This masters thesis deals with smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.

The ordinary phone of today is not the same as it was 10 years ago. We still use them tomake phone calls and to send text messages, but the ordinary phone of today has muchmore uses, it is essentially a computer. To put into context to 10 years ago, it is a verypowerful computer, capable of processing wide array of information and presenting it tothe user. Nearly every single device today has a wireless connection, which makes everyuser connectable and able to use online services and internet at any time and place.This gives the user the possibility to integrate his or hers everyday actions with socialmedia and different search functions. Being able to search the internet for persons,restaurants, public transportation and a lot more is very useful to most.

Det här projektet omfattar utvecklingen och designen av en webbplats och en webbcommunity för organisationen Nätverket Vileda samt implementationen av ett content management system för att underhålla webbplatsen. Jag reflekterar också kring Nätverket Vileda och nätverket som ett socialt fenomen men även som en kommunikationskanal för organisationer och hur detta har förändrats och utvecklats genom de senaste hundra åren..

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

This report describes the development of a system for controlling documents. The report starts with a problem description which the company wants an intranet-based solution for. The report then continues to describe the development phase for the different parts of the system which results in a complete system. The company that wanted this system is called Orbit One and is located in Ronneby, Sweden. They have had a problem with old documents circulating in different versions and in different binders.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

The aim of this essay is to investigate the function and development of non-player characters (NPC) in the TV/computer game Dragon Age: Origins. The NPCs are analysed in order to see if their development is affected by the player character?s (PC) background and interactions. The game?s ethics is also investigated by studying how the NPCs treat the PC and what significance they give to his background and actions.The results show that the NPCs are affected by the PC?s interactions, and furthermore, that they are round characters, which is unusual in TV/computer games.

In this work we?ve been focusing on how to adjust educational computer games in order to make them suited for the educational context of upper secondary school. Our opinion and entrance to the study is that the related developers of the subject, in some ways, have failed to successfully combine and find the balance between the entertaining and pedagogical aspects in the games. Our main questions is which aspects in the games game developers need to take in consideration to satisfy the pupils, but also what qualities that is needed for them to function in their educational context. In order to do that we had to investigate the people of the target groups own perspective on what technological and social aspects in the computer games they assess as important.

När man lever i ett samhälle där användandet av mobila enheter som smartphones ökar, sker motsvarande ökning av frågan på tillgång till befintliga system i mobila enheter. Ett mobilt system kan utvecklas på olika sätt beroende på efterfrågan och kunskapsbasen hos utvecklarna. Det finns olika sorters mobila system, däribland webbaserade och plattformsspecifika system.Den här rapporten innehåller en förstudie för olika tillvägagångssätt för att skapa en mobil version av ett system. Rapporten redogör för olika tekniker som kan användas beroende på vilket system som önskas överföras, samt vilken målgruppen är. Rapporten beskriver också hur framtagandet av ett mobilt system för olika mobila plattformar har skett för ett redan befintligt system..

This paper has focused on specific aspects of the law concerning the 3rd paragraph of The Care of Young Persons Act (1990:52), LVU. The purpose of this study was to examine the prerequisite other social destructive behaviour in four cases where youths has been under compulsory institutional care because of their computer gaming. The study was composed on a legal dogmatic method and a legal sociologist perspective. The legal dogmatic method implies to examine the law and its elaboration, the legal sociologist perspective focus on the consequences and causes of the court of law. The study shows that problematic computer gaming is an increasing problem in society and that other social destructive behaviour is a wide prerequisite that need new amendment in order to ensure citizens certainty..

The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.

This thesis examines if commercial-of-the-shelf (COTS) systems meet the needs in different types of organizations. This was investigated through a case study of a COTS system. The system is built for contact centers and used in different types of organizations. Contextual inquiries with users from six different organizations were held together with interviews with stakeholders of the system. This gave an understanding for how the system is used and the needs to be met in the different organizations were recognized.

The purpose of this study is to investigate in what extension students experience that computer and videogames affect them. I have chosen to focus on the physical, mental and social affect that this activity might bring them. I have also examined how much time the students spends in front of the computer or the videogame and in which social context they play.The method I have chosen to use is a quantitative opinion poll which I used in three classes of the later junior high and I have also conducted five qualitative interviews.The conclusions I have drawn from this investigation are that computer and videogames affects teenagers both physically and mentally. Physically the affects of playing videogames mostly can be derived to the physical inactivity they expose themselves to. The students themselves did not experienced any positive physical affects from their playing.Amongst the mental affects that stood out the most I recognized the social training that online gaming provided and also the intellectual stimulation that certain games offered the player.
