, em seguida a decomposição da linguagem gráfica – tipologias de desenho, aplicação do desenho e vocabulário –, e a avaliação bidimensional. A formulação de um exercício aplicado para levantamento de dados dos participantes e de esboços para análise. Os resultados validam a utilização do quadro de análises enquanto método analítico. / It is up to the graphic representation, a materialization of the ideas of the designer, so that they distribute themselves in forms and proportions. The process of solution refinement and translation into a cycle of danger for the interaction between the designer's mental plane and reality, with an interrelationship between the moments of idealization, creation and perception. The use of the so-called "repertoire" of the designer as conditions of academic training and experience that help the designer in the expansion and renewal of his personal repertoire and in the previous apprehension and perception of the environment are factors that are raised during an analysis to promote the diagnosis. The scope of the present study is limited to the sketches at the proposal design stage, in the initial creation periods. A methodology proposed for both is shaped according to needs and pertinence in order to diagnose the sketch. Initially the sketch goes through the decomposition of language layers - semantics, graph and analytics - into a decomposition of the graphic language - typologies of drawing, application of the drawing and vocabulary - and a two-dimensional evaluation. An exercise formulation for collecting participant data and sketches for analysis. The results are valid for the use of the analytical framework, analytical method.

Nathaniel Hawthorne's sketches, as distinguished from his tales, fall into three main types: the essay-sketch, the sketch-proper, and the vignette-sketch. A definition of these works includes a brief discussion of their inception, source, and development, and a study of the individual pieces as representative of types within each of the three main divisions. A consideration of the sketches from their inception through their final form reveals a great deal of the formative process of some of Hawthorne's ideas of literature and of the development of specific techniques to cope with his themes. A study of the sketches as a group and individually provides a clearer basis for a study of Hawthorne's other works.

Tens of thousands of years ago, humans drew sketches that we can see and identify even today. Sketches are the oldest recorded form of human communication and are still widely used. The universality of sketches supersedes that of culture and language. Despite the universal accessibility of sketches by humans, computers are unable to interpret or even correctly identify the contents of sketches drawn by humans with a practical level of accuracy. In my thesis, I demonstrate that the accuracy of existing sketch recognition techniques can be improved by optimizing the classification criteria. Current techniques classify a 20,000 sketch crowd-sourced dataset with 56% accuracy. I classify the same dataset with 52% accuracy, but identify factors that have the greatest effect on the accuracy. The ability for computers to identify human sketches would be useful particularly in pictionary-like games and other kinds of human-computer interaction; the concepts from sketch recognition could be extended to other kinds of object recognition.

Through translations and transformations, my degree project aims to explore what makes something – space, or an object– charged. I am investigating ways to create objects with the starting point in two pieces of furniture, analyzing them both in their everyday contexts, and in certain works of art. This has resulted in the creation of two works that I have called an imprint and a bench and a bed. The quality that I have been searching for in this project is what activates a subjective feeling of recognition that will stay in the mind of the beholder, a charge in an object that affects memory or consciousness. The way I explore this quality is by analyzing the terms Eros and punctum and by investigating the relationship between the abstract and the figurative, examining the bodily connection to the objects and the surrounding.

To examine how awareness of death (cues) influences believers with implicit and explicit images of Jesus with terror management theory. Previous research has found with terror management theory (TMT), that a persons view of their God provides an understanding of their worldviews and motivations. There is much evidence to suggest that character assessments, or individual differences in personality, are closely tied to people’s facial appearance and their trustworthiness. In this study using TMT, we are able to relate death thoughts to their visual perceptions of Jesus. In over 30 years, empirical research has demonstrated that reminders of morality leads people to defend their worldviews. The purpose of this research was to understand if specific words alluding to death would change how Christian individuals mentally see their Christ in comparison with no priming. We specifically have hypothesized that people who were reminded of death words would illustrate a more positive, empathetic Christ and a more neutral Christ with the lack of priming.

We present SetPad, a new application prototype that lets computer science students explore discrete math problems by sketching set expressions using pen-based input. Students can manipulate the expressions interactively with the tool via pen or multi-touch interface. Likewise, discrete mathematics instructors can use SetPad to display and work through set problems via a projector to better demonstrate the solutions to the students. We discuss the implementation and feature set of the application, as well as results from both an informal perceived usefulness evaluation for students taking a computer science foundation exam in addition to a formal user study measuring the effectiveness of the tool when solving set proof problems. The results indicate that SetPad was well received, allows for efficient solutions to proof problems, and has the potential to have a positive impact when used as as an individual student application or an instructional tool.
