Vid införandet av säten är det viktigt att ta hänsyn till passagerarintensiteten, det vill säga hur tätt sätena ligger. Den kritiska mätvariabeln står för avståndet mellan en punkt på ett säte och samma punkt på nästa säte. Mätvariabler som har små värden, det vill säga korta avstånd betyder fler rader och därmed högre vinst. Överblivet utrymme är ett dyrt slöseri då skillnad mellan vinst och förlust för en viss flygning kan vara så liten som mindre än en kostnad för ett säte.Syftet med detta arbete är att ta fram en matematisk modell som hittar den optimala sätesfördelningen mellan klasserna i ett flygplan. Den modell som skall ställas upp ska maximera intäkterna och ytanvändningen för ett flygbolag samt möta efterfrågan.

This Bachelor Thesis in the area of Computer Science and Work Science describes the process of design and development of an IT-tool between the municipality of Ron-neby and TietoEnator a development and consultancy firm, the Gothenburg office. The thesis focuses mainly on the cooperation between the consultant designer and the local municipal. Through cooperation, the organisation is incorporated into the tool and the tool is incorporated into the organisation. Concepts that are central in this thesis are design, cooperation and tailoring. A question raised is, if distance work and extensive cooperation might be a good way of working in the process of design and development, when the organisation is being incorporated into the tool. Advan-tages and disadvantages of this way of working are discussed. Our studies show that distance work is a good complement for personal meet-ings between designer and co-developer.

IASB is currently working with the replacement of IAS 39 Financial Instruments: Recognition and Measurement. The new standard IFRS 9 Financial Instruments is said to be based on principles as opposed to the more rules-based IAS 39. This thesis examines the third phase of the project regarding micro hedge accounting. The expressed goal from IASB is to provide more useful hedge accounting information by reducing complexity of the standard. To examine the potential effects of the transition from the rules based IAS 39 to the more principles based IFRS 9, we have performed a case study on a major Swedish bank.

In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.

Bakgrund: Detaljhandeln har under de senare decennierna genomgått en förändring där större kedjor tar allt mer plats. Den levande debatten om vikten av småföretagandet i Sverige gör att frågan väcks om vad som händer med småföretagen i detaljhandelns utveckling. Samverkan kan vara ett sätt för småföretagen att konkurrera mot de större aktörerna. Småföretagaren beskrivs inte sällan ha en önskan om att arbeta självständigt och en stark vilja om hur det egna företaget ska drivas. Då två av tre småföretag ändå väljer att regelbundet samarbeta med andra företag är det av intresse att undersöka vad småföretagen har för motiv till samverkan.Syfte: Syftet med denna studie är att undersöka varför småföretag väljer att ingå organiserad samverkan.

Idag ses information om tvärsektionens geometri under vattenytan som vital för att kunna utföra översvämningskarteringar. Att ta fram sådan information kan dock många gånger vara en både tids- och resurskrävande process, varför det är intressant att undersöka möjligheterna av att förenkla denna del av översvämningskarteringen. Med Väsbyån som studieområde syftade denna studie därför till att undersöka hur viktig tvärsektionens geometri under vattenytan är, i förhållande till Mannings tal, för möjligheten att förutspå vattenstånd vid större flöden än normalflödet. Detta gjordes genom att i modelleringsprogrammet HEC-RAS skapa två fiktiva tvärsektionsformer, en rektangulär och en triangulär, vars dimensioner anpassades efter ett känt flöde och vattenstånd. Därefter simulerades olika extremflöden för de två olika tvärsektionsformerna vid olika Mannings tal.

Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.

To challenge the competition within the construction business there are requirements ineffectiveness and use of operating computer based programs and work-methods. Thecomputer based programs are continuously improved and can at some point be the start of anew work-method. The work-method of tomorrow can be Building Information Modeling(BIM).This Master of Science Thesis gives an understanding in what BIM is and what therequirements for Sweco Theorells are in a future BIM-use as a consulting-firm. Theunderstanding is presented through a study of theory within the subject. The way of thinkingand acting among different disciplines and individuals within the building process isexplained through an interview study.The term BIM is regularly used.

Internationalisering har länge ansetts vara positivt och bra för företags ekonomiska tillväxt och globala konkurrenskraft. Det finns dock både fördelar och nackdelar, vilka varierar beroende på företagets internationaliseringsprocess, det vill säga på vilket sätt och till vilken grad företaget internationaliseras. En mängd forskare inom internationell affärsverksamhet har tidigare studerat sambandet mellan internationaliseringsgrad och finansiell prestation. Resultaten har dock varit varierande, men många av de senare forskningsresultaten tyder på att ett icke-linjärt samband existerar. Inga likande studier har gjorts på svenska företag vilket denna studie ämnar göra.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

The contact company, LRF Konsult, is a consulting firm specialized in areas of law, real estate, finance and taxation. Discussions on the subject of agricultural improvement in the area of Lean, has primarily been driven by the Royal Swedish Academy of Agriculture and Forestry, where LRF Konsult also participated. This thesis can be seen as a preliminary study of how Lean can work within agricultural enterprises.The thesis primarily focuses on the possibilities dairy farms have to improve operations. What practical benefits they can obtain through the implementation of Lean. And how an implementation could take place.By visits to two dairy companies, and through interviewing their respective business leaders, an image of the companies activity for improvement, in connection to this thesis was established.

Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.

AbstractProblem: This thesis was made by a commission from Svensk Logistikanalys AB (SLA). SLA is a relatively new firm who is working as a freight broker for firms that wants to lower their freight costs. SLA contacted Jönköpings international business school because they experienced a problem with too many firms, that had SLA?s concept introduced to them, but turned down their services. On the basis of this, following purpose of the report has been stated.Purpose: In this thesis we will study companies that have said no to the services of SLA.

The purpose of this study is to identify the points-of-difference that should form the basis for Bryggarsalen?s future marketing efforts. Bryggarsalen is a newly established conference business in Stockholm. To be able to identify these points-of-difference, Bryggarsalen?s marketing problems have been studied from the resource-based view, claiming that the source of sustained competitive advantage derive from a firm?s unique bundle of resources.

Mekaniska system har länge varit av intresse för vetenskapenoch vår förmåga att matematiskt beskriva dess dynamikär mycket god. Att effektivt kunna härleda de nödvändigaekvationerna är dock inte trivialt och uttryckensom bildas är ofta icke-linjära differentialekvationer som ejleder till explicita lägesbeskrivningar av de rörliga komponenterna.Idag finns kraftfulla matematiska metoder ochdatorverktyg som möjliggör simulering av relativt komplicerademekaniska system vilket denna rapport ägnats åtatt undersöka med hjälp av exempelsystem. Två utvaldamekaniska systems beteenden med varierande begynnelsevillkorhar undersökts med hjälp av datorsimuleringar. Detförsta systemet har bestått av två pendlar med en fjäderfastspänd mellan pendeländarna. Det andra systemet harbestått av en fritt rullande cylinder på horisontellt underlagmed två pendlar fastspända på änden.
