When the use of encryption amongst the regular computer user grows morewidespread than ever it makes the life of the IT-forensics experts difficult.Hampering the judicial investigations that otherwise could have lead to convictions.In this report we will treat the subject of crypto analysis with a focus on decrypting files and devices encrypted with the software TrueCrypt. A solution will be presented that can facilitate the future work involving encryption. The application DFEAT that has been developed during the writings of this report is faster than the corresponding software EFDD, and attacks both partitions and bitwise copies of entire harddrives where PKF fails.DFEAT is a lightweight application that is almost 50 times smaller compared to EFDD and 200 times smaller than PKF's portable version..

This study is a critical discourse analysis on the genre of career coaching. Focus lies on questions such as how doescareer coaching articles construct the working subject, and how is working life described in the genre. The categoryof social relations is central to the study. I ask questions about which social relations are of importance, and whichare not, in the career coaching version of working life and how can these relations be interpreted from a critical pointof view. The concepts of power-knowledge is central to the analysis of social relations and the term employabilityconstitute the main theoretical understanding of what distinguish the contemporary labour market.

This report describes the procedure in which we accomplished our task, which was to implement a present algorithm. This was made using C++. The algorithm is developed by Sasan Gooran, who is our examiner in this project. The algorithm uses an iterative method to produce the halftoned images. The reason for this project is to speed up the existing program which is made in Matlab.

This report is about the development of a prototype of a mobile application and a web application that will help diabetes patients in their own treatment and ease diabetes nurses work with their diabetes patients. The mobile application is a digital version of a diabetes diary used by the Örebro County Council primary care to ease in diabetes treatments. The report also covers tests with users which were conducted on potential users to get some sort of feedback from groups other than customer and colleagues. Tests with users showed that there was an interest in a mobile application and it was a highly appreciated project. The web application ease diabetes nurses in their work with their diabetes patients in the way that the web application can display graphs of the patient's blood glucose level. .

This thesis deals with the problems you face as a new game developer for the mobile platform Android when developing a 3D game and presents solutions to these problems. It also explores which optimizations should be made to increase performance and how well suited for game development the Android platform is. A simple 3D game for version 2.2 of Android was developed to examine this. The conclusion was that a good game structure for Android separates logic and rendering by running these separately in different threads. Solutions to rendering and updating of game logic were presented and optimizations were implemented for performance, although fewer optimizations were needed than was anticipated.

The main purpose of the study was to collect norm data forCommunication Attitude Test for Preschool and Kindergarten Children WhoStutter (KiddyCAT) for Swedish children. Sub purposes of the study were toexamine if the results on KiddyCAT vary depending on age and gender andexamine the reliability and validity for the Swedish version of KiddyCAT. Inthe study 119 children without known stuttering, 3:1?6:11 years, fromdifferent preschools in Gothenburg city participated. Neither significantcorrelation between results on KiddyCAT and age nor a significantdifference between the genders was found.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

Vart står vi och vårat förhållande till trovärdighet i en medial värld i ständig utveckling? Hur är det med det digitala inflytandet i en analog värld? Vad händer med upplevelsen och trovärdigheten i dokumentära filmsammanhang när bilden är animerad?Med hjälp utav två informationsmässigt likvärdiga filmer undersöks hur graden av trovärdighet upplevs i en animerad dokumentär kortfilm, i förhållande till en version med fotografisk bild. Ett antal respondenter får se filmerna och svara på tillhörande frågor i en enkätundersökning vars resultat redovisas och diskuteras i en större analys. Med hjälp av undersökningens resultat avgörs huruvida frågeställningen går att besvara samt vad dess slutsats föreslås ha för betydelse i framtida forskning inom ämnet..

LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.

This exam paper has been a collaboration between the writers and System Anderson AB. The assignment was about completing a client application, running on a PDA, and a server application, running as a web service. The web service handles the communication with System Anderssons existing database. The main goal for the application is that it will be used to increase efficiency in storage management. The client application will hold functions for withdrawal, purchase, delivering and inventory.

I det här arbetet undersöks det ifall ett CMS som befinner sig på webben kan få bättre exekveringstid ifall databaskod ifrån webbapplikationen istället flyttas till databasen i form av stored procedures. Det har skapats 4 stycken testapplikationer för att testa procedurernas effektivitet jämfört med hur det fungerar originellt. Testapplikationerna skickar en slumpad text till Wordpress funktionerna som har hand om inmatningar till databasen. Textsträngarna matas då in i databasen via antingen procedurer eller databaskod i webbapplikationen beroende på vilken version av Wordpress det är. I det här arbetet förklaras varför det kan vara intressant att använda sig av stored procedures och vilka för och nackdelar det finns med dem. Resultatet av det här arbetet tyder på att det kan finnas anledningar till att använda sig av procedurer vid större projekt men kan anses som överflödigt vid mindre arbeten. .

This paper is about the use of task boards in agile system development projects. The main focus is on how digitalized versions of the task board can be of assistance during the development process. Our investigation is based on qualitative studies, with system developers of various backgrounds and professional roles, along with studies of relevant literature. The main results are that a digitized version of the task board can increase awareness for the team and be of major importance if it is accessible through the web. On the other hand negative effects of the digitalization can emerge as well.

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

I januari 2011 delades de tva? sista fria IPv4-adressblocken ut av Internet Assigned Numbers Authority (IANA) till den asiatiska Internetregistratorn Apnic (Asia Pacific Network Information Centre). Detta inneba?r att adresserna som fanns i den centrala adresspoolen nu a?r slut. Registratorn hade anso?kt om dessa adressblock eftersom det ra?der akut brist pa? Internet Protocol version 4- (IPv4-adresser) i Asien samtidigt som Internetanva?ndarna i denna del av va?rlden o?kar explosionsartat (Magnusson, 2011a).

Bakgrund och problem: Att hållbarhetsrapporternas trovärdighet påverkar intressenternasförtroende är särskilt aktuellt för företag i finansbranschen. För att hjälpa företag att uppnå störretrovärdighet i hållbarhetsredovisningar lägger GRI:s fjärde generation av riktlinjerna en stor viktpå väsentlighet i rapporternas innehåll. Det som antas möjliggöra vassare hållbarhetsrapporterenligt GRI:s G4-version är en stegvis beskrivning av hur väsentlighetsanalys ska göras. GRI:s nyaoch föregående versioner skiljer sig dock inte åt när det gäller vilka faser väsentlighetsanalysenska bestå av. Trots det finns det några svenska finansföretag som redan har försökt uppfylla G4:sstörre krav på väsentlighet eller visar en förståelse för vad övergången från redovisningen enligtGRI:s tredje generation till G4 innebär för finansföretagens hållbarhetsredovisningar.Syfte: Studien syftar till att skapa förståelse för hur GRI:s fjärde generation av riktlinjernapåverkar hållbarhetsredovisningar hos svenska finansföretag.Metod: Den kvalitativa studien genomförs med hjälp av semistrukturerade intervjuer medpersoner som på något sätt är relaterade till hållbarhetsredovisning inom sju olika svenskafinansföretag.
