Sensor Placement and Graphical User Interface for Photovoltaic Array Monitoring SystemJanuary 2012 (has links)
abstract: With increased usage of green energy, the number of photovoltaic arrays used in power generation is increasing rapidly. Many of the arrays are located at remote locations where faults that occur within the array often go unnoticed and unattended for large periods of time. Technicians sent to rectify the faults have to spend a large amount of time determining the location of the fault manually. Automated monitoring systems are needed to obtain the information about the performance of the array and detect faults. Such systems must monitor the DC side of the array in addition to the AC side to identify non catastrophic faults. This thesis focuses on two of the requirements for DC side monitoring of an automated PV array monitoring system. The first part of the thesis quantifies the advantages of obtaining higher resolution data from a PV array on detection of faults. Data for the monitoring system can be gathered for the array as a whole or from additional places within the array such as individual modules and end of strings. The fault detection rate and the false positive rates are compared for array level, string level and module level PV data. Monte Carlo simulations are performed using PV array models developed in Simulink and MATLAB for fault and no fault cases. The second part describes a graphical user interface (GUI) that can be used to visualize the PV array for module level monitoring system information. A demonstration GUI is built in MATLAB using data obtained from a PV array test facility in Tempe, AZ. Visualizations are implemented to display information about the array as a whole or individual modules and locate faults in the array. / Dissertation/Thesis / M.S. Electrical Engineering 2012

Desenvolvimento de interfaces gráficas para estatística Bayesiana aplicada à comparação mista de tratamentos / Graphical User Interface development for Bayesian Statistics applied to Mixed Treatment ComparisonMarcelo Goulart Correia 12 September 2013 (has links)
A partir dos avanços obtidos pela industria farmacêutica surgiram diversos
medicamentos para o combate de enfermidades. Esses medicamentos possuem
efeito tópico similar porém com suaves modificações em sua estrutura bioquímica,
com isso a concorrência entre as industrias farmacêuticas se torna cada vez mais
acirrada. Como forma de comparar a efetividade desses medicamentos, surgem
diversas metodologias, com o objetivo de encontrar qual seria o melhor
medicamento para uma dada situação. Uma das metodologias estudadas é a
comparação mista de tratamentos, cujo objetivo é encontrar a efetividade de
determinadas drogas em estudos e/ou ensaios clínicos que abordem, mesmo que de
maneira indireta, os medicamentos estudados. A utilização dessa metodologia é
demasiadamente complexa pois requer conhecimento de linguagens de
programação em ambientes estatísticos além do domínio sobre as metodologias
aplicadas a essa técnica. O objetivo principal desse estudo é a criação de uma
interface gráfica que facilite a utilização do MTC para usuários que não possuam
conhecimento em linguagens de programação, que seja de código aberto e
multiplataforma. A expectativa é que, com essa interface, a utilização de técnicas
mais abrangentes e avançadas seja facilitada, além disso, venha tornar o
ensinamento sobre o tema mais facilitado para pessoas que ainda não conhecem o
método / Based on the progress made by the pharmaceutical industry, several
medications have emerged to combat diseases. These drugs have similar topic
effects but with subtle changes in their biochemical structure, thus competition
between the pharmaceutical industry becomes increasingly fierce. In order to
compare the effectiveness of these drugs, appear different methodologies with the
objective of find what would be the best medicine for a given situation. One of the
methods studied is the Mixed Treatment Comparision (MTC) whose objective is to
find the effectiveness of certain drugs in studies and / or clinical trials that address,
even if indirectly, the drugs studied. The use of this methodology is too complex
because it requires knowledge of programming languages in statistical environments,
beyond the mastery of the methodologies applied to this technique. The main
objective of this study is to create a graphical user interface (GUI) that facilitates the
use of MTC for users who have no knowledge in programming languages, which is
open source and cross-platform. The expectation about this interface is that the use
of more comprehensive and advanced techniques is facilitated, moreover, make the
teaching about the topic easier for people who do not know the method

Hitta rätt - utveckling av navigationsstödWendt, Emelie January 2008 (has links)
Detta arbete har utförts i samarbete med företaget Compute och fokuserar på att utveckla navigationsstöd för webbportaler med bokningssystem. Arbetet har delats upp i tre specifika mål: (1) integrera Information Foraging Theory (IFT) och Graphical User Interface principles (GUI-principer) genom att applicera dessa vid utvecklng av navigation för webbportaler med bokningssystem (2) konkretisera hur navigering kan förbättras på en webbportal med bokningssystem, utifrån ovanstående teroier och (3) arbetet skall resultera i en lista med rekommendationer som kan tillämpas vid utveckling av navigation. För att kunna integrera IFT och GUI-principer har dessa i kombination med en teroertisk studie tillämpats vid prototyping. Prototyperna användes som verktyg för att konkretisera hur navigationen kunde förbättras på portalen. Prototyperna utvärderades och resulterade i en lista med rekommendationer. Resultaten från utvärderingen påvisade att en integrering av GUI-principer och IFT kan förbättra nvigationsförhållanden på en webbportal. Arbetes främsta bidrag är listan med rekommendationer som skall kunna tillämpas vid navigationsutveckling.

Use me and play me : Grafiskt gränssnitt med Mp3-spelare för insulindoserareKozak, Daniel January 2007 (has links)
Abstract: Typ-1 diabetes eller så kallad insulinberoende diabetes, drabbar vissa barn och tonåringar. De tvingas leva hela sina liv med att injicera insulin i sin kropp, eftersom deras egen kropp har slutat tillverka insulin på egen hand. Insulinpennan är typ-1 diabetikers medicinska redskap som de måste ha tillhands vid varje måltid. Syftet med denna studie är att utveckla och ta fram ett exempel på hur ett grafiskt gränssnitt med Mp3-spelare bör se ut i en insulindoserare som riktar sig till tonåringar. För att utreda hur gränssnitt ska utformas har kvalitativa intervjufrågor ställts till produktutvecklare, diabetessjuksköterskor och tonåringar. Vidare har också analyser gjorts på befintliga insulinpennor och Mp3-spelare. Resultatet av studien är en prototyp av en insulindoserare som simuleras i Shockwave. Prototypen har med hjälp av testerna, intervjuer och analyser resulterat i hur gränssnittet bör se ut hos en insulindoserare med Mp3-spelare. Insulindoseraren innehåller de grundläggande mekaniska funktionen som en insulinpenna besitter, nämligen dosering och injektion av insulin. Utöver detta har övriga funktioner implementerats vilka har framtagits i samband med de intervjuer som gjorts. Det är timer som talar om för patienten när det är lämpligt att ta ut nålen efter en injektion. Det finns dessutom ett minne där patienten kan se vilken tid och datum en angiven dos har injicerats. För att påminna patienten om att ta sitt insulin finns det upp till 5 programmerbara alarmtider. Mp3-spelaren i insulindoseraren tas fram genom att analysera tre Mp3-spelare. Där har strukturen på gränssnittet, funktionerna i Mp3-spelarna och styrenheten en betydande roll i utvecklingen. Det har i produktutvecklingen även tagits hänsyn till vad tonåringar anser är en tilltalande Mp3-spelare.

Previous issue date: 2010 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / Aplicações para celular estão se tornando cada vez mais complexas, bem como testá-las.
Teste de interfaces gráficas (GUI) é uma tendência atual e se faz, em geral, através da
simulação de interações do usuário. Várias técnicas são propostas, no qual, eficiência
(custo de execução) e eficácia (possibilidade de encontrar bugs) são os aspectosmais cruciais
desejados pela industria. No entanto, avaliações mais sistemáticas são necessárias
para identificar quais técnicas melhoram a eficiência e eficácia de tais aplicações. Esta
tese apresenta uma avaliação experimental de duas técnicas de testes de GUI, denominadas
de DH e BxT, que são usadas para testar aplicações de celulares com um histórico
de erros reais. Estas técnicas são executadas por um longo período de tempo (timeout de
40h, por exemplo) tentando identificar as situações críticas que levam o sistema a uma
situação inesperada, onde o sistema pode não continuar sua execução normal. Essa situação
é chamada de estado de crash. A técnicaDHjá existia e é utilizadapela industriade
software, propomos outra chamada de BxT. Em uma avaliação preliminar, comparamos
eficácia e eficiência entre DH e BxT através de uma análise descritiva. Demonstramos
que uma exploração sistemática, realizada pela BxT, é uma abordagem mais interessante
para detectar falhas em aplicativos de celulares. Com base nos resultados preliminares,
planejamos e executamos um experimento controlado para obter evidência estatística
sobre sua eficiência e eficácia. Como ambas as técnicas são limitadas por um timeout
de 40h, o experimento controlado apresenta resultados parciais e, portanto, realizamos
uma investigação mais aprofundada através da análise de sobrevivência. Tal análise permite
encontrar a probabilidade de crash de uma aplicação usando tanto DH quanto BxT.
Como experimentos controlados são onerosos, propomos uma estratégia baseada em experimentos
computacionais utilizando a linguagem PRISM e seu verificador de modelos
para poder comparar técnicas de teste de GUI, em geral, e DH e BxT em particular. No
entanto, os resultados para DH e BxT tem uma limitação: a precisão do modelo não é
estatisticamente comprovada. Assim, propomos uma estratégia que consiste em utilizar
os resultados anteriores da análise de sobrevivência para calibrar nossos modelos. Finalmente,
utilizamos esta estratégia, já com os modelos calibrados, para avaliar uma nova
técnica de teste de GUI chamada Hybrid-BxT (ou simplesmente H-BxT), que é uma
combinação de DH e BxT

A GUI Standard's Impact on Usability / Hur en GUI standard påverkar användbarhetSjöberg, Hanna, Ukus, Demet January 2001 (has links)
Designing usable Graphical User Interfaces (GUIs) is a complex process and requires at least two things: knowledge of known GUI design principles and guidelines, and knowledge of structured methods for achieving usability. The purpose of writing this thesis was to investigate whether a GUI standard increases a program's usability or not. In many cases, people who take part in GUI decisions do not consider following a standard and the decisions are often based on what is best for them. Consequently, in most of the cases, programs turn out to be inconsistent and less usable. But following a GUI standard does not necessarily guarantee usability. To carry out the investigation, the GUI of a program was deliberately manipulated. Apart from the original one, two more versions were created; one strictly according to the Microsoft Standard, and one that among other things violated the standard. To be able to compare the three GUI versions, usability testing with four test users was conducted. The result of the entire investigation showed that a GUI standard increased the usability considerably. But the result also showed that the test users found the GUI, that in some aspects violated the standard, more pleasant to use, that is to say, users' satisfaction was higher. This indicates that standards ensure consistency, which provides a sense of stability and makes the GUI familiar and predictable. But GUIs should also be tailored for and validated against the users' requirements, and this is done with structured methods for achieving usability. As a GUI designer, your knowledge of the standards is the absolute minimum requirement for developing GUIs. By knowing and understanding the standards, you will also have the knowledge of how to violate the standards in order to achieve a higher degree of usability.
