Vektorkvantisering för kodning och brusreducering
This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..
Utveckling av 22 : -en motkolvs HCCI motor
Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.
Jämförande tidsstudie vid riskörning med kompakteringsskotare och traditionell ?lätt? modifierad skotare :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU.
The work was an assignment from Sydved Energy AB. The aim of the work was to compare the operational productivity between two kinds of forwarders for extraction of harvesting residues, one forwarder with a special compression device and one ordinary, slightly modified forwarder.
Two sites were studied for each forwarder. The study shows that the annual production was about 11,000 m3 higher for the traditional forwarder. The cost for the traditional forwarder was SEK 0.9 lower per m3.
Implementering av realtidsvideolänk med MPEG- och wavelet-teknik
At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.
MÖJLIGHETERNA MED CLUSTERED COLUMNSTORE INDEXES & IN-MEMORY OLTP
Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.
Varumärken- att betrakta som symboler för produkter eller image?
Uppsatsen behandlar problematiken om när ett varumärke ses som en symbol för produkten eller för en image, t.ex. en livsstil. Berör ett företags mission och vision, symboler och tecken, varumärkets image och konsumentens image samt produktens och varumärkets livscyklar..
Uppfattningar om tryckved bland träbearbetande företag i Sverige :
The primary purpose of this study has been to investigate the Swedish timber industry?s
perception of compression wood. A secondary aim has been to describe particular areas
within the production process where compression wood is likely to cause problems.
This study has mainly been carried out as a questionnaire. In order to connect the findings to current research, additional information has also been collected by means of a literature review. The questionnaire has been intended for sawmills and wood-manufacturing companies from various production classes and owner categories, as well as from different parts of the country.
Vidareutveckling av sport-bh för större byst
I denna studie behandlas vidareutvecklingen en sport-bh för kvinnor med stor byst. Forskning inom relaterade områden, såsom begreppen ?encapsulation? och ?compression?, studier av bröstens rörelsemönster under fysisk aktivitet, storlekssystem och bröstens anatomiska förutsättningar, har studerats för att ytterligare hjälpa utvecklingen av denna produkt. En mindre enkät utfördes bland vanliga, på olika sätt, fysiskt aktiva, kvinnor för att avgöra vilka preferenser dessa hade gällande sport-bh. Denna information har sedan tillämpats, i möjlig mån, på produktutvecklingen.
Folkbiblioteks image på Facebook : Undersökning av fyra folkbiblioteks imageskapande och mottagande på Facebook
This essay was to investigate what self-image public libraries convey on Facebook and what image is received by the users, along with comparison of those. It was investigated if the received image corresponded with the users? previous image of public libraries. The method used was interviews with the Facebook administrators and surveys with the users. The theoretical framework was Kotler?s model for image creation.The research is mainly American and shows Facebook as an accepted marketing tool for libraries among students, but as not taken seriously by the library staff.
Bildförbättring över en bildsekvens
When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
Automatisk segmentering och maskering av implantat i mammografibilder
A report on my thesis developing an algorithm to automatically classify a mammogram image as containing an implant or not and segmenting and masking any present breast implant in the image..
Image follows structure
Background: The business market today is characterized by tough competition amongst the competitors to capture consumers? interest and money. One marketing tool companies can use to achieve this is the company?s image. The customer buys not only a product, but also the image that the company or the product is associated with.
Varumärkesimage ? utanför företagets kontroll
Companies spend huge amounts on communicating their brand through marketing. Many of these contact areas where the consumer comes in contact with the brand is con-trolled by the company. The brand image is also affected from outside the company. It can be from users, media, blogs etc.Burberry is an example of a company that got in trouble with their brand image after hooligans where associated with their products. If a company with a brand with a strong image is associated whith consumers that are not compatible with the target group the company wants, there is a risk of a negative affect on the brand image.Our purpose is to investigate and describe the phenomenom when a company brandimage is affected by being associated whith consumers not compatable whith, by the company, intended target group.We have chosen a qualitative research where we use a multiple case study.

Body image is a term that refers to a person?s feelings and attitudes toward his or her body. There are many different factors that influence a person?s body image: historical, cultural, social, biological and individual. The purpose of this study was to investigate young Indian women?s body image in India from a cultural perspective.
Samspel mellan Identitet och Image : En fallstudie av det Svenska fo?retaget POC
Purpose: The purpose of this paper is to examine if POC manage to keep cohort interplay between their identity and image.Theoretical framework: This paper is led from theories in area about communicating identity and image. The theories that are relevant to this paper to see the interplay between identity and image is communication theory and brand theories based on associations. From these theories we have composed a model that shows the communication led from identity throughout image in company?s with many distribution channels. It shows what associations that build identity and image and also the complication and threat that the interplay is being exposed to.Methodology: We have chosen to do this examination as a case study.
