This master thesis work was done by two students at Machine Design at KTH for Lesjöfors Stockholmsfjäder AB. The task was to develop a calculation program for gas springs. The program is going to ease the selection of gas springs for a given case of a lid that should be opened. The program is going to be used internal by sales people at Lesjöfors AB in Sweden and internationally. The program is therefore written in English.The program was developed in Microsoft Visual C# 2008 Express Edition.

In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

Denna kvalitativa studie behandlar matematiska uttryck hos förskolebarn. Syftet med studien är att undersöka och beskriva flickors och pojkars matematiska uttryck i förskolan samt vilka eventuella skillnader som kan iakttas i deras uttryckssätt. Detta mot bakgrund av att matematiken har fått ett allt större utrymme i förskolans verksamhet efter att förskolan fick sin första läroplan, Lpfö 98, med uttalade mål att sträva mot. Tidigare forskning visar att pedagoger bemöter flickor och pojkar olika i förskolan. Kan det ha att göra med att de uttrycker sig olika? Med detta som grund ville vi undersöka om det finns skillnader i flickors och pojkars matematiska uttryck.Matematik är ett språk och barn i förskolan utvecklar matematisk förståelse genom upplevelser i lek och sociala sammanhang.

AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

Denna studie syftar till att undersöka i vilka spontana lektyper inomhus, förskolebarn uttrycker matematiska begrepp. Bakgrunden till studien är att vi anser att matematikarbetet på förskolan ska utgå från barnens perspektiv och då har leken en viktig betydelse. Leken ses som en central del för matematiklärandet och begreppsbildningen och därför är förskolan en lämplig plats för denna studie. Om barnen redan på förskolan skapar ett intresse och börjar använda matematiska begrepp gynnar det även den begreppsanvändning som krävs i skolan. Med inspiration av ett etnografiskt förhållningssätt har det genomförts observationer på två förskoleavdelningar, vid sju tillfällen på varje avdelning.

Vi har också avsett att undersöka hur åtgärderna följer dagens matematikdidaktiska forskning, hur de följer kursplanen i matematik samt hur de följer Skolverkets riktlinjer för upprättande av åtgärdsprogram och IUP.

This report describes an examination project made for the IT consultingcompany Sogeti. The purpose of the project was to develop and modify the translation tool Language Manager (LM) built by Sogeti to be used for translating applications. Employees at Sogeti considered some disadvantages with Language Manager, version 1.0 which among others was that language files for projects were saved at two locations. Partly in resource maps among with the source code of the applications and partly in a database. This was dual work for employees at Sogeti and it also caused redundancy inthe system.

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices.

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications.

In 2011, I and fellow student at Gotland University created a multimedia game. To fit the time constraints a ?vertical slice? was created. This means a small sample of the game is taken which allows the user to understand how the game works, and at the same time, get a visual demonstration of how the game is designed. The goal of the project was to create a narrative for stadium games in which the backstory is told as players interact with their surroundings.

Syftet med undersökningen är att ta reda på vilka matematiska förmågor enligt Krutetskiis teori som synliggörs hos elever i skolår 5 som arbetar gruppvis med problemlösning. Dessutom undersöktes vad läraren uppmärksammar som matematisk förmåga och hur läraren organiserar sin undervisning för att utveckla matematisk förmåga. Krutetskii (1976) har definierat de matematiska förmågorna genom en studie som gjordes 1955-1966. Dessa tolkades och analyserades från en översatt version av hans verk. Med inspelat material från två observationer synliggjordes flera matematiska förmågor hos eleverna.

Research reports as PISA and PIRLS show that reading comprehension among Swedish students have deteriorated in recent years and that girls have better reading comprehension than boys. The basis for this study is Maj-Gun Johansson's reading comprehension test done during the four years between the years 2005-2008 in the seventh grade in a municipality in Sweden. The main purpose of this study is to examine reading literacy in terms of the influence of content and form of texts viewed from a gender perspective. The study is divided into two parts. The first part is a survey on local reading comprehension compared with results from a similar national text.

ABSTRAKT Cremona, Eva och Jägerdén, Calle (2009) Matte på lätt svenska är svårt - en studie om andraspråkselever och matematiska textuppgifter. Maths in simple Swedish is difficult, A study of second-language students and textual mathematical exercises. Skolutveckling och ledarskap, Specialpedagogisk påbyggnadsutbildning, Lärarutbildningen, Malmö högskola Syftet med studien var att undersöka vilken betydelse den språkliga formuleringen har för andraspråkselevers resultat i matematik. I examensarbetet redovisas hur dagens forskning ser på andraspråkselevers situation och vil-ka hinder som kan finnas för att dessa ska nå framgång i skolan. Hur skolornas organisation bidrar till studieresultaten samt betydelsen av modersmålsundervisning tas också upp. Studi-en genomfördes i fyra kommuner och eleverna som deltog gick på IVIK - Individuella pro-grammets introduktionskurser för invandrare. Efter en förstudie, där hemspråkslärare och elever intervjuades, genomfördes en kvantitativ enkätundersökning.
