Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..

På några år har användningen av IP-telefoni inom svenska företag tredubblats och vi börjar nu se ett attitydskifte gentemot en teknik som länge dragits med dåligt rykte på grund av kvalitetsbrister.IP-telefoni är ett resultat av att data- och telefonikommunikation vävs samman och att kapaciteten i nätverken ökar. Detta medför att man genom att införa IP-telefoni kan genomföra kostnadsbesparingar och effektivisering. Men tekniken erbjuder även ökad funktionalitet och därmed även mervärde för organisationer som använder IP-telefoni. Inser organisationer detta och utnyttjar man fördelarna med tekniken för att skapa acceptans inom organisationen?Syftet är att undersöka vilka faktorer som motiverar en övergång från kretskopplad telefoni till IP-telefoni, och hur man inom en organisation skapar acceptans för den nya tekniken.Syftet har uppfyllts genom en kvalitativ studie som byggt på semi-standardiserade intervjuer.

The Uppsala based company Q-linea develops procedures, instruments and systems for protein and nucleic acid analysis. The components in such an instrument are controlled by microcontrollers. Microcontrollers are computers in one singular chip that can be used in a wide range of applications such as cars, toys or in this case an analysis instrument. When developing a new instrument for biochemical analysis, Q-linea needed new software for controlling and communicating between the components in the instrument. The process of developing this software is the subject of this thesis.The project included research of microcontrollers and the components in the instrument.

This report is focused on marketing opportunities for small-scale mango farmers in the Nyanza Province in Kenya. Kenya is a large horticultural producer in the world. Horticulture is an important income for a large share of the rural population in Kenya but profitability is low due to inefficiencies in marketing systems and poor infrastructure. The conditions for growing mango in the Nyanza Province are very beneficial and there are two harvesting seasons. Mango offers good income opportunities for small-scale farmers in the Nyanza Province.The aim of this study is to identify marketing conditions that will enable prospering business for small-scale mango farmers in the Nyanza Province, Kenya.

In this composition, a study of consignment inventory on basis of the factors which are important for implementation and application of consignment inventory are made. Logistics chain from subcontractor to end customer is becoming more complex when the volume of items constantly increases to satisfy the needs of the market. From that perspective, companies had large inventories but today it is a lot of different solutions to streamline inventory management. One way that recently becomes increasingly common is to let the subcontractor fill up the customers stock using different approaches such as VMI (Vendor Managed Inventory). A further step in the evolution can be to make use of consignment inventory where the vendor owns the stock of the customer.

Dynamisk binär översättning är en teknik för att köra program kompilerade för en plattform på en annan inkompatibel plattform. Tekniken finns bland annat implementerad i många konsolemulatorer, men det finns även andra exempel där tekniken använts, t.ex. vid arkitekturskiften. Nära besläktade områden är dynamisk kompilering och dynamisk optimering. För att undersöka tekniken (dynamisk översättning) närmare implementerades den i en, redan färdig, interpretativ (switch-baserad) Chip-8 emulator.

En mätserie utfördes på en entreprenadmaskin där entreprenadmaskinen var en tandemvält. Data som spelades in på en DAT-bandspelare var motorns rotationsfrekvens, valsarnas vibrationer samt ljudfältet i kabinen. Den insamlade datamängden analyserades m.a.p dess spektra samt ljudnivåer. Vidare predikterades resultat till implementering av det adaptiva systemet ur dessa insamlade data. Viss laboration utfördes på en modell av det adaptiva systemet m.h.a insamlade data.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

This 3d navigation application is a part of a project that helps the user to learn and find the right position on a map with many exercises, the user has a compass nearby that he/she can use to find the position that requires to get the right answer on that particular exercise. Macromedia's Director is used for the creating of the program, where Lingo has a importent part as the script language for the scenes in Director. A 3D scene is build up with codes in Lingo, a few 3d models and serveral overlays are created and displayed on the screen. Different kind of textures from pict files are is representing the overlays and put on the 3D models. That give the user a more pleasant experience when going through the exercises that helpes the user when he/she is going to navigate on a boat at sea..

Although Social Democratic Memoirs comprise an extensive material, these texts have not attracted any systematic analysis as a distinct and yet varied form of textual genre. The focus in this MA-paper is the Swedish Social Democratic Memoir as a rhetoric genre. The main primary material is memoirs of the pioneer August Palm (1849?1922), the father of the nation Tage Erlander (1901?1985) and the political leader Göran Persson (1949?), published 1905, 1972?82 and 2007, respectively.The general aim is to find out what is the driving power of the memoirs and, more specifically, to shed light on the images of the party history and the history of the welfare state. The method is a comparative analysis of these texts.
