Test av modeller för prioritering av förändringsförslag i Stora Enso Skog AB´s nya produktionsplaneringssystem VSOP

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

Effektiv provningsmetodik för växelföringsdamasker

Completed durability testing of gearshift gaiters at Kongsberg Automotive in Mullsjö, is sometimes leading to discussions regarding whether or not a gaiter is supposed to be a pass or a fail. That is because the current pass/fail-criterion are a bit vague. A durability test takes around 4-5 weeks to complete which is a long time if the tested material does not pass the test and a new material has to be tested instead. Stricter pass/fail-criterions and a faster testing method for the materials are therefore desired.In order to develop a durable pass/fail criteria, seven already judged gaiters were chosen. Every one of the gaiters was put through detailed analysis, after which there were a new assessment of the gaiters.

Varför stannar soldater i Försvarsmakten? : En studie på 72:a kompaniet

The study was conducted on 72nd company at Livgardet in order to find out what motivators makes the soldiers stay. The material in the essay is based on an interview with soldiers from the 72nd company. The motivators are then categorized in the model Employee Motivation: A Powerful New Model. The model is based on human drives and I used as a tool for the analysis to identify lack of motivation in a working place. The study shows that the key motivators that make soldiers stay is: the opportunity to go on a peacekeeping mission and comrade/esprit de corps, the soldiers state that they will quit without these two essential motivators.

Mekanisk modell av människans huvud för simulering av skalltrauma och hjärnskada

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Kulturprojektets karaktär : Perspektiv på ett lyckat resultat

Projects is the most common work model within the cultural area, but what is a cultural project? The definition of cultural projects is ambiguous. There are also no compiled information about what it means for culture to be pursued in project form. Scientific research about traditional project management and success criterias are wide-ranging. So is the scientific research about cultural studies and cultural policy.

Den personliga konflikten

The purpose of this study was to examine the relation between the Big Five personality traits Extraversion, Agreeableness and Neuroticism and the five conflict styles developed by Thomas-Kilmann: Accommodating, Avoiding, Compromising, Collaborating and Competing. The participants consisted of 128 students of the Linnaeus University in Växjö. A questionnaire consisting of two parts were used for this study: Part one consist of a personality-test developed from Lewis R. Goldberg?s Big-five scale, and part two where the participant is asked to fill out Thomas-Kilmanns conflict style test.

Den korta armen : En studie i mångfald och armlängdsavstånd i kultursamverkansmodellen

The name of the study means ?The short arm - a study in diversity and arm?s length in the cultural collaboration model?. Right now there is a reform in the Swedish cultural administration where the responsibility for handing out state funds and grants to cultural organizations is changing from the state government to the local regional governments. The purpose of this study is to map the organisational changes caused by the reform and investigate how this affects the regional policies concerning cultural diversity and the arm?s length principle.

Modeller för studier av ursprungsmärkt el

The EU has decided that it should be possible for consumers to get information about the origin of the electricity they buy. Therefore, there is a need to examine different systems for electricity disclosure. In this thesis two ways of disclosure have been studied:? Certificate system. A certificate system involves two parallel markets, one for trading electrical energy and one for trading certificates of origin.? Separated Markets.

Trefaktorsmodellen : Undersökning på svenska börsnoterade aktiebolag

Previous work by researchers as Eugene F. Fama and Kenneth R. French, show that average return on stocks are related to a firms characteristics like size and book-to-market ratio. These kinds of patterns in average return is not explained by The Capital Asset Pricing Model (CAPM), and are therefore seen as anomalies. Fama and French have proposed a three-factor model, which captures patterns observed in U.S average returns associated with size and value.

Hassel (Corylus avellana) som indikator på markanvändningshistorik

Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

Den demokratiska konsolideringen i delade samhällen - fallet Makedonien En studie om Makedoniens demokratiska utveckling efter den väpnade konflikten år 2001

The consociational democracy model in Macedonia, which came out from a warcrisis and a peace agreement from 2001, in addition, putting an end to the violent conflict, actually admits the division of the society along the ethnic lines. Paradoxically, there is an attempt to bridge the ethnic gap with this model. As a result, the consociational democracy model holds solutions that can be abused if somebody misuses its power and desires to disintegrate the country. The future development depends therefore on the moderate attitude of the citizens, and first and foremost, on the political elites and their commitment to the values of democracy and human rights instead of their nationalistic goals. Furthermore, thepresent democratic consolidation in Macedonia is established on the execution of the peace agreement and the improved effectiveness of the institutions.

Modellbaserad ekoföljning i vätskefyllda tankar

This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

3D-modellering i AutoCAD -att skapa en digital huskonstruktion

3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.

Rocchio, Ide, Okapi och BIM : En komparativ studie av fyra metoder för relevance feedback

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

Termomekanisk utmattning av Sanicro 25 : Materialmodellering med finita elementmetoden

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.
