Usability guided development of a participant database system / Användbarhetsledd utveckling av ett deltagardatabassystemFalk, Joakim January 2018 (has links)
This project consisted of the development of a web based participant database system to replace a spreadsheet based one for the project “Vi Ses! Språkvänner i Linköping” and the evaluation of it. The design and implementation was done iteratively using a collection of usability guidelines as well as the results of a set of user tests. User tests were also used for the evaluation of the web database system. The task during the user tests was participant matching and the main measurement taken was task completion time. The project resulted in a web database system that could fully replace the spreadsheet database system. The evaluation tests showed that this system was both faster to match participants in as well as less error prone. / Detta projekt bestod av utvecklingen och evalueringen av ett webbaserat databassystem för deltagare. Den skulle ersätta ett existerande Excel-baserat databassystem för projektet “Vi Ses! Språkvänner i Linköping”. Designen och implementationen gjordes iterativt med hjälp av användbarhetsriktlinjer och resultat från användartester. Användartester användes även för evalueringen av webbdatabassystemet. Uppgiften i användartesterna var deltagarmatchning och det huvudsakliga mätvärdet var hur lång tid uppgiften tog. Projektet resulterade i ett webbaserat databassystem som helt kunde ersätta det Excel-baserade systemet. Evalueringstesterna visade att systemet var både snabbare och mindre felbenäget att matcha deltagare i.

Development of high-performance algorithms for a new generation of versatile molecular descriptors. The Pentacle softwareDurán Alcaide, Ángel 04 March 2010 (has links)
The work of this thesis was focused on the development of high-performance algorithms for a new generation of molecular descriptors, with many advantages with respect to its predecessors, suitable for diverse applications in the field of drug design, as well as its implementation in commercial grade scientific software (Pentacle). As a first step, we developed a new algorithm (AMANDA) for discretizing molecular interaction fields which allows extracting from them the most interesting regions in an efficient way. This algorithm was incorporated into a new generation of alignmentindependent molecular descriptors, named GRIND-2. The computing speed and efficiency of the new algorithm allow the application of these descriptors in virtual screening. In addition, we developed a new alignment-independent encoding algorithm (CLACC) producing quantitative structure-activity relationship models which have better predictive ability and are easier to interpret than those obtained with other methods. / El trabajo que se presenta en esta tesis se ha centrado en el desarrollo de algoritmos de altas prestaciones para la obtención de una nueva generación de descriptores moleculares, con numerosas ventajas con respecto a sus predecesores, adecuados para diversas aplicaciones en el área del diseño de fármacos, y en su implementación en un programa científico de calidad comercial (Pentacle). Inicialmente se desarrolló un nuevo algoritmo de discretización de campos de interacción molecular (AMANDA) que permite extraer eficientemente las regiones de máximo interés. Este algoritmo fue incorporado en una nueva generación de descriptores moleculares independientes del alineamiento, denominados GRIND-2. La rapidez y eficiencia del nuevo algoritmo permitieron aplicar estos descriptores en cribados virtuales. Por último, se puso a punto un nuevo algoritmo de codificación independiente de alineamiento (CLACC) que permite obtener modelos cuantitativos de relación estructura-actividad con mejor capacidad predictiva y mucho más fáciles de interpretar que los obtenidos con otros métodos.
