Spridning av bekämpningsmedel i banvall : Modellutveckling och känslighetsanalys

The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

Flödessimulering: ett standardiserat arbetssätt

Volvo Construction Equipment AB Components Division i Eskilstuna är mitt inne i ett omorganisationsarbete där fabriken byggs om från funktionsverkstad till flödesorienterade grupper detta för att effektivt möta den växande orderingången. När gruppernas värdeflöden tydligtgjorts återstår ett intensivt arbete med att optimera ledtider, lagernivåer och produkter i arbete med mera. Ett kraftfullt verktyg för att stötta detta arbete är diskret händelsestyrd (DE) simulering. Det har genomförts flertalet DE simuleringar tidigare på företaget, då främst av konsulter. I den nya fabriken finns en önskan om att utföra detta arbete själv.

Verifiering av beräknad energiprestanda för flerbostadshus byggda år 2007-2009

The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.

Mellanskog medlemmars och medarbetares inställning till SMS och e-post : en fallstudie

Communication, information and marketing are three of the main prerequisites for companies that want to increase their turnover. The everyday work for a Forest Manager within the forest owners? association Mellanskog consists to a large part of interpersonal communication, either by close vicinity contact or by phone calls. Interpersonal communication is time consuming and resource intensive. If the flow of information, communication and marketing does not function well then there is a lack of a base for development.

Isometrier i Poincarés halvplansmodell

SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

Utveckling av Prisjakts butiksomdömessystem

This thesis work is the result of the company Prisjakt?s wish to develop and improve its current system of opinions for online stores. The challenge was to develop a similar system that competitors are using but better. The collection of information is based on purchases and are collected from Web-shops. The purchases can then be monitored in a control panel.

Termomekanisk utmattning av Sanicro 25 : Materialmodellering med finita elementmetoden

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

Inbäddade kartor för geografiska presentationer på webbsidor

This is a survey of different techniques that may be used for embedding geographicdata into web pages. Different models of GIS communication are examined and a testsubject in the form of an application is implemented and evaluated.The test application (?StudentKarta? eng. ?Student Map?) lets students submit theirresidential data and shows their position as pins on an embedded Map.An expire date is used to let the pins fade away and disappear.The application uses the popular Google map engines to display the geographicalpresentations.

Tamillern : beteende, hantering och omvårdnad

This essay is intended for veterinary nurses and its purpose is to contribute to an increased knowledge about the ferret and there by a better nursing care at clinics. The essay discuss in briefness origin and earlier use of the ferret but also anatomy, physiology and reproduction. The senses of the ferret, as vision and hearing, are described in connection with behaviour. The part of the essay where nursing care is described bring up procedures as handling when collecting blood, medical techniques and how the clinic best should be suited for these animals. The main part of the essay is based on literature studies but it also contains a study visit at Blå Stjärnans animal hospital in Göteborg. 23.

Implementering av Patientsimulator för Anestesimaskiner

In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Implementering av 1D-DCT

IDCT (Inverse Discrete Cosine Transform) is a common algorithm being used with image and sound decompression. The algorithm is a Fourier related transform which can occur in many different types like, one-dimensional, two-dimensional, three-dimensional and many more.The goal with this thesis is to create a fast and low effect version of two-dimensional IDCT algorithm, where techniques as multiple-constant multiplication and subexpression sharing plus bit-serial and bit-parallel arithmetic are used.The result is a hardware implementation with power consumption at 19,56 mW..
