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..
Vad säger bilden?: En utvärdering av återvinningseffektiviteten i ImBrowse
The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.
Inneklimatundersökning : Hur fungerar ventilationssystemen i två större lokaler och hur ser kommunikationen kring detta ut mellan hyresgäster, hyresvärd och projektör?
This examination paper is a study of the indoor climate in a theatre and a practice room for orchestras placed in Sickla in Stockholm. The designer of the ventilation system wondered if he had managed too make a good environment for the users and he also wondered which of the rooms that had the most desirable climate. The project includes polls for visitors, interviews of people connected to the rooms and measurements of the physical environment. The results show a small dissatisfaction about the thermal indoor climate, it?s a little bit to cold and the air draws.
Bonus och ägarskap i svenska storbanker
In this master thesis we are trying to investigate whether the heads of the four major Swedish banks are receiving compensation because of their own performance. We have investigated a number of parameters in the reporting and compensation description of Handelsbanken, Nordea, SEB and Swedbank and compared it to macro data.We have used publicly available information from the banks as well as macro data from 1998 to 2009.We have come to the conclusion that the revenue and profits of the banks are heavily influenced by external factors and that there does not appear to be a clear link between a CEOs actions, the reported results for the bank, the shareholder gains and the compensation for the CEO. It appears as if the bonus payments to a CEO may depend more on parameters beyond the CEOs own control than the performance of the CEO..
Från Värendsvallen till Arenastaden : En studie om Smålandspostens nyhetsrapportering angående uppförandet av fotbolls- och ishockeyarenorna på Värendsvallen och Arenastaden i Växjö
The following essay is a study of the theatre-play Min Arm, a translation and performance by Per Lasson for Fria Teatern in Stockholm 2009-2010. Actor, director and playwright Tim Crouch wrote the original script My Arm in English in 2003.With basis in intermedial theory, as defined by Jörgen Bruhn, as well as Hans-Thies Lehmann?s theory on post-dramatic theatre this study investigates the meaning-building processes in Min Arm as a theatrical performance. Concepts of the difference between stage play and performance text are borrowed from and inspired mainly by Eli Rozik?s Generating Theatre Meaning.
Implementation av ett kunskapsbas system för rough set theory med kvantitativa mätningar
This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g.
How do you measure culture? -A case study of result control within the Gothenburg Opera
Problem The culture sector is characterized by qualitative goals which raise questions such as how do you measure culture and what is ?good? culture? Both the goals and the measurements tend to result in subjective judgments, which according to the theory make result control inefficient. Yet, result control is frequently used in the culture sector; which leads up to our research question: What characterizes the problems of result control in the culture sector?Purpose The aim of this study is to make a survey of how the Gothenburg Opera works with result control and follow-up. By defining how it tackles the different problems, which could arise with result control in a non-profit organisation, we aim to map how the problems regarding result control are characterized in the Gothenburg Opera.
Mål- och resultatstyrning inom domstolsväsendet: En fallstudie inom Migrationsdomstolen i Stockholm
The aim of this study is to enhance the knowledge of target and performance management?s effects on the judiciary. In the past decades there have been a number of reforms in the general public sector of many countries. The management philosophy often used to describe these public sector reforms is called New Public Management (NPM). One main theme has been an increased focus on the management control systems, for example a greater emphasis on target and performance management.

C, C++, Java och Python - En prestandajämförelse mellan fyra programmeringsspråk
In today?s society computers are getting a much more important role. To get a
computer to work
as intended it has to be programmed. A computer program is written with
programming
languages.
There is an abundance of programming languages available today and there are
many
differences and similarities between them. The different languages have their
advantages and
their disadvantages where some of them are intended for fast performance, some
to be cheap
on memory usage, and some are developed to be easy to program on.
In our thesis we have chosen to compare four of todays most common languages,
C, C++, Java
and Python.
Utveckling av ett hjälpmedel för träning och utvärdering av förare av tunga fordon
The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.
