Konceptstudie av drivmodul till bandskotare med hybriddrift
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.
Bibliotek och jämställdhet. Hur det kan bli en självklarhet. ? en studie av ett folkbiblioteks arbete med jämställdhet.
The aim of this bachelor?s thesis is to investigate what role the public library in Sweden may have when it comes to gender equality issues. The questions at issue that were asked, in order to give an answer to the aim, was how the librarians defined and saw work with equality, how much the steering documents for the library impact and what they are doing in their practice to weaken the dichotomies between the sexes. The theoretical starting point used for this study is three concepts, the gender system, the stereotypes and the gender contract described by the Swedish historian Yvonne Hirdman. The purpose of the three concepts is that gender is a social construction which produces gender stereotypes and a gender order in society, which the library is a part of.
Ansvarsfördelning i teori och praktik. En implementeringsstudie av mottagandet av ensamkommande flyktingbarn i Sverige
This case study explores the question of implementation and steering in a society of governance. As an empirical example, a reform concerning the reception of separated refugee children in Sweden is used. As of the 1st of July 2006 the responsibility for providing housing for separated children lies with the local governments rather than with the Swedish Board of Migration, aiming to improve the children's situation. However, implementing this amendment has turned out to be a harder task than expected. Traditionally, the relationship between state and local actors is seen in terms of state steering or local self-government.
Folkhälsopolitikens praktik - En studie av tre kommuners implementering av folkhälsopolitiken och dess syn på befintlig styrning
The purpose of this study is to analyse how the local governments have implanted the new public health policy, which Sweden adopted in April 2003. The new health policy stakes out a new direction for national public health policy. Instead of focusing on diseases the new public health policy focus in factors that determine health.Important factors to study are the role of central steering from the central government. The method used is a case study of three Swedish local governments. The main material used is interviews and different policy documents within the area of public health.The conclusion of the study shows that the local governments are fairly satisfied with the steering of public health policy by the central government.
Sverigedemokraterna - en textanalys - en granskande analys av ett partis politiska texter
The purpose of this dissertation is to examine and present six different texts produced by the Sweden democrats. This examination focuses its attention on the content and the technique of the arguments present in the texts. In addition, the results will be put in relation to the steering documents for the Swedish school system. The aim is to observe common features regarding content and technique present in the texts. More specifi-cally, I will examine how the texts produced by the Sweden democrats pose a problem to the Swedish school system.
I nationens intresse - operation:jämställdhet- genuint engagemang eller projicerad legitimitet - En fallstudie på den Svenska Försvarsmakten
The Swedish Armed Forces is a public institution and consequently obliged to follow Swedish and international legislation. Thus, they are subjected to contrarious demands from different actors operating in its high-technological and high-institutional environment: to be a legitimate institution and at the same time operate with a high level of efficiency. This thesis is conducted with the aim of investigating whether The Swedish Armed Forces' steering document for gender equality is used to achieve visible and quantifiable results or if the document constitute a medium for reverberating legitimacy. To answer the research question, we applied a critical discourse analysis on the relevant documents and on the conducted semi-constructed interviews with members from different levels and positions in the organizational hierarchy. Subsequently, we came to the conclusion that the Swedish Armed Forces manage the demands for efficiency and legitimacy, which are forced upon them from the technological and institutional environment, by talking about them.
Vision Enhancement System : Vilken betydelse har displayplaceringen?
At night, the visibility is reduced and the demands on the driver increase. A safety system that enables the driver to discover warmer objects in the surroundings when the visibility are reduced, such as the Vision Enhancement System (VES) contributes to safer night-time driving. Since the benefits of this system are established, it is of interest to investigate different design aspects. The VES display has in earlier studies been positioned in front of the driver but different display positions such as peripheral placement should be evaluated. The present simulator study is an investigation of the effects of different display positions inside the car.
Skolan som institution : En processtudie av skolpolitikens skeenden
This thesis has aimed to study steering process and institutionalization in the context of educational policy work. This has been conducted by using empirical material from the political decision-making process that preceded the implementation of a new national program on how principals should be educated and certified. By using an aggregated theoretical point of view containing new institutionalism and traditional Swedish curriculum theory, the process was analyzed from different perspectives. The results depict a process that contained several actors who tried to shape the principal education program differently. From the theoretical perspectives, the decision-making process could be understood as an act of both self-interest as well as trust in their own beliefs and cultural values.
Utvärdering och implementering av automatiska farthållare i fordonssimulator
Vehicle simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice simulator will be described and a comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.

The thesis is based on qualitative interviews. Those interviewed have participated in "Book Wheel".
Redovisningsprincipers påverkan på investeringar: En studie av ett svenskt industribolags nya styrmodell och dess implikationer
Recent studies show that manufacturing companies to a larger extent use historical cost accounting in their internal accounts, at the expense of calculated costs. The explanation behind this is claimed to be that firms are subject to careful scrutiny by the stock market. Consequently, top management stresses the need of evaluating all parts of the firm from external accounting. However, lower management levels express a general concern that the incentive to invest in machines will decrease. This master thesis aims to investigate whether or not there is an objective reason behind this concern.
Konstruktion av serviceutrustning till tunnelborrningsmaskin
The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.
Pressning och hantering av halm som energiråvara
I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.
Verksamhetsstyrning med fokus på intressenters och medarbetares betydelse : ett fundament för företagens varaktiga framgång?
We would like to gain a more in depth knowledge of whether the modern orientations both within corporate governance and control philosophy lay the foundation for enterprises? more sustainable success. These both modern orientations are increasingly focusing on the importance of enterprises? setting of goals and visions on the basis of stake holders? interests and the employees? more active engagement in and motivation for the goal achievement. Despite these common inherent characteristics, it is not evident from current scientific debate how such integration actually emerges in the control philosophies of the enterprises.
