Detektering av in- och utandning vil bilkörning med hjälp av Matlab
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.
Jönsaplan blir Östra torget : ett torg för sin tid
This project is about Jönsaplan in Landskrona. Jönsaplan is situated at the center of Landskrona in a part called Södra centrum which the municipality is developing, mainly by building new residential buildings. Today, Jönsaplan is not a functioning square. This is due to a ferry terminal and its many fences that block the way for people. In this project, I have assumed that the ferry terminal will be moved somewhere else so that Jönsaplan can be a real square.
By studying The Concise Townscape by Gordon Cullen and Byens uttrykksformer by Thomas Thiis - Evensen and three reference places, Daniaparken, Raoul Wallenbergs torg and Norr Mälarstrand, I came up with a number of guidelines for my design proposal for Jönsaplan.
Relationship between moose (Alces alces) home range size and crossing wildlife fences
Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.
Carbon Critical Masterplanning tool : klimatpåverkan från samhällsplaneringsprojekt
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects.

The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case.
A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety
of combinations for energy supply to the future area. The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle
perspective is applied.
Analys av QoS i mellanvaran Meteor
This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.
?Man känner sig en aning bekymrad? : En statsvetenskaplig studie av hur svensk media problematiserar övervakning
This thesis examines how Swedish newspaper media problematize surveillance. This is done by analysing the media reports from two major surveillance events: the debate in 2008 about the legislation concerning the expansion of the rights of Försvarets Radioanstalt to monitor internet and telephone traffic crossing the Swedish borders, and the revealing of an ethnically based index including over 4000 individuals created by the Swedish police. The thesis sets out to expand the knowledge about media?s role as a interpreting source of information concerning how people understand and relate to surveillance (Barnard-Wills, 2011; Carlsson, 2009; Greenberg & Hier, 2009). The thesis attempts to answer the question whether Swedish media problematizations regarding the abovementioned surveillance events correlates with the most common theories of surveillance critique.

Daily rests of wild boar Sus scrofa sows in southern Sweden
For a few decades, the wild boars are established over large areas in southern and centralSweden. Where they cause problems in terms of damage to crops in the agriculturelandscape, where rooting, browsing and trampling, but also damage to the crop when wildboars chosen daily rest in the cultivated fields. Along with the growing number of wildboars the rate of car accident with wild boars has also increased.Here I examined the daily rests of wild boar (Sus scrofa) sows in southern Sweden, todetermine the factors which the wild boars sows choose for daily rest. By determining whatfactors are important in this selection of daily rests, we may be able to make managementmeasures to reduce the damage wild boars make in the agriculture landscape by attractingthem to places where they do less economic damage and accidents on roads.In this study I have examined 123 daily rest positions from 14 different individual wildboar sows fitted with GPS collared in Southern Sweden, Skåne County in Christinehof,Högestad Kronovalls estate. Data was collared over the years 2004-2006 during the periodfrom June 1 to September 30.
Beaktande av hälsorisker från luftföroreningar vid lokalisering av nya bostäder i Stockholm : En fallstudie av fem projekt intill Essingeleden
Andelen människor som flyttar till städer ökar, vilket gör att det blir allt mer konkurrens om markytan. För att skapa fler bostäder tas mark i anspråk som tidigare haft andra syften eller bestått av naturliga grönytor. När växtlighet prioriteras bort minskar ekosystemtjänster som har förmåga att rena stadsluften. Denna studie baseras på Stockholm, där den regionala översiktsplaneringen åsyftar att staden ska förtätas för att skapa mer centrala bostäder. Att stadsluften är förorenad är ett generellt problem som utsätter invånare för hälsorisker. Detta är en fallstudie som granskar hur luftföroreningar uppmärksammas när nya bostadsprojekt är planerade att etableras.
Metodik för detektering av vägåtgärder via tillståndsdata
The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.
Stadsrum för barn : en skolgård som mötesplats
In my opinion, the city is a place fit as much for children as for grown-ups. I
have noticed, however, that this is not a view shared by everyone.
Does not the urban space belong as much to children as to other people?
Yes, of course. Today and in the future most people will live and grow to be
adults in cities. I would even take it as far as to say that without children,
there will be no real city.

This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.
Trädgårdsergonomi : om konsten att undvika de vanligaste riskfaktorerna för hälsan i små trädgårdsföretag med krukodling
This paper is based on a literature review and interviews made with managers in small-scale nurseries for pot plant production. The review helped to identify the worst occupational hazards in pot plant production. The interviews provided a way to investigate how the nurseries act so as to avoid the worst hazards and what they do to even out work intensive periods during the season in order to get a more even distribution of work over the year.
According to available statistics problems with back and shoulders are the most common of the physical disorders and the risk for occupational accidents are high for greenhouse workers. Most of the occupational injuries are connected to musculoskeletal problems. The handling of material is often manual and involves frequent lifting and carrying of heavy loads, the strenuous work postures and static muscular tensions these repetitive tasks are associated with causes straining and overloading.
Värdet av tystnad : en värderingsstudie över Upplands Väsbybornas betalningsvilja för reducerat flygbuller
Since the spring 2003 the tenant-owner home association the Terrace in Upplands Väsby municipality lies straight under the approach route to Arlanda Airport?s new third landing chute. Noise levels of over 70 dB have been measured in the area, which exceeds National Board of Housing?s, values for traffic noise at a terrace in connection to housing.
By using the method of hedonisk pricing the essay tries to find out if there exists a willingness to pay to reduce the noise in the area.
