This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Objectives: The purpose of the study was to examine if a pre- and post-operative difference could be seen in self-reported pain disability and self-efficacy among patients undergoing surgery as treatment for spinal disc herniation in order to improve process of rehabilitation.Method: A quantitative and descriptive design was used. 10 patients awaiting surgical treatment for spinal disc herniation were included at Akademiska sjukhuset (The Academic Hospital) in Uppsala. Participation was voluntary and the selection was made by convenience. Data was collected using The Pain Disability Index and Self-Efficacy Scale by which the patient would estimate how hindered they felt because of their pain in everyday activities and their self-efficacy to perform everyday activities. This was done the day before surgery and two weeks after surgery.

The study aims to describe, compare, and analyze how managers and basic staff in disability care reflects on education and competence in the organization and from an organizational context explain how the professionalization efforts can be understood at different levels of disability care. Highlighting these questions can stimulate discussion within this field when it comes to the evaluation of competence and skills of staff working with people with various disabilities, which is also sought after in society even more today. The study is qualitative and the result is based on five semi-structured interviews with managers and basic staff in disability care. The interview questions were categorized according to the concepts that are central in this essay: competence, training, professionalism and organization.The results show that there is some doubt about what a higher competence of personnel in direct contact with the users would mean. Among the basic staff uncertainty seems to be highest.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.

The Motor Group of the European Council was commissioned in the autumn of 1997 to prepare a proposal for a new European Bus and Coach Directive. In the beginning, most of the Member States did not have the accessibility requirements as their main concern; still a smaller network with actors from the National delegations from Britain, Germany and Sweden would influence the other National delegations in the Council group to finally agree to retain the requirement of accessibility of the Directive. Within the EU decision process, the European Disability movement acted as a strong player during the whole negotiation process using the proposal to a new Bus and Coach Directive as a tool to influence key actors to go towards a Directive with a strong approach for accessibility.Policy Transfer and Policy Transfer Network are used as analytical tools to understand and structure the transfer of the question of accessibility during the negotiation process. Actors understanding how the bureaucratic process works within the EU decision system have a chance to contributing for the changes in the directions they wishes for within a range of policy areas. The principal aim of the Directive was to guarantee the safety of passengers and to provide technical prescription in particular to wheelchair users.

Good comfort for the driver of a construction machine is crucial. Gearshift comfort is an important part of the total comfort. Volvo Construction Equipment Components has a simulation environment of the powertrain, SimPow, which is implemented in Matlab/Simulink. SimPow is mostly used for simulation of control strategies and performance. In order to be able to study gearshifting comfort, Volvo has an interest in developing new models for SimPow.

AbstractThe ability to read and write is a very important skill in today?s information based society. Most of us learn how to read and write, but not everyone is blessed to do this without struggle. Dyslexia is a very common learning disability and therefore I found it interesting to study how teachers teach students with dyslexia.By studying the literature and by interviewing teachers, I found that dyslexia is a very complex disability. The teachers have to adapt their way of teaching in a way that a student with dyslexia can participate.

In 2010 there will be a political resolution to ensure that the Swedish society is accessible to all citizens including people with disabilities. For this purpose a national action plan for disability policy "From patient to citizen" (Govt. Bill 1999/2000:79) has been set out with the aim of ensuring that the disability perspective will permeate every sector of society and that the approach and response to people with disabilities will be improved. The Swedish National Council for Cultural Affairs is responsible for implementing the disability policy in the cultural sector.Since public libraries in Sweden are a part of the public cultural sector, they will also be affected by the political resolution regarding accessibility. The concept underpinning library services for disabled people must be that of equality of access.

Being able to take a decision on an area you've never seen is a difficult task. It is also complicated to introduce an environment in the best way to benefit its purpose. This study focuses on the differences people notice between 2D and 3D models. To make it more concrete, the study has been linked to a case study called Ha?lsans va?g 255.

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

Being a trustee within the disability care will, in most cases, put big responsibility on the trustee both as a representative for the klient but also as a representative for the standards of the society. The assignment as a trustee is to strengthen the client and ease his/her way of living in the society. The Swedish legislation that controls the process and the regulation of the trustees, is by the authors of this paper preceived as kind of vauge, leaving a lot of room for interpretation. So  how do trustees comprehend their assignment and how do they actually interpret it? Using material from eight interviews with trustees within the disability care, this paper aims to examine these questions, and focuses only on the trustees and their experiences.

Treatment is both about the actual encounter and how individuals interact as well as the behaviour among the counterparts. Previous research shows that a person?s experience of how he/she is being treated is formed by conditions created by external factors, in literature known as the general view on treatment. The purpose of the study is to show how people with a physical disability experience the treatment from their Social Security Agency administrators. We have compared the empirical material with theories on treatment and power and analysed how this affect the interaction between the administrator and the disabled person.

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.
