Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

In this essay I have examined text, speech and action in Chekhov's Three sisters, as well as how the characters express their wills in action and in speech. I have used different methods such as action analysis, the five W questions and BSI (background, situation and intention). These methods are similar to those actors use to uncover situatedness of characters and to find motivated and intentional patterns behind their actions.I have used these techniques to identify the plot, explore what happened before the plot begins and to read the text in terms of action. The aim was also to find the counter points where wills expressed in action are contradicted by wills expressed in speech. Using these methods I found that the characters in Three sisters manage their lives dreaming about the future or recalling the past, except the character Natasha.

Background: The regulation of banks is increasing in order to stabilize the financial market. Despite this increase in regulation, financial crises still continue to occur. The Basel Committee on Banking Supervision is gradually increasing the capital requirements for banks, yet the increase in capital requirements doesn?t seem to solve the problem. This raises the question: how does capital regulation affect banks? Purpose: The purpose of this study is, primarily to illustrate the effects that capital regulation has on risk and efficiency on banks within the European Union, but secondary also study the relationship between risk, efficiency and capital regulation.Method: To achieve the purpose of this study, a deductive approach has been used, where the problem is assumed to be due to an agency problem.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

This thesis suggest an explanation for is how it is possible to understand that the large arena project in Växjö grew to cost sums of money that initially in the project not would have been an alternative to discuss, how goals changed and how the institutional environment changed the prerequisites of the project. As empirical part of the research, to describe and analyze the project, the municipality?s documentation of the project have been analyzed and semi-structured interviews have been made. Theoretical perspective is taken from the neo-institutionalism in sociology of organizations and change, and theories of the complexity of large projects with major symbolic value and importance. The project starts with the municipality?s investment and cost to be hold back, defined as a necessary condition in order to fulfil an ambitious drive towards new sport arenas.  Eventually the necessary condition was abandoned and the arenas were built with the municipality responsible for the investment, cost and risk in the project.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.

The natural sciences and the humanities are associated with differentpublishing patterns. Open Access publishing are mainly associated withthe publishing patterns of the natural sciences. Many Swedishuniversities and research funders are proponents of Open Accesspublishing, what will that trend mean to the scholars with a publishingpattern not corresponding to Open Access? In this paper literary scholarsare interviewed for the purpose of learning the motives and strategieswhich form their publishing pattern, and how they relate to Open Accesspublishing. The results show that literary scholars are less competitiveand hold a more gentle knowledge-sharing ideal, than natural scientists.The drive to gain acknowledgment and the recognition of colleagues inorder to collect academic capital as Bourdieu describes the academicfield is still present though.

The background of this study is the fact that it nowadays is more common to grow wheat after wheat. Usually we plow every autumn to remove the straw, and we wanted to study the effect of alternative methods to do it. We have done this experiment to answer the question if no tillage is better than conventional plowing. The results of the field experiment indicate that there is a link between plant establishment and the choice of equipment, but also a higher weed pressure in experimental plots with only ground tillage. The equipments which left much straw on the top of the ground the problems with fungi were more severe.

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.

Den här uppsatsen grundar sig i en enkätstudie riktad mot publiken av realityprogrammet Paradise Hotel som sänts på TV3 hösten 2014. Anledningen till denna studie var att se hur publiken mottar programmet, vilket motiv dem har och vilket behov som uppfylls med sitt tittande. Och även där jämföra mellan män och kvinnor och hur ofta dem tittar. Detta för att se varför ett så omtalat program som Paradise Hotel toppat listorna över antal tittare hösten 2014.Teorierna som använts i denna studie är Uses och gratifications-teorin och den danska mediaforskaren Kim Schrøders multidimensionella teori om mottagande. Det främsta materialet samlades in med hjälp av en enkät skapad i Google Docs och som delades via Paradise Hotels officiella facebooksida.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.
