Fruto do desenvolvimento de pesquisa em ciência computacional, especificamente sobre a questão da interface gráfica de usuário e da interação homem-computador, bem como de um constante entrelaçamento das linguagens midiáticas com as formas expressivas da primeira metade do século citado, tiveram, com o surgimento da Internet e da World Wide Web, a tarefa de conectar o ser humano e a cultura elaborada pelo universo digital. Ao mesmo tempo a influência de recursos provenientes de meios consagrados em sua constituição, como a página retangular, o enquadramento, a perspectiva linear e a câmera subjetiva, imprimem-lhe um fator notadamente cultural, daí passarem a ser denominadas de interfaces culturais. Destacam-se dois formatos básicos pelos quais o processo comunicacional engendra interfaces: os mundos virtuais e as estruturas hipertextuais. Dentro dessa configuração de comunicação digital, a hipermídia torna-se um ambiente propício para a emergência de práticas e experimentações em novos meios, por isso enfatiza-se a formação do campo hipermidiático e uma proposta de análise da hipermídia. / Abstract: Graphic interfaces of user are intellectual technologies that came to existence during the 70þs and 80þs, resulting from the development of years of research in computers, specifically on the matter of information management and man-computer interaction. With the advent of the Internet and, especially the World Wide Web, the interfaces (of the browser and of the application) have connected human being and the culture elaborated by the digital universe. On the other hand, they receive influence of resources coming from prior means in its constitution, such as the rectangular page, the framing, the linear perspective and the subjective camera, which are reused by the design of interface in the creation of new means. With these factors they are then called cultural interfaces. Two basic formats, through which information is managed in interfaces in the digital culture, are highlighted: the virtual worlds and hypertext structures. Within that technological and cultural configuration, hypermedia becomes a favorable environment for the emergence of practices and experiments in new means, and therefore emphasizes the formation of the hypermedia field and a proposal of analysis of the hypermedia. / Mestre

Ericsson is one of the world leaders in radio network technology and are spending a lot of resources on research in this area. This produces big amounts of data and there is a desire for tools that allows the researchers to investigate and present the data in a user friendly way. This is the motivation behind Elsa GVP, Ericsson’s visualization platform, which facilitates the production of interactive visualizations. The platform handles database connections and provides a number of visual components that can be used in an interactive visualization, such as bar charts, scatter plots and maps. Although Elsa GVP certainly makes the production of an interactive visualization speedier it is still a time consuming task and requires expert knowledge. Therefore, there is a desire to make the entire process easier and more user-friendly so that any employee can construct an interactive visualization. This is the motivation behind this master thesis work whose main objective is to investigate how to reduce the amount of work required to produce an interactive visualization by providing an intuitive graphical user interface.

In this thesis, we propose a Serious Game (SG) for children with the Autism Spectrum Disorder (ASD) that builds on the concept of LEGO®-Based Therapy that is aimed at improving social and cognitive skills. The proposed SG is composed of building blocks augmented with electronic modules that connect to a computing device that provides visual feedback. We investigate the effects of using the proposed computer SG by comparing it to a non-computer block-game during two empirical studies, one following an unstructured play approach and a second one with structured play by assigning roles to the players. For the first study, the proposed system showed an improvement in social interaction, collaborative play and exercise performance, as well as a decrease in solitary play. For the second study, the proposed system showed an improvement in social interaction, positive vocalizations and exploratory behavior. There was also a marked preference towards the proposed game. Furthermore, we perceived a decrease on the assistance needed when using the proposed system during both studies. Our results suggest that the proposed system can be a useful play therapy tool aimed for young children with ASD.

This diploma thesis deals with the issue of the development of mobile thin client application which is able to manage commercial infrastructure cloud service. The introduction section provides an overview of the necessary terminology and presents the problem domain that is a subject of this thesis. Besides the project itself, of which result is the main output of this work, is also the part dedicated to research of current theses, school information resources, guidelines, recommendations and methodologies that covers topics of design and implementation of graphical user interfaces for mobile devices, especially for those that have the Android operating system installed. Information obtained on basis of the research is after used as a default knowledge base for design and implementation of the presentation layer of the previously mentioned application. The next aim of this thesis is to make analysis of requirements for new application which is being developed. The requirements are then transformed into conceptual design, to which is bound the explanation of implementation of individual application layers. UML was mainly used for the modeling of the application parts design in environment of the Sybase PowerDesigner. The programming process was performed by usage of the development environment called Eclipse SDK. Benefit of this diploma thesis lies in the possibility of reusing its concentrated knowledge resulting from the research dealing with the problems of creating GUI for mobile devices. Programmer, who is untouched in this specialization, will be able to use this part of the thesis as a critical study material which has been verified in practice. Cloud infrastructure solution providers can find there an inspiration for their own mobile thin client application.

Die vorliegende Arbeit hat die Entwicklung und Umsetzung einer graphischen Benutzeroberfläche zur Erprobung von Wechselwirkungen zwischen verschiedenen Prozessparametern beim Tiefziehen von faserbasierten Materialien, wie Papier und Karton, zum Ziel. Nach einer Recherche zum Prozess des Tiefziehens und seiner Modellierung folgt das Erarbeiten von Grundsätzen bei der Erstellung und Gestaltung von graphischen Benutzerschnittstellen. Insbesondere steht dabei die Art der Eingabe von numerischen Parametern und die Visualisierung von Informationen im Vordergrund. Bei der Erstellung des Layouts des Graphical User Interface (GUI) werden die aus der Recherche gewonnenen Erkenntnisse genutzt. Dazu werden alle Anforderungen, die an die Benutzerschnittstelle gestellt werden können, zusammengetragen. Bekannte Annahmen zur Modellierung des Tiefziehprozesses werden aus Vorarbeiten verwendet. So wird innerhalb des Programmcodes der GUI der Stempelkraftverlauf beim Tiefziehen mit seinen charakteristischen Kennwerten erzeugt. Diese Kennwerte werden in einer ausgewählten Darstellungsform auf der Oberfläche für den Nutzer anschaulich präsentiert. Ein Vergleich mit den charakteristischen Werten einer Referenz in der Darstellung erlaubt eine Aussage über die Qualität des zu produzierenden Ziehformteiles. Nach der Implementierung der GUI werden abschließend Potentiale für weiterführende Arbeiten offengelegt. / The aim of this thesis is the development and implementation of a GUI for testing interactions between different process parameters in the deep drawing of fibre based materials such as paper and cardboard. After an investigation of the process of deep drawing and its modelling, the elaboration of principles of the creation and the design of the GUI follows. The main focus concentrates in particular on the type of input of numerical parameters and the visualization of information. Based on the findings from the research, the layout of the GUI is created. To this end, all requirements that can be posed on the user interface are combined. Known assumptions for the modelling of the deep drawing process are used from reliminary work. Thus, within the program code of the interface, the punch force profile during deep drawing is generated with its characteristic values. These characteristic values are displayed in a selected presentation form on the user's surface. A comparison with the characteristic values of a reference in the presentation allows a statement about the quality of the drawing part to be produced. After the implementation of the GUI the potentials for further development are finally disclosed.

Thesis (M. Sc. (Computer Science)) -- University of Limpopo, 2021 / The task of automatic speaker recognition, wherein a system verifies or identifies speakers from a recording of their voices, has been researched for several decades. However, research in this area has been carried out largely on freely accessible speaker datasets built on languages that are well-resourced like English. This study undertakes automatic speaker recognition research focused on a low-resourced language, Sepedi. As one of the 11 official languages in South Africa, Sepedi is spoken by at least 2.8 million people. Pre-recorded voices were acquired from a speech and language national repository, namely, the National Centre for Human Language Technology (NCHLT), were we selected the Sepedi NCHLT Speech Corpus. The open-source pyAudioAnalysis python library was used to extract three types of acoustic features of speech namely, time, frequency and cepstral domain features, from the acquired speech data. The effects and compatibility of these acoustic features was investigated. It was observed that combining the three acoustic features of speech had a more significant effect than using individual features as far as speaker recognition accuracy is concerned. The study also investigated the performance of machine learning algorithms on low-resourced languages such as Sepedi. Five machine learning (ML) algorithms implemented on Scikit-learn namely, K-nearest neighbours (KNN), support vector machines (SVM), random forest (RF), logistic regression (LR), and multi-layer perceptrons (MLP) were used to train different classifier models. The GridSearchCV algorithm, also implemented on Scikit-learn, was used to deduce ideal hyper-parameters for each of the five ML algorithms. The classifier models were evaluated on recognition accuracy and the results show that the MLP classifier, with a recognition accuracy of 98%, outperforms KNN, RF, LR and SVM classifiers. A graphical user interface (GUI) is developed and the best performing classifier model, MLP, is deployed on the developed GUI intended to be used for real time speaker identification and verification tasks. Participants were recruited to the GUI performance and acceptable results were obtained
