This thesis presents the implementation of a knowledge base system for rough sets [Paw92]within the logic programming framework. The combination of rough set theory with logic programming is a novel approach. The presented implementation serves as a prototype system for the ideas presented in [VDM03a, VDM03b]. The system is available at "http://www.ida.liu.se/rkbs". The presented language for describing knowledge in the rough knowledge base caters for implicit definition of rough sets by combining different regions (e.g.

There has been an increase in the importance and amount of information concerning publicly traded stocks in recent years. When analyzing and valuing stocks finding new ways of collecting information has therefore increased in importance. This thesis aims to explore how meetings with management can impact the stock valuation done by the security analysts. Furthermore the case study examines what kind of information analysts can receive by interpreting management at these meetings. This case study of ten Swedish security analysts show that the analyst?s stock valuation is directly or indirectly affected by the meetings.

Vad många inte tänker på då de har ett relativt avancerat olinjärt system som de linjäriserat till ett tidskontinuerligt styckvis affint system är att det inte är helt självklart och enkelt att hantera detta system. Eftersom vi i de flesta fall vill kunna hantera ett angivet system med datorkraft, och därmed måste sampla systemet, behöver vi kunna beskriva ett samplat tidskontinuerligt styckvis affint system med ett tidsdiskret system. Vid första anblicken av detta problem kan det verka ganska enkelt. Vad många gör är helt enkelt att skapa en tidsdiskret beskrivning för varje mod i det styckvis affina systemet var för sig och behålla de gamla modgränserna. Detta visar sig dock kunna ge ett felaktigt uppförande hos systemet.

AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined  how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.

Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.

The purpose of this essay was to analyze the management and steering of the social welfare service. The objective was specifically to examine how the leaders approach their position as managers of the social welfare service, and also how they approach their way of steering. The social welfare service acts under political decisions, but the management interpret and transform these decisions into actions. The managers of the social welfare service are therefore important from a democratic perspective. The study was based on five qualitative interviews with two managers of the unity, two departmental managers and the head manager of the social welfare service.

Swedish school has for the last decades been using quality management as a method for improvement. Quality management is an enormous work and the whole school staff needs to be involved. The management consists of several parts like planning, surveys and interviews, analysis of the replies and setting up new goals. Parents, children and teachers are nowadays accustomed with quality surveys. The last few years these quality surveys have been computerized, but they still look almost the same, using little interaction with the respondent.I have had the opportunity to work with the company KMF Ventures, which has a vision that entails a more interactive web survey.

Den traditionella ekonomistyrningen har kritiserats för att ge ett bristfälligt beslutsunderlag med schablonmässiga kostnadsfördelningar. ?Activity Based Costing? - ABC har lösningen som åtgärdar bristerna med en alltför aggregerad information. Stark kritik har även riktats mot de finansiella nyckeltalens särställning och alltfler företag har därför börjat komplettera den finansiella redovisningen med nyckeltal som grundas på andra än rent ekonomiska värden. De immateriella tillgångarnas betydelse har i allt större grad accepterats.

A new system of public transportation that can simplify and shorten the trips made throughout the city, anddo that both cheap and environment-friendly. Sounds like good news. This new system, though, require anall new type of infrastructure, differing from what we are used to see in our cities. Podcar, or PRT, as thesystem is called can become a transport revolution, possibly. If that revolution does happen it is crucial that webeforehand have studied the possible effects it can cause on our city environment, from a spatial point of view.This thesis thoroughly describes the function and essence of the PRT system and presents what is availabletoday and in what forms.

Integration av system har varit ett aktuellt område under de senaste åren. Det har då främst handlat om integration av system internt på företag. En av anledningarna till det stora intresset av web services är möjligheterna att integrera olika system, exempelvis stordatorbaserade och Windowesbaserade system med varandra. Web services handlar om att kunna integrera system, både internt på ett företag och externa mellan olika företags olika typer av system. Allt detta görs via Internet och bygger på att man utgår i från standards när man bygger web services.

ABSTRACT Introduction: During the past 40 years the ambulance service in Sweden has evolved from mainly being a source of transport to today?s high-tech caring facilities that enable qualified care to start already in the patient?s home. This first level of care is now provided by registered nurses and registered nurses with specialist training in pre hospital care.At the same time as the care provided is becoming more advanced, results from studies demonstrate that the amount of dispatches to patients that lack the need for ambulance care and transport is increasing. Nurses in pre-hospital care possess the knowledge, training and authority to perform an initial assessment of patients and also treat patients according to local and national guidelines. After the treatment it would sometimes be possible for the patients to remain at home without having to use ambulance transport to an emergency department or in other cases find other means of transport to hospital.

This final thesis consists of an investigation of how suitable it is to vertically integrate forest in Swedish forest companies. Different strategies to obtain raw materials have been evaluated and the advantages and disadvantages have been weighted against each other. The investigations contain a number of interviews with represents from companies with different strategies and persons that in different ways have faced the question of issue. An account study of SCA´s forest ownership has also been performed. The benefits for a forest company to vertical integrate forest consist mainly of safety in delivery, control over the supply chain and company image.
