Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..

Hur ser barns yttranden ut? : Yttrandetyper, bisatser och yttrandelängd hos svenska 3- och 4-åringar

Children?s utterances have been studied in different languages; however, only a few studies refer to Swedish. The aim of the present study is to describe utterance types, subordinate clauses and utterance length for a group of three and four year old Swedish children without known functional impairments.The study included 29 children, 17 girls and 12 boys, in a larger city in the south-east of Sweden. The children, all native Swedish speakers, were aged 3;0 to 4;11. Sound recordings were made during a playing session with one of the authors in the children?s day care centers.The utterances were divided into the categories elliptical responses, incomplete and partly unintelligible utterances, imitative utterances and independent utterances.

Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank

The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.

Ersättningsnivåer - En studie av fast och rörlig lön till verkställande direktörer i svenska börsnoterade företag åren 2001 till 2005

Background and problem: Whether or not the pay to executives is fair is widely debated. During the last years especially the variable pay has been in the spotlight. But at what levels are the compensations really at? Media?s focus is mainly on the absolute highest compensations which may result in a skew view on pay-for-performance incentives.Purpose: The purpose of this thesis is to establish the levels of compensation to executives in a wide range of randomly selected companies listed on the Stockholm stock exchange during the years 2001 to 2005. Furthermore, the impact of a set of firm specific variables on compensation levels will be analyzed with basis in several hypothesis.Delimitations: The variable pay considered in this thesis will only be variable cash bonuses.

Musik och Film : Ett möte mellan två konstformer i Stanley Kubricks ?2001 ? a Space Odyssey? och Woody Allens ?Manhattan?

Filmmusic is often composed specially for a film. When analyzing film-music it seems very common to study the function of the music in a narrative context in order to see how it cooperates or relates to this narration. In the present thesis I am investigating the interaction between film and music as two ingredients on an equal level. In short: what happens when a filmmaker chooses music that has already been composed for another occasion, even in another time and a different cultural context? My aim is twofold: first to examine current film analytic strategies, secondly to find new ways of comprehend pre-composed music in relation to its new setting in a film.

MATSVINN FÖRSVINN - En kvantitativ studie om hur ett CSR-argument kan involvera konsumenten i kampen mot matsvinn i butik

Every year 67000 tons of food is wasted by Swedish retail stores. The waste implies financial losses for the retailer and it has a huge impact on the global environment. Reducing in-store food waste is thus a win-win situation for both retailers and society. The most effective way to reduce waste is primarily by optimizing the logistics of supply, but customers expect a store with a wide range of products and stuffed shelves. Thus there will always be products about to expire.

Inställning av automatikermed spänningsreglerande verkani det sydsvenska 400-130 kV nätet

The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.

Kombination av egna och etablerade varumärken - Ett företags liv eller död?

Konkurrensen i klädbranschen växer och blir allt intensivare. Det krävs idag mer från ett företag för att kunna skilja sig från mängden. En rad olika faktorer påverkar en konsuments beteende och attityd gentemot ett företag och en butiks val av varumärken och sortimentsutbud spelar en betydande roll för att kunna kommunicera ut ett budskap som lockar den tänkta målgruppen. Det blir allt vanligare att detaljistföretag som erbjuder etablerade varumärken integrerar bakåt och producerar egna märkesvaror. Lager 157 är ett företag som på senare tid har följt denna trend.

Gäller den mångkulturella skolan även för lärarna?

Med denna uppsats har vi närmat oss ämnet ?den mångkulturella skolan? ur lärarens perspektiv. En mångkulturell skola tolkas ofta som en skola med elever från många olika kulturer. Tyvärr glöms ofta de utlandsfödda lärarna bort. Syftet med denna studie är att undersöka utlandsfödda lärares uppfattningar om sin roll i den mångkulturella skolan.

Lag i katolsk och luthersk teologi : Om lagbegreppet i Wolfhart Pannenberg, Dietrich Bonhoeffer, David P. Scaer och Johannes Paulus II encyklika Veritatis Splendor

Three main questions give the fundamental structure for this master thesis: 1) In what way is the notion of law being perceived in the following theologians respectively; David P. Scaer, Dietrich Bonhoeffer and Wolfhart Pannenberg? 2) In what way is the notion of law being perceived in the encyclical Veritatis Splendor? 3) Which similarities and divergences can be found in the respective expositions of the notion of law?For the purpose of comparison, I have employed four questions of analysis. These are: A) What is ?the law?? B) Is the law being effected, or is it working, in the world and if so - in what ways and for what purposes is it meant to serve? C) Does human beings have any capacities to understand and/or live in accordance to the law? D) Does the Gospel, perceived as the earthly life, actions, death and resurrection of Jesus Christ, effect any alteration with respect to the purpose, range, function or interpretation of the law?In order to better understand Roman-Catholic concepts of law, the treatise on law of Thomas Aquinas Summa Theologica is briefly presented.

Avtalslicensens förhållande till konkurrensrätten : När strider utövandet av en avtalslicens mot konkurrenslagstiftningen?

AbstractCopyright is designed to not interfere with society's general and overriding interest of effective competition. An effective market competition benefits consumers by lowering prices, raising the quality and expands the range of goods and services.The purpose of the paper is to investigate if the collecting societies licensing violates competition laws. On the basis of the investigation regarding the bill for a new Swedish copyright law (URL), mainly the new wording that regulates the license agreement, corresponds to the EU competition rules and customs within the area.The collecting societies licensing violates the competition laws in the following cases? Discrimination of members because of nationality?           Authors transferring their sole rights to global exploitation?           The collecting society have the right to manage the rights after the author have left as a member?           Users that are established abroad do not get access to the repertoire of  the collecting societies, the same goes for concerted practice if this is the purpose or result?           Parallel behaviours that cannot be explained objectively?           Dividing the market?           Fixed Prices?           Refusal to sign multi-territorial licenses?           Apply different conditions for equivalent transactions resulting in competition disadvantages for a company that cannot be justified by reasonable causesCurrently there are no indications that the new bill to a new URL violates EU law. The author of the paper thinks this may change if the collective management extends, so that other member states get the extended license agreements, then the single market is affected by the competition restriction that the new bill to the URL mean.
