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.

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

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.

Syftet med denna uppsats är att visa hur maskulinitet gestaltas i filmtrilogin Härskarringen och att undersöka huruvida karaktärerna är nyskapande eller stereotypa. Härskarringen valdes ut i samband med en större undersökning bland manliga gymnasieelever. Vi använder oss av en kvalitativ analys av de tre filmerna. I Härskarringen presenteras en stereotyp bild av maskulinitet där typiska manliga karaktärsdrag är att vara ädel, fysiskt stark, modig, lojal, ödmjuk, potent, intelligent, beskyddande, respektingivande och med en stark vilja att kämpa för det rätta..

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.

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..
