Denna uppsats behandlar den nya prototypen för radiosystem som tagits fram inom projektet GTRS. Systemet jämförs med det äldre taktiska radiosystemet Radio 180 för att få fram vad som egentligen skiljer mellan dessa. Därefter behandlas Nordic Battlegroup 2011, där det utreds vilka uppgifter förbandet skall klara av och några typfall baserat på uppgifterna. Uppbyggnad och funktion för förbandets sambandssystem beskrivs också där själva kommunikationsnätet från Sverige till missionsområde avhandlas. Även de olika radioapparaterna som nyttjas och deras användningsområde behandlas.

The aim of this study was to, using previously collected data from self-declared antisocial behaviour questionnaires, examine if the crime frequency has been different between adolescents that have either been referred to two different forms of open care in social service, child and youth psychiatric inpatient care or have been sent to Homes for Specialised Supervision. The criminality frequency and the most common crimes committed were compared between the study groups and further between genders in each particular study group. Statistical significance testing was used and the results of the survey revealed that juvenile delinquents that had committed severe criminal acts were represented in all four groups. The study group with adolescents in national care was the most different from other groups. These youths seemed to have had a lower crime frequency than the other groups with the exception assault and robbery.

This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..

In this essay a pilot study on the memory of Swedish Public Service radio news is presented. 30 subjects participated in the study, which was performed during three days, 18 to 20 of November 2013. The material which formed the basis for the study consisted three newscasts of Sweden's most popular radio newscast ?Dagens eko?, which is broadcasted live at 16.45 every day in the Public Service channels SR P1 and SR P4. The subjects listened to the broadcasts each day, and their memory of them was tested the day after each broadcast.The aim of the thesis is to find out which properties of the audience that affect how much ? and what parts ? of a newscast that the audience remember.

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

The aim of this study was to look into the approach of swedish journalists towards Twitter and how they apply the media ethics when using Twitter.The method for this research was a survey answered by 371 Swedish journalists, from workplaces of various contents and geographical spread, of which 271 were users of Twitter. Our results are based on the survey and theories such as the social responsibility theory, the code of ethics for the Swedish press, radio and television, gatekeeping, normalizing twitter and the private sphere of Habermas.Our results showed that swedish journalists aim to apply the media etics in most aspects such as objectivity and gatekeeping. Also the guidelines of using twitter as a journalist, according to the respondents, mainly comes from the workplace and not the code of ethics. It also showed that the majority of the journalists were pleased with the current guidelines, or the absence of guidelines..

Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.

This report studies the possibility of using some sort of radio sender and transmitter in order to position skis lost in powder snow. It is concluded that a RF-solution on the 433 MHz frequency should be the most efficient. Different forms of directional antennas are examined and studies show that in theory the best suited is the so called ?Yagi-Uda antenna?. A solution based on using a Receive Signal Strength Indicator value together with the above mentioned directional antenna is developed.

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

ObjectiveThe objective of this study was to investigate the clinical application to use ASSR in anesthetized childrenDesignOne main ambition of the investigation was to compare hearing threshold using ABR with estimated hearing threshold using ASSR. Another aim was to examine if the duration of an ASSR measurement could be reduced by only using the frequencies 1, 2 and 4 kHz and exclude the frequency 0.5 kHz. This is a retrospective study using electrophysiological measurement from a database.ResultResults showed a high correlation between hearing threshold using ABR and estimated thresholds using ASSR, with the frequency 0.5 kHz showing a slightly lower correlation. Result also showed that the test duration was increased when using all test frequencies in ASSR-measurement compared to when 0.5kHz was excluded. ConclusionThe study showed a high correlation when comparing hearing threshold using ABR and ASSR.

The aim for this study where to investigate the frequency of cutting cracks in saw timber harvested in the storm-damaged forests in regions where the storms Hilde and Ivar hit. The idea for this work came from one of the region?s biggest actors, SCA Skog and Jämtlands district. The purpose where to find out how big proportion of the saw timber that contains cutting cracks, their financial cost in lost wood value and also give advice and suggestions on how to work against the frequency of cutting cracks. For the field-study some guidelines where used to make sure that the samples were taken under the same conditions, they were: ? The field-study must be performed under harvesting of storm-felled forest, which are horizontal/inclined trunks. ? The averaged sized tree will make it possible to harvest saw timber. ? The trunks can?t be root cut. A methodology called in Swedish ?Trissmetoden? was used because it is the most frequent used methodology in earlier performed studies and the only one that can be used I field. Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters.

This degree projekt deals with Skanska´s safety at the construction site with focus on personal safety equipment. The purpose of this dissertation is to examine how the rules of personal safety equipment are applied and experienced at Skanska´s construction sites.In October 2004 Skanska started a projekt to make the construction sites more safe. With use of a questionnaire we have made a survey at different construction sites. 80 questionaires have been handed out to Skanska´s employees in the southeast region. While they were handed out we conrolled if the employees at Skanska´s construction sites used head protection, easy visible clothing, safety shoes and identification cards.The result of the survey shows how the rules are applied.

I uppsatsen behandlas frågeställningarna: Går det finna ett gemensamt sound hos musiken som spelas i P3? Och hur ser P3:s tablå ut under en vecka? Dessa frågeställningar undersöks för att ge en bild av den musik som spelas i P3 som är Sveriges Radios ungdomskanal. Frågorna undersöks genom att utgå från tidigare forskning i ämnet, information från P3:s hemsida samt genom djupgående analyser av sju låtar från de artister som spelades mest under vecka 46 år 2010. Analyserna utformas utifrån Gunnar Ternhags gehörsbaserade analysmetod. Även Lars Lilliestams gehörsbaserade analysmetoder av rock och blues används.Analyserna presenteras först låt för låt och sedan sammanfattas likheter och skillnader hos musiken som spelas.
