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.

Sveriges befolkning blir allt äldre och år 2050 beräknas en fjärdedel av befolkningen vara över 65 år. Detta medför ett ökat behov av tillgänglighetsanpassade bostäder som till exempel mellanboende. Samtidigt håller sig Sveriges befolkning friskare och på grund av detta minskar vårdbehovet och efterfrågan av särskilda boenden. Trygghetsboende är en typ av mellanboende. Det är till för människor över 70 år som känner sig i behov av ett tillgängligt utformat boende och kanske känner sig ensamma men som av kommunen inte anses i behov av ett särskilt boende.

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.

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.

This project includes a small study of Västerås city's housing needs, and a proposal on theuse of the property 1:207, Lantmännens silo in the Eastern Harbour, Västerås.The project intends to produce a basic study of the useful systems for this rebuilding projectwith regards to sustainable development and energy saving light buildings.The end result, which consists of a detailed visualization of the proposal, intends to becomean iconic natural focus for the Eastern port of Västerås and an example of the use andadaptation of existing structures.The property must also link the eastern parts of Västerås with the center through anextension of Mälarleden.The work has been performed through literature studies, site visits, contacts with the City ofVästerås and by calculations.The proposal consists of architectural proposals drawings and visualizations.Furthermore, a suggestion is given of how the property can be used and fitted into theoverall plan for urban density development currently underway in the city of Västerås.Computer programs used have been Microsoft Office Excel, AutoCAD and ArchiCAD..

This thesis is a study of residential environments and a design concept for a proposed housing area in Tierp. The industrial era created a need for the central planning of housing. The confined environments that arised in cities during the 19th century, together with modernistic and democratic ideas, led to regulations in planning and housing. Though the overall goal has been the same: to create a good standard in living, the ideas of how to achieve that have varied. The starting point for following generations has been to attend to the insufficiencies of the earlier planning periods.

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..

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

This thesis aims to increase understanding and knowledge of issues affecting the redevelopment of older office buildings to housing. The rising demand for housing in recent years has resulted in a need and an increase in cost housing projects. The need has led property owners wanting to build old office buildings to apartments. The case study is carried out in Lycksele town and in close contact with consultancy TM (Technician Mercantile) ? consulting, which has operations in the area.
