Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

Derome Skog AB is a purchase company whose main task is to provide Derome Timber's sawmills in Halland with timber raw material. Because of the very hard competition in the roundwood market it is important to know what kind of purchase offers are required in order to buy a valuable product from forest owners.This study aims to elucidate the crucial factors when private forest owners choose to harvest and sell their forest. As base for this study, a questionnaire has been performed with private forest owners. The result of the study shows that it is not particularly often that the timber price is the crucial factor why the forest owners choose to harvest and sell the forest products; i.e. timber, pulpwood as well as energy assortments.

Billions of children, women and men lack access to safe water supplies, whichputs the affected in both social as well as economic despair. This paper willpresent some of the conclusions leading Non Governmental Organisations suchas the UN has presented recently concerning the terms of sustainability. Much ofit is true and important, but nothing can be done without extended cooperationbetween nations worldwide to find arguments that prevent short-term thinkingand economic wealth on the behalf of future sustainability.With a growing population and an increased competition for fresh water, theworld will soon face a severe shortage of good quality water for irrigation. This isbecause the distributions rarely match the demand, neither in Australia nor inAfrica. Important to notice is the major factor that the degradation of theenvironment is not one country?s problem to solve.

A diet based on a bigger part of locally produced vegetables can contribute to decreasing environmental impact and improved health. In Gotland horticulture has increased more than in Sweden in total during the last 15 years. To investigate possibilities for development of Gotland´s horticulture, the cultivation of potato, vegetables, fruits and berries was mapped through a questionnaire among growers. Interviews and a workshop with growers and reseller were conducted to investigate the interest and prerequisites for growing new crops. In total approximately 2340 hectares of potato, vegetables, fruits and berries were grown in Gotland in 2012.

The purpose of this Master thesis is to examine theinformation use and information seeking behaviour amongpersons who actively work with information. For this study,interviews have been conducted with a group of six personswho work with information in information intensiveorganizations. The aim is to answer the following questions:What kind of information is connected to the respondents?work tasks? What is the purpose of their search forinformation? Which information sources do they use and whatkind of information sources do they demand? The theoreticalframework consists mainly of Wilsons information needs andinformation seeking model.The results of this study show that none of the respondentshad any strategic model for their work with information. Theinformation that the respondents were searching for is ofdifferent content and depends on the organization in which therespondent operates.

A lot of mine waste rock and tailings arise from all mining processes and have to be stored in an appropriate way. Tailings are deposited in impoundments retained by tailings dams. The objective of tailings dams is to retain the slurry from the mining process and in that way prevent spill into the surroundings that might be harmful for the environment. Tailings dams are often constructed as staged embankments so that construction costs and demand of materials are spread more evenly over the period of deposition.The objective of this thesis has been to compile information about and evaluate events at Swedish tailings dams and also to develop a collective database for all Swedish mining companies for all tailings dams and all events that occur at tailings dams.Information about 60 events at Swedish tailings dams has been gathered and evaluated. The evaluation has been performed by comparison between and analysis of individual parameters and also by use of a multivariate statistical method called PLS.

The change of control clause is nowadays a well used covenant in the Eurobond market, with the aims to protect bondholders in case of a leveraged buyout. This thesis intend to evaluate whether the change of control clause is a new phenomenon in the Eurobond market today and to estimate what have been the driven force for the popularity of it. The thesis found that the change of control clause already existed before and thus it is not a new phenomenon. Several factors where found though to explain the extended use of the clause today. Starting in 2005 the LBO activity increased rapidly, exposing almost every company to the risk of LBO.

Mental illness is today the leading cause of long-term sick leave and insomnia, anxiety, depression and burnout are among the most common conditions. The aim of the study was to investigate the stability of these conditions and how this is influenced by gender and age, as well as the extent to which these states are risk factors for each other. The participants were a random sample (n = 2336) from the general population in the age of 18-79 years. The results showed that stable illness was more common among women than men, and that stable illness decreased with aging. The stability itself was not affected by gender or age. Relations between the conditions were bidirectional and they constitute major risk factors for each other (odds ratios, OK = 2.37 to 6.46). The largest risk factor for a condition is, however, previous occurrence of the same problem. Previous burnout was found to be a significantly larger risk factor for future burnout than previous insomnia for future insomnia (OK = 9.63 and 5.74, respectively). The results suggest that insomnia, anxiety, depression and burnout, despite their differences, are similar regarding symptoms and underlying causes. The importance of early interventions to prevent comorbid conditions which are more complicated and more difficult to treat is emphasized..

The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.

Background: In our case study we have been studying a company that during the last seven years have tried to implement the control system Balanced Scorecard. They have during this period made three attempts. According to Kaplan and Norton, the creators of Balanced Scorecard, it should take about 16 weeks to implement a Balanced Scorecard. Purpose: Our purpose is to investigate which factors that influence the possibility to implement Balanced Scorecard. Method: We have conducted a case study where we have studied implementation at three levels in a company.

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

The purpose of this report was to compare two different options for expanding of an existing pig farm. For the time being there are low prices within the agricultural market of pig production, and it is interesting to see if it is worth expanding or not. The two different options this report is based on are: expanding from a herd with 50 sows in breeding gilt production to a herd with 100 sows in breeding gilt production (option 1), or expanding to a herd with 140 sows in breeding gilt production (option 2). The number of pregnant gilts produced per year will stay the same for both alternatives; about 300 pregnant gilts per year. The rest of the breeding gilts will be sold at a weight of 25 kg. The pigs that are not sold as breeding gilts (e.g. castrates, and female pigs that are too small or that have disorders) will be kept on the farm as growing-finishing pigs until 120 kg of live weight, and then sold to the slaughter house. By using the existing buildings, even after the expanding, the investment costs, and thereby costs for housing, were kept as low as possible.

The purpose of this essay is to compare a theoretical strategic process model with the strategic work in a Swedish bank. The reason of the comparison was to identify which key success factors that is essential in strategic implementation processes. To make this study feasible three qualitative interviews were executed and it also presents data from a quantitative survey performed by the bank. The theory of the study examines eight different parts that needs to be looked at attentively when new strategies are formulated. The results points out that the work at large correspond, nevertheless the theoretical framework points out the importance of the business mission to impregnate the whole strategic process.

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.
