Further, the aim is to discern specific store image attributes captivating Swedish and Danish consumers.

FPGA baserad PWM-styrning av BLDC-motorer

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Optimal bredbandig vågform framtagen genom generaliserad osäkerhetsfunktion

The waveform of a radar signal affects the resolution in velocity and distance. The ambiguity function is used as an aid for analysing narrow band radar signals simultaneously in time and frequency. An analysing tool for wide band radar signals is missing.This thesis describes a generalised ambiguity function to be utilised for study of wide band signals. Waveforms are further synthesised with help of the developed analysing tool. The aim is to start with a certain ambiguity function and find a waveform that reproduces the same ambiguity function.Mathematical formulas are presented and implemented in Matlab to produce the wide band ambiguity function.

Språkets inverkan på matematikinlärning hos tvåspråkiga elever

Skilda meningar råder om modersmålets roll i undervisningen. Syftet med studien var dels att undersöka hur elever använder modersmålet (bosniska) respektive svenska språket vid matematiska problemlösningar samt i vilken utsträckning modersmålet används i matematikundervisningen. Undersökningen var kvalitativ och metoderna som användes var observationer samt intervjuer av ett antal elever. Resultatet visade att de flesta eleverna har ett utvecklat vardagsspråk men saknar matematiska begrepp på båda språken..

Scrum som möjliggörare för kunskapsöverföring? : - en studie om kunskapsöverföring mellan utvecklare på ett mjukvaruföretag

Kunskap är som mest användbar när den har inflytande och delas med andra varför medarbetarna inom en organisation bör ha möjlighet att lära av varandra. Då en individ delar eller sprider sin kunskap och erfarenhet till någon annan benämns det som kunskapsöverföring.Syftet med denna studie är att undersöka om och hur kunskapsöverföring mellan utvecklare möjliggörs när en organisation inom mjukvaruindustrin använder Scrum som arbetsmetod. Studien avser även undersöka huruvida metoden på något sätt hindrar kunskapsöverföring. För att besvara syftet ställs följande huvudfråga: Hur möjliggör Scrum kunskapsöverföring mellan utvecklare? vilken består av tre delfrågor: (i) Var sker kunskapsöverföring i Scrum? (ii) Vilken typ av kunskap sprids i Scrum? (iii) Vad kan hindra kunskapsöverföringen då Scrum används som arbetsmetod?Med utgångspunkt i teorier om kunskap, kunskapsöverföring och kontexten för kunskapsöverföring samt den teoretiska beskrivningen av Scrum utformades en analysmodell som visar Scrums förväntade stöd för kunskapsöverföring.

Effekter av spädningsvätska på motilitet och fertilitet hos hingstsperma : en jämförelse av subjektiv motilitetsbedömning och QualispermTM

At SLU, Divison of Reproduction, Dept of Clinical Science, there is an ongoing project on the development and evaluation of new methods for the assessment of stallion semen quality. This EEF-study, which is a part of that larger project, has focused on the effects on motility and fertility of stallion semen of two different extenders and selection. Both an objective method and a subjective method for analysis have been used and compared in the study. The increase in the use of artificial insemination with cooled semen in Swedish horse breeding over the last decade is thought to play a part in declining foaling rates (Kareskoski et al, 2006, Kuisma et al, 2006). This calls for better evaluation methods of semen quality since cooling and transportation put higher demands on semen quality in order to maintain fertility (Aurich, 2005).

Internprissättning : Två perspektiv på "rätt pris" utifrån armlängdsprincipen

Internprissättning är vanligt inom dagens koncerner och växer mer allt eftersom världshandeln har globaliserats. Användandet av internprissättning för att öka vinsten är en diskussion som tog fart redan på 1950-talet. En diskussion som baserats på att bolag medvetet förbättrar sin skatt genom de olika metoderna som finns. Ett utnyttjande av regleringars brister och otydliga tolkningar. Ämnet är speciellt då det kräver kunskap inom både företagsekonomi och juridik.

Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

Akuta effekter av assisterade hopp på kvinnliga idrottares hoppförmåga

Vertical jumping ability is an essential skill in many sports. The aim of this study wasto investigate the acute effects of assisted jumps on subsequent countermovementjump (CMJ) performance by female athletes. Nine healthy, trained female subjectsvolunteered to participate in the study. In a randomized order, they performed oneregular warm up protocol before testing their CMJ baseline value, and one warm upprotocol with an addition of five assisted jumps at 30% body weight reduction beforeanother CMJ test. Elastic cords attached to an overhead pulley system and to aharness around the subjects' upper body were used to reduce the body weight.Significant improvements were noted in jump height, 2.3 cm (7%), positive forceimpulse, 4.7 Ns (2%), vertical take off velocity, 0.1 m/s (3%), countermovement time,0.1 s (12%) and breaking time, 0.1 s (14%), p.

Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
