This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.

This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.

Man?s impact on the environment is something that increasingly becomes topical in today?s society. Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.

IT is a natural part of the work today when it comes to projects. There are many aspects that are wholly or partly dependent on IT support actions to proceed efficiently. Although there is still situations where IT is deselected as a tool. The factors that make it look like this is not always included in the calculation, which resulted in the failure that could have been remedied with the right tools to solve the problems. The project form which today is increasingly common with all major groups involved enables IT tools' impact also becomes an increasingly provided they are used properly.

AbstractTitle: Environmental demand solutions - a study within real-estate business.Problem statement:Today, the society stands before a permanent accelerated environmental threat. Companiesbecome increasingly over the environmental problems and more companies look over theiractivity and how it influences the environment. Historical the environmental issue has been forgotten and it is first during the end of 1990 the environmental issue intensive has been noticed. Earlier the environmental work?s high costs was the cause, but now the companies realized the weight and the importance of imposing focus on environment commitments and sees it, as an investment.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

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.

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Inledning: Såväl politiker, som media och många andra kritiserar undervisningen av svenska för invandrare (SFI) kraftigt, det diskuteras att invandrarna inte lär sig svenska i önskvärd omfattning och integrationen av de nyinkomna går dåligt. Studien har därför velat undersöka dessa frågor SFI-deltagarnas syn på andraspråksinlärning och deras integration.Syfte: Studien avser att undersöka vad SFI-deltagare anser om SFI:s medverkan till integration och andraspråksinlärning i det svenska samhället.Forskningsfrågor: 1. Vilka diskurser framträder i SFI-deltagarnas konstruktioner av vi och de andra?2. Vad är SFI-deltagarnas syn på SFI:s medverkan till deras integration i samhället?3. Hur har SFI konkret bidragit till SFI-deltagarnas integration, avseende t ex arbete, vänner, kontakter, studieframgång, boende och skola?Metod: Diskursanalys enligt diskurspsykologisk metod.Teori: Den här studien har sin teoretiska förankring i socialkonstruktionism med influenser av postkolonial teori och kritisk teori.Resultat: Antagandet var att bristande språkkunskaper skapar segregation och omvänt, vilket besannades. Sammanfattningsvis kan sägas att informanterna uttryckte en massiv kritik av SFI:s förmåga att hjälpa dem med integrationen och att de även var kritiska mot praktik och arbete och mot den språkträning som de då fick. Men de är inte enbart kritiska till SFI-undervisningen, de ser även positiva effekter av undervisningen.

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

The interactive whiteboard (IWB) is to be found in many classrooms in Sweden, and its number is growing rapidly. There is a lack of research of the use of the IWB in Sweden. The Swedish National Agency for Education refers to English research where the investment in the IWB in school is huge. In this study I will investigate how the IWB can be used as a mediating tool in the learning process. My study examines how interaction pattern appears when the teacher teaches with the IWB as a tool.

Sweden has distinct seasons with cold winter and temperatures down to minus 25 ?C andpleasant summers with temperatures above 20 ?C. During spring and autumn there could becomechallenges with precipitation. The diverse climate in Sweden affects many homeowners. For thepeople living in leisure boats and permanent housing boats the seasonal changes are clearlyimpacting their economy and the indoor climate.

Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.

Due to historically low prices for electricity in Sweden, many small-scale hydropowerplants were closed down. A small-scale power plant has more or less the samemaintenance costs as larger plants, but doesn?t generate as much income. Today?sincreasing price for electricity in combination with a desire for renewable energysources makes small-scale hydropower interesting again.

Abstract: Since the recession caught the market in fall 2008, multiple companies have suffered due to their former aggressive investment behavior. Huge goodwill piles have been collected ready to be doomed by the market. The aim of the study is to investigate equity analysts? consideration of goodwill in a recession market. An empirical study is conducted, based on interviews with ten Swedish equity analysts that follow companies with relevant goodwill status.
