This thesis describes the evaluation of a prototype (Illustrator) for future simulator training of Within Visual Range - combat in the Swedish Air Force. The main focus was to collect and transform user acceptance data (expert opinions) to useful guidelines for continued development. Thirteen active fighter pilots participated in the study. The aim was to use expert opinion to study a) the psychological user acceptance, and b) the technical user acceptance, of the Illustrator together with c) gathering opinions for future improvement. Three psychological aspects were rated before and after the sessions to measure psychological user acceptance.
Utvecklingen för e-auktioner inom fordonsindustrin
Syfte: Syftet med denna uppsats är att analysera utvecklingen av användandet av elektroniska business-to-business auktioner, utifrån ett kundperspektiv i fordonsbranschen. Metod: Denna uppsats präglas av den kvalitativa metoden, för att därigenom ge en ökad förståelse kring utvecklingen av användandet av e-auktioner. Inledningsvis har en litteraturstudie genomförts, varpå intervjuer med representanter för företag i fordonsbranschen gjorts. Slutsatser: Som utgångspunkt har vi valt uppskattningen att e-auktioner skall motsvara 25 procent av den elektroniska B2B-handeln i fordonsindustrin 2002. Det råder en övertygelse om att en betydande missräkning gjorts.
Mörkerkörning: Realtidssimulering och visualisering av fordonsbelysning för mörkerkörning i körsimulator
To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.
Externa kostnader för viltolyckor
The objective of this paper is to estimate monetary and non-monetary costs for the huntercaused by deer-vehicle collisions in Sweden. These costs include losses in hunting value as wellas time and money efforts related to the handling of wildlife casualties. The calculations arebased on available statistics from 2004 on deer-vehicle collisions involving moose, deer, roedeerand wild boar and on telephone interviews with hunters involved in the tracking of injuredanimals. Altogether, the annual loss in hunting value for moose was assessed to approximately30 million SEK based on the 2004 accident statistics. For roe-deer and fallow deer, thecorresponding figure was approximately 56 million SEK and 1.2 million SEK, while wild boaraccounted for 1.3 million SEK, respectively.

Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.
Ingen liten lort? : En textanalys om manlighet i Värnpliktsnytt åren 1971-1991
This essay examines masculinity in the Swedish military paper Värnpliktsnytt during 1971-1991. The purpose is to study the masculine norms and the hegemonic masculinity that Värnpliktsnytt conveys during these years. Värnpliktsnytt was handed out for free to all soldiers during 1971-2010.During the 1970?s the women were only allowed on non-combat posts and in the 1980?s they more and more were included and accepted as soldiers and staff in the military. In 1989 women were allowed to apply for active and non-combat duty in all military sectors.
Människohandel som en säkerhetsfråga
The purpose of this study is to examine which security approach dominates Sweden?s strategy for combating human trafficking. The two approaches covered in this essay are the state- centred perspective, and the individual-centred perspective. These approaches are being used because those two approaches are on each end of the security spectrum, and it is important to discover from what approach Sweden is working. This is important because it might help us to get a bigger understanding on why certain policies are being made.
Analys och jämförelse av SEAD-förmågorna hos JAS 39 Gripen samt en svensk UCAV år 2015
Syftet med denna uppsats är att jämföra/analysera förmågorna till Suppression of Enemy Air Defences (SEAD) hosJAS 39 och en svensk UCAV år 2015. Årtalet 2015 är valt för att flera bedömare anser att det är först vid dennatidpunkt som en Unmanned Combat Air Vehicle (UCAV) har en utvecklingsnivå som tillåter att de sätts in i SEADuppdrag.I uppsatsen redovisas vilka krav som ställs på en plattforms sensorer och bekämpningsförmåga för attgenomföra ett SEAD-uppdrag mot två utvalda typer av mål. Därefter sker en jämförelse mellan de båda farkosternasförmåga att detektera respektive bekämpa de båda målen. Resultatet visar att JAS 39 som bemannad plattform har enfördel i de fall då operationer är hårt styrda av Rules of Engagement (ROE), särskilt gäller detta vid fredsbevarandeoperationer. Uppsatsen visar även att flygplanradarns förmåga att upptäcka och identifiera markmål är beroende avinförandet av en SAR-mod.
Nivådiagnos med sensorfusion : Utveckling av koncept för nivåmätning i lutande tankar
Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.
PSQS ? Power Supply Quality Simulator
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.
Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.
Virtuell hållfasthetsprovning av en turistbuss
The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

Svensk undsättningsförmåga
I takt med att Försvarsmakten ökar sitt internationella engagemang ökar också riskerna för att svensk personal ska bli isolerad, tillfångatagen eller kidnappad. Syftet med den här uppsatsen är att undersöka om svensk undsättningsförmåga är tillräcklig för de insatser som Försvarsmakten genomför internationellt.Det kan konstateras att flera faktorer bidrar till ett behov av en undsättningsförmåga. Försvarsmakten har en moralisk skyldighet mot sin personal att göra allt för att se till att de kommer hem ifall något skulle hända dem. Försvarsmakten har heller inte råd att få personal kidnappad då det genom media och hemmaopinion kan ge ett högt tryck på politiker vilket i sin tur kan leda till att Försvarsmakten tvingas dra sig ur en insats. Förvarsmakten måste även kunna ansvara för sig själv och inte förlita sig på att en annan nation ska lösa problemet när situationen inte kan hanteras.
Axle Link - en kortslutningsskyddad säker DC-överföring
Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.
