GPU accelerated SPH simulation of fluids for VFX
Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.
Utvärdering av lösningar för hårddiskkryptering
Information stored on unprotected computers that gets lost or stolen, and falls intothe wrong hands, can easily be accessed by moving the hard disk to a controlledcomputer, or by booting the computer from a removable medium, in order to getaround the operating system login. This is something that largely affects companieswhere customer information, trade secrets and other sensitive information can becompromised. A classic solution to the problem is encryption of individual files, but ithas some drawbacks as it puts a great responsibility on the users and unencryptedinformation can be left by mistake. A better solution to the problem is transparentencryption of the entire hard disk, i.e. that encryption and decryption of informationis performed automatically and without the user being affected.
Adderande tillverkning för metall
The Swedish automotive industry has since way back been struggling with bankruptcy, abroad buy outs and staff cuts. Competition and pressure on prices are two factors that affect the automotive industry. Because of this, the companies are pressured to continuously developing their work in addition to be able to compete on the market. The aircraft industry has successfully managed to implement additive manufacturing (AM) and for motorsport has several components manufactured with AM been used. When AM is used as a manufacturing method, there are a number of advantagesthat follows.
Intervention med tecken som alternativ och kompletterande kommunikation på en daglig verksamhet : Teckenanvändande av brukare med Downs syndrom och personal
Manual signs are an augmentative and alternative communication mode which enables and facilitates communication for persons with impairments in speech, language and hearing. There are different ways of teaching signs to persons with intellectual disabilities. One of them is milieu teaching, which is a method where the teaching takes place in natural settings. This method has proven to give good results in generalization and maintenance. Teaching signs to staff in groups has been shown to be effective.
Betydelsen av verbal uppmuntran vid utförande av handstyrketest
The purpose of this study was to evaluate if verbal encouragement had any influence on handstrength measurements. Twenty subjects participated in the study, all women between the age of 20 and 62 years. A standardisation of testing conditions and verbal encouragement were designed. Three measurements were conducted during two days using T.K.K 5401 Grip D. First there was a trial set, and then Test 1 (without verbal encouragement) and Test 2 (with verbal encouragement) were conducted.

PURPOSE: By analysing collected data using theory, we aim to interpret the design, implementation and the usage of BSC in NPO?s to be able to contribute to the research. METHODOLOGY: A case study design has been made through semi-structured interviews and backed up by a quantitative survey and internal documents. THEORETICAL PERSPECTIVES: Based on the sources given from the creators of the scorecard together with some sceptics and some followers, we have outlined the bases of balanced scorecard. To map out the non-profit sector and its strategic needs, the theories have tried to settle the specific need for the strategic tool given.
Konstruktion av fackla för biogas
Värmekollektor in Sunne is a company whose main occupation is to collect the gas produced inlandfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO2and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount aspossible used in different plants for example heating of households. But there are occasions when aflare is needed to burn the excess gas at standstills or testing of new landfills. The Flare only burns themethane to reduce the hazarder?s effect of the environment, it does not take advantage of the energy inthe gasThe goal of this master thesis was for me to create a foundation for an in-house production offlares for Värmekollektor.
Leveransprecisionsmätning : en företagsstudie på Sanmina-SCI
Performance measurements have become very important tools for companies because of ever increasing global competition in today?s market. Delivery dependability is one of the three most important performance measurements for companies to focus on and that makes this analysis, of the dependability, both very interesting and up to contemporary. In this rapport different aspects of delivery dependability will be dealt with, and a weight will be on what to measure and how to measure it together with how to present the outcome of the measurements. A discussion has also been held regarding what goal the company should have on its dependability.
Testikelstörningar hos hingstar i Sverige
This project was initiated by a veterinarian, that at stallion performance tests for breeding during a number of years, noted breed differences in various types of testicular disorders. Therefore it was of interests to examine the proportion of testicular disorders within certain breeds. The aim with the project was in a first part to study cryptorchidism in common horse breeds in Sweden. Information about castrations of stallions performed during a 10 year period (2000-2009) was collected from computerized case records at five animal hospitals. The case records showed the numbers of castrations, normal cases and cases preformed on stallions with cryptorchidism, abdominal respectively inguinal.
Solvärme på Utö
The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.
Minnesväskor och Per-Albintorp : En jämförande studie över Norrbottens museums och Jamtlis sätt att samarbeta med äldrevården
Denna uppsats handlar om hur två länsmuseer samarbetar med äldrevården. Anledningen till att jag valde detta ämne var att jag upplever att äldre personer och äldreboenden sällan diskuteras i litteraturen och undervisningen. Syftet med uppsatsen har varit att undersöka hur samarbetet mellan äldrevården och respektive museum ser ut samt att på ett mer teoretiskt plan undersöka vilka minnen som stimuleras och hur man kan koppla teman och föremål till Performance theory. Mina frågeställningar överensstämmer med syftet, de handlar alltså om hur samarbetet ser ut, vilka minnen museerna vill stimulera och hur man kan koppla teman och föremål till performance theory. Mina teoretiska utgångspunkter har således varit performance theory, teorier om personligt och kollektivt minne samt reminiscensmetoden.
Trombocyträkning hos katt : en ny metod
Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.
Referensintervjuer på folkbibliotek: En intervju- och litteraturstudie
This thesis examines the subject of reference interviews and the ways librarians form an opinion of users information needs. Using literature and interviews with three librarians I look at the questions below: - Why and when are reference interviews needed? - What significance do they have? - What ideas exist about the performance of reference interviews? - Are there any differences in librarians views of the questions above compared to views in the literature? Results from literature studies and interviews show that reference interviews can be important when librarians try to find out more about users information needs. However its neither necessary nor possible to analyse all reference questions. Librarians therefore need to determine if a reference interview is needed or not.
Hedge Fund Style Analysis, Is an Index-Based Approach Viable?
This thesis aims to open the Pandora?s Box of hedge fund styles through an index-based style analysis. This information asymmetry is due to both less strict disclosure requirements and inherent nature of hedge funds. We employ a multiple unconditional linear regression model wherein 23 Swedish hedge funds are regressed on 10 style indices. In addition to the increased interest in hedge funds and their performance drivers, our unique approach with regressing return on return motivates this study.
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.
