Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.

Derome Skog AB is a purchase company whose main task is to provide Derome Timber's sawmills in Halland with timber raw material. Because of the very hard competition in the roundwood market it is important to know what kind of purchase offers are required in order to buy a valuable product from forest owners.This study aims to elucidate the crucial factors when private forest owners choose to harvest and sell their forest. As base for this study, a questionnaire has been performed with private forest owners. The result of the study shows that it is not particularly often that the timber price is the crucial factor why the forest owners choose to harvest and sell the forest products; i.e. timber, pulpwood as well as energy assortments.

The essay's aim is to explain how responsibility distribution between private and public bodies, primarily within three important service areas, can be visualised in light of the fact that they have experienced different forms of readjustment. We have chosen to study this by looking at the restoration work taking place after the hurricane Gudrun swept across southern Sweden on January 8-9, 2005; and we have chosen to concentrate on the service areas of electricity- and telephone supply, and public transport. The responsibility distribution has been depicted by carrying out qualitative interviews with employees within both private and public bodies included in the restoration work. The conclusion produced is that there were obscurities in the formal responsibility distribution between private and public actors taking place in conjunction with the hurricane restoration work.In a deeper analysis, the result can be explained by a ?several hands? problem arising since the number of actors has increased as the public sphere has adopted leadership forms influenced by the private business sector.

Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.

The purpose of this study has been to investigate how psychosocial support for families where a parent suffers from a life threatening illness can be constructed. The intent was also to explore how the child's perspective is protected and what barriers and opportunities there are for family oriented support. The study has a qualitative approach and includes interviews with four social workers. The interviews were analyzed with a systems theory and attachment theory. The conclusions are that the whole family suffers psychological and social pressures when a parent is sick.

Earth?s resources have been exploited unsustainably. If an entire conception of exploitationof natural resources does not change now, this will entail enormous costs in the future.This insight has lead to a recently increased interest in clean technologies among privateequity capitalists. In the fourth quarter of 2006 about 10 percent of all private equityinvestments made in the US market were placed in the cleantech industry. Despite a goodinvesting climate in Sweden, Swedish capitalists have shown little interest in cleantechinvestments.

Even though Sweden is a small country which has a low rate of inhabitants is it one of the worlds leading nations of exporting products from the forest industries. The Importance of a sustainable use of the Swedish forests has been known for many years. In 1903 the first law of forestry were establish. Today the National Board of Forestry carry out inventories of regeneration result. The result of the latest inventory showed that especially the non-industrial private forest owners did not full fill the regeneration work after a clear cut.

This study is one of five that has been done based on Lunds Energi?s planned investment in bioenergy. The plan is to build two large burners, at Örtofta, that?s going to be supplied with biofuels. In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage sludge.

This study aims to further Work-family conflict research for Social Workers by providing insight into what kind of impact the job role of social workers in Sweden has on their private lives and how they deal with it. The study operates from a qualitative approach and is based on three focus group-interviews and three semi-structured interviews with people working in different fields of social work. The empirical material has been analyzed through the Dramaturgical Perspective and Frame concept of Erving Goffman. The results of this study show that the job role impacts the psychological well-being of social workers, their family life and their social life to varying degrees, mainly due to organizational and client-based aspects, often resulting in role-conflicts and a lack of energy in their private lives. The primary strategies were found to be conversing with colleagues, spending time alone, embracing hobbies and having a clear understanding of individual responsibility. .

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

This paper is a research review in the realm of censorship systems andfiltering systems. It applies ethical considerations to the creation of censorshipsystems bringing forward discussion on the ethics of technology with thepurpose of limiting access to information.There is active research being done in the area of automatic content filteringand censorship systems. These are systems that can filter out undesiredmaterial, typically from the Internet, automatically. Used in some nations,many schools and even mandated in some libraries there are many ethicalquestions raised concerning censorship and access to information.Part of the review concerns the level of accuracy of these systems presentedby researchers in the field and the different approaches used. Reviewedarticles centre around automatic content classification and filtering ofpotentially harmful materials with regards to minors while some relate tocensorship technology in a wider sense.Results show a general lack of discussion concerning the ethics of thetechnology in the research reviewed.

This study examines use and users of information and records originating in the context of a contemporary police organisation. This area of research has only been of focus for a relatively few researchers. This in contrast to use and users of historical archives which has been in centre for more studies. The study is conducted with a quantitative method structuring data from 120 selected registered matters containing user queries. The research questions addressed are:- what user categories use the records of the authority- which are the ways of contacting the authority preferred by the users- which are the identifiers provided by the users and how well are they matched by the search artefacts available to the staff of the authority- what information and records are sought-after by the users.For comparing the identifiers provided to the search artefacts has been selected the two most frequently used registry systems within the authority.

In this essay we discuss how the decentralisation of the Swedish school system affects the concept of ?equal opportunity school?. We investigate the development from both a historical and contemporary perspective, in order to identify changes over time. The central question of the essay is how the decentralisation of the school system affects the teacher?s perspective and experiences of the government?s framework about ?equal opportunity school?? The analysis is based on four qualitative, semi structured, direct interviews with respondents both active in municipal schools situated in the Malmö council and with more than thirty years of experience in their profession. Our analysis of the interviews show that both respondents experience the overall situation in the schools has deteriorated from an equal opportunity aspect since the decentralisation of the school system.

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.
