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.

Many IT projects that have been developed in recent years are often considered to be unsuccessful. According to a study by Exido up to the 72% of all IT projects are considered to be failed. A failed IT projects means that the organizations that have ordered the new system may have higher costs or/and the system will not be ready in time. If costs are too high the new system might not be installed in the organization or if the system is not completed within the specified time frame the organization can become stagnant.In this paper we conduct an investigation of the failure of IT projects there we will examine where, in the systems development lifecycle four different phases, projects fail. We will conduct an empirical study of each phase, where we describe the key steps in the process; we will also investigate failed IT projects that are linked to the current phase.

The thesis aims to investigate the farmer?s perception of currency hedging and interest rate bonds and to investigate the farm size of companies categorized by number of acres, has no effect on this. The work also aims to gain an insight into what active farmers consider to be important what to consider when they choosing a bank and a personal banker. The work is based on the survey and has been supplemented by a literature review on the subject. For the survey were selected out randomly 50 farmers with Agriculture and Rural Management education. The requirement of the farmers was that they should be farmers by profession, and also made sure that the farmers of various sizes came with. We got a total of 32 responses within the set response time we said, which was better response than we expected. When the final result came we ranged the farms in a size range. We found out that all farmers in the study diligently follow the market and are easy to assimilate new ideas, providing opportunities to profitability of their business with the different instruments that are available on both the financial level and farm level. The investigation revealed that the major in favor of having a personal banker. They think it´s good to have a special plug to turn to who has knowledge and experience of how the agriculture sector operates.

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..

Detta examensarbete är utfört på Saab Training Systems AB i Huskvarna. Saab Training Systems utvecklar, tillverkar och säljer kompletta militära träningssystem.Syftet med arbetet var att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande reserv- och reparationsflöde samt att identifiera problem och komma fram till förbättringsförslag.Vidare har vi studerat reservdelslagrets lagernivå och dess kapitalbindning.Arbetet genomfördes med hjälp av intervjuer med berörd personal, observationer, enkätundersökning samt statistiska studier. Vi har även arbetat med Supply Chain Operations Reference Model som är en öppen referensmodell med vars hjälp man kan kartlägga, förändra och optimera sin verksamhet.Saab Training Systems har som mål att ledtiderna för reservdelsflödet och reparationsflödet skall vara 14 dagar, men i själva verket är det inte så. Dessa ledtider är idag längre, hur långa är dock oklart.De långa ledtiderna beror främst på att i flödena förekommer det mycket passiv tid.

This thesis deals with the goods classification of the Nordic alcoholmonopolies, viz. Alko in Finland, Rúsdrekkasøla Landsins in the FaroeIslands, Systembolaget in Sweden, Vínbúðin in Iceland, andVinmonopolet in Norway. The focus of the study is the web pages of thecompanies (as they appeared April 10th 2011) and the printed pricecatalogue of Alko, from which information on class division has beenexcerpted. The emphasis lies on the division into product groups and theinformation about origin. Within these facets, which partly overlap insome of the classification systems, the principles of division and thehierarchical relations between classes are studied.

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

AbstractTitel: The optimal salary system in the real estate industry Authors: Emma Bjo?rkman och Tere?se Emanuelsson Widstro?m Tutor: Tommy BergquistProblems background: The challenges companies face is to recruit, retain and motivate empolyees to work in a way that promotes the company. Skilled staff are difficult to recruit, more difficult to maintain and expensive for companies to lose but undeniably the most important key to success. How should the optimal salary system be composed to attract operators in a competitive market such as real estate industry, with a predominance of commission based salary?Purpose: To examine how the salary system is linked to motivation and goals in the real estate industry.

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

During the last few decades a new kind of business operation have developed and this hasforced organisations to adapt themselves to a new competitive environment characterized byincreased customer demands as well as a larger amount of competitors. Therefore companieshave had a shift in their strategies from focusing on sales numbers to focusing on thecustomer. To build lasting customer relationships, in order to create customer loyalty, havebecome an important part of the organisational strategy and the collection of consumer datais essential in achieving this loyalty. Customer relationship management systems assistorganisations in managing information about individual customers as well as managing allaspects of customer contact, with the purpose of increasing customer loyalty towards thecompany. The collection of consumer data also enables for companies to design personalizedoffers to individual customers in the form of direct marketing.
