Computer use at work has risen considerably over the past fifteen years and is currently a relatively common phenomenon when 76 percent of women and 72 percent of men using the computer in their daily work (SCB Arbetsmiljörapport 2009).According to Gulliksen and Göransson (2009), Sweden is one of the countries which are more advanced in the procurement of computer systems at work. He means that Sweden has unique opportunities and conditions for user participation in the development of computer systems, when the user has the right to influence their working environment through a law in the Work Environment Act. The paper examines the importance of user involvement in system development and the Swedish company's approach and experience of user involvement. To highlight and explore the importance of user involvement, there has been a case study in which users have been representative of the development process. The case study has been conducted on a case company where the system IST analys was in need of a new interface.

Nordic Marine Sauna AB has, since 2005, designed, manufactured and sold floating saunas. Theproduct are characterised by a well thought thru and appealing design and its high quality. Thecompany is now intending to open a new business area by starting a subsidiary, NordicSubmarine Sauna AB, which will design submerged saunas. The expected customers are leisureand conference centres as well as customers that seek an experience out of the ordinary.Due to the products technical complexity a master thesis was adverted. The task was to do aninvestigation whether such a product is technically viable.The job involved research of existing products and constructions material as well as designingthe product with CAD and FEM-programs.

Sweden has a growing proportion of children living in a multilingual environment. It is thus highly important that caretakers as well as professionals who meet these children have knowledge of multilingualism and its impact on language development. Also, an increase of referrals of multilingual children with suspected language impairment to speech and language pathology clinics is seen.The objective of this study was to investigate the linguistic ability in both Swedish and Arabic in a four year old child with suspected language impairment. A further aim was to implement an intensive intervention and evaluate the efficacy of it. Language testing in both languages showed that the boy?s greatest need was in the lexical domain.

The aim for this paper has been to examine three textbooks designed for science education in upper secondary school in order to determine whether they convey any specific attitudes regarding what is considered to be ideal knowledge within the field of biology. The main focus has been to investigate if different types of design strategies have been used to emphasize certain values or attitudes and if this proves to be the case, how is this achieved specifically?                      For this purpose I have conducted several different qualitative linguistic analyses of the textbooks. The theoretical framework for the analyses lies within the main field of critical linguistics and more specifically in the context of systemic functional linguistics. The two main language models I have chosen to use for my investigations are functional grammar and multimodal text analysis.                      My results imply amongst other things that by conducting an overall assessment of the headlines in the textbooks a fair assessment can be made of which overall attitudes the books convey.

Cache simulator is a tool to increase the understanding of a cache memory. Therefore cache memory simulation is included in the course Computer Engineering IS1200 at the Royal Institution of Technology. The purpose of this project is to develop a cache memory simulator for education. The existing MipsIt and Mips Simulator which is currently used in IS1200 has been the main source of inspiration. This resulted in the development of the cache memory simulator LMSim.

Problemområde: En del av de högskolor och universitet som har hemsidor har inte lagt så stor vikt på användbarhet då deras funktionalitet brister. Det är svårt för deras studenter att på ett så enkelt sätt som möjligt nå den information de behöver. Hypotes: ?Användbarheten på högskolornas- och universitetens hemsidor kan förbättras med hjälp av att krav ställs från studenterna.? Genomförandet: För att undersöka hypotesen har tre undersökningar gjorts. Den första var en granskning av de utvalda högskolornas och universitetens hemsidor av författarna. Undersökning nummer två gjordes med hjälp av enkäter som studenter vid de utvalda högskolorna och universiteten fick svara på.

We are in an emerging digital society where we are increasingly dependent on the mastery of IT and digital technologies to better carry out our everyday tasks. They cover everything from keeping in touch with family and friends to pay bills and declare. At the same time there are those who have not learned how to use the new technology and live their lives outside of the digital society. What happens to these people, in a society that is becoming increasingly digitized? Do they take harm by being in digital exclusion? It looks like this are issues that will not become less important as digital technology constantly changes.

During the years 2005-2007 several cases of abnormal bleeding were seen after surgery in Bengal cats on veterinary clinics and animal hospitals in Sweden. In this study we have examined if the observed bleedings are due to an inherited defect of the coagulation cascade. Ten Bengal cats were tested for activated partial thromboplastin time (P-APT-time) and one-stage protrombin time (P-PK), and nine of these cats were tested for fibrinogen quantity (P-fibrinogen). Four of the tested cats had shown signs of an abnormal bleeding after surgery, and five of the cats were genetically related to these cats. One cat had a small bleeding wound at the internal base of the right auricle.

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Denna fallstudie avser att undersöka vilka behov användarna vid Kriminalvårdsverket har av att få de hjälpfunktioner som finns i verksamhetens applikationer samlade till en och samma plats. Definitioner om hur applikationer skall vara utformade för att uppnå god användbarhet förklaras, för att senare länkas ihop med det resultat som inkommit genom en utförd enkätundersökning av användarna i verksamheten. Resultatet av enkätundersökningen tillsammans med egna och andras teorier diskuteras i slutet av uppsatsen. Det visar sig att det centrala problem som finns i verksamheten inte är direkt knutet till att man samlar användarhjälpen på en och samma plats, utan verksamheten lider av stora organisatoriska problem såsom bristande utbildning i de olika programmiljöerna, skiftande kompetens och ovilja hos användarna att utnyttja de olika applikationerna som finns i verksamheten. I uppsatsen föreslås en rad konkreta punkter att tänka på, innan arbetet med att samla användarhjälp på en och samma plats kan påbörjas.

In Sweden, lowest acceptable haemoglobin levels in blood donators are 125g/L for women and 135g/L for men for a test sample taken in the beginning of the blood donation. Levels, which are 10g/L lower, are accepted if the sample is taken after the blood donation. Earlier studies show that the haemoglobin level decreases for a person that is lying down.The two aims of this study were to examine how much the haemoglobin levels change during blood donation and to examine if the photometrical instrument Pronto-7TM shows equivalent results to that of the established method Cell-Dyn Sapphire.In the study, 120 blood donors participated. Blood samples were taken in the beginning and in the end of the donation. Analyses by Pronto-7TM were done before and after the donation.The haemoglobin level decreased significantly during the blood donation.

In today?s computerized society more and more companies choose to utilize new applications that can ease the way of handling the information. For many of us is imperative that the process as efficient as possible if one takes in consideration the size of savings that this new application can bring.The developer of the evaluated system is SYSteam AB Huskvarna and they are the ones that gave us this assignment. The application that we evaluate is SCM (Secure Connection Manager). It is already used today by big companies such as Telia and Ericsson to search for errors in telephone servers placed all over the country.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

This thesis aims to examine the possibility of understanding social change by using new institutionalism approaches on a specific case, The case, which describes the implementation of new public management reform in the Swedish health care system, is analysed from two separate new institutionalismperspectives; the tool perspective and the symbol perspective. These approaches differ from one another in the sense that the first relies on a rational choice ontology, while the latter rather refers to a sociological tradition. In the analysis, causal explanations as well as aim related explanations are presented. Formative moments such as economic stagnation, non-socialist governments and ideological isomorfism are presented as important factors behind the reformation. By using the tool perspective, the motives of the idea spreading and reformation of the Swedish health care system, are connected to a strictly rationalbasis such as cost efficiency and quality improvements.
