BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

This report is intended to give an insight in the Network Performance Assessment Modeland the parameters that is needed in the making of a fictitious grid that represents anoptimal grid. A main goal is to investigate how the construction of a real grid iscompared to the fictitious.One of the key parameters is how redundancy is treated in the model and to find theoptimal amount of redundancy versus the costs. Further is the dimensioning of the grid ofinterest. The fictitious grid is based on energy whereas the real grid often is based onsubscribed power and these two principles are compared and analyzed.The difference in the outcome of the model result due to variations in input data of themodel is also discussed in the report..

År 1996 avreglerades den Svenska elmarknaden vilket innebar att elpriset övergick från att vara reglerat till att bli konkurrensutsatt. I denna uppsats analyseras elmarknaden och dess förändring i struktur och prisbildning sedan avregleringen. Detta görs genom en Structure-Conduct-Performance analys där marknadsprestationen ses ha ett samband med marknadsstrukturen. Marknadsprestationen belyses närmare genom en analys av konsument och producentöverskottet. Våpr slutsats är att inga välfärdsvinster har uppstått till följd av avregleringen utan snarare tvärtom, och det verkar inte heller bli en mer konkurrenskraftig marknad i framtiden..

Syftet med examensarbetet är att hjälpa ett företag med att införa standardlittera för deras prefabricerade betongelement som ingår i deras Konceptet. Införandet av standardlittera ska resultera till att återfinna och gruppera deras betongelement i CAD-systemen. We did our thesis project at one of the most prestigious Swedish construction companies. We have examined the possibilities of doing sandwich elements to standard elements which would increase the degree of industrialization. The company has developed a concept that is based on a more refined process of industrialization.

In this paper, a small business network with around 30 users is analyzed with respect to security, performance and usability. Based on this analysis, two suggestions on how to solve the problems listed are given. The first suggestion focus on keeping a low budget, while the other tries to deal with the problems more thoroughly. One advantage of the first suggestion is, in addition to not straining the company's budget more than nessecary, it does not involve too great changes in the way the network is used and administered. On the other hand, the smaller budget leads to certain compromises, and there is a risk that similar problems occur again if, for example, the company would grow.

There has been an increasing interest for ranking of Swedish health care and a lot of emphasis has been placed on the creation of indicators in order to rank hospital units. However, essays on to what extent the choice of statistical method affects the final result of the ranking of health care units have not been given the same attention. For this particular reason, the main objective of this essay has been to investigate whether the choice of statistical model has a significant impact or not on the final result, by using five different, more or less common, statistical approaches: bar charts (with and without confidence intervals), control charts, logistic regression, multi-level analysis using shrunken residuals. The analyzed material in the essay comprises 24119 patients that all have been prescribed some form of the lipid-reducing medicine statin. According to directives given by Region Skåne, doctors are encouraged to prescribe a particular type of statin medicine, namely Simvastatin, which has been proved to be equally effective, but significantly cheaper than other statin medicines.

Swedish agricultural businesses are facing challenges in order to achieve long-term profitability. The opportunity to improve profitability and efficiency on farm level may be enhanced by management. One way to work with leadership is to use Lean. It is a management system that aims to improve competitiveness. Currently, there is a project where Lean is implemented into 100 agricultural firms.

The aim of this essay is to investigate the function and development of non-player characters (NPC) in the TV/computer game Dragon Age: Origins. The NPCs are analysed in order to see if their development is affected by the player character?s (PC) background and interactions. The game?s ethics is also investigated by studying how the NPCs treat the PC and what significance they give to his background and actions.The results show that the NPCs are affected by the PC?s interactions, and furthermore, that they are round characters, which is unusual in TV/computer games.

Problem statement and purpose:The purpose of this study was to analyze in what way first-time voters chose to take part of political information. The questions we aimed to answer was how first-time voters use media and other information channels for political purposes, what importance and trust the first-time voters give the different information channels and finally which indicators there is for that structural or individual factors affect the media consumption and political interest.Method and material:We did interviews with twelve 18 years old first-time voters from six different high school programs in Sundsvall, Sweden.Results:The study showed that the premier source of political information were traditional news media, in particular the debates on TV. It?s also in the debates the first-time voter?s trust the most. Even though the social medias are constantly present in their everyday life and even though the first-time voters believe the social medias have potential for engaging young people politically, the possibilities are only taken in advantage by people who are already politically interested.

The automotive industry is a highly competitive market characterised by low profit margins or huge losses. Cost reductions have been of top priority for all OEM?s (Original Equipment Manufacturer) and will continue to be so for many years to come. Beside cost reductions, reducing the time-to-market is of greatest importance to stay in the competition. OEM?s that are slow to market with products that neither matches customer expectations nor the products of their competitors, will soon loose market shares and see their economical performance falter.

This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower.

One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).

The purpose of this study is to analyze the interrogation transcripts of interviews with girls between the age of 11 and 16 who are alleged victims of sexual crimes. The examination is done from a gender perspective, by comparing six interrogations by male interrogators and eight interrogations by female interrogators. The study has used linguistic indicators relating to the interrogation methodological guidelines, in order to highlight how the interrogators give girls the opportunity and space to share their experience of the alleged sexual offense. Text material is categorized based on themes and analyzed in detail to find any gender-specific patterns of hearing leaders and if the girls are given space and opportunity for a free storytelling. The results show that in several themes, differences between the male and the female interrogators can be discerned.

Bakgrund: Under 1900-talet skedde flera teknologiska framsteg och Relevance Lost-debatten förändrade synen på den traditionella ekonomistyrningen. De två målstyrningssystemen, det balanserade styrkortet och Hoshin Kanri, anses delvis besvara kritiken samt möjliggöra för företag att implementera sina strategier. Begreppet målkongruens beskrivs på olika sätt av olika författare, varför begreppet är intressant att undersöka samt hur målkongruens kan uppnås i företags planeringsprocesser.Syfte: Syftet med denna uppsats är att beskriva planeringsprocessen i målstyrningssystem samt att förklara hur målkongruens uppnås. Vidare är syftet att precisera begreppet målkongruens samt formulera en metod för att stärka målkongruens.Metod: För att uppnå uppsatsens syfte har två fallstudier gjorts med två företag som arbetat med att implementera och utveckla arbetet med ett balanserat styrkort och Hoshin Kanri. Tre intervjuer har genomförts på respektive företag med personer med god insyn i och erfarenhet av arbetet med målstyrningssystemen det balanserade styrkortet och Hoshin Kanri.Resultat: De båda målstyrningssystemen är mycket lika.
