Mekanisk modell av människans huvud för simulering av skalltrauma och hjärnskada
In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.
Kundanpassad LCA för nätverkskameror
Antalet övervakningskameror i samhället ökar, samtidigt som deras miljöpåverkan är relativt okänd. För en produkt som tidigare bara utvärderats gällande prestanda, börjar kunderna nu efterfråga en kartläggning av miljöpåverkan. Kamerans miljöpåverkan studeras ur ett livscykelperspektiv: energi- och materialtillförsel samt utsläpp och avfall som berör allt ifrån råmaterialutvinning till slutåtervinning. Projektet är genomfört på begäran av, och för, Axis Communications AB (härmed refererade till som Axis) med huvudsyfte att öka Axis kunskap om deras produkters miljöpåverkan och utveckla en metod för genomförande av förenklade livscykelanalyser på Axis produkter. Livscykelanalysen, LCA, genomförs på en nätverkskamera utvecklad av Axis Communications AB; modell AXIS Q6032-E PTZ.
Augmented Reality i mobiltelefonen : En kunskapssammanställning med trafikinriktning
This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.
Förbättrat råvaruutnyttjande vid kvalitets-sortering av timmer : utvärdering av analysprogrammet Stockholmen för automatiserad timmersortering i dimensions- och kvalitetsklasser hos BARO WOOD AB
The aim of this thesis was to analyse BARO WOOD AB:s timber measuring and quality sorting and to evaluate the analyse program Stockholmen. The purpose was to get a better understanding for the quality sorting made at BARO WOOD AB today, analyse differences in center board quality from logs with a good quality and logs with a bad quality, suggest new sorting criterias developed from analyses made with Stockholmen and to evaluate the program Stockholmen. All analyses are based on data gathered in a test sawing made at BARO WOOD AB in June and July 2002. The test sawing was made on four different diameter classes and every diameter class consisted out of A or M-grade logs, with a better quality, and B-grade logs with a lesser quality. The logs where sorted out with BARO WOOD AB:s existing quality criterias.
Mekanisk integration av en IR-detektor i en Stirlingkylare
The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.
Lane Keeping Aid : ett förarstödjande system för bilar
Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.
Gallringsinventering från helikopter utrustad med profilerande laser och kamera för låghöjdsfotografering
Today Holmen Skog finds and selects suitable thinning stands using data on upper height and basal area. These figures are often based on basic forest data that has been updated with the help of growth prediction models. The problem is that these figures are not always correct. The aim of this study was to investigate if a combination of data from a profiling laser and a digital camera for low elevation photography, can be used for collecting data on number of stems per ha, tree species mixture as well as basal area weighted mean height and upper height for stands. The possibility to use these data to assess the need for thinning cutting was also investigated.Laser data and aerial photographs were collected from a helicopter operating at an approximate height of 100 meters.
Betongpelare och brand : En utvärdering av 500 °C isotermmetoden
At the beginning of 2011, Sweden started using the European rules for structural design, the Eurocodes, instead of the previous national rules. In both the previous rules and the Eurocodes, it is possible to dimension concrete columns using tabled values. However, the required cross section measurements have increased considerably. Moreover, it is possible to dimension concrete columns using calculations, however, this is unusual.The development of a fire in a fire cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g.

BeAKKta : ett kommunikationshjälpmedel som möter behoven av djupare kommunikation hos personer med autism
A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.
Att utforma den perfekta skandalen : En studie av hur Expressen rapporterade om SD-skandalen i november 2012
Title: How to Construct the Perfect Scandal ? a study of the news reported by Expressen concerning the SD-scandalAuthor: Linnea IvarssonThis C-paper presents the incident concerning the political party Sverigedemokraterna in Expressen in November 2012. The newspaper was the main source of the news reporting with the mobile phone camera film from the occurance and led the way of the news reporting in Sweden about three party members.The paper investigates how the story telling of the so called SD-scandal was constructed, using Critical Discourse Analysis as the analysis method combined with selected parts from the analysis method of critical linguistics. The theories that have been used to establish the results of the analysis are Critical Discourse as a theory based on Norman Fairclough and Teun A. van Dijks theoretical keystones combined with Sigurd Allerns and Ester Pollacks theories and schematic point of view on the constructions of political scandals in media.With the theories and analysis methods above mentioned the results turned out to confirm the theory about how political scandals in media are constructed and designed with certain strategies and agenda.
