The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

The Swedish commercial real estate market is in the current situation globally affected and is actively interacting with the rental and capital markets through international tenants and investors who are setting new demands on the property owners. The European Union has set new requirements as well in purpose of reducing humanity?s negative effect on the climate and therefore the international real estate market has introduced Green Building-certificates in order to decrease the real estate industry?s environmental impact.Certificated buildings with low energy consumption are a more common sight in Sweden these days. The development, however, could go even faster if there was not certain difficulties between property owners and tenants. Previous research has revealed that tenants do not always have knowledge about, or may have access to the economic benefits that a green building can provide.

This essay examines the expected impact of the statury audit exemption in Sweden from anauditor perspective and any conscious changes made on the accounting firms to meet the abolition.The theoretical framework is divided into three parts where the first deals with the concept of audit, who the stakeholders are to revised information, the auditor's function from an agent and positive accountingtheoretical perspective and the expectation gap of what an auditor cando and what the client expect audit to be. The second part deals with the audit exemptions and effects in Denmark and England. The last section addresses the current debate, studies and statements by FAR SRS, small businesses, banks and the tax authority.The essay is essentially inductive with a phenomenological operator perspective. The thesis has a qualitative approach with four respondents who are authorized or approved as an auditor with extensive experience, active on four different accounting firms. The questionnaire is divided into two parts where the first part consists of a number of very open questions and the other part of more structured questions in order to obtain comprehensive answers.The survey shows that a number of new services, certifications and authentication degrees are to be expected in Sweden aswell.

Gender is one of several factors that affect our society. According to the National Agency of Education and the values of Lpf 94, the school should communicate and counteract gender stereotypes. However, there is no demand for gender knowledge in the syllabus for Civics in upper secondary school.The purpose of this study is to investigate how two teachers work with gender in Civics education, with main focus on working practices. In addition, I wanted to investigate which conceptions students in upper secondary school have about gender in education. The method used is interviews.

The Swedish Animal Welfare Act say that all milking cows must have access to pasture in summer time. That was a gift to Astrid Lindgren o her 80th birthday from the Swedish Government. Sweden is a predecessor in animal welfare, but how well do we live up to these big expectations? In this thesis I will examine how well the pasture for milking cows works. I have been interviewing farmers with milking cows and people in the business. I have also been searching information on Internet, and using the library of Alnarp. Cows that are kept on pasture are exposed to different kind of parasites, but on the other hand they run a smaller risk to getting acetonemi, pareses and udder infection. Veterinary Pierre Nordmark means that cows on pasture are more healthy then cows kept inside all summer.

Syftet med uppsatsen är att undersöka vilken betydelse och påverkan samtalet med studie- och yrkesvägledaren har för utlandsfödda elever med icke svenska föräldrar som är sent anlända till Sverige. En kvalitativ forskningsmetod har används. Fakta har inhämtats via elevintervjuer bestående av åtta informanter från en mindre kommun. Urvalet utgjordes av grundskoleelever i årskurs nio som gjort sitt gymnasieval samt gymnasieelever från årskurs ett och årskurs tre. Resultat och analys indikerar att eleverna tycker att samtalet är betydelsefullt, eleverna får svar på frågor, får faktainformation och detta leder till ett bättre beslutsunderlag i valsituationer.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

During the last few years the harwarder has developed from a prototype into a market product. Holmen Skog owns two harwarders and uses two more owned by entrepreneurs. In previous studies it has been shown that the harwarder was a slow and expensive forwarder. In this study the unloading at road-site was studied. The goal was to describe the differences in time consumption between unloading two-sided or single-sided (only from side of the road) and also the difference between unloading with three and four assortments in the carrier.

The fast developments in information and data technology during the recent years have accentuated the need for the business manager to interpret and act on information from the surrounding environment. Today we know little about what information is really used in the unique decision-making. Further, little is known about how information should be designed to fit people with a more intuitive approach to interpreting information. This study is therefore about the difference between peoples approach to interpreting information and how information should be designed to fit those with a more intuitive approach to interpreting information. The application is made to dairy farms in Sweden. The literature review describes the strategic leadership, the decision-making process and the intuitive and the analytic thinking.

The Societety Park (Societetsparken) of Varberg here in Sweden, established in the year 1883 (1856), is one of the most famous parks in Varberg. Today it is, more or less, only used as a park that you will walk through in the wintertime, under the summer season though, the park starts blooming and then it is used for public music and singalong evenings. Earlier it was an old health resort park with its fine old traditions.The Societetsparken was a private owned park until 1902 when the town purchased it. On this plot there was already a smaller park and it was established as early as in 1856. It was called Badhusparken (The Public Bath Park) and it belonged to the hot- and cold-bathhouses, and these baths were very well frequented.

Today more and more municipalities interact across a wide range of sectors. The reasons tostart interacting are varying and for those who succeed with this form of work, there arebenefits in terms of efficiency and knowledge exchanges. But are the reasons that interactalways obvious? Sweden currently has 290 municipalities of varying size and allmunicipalities have basically the same mission, to deliver services to its residents.Information technology allows municipalities to digitize much of the workload, but theintroduction of the technique is not without problems. For small municipalities, there are greatdemands to deliver reliability and support for their internal and external services.

Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.

Bakgrund och problem: Revisionsplikten avskaffades 1 november 2010 vilket betyder att mindre aktiebolag som uppfyller vissa kriterier inte längre behöver anställa en revisor. Enligt uppgifter från Bolagsverket är det en stor majoritet av de äldre aktiebolagen som väljer att behålla sin revisor medan det hos de nyregistrerade aktiebolagen är vanligare att inte ha en revisor.Syfte: Syftet med uppsatsen är att undersöka vilka faktorer som är avgörande för mindre aktiebolag i valet att ha en revisor. Vi ska även undersöka vilka fördelar och nackdelar de mindre aktiebolagen ser med revision och om synen varierar beroende på om det är ett bolag som registrerades innan eller efter avskaffandet av revisionsplikten.Metod: I studien används en kvalitativ metod i form av intervjuer. Personliga intervjuer genomfördes med sju olika mindre aktiebolag.Resultat och slutsats: Samtliga bolag är allmänt positiva till avskaffandet av revisionsplikten och menar att majoriteten av mindre aktiebolag inte har ett behov av en revisor. Majoriteten av bolagen anser att revision är en bra kvalitetsgaranti gentemot ett bolags intressenter.
