During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

BedZED är ett område utanför London som har tagit upp viktiga frågor vad det gäller klimatförändringar. Vad kan befolkningen göra för att minska förstöringen av ozonlagret? Men de försöker även åtgärda andra problem så som: energiförbukning, växthusgasemissioner, vattenförbrukning/-förstörelse, överdrivet utnyttjade av naturresurser för att producera livsmedel, foder och komsumtionsvaror, transportsektorns förbrukning av fossil energi och luftföroreningar etc. En viktig aspekt är att köpa närproducerat för att slippa utsläpp av avgaser vid transport av livsmedlen. Detta arbete visar hur tre typhushåll har tänkt med odlingen av grönsaker och rotfrukter när det är en så pass begränsad yta att odla på. Ytan är sex kvadratmeter.

Antalet återvinningscentraler har ökat de senaste åren och vid utformning av dessa finns det en god möjlighet att utnyttja kunskap från industri och forskning inom arbetsplatsutformning och godshantering. Inom återvinningsbranschen finns det många arbetsmiljöproblem som visar sig i arbetsskadestatistiken. Ett problem är bristen på ergonomiskt lämpliga hjälpmedel för personal och besökare. Denna brist på hjälpmedel leder till arbetsskador och olyckor på ÅVC:erna. I dagsläget kan man bryta ner dessa problem i fem uppgifter,1.

För att undersöka möjligheten att använda sig av membranfiltering vid Gäddviks vattenverk (Luleå kommun) har ultrafilter från två olika leverantörer utvärderats. Denna rapport behandlar de 6 första månaderna av anläggningarnas drift. De två leverantörerna är Zenon GmbH och Inge AG. Vid drift av anläggningarna har det största bekymret varit igensättningar (fouling) av membranen. Igensättningar måste kunna åtgärdas för att långvarig drift av membranen ska vara möjligt.

Nowadays the world of football has become more commercial than before. As a result of this the clubs' financial status is getting more and more important. Therefore the UEFA has given the national federations a specific task to make sure that the clubs from each country follow certain standards of maintaining the football credibility. The Swedish federation has decided that the Swedish clubs must follow the so-called ?elitlicensen?.

The application of performance-based pay system among enterprises is becoming more frequent. Performance-based pay systems is used by organizations in hope of increasing productivity and have become more flexible. Employees may perceive the performance-based salary as a motivator or a threat depending on lifesituation and personality. At a perceived threat, the employee may become stressed. Work-related stress has become a serious social problem that can have consequences for both companies and individuals.

Ambulanspersonal skall i sitt dagliga arbete lyfta och behandla patienter. I varje ambulans finns två ambulanssjukvårdare (kan även vara sjuksköterskor med eller utan specialistutbildningar) som har genomgått ett lyftprov som bekräftar att de på två man klarar att lyfta en patient som väger 90kg. Då en patient väger 150kg (gravt obes patient) eller mer blir det problematiskt, både ergonomiskt och medicintekniskt. Antalet överviktiga ökar, även de som räknas som gravt obesa. Syftet med denna uppsats vara att beskriva ambulanspersonalens erfarenheter då det gäller ambulanstransport av gravt obesa patienter.Enkäter besvarades anonymt av personal på en ambulansstation i södra Sverige.

Med globalt ökat klimathot och ett ökat användande av biologiskt nedbrytbara material för att bland annat driva vår motorpark och värma våra hus kommer även ett krav på ökat produktion av utsläppsreducerande (koldioxid CO2) material så som biobränsle.För att kunna reducera utsläppen krävs inte bara att vi ökar produktionen av biologiskt nedbrytbart ämnen utan att dessa material har de egenskaperna som de förbränningssystem de används till optimalt kräver.Ett av de biologiskt nedbrytbara materialen är biobränsle, framställt av skogsavfall (grot). Dess hantering ifrån avverkningstillfället tills in- transport till förbränningen har varit kärnan i detta arbete. De två grundfrågorna som har varit själva motorn i arbetet har kretsat kring;o Vem äger vad i olika hanteringssteg?o Vem vet vad i olika hanteringssteg?Syftet med denna undersökning var att bland annat försöka få reda på svaren på frågorna ovan men även att väcka ett ökat intresse och förståelse kring hanteringen av biobränslet från avverkningstillfället fram till in- transport till en terminal alternativt direkt in till panncentralen.Undersökningen gjordes genom en enkätundersökning på Internet. Enkäten skickades ut till berörda parter i Sverige per e-post och adressaterna kunde svara direkt i datorn och skicka tillbaka enkäten utan att skriva ut den.

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.

This master thesis sets out to compare the different public transport modes in Stockholm city.Both energy consumption and air pollution are compared. The chosen transport methods are car,bus and metro.Traditionally the rail industry has had environmental arguments as a strong competitiveadvantage when it comes to passenger transportation. However, in recent years the automotiveindustry has been getting more positive media attention regarding environmental issues, forexample Roger Kemp?s statement that the car is the most environmental friendly passengertransportation mode in the UK. This study will show the environmental advantages of railwaytraffic in cities.The energy sources of the world are not endless and the use of the different sources affects theenvironment in different ways.

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.

Public health focuses on interventions related to physical activity during leisure and at work under conditions where health care is offered during working hours. Increased physical activity offers many positive effects on health in general and reduces the risk for most injuries and illnesses. Female cleaners represent a profession that is largely composed of women at high risk of overload injury and rarely participate in wellness initiatives offered at workplace. The purpose of this study was to investigate the effects of 20 minutes of daily physical exercise for 10 weeks of intervention for healthy female cleaners. A total of 40 female cleaners in a larger organization participated in the study and were divided in into an intervention group and a control group.

Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.

Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.

The aim of this study was to enlighten social workers experiences of social networks direct influence in Swedish social services, and in which ways those influences are manifested. Some of the issues that are being explored in this study are: The separation of the private sphere and professional duties; boundaries and dual relationships that occurs inside social networks; the use of social networks as a control-instrument in authority exercise towards clients; and social networks arising impact on social work. The empirical material was collected with nine qualitative interviews with social workers stationed at different social service departments in a Swedish municipality. Also one qualitative e-survey was sent out to, and answered by four social workers with a managerial position in the same municipality.The results reveal that several informants have experienced different problematic situations involving clients within the social networks. This study shows that the informants are very restrictive with what information (text and pictures) they publish on their facebook-profiles, because of their position of authority and the awareness of the possibility of always being watched.
