Denna studie undersöker om det är möjligt att införa nåbarhetstestning i en baneditor. Testets syfte är att ersätta manuell testing, det vill säga att bankonstruktören inte ska behöva spela igenom banan för att säkerställa att denne kommer kunna nå alla nåbara positioner.För att kunna utföra studien skapas en enkel baneditor som testplattform. Vidare utförs en jämförande studie av flera alternativa algoritmer för att fastställa vilken som är mest passande för nåbarhetstestning i en baneditor.Resultatet från den jämförande studien visade att A* (A star) var den mest passande algoritmen för funktionen. Huruvida automatisk testning kan ersätta manuell testning är diskutabelt, men resultatet pekar på en ökad effektivitet i tid när det kommer till banbygge..

As stocks have become a more common way for people to save their money, the range of financial information has had a substantial increase. To understand the assumptions that stock valuation and analysis are built upon, it is important for the reader to have an understanding for the models that are used by banks and institutions when recommendations are published.The cash flow model, which is the most commonly used stock valuation tool, is based on CAPM. This model describes the relationship between an assets return and its risk in relation to an index. The risk parameter is called the beta value and has grown to be the dominating risk factor within financial economics literature.The use of beta values has been widely discussed in the world of academics and some researchers claim that the degree of explanation brought about by the beta is so low that it should be discarded, others are faithful to the beta and believe that it still serves a purpose. As a result of this criticism other ways to calculate the beta have surfaced, models that take other factors of risk into consideration.

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

SAAB Automobile ABis a car manufacturer within General Motors corporate group. SAABAutomobile ABhas a big part of the responsibility for the brake development in the corporategroup. The car industry is facing harder environmental requirements, which influence the brakedevelopment. The focus is to develop brakes with low drag and sustained brake feeling andperformance. Important characters for the brake caliper are high stiffness and low weight, highstiffness results in high performance and low weight is important because it is unsprung mass.This thesis investigates the possibility to improve the performance of the brake caliper for aGMproject.

As the cities are becoming more crowded, the urban distribution has become a major logistical challenge. Some commonproblems in the inner cities arelimited accessibility and idling. Many of Sweden's municipalities are above the limit values for PM10limit set by the EU.Sundsvall is one of these municipalities and has the vision to create a sustainable city and region. Sundsvall LogistikparkAB is part of an EU project, SMARTSET, which is collaborationbetween several cities in Europe. SMARTSETSundsvall is about to develop a market-based sustainable model for city logistics.

The Swedish processor Findus contracts approximately 500 pea producers annually to secure the company?s supply of green peas for human consumption. A production contract, which has had roughly the same design for decades, regulates the relation between Findus and the pea producers. Agriculture is typically a risky business. The main sources of risk in agricultural production are production risk and price risk.

Nyligen kom ett pressmeddelande fr?n Statiska Centralbyr?n (SCB) att Sverige har den l?gs ta siffran p? antal barn per kvinna i modern tid, 1.43. D?rf?r ?r det relevant att spekulera kring hur Sveriges framtida befolkningsm?ngd kan se ut, b?de p? kort och l?ng sikt. I detta arbete har begrepp unders?kts som populationsstorlek, fruktsamhetstal, f?rs?rjningskvot och befolkningspyramid, och hur dessa ter sig ?ver tid. Fyra scenarier analyserades: of?r?ndrad fruktsamhet, fortsatt nedg?ng, ?verg?ng till ?kning samt en cyklisk utveckling med b?de minskningar och ?kningar.

Aims: Patient associations have been around for some time and research has shown that such associations can influence society, politics and how diagnoses are thought of. This study is a comparative analysis of two patient associations in Sweden. The first association called Attention represents people diagnosed with neuropsychiatric disorders such as ADHD. The other association called RSMH represents people diagnosed with mental illness such as depression. The aim of this study is to explore the social and political agenda of these associations and to explain their relation to biological, psychological and social models of explanation.Method and theory: The method used was a qualitative document analysis using documents produced by the associations themselves as well as documents from media and politics.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Shaping visual stories - content in exhibitions is an essay on how content has been shaped in the two exhibitions "Memento mori" and "Hästen - tyglad, piskad, älskad". The study focuses on how exhibitions can be defined through their content as well as how the exhibitors'different intentions towards the exhibition affect the working process as well as the result. This is put in relation to theoretical models and discussions on ideals in the field of exhibition and what impels these to find an answer to the question: What makes an exhibition?.

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Drömmen om att resa utanför det egna landets gränser och upptäcka andra länder och kulturer blir allt vanligare och möjliggörs i och med allt billigare flygbiljetter. I och med detta har även backpackingresor tenderat att öka de senaste decennierna och har även kommit att bli något av ett socialt fenomen i Sverige. Uppsatsen berör fenomenet backpacking och vad en backpackingresa har för betydelse för identitetsskapandet hos den enskilde individen. Syftet med uppsatsen är att undersöka huruvida en backpackingresa motsvaras av en inre resa hos individen. Backpacking är sedan tidigare utforskat inom andra discipliner och uppsatsen önskar bidra till forskningsområdet med ett socialpsykologiskt perspektiv.

Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.
