There are several methods avaliable to find areas of interest, but most fail at detecting such areas in cluttered scenes. In this paper two methods will be presented and tested in a qualitative perspective. The first is the darg operator, which is used to detect three dimensional convex or concave objects by calculating the derivative of the argument of the gradient in one direction of four rotated versions. The four versions are thereafter added together in their original orientation. A multi scale version is recommended to avoid the problem that the standard deviation of the Gaussians, combined with the derivatives, controls the scale of the object, which is detected.

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

The purpose of this thesis is to analyze the perception of Christianity in nine textbooks andidentify changes in-between them and over time. The content of the textbooks will also bediscussed in relation to the steering documents connected to each book.I have chosen to focus on three curriculums, Lgy 70, Lpf 94 and Gy 11. My researchquestions are: how Christianity is treated in textbooks in religious studies in relation to theperception of Jesus, God and man? What are the differences/similarities across time andlearning materials? In what way does the textbooks change with the syllabuses?Text consumption and discursive practices is analyzed with the help of a set of tools thatare based on the critical discourse analysis and Fairclough's three-dimensional model. Theimage of Jesus, if described by a textbook, is also analysed.Three textbooks were chosen from each curricula.

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

Studies of the information needs of library patrons are necessary in order for the library to serve the community. Alas, studies of non-heterosexual persons are rare in the field of Library and Information Science in Sweden. This study aims at examining the information situation of women in same-sexed parenthood by means of analysing their situation as norm-breaking. The study is done through examining the specific information needs of this group, how they seek and receive information, what barriers they encounter and what function the library has in this information situation. A queer theoretical approach to heteronormativity in combination with McKenzie?s two-dimensional model of information seeking is used to perform a qualitative analysis of the material.

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.

How does IT-consultants reason in their consulting process regarding the development of a clients IT-based internal recruitment system? The purpose with this paper is to investigate how an IT-consultant is reasoning in a consulting process and investigate whether consultants are using established models and methods in their work. We have chosen to work with a qualitative examination to attain our purpose. In our work gathering the empirical facts we have been working with a case study, an observation and a simulation exercise. The combination of these has made it possible to carry out the paper and produce the most correct data possible. Conclusion: We state that IT-consultants do not use any theory-based methods, they use process methods created by themselves and their company.

Syftet med arbetet är att simulera tävlingar på medeldistans mellan löpare med en strategi att vinna och undvika muskeltrötthet. Löparna ses som agenter vars strategi realiseras med ett artificiellt neuronnät (ANN) som med sensorer, avstånd till mål och agentens trötthet beräknar bidragande kraft och styrriktning. Agentens ANN tränas med en belöningsbaserad inlärning baserad på genetiska algoritmer och trötthetsalgoritmen är en uppskattning av hur mjölksyra påverkar muskeltrötthet.Resultaten visar att av alla agenter som utvecklats för tävling mot klockan i s.k. time trial har alla haft samma strategi och hittat samma ideala kraft för att minimera tiden. Utvecklingen av agenter för simulation av flera agenter samtidigt har varit mer komplicerad eftersom agenterna påverkar varandra och agenternas strategi har varit olika.

Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the machines and replace it with electrical motors and pneumatics. This was not done on the folding machine which is still driven by mainly hydraulics.

Förståelsen för andra människor som krävs för lyckade interaktioner, förklaras i attributionsteorierna "Theory of Mind" och "Simulation Theory. Ett vanligt men ouppklarat fenomen är det fundamentala attributionsfelet, där beteende felaktigt attribueras till inre generella egenskaper. Fenomenet reflekterar en abstrakt mental konstruktion i enlighet med Construal Level Theorys antagande om hur psykologisk distans inverkar på perception. I en modifierad Attitude Attribution Paradigm modell undersöks om spatial distans påverkar det fundamentala attributionsfelet och om skillnader föreligger mellan kvinnor och män. Kort/lång spatial distans primades genom en kontroversiell text, via information om dess kompositionsplats, som fungerade som underlag för bedömning av skribentens åsikt.

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

This thesis treats the subject of a complete steady state and dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO.

The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.

This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.
