The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

Under 1900-talets senare hälft har lönesättning via enskilda lönesamtal, så kallad individuell lönesättning blivit den rådande lönebildningen i offentlig verksamhet. Tidigare utgick den offentliga sektorns lönebildning från löneskalor och tarifflöner, så kallad lönetrappa efter ålder och erfarenhet. Den offentliga sektorn kan anses vara en komplex organisation på grund av dess krav på demokrati, hushållande med samhällets resurser och tillämpande av offentlighetsprincipen. Dessa kan ha en påverkande effekt på hur lönebildningen ser ut samt den individuella lönens funktion som belöningsincitament och styrmedel. Syftet med detta examensarbete var att genom en intervjustudie med fenomenografisk ansats undersöka vilka uppfattningar som fanns ute i den offentliga verksamheten kring den individuella lönen och dess effekter.

Ditch cleaning is increasingly important in Swedish forestry. This study compare different concepts concerning machinery, namely two general-purpose excavators of different sizes, 8 tonnes and 15 tonnes, versus a dedicated machine constructed solely to deal with ditch-cleaning. The machines were tested on rough as well as on gentle terrain and on open terrain as well as in young stands in connection with thinning. The conclusions were that the excavators are more versatile and have greater capacity than the dedicated machine, while the latter excels in quality of work. Interestingly, there was no significant difference in performance between the both excavators..

In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..

Syftet är att beskriva och analysera VBM ochBSC samt diskutera möjligheten att integreradessa. Studien bygger på en kvalitativ metod därteoretiska begrepp inom Value BasedManagement och Balanced Scorecard analyserasoch jämförs med empiriska undersökningar iform av intervjuer. Kombinationen av VBM och BSC resulterar i ett lämpligt styrverktyg för många företag. Det är ingen perfekt kombination. Koncepten kompletterar dock varandra och ger en mer heltäckande bild av företagets verksamhet och strategiska möjligheter..

This thesis has its background in my curiosity of music and emotions. How can one find the technical way of bringing out emotions in music? I have worked with passages in music that I believe that the composer intended us as musicians to perform. This thesis presents a collaboration of three chamber musicians working with and performing Brahms Clarinet Trio, the first three movements. I?ve studied different theory analyses by several teachers and worked with the trio to apply it onto the performance and our interpretation of the work.

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.

Bakgrund: Med bakgrunden av företags behov att utvidga sin verksamhetssfär, har företagsförvärv blivit alltmer frekventa och mer omfattande. Speciellt i branscher med snabb utveckling såsom IT-branschen, är detta av aktualitet. Med förvärvsvågors uppkomst, har även ett stort antal av dessa förvärv resulterat i misslyckande snarare än expansion. Förklaringen till detta är mångfaldig och kopplas till områden kring före, under och efter förvärvet. Det som förväntas av ett förvärv, är synergieffekter, det vill säga förmågor av förvärvsobjektet som bidrar positivt till moderbolagets verksamhet.

ERP-systems have been one of the most important IT innovations in the past decade. The potential of a properly implemented ERP-system is great because it has got the ability to link the company?s different areas together. Despite its many advantages, there are several examples of cases where the acquisition and implementation has been a total failure.

In this report we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the performance of the approach, an operational transconductance amplifier is simulated. The circuit is modeled with symbolic equations that are derived automatically by a simulator..

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

Title: The Investment Savings Account ? Standard Taxation ? Right in TimeAuthors: Gustav Mårtensson and Erica Nordström LöfSupervisor: Göran HäggBackground: In order to facilitate and stimulate financial investments among privateinvestors the organization Aktiespararna made a proposal for a standard-taxed account. As aresult of this, the Swedish government decided to implement the Investment Savings Accountin January of 2012. The introduction of the Investment Savings Account implies that there arenow three different types of accounts for financial investments that are differently taxed onthe Swedish Market. Private investors can improve their after-tax results by combining AssetAllocation and Asset Location, according to earlier studies.
