Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.

This thesis is based on an assignment from a unit within an international group manufacturing industrial products. The purpose of the thesis is to analyze and suggest ways to improve the cost accounting system in use at the unit. The main source of empirical data has been interviews with employees. The theoretical framework is based on a comparison between traditional/standard costing and activity-based costing (ABC). The cost accounting system in use is described in detail and classified as a traditional/standard cost accounting system.

Health and physical exercise has a become trend in today's society and the work with health promotion has increased in organizations.

Abstract AimThe purpose of this study has been to investigate the possible differences in grades and attitudes towards further studies that can be explained by the student?s level of physical activity. The questions we wanted answers to were:- Does students in more sports-oriented programs have better grades than students in more theoretical programs?- Is there a relationship between physical activity and study-results?- Are there any differences in attitudes towards further studies for students at the different programs?- Which other variables could be affecting the students grades?Method The extent of this study has included 3 municipal schools and 6 classes (2 from each school) ? in all 119 students and 6 teachers. 3 different social sciences programs have participated ? two sports-oriented and one without any sports-oriented concentration .

Infection with the bovine lungworm - Dictyocaulus viviparus - is occasionally a problem in Swedish cattle herds. The infection could act in synergism with other infections such as Corona virus to create a poorer welfare and productivity in cattle. Studies have shown that a diagnosis can be made with both the Baermann method and with an ELISA. In Norway diagnosis of BVDV on a herd level is attained through pooled serum samples. The question was raised whether pooled serum samples could be used in a similar fashion to attain status on a herd level for lungworm.

The purpose of this study was to examine health promotion and ill-health prevention in the workplaces of the City District Committees in the City of Malmö. More specifically, we wanted to find what types of health problems there were and what kinds of strategies were applied to prevent them. Furthermore, the aim was to examine whether the leaders of the City of Malmö saw any effects of the strategies in use and if so, which. Finally, the intention was to compare our empirical results to previous research in the field of health promotion and ill-health prevention in workplaces. We conducted a qualitative study consisting of semi-structured interviews with five leaders in different levels, two personnel secretaries, two employees assigned to improve the health of the personnel in the City Districts, and one safety representative.

The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).

Common wisdom dictates that because payment of dividends decreases funds available for investment, a high payout ratio is to be associated with low earnings growth. This notion has been challenged in recent years by empirical research that has found a positive relationship between payout ratio and future earnings growth, both on the aggregated market level and the company level in different countries. This study investigated the aforementioned relationship on the Swedish market by statistically analyzing future earnings growth as a function of payout ratio on a large sample of publicly listed companies over the period 1980 to 2011. The results are in line with those found in previous research and indicate that companies with high dividend payout ratio tend to experience strong future earnings growth. The results are robust to the presence of mean reversion, the use of an alternative accounting measure of earnings, non-symmetrical earnings growth cycles and alternative practices for dealing with outliers..

For many companies, the Internet has revolutionized the relationship they have with their customers concerning costumer service. The use of Information Technology in regard to Internet as a media has provided companies with the opportunity to build customer databases in order to target their customers individually.
