The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting timber. The method was tested in a case study at a district. The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.

TitleFactors for success : a study of school libraries at compulsory schools and how to integrate them in the educationAbstractThis Master's thesis aims to identify success factors for the integration of school libraries in the education. The search for factors are concentrated to three areas: control documents for the school and school library, the Principal and organisation and the collaboration of librarians and teachers.The method consists of three parts: a documetary study, a questionnaire survey and interviews. The documentary study aimed to reveal how concrete control documents for schools and school libraries are concerning pupils' information literacy and school libraries. The questionnaire survey gave a general view of the situation of school libraries in Skåne and to help identify two suitable objects for closer examination. Gunnesboskolan and Rönnowskolan were chosen, and the principals, the school librarians and teachers representing different subjects were interviewed.Our results indicate that there are important factors in all three areas examined.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

This report will outline a proposal for the improvement of the baggage sorting facility at Arlanda airport. Swedavia is a state owned company group that operates, owns and develops airports in Sweden. One of their main roles is to create accessibility needed to facilitate and streamline the work at the airport.Swedavia is constantly working to develop new solutions and enhancements that will help to standardize and automate the work at airports without major impact on climate and above all adapt these solutions to work.The project has been aimed to identify and isolate the problem at the check-in counter, investigate the possibility of setting a speed control on the DC motor driving the luggage conveyer belt at the check-in desk so that the luggage does not lose tracking already there, as well as evaluate the new sorting systems planned to be introduce in the upcoming refurbishment of the sorting area.To determine the parameters that are used to regulate the speed of the baggage conveyor belt, information about the inputs and outputs that participated in the process was gathered. Information was collected both practically and theoretically. Process was followed and monitored by the supervisor of the company, and a theoretical study was done separately on my own.

I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.

Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Syftet med studien är att undersöka huruvida interna och externa variabler påverkar personers friskhet samt utreda hur långtidsfriska skiljer sig från övriga medarbetare. Undersökningen genomfördes med ett frågeformulär bland personal med olika arbetsuppgifter. 150 medarbetare besvarade enkäten. De undersökningsvariabler som ingår i den interna skalan är personlighetsdrag, locus of control, KASAM och optimism. Den externa skalan består av krav, kontroll, stöd, ledarskap samt organisationskultur.

This paper describes a case study of the largest film production ever conducted in Scandinavia. The study aims at explaining the complex relationships in the network structure in which the project took place. Coordination of creative projects carried out in a network context, includes handling conflicting interest and contradictions. Creativity needs space and freedom while projects need structure and coordination, whereby controlling these projects becomes complex. Adding to the complexity, does the loose form of organization that the network structure represents, without any long term structure.

The term maneuver warfare is frequently used in western defense doctrines and theoreticaltextbooks. The ambition of the Swedish armed forces is to attempt maneuver warfare in allappropriate situations. Theories and doctrines indicate the importance of decentralized command and control systems. Mission command (Auftragstaktik) is one such system and should be applied to all situations of the Swedish Armed Forces. There are theoretical and doctrinal bases for warfare and command, but in practice, what are the preconditions for this? Previous research addresses many theoretical questions but there are flaws in existing studies investigating practical realities.The purpose of this study has been to reach a deeper understanding of armed forces ability to maneuver warfare by analyzing conformity of command and leadership perspectives in practice.This is an interview-based qualitative case study in which respondent´s statements were analyzed and interpreted in relation to a theoretical framework.

Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf. To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.

The purpose of this master thesis is to map and analyze the appropriate valuation approaches used for Intellectual Property rights and develope a model for valuing patents. This project has been executed on behalf of Electrolux?s Group Intellectual Property and is intended to be used for managerial purposes.Project limitations include patents that doesent concern technology oriented products and services, real option methods, financial forecasts, decisions concerning patents taken by the R&D division, patent applications in general and taking into account unexpected future management decisions regarding patents.Electrolux?s Intellextual Property team applies, manages and protects the groups Intellectual Property rights including patents, designs and trademarks. With an increased globalization and the rise of emerging markets, incentives have increased further to protect and safeguard the group?s innovations.Mainly there are three different valuations approaches for valuing intellectual property rights, these include the income based approach, cost base approach and market based approach.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.
