En utvärdering av verkliga scenarion utifrån ett heuristiskt perspektiv
I syfte att förbättra kunskapsläget kring människors beteenden vid bränder och utrymningar studerades fyra brandsituationer hämtade från ett flertal verkliga händelser ur ett beslutsfattande- och riskbedömningsperspektiv. Det teoretiska underlaget hämtades ur Kahnemans och …
This master’s thesis examines the possibility to heuristically optimise instruction cache performance in a Just-In-Time (JIT) compiler. Programs that do not fit inside the cache all at once may suffer from cache misses as a result of frequently executed code segments competing …
The heuristic methods used by the anti-trojan application TrojanHunter have been evaluated. The evaluation shows that the heuristic scan engine of TrojanHunter has a very good detection ratio and that the detection ratio can be even further improved by implementing the suggested …
… thesis a number of well known usability methods were used, e.g. interviews, heuristic evaluation and thinking aloud protocol. All these methods are described thoroughly in this report among with a review of how they were implemented. Finally, these methods are being discussed …
En studie av hur riskbegreppet konstrueras i den svenska kärnkraftsdebatten
… place greater trust in the existing science. Finally, the concept of an affect heuristic seems to apply to all groups, although in different sequences of influence, explaining in part recent developments of the debate.
En studie om skapandet av en tillgänglig och användbar webbplats
… the World Wide Web Consortium, as well as a number of design principles and heuristics outlined in this paper. We also conducted several usability tests on users from our intended target group. All the measures taken were an effort to ensure that Larmbolaget’s website be as …
… complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website. The system design follows SOLID principles, some pattern-design were also used because …
En undersökning av användbarhetsproblem hos Netflix? gränssnitt med hjälp av en lätt modifikation av Jacob Nielsens ”usability heuristics”
… in 10 Swedish households. This study is based on the well-established heuristic evaluation method of Jacob Nielsen, which we modified slightly by letting the users to act as ”evaluation experts” and informing them about the heuristic rules of thumb during the evaluation process …
… for the purpose of evaluating web APIs. The purpose of this essay is to adjust heuristic evaluation wich is a method originating from HCI. The adjustment will result in a presentation of evaluation criteria, suitable for evaluating web APIs. In our case study we perform an …
Heuristikers påverkan på kognitiva resurser inom konsumentpsykologi
… various mental shortcuts that we use unconsciously. These shortcuts are called heuristics. The purpose of this study is to investigate the consequences for the use of various heuristics and if they reduce the cognitive resources to varying degrees. A quantitative data collection …
En studie kring hur affect heuristic och affective imagery påverkar en individs riskbedömning
… det gick att påverka en individs riskbedömning med hjälp av teorin om affect heuristic samt hur mental visualisering kunde påverka en individs affekt i olika riktningar.Försöksdeltagarna bestod av 40 studenter vid Umeå universitet i åldrarna 19-35. De fick i en enkätundersökning …
This Master’s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case …
… permitted working hours for the truck drivers. Integer solutions are generated heuristically. Simulations that have been performed with the model reveals interesting differences concerning how the distribution is handled in different parts of Sweden. In western Sweden the …
… to a Boolean domain and performing the optimisations. The variable reduction heuristic is based on finding sub-circuits that are suitable for reduction and a state space search is performed on those groups. An evaluation of the results shows that in some cases the compiler is …
