The research in this thesis attempts to understand what happens when children (3-6 years of age) interact with each other in the context of free play in two pre-school settings when adults are not involved. The aim of the study was to get a closer look at how children create relationships and how they protect and defend their interactional spaces. Data was gathered through ethnographically inspired methodology, using video observation to capture the everyday interactions of the children. Results were analyzed using a phenomenological approach to peer cultures. Previous research suggests that it is very important for children to maintain their interactions with peers and gaining access to play.

Problem solving is a big part of design, however a lot of emphasis is put on creativity in research related to the effects of stress. Research has shown that the amount of stress we feel affects idea generation. Stress may also affect the ability to solve problems, however the researchers don?t seem to agree about what the effect of stress actually does.The study was made through experimental sessions where the respondents were asked to solve 4 matchstick puzzles of similar difficulty. Depending on their outcome they experienced more or less stress.

This study aims to highlight the crisis and adjustment process in individuals who suffered myocardial infarction. The research questions focus on the informants? experiences of the crisis and life adjustment process, and illuminate the coping strategies that the informants describe important. By using a narrative method and applyingthe crisis theory and coping theory as theoretical guidelines, this study endeavors to illuminate individuals' experiences of the disease from their own perspective. The empirical material consists of four life stories gatheredthrough semi-structured interviews.

The aim of the study is to get a better understanding of leader's reactions in a crisis situation, and to examine whether locus of control and coping strategies can be related to leaders need for social support. The role of a leader in a crisis situation is complex and includes several aspects which must be illustrated to understand the leader's situation. Four leaders have participated in the study. The methods that have been used are questionnaires for measuring locus of control and coping and semi-structured interviews. The results show that search for social support cannot be seen as an outcome of a specific locus of control or coping strategy.

The project has been oriented for development of fixtures to ateljé Lyktan to provide a more efficiency line. In the year 2012 the company invested in a new coating booth, which leads to opportunities to upgrading the fixtures and also new design. The request is to minimize the area for storage of fixtures, and therefore should fixtures be designed to apply as many articles as possible The priority of products that fixtures have development to has been products that are most frequently coated and new products that don?t have any fixtures. The product families that the project has been having focus on is TIME and FOVEA with RONDO.

This is a report for a bachelor degree thesis in electronics at Umeå university. The target was to design a fully functional PCB-layout and then solder components to it. In order to do that I had to first proofread a schematic of the system to find things that were not correct and correct them. The project is a cooperation between the author and the company Calmon Stegmotorteknik. During the whole project the people at Calmon supported the author with the appropriate knowledge to complete the tasks.

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.

Användandet av mobiltelefoner har blivit en del av vår vardag i dagens samhälle. Mobiltelefonindustrin är en miljard industri med stora företag som Motorola, Nokia och Sony Eriksson. De senaste åren har det även kommit in nya aktörer på marknaden som Apple med sin iPhone och Google med sitt mobiltelefons?operativsystem Android. Dessa aktörer har kommit ut med flera nya mobiltelefonmodeller som använder sig ut av pekskärmar.

The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Webbdesign är ett hantverk med potential till oändlig variation och oräkneliga möjligheter, men det är även en process styrd av standarder och förhållningssätt för att optimera resultatet för slutanvändaren. Begrepp så som user experience och framför allt user experience design har i och med utvecklingen blivit allt viktigare aktörer inom webbdesign. Samtidigt som de underlättar i utvecklingsprocessen genom att diktera hur design bör utformas, skapar de inte också då begränsningar av potentialen för webbdesign? Antalet variationer och möjligheter minskar drastiskt när webbdesigners anpassar sig efter dessa standarder.Den här undersökningen syftar till att utveckla nya metoder och strategier för att främja innovativ webbdesign och undersöka hur modebranschens konstanta strävan efter innovation skulle kunna inspirera och kanske till och med förändra webbdesign utvecklingen. Genom att bryta ner, analysera och sammanfoga designprocesserna för haute couture och webbdesign skapas en designmetod som ger medvetenhet i designval och hjälper att ifrågasätta standarder samt att undersöka alternativa lösningar.

Den här rapporten ämnar besvara frågan om hur man bör utforma ett användargränssnitt för en mobil applikation så att antalet knapptryckningar, speciellt textinmatning, på den mobila enheten minimeras. Med mobil applikation menas i detta fall ett program avsett att köras på en mobiltelefon med en numerisk knappuppsättning. Applikationen i fråga är en resesökningsfunktion ämnad för lokal busstrafik; för testsyften används hållplatser inom Jönköpings län.Ett designkoncept utformades baserat på ett menysystem bestående av alfabetsgrupper för inmatning av namn på orter och hållplatser. Utifrån detta utvecklades en prototyp i Java Micro Edition som sedan kunde utvärderas och modifieras efter ett mindre användartest.Prototypen testades på tre personer efter en metodik som utformats på mjukvaruföretaget Apple. Resultatet visade en allvarlig brist, som lyckligtvis är enkel att korrigera.

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

The purpose of this essay is to investigate how well vision and strategies communicates from division level to underlying business unit levels with focus on the Balanced Scorecard Concept. The investigation was carried out within the ANS division and two of its underlying business units at the LFV Group (Swedish Airports and Air Navigation Services). ANS is responsible for the air navigation services in Sweden and the production of the services is carried out of the business units AER (En Route) and ATA (Tower and Approach). With Air Navigation Services means supervision and conducting air traffic mainly within national air space. The purpose of the services is to insure that air traffic could be carried out in a safe way.The Balanced Scorecard was introduced for the first time in the beginning of the 1990´s.

Enligt kommunikationsmyndigheten PTS finns det cirka 10miljoner mobiltelefonabonnemang endast i Sverige. Telefonerna innehåller operativsystem där det tillåts mängder av olika sorters program. I och med att Apple 2007 introducerade sin iPhone exploderade marknaden för så kallade Nomadic Devices. En telefon som mer är tänkt att fungera som någon form av handdator. Dessa telefoners utformning och funktioner möjliggör för utvecklare att ta fram mer avancerade program än man tidigare sett för mobiltelefoner.
