Effektiv lagerstyrning genom tillförlitlig prognostisering : Effective inventory control through reliable forecasting

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

En andra chans ? en överblick av secondhandkläders marknad

In our globalized society massconsumption is widespread. However there is a trend showingthat people are starting to re-use clothes instead of buying newly produced garments. Reasonsfor buying secondhand clothing are many. During the 1950s people strived to look likeeveryone else but in the 1960s this changed. Subcultures grew stronger.

Besparingsmodell för produktivitetshöjande arbete inom skärande bearbetningsteknik

The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.

Att beskriva etnografiska föremål med hjälp av ämnesanalys och ämnesindexering

The aim of this masters thesis is to analyze how subjects of ethnographical objects should be described. To obtain this we focus on which subject aspects of ethnographical objects that could be possible and valuable to analyze and to index. This is done with the help of established LIS subject indexing theories, and through the perspective of ethnographical museum documentation. The theories are both general, concerning the stages of subject indexing, and more specific, regarding the indexing of pictures. One of the latter is the theoretical model of Sara Shatford, from the article Analyzing the Subject of a Picture.

Nitrat i grundvattnet : Modellanalys av vattenflöde till Hörviks vattentäkt

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Den litterära nätsajten Vulkan.se och en ny modell för den litterära processen

The aim of this thesis is to investigate how the literary site Vulkan.se affects the conditions for publishing, distribution, incorporation in value systems and feedback in the literary process, as it appears in Lars Furuland?s model of this process. The purpose is also to propose an updated version of the model. This is achieved through a qualitative testing of Furuland?s theory.

New Business Model for District Heating Firms Stabilizing the National Energy System with a Future Variable Electricity Production

The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.

Talent Management. En studie av det praktiska arbetet med Talent Management i fem företag

Globalization and demographic changes are forcing today?s companies to be more competitive in order to reach success. The increasing competition is proving a challenge for companies to recruit and retain competent, talented staff. To meet these challenges, Talent Management was developed during the 1990s and supplies a new and innovative way to deal with personnel management. Due to Talent Management being a relatively new theory, there is at present no generally accepted definition of the theory.

Smålands Musikarkiv: att samla och förmedla

This study examines the cultural factors which necessitated the establishment of The Music Archives of Småland in 1991 in the city of Växjö. I wanted to know the importance of the local music tradition and the role of those people who worked to create an institution such as this. In order to do this I interviewed the chief collector of early folk music, Magnus Gustafsson, and made use of literary sources to devise questions and evaluate the results of the exercise. In this study I have made use of a model of a musical culture in a society, created by Lundberg and Ternhag, based on the theory of cultural fields by Pierre Bourdieu. According to this model, the stature of a musical culture gives different forms of musical expression certain roles, but these roles can be remodelled, reflecting perhaps political or ideological influence.

FEM?modeller för expansionsanalys av piplines

REINERTSEN AS performs expansion and buckling analyses of pipelines using ANSYS, afinite element modelling and analysis tool. In an expansion analysis the pipeline is modelledwith thin?walled pipe elements called PIPE20 which allows plastic deformation. However, ina recent analysis the results retrieved from the PIPE20 element were incorrect for strainsabout 1 percent. One main issue was that the PIPE20 element overestimated the strains.The purpose with this Master Thesis was to become familiar with the theories and analysismethods used in pipeline design.

BIM i planeringsarbetet : Effective planning by using BIM

AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.

Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB

The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Hållbar Ö ? en analys av möjligheterna att försörja ett modellösamhälle i Stilla Havet med solel

The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.
