Förbättring av mjukvarubibliotek för parallellberäkningar med programmeringsmodellen Chunks and Tasks

Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.

Modellering och simulering av det evaporativa bränslesystemet i en personbil

This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

Elektrifiering av jordbruksmaskin : Direktkoppling till solföljare och elnät

The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.

Utvärdering av produkter för säker autentisering i Windowsmiljö

In this report hardware based alternatives to password authentication in a Windows domain are evaluated for the needs of a certain company. In order to investigate the demands on such alternatives interviews with people concerned have been carried out. The demands which resulted from the interviews have been used to select types of hardware tokens for evaluation. Two products which offer authentication with smart cards and USB tokens have been selected and closer evaluated. These are RSA Passage which offers both hardware options and Rainbow iKey which uses USB tokens.

Folk i allmänhet har taskig smak En studie av vanliga läsares kvalitetsvärdering av skönlitteratur

The aim of this study is to investigate ordinary readers' evaluation of quality in literature. The main issue is which criteria ordinary grown-up readers use when they are defining their likes and dislikes in literature. The analysis is based upon qualitative interviews with six readers, two men and four women, between 21 and 59 years of age. The study is hermeneutic. Since theoretical works concerning evaluation of literature among ordinary readers are sparse, the philosopher of arts and religion Hugo A.

Nyckelfaktorer vid exportetableringar i Tyskland : - En studie gjord på fyra norrländska företag

A common assumption in marketing is the wider variety of product a corporation has, the better for the consumer: more product - more choices. Companies often develop a line extension to broaden consumer range through product attributes including quality, function and design. These developed attributes within the product are not always optimal for the consumer. As a result, companies often become entangled in having a price higher than the cost and benefit of the products. This essay aims to analyze the consumer value of line extension products and how these evaluations relate to extended line product pricing.

Att mäta publicering av artiklar: En tillämpning av bibliometri på evidensbasering inom socialt arbete

This thesis examines the scientific publishing in the subject area of evidence based practice EBP in social work. Issues are: How has this publishing evolved, separately and compared to the publishing about evaluation in social work? What authors/countries have produced the largest numbers of articles? What journals have published the largest numbers of articles? Which are the most frequent co-occurrences of a selection of terms? 161 records for articles from 50 different journals were selected from Social Services Abstracts using subject of journal and a query as criteria. For each year, the number of articles about evaluation in social work was larger than about EBP. A decline in the publishing about evaluation coincide with a growth in EBP after the year 2000.

Varelsedesign : en metod

My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.

Spenarnas kondition i automatiska mjölkningssystem : en studie av två spensprayer

Two post milkning teat dips (PMTD´s) were compared in an automatic milking system at Kungsängen Research Farm, owned by SLU (Swedish University of Agriculture) in Uppsala. In the experiment an evaluation system was used where teat condition regarding skin and teat ends was graded according to a scale where 1 was the best score and 5 the worst. The evaluation period was almost six months in total devided into four minor experimental periods. The technician scoring the teats did not know which PMTD that was currently used. Statistical analysis showed a significant difference between the two PMTD´s regarding teat skin condition, but not regarding teat ends.

Musik och kommunikation - en kursutvärdering

ABSTRACT Bjelkenbrant, Pernilla, 2007: Musik och kommunikation ? en kursutvärdering (Music and communication ? a course evaluation) The purpose of this study is to do a quality assurance of the course ?Music and communication? (MUPR1205) as it was implemented in a class of music students at the program of Arts and Culture at Törnströmska upper secondary school in Karlskrona during 2006/2007. The overall question is to what extent the shaping of the course involves the attainment of the values and goals formulated in the national school documents. The study includes an interpretation of course goals related to overall goals, and a suggestion of how theories of the relationship music ? society can be applied to those goals to make a successful course structure.

Dammsäkerhetsanalys via stabilitetsberäkningar för Långströmmens kraftverk : En jämförelse mellan olika dimensioneringsmetoder

A detailed dam safety evaluation (in Sweden called FDU) was performed in 2009 by WSP where stability control was performed for Långströmmen power plant with associated spillways. This evaluation concluded that stability could not be ensured, and risk of sliding occurred. The evaluation is based entirely on the recommendations outlined in RIDAS, the power companies guidelines for dam safety, and it is clear that extensive renovations are necessary to stabilize the dam.In this work, the stability will also be checked with guidance through new proposals on guidelines for concrete dams sliding stability, ELFORSK?s report 08:59. This report considered the guidelines in RIDAS as oversimplified, both from an international perspective, but also with regard to the current state of knowledge regarding dam safety.

Konditionstester i rehabiliteringssammanhang : - En litteraturöversikt

During the past few years there has been an observed decrease in physical fitness within different patient groups. As a part of the rehabilitating physiotherapy treatment it is important to acknowledge the physical condition of the patient. Physical fitness testing might be difficult due to physical limitations within different patient groups. A broad range of exercise tests is therefore of importance in clinical practice. The aim of this overview was to describe exercise tests used in rehabilitation contexts, and to define areas of use and restrictions.

Utvärdering av olika metoder för framställning av höjdkurvor från laserskannade höjddata

Lantmäteriet (the Swedish mapping, cadastral and land registration authority) has been laser scanning Sweden since 2009. From the laser scanned data a digital elevation model (DEM) in grid format, with a resolution of 2 m, is produced. This DEM is called GSD-Höjddata, grid 2+ and from its data and the laser point cloud itself (in the form of a las-file) contour lines can be extracted. Lantmäteriet has not yet done this, but plans to update the contour lines in their cartographic products exist. If this is to be done in a satisfactory way an evaluation of different methods for it is needed.

Scoutförskola : En förskola med scoutprofil

Due to the interest of starting a preschool with a scout profile in my circle of acquaintances I chose to write my report about how the scout method would work in a preschool. I did this by comparing the origin of scouting and preschool. I based my report on the following questions:Are there any similarities or differences with curriculum, education act and the scout method that can make it easier/harder to work with the scout method in the preschool?There are many theorists that have had influence on the preschool. Give some examples of their theories that could affect the scout preschool?What is the difference between a teacher and a scout leader?What would a preschool look like if you included the scout method in the daily activity?With the help of my literature studies I compared the scout method against the laws and rules to make sure that the scout method doesn?t contradict them.
