Akustik och säkerhet i inomhusarenor

The background to the study is that within the next ten years about 50 new multi-purposeindoor arenas will be built. These are used for various events such as sports, concerts, etc. In order to achieve a high level of security in the case of danger alarm signals and alarmmessages must be heard well by the visitors. ÅF-Ingemansson wanted to show builders the importance of good speech perception and that it is not observed in arenas today. They conducted technical tests on two large multi purpose indoor arenas to develop parameters that affect speech perception in the arena.To get a subjective view of how these arenas are experienced a survey was created.

Definition av stötdämpares fyllnadsgrad

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..

Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques

This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

Att mäta generell skam : En analys baserad på Raschmodellen

The purpose of this paper was to investigate whether Suzanne Retzinger?s linguistic cues for shame and verbal behaviors for hiding shame could be used to measure shame in surveys based on Thomas Scheff?s theory of shame. I created a measurement instrument consisting of 30 statements, which were all meant to measure general shame.The instrument was administrated to 180 respondents studying at Karlstad University, of whom 4 respondents were removed from the data set due to lack of standardization. With the polytomous rasch model used for the analysis, data from 176 respondents were analyzed, of whom 124 respondents were female and 52 were male.The result showed that the measurement instrument?s statements should not be used together because the analysis indicated multidimensionality.

Utveckling av Mätmetoder för Färdmotstånd

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Reference interval for urinary catecholamines and methylated catecholamines analysed using HPLC

Catecholamines are stress hormones that are produced and released by a rare tumor called pheochromocytoma. This tumor can cause hypertension which if undiagnosed and untreated leads to death. Since good therapy is available, it is important to find the tumor in time. The most common way to diagnose the tumor is measurement of the biochemical markers; catecholamines and their metabolites, methylated catecholamines.After observation that almost all normetanephrine results for women were higher than the upper reference limit and therefore pathological, the accuracy of the present reference intervals was questioned. Therefore new reference intervals for both urinary catecholamines and methylated catecholamines were developed by analysis of 46 samples using HPLC.

Konsekvenser av ny teknik på en sjukhusmottagning

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

Applicering av real optionsanalys vid beslut om flerbostadsrenovering - En studie av förutsättningar samt för- och nackdelar

Bakgrund och problem: I Sverige finns ett stort latent underhållsbehov av flerbostadshus. De fastigheter som uppfördes mellan 1961-1975 berörs i synnerhet av detta på grund av den tekniska förslitningen och den höga andel av den totala bostadsvolymen som dessa utgör. Att lönsamt renovera dessa fastigheter utgör en stor utmaning för fastighetsägare framöver. Idag utvärderas renoveringsprojekten inför genomförandet med hjälp av nuvärdesmetoden men det finns betydliga brister med denna. Följderna av detta är, bland annat, att de osäkerheter och risker som är kopplade till projekten inte värderas tillbörligt samt beslutssituationen upplevs som oklar.

A comparison between techniques for color grading in games

Color has been significant in visual arts for as long as the art-forms have existed. Still images and movies have long used colors and color grading effects to affect the viewer and characterize the work. In recent years attempts have been made to bring these techniques of stylizing also to interactive games. This dissertation aims to compare two different approaches of performing real-time color grading for games. Focus is put on examining the two ways from a number of different perspectives and from there draw conclusions on advantages and disadvantages of the approaches.

Hur fattas specifika utrikespolitiska beslut? : Externa hot och idéer i Clintons och Bushs Irakpolitik

The aim of this paper is to try to explain how specific, foreign policy decisions are made, and why one state decides to use violence against another state. A qualitative method is used, and text and documents are analysed. The two theoretical points of departure are central within foreign policy analysis: realism´s theories on external threats and constructivism´s theories on ideas´ policy influence. The empirical case chosen is the US decision to use military violence against Iraq. The paper investigates whether the real threat from Saddam Hussein´s Iraq was the cause of the American military attacks, or whether the ideas of leading politicians in the USA were decisive for the decision to invade the country.

Janus två ansikten : En studie om kökslärarens dubbla roller

This is a field study based on participant observations and interviews, describing the cooking teacher's complex everyday life. The school's restaurant is a unique arena, freely hovering between two worlds: The school world and the restaurant reality. Here, the students are confronted with real situations and problems, similar to the ones occurring in a restaurant, still having the school's safety net beneath them. It is for real, but still not, a bit like a flight simulator.It is on that arena the cooking teacher works, combining the two roles of the teacher and the chef. Two roles built on their own traditions and values.
