Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Anestesi och intensivvårdssjuksköterskans hantering av mekanisk ventilation : - en litteraturstudie om minskning av atelektasbildning och förebyggande av komplikationer
Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis. Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis. ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.
HTML-ramverk i praktiken : En studie av HTML-ramverk från utvecklarens perspektiv
This paper aim to present a model for evaluating what we choose to call HTML-frameworks, a framework that contains a set of CSS layouts and occasionally JavaScript support, based on the characteristics of the software quality standard ISO/IEC 9126-1. The methods used to produce this model is based on a field study that involved making a web portal with the help of a HTML-framework, some relevant literature and an analysis of the framework based on the characteristics of the ISO/IEC 9126-1 standard. The result was a model based on twelve different characteristics; functionality, web browser compatibility, collaborative skills, user-friendliness, documentation, visuals, graphic layout, performance, activity, professional support, replaceability and license. This model should be viewed upon as a suggestion to what a model for choosing HTML-framework could look like, because we haven?t had the time to test it in a real situation, so further studies are needed, and we believe there could be improvements made in the objectivity of the assessments of the characteristics..

If the consumers were to gain more knowledge about the payment methods and their security, it may lead to that the they would feel more comfortable when shopping online, and do it more frequently. It is this that will be investigated in this paper.The purpose of the paper is to research if consumers believed knowledge concerning the different payment methods available on the web and their security influence the consumers trust in the payment methods.
Omedveten tankeverksamhet och beslutsfattande - en användarmanual : En studie i det omedvetnas beskaffenhet
The investigation aims to clarify to what extent non-conscious thought has efficacy in for instance decision making,and also examine some aspects of the question whether decisions are caused by free will. This is done by an analysisof new research in neuroscience, economics, the combination of the two within neuroeconomics, evolutionarytheory and especially the new theory of Unconscious thought (Nordgren & Dijksterhuis 2006), which will enjoyspecial scrutiny due to its recentness in the scientific field. A decision strategy ought to put high-level consciouscognition to use where it is most effective, and this is on a different level than the canonized one. Meta decisionmaking is decision making concerning which decisions ought to be made consciously. It is the area where the largestamount of freedom can be obtained wherein the largest amount of thought effort ought to be invested.
