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.

Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. Fishes has shown increased contents of these substances, especially fat fish, since brominated flame retardants tends to accumulate in fatty tissues. They are also regarded as persistent and that gives them the ability to travel long distances. What also is really scary is that increased levels of brominated flame retardants have been detected in human breast milk. The knowledge of the brominated flame retardants is limited and not so much research has been done in this field. There are many reasons though, to keep the research going. Partly their structural resemblance to well-known toxics as PCB, but also their ability to accumulate in biological systems and enrich in food chains. In which way they affect humans we really don?t know yet.

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.

Min frågeställning var huruvida avslappningsträning är relevant för musiklärarstudenters musikaliska utveckling. Jag lät en grupp om elva musiklärarstudenter på Musikhögskolan i Piteå träna avslappning till cd under fyra veckor. Som metod för att utvärdera effekten av avslappningsövningarna använde jag mig av enkäter. Resultatet visade att de allra flesta upplevde positiva effekter, fysiska och/eller mentala i större eller mindre utsträckning. Det framkom också att undervisningen brast gällande mentala förberedelser inför konserter och uppspelningar..

The term "Project" have become a growing work model that exist in almost all bransches. A project is a work effort made over a finite period of time with a start and a finish to create a unique product, service, or result. Science shows that time limitation has an impact on humans to perform under pressure, which challanges the contributor to deliver. This report contains an examination about project management, both coming from scientific results and an external business. The point of this study is to bring ideas of improvement, which can make the work method more effective in this company..

AimThe purpose of this study was to examine the relationship between physical strain and recovery in dancers at The Ballet Academy in Stockholm, Sweden. Research questions used to guide the study were: How great is the dancers experience of physical strain? Do any of the dancers show mental or physical signs of overtraining syndrome?MethodPhysical strain was studied by letting the dancers fill out a booklet catloging their intensity during practice. Utilizing a questionnaire, data was gathered regarding preceding year. To give more nuance to the data gathered, The Profile of Mood States was used to detect possible mood disturbance.

The time we live in now is significant for its many ways of spreading information- it is indeed the era of communication. The Internet is the main reason for this evolution, where you can reach out to any corner in the world in less then a second. Information is flowing over us and we get more and more used to being in a constant accessible state. The individual might spread his own word as he wishes. From a democratic point of view this should give a great opening for everyone into the public spheer.

The aim of this thesis is to compare two time periods in thehistory of the university library in Lund and to see whatsimilarities and differences can be found. The two timeperiods will be 1883-1900 and 1933-1950. The methodsused to achieve this will be comparative method with theactor- and structure model and document analysis. Thesubjects that will be analyzed with these methods will bepersonnel and the facilities. The two questions I will try toanswer in this thesis will be: A) What similarities anddifferences can be found concerning the personnel and thefacilities in the two time periods? B) What is therelationship between the actors and the structureconcerning the personnel and the facilities like in the twoperiods?A brief background of what took place in Sweden, LundUniversity and the university library of Lund itself duringour two periods is provided.

We travel more to day than we have ever done before and there is an abundance of destinations to choose from. All -destinations have vantages and disadvantages and the things that are favourable for one traveller can be the opposite for another. So the questions are, why do we have different opinions about the same destination and what is it that makes us choose one destination before another?The purpose with this thesis is to investigate if the demographic factor age has an influence on the Swedish traveller?s opinion about winter destinations. The thesis also investigates if there is a link between the traveller?s demography and their opinion of a destination.

In this essay the renewal of the modern sacred art has been examined through the creation of three works of art from the art project ?Kyrkorummet?. The aim has been to show that renewal of the modern sacred art is best accomplished by the combination of the artist history and Bible knowledge and the open mindness of the beholder towards the new and creative, in order to communicate the gospel in modern time.The large extend of the art project demanded a selection of the art works. Therefore, three were chosen and they show the last supper and the baptism in a renewal way including both symbolism and creativity. To complete and facilitate the analyses, a theme, light and water, have been used as well as relevant theories in art history with Kandinsky as main art critic.Through the art project and it?s teaching, history in combination with present time through visits in different and modern churches, thoughts have been stimulated and the result has been new works of art that speaks of our time.

The survey aims to investigate and analyze how the image of Sweden and "Swedish character? is produced in the correspondence between Swedish immigrants and family at home, compared to how the image of America and the U.S. is produced. The starting point is the concept of identity, which is shaped by the social group a person belongs, which can lead to stereotypes are formed. How does the Emigrant describe his new life in letters home to Sweden? What comparisons are made? What memories are passed from the time at home? How does the picture changes over time? How does the stereotypes change over time? The material used are remnants and secondary sources in the form of correspondence between emigrants and their relatives back home.

BackgroundToday a common approach to solve a complicated problem is to assemble a temporary workforce in order to solve the problem by working together within a project. One of the difficulties with working in projects is to maintain the planned budget. Working hours and costs are often exceeded. Many companies presume that any certain project will succeed, a presumption that leads companies not to anticipate risks involved in a project. In companies today there is seldom time for evaluation or moderation of a project, in order to have time for evaluation there is a great need for an adequate planning of the project.IntentThe intention with this study is to create a model for planning, budgeting and evaluation of projects within consultancy companies.MethodWith the help of interviews and discussions within the group Hamnar och Byggkonstruktioner at Sweco has evidence to present a proposal on planning, budgeting and monitoring been developed.ResultsA model has been developed to ease for consultancy companies to plan, budget, monitor and evaluate projects.

Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.
