CFD simulering av en fyrtakts Otto motorcykel motor

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Revisionsbyråernas syn på jävsregeln i Aktiebolagslagen

AbstractTitle: Accounting firms´ view on the (new law) in joint-stock companiesCourse: Business Administration, Financial Accounting in Corporations and Groups, Ad-vanced Course, 15 ECTSAuthors: Mikaela Uveby, Shadi Nourbehesht, Almira DizdarevicAdvisor: Kent TrosanderProblem: During the last few years, more importance and emphasis has been put on auditors and accounting in general due to a number of company and business scandals on both national and international levels. The United States as well as the EU consid-ered it a necessity to make regulations stricter when it comes to auditing and ac-counts in order to increase the public trust to accounting. At January 1st, 2007, Sweden also changed its law concerning accounting firm challenges. The new law states that as soon as someone of the auditor?s co-workers assists a client with some part of the basic bookkeeping, the main bookkeeping or the drawing-up of the an-nual account, the challenge situation becomes a fact.Purpose: The purpose of the essay is to examine and inquire into how the renewed law con-cerning accounting firm challenges, that was established and put to action at Janu-ary 1st, 2007, has affected accounting firms.Method: The writers have chosen to complete qualitative interviews in order to get a deeper insight to and an understanding of the topic.Conclusion: One year after the renewal of the law, the writers have reached the conclusion of that the new law has not had a great impact on the accounting firms.

Enbarnspolitik och saknade kvinnor : en fallstudie av rätten till liv i Indien

It is not unusual that women and children fall behind in development countries. It is not even unusual that these groups are exposed to all forms of discrimination due to the countries lack of capacity to erase poverty. We also know that women and children in a larger extent suffers from the shortage of proper health conditions. India is one of these countries. It is a country where women even before birth are exposed to discriminatory family planning.

Incitament för att bygga arenor när kalkyler bedöms olika : En studie om två arenor

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

Egenvård i palliativ vård : att leva eller att inte leva

Background: Within palliative care setting persons with terminal illness is cared for. The aim of the care is to enhance the quality of life for the patient through a holistic approach. The disease can lead to major suffering and require the person to handle the situation. If the person´s ability and capacity to do so is insufficient the identity may be perceived as threatened and quality of life diminished. Self-care can help a person to cope with loss of identity, enhance independence and improve quality of life.Aim: The aim of this study is to explore self-care strategies of patients within palliative care setting.

Specialistssjuksköterskans erfarenheter av att främja hälsa för patienter med hjärtsvikt : En intervjustudie på vårdcentraler

Background:Chronic heart failure (CHF) is a complex clinical condition. The higher survival rate after heart attack and other heart diseases, plus aging population, has led to more CHF patients. Symptoms can have negative impact on exercise capacity, ability to perform activities of daily living and quality of life. Heart failure clinics have been established to help better quality of life. Helping to stabilize and maintain patients´ health can reduce the need of hospital admission.

Phycoremediation of pesticides using microalgae

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

Etnicitet och demokratisering i dagens Rwanda : En kvalitativ studie om etnicitet och demokratisering i Rwanda

The purpose of this study is to explain if the existence of ethnic groups in Rwanda has complicated its democratization and explain what opportunities Rwanda has to be democratized. To fulfill the purpose of the study, I intend to answer two questions: 1) Does the existence of ethnic groups obstructed democratization in Rwanda? and 2) What opportunities has Rwanda to be democratized? To answer the first research question Dahl's theory of subcultures and democratization is used and to answer the second research question van de Walle's theory of democratization is used in the region of sub-Saharan Africa. Literature used in the study are Dahl's Polyarchy and van de Walle Africa?s range of regimes and Freedom House annual reports.

Hälsoeffekter av patientundervisning och läkemedelsanvändning vid Parkinsons sjukdom

AbstractBackgroundParkinson?s disease is a chronically not curable progressive disease that leads to different degrees of disability. Controlled studies on how patient education influences subjective health in Parkinson?s disease are lacking.AimThe aim of this study was to examine the influence patient education had on drug requirements and on subjective health status of persons with Parkinson?s disease.MethodologyA short form of Health Survey, SF-12, was used to measure perceived health. SF-12 was administered before and one month after patient education (intervention group; n= 48), and in waiting list control (n= 48).

Operationsklinikers riktlinjer och arbete med oavsiktlig anestesiinducerad hypotermi.

Background: Students, at a secondary upper school, attending a practical programme have a lower physical capacity than students from theoretical programs. Our physical self-esteem has a great significance for our motivation in being physically active and thereby also for our health. The purpose: of this study is to find out if there is a difference between perceived physical self-esteem and objectively measured physical activity between students attending a practical programme and a theoretical programme. Method: Four classes, in a medium-sized town in the southeast of Sweden, participated in the study, two classes from practical programmes and two classes from theoretical programmes. All the students were in their final year at the upper secondary school, when they were part of the study during the autumn of 2011.

Krisberedskap i grundskolan : perspektiv på krishantering

A crisis is something that can happen to all of us in an unexpected situation, and the school should be prepared in a way that is the best way to handle a situation with a wide foundation through a crisis plan. On a well-defined way, you should have a developed and relevant emergency plan. Defining the word crisis can be difficult, it is an individual interpretation, and to get found out what the word stands for and it have to be discussed. The two selected schools that I have chosen to interview have discussed the understanding of the word crisis in able to get what the word means for them. The two selected schools have come to the conclusion that a crisis is something that creates disturbances for people or a person concerned to the everyday way of living.

Transformatordiagnostik genom dissolverad gasanalys

The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.
