SAAB Security and defense solutions i Järfälla har ett system som används av militären för övervakning av flygplan. Systemet visar på en datorskärm en karta över Europa där flygplanen visas med markeringar från data som samlats in av radars. Då data samlas in med en låg frekvens visas ytterligare en markering som kallas målspår. Dessa målspår beräknas fram med tunga matematiska beräkningar och sköts av datorns processor.Det finns ett önskemål om att flytta dessa beräkningar till datorns Grafikkort med hjälp av OpenCL och därmed frigöra processorns resurser. OpenCL har implementerats med två olika Java bindings och prestandaskillnader mellan dessa samt de ursprungliga beräkningarna har undersökts.

För att minnas långa lösenord är det inte ovanligt att användare rekommenderas att skapa en mening som sedan sätts ihop till ett långt lösenord, en lösenordsfras.Informationsteoretiskt sett är dock ett språk väldigt begränsat och förutsägbart, varför enligt Shannons definition av informationsteori en språkriktig lösenordsfras bör vara relativt lätt att knäcka.Detta arbete riktar in sig på knäckning av språkriktiga lösenordsfraser, dels i syfte att avgöra i vilken grad det är tillrådligt att basera en lösenordspolicy på lösenordsfraser för skydd av data, dels för att allmänt tillgängliga effektiva metoder idag saknas för att knäcka så långa lösenord.Inom arbetet genererades fraser för vidare användning av tillgängliga knäckningsprogram, och språket i fraserna modelleras med hjälp av en Markov-process. I denna process byggs fraserna upp genom att det används antal observerade förekomster av följder av bokstäver eller ord i en källtext, så kallade n-gram, för att avgöra möjliga/troliga nästkommande bokstav/ord i fraserna.Arbetet visar att genom att skapa modeller över språket kan språkriktiga lösenordsfraser knäckas på ett praktiskt användbart sätt jämfört med uttömmande sökning..

Boberg at Scania CV AB. The purpose was to investigate the technical and customer oriented possibilities for the development of a transport security measure against cargo crime, which is a growing problem in Europe. The main goal was to develop a concept that is possible to implement in the Scania CV AB Fleet Management System. Another goal was to develop a security model that will be used as a tool during Scania CV AB?s future development projects of transport security concepts.The work was divided into three main parts: a background study, handling cargo crime, transport security Scania CV AB trucks and market analysis, a stakeholder investigation including a questionnaire and interviews, and a concept development session.

The purpose of this essay is to investigate what kind of motives where behind the long term decisions for the Swedish military defense in 2000 and 2004. This leads to the questions that the essay is meant to answer; 1. Were the motives behind the two decisions for the Swedish military defense of economic character or an adjustment of security and defense policy? 2. Was the parliament united in the two decisions and if they were not, why? 3.

During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

This paper presents an investigation into the relationship between inmates and staff in a high security prison in Sweden. The primary objectives are to investigate this relationship from an inmate perspective and to identify key factors that may promote or hinder rehabilitative interaction with staff. Empirical data utilized in this study consist of semi-structured interviews carried out by the authors with nine inmates currently in custody of the treatment facility within the prison and six inmates housed within the study facility. This data collection method is an extension of grounded theory and four key themes were generated from the data analysis. The first of these examines the effect of rule enforcement on prison atmosphere and subsequent staff/inmate relations.

This thesis aims to study how cybersecurity is managed and framed in the context of the growing threat landscape as a result of the Ukraine Invasion. The war in Ukraine is one of the first conflicts involving extensive cyber operations, furthermore this study is interested in how Sweden, more specifically MSB, considers global security challenges and if they can learn from the conflict in Ukraine. Through a qualitative text analysis, focusing on two reports published by MSB, the study, using securitization and framing as theoretical frameworks, seeks to answer the research question ?How has MSB changed its representation of the threat and adapted its security strategy to address the increasing threat to cybersecurity following the invasion of Ukraine??. The analysis is based on five operationalization questions to clarify whether there are indications of securitization and framing in the reports. The study also aims to identify if there is a more clear threat formulated to cybersecurity.

The purpose of this thesis is to try to find out what effect subject oriented projects like Energiutmaningen has on the teachers, with a focus on teachers? physics education. What was the experience for the teachers who participated and what effects did the project have on them. Four teachers were interviewed through qualitative interviews. From the result it showed that the most experienced teachers, who have been teaching physics for many years, gained a new perspective of their teaching, through their participation a development showed in their education.

Human rights and solidarity, as well as moral and legal responsibilities to protect people in need of refuge, seem to be principles of secondary importance within international migratory policies today. Instead, the predominant view seems to focus more and more on the protection of territorial borders, the welfare state and national identity. This international change in discourse can also be seen in the political trends of individual states. There are reasons to believe that this is a development that is also perceptible in the political rhetoric that is used in parliamentary debates, which constitute the main focus of this thesis. The aim of this study has therefore been to increase the understanding of this change in migratory policies by analyzing Swedish parliamentary debates between 1975 and 2002, using a theoretical framework focused on two different perspectives on security: First, the Copenhagen School and securitization of migration, and second, human security and human rights.

This study examines university employees? perception of their employment situation and career opportunities. By tradition, fixed term contracts are used in the Swedish research community due to dependency on insecure funding. There is a current debate that questions this use of insecure employments. The employments are said to negatively affect the university?s societal role and international competitiveness.

Allt hårdare konkurrens har medfört att det är desto viktigare att beslutsansvariga i ett företag fattar snabba och korrekta beslut. För att förbättra och effektivisera beslutsfattandet och samtidigt skapa sig fördelar i förhållande till marknadskonkurrenterna, kan beslutsansvariga använda sig av ett datalager. Datalagret kan genom enorma mängder data som är insamlade från ett stort antal olika system, generera stora fördelar för ett företag. Men detta gäller dock endast under förutsättningen att datalagret är skyddat på ett lämpligt vis. Syftet med studien är att undersöka vilka lämpliga skyddsåtgärder som kan användas för att uppnå och bibehålla ett säkert datalager.

This essay analyses how Swedish authorities implement the EU regulations on the application of social security schemes and, more specifically, when it comes to health care and sickness benefits. The research is based on a survey and several interviews and aims to answer how the lower echelons of the hierarchy work towards the implementation, what are their working conditions and how the authorities evaluate and optimize the implementation process.The general conclusion of the study is that there are several flaws in the implementation process. The results have shown that there is a lack of resources as well as of tutoring and education amongst the actors. The complexity of the regulations does also seem to have influenced the process. Finally the results have shown that the public instances do not proceed to a systematic evaluation of the implementation process which has led to a bad communication between the different actors as well as to difficulties in improving the flaws in the implementation process..

This thesis discusses the theory of securitization in relation to the issue of irregularmigration, from EU level to national level. By using discourse analysis, the purpose isto explore whether the discourse leads to practice when it comes to nationalimplementation of EU debates on return policy. The material used in this workconsists of policy documents regarding the Return Directive from the EuropeanCommission as well as the Reva Project in Swedish migration policy. The mainobjective of the Reva Project is to make the process of returning irregular immigrantsmore effective and it has been strongly criticized, both by media and public opinion.The conclusion of this case study is that even if the security rhetoric may appearstronger on the EU level, the main elements of the security discourse are stillportrayed in the implementation on the national level. Based on this analysis we canmake the presumption that discourse develops into practice in the case of returnpolicy in the EU-member state relation..

Data sets are continuously increasing within organizations. Data sets will also be in larger amounts,have shorter lifetime, is becoming more varied and holds various degrees of uncertainty. Together,these dimensions are included in the term Big Data. There is no universally accepted definition ofBig Data and how it should be used. Applications that turn out to be part of a Big Data conceptoften begin as investments in an organization in order come to new insights or create new businessperspectives.
