I then present examples of sound documentation concerning theconservation of built environment. In addition, I have interviewed five key informants who all have a centralresponsibility for five cultural heritage environments.

Analysis of Intent Specification and SystemUpgrade Traceability

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

Sådd av tallfrön med vattenryggsäck : en laboratoriestudie

Föryngring av skog är en nödvändig, men kostsam åtgärd och därför är det eftersträvansvärt att hitta en föryngringsmetod som är både kostnadseffektiv och ger en bra föryngring. Ett sätt att få en billigare föryngringsåtgärd är att använda frösådd. Vid en lyckad sådd gör det stora plantuppslaget att plantorna får bra förutsättningar för god kvalitet. Dessa plantor får dessutom bättre rotutveckling och stabilitet än planterade plantor. Användningen av skogssådd är dock begränsad av bl.a.

Valresultat och börskurser : En eventstudie om riksdagsvalens effekter på Stockholmsbörsen

Background:It is always fascinating to observe the events that affect the stock market, especially as the numbers of influencing factors are so many and various. Political elections are important events in society and affect the corporate environment in different ways depending on which political party that is in power. This brings up the question of whether political elections are important enough to affect the stock market; and it is this question we intend to analyse in this paper.Purpose:The purpose of this paper is to investigate whether political elections affect the stock market and to discuss the reasons for any possible affect that might be found.Procedure:An appropriate and thoroughly tested method to investigate if an event affects the stock market or not, is to do an event study. Subsequently we chose to do an event study on whether the Swedish general elections in 2002 and 2006 affected the Stockholm Stock Exchange. In order to give the analysis more depth we have also chosen to interview people with knowledge of the stock market.

Miljö- och Personalreglering i Förvaltningsberättelsen : - En studie av Svenska Börsnoterade Företag

The environmental work of companies has become an incredibly important factor in achieving reduced levels of environmental pollution. For companies the work on environmental issues began in the 1980s. During this time companies also began to show interest for the personnel, an interest that was shown in the form of attempts to disclose personnel information in economics. Earlier this information was separated from the financial information, despite the fact that the revenues are created by the employees.The purpose of this paper is to examine how well companies with a notification or a permit today account for environmental- and personnel information in their director?s report.

Bära eller brista - byte av noteringslista? : Nya resultat från svenska aktiemarknaden

Denna eventstudie syftar till att undersöka hur ett byte av noteringslista påverkar kumulativ onormal avkastning (CAR) 1 till och med 12 månader efter genomfört byte. I studien undersöks därför utförda byten av noteringsplats på den svenska aktiemarknaden under tidsperioden 1995-2009. I studien beräknas onormal avkastning delvis med marknadsmodellen (MM) som grund, men också med Fama & French tre-faktormodell (FF) för att öka reliabiliteten. Vidare undersöks om skillnader i CAR föreligger under olika tidsintervall samt om olikheter förekommer efter att berörda företag delats in i undergrupper baserade på typ av byte, industri samt storlek. Slutligen testas utifall den eventuella kumulativa onormala avkastningen är signifikant skild från noll med student t-test samt om det föreligger skillnader i medelvärde i de olika undergrupperna.

Teknisk undersökning : Rötgaskammare för småskalig biogasproduktion

Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

Kapitalstruktur : Skuldsättningsgrad och avkastning hos svenska finansbolag

In a time when economic crises relieving one another, it is especially interesting to study how companies choose to finance their operations. Since there is a lack of studies that include banks, and their capital structures, with the rest of the finance market, it is uncertain whether the theories of capital structure are applicable. Therefore, this essay aims to study whether there is any correlation between the two variables debt-equity ratio and return on equity (ROE) for Swedish corporations on the finance market.In accordance with the theorems that the professors Modigliani and Miller filed, in 1958 and 1961, which describes a clear link between debts, increase corporate value through the tax shield and indirectly increased yields. Although these theorems are the foundation of the modern research they focus on perfect markets. Therefore, this paper has also chosen to place great emphasis on theories such as Trade-off and Pecking-order.
