This report describes my degree project. For my degree project I made a demo for a game idea that I've developed, and implemented for use with Xbox 360. The idea was about converting the feeling and gameplay of old 2D side-scrolling platform games into 3D, viewed from a first-person perspective. The Xbox 360 version of the demo was also submitted for the game competition Swedish Game Awards. In the report, I explain this idea more extensive, what software I used to implement it, and how I implemented it. Finally, at the end I clarify the results and discuss fulfilled tasks and future Improvements.

The purpose of this thesis is to explore and analyze the processes and efforts involved in rebuilding the war-torn state of Afghanistan. The examined period span from the fall of the Taliban regime in 2001, to the elections in 2005. This period, commonly known as the Bonn-process, sets out the initial time for the reconstruction of the state.A theoretical framework, which considers the necessary mechanisms for successful state-building, will be used to analyze Afghanistan's re-building process. The mechanisms include the prerequisite of a stable security environment, emerging from a cease-fire, together with the development of a well-functioning economy, re-introduction of rule of law and rejuvenating civil society.The failure to establish a secure environment has had a devastating impact on all analyzed aspects of the re-building process. It is therefore crucial that the international society continuing to assists the Afghan government in its efforts to strengthen its capacity, in order to improve the security situation.

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

The aim was to evaluate and suggest Improvements for the prototype TIVOLI (sign-learning via computer-based playful interaction). The game purposed to give children who need signing as augmentative and alternative communication enhanced signing skills. Three children in need of signs played TIVOLI at home during 4-5 weeks. Data contained parental interviews, Talking Mats interviews, assessment of signing competence before and after the evaluation period and game protocols. One game interaction per child was filmed.

Benchmarking is an established method of working which is often used in order to develop the quality of the organization. However, almost 70% of the organizations with benchmarking fail due to the lack of planning and structuring of the benchmarking exercise. Maintenance sections in the paper and pulp industry are one of those who have decided to conduct benchmarking. Therefore, the purpose of this study is to gain knowledge of how the maintenance sections in the paper and pulp industry deliberately structure and plan to use benchmarking as a driving force for quality development in the maintenance sections.The study is a hermeneutic case study. Telephone interviews and document analysis have been used as data acquisition methods.The results show that there is a lack of both planning and structuring in the benchmarking process, and lack of management commitment for quality Improvements within industrial maintenance.

The purpose of this study is to investigate if reconciliation between former war-enemies and ethnic groups (Muslims, Croats and Serbs) in Bosnia and Hercegovina is possible today. Reconciliation between these groups is necessary for the development of the state and sustainable peace. In order to fulfil the aim I have applied qualitative conversation interviews together with qualitative literature study.In this research I have studied the three largest parties (SDA, HDZ and SDS) in Bosnia and Herzegovina. Conversation interviews were made with two representatives of each party. The reconciliation theory and the recommendations that the theory advocates were used in the study.

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Bygglovsprocessen är en vital del i den totala byggprocessen eftersom ett bygglov är nödvändigt i nästan alla fall av nybyggnation och större renoveringar. I dagens samhälle där byggprocessen är under utveckling och allt större tidspress finns så är bygglovsprocessen ofta en flaskhals innan bygget kan påbörjas. Därför behöver bygglovsprocessen utvecklas för att bli effektivare.Syftet med denna undersökning att utreda vad tidigare kunder hos Stadsbyggnadskontoret (SBK) Göteborg anser om bygglovshanteringen. Utifrån de resultat som erhålls presenteras vilka delar i bygglovsprocessen som kan förbättras och effektiviseras. Dessutom ges förslag på förändringar för att uppnå detta.Kundundersökningen genomfördes med en enkät som skickades ut via e-post till kunder som fått godkänt bygglov i februari 2014.

The purpose of this report is to study the relationship between the rescue service fire prevention activities and the number of arson fires in schools. An objective of the project is also to investi-gate the need of developing national methods for fire prevention. The results are based on a questionnaire study among 35 fire departments and further interviews with five of them. The results indicate that there is a relationship between the rescue service fire prevention activities and the number of arson fires in schools. The relationship is positive in the sense that arson fires in schools decrease with increasing prevention activities.

The share of human beings with overweight or obesity is increasing. This has become a problem for society since obesity often leads to illness. This illness affects life negatively and often leads to depression, absence from work and medical care. One treatment against obesity is to do bariatric surgery, or Gastric bypass. The purpose of the study was to illuminate the experiences of care encompassing Gastric bypass surgery.

2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.

The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible Improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.

We were commissioned by Bulten Stainless AB to identify and analyze their customer order flow. Because the company had problems with delays in the production and deliveries to the customer, the task also included investigation of how the company work with prevention and management of delays. The purpose of the project also included to identify critical factors for effective order flow in smaller workshop companies.The information about the flow and how the work takes place within the company were collected through observations on the company and interviews with the staff. This information was used to draw maps over the customer order flow and to write a description of the current situation within the company. Both strengths and weaknesses of the companies work could be identified through analysis of the present situation.

Trioplanex International AB is a part of the group Trioplast Industrier AB, which produces packaging materials for the film and hygiene industry. The group is active throughout Europe, where most of the production is located in Sweden, with head office in Smålandsstenar. Operations in Landskrona consist of Trioplanex International AB and Trioplast Landskrona.Semi-finished articles consisting of paper cores, so called bobbins, give rise to a high amount of core waste in any form of core cutting. The objective of the report is to map out all core waste and illustrate the material flow with regard to present layout and equipment.In the beginning of the project an analysis of the current process was carried out with focus on the cutting equipment. A case study in the form of an improvement work took place in order to reduce the causes which had the biggest impact on existing machinery.Improvement proposals were discussed by the author together with supervisor, assigner and other parties involved.
