Minnet sviker Aldrig : Att utnyttja volatil data i Krypterade system
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..
Mötesanläggningarnas framgångsfaktorer : En fallstudie av Stockholmsmässan och Stockholm Waterfront Congress Centre
The aim of this essay is to examine how important marketing and networking is for the meeting industry in Stockholm. The meeting industry is one of the most profitable areas of the tourism industry today and a major contributor to economic growth in Sweden. The meeting industry has grown rapidly in Sweden and Stockholm has during the last five years been one of the ten most popular congress cities in the world. This has resulted in that the city has become a strong competitor to other European cities.Stockholm International fairs are for example the largest trade fair organizer in Scandinavia and Stockholm Waterfront Congress Centre is the new arena of opportunity.However the marketing and a broad network is necessary for meeting facilities if their aim is to be successful. Marketing contributes to the meeting facilities establishment and makes it well known for the potential market, while the collaborations and relationships is important for facilitating their work.
"ESS avgörs i Bryssel": Nätverk söker förankring i institutionell beslutsstruktur
This paper aims at describing and explaining the bi-and multilateral negotiations that are, and have been, taking place between Sweden's chief negotiator Allan Larsson and European countries, and within the EU institutions in Brussels, in order to seek support for the Swedish offer to host the European Spallation Source, ESS. It applies a case study method using political science theories ? governance and government ? and to a large extent information from the involved actors in the policy process. The paper also presents a constructive position, in showing how the negotiations on ESS can turn into a process leading to a decision on the construction of this research facility. ESS is negotiated in networks on bi- and multilateral levels consisting of European research representatives and financiers.
Virtuell hållfasthetsprovning av en turistbuss
The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

En genomtänkt introduktion : En studie om vilka faktorer och metoder som påverkar introduktionen av nyanställda på företag
The master thesis has been constructed together with Scania, who had a wish to develop their training for newly employed design engineers. The purpose of this thesis is to examine how a company's introduction process can be shaped, as the introduction is the key to success for the individual as well as the organization. With a focus on how the productivity among newly employees can increase and how the introduction becomes meaningful to the individuals and the organization, the objective of this work is to develop concepts applicable for an introduction.The work was conducted using qualitative interviews with several different individuals at Scania and other companies. Along with the interviews a survey was constructed and sent out to newly employed design engineers at Scania to get a view of their opinions on the present training. During the first period of a job there are several factors that affect the employee based on the result from the interviews, previous research and theories.
Sociala nätverkets betydelse för vägen ur hemlöshet : En narrativ studie
The aim of this study was to use stories from three people who previously lived in homelessness to increase the knowledge of the social network's impact on the process of exiting homelessness. In order to answer our questions, whether the social network facilitated or hindered the way out of homelessness, we have used a narrative method to take advantage of these person's life stories. As a theoretical perspective, we used the ecology of human development, based on the idea that human development occurs in interaction with their environment at different levels. Results showed those interviewees' networks had a significant impact on their path out of homelessness and that these relationships both facilitated and hindered this process. At the same time, these relationships affected our interviewees in different ways and were found in various areas of life, which indicates that there is more than one way out of homelessness.
Betydelsen av öppenhet, deltagande och ansvar i utformningen av megaprojekt En analys av policyprocessen kring ESS-projektet mellan 1990-2008
This thesis consists of three parts: one normative, one empirical and one constructive, with the intention to explore the enforcement of accountability in megaprojects.The thesis aims to evaluate the level of accountability in the policy process of the European Spallation Source, ESS between 1990 and 2008. In order to make a comparison possible, a norm is created concerning how a policy process should be designed, with primary focus on openness and participation, to make enforcement of accountability possible. The policy process of the ESS is compared with this norm with the purpose of discovering whether the process contains elements that assure enforcement of accountability. After the comparison is done, it is possible to formulate constructive proposals about how the enforcement of accountability can be improved.The thesis also explores how networks, consisting of actors with particular resources, surrounding the ESS-project affects the form of the policy process, e.g. in shaping the social construction of the aim and purpose of the project.

Flexibla aktörer, interna rum : Filmproducenter, personliga nätverk och mötesplatser inom filmbranschen
I denna uppsats studeras hur kontakter mellan filmproducenter och manusförfattare, regissörer och finansiärer skapas och fördjupas samt i vilka konkreta fysiska rum sådana kontakter kan ske. Djupintervjuer har gjorts med tre Stockholmsbaserade filmproducenter och två andra nyckelpersoner i samma stad. Dessa intervjuer har sedan analyserats dels hermeneutiskt, dels genom diskursanalys. Resultaten visar att kontakter ofta skapas dels genom personliga nätverk, dels i själva arbetet med filmprojekt. Mötesplatserna är ofta temporära och interna, även om vissa typer av miljöer som kontor, lägenheter och restauranger återkommer.
Ett författarskap i akademins gränsland : Stallmästare Johan Leven Ekelunds efterlämnade manuskript
Uppsala University Library owns eight volumes of manuscripts attributed to the academy equerry Johan Leven Ekelund (c.1701?1775). In this thesis, I apply methods from the field of material culture studies in order to establish which of the volumes that formed the donation from Leven to the library mentioned in his will. By mapping certain markers such as places, names and dates I am able to identify to some extent where Leven gained his practical skills and which writers influenced him. By analysing the texts, I draw the conclusion that the manuscripts can be divided into groups aimed for different audiences.
Återkallning av Meningsbärande Enheter med Hjälp av Stödord och Internet : Ett kvasiexperiment för att undersöka återkallning av semantiskt meningsbärande enheter med externa hjälpmedel
The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.
