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.

This paper is an event study on Initial Public Offering?s return behavior after the dot com bubble. Cumulative Abnormal Returns are used to measure the performance against a market index. The results suggest that the market correctly prices IPOs in the long run thus upholding the Market Efficiency hypothesis. Moreover, value weighted CARs show that large IPOs are more likely to outperform smaller IPOs, however in the long run there is an unpredictable pattern.

In conjunction with today?s increasing competition within the construction sector, more pressure is being placed on building contractors. Efficiency and improvements are necessary but without impairment to an ergonomic and safe construction site. This in is in order to reduce the construction costs and time but to retain the ability to deliver a high-quality contract.Various methods and prefabrication degrees are used, depending on the project's requirements and conditions. This analysis sets out to investigate and exhibit what qualifications are important when choosing a construction method for curtain walls.Advantages and disadvantages with each method have been analyzed and recommendations have been given to show when different methods are best suited.

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

This essay will explain the effects of decentralisation, and what impact it has on the efficiency to create a better integration for immigrants on the Swedish labour market. Examples of literature that has been examined are Marcus Gossas and Jon Pierre. From these authors, I have been trying to explain the relationship between decentralisation, cooperation and efficiency.Since the end of the Second World War until the middle of 1980, Sweden mostly received labour immigrant. Since then, the immigrant pattern has changed to consist of mostly refugees. Changed immigration patterns together with increasing debts for the Swedish government has lead to decentralisation and cooperation between public authorities has therefore become a target to reach better efficiency.

The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

Due to fast growing and rapid changes in markets today, most of the organizationsthat are trying keep up with these changes have a high demand for software that areof high quality and comes with a low price. To meet these goals software companieshave to implement new methods to develop software that are suited for rapidchanges. The concept of agile methods can fulfill this need. Our purpose with thisthesis was to investigate how well agile methods could be applied in organizationsthat could be identified as adhocracies. A case study was conducted in anorganization which we could identify as an adhocracy.

In todays society IT in general and the Internet in particular are given elements in people´s everyday lives, and smartphones has come to be a big part of those elements. This study focuses on how the use of Smartphones in particular influences the individuals in their working environment, and how this use influence the efficiency and the well-being of said individuals.  To answer our research question regarding how said use comes to effect the efficiency and the well-being for proffesionals in their working environment we have used data from qualitative interviews who is enriched by a short initial diary study. This data has then been analyzed using the Affinity Diagrams Technique, leading to four central themes emerging from the data. The results show that smartphone use at work comes with both positive and negative effects; efficiency increased through the use of smartphones due to the great versatility that comes with the technology, while in terms of well-being issues of stress emerged.

The project has been oriented for development of fixtures to ateljé Lyktan to provide a more efficiency line. In the year 2012 the company invested in a new coating booth, which leads to opportunities to upgrading the fixtures and also new design. The request is to minimize the area for storage of fixtures, and therefore should fixtures be designed to apply as many articles as possible The priority of products that fixtures have development to has been products that are most frequently coated and new products that don?t have any fixtures. The product families that the project has been having focus on is TIME and FOVEA with RONDO.

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

The society of today can?t manage without transportation. We need transports to getfood, to go to work and to create new products. The transportation ofgood is thus an important part in the function of the society and they?ll increase, bothin number and in amount.

Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.

Over the next few years, major investments in healthcare buildings is to be performed. Most surgical theaters are in need of technological upgrades as the technology is outdated. In most cases not only a refurbishment is performed but also an expansion. The basis for expansion, is due to a large increased number of patients, but also to the complexity of the refitment. Partly it's because evacuations are difficult to implement and the disturbance that occurs in conjunction with the refitment.Löwenströmska hospital undergoing a technical upgrad.

AbstractAbout 160 000 persons living inSwedensuffer from some form of dementia. Alzheimer disease is the most common form of dementia and affects mostly people in the age of 65 and older. People with some form of dementia have memory problems and may even have other problems as aphasia and behavioral disorders. This may lead to communication problems and difficulties for the people around them. The number of demented people is increasing; it is therefore important to study methods for communication in order to improve the wellbeing for people with dementia.
