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.

Lean Product Development is a knowledge-based business concept in order to maintain high quality, meetcustomer requirements and to make product development more efficient. An important part of the processis to add a lot of resources at an early stage and execute the development as an iterative process betweendepartments exploring many alternatives thoroughly. The work focuses on how Lean ProductDevelopment is carried out and explores how to manage interaction between different departments andexpertise with regard to cross-functional collaboration and knowledge sharing i.e. learning.The information for the studies was gathered at a major Swedish company from two projects. The projectswere carried out as cross-functional and possible key factors for cross-functional collaboration wasidentified.The results have been correlated with theories of Lean, Product development, Lean product developmentand Learning.

The study is based on Lev Vygotskijs and John Dewey's learning theory. Such is ?the zone for immediate development? and ?learning by doing?.Purpose: The study's purpose was to examine how four teachers´ work with bilingual children's language development in a preschool and in a preschool class. These questions will be answered in my study: 1). which view of bilingualism have been the educators? 2).

Problem: In society of today corporate competence is an important factor for survivor and development. IT is developing rapidly and can not be ignored by companies. Then need for people with IT-competence is conquent increasing. A survey of corporate IT-competence is therefore of interest for companies as well as for local authorities. To determine the IT competence within an organisation, this competence has to be measurable.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

The Anybus CompactCom modules are today using the Anybus NP30 processor. These modules are used for communication between industrial machines and larger network protocols. The communication loads on these systems are increasing every day and the limiting factor for the system is the processor.HMS, the company that develops the Anybus CompactCom, has shown interest for a benchmark test between the old processor and a new processor, ARM Cortex-M3. This project includes that benchmark. To be able to get results that reflect reality a test environment was created to simulate Anybus CompactCom conditions.

Product development cycles become shorter and shorter. The time from idea to market has become an important competitive factor. Despite this, methods used for making the product development process faster are surrounded with uncertainty about their efficiency. The purpose of the thesis is to describe the pros and cons of ?best practice? methods for shortening lead times and how these methods effect the lead times in research and development.

BAKGRUND: I andra delar av världen testas den fysiska kapaciteten hos yrkesverksamma poliser regelbundet. I Sverige finns inga tester eller krav på fysisk kapacitet på yrkesverksamma poliser efter genomförd grundutbildning. SYFTE: Att undersöka den fysiska kapaciteten hos poliser i yttre tjänst i Norrbottens polisdistrikt, för att påvisa om det finns ett behov av åtgärder för att upprätthålla yrkesaktiva polisers fysiska kapacitet. METOD: Förfrågan om frivilligt deltagande från poliser i yttre tjänst gjordes till delar ur Norrbottens polisdistrikt. Coopers test 2000 m och Harres test, vilka Polishögskolan använder i rekryteringsprocessen, valdes som mätmetoder.

This essay is the result of a case study. The aim of this study has been to gain an understanding of government employee?s opportunity to be involved in and contribute to the processes tied to organizational development. The case study is based on the perspective of the government employees and their experience and thoughts regarding their opportunity to be a part of the organizational development. The empirical data that was generated by the case study has been analysed with New Public Management and Sense Of Coherence as a theoretical point of view.

Arms trade is a multi-faced issue, it can increase the state's economic revenue; however also endanger the human security. The European Union's member state United Kingdom is one of the five largest arms traders in the world. The EU promotes human security in its work, especially in the union's development policies. These circumstances address the main question of the study: is there a contradiction between the UK's arms trade and the EU development policies. The objective of this study is to research the stately weapon use in three of the UK's trading partners, and how it could affect the EU development policies.

Swedish students' knowledge of both mathematics and reading comprehension has deteriorated in recent years. Scientists are discussing whether there is a connection between these areas and that the pupils deteriorating math skills may have something to do with their increasingly lower results in terms of reading comprehension. To investigate this possible connection, I conducted a survey among students in ninth grade and have come to the conclusion that the scientists are right: this connection absolutely exist. Students who received a high score on tasks designed to test students' mathematical problem-solving skills, also received high results on the reading comprehension test. And students who received a poor performance on the problem-solving tasks, were also low performers in the reading comprehension test.

My purpose with this paper related to my questions was to find out how professionals preeschool teachers working on multilingualism. I also wanted to get answers on how pedagogues in the preeschool may promote multilingual children´s language development, the factors that promote multilingual children´s language development and the role parents have in the language development of multilingual children. I chose to do my study in the form of interviews with professional preeschool teachers and interviewees described including the need for more knowledge of pedagogues around multilingualism. My result based on theoretichal background and the study is that pedagogues should let the children´s all languages esemble together. A factor influencing the multilingual children´s language development is ambient attitudes to multilingualism.

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

According to ?Fotförbundet" (2012), Overpronation occurs frequently (80 %) in the Western World and furthermore overpronation of calcaneus influences the position of the pelvic and thorax (Fotförbundet, 2012; Behnke, 2008). The aim of this study is to investigate whether or not it is possible to connect overpronation of calcaneus to the problem in the rider?s seat as observed by the instructors of Strömsholm. The study will also investigate if the riders seat problems as noticed by the riding instructors are comparable with the problems found by the analyst during testing. One purpose with the study is to raise the instructors and riders awareness that anatomical deviations in the rider might influence the rider?s position in the saddle. The questions of the study are: - Is it possible to see seat problems in riders with overpronation of calcaneus? - If it is possible to see more seat problems in riders with overpronation of calcaneus, do the instructors in the study considers the seat problems be similar with each other? - If there are seat problems in the study, is it the same according to the instructors and the analyst in human biomechanics? The hypothesis of the study is that overpronation of calcaneus has an effect of the rider?s position in the saddle. The study is conducted as a blind study where the test subjects have been filmed (from knees down) as they walked barefooted and later while riding.
