This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.

A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

This thesis is about university spin-offs and the competition in high technology industries. In the light of efforts to increase the competitiveness of the European Union, an effective transfer of cutting edge technology from universities to the industry plays an important role. University spin-offs, start-ups founded to exploit academic inventions, are likely to face considerable market entry barriers. This is among other reasons due to high capital requirements for further technology development and lack of complementary resources. With a combination of relevant literature and empirical investigation, commercialisation of technologies within spin-offs is investigated and analysed.

Sweden is one of five nations in the world manufacturing fighter aircrafts. Highly advanced technology is needed in order to develop a fighter aircraft. When developing advanced technology, new applications, other than those initially intended occur, spin-off. Some of Sweden?s largest companies are spin-offs from the fighter aircraft industry.

Att produktion sker med hänsyn till människa och natur är viktigt för möbelföretaget KLONG. Detta har gett till följd att en ny kollektion av möbler utvecklats med fokus på knock-down. Vilket innebär att produkten är anpassad och konstruerad på ett sådant sätt att möbeln går att plocka isär och sammansättningen av produkten kan ske så nära slutkonsument som möjligt.Dessa produktionsförändringar får inte påverka produkten negativt så den förlorar sin identitet, möbelns formspråk ska uttrycka KLONG.Mitt arbete avser ett projekt där utemöbler har utvecklats åt KLONG utifrån krav på bl.a. produktion, distribution och funktion.Projektet påbörjades genom att utföra en grundlig analys av KLONG och deras produkter. Därefter utvecklades via designprocessen en flexibel knock-down möbel som via sin design förmedlar KLONG samt uppfyller sin funktion och innehar miljösmart distribution och tillverkning. .

Syftet med studien är att med utgångspunkt från tidigare forskning och teorier undersöka moderbolagets aktiekursutveckling i samband med nyhet om spin-off. Studiens fokus ligger på hur reaktionen ser ut på kort sikt. För att undersöka detta genomförs en eventstudie där fem olika tidsperioder runt nyhetens tillkännagivande studeras. Det framtagna resultatet kommer sedan att återkopplas till relevanta teorier rörande ämnet samt jämföras med tidigare utförd forskning. Sammanfattningsvis konstateras det att en överkastning uppstår under den studerade perioden [1998-01-01 - 2008-05-01].

This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart disease and hypertension) caused by environmental factors during development. This phenomenon is known as developmental programming. The purpose of this thesis was not primarily to answer any of the broader questions posed by this research project at large since this would require much more data than is reasonable to acquire over the course of a few months, but rather to evaluate the methods used in this project and reveal whether they are working the way they are presumed to. In the research project, which employs mice with the Grb10 gene knocked out as well as wild-type control mice, a dietary restriction model is utilized during gestation, which is supposed to generate offspring with lower birth weight and subsequent detrimental health effects in adulthood. This is supposed to be achieved by restricting the protein content of the pregnant mothers? diet to 9 % (as opposed to the control diet of 20 %) throughout gestation.

Kollisionen mellan två standardavtal benämns battle of forms och frågan blir om det finns ett avtal mellan parterna och vilka villkor som ska reglera parternas förpliktelser. De faktorer som anses vara av vikt är att lösningen bör vara förutsägbar, den ska innebära att parterna har en fortsatt avtalsrelation till varandra, den bör lösa tvisten snabbt och effektivt samt att den bör ta hänsyn till parternas egna krav och önskemål. Den svenska avtalslagens regler om oren accept innebär ett avtalslöst tillstånd mellan parterna och den svarar inte på vilka villkor som ska reglera avtalet. The last shot enligt art. 19 CISG innebär att det sist översända standardavtalet bli gällande på avtalet.

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

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.

By using univariate analysis, tobit and logit regressions, this thesis investigates determinants of asset writedowns. After controlling for variables indicating reductions in asset values, the results show that changes in senior management are significant in explaining the writedown decision and magnitude, which is in line with previous research. The explanatory power of changes in senior management has not increased with the transition to IFRS in 2005. No evidence is found supporting the hypothesis that the explanatory power of management incentives is higher for more discretionary types of asset writedowns..

AbstractThe use of standard agreements can hardly be overestimated in the society of today. The amount of standard agreements should barely decrease. One of the standard agreement?s main purposes, to make the concluding of the contract more effective, strongly agrees with the companies will to accomplish fast concluding of agreements using as small resources as possible A dispute that can arise in these contexts is that dissimilar standard agreements collide. Between nations this is called Battle of Forms.

Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.
