In modern military operations the requirements of transmitting large amounts of information have increased substantially during the last decade. This increases the demand for high-capacity radio networks. It is also very important that military decisions are made on recent and correct information and this implies that low and known delays are required. The existing military radio ommunications, within the Swedish army, do not meet the requirements for capacity and delay. We have investigated how the capacity and average delay can be improved in an Ad Hoc network with STDMA by using antenna arrays.

???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.

The aim of this paper is to illuminate and discuss the political and ideological aspects of Early Medieval Nordic music. Due to shortage of sources, this issue has been overlooked until now. Did Early Medieval Nordic music meet the requirements for political and ideological use? In what ways could music potentially be used politically and ideologically? Was music used as a political and ideological tool? This is examined by a contextual analysis combining music history and historical archaeology. The survey consists of a background account, focusing on the potential of music and some requests for political use, and three case studies, where musical reflections of societal tensions is investigated in folk music lyrics, Icelandic sagas and church art.

This thesis presents a method of making repairs in log houses. The purpose of the thesis is to use this method to exemplify crafters practical intellect. The method is based on the use of a template board to transfer the measurements onto the new log. There is a dearth of literature dealing with timber repairs, and the literature regarding using a template board for this is non-existent. The description of this method has therefore been compiled from interviews with active timber crafters.

With increasing demands from the society regarding company?s CSR - Corporate social responsibility, the perspective of accounting gets broader and covers even non-financial information to meet not only the owners? demands but also others stakeholders' requirements. Sustainability has become an important tool for creating company?s business value and a positive sustainable external image.

The purpose with the study is to see how middle managers in communal elderly care looks at the implementation of the salutogenic way of working in their operations. And how it affects the middle managers working situation. We studied which scope of actions middle managers has in the salutogenic way of working. We had previous knowledge that the salutogenic working way is an ongoing work of development in several communes, and therefore we chose to study in a profound way how this work of development affects the middle managers working situation. To reach a deeper knowledge about how the salutogenic way of working affects the middle managers working situation we conducted a qualitative study with been seven semi-structured interviews with middle managers in different geographical communes.

The new accounting standards IFRS and IAS was implemented in January 2005, the purpose was to harmonize accounting standards world wide. As a result of these new rules the real estate companies are allowed to appraise real estates assets at market value. It has long been debated whether this appraisal fulfils the requirements for relevance, reliability and comparability.The paper attends to how banks control the information given by the real estate companies in the process of credit granting. As an introduction we describe the purpose of accounting and the problematic´s about appraisals with market values. Further on there is a discussion on which factors are taken into consideration when banks grant credits.The study is built on interviews at three different commercial banks.

Gender equality and gender equality work is relevant for today's working life, and previously male-dominated occupations may be increasingly under pressure to become more equal. This paper aims to explore and understand how the firefighters at a station are experiencing gender and gender equality in rescue services.Using theories of how sex is done, how a power perspective and a structural approach can show men's and women's different conditions in an organization, and theories that are more specific to gender and change management the firefighters talk about gender and gender equality are analyzed. Essay results were collected through interviews with seven firefighters and then analyzed and interpreted with the help of theories.The analysis shows that there is a perception among the firefighters that men and women are biologically different and that required physical strength legitimizes the exclusion of women. Inequality is seen as something natural and by pursuing an active gender equality women are given unwarranted benefits. When physical strength becomes a legitimate reason for exclusion, the responsibility for gender inequality is put on women and that women don?t have what it takes.There is also a resistance against gender equality analyzed in the paper, and it's stated opposition seems to be directed against the management's way of recruiting women.

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..

Rapportens syfte: Att undersöka eventuell samvariation mellan redovisningskvalitet och betavärden, volatilitet, price/earnings samt price/sales.Metod: Jämförelseanalys där korrelationer har beräknats mellan finansiella mått och resultaten utifrån en bedömningsmodell från konsultbolaget Kanton som vi anser utgöra en valid mätning av redovisningskvalitet.Dataunderlag: Finansiell data har hämtats från Avanzas webbportal medan resultaten från Kantons granskning har nyttjats, vilken i sig utgör underlag för utmärkelsen Årets börsbolag som görs i samarbete med Aktiespararna.Resultat: Vi finner inga signifikanta samband som ligger i linje med våra ursprungliga frågeställningar. Det verkar dock finnas ett positivt variationssamband mellan betavärde och redovisningskvalitet på Mid Cap-listan.Slutsatser: Analysen förkastar våra förväntade resultat och förutom mätfel diskuterar vi potentiella orsaker som exempelvis att investerare inte tar till sig all information, att den avgörande informationen återfinns i räkenskaperna eller att redovisningen bestäms till stor grad av kapitalägare. Det kan också vara så att mer information inte alltid är positivt..

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

In the European Union and in Swedish labor law, permanent employment is the main goal for employment of workers. An exception to that rule is temporary employment. The Swedish rules relating to temporary employment have undergone several changes since the Employment Protection Act was implemented in 1974. The last reform in 2007 has received criticism by respondents for not following the Union directive on fixed-term work, which went into effect in 2001. In 2010 the European Commission opened an infringement case against Sweden, after a complaint from a Swedish employees? organization.

Utvecklingen av informationssystem utförs vanligen med hjälp av en systemutvecklingsmodell där kravhanteringsaktivitetens (Requirements Engineering ? RE-processen) syfte är att samla in och bearbeta kundens alla krav på systemet. Den slutliga produkten av RE-processen är en kravspecifikation där alla kraven gällande exempelvis systemets funktionalitet, syfte etc skall specificeras.Det är inte alltid självklart vilken information som en kravspecifikation bör innehålla då detta dokument kan för både kunden och leverantören ses som ett kvitto på vad som skall utvecklas och hur det skall gå till. Dokumentet skall nämligen fungera som ett underlag för de så kallade implementations- och designaktiviteterna i systemutvecklingsarbetet samt fungera som ett underlag för diskussion och kontrakt mellan leverantör och kund gällande utvecklingen av informationssystemet. Kravspecifikationen bör därför innehålla komplett och förståelig information så att detta dokument uppfyller sina syften.
