The aim of this report is to increase the knowledge about the use of infrared cameras within fire services. A construction made up of several different types of walls and ceilings was built and used in a large scale fire test. The actual temperature was measured with thermocouples and compared to the temperature given by infrared cameras. The heat wave and the infrared images themselves were also
The accurate and reliable detection of opening of doors and windows is vital for home security applications. This master thesis aims to present a way to achieve this using a low-cost and low-power ecompass, containing a MEMS accelerometer and a magnetometer. This has been achieved by attaching such a device to a door and collecting sensor data when opening and closing the door. Said data were then
Arbetsgivare använder sig allt mer av olika övervakningssystem av diverse anledningar. Även då det är en vanlig metod är övervakning ett negativt laddat ord och många är osäkra om den personliga integriteten bevaras. Syftet med denna studie är att undersöka vilka effekter övervakningssystem har. Jag försöker lyfta fram fördelar och eventuellt reducera en del av den negativitet ordet medför. Den em
This study aims to examine the topic of innovation in China. The need for innovative development is of importance for the nation to keep the rapid development. A few evaluations of both Chinas indigenous innovation policy and the opportunities for the citizens to develop innovation has criticized the lack of creativity in human resources and the examination based education system to be harmful for
In this thesis a system is developed for robust time difference estimation for multiple microphones in reverberant environments, without any knowledge of the 3D positions of the microphones or the room. RANSAC is used to find line segments in sets of frames containing a number of the largest GCC-PHAT peaks. Focus is on real experiments with one moving sound source continuously playing music. The e
A sustainable approach could be a solution for the tourism industry to reduce its climate impact. The aim of this thesis was to develop a sustainable tourism strategy, in collaboration with Swedish region Halland. The sustainability concept was set against the developed tourism strategy, both on a theoretical and practical level. The strategy was compared to other sustainable tourism strategies a
In this work graphene has been functionalized with antibodies. Different functionalization methods of graphene already found in literature have been evaluated. An electrochemical functionalization process with subsequent immobilization of antibodies have been chosen for this thesis. The purpose of the thesis has been formulated in collaboration with Graphensic AB. From them a wish to implement an
Studien undersöker empiriskt sambandet mellan korruption och ekonomisk tillväxt i utvecklingsländer. Utöver det direkta sambandet mellan korruption och BNP-tillväxt, studeras även indirekta samband genom estimeringar av korruptionens påverkan på etablerade kontrollvariabler för tillväxt. Kontrollvariablerna, vilka även utgör potentiella överföringskanaler för korruption, utgörs av: investeringar,
Den här uppsatsen utreder möjligheten att använda en modell som skattats med tidsserieanalys i Konjunkturinstitutets (KI) prognoser på offentlig konsumtion. Autoregressiva modeller skattas på realtidsdata från 1994. Modellerna skattas och utvärderas med out-of-sample prognoser. Modellernas prognosförmåga utvärderas mot första publiceringen av statistik för offentlig konsumtion för perioden 2004–20
In today’s competitive vehicle industry, fuel efficiency and weight plays a crucial role in performance and to maintain an attractive market position. The increasing technological development is opening new possibilities to design components with lighter materials. All components on Scania buses are favorably designed with as low weight as possible since the measured load on the back axis determin
The aim of this paper is to present the kinds of error that implicit bias can cause when we are to judge and rank which available candidate is the most suited for e. g. a job vacancy, and to investigate whether we can de-bias ranking lists in recruiting processes given that we suspect that implicit bias has influenced the ranking. I will argue that the available methods for this (positive discrimi
The North Sea stands out as one of the most rapidly warming regions of the globe and various types of geographic distribution responses have already been reported, from latitudinal changes to vertical changes. Using catch data from an international bottom trawling monitoring survey, this study investigated how the range size of the North Sea fish assemblage has changed during the last three decade
As the development of human civilizations, the classic definition of crowdedness index or population density is not able to describe population dynamic conciliations properly. Furthermore, the detailed population information is normally only stay on urban or country levels. Methods to compute crowdedness index of a small scale-area are lacked. Demographers need some new methods to compute human cr
The harbour porpoise (Phocoena phocoena) is the only cetacean regularly found in Swedish waters. Little is known about its movements and behaviour. Around the peninsula of Kullaberg, harbour porpoises are regularly found in relatively large numbers and they are considered to use the area for both feeding and reproduction. Along the northern coast of Kullaberg six passive acoustic data loggers; Cet
Syftet med denna studie är att undersöka vad som får elever att börja spela brassinstrument och vilka faktorer som motiverar dem till att fortsätta på Musik- och Kulturskolan. Bakgrunden till studien är att antalet elever på brassinstrumenten i Musik- och Kulturskolorna har minskat i Sverige under lång tid. Data består av gruppintervjuer med 11 elever i tre åldersbaserade grupper. Resultatet viThe purpose of this study is to investigate what motivates students to begin playing a brass instrument and the factors that motivate them to continue in the Community School of Music and Arts. The background for this study is that the number of students on brass instruments in the Community Schools of Music and Arts in Sweden has been decreasing for many years. Data collection was performed thro
Det proportionella valsättet bygger på tanken om en samförståndsmodell där olika intressen representeras efter sin storlek, att besluten växer fram efter förhandlingar och att man överbryggar klyftan mellan majoritet och minoritet. Det proportionella valsättet är således ett minoritetsskydd som tillförsäkrar även de mindre politiska partierna rätt till förtroendeposter och därmed makt och insyn.
Type 1 Diabetes (T1D) is an immune-mediated disease where the pancreatic beta cells are selectively destroyed by autoreactive CD8+ T cells. However, the triggering events that eventually leads to autoreactive CD8 T cells infiltrating the pancreatic islets and, subsequently, destroying them still needs to be unveiled. Genetic and epidemiological evidence points to a substantial influence of environ
Map design research has strongly come into the agenda with the extensive use of GIS and maps in geoportals. Geoportals are used to find, access and display geographic data via the Internet. Novel opportunities and techniques for displaying geographic data in viewing services also introduce new challenges and issues in cartographic design. Specifically, thematic polygon layers (foreground) will obs
The thesis deals with how to price swing options in the electricity market by using a least squares Monte Carlo method. This is a simulation method which uses a backwards moving algorithm where the optimal decision is calculated at every time step. Regression is used for the optimal decision and in this thesis both a polynomial regression and a cubic smoothing spline are used. They are both shown
I undersökningen ”Fokus på förskolläraruppdraget” har jag undersökt hur förskollärarna uppfatar sitt uppdrag samt hur de omsätter uppdraget i praktiken. Jag har även undersökt vilken påverkan kommunikationen har för förskollärare i deras uppdrag. Jag har avgränsat mig till att samtala med förskollärarna eftersom de har det yttersta pedagogiska an-svaret för verksamheten. Undersökningen är en kvali
