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.

Denna uppsats handlar om den svenska Försvarsmaktens jämställdhetsmål som har satts upp för att främja jämställdheten och på sikt få in fler kvinnor i organisationen. Mer specifikt handlar uppsatsen om hur kvinnorna inom Försvarsmakten anser att dessa jämställdhetsmål efterlevs. Uppsatsen baserar sig på intervjuer med tre kvinnliga yrkesofficerare som får ge sin syn på livet i och runt det militära samt på försvarets jämställdhetsarbete och hur det påverkar dem. Resultaten jag kommer fram till i denna uppsats är att Försvarsmakten för dessa tre kvinnor är en bra arbetsplats för dem, oavsett deras individuella livssituationer, men att det fortfarande finns en hel del att jobba på vad gäller jämställdhetsmålen..

In this report, the risk of cracking in joints and/in adjacent concrete is estimated by checking shear forces in joints and the ratio between the actual maximum principal stress ant the actual strength of the concrete. The shear force has been estimated both by simple methods as well as by two-dimensional calculations. The risk of cracking in the concrete and/or in the joints is estimated with the computer program ConStre. The restraint from a resilient foundation or rock on a young concrete construction is estimated by a simple method that is exemplified. It is shown that the restraint can be neglected in some cases.

Our time is characterized by the development of new technologies that facilitate communication between people. The need for Video Mediated Communication (VMC) is increasing because people move to other locations due to migration and global mobility. VMC provides the opportunity for millions of people around the world to ?hang out? and see each other despite the distance in between. The world is "shrinking" because of the Internet and our perception of distance is changing.VMC is becoming increasingly available, in the form of applications like Skype and MSN for mobile phones and computers, and in addition, it?s practically free.The purpose of this thesis is to render a picture of the way in which people use Skype in the private sphere.

Objective: The out-of-hospital cardiac-arrest incidence in Sweden averages about 10 000 a year. Whether the victim will survive or not is dependent upon rapid actions according to the chain of survival ? early alarm, early CPR, early defibrillation and early medical treatment. While waiting for the ambulance the victim is completely dependent on immediate help from any bystander, because early CPR improves survival rates by two-three folds. Unfortunately not all bystanders start CPR because of different reasons.

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

After World War II a rapid expansion of the Swedish health care took place. Theexpansion was realised chiefly as a development of the hospitals and was bothproduced and financed mainly within the public sector. The financing consisted to ahigh degree of government grants from the state to the county councils.During the period for this examination (1945-1955) the public responsibility for thehealth care was expanded. This was expressed in the publicly financed system forhealth insurance and the cut down in the charges that the patients had to pay for thehospital care. These changes led to some discussions on the national level but reformscould on the whole, with exception for the suggested reform of the open health care,be implemented.This case-study performed on the county council in Värmland shows that the degreeof consensus was enhanced on the regional level.

Sjöfarten är väldigt viktig i vårt moderna samhälle då större delen av det gods som transporteras i världen transporteras med hjälp av sjöfart. Ur miljösynpunkt är sjöfarten relativt bra då utsläppen i förhållande till mängden gods som transporteras är väldigt låg. Men trotts att de relativa utsläppen är låga så påverkar sjöfarten miljön rejält och ökade krav ställs hela tiden för att minska miljöpåverkan från sjöfarten.Genom ett relativt enkelt MATLAB program kan man modellera en propeller till ett fartyg där olika parametrar kan varieras. I programmet får man då ut en plot med propellerns verkningsgrad, nödvändig kraft och utvunnen kraft relativt hastigheten på fartyget. Detta gör att man kan optimera propellern till fartyget genom att ändra propellerns geometri och snabbt se vad de olika parametrarna betyder för propellerns effektivitet.Transport av bananer mellan Sydamerika och Europa sker hela året om.

In 2009 transgendered persons were included in the Swedish law against discrimination. Prior to the inclusion a commission made an investigation of the necessity of such change in the law and how it could be designed. This essay focuses on the discourses regarding gender that appear in the law and the report written by the commission. Using theories by Judith Butler and discourse analysis inspired by Norman Fairclough it identifies two main discourses regarding gender: a two gender discourse and a queer discourse. The two discourses meet in the studied material in an antagonistic way, a conflict that is solved by separating the two and making one part of the law focus on gender and one on transgender.

The Swedish Armed Forces have undergone a significant change where we have gone from recruitment through duty and replaced it with a voluntary based defence. Across Europe, countries that have undergone the same type of change demonstrate change in the quality of those recruited. The focus in this paper is how recruitment quality looks in Sweden after three years of volunteer based defence and if officers at P7 can see a change in quality on those recruited. This work aims to investigate whether soldier quality has changed from conscription recruited to voluntary recruited soldiers. The question that the work tries to answer is whether one can see a change in quality in soldiers and in that case how.The result can be summarized as one begins to see a change in recruiting quality but it is not something that is visible at the regiments.

Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.

Uppsatsen behandlar den finansiella redovisningen av avsättningar för avhjälpande av förorenings­skador. Syftet är att undersöka hur ägarkoncentrationen hänger samman med den grad av informationspublicering företag har valt kring dessa avsättningar. I studien undersöks 44 företag inom olika branscher och med olika ägandeformer. I jämförelsen mellan samtliga fallföretag konstaterar vi att det finns ett samband mellan låg ägar­­kon­centration och hög grad av informations­publicering. Vi diskuterar också hur graden av vinstsyfte kan påverka graden av informations­publicering.

Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.

No other object is in our constant possession such as the mobile phone. The smartphone has been transformed into a worldwide forum for information-rich exchanges between individuals and companies, by which this rapid access to the smartphone has created and continues to create opportunities in terms of communication. Many researchers of today undertake the challenge of studying the smartphone's role as a marketing channel, and the role of the channel is now undoubtedly central in marketing. However, as the importance of marketing communication increases and despite the fact that survey methods are exceedingly dependent on a channel to fulfill its purpose, namely carry out questionnaires, there has been surprisingly little attention to the study of the channel's role and importance when carrying out surveys. The main purpose of this paper is to investigate whether the choice of a communication channel affects the survey outcome and, if so, further investigate how survey methods differ in terms of consumers' attitude and also their perception of their privacy.
