Upprättande av kvalitetsmanual enligt ISO 9001:2008

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik

This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

Metallersättning inom byggbranschen

In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

Möjligtvis stressad? En kvalitativ studie om stress på ekonomiskt bistånd, en enhet på Socialtjänsten

The purpose of this study was to examine and illustrate whether employed social workers, working with supplementary benefits at a social service office, felt stressed. If so was the case, we wanted to investigate if this stress that they felt had any effect on their clients. This study was based on eight qualitative interviews, of which four was with social workers and four was with clients. For a better understanding of our results we used Karasek & Theorells demand-control-support model.The study reveals that the social workers do feel stressed, but they only do so in periods. They declare that they would like to have more time for their work assignments, the meetings with the clients in particulate.

Skönlitteratur på skärm: En explorativ undersökning om e-boken och dess konsekvenser för litteratursamhället

This thesis should be regarded as an integrated research synthesis. The purpose has been to analyse how the literary sociologist Lars Furulands model the literary process correlates in relation to todays book market for fiction. The central problem has been: In what different ways can some of the main actors featuring in Furulands model of the literary process use, produce or provide copyright protected works of fiction which are electronically distributed? Three questions have been considered to penetrate this problem: In what different ways can to judge from some projects which have been carried through at common public libraries electronic works of fiction be provided to their presumed readers? What reasons could there be as it appears in a number of texts that four Swedish authors have chosen to disseminate their works of fiction by the aid of the Internet? Which main functions may, according to current research, be supported by electronic media in connection with editing and retail of fiction? During this study a picture of two quite disconnected processes of publication has materialized. These processes seem to proceed parallelly to each other, without any close contact, in a traditional respectively an electronic circuit.

ADHD som meningsskapande diskurs : om ADHD i socialt arbete i kriminalvården

The aim of this study is to discuss the diagnosis ADHD as a meaning-making discourse that is something more than just a diagnosis with a set of symptoms. I aim to discuss that the diagnosis is productive and can be seen as a means to control and to comfort individuals. The research was based on a method consisting of an idea analysis and a discourse analysis. I am using both a discourse analysis and a critical ideology analysis as perspectives. These perspectives are also based on a general theory of late modernity.

Styr uppfattningen om dig själv  : En studie i hur chefredaktörer för modemagasin arbetar med sina personliga varumäkesidentiteter

The theory chapter is based on a model about brand identity, ?Brand Identity Prism? (Kapferer, 2008, s.183). This model contains six elements which we have supplemented with theories about personal branding. This because the focus and theory on a person's brand identity is almost non-existent. The purpose of the study is therefore to examine how editors at fashion magazines are working with their brand identity in the personal brand and thereby create an understanding of the identity function.

Numerisk modell för global transport av spårämnen i atmosfären

The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this characteristic, the Courant, Friedrich and Lewy-condition for numerical stability puts a sharp bound on the timestep length.

Prediktering av fartygsbränsleförbrukning i varierandesjötillstånd

  During the 2000s, the ship owners have become more and more concerned thattheir ships save fuel. Several projects have been undertaken to exploit the resourcesavailable on board today?s vessels to reduce fuel consumption. As a stepin this the Swedish Meteorological and Hydrological Institute (SMHI) today offera Weather Routing service to ships. By planning your route more effectivelymuch fuel can be saved.This thesis has been about developing a fuel prediction program (FPP) forhow much fuel a ship consumes in different sea conditions.

Fashionably fit for the future? ? A demonstrative study unravelling the concept of scenario planning

Purpose: The purpose of this thesis is to clarify and evaluate the concept of scenario planning.Methodology: Our research methodology has a qualitative approach and uses deductive reasoning. The theoretical field of strategy formulation has been reviewed and in specific the concept scenario planning was unravelled and mapped. Thereafter, our model was tested in a case study where the empirical data was collected through personal interviews. Theoretical field: Literature and articles from the strategic management field have been reviewed with a focus on strategy formulation, scenario planning and Williamson?s theory for the creation of a portfolio for strategic options.Empirical base: Personal interviews and secondary sources such as financial reports, articles mainly from industry media and articles found in the databases ELIN and Affärsdata.Analysis: The analysis work constitutes the testing of our model for scenario planning, integrated into Williamson?s portfolio of strategic options for the future.Result: The work has resulted in a clarified model of scenario planning with links to strategic management schools.
