Masskattning av tunga fordon i realtid genom systemidentifiering
As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the Mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the Mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..
Grazemore DSS för att prediktera beteskvalitet för mjölkkor :
The aim of this study was to examine if the predictions of the herbage quality in the software Grazemore Decision Support System (DSS) gives a reliable ground for milk production in the north of Scandinavia.
Pasture samples from one research farm (Umeå) and one organic farm (Nordingrå) was analysed on crude protein and organic matter digestibility. The results were statistically compared to the predicted values. Measured and predicted herbage Mass was compared and a control if the predictions of milk production improved if the predicted input were replaced by the values from the analysis, was made.
The concentration of crude protein was underestimated by the model on both farms and the relationship between actual and predicted values was poor. Mean Prediction Error (MPE) was 24% and 31% respectively.
Krafter på rörsystem vid transient flöde : En jämförelse mellan RELAP5 och Fluent
At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.
Svensk massmedias EU-gestaltning Analys av Dagens Nyheters och Expressens EU-artiklar utifrån ett inrikes- och utrikespolitiskt perspektiv
During the time of membership in The European Union Swedish domestic policy has gone through many changes. A lot more political areas are being influenced by the EU policy. Today every ministry has got some sort of EU office. Swedish politicians are functioning on two arenas, domestic and European. At the same time Swedish membership has gone from being highly discussed to being a state of normality.
Anpassning inom dagligvaruhandeln : Fallstudie av Ica Supermarket Torgkassen
Through interaction with customers, companies can acquire knowledge about- and satisfy the needs of customers. In retailing, the ranges of products are standardized and staffing numbers are scarce. How do companies in retailing deal with adaptation towards their customers given the small staffing numbers? The purpose of this study is to examine if and if so, how companies in the Swedish retailing industry are making adaptations towards their customers and also why these adaptations are being made. To answer this purpose, observations in the retailing industry are conducted and the results show that companies adapt to customers? needs.
Lojalitetsskapande genom Mass Customization : Hur skapas kundlojalitet när kunden är chefsdesigner?
Konfektionsbranschen har sedan tidigt 1900-talat fungerat genom ett Massproducerande maskineri som erbjudit ett likriktat utbud till sina kunder, kunder som ansetts vara en enda stor Massa, idag har konsumenter en större insikt i sin egen konsumtion och en stor vilja att påverka. Tack vare den tredje industriella revolutionen är ett nytt paradigmskifte på väg, kunden involveras i design- och produktutvecklingsprocessen och resultatet är att en unik produkt kan produceras samtidigt som företaget uppnår stordriftsfördelar genom modularisering, detta kallas för Mass Customization. Forskning visar att kundinvolvering ofta leder till en lojal kund och utifrån detta är uppsatsens syfte undersöka hur konfektionsföretag inom Mass Customization arbetar med att skapa kundlojalitet. Uppsatsen utgår från en kvalitativ metod där intervjuer med företagen Tailor Store Sweden AB och Suitopia Scandinavia AB är grunden för informationsinsamlingen. Analysarbetet har en teoretisk syntes som utgångspunkt, syntesen bygger på teorier gällande relationsmarknadsföring, kundanpassningar, hur företag skapar lojala kunder samt e-lojalitet.
Massmediekommunikation som strategi för att öka
medlemsaktiviteten inom religiösa samfund
The intension with the thesis is to investigate how Mass communication is adopted as a strategy to increase the membership activity within religious communions in Sweden. In the years past it has shown a decreased activity within religious communion, deliberate strategies have been missing and efforts on resources for less effective strategies have been made. The study has been carried out through a review of existing theory within the field of subject, communication within religious communion and the use of Mass communication within religious communion. The Swedish church was chosen as a case, where three persons were interviewed. The result from this study shows that the Swedish church communication operates on several different levels: these are detached and self-determinate.
Utvärdering av pelletsförgasning för glassmältning : Fullskaleexperiment vid Kosta glasbruk våren 2004
Den negativa miljöpåverkan från förbrukning av fossila bränslen ökar kravet på förnyelsebara energikällor. Biobränsle är ett speciellt lovande alternativ. Detta projekt vill visa på möjligheten att använda gas från biobränsleförgasning som förbränns utan synliga flammor i glassmältugnar. Med bättre teknik är det möjligt både att upprätthålla produktionen och reducera kväveoxidutsläppen med ekonomiska fördelar. Biobränslena bidrar inte till växthuseffekten.
De levandes gåvor och de dödas efterlämningar : -En kemisk analys på harts och ökendadel (Balanites aegyptiaca) från två egyptiska kärl
This paper aims to investigate the embalming process and the Balanites aegyptiaca from two pottery originated in ancient Egypt. The two objects were from Medelhavsmuseet in Stockholm. Samples were collected and analyzed with Fourier transform infrared spectrometry (FTIR) and Gas chromatography/Mass spectrometry to identify which components the samples contained. The results show complex mixtures mainly consisting of resin origin from Pinaceae and the vegetable oils from the Balanites aegyptiaca..
Design av en ejektorspädare samt ett system för partikelmassmätning av dieselavgaser
This master thesis was a subtask of a project called EMIR-1. The goal with the thesis was tobuild a system for particulate Mass measurements in one of the engine test cells at KTH. Theparticulate Mass measurements are planned to be measured with a TEOM.The exhaust gases must first be diluted with air before the sample is sent to the TEOM.Therefore an ejector diluter for this matter also was designed and evaluated in the thesis.Emissions measurements have been done both with and without dilution to determine thedilution ratio. Tests have been done for different speeds and loads.Problems with stability of the dilution ratio have been an issue throughout the process andpressure pulsations in the exhaust pipe are believed to be the cause. More tests have to be done tomake sure that this is the problem.One idea is to make the inner diameter of the diluter nozzle smaller and see if it changes thedilution ratio stability.

It focuses on three areas following the crisis and these are crisis management, recovery strategies and brand management. This study seeks to explain how these areas interact in relation to Massive exposure to Mass media and how they interact restore the brand's potential loss of reputation. This study was conducted as a case study with a deductive and qualitative approach. The data gathered to this study was mainly based on newspaper articles and complemented with semi-structured interviews with twelve local retailers of the brand..
Vuxnas läsning av ungdomslitteratur ? en påse med godis, en trettioårskris eller som vilken litteratur som helst?
I approach the subject of adult readers of young adult fiction through an analytical framework influenced by Cultural Studies, implicating that young adult fiction is caught up in a system of distinction between popular literature and high literature. I contrast this with theories that suggest that there has been a loosening of this hierarchy and that they now coexist, even borrowing features from one another. I also examine questions of ideology, namely the ideology of Mass culture, the ironical attitude and the ideology of populism. I also use Andreas Huyssen?s theory of Mass culture as a woman, seeing as popular literature often tends to be categorized with feminine traits.
Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem Mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Med handen på hjärtat och kniven mot strupen : En kvalitativ undersökning av de svenska bokningsbolagens verklighet
This study focuses on the booking agencies in Sweden and their point of view on the reality with a focal point from the Mass media perspective, which says that they have become rather wealthy because of the changes within the music business. The Mass media describes the booking agencies situation as golden because of the economical and technological changes that more or less have paralysed the record industry. The study is performed with a qualitative approach and is based on interviews with relevant individuals from eight different Swedish booking agencies. These individuals have been chosen to match as many different segments in the booking agency business as possible. On account of the qualitative approach it is difficult to generalize the conclusion of the study.
En gemensam fiende? : -En jämförande studie om olika staters syn på terrorism
Even though terrorism has been on the political agenda for several years there is no general accepted definition of the phenomena of terrorism. Several scientist do also apply that terrorism have changed after the 9/11-attacks. The purpose with this thesis was to analyze and compare the image of terrorism represented by the United States, United Kingdom, Sweden and Norway, in an attempt to draw conclusions about similarities and differentials. The material that was used was these four nations individual counter terrorism strategy. This was made by using idea analysis and self constructed dimensions based on earlier science about security, terrorism and international law.
