This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

 AbstractA walk at Karlstad's cemetery and burial - grounds is like a strolling in an architectural park with trees, bushes and flowers. But these parks are different; they are filled with dead people, their memorial stones and their life stories. This world is full of socially, economically and culture differences from different times from 19th century till today's society. The cemetery - and burial - grounds in Karlstad can tell you about 19th century influences just by looking at the stones and where they are placed. Influences from the religion, the Christianity, which symbols for example is the cross, the birds and the sun that rises or falls, but also phrases that is directing to the bible.

Syfte ? Studiens syfte är att undersöka hybridapplikationers prestanda i olika situationer för att ta reda på varför de upplevs som långsamma. För att uppnå syftet besvaras följande frågeställningar:Hur presterar hybridapplikationer jämfört med nativapplikationer beräkningsmässigtÄr JavaScript-biblioteken anledningen till hybridapplikationers sämre prestanda, och vilket av de bibliotek som undersöks är det mest lämpade för bästa prestanda?Kan hybridapplikationer hantera stora datamängder med IndexedDB utan att bli oresponsiva?Metod ? Studien använder sig av en experimentell forskningsmetod där hypoteser och förutsägelser formuleras och sedan testas för att besvara frågeställningarna.Resultat ? Resultatet från studien visar att prestandan för mobila hybrid-applikationer är i de flesta fall, vid utförande av samma uppgift, underlägsen den för dess motsvarande nativapplikationer. Resultaten visar även att prestandan påverkas av vilket JavaScript-bibliotek som används men att biblioteken inte är anledningen till hybridapplikationers långsamma prestanda.

The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..

Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. This cross-sectional study was conducted to establish and compare the sero-prevalence of the tick-borne pathogen Babesia bigemina among randomly selected Ankole Long-horned cattle and European crossbred cattle on 30 farms in Kiruhura district, in two sub-counties near Lake Mburo National Park in South-western Uganda. Half of the farms were situated in close proximity to the park and thereby housed cattle with more frequent wildlife-livestock interface (Sanga), whereas the other half had less frequent contact (Kikatsi).

In order to answer the question in the title, a cross-cultural analysis of two countries was done. Countries chosen were the Republic of Latvia and the Kingdom of Spain. The need for this research was suggested by increased cross-border business activities inside the European Union, and the lack of previous studies involving new Member States. The aim of the research was to see what environmental factors influence advertising adaptation in the European Union, as well as to evaluate the applicability of a standardisation approach. According to the theory, there are three external factors that influence the creation of a global advertising.

The aim of this thesis is to create an understanding about how and to what extent a Swedish expatriate manager needs to adapt his/her leadership in accordance with the culture of the host country. Thus shall different managers? perceptions of experienced management overseas be studied. To accomplish our aim, three different problems have been designed. These are as follows: In what way does the manager?s earlier experiences and knowledge about expatriation affect her or his leadership in a new cross-cultural context? How does the culture of the host country affect the expatriate manager?s leadership? How does the expatriate manager handle contradictory demands: that is differences in expectations from subordinates and the higher management? We have chosen to use an abductive approach in order to do a qualitative study and we have therefore conducted eight case studies to create a foundation for distinguishing patterns.The case studies are based on eight Swedish managers with experience from expatriation. The theoretical framework is structured upon three main themes including; knowledge and skills a global leader needs to possess, the relation between the leader and subordinates, and contradictory demands.

In this report, the risk of cracking in joints and/in adjacent concrete is estimated by checking shear forces in joints and the ratio between the actual maximum principal stress ant the actual strength of the concrete. The shear force has been estimated both by simple methods as well as by two-dimensional calculations. The risk of cracking in the concrete and/or in the joints is estimated with the computer program ConStre. The restraint from a resilient foundation or rock on a young concrete construction is estimated by a simple method that is exemplified. It is shown that the restraint can be neglected in some cases.

Background: The environment and the design of auditing regulation can vary significantly between countries, which can affect the form, content and quality of the audit report. The purpose of the International Standards on Auditing, ISA, is to facilitate the work for auditors on an international basis. Sweden today follows the RS 600 which is based on ISA 600, which contains standards for when an auditor use work performed by other auditor. In October 2007, came a revised and redrafted version of ISA 600 that will be enforced in Sweden in the audit of the financial year beginning on 1 January 2011. To what degree the new requirements will affect the group audit is clearly dependent on how the reporting, evaluation and instructions between the group auditor and other auditor has been carried out previously.Aim: The aim with this paper is to explain the reporting between the group auditor and other auditor in an international corporate group.

Majoriteten av idrottsskador inklusive skada på främre korsbandet (Anterior Cruciate Ligament, ACL) uppstår i slutet av träning/tävling när personen tenderar att vara trött. Nuvarande funktionstest inför återgång till idrott efter skada utvärderar ofta individens hoppförmåga i ett icke-uttröttat tillstånd.Syfte: Syftet med följande studie var att se huruvida prestationen i två olika enbenshopp kunde skilja sig mellan före och efter 25 minuters löpning, varav 15 minuter på hög-intensiv nivå och om hopprestationen skiljer sig mellan oskadade och ACL-opererade kvinnor.Metod: Totalt deltog 8 friska kvinnor, utan pågående besvär från nedre extremitet samt 6 färdigrehabiliterade ACL-opererade kvinnor som återgått till sin tidigare aktivitetsnivå. Deltagarna genomförde tester vid två olika tillfällen. Ett Pre-test-tillfälle då inträning av distans- och cross-overhopp samt ett max-pulstest (HRmax) på löpband utfördes. Ett Test-tillfälle där respektive hopp utfördes före och efter cirka 25 minuters löpning varav 15 minuter var på hög-intensiv nivå (>RPE 15 eller >85 % av HRmax).

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.
