As the companies of today are good at protecting themselves against external threats, but are having problems with internal threats, we focused on how information can be protected from ending up in the wrong hands. First and foremost to protect information from employees who might steal it and sell it to another company. Since the security investments needed are connected to the financial costs of implementing them we have tried to create a balance between the investments needed and the cost of implementing them. The different kinds of protection needed are first and foremost protection to make data less accessable, passwords and traceability. While it is hard for us to estimate the amount of money a company lose by the hour when the production stands still, we have not been able to use any of the excising models to calculate the profit of installing countermeasures.

When a child is hospitalized, it is usually more than one person who needs attention ? i.e. the child as well as its parents. The emergency ward environment and surgery rooms are unfamiliar and the parents feel anxious, insecure and uncertain about how to act. They are expected to participate in the child?s care, cope with their own anxiety and simultaneously convey a sense of security and stability to the child.

Målet med detta arbete är att utveckla och utvärdera ett shadergrafsystem med stöd för ?era shaderspråk. Fokus ligger på implementationen av en prototyp och hur dess delar fungerar. Prototypen utvärderas med hjälp av ett par experiment för att se hur användbart systemet för datorspel. Experimenten visar att systemet kan användas istället för traditionellt handskrivna shaders och på så vis avlasta programmerare och ge mer kontroll till gra?ker..

This paper was made together withTechPay AB, by their request.The dissertation has been divided into two separate parts; one of which is fully theoretical, with the focus on the security requirements of a digital cash register, and how to meet these requirements.The second part covers the implementation of anAndroid-oriented Java-library,created with help from the security requirements found in the first part. The purpose of this library is to make it easier to develop a cash register that uses payment terminals from TechPay.This paper also covers different communication protocols, encryption techniques and recommendations from authorities, banks and Android. This paper also contains a small review of how users are validated in applications on the current market that handles money transactions..

This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

The aim of this study is to analyze the process of an agenda setting and see how a specific issue came to materialize on the security policy agenda. The empirical goal of the study is to see why Sweden chose to participate in the EU-led operation to Chad, and how that process came to be? The analysis is based upon Kingdon's multiple streams theory (2003) where he distinguishes the process into three streams. Central for his theory is the coupling of these streams and the importance of a policy entrepreneur. I complement Kingdon's theory of policy entrepreneurs by taking inspiration from Hinnfors (1995), Gustavsson (1999) and especially Eriksson (2000) and their analysis of policy change and agenda setting.

This study examines which socially constructed threats and subjects of security existed during the aftermath of the terrorist attacks in Stockholm 2010. With ideas of identity and difference as a starting point the theoretical framework is then developed with ideas from the new critical security studies including key subjects such as attributes, risk, imaging and visualisation. The study will be executed with the use of a discourse analysis approach using newspaper articles and chronicles as the principal empirical material. The analysis will then follow two separate themes. Firstly, the different threats and subjects of security will be deduced, and also, how these social constructions inevitably create each other and require each other to continue existing.

The public administration and its officials have a number of values which they have to relate to in their work. The values are a set of democratic and economic values.This study?s purpose is to examine how the officials at the National Insurance Office in Sweden give priority to these values. The study is performed by interviews with officials at two insurance offices.The study shows that the officials in a high degree value the democratic values legal security and public ethics. In turn they experience that productivity, which is an economic value, is being promoted in a high degree from the management.

Starting at the end of the Cold War, this publication assesses the impact of the upheavals in Eastern Europe and the atrophic Soviet Union on the Swedish doctrine of neutrality with its 200 year old tradition. Since the end of world war two the proximity of the Soviet Union had constituted the major impetus for upholding a position of neutrality and as this vanished a pressure for change was created. This essay works with a theoretical framework delineated by Kjell Goldmann and under this disposition, the Swedish tradition of neutrality, governmental positions, opposition and four major influential newspapers are studied. The standings of each variable are canvassed in an attempt to explain the development of Swedish security policy during the crucial years of 1988-1992..

The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..

The purpose of this work is to raise ideas and interest for land that is very much forgotten,unused and neglected in terms of maintenance and usability. Railroads are often seen as adirty and loud intrusion in the landscape and therefore cities turn their backs on them. Theland around railroads is not considered useful despite its often central location and scrublandis common in these areas.The starting point of this work is the restrictions and possibilities linked to the land withinthe security distance 30 meters from the railroad center. Within this security distance thereare numerous limitations and regulations due to the nature of railroad use. These limitationsare counted for in the initial chapter and lay the foundation for the rest of the work.

The main purpose of this study is to examine and gain increased knowledge concerning the legal security of children taken into protective care. The purpose is also to enable contemporary social workers to reflect around phenomena in today´s social work, among other things how investigations are carried out surrounding children taken into protective care thought this historical study. To find out how social workers dealt with caretakings I have chosen to examine the personel files that the social workers compiled for each child and also interview a man who worked as a social worker at the time of the investigation. The paper is divided into two part studies were the first one studies legal security through Mattsson´s (2002) further development of KjÆnstad?s way to analyse legal security, namely through investigating the clarity of the law, procedural rules and the comtetenay of the social workers.

The flexibility of the labour market is considered as an instrument for increasing economic growth.Therefore has the use of flexible employment, also called atypical employment, increased. The atypical employment is characterized by insecurity in comparison with a traditional permanent full- time employment. One of the most common atypical employments is the manning employment, which is insecure whether it is permanent or not. The insecurity in the industry is based on insecure income, unpredictable working hours and poor psychosocial work environment.In order to encourage a continued increase of flexibility in the labour market while the need for security for staffing employees would be satisfied was Directive 2008:104 adopted. A certain amount of security has been achieved.

This report is the result of a sub-project of a larger project to create a platform formathematical education. The sub-project focuses on authentication with associ-ated security, where security is emphasized. The project environment is Java EE 6where GlassFish 4.0 acts as the server. The project has been divided into threeparts; password encryption, Java EE authentication and brute force attack. Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash algorithms is suitable fordirect use.

Internet Service Providers (ISP) har på senare år etablerat ett ökat antal Wi-Fi Hotspots på publika platser för att erbjuda Internettjänster så som e-post, Web och andra Internet-baserade program, till resande användare. Exempel på dessa platser är flygplatser, skolor, parker och städer. Växjö universitet har valt att bygga etttrådlöst nätverk på campus som man ska påbörja under sommaren 2005. Uppsatsen tar upp detta som fallstudie för diskussion av ämnet..
