In gas turbine blade modeling a stable but yet flexible method of describing the blade shape is crucial. Polynomials and B ́ezier curves have previously been used and in this paper B-splines are employed instead. This method removes the need for many of the interior derivative conditions on the curve but special care must be taken when selecting the parameter values and appropriate derivative cond
The wide and increasing range of screen sizes between Android devices makes consumers use them very differently. Large devices (like televisions) are more suitable to view content and smaller devices (like smart watches) are to be used more as a quick controller of the main application. Distributed user interfaces is the concept of utilizing several of these de- vices in one application, so that e
The use of Islamic symbols in metal music has, until now, been a rare phenomenon. A few years ago, some black metal-bands in Istanbul started using Islamic symbols in both their artwork and lyrics, often in an anti-Islamic fashion. Although research on metal music is well established, little has been done on the relationship between black metal and Islam. This thesis explores the relationship betw
På Galgbackens vattenanläggning i Hässleholm tillämpas bassängsinfiltration genom återinfiltration av grundvatten i en isälvsavlagring. Syftet är att kunna leverera dricksvatten med god kvalitet till konsumenterna. Grundvattnet tas från brunnar i Ignaberga och Tyringe och återinfiltreras i isälvsavlagringen. Syftet med detta examenstarbete är att genom en spårämnesstudie undersöka uppehållstid ochGalgbacken water plant in Hässleholm is applying basin infiltration by re- infiltrating groundwater into a glaciofluvial deposit. The purpose is to supply drinking water with good quality to the consumers. Groundwater is pumped from wells in Ignaberga and Tyringe and re- infiltrated into the glaciofluvial deposit. The aim with this thesis is to examine retention and dispersion of the re- infiltrat
War-inflicted violence affects civilians in a larger proportion than combattants - where the majority of the victims are women and children. It is also men, who often are the planners of war, whom at the same time are expected to be the constructors of peace, where women and gender issues are neglected. In this essay we will challenge traditional assumptions about peace and security by adopting a
The primary focus on this thesis is to investigate different actors attitudes on sustainable forestry and opportunities and restrictions experienced with these. The actors already manage forest in some way, or are interested in managing forest sustainable. Sustainable development was defined during the WCED in 1987 and has since then been a concept for planning. The concept sustainable development
Föroreningar från metallurgiska processer som sprids genom skorstenar och ventilationssystem är ett välkänt problem inom metallurgisk industri. På senare tid har även spridning av föroreningar i form av damm uppmärksammats som ett problem. Föroreningarna uppstår troligen från diffusa källor, vilket innebär att de inte kan härledas till en specifik punktkälla. Detta arbete uppstod som en följd av aPollution in the metallurgical industry has been a well-known problem in terms of dispersal through stacks and ventilation systems. In recent times attention has been drawn to fugitive dust emissions as a pollution problem. This paper aims to illustrate important aspects to develop a method to control dust emissions. The method of this report consisted of a literature and an interview study. The r
This work relates to the proposed n-nbar experiment at ESS and covers a procedure with which future neutron research can be made using a small TPC prototype. Settings for the GEM amplification voltage supply and main drift field across the chamber have been established using minimum ionizing cosmic muons as a reference. To be able to reconstruct tracks in three dimensions and measure the deposited
The aim of this study was to examine businesses which use horses in various kinds of social work, and the opinions and experiences of the professional practitioners of these operations. I used semistructured interview to answer my questions, and I ended up interviewing eight people from seven different operations. Everyone was working in some kind of business which used horses as either an aid for
Syfte: Uppsatsens syfte är att kvalitativt tydliggöra och förstå skillnader i konsumenters lojalitetsgrad och köpbeteende, kopplat till service, mellan Generation Y och Baby Boomers och på så sätt bidra till service- och generationsforskningen. Metod: En kvalitativ studie med ett hermeneutiskt fenomenologisk förhållningssätt har genomförts. Forskningsansatsen är deduktiv med induktiva inslag. PrPurpose: The aim is to qualitatively distinguish and understand differences in purchase behavior and loyalty, related to service, between Generation Y and Baby Boomers and thus contribute to the service and generational research. Methodology: A qualitative study has been executed with a hermeneutic phenomenological approach. The research approach is deductive while also containing inductive eleme
The main goal of this project was to use the Modelica features on embedded systems, real-time systems and basic mechanical modeling for the control of a two-wheeled self-balancing personal vehicle. The Elektor Wheelie, a Segway-like vehicle, was selected as the process to control. Modelica is an object-oriented language aimed at modeling of complex systems. The work in the thesis used the Modelica
With global warming and increased uncertainty about future vehicle fuel supply, the need for fuel efficient vehicles is growing. In this Master Thesis, design and implementation of a control strategy for fuel efficient deceleration is presented. The resulting deceleration controller, implemented in Embedded Matlab and Simulink, provides autonomous deceleration functionality to a vehicle cruise con
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
I samband med att den nya vindkraftsprövningen trädde i kraft 2009 förändrades delvis kommunernas roll i vindkraftsutbyggnaden. Kommunerna som genom PBL tidigare prövade alla vindkraftsetableringar har numera inte möjlighet att pröva de vindkraftverk som tillståndspliktiga enligt MB. Däremot ska prövningen även fortsättningsvis lägga stor vikt vid den kommunala planeringen, varvid kommunerna kan s
Trash can harm both the environment and humans. It can maintain for a long time in the environment before degrading and during that time it can pollute soils and poison animals. This study focuses on the Pellekan campaign which started to reduce littering in the city of Mölndal. The campaign has been working the same way from the start in 2002 and now is time to evaluate how well it worked. For th
Previously developed methods to evaluate FED and FEC level via combination of CFD and evacuation simulation have been verified by new features of FDS6 and extended to fire cases involving common building materials. The FED levels calculated by the conversion factor [1] based on carbon monoxide are compared with the direct calculation by way of mass fraction of carbon monoxide, hydrogen cyanide and
Det är viktigt att ha en god energihushållning på grund av rådande klimatsituation och ökande energipriser. Det sätts även högre krav på inomhusmiljön i våra byggnader. En viktig faktor för att minska en byggnads energianvändning och samtidigt förbättra inomhusmiljön är att minimera luftläckaget. Eftersom att det de senaste åren oftare har satts krav på ett lågt luftläckage har nya produkter och m
Vår studie visade att det fanns ett samband mellan marknadsandel och lojalitet. Vidare vad gäller sambandet mellan lojalitet och priselasticitet samt pris och lojalitet hittades inget samband eftersom denna var väldigt svag.Our study showed that there is a relationship between market share and loyalty. Regarding the relationship between loyalty and price elasticity and price and loyalty, the study shows a very weak correlation. Thus the conclusion that there is no correlation .
