Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

This is a non-traditional examination paper written after three years of studies at Malmö University and the Kaospilot Program. It is written in Swedish and in the spring of 2009. It describes a non-linear project based on a process-orientated theory called Theory-U by Otto C. Scharmer (2009). The project aims to investigate the changing conditions of Stage Theatre and deals with non-linearity as phenomena.

Det här examensarbetet har utförts vid SCA Hygiene Products:s produktions-anläggning i Lilla Edet. Där trä och återvunnet material förädlas till toalett- och hushållspapper för konsumenter och industrier. Bakgrunden till projektet var att de anställda vid konverteringen var överrepresenterade vad gäller belastningsbesvär. Projektet var avgränsat till tre av produktionslinjerna vid konverteringen. Vilket omfattade ungefär 55 operatörer som arbetade 5-skift.

This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different networks and the efficiency was measured. The network represents an enterprise network that uses the operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.

Through an examination on a Telemarketing company this paper aim to investigate which relations there is between the level of motivation and performance and how these are related to the factors that are included in Herzbergs two-factor-theory.In this essay we have been using a questionnaire and interview. We have also been able to collect statistics on employees from the Telemarketing company we examine. On the basis of these data we have analyzed which relations there is.The examination shows on relations who mean that the factors Performance and Acknowledgement are the ones that affect the motivation the most, and therefore the level of Performance. The rest of the Motivation factors don?t show any clear relations.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Den vanligast förekommande smittspridningen sker via händer. Trots stor kunskap om vikten av handhygien bland sjukvårdspersonal har olika studier visat att följsamheten inte motsvarar det förväntade. Syftet med den här litteraturstudien är att belysa läkares och sjuksköterskors kunskap om, attityder och följsamhet till handhygien samt att belysa eventuella skillnader. Arbetet omfattar tio vetenskapliga artiklar från Europa och Nordamerika samt litteratur för att besvara uppsatsens frågeställning. Resultatet i den här uppsatsen visar att både läkare och sjuksköterskor har relativt goda kunskaper om handhygien men där läkare och sjuksköterskor jämförs har sjuksköterskor bättre kunskaper. De vanligaste orsakerna till negativa attityder är tidsbrist samt torr och irriterad hud p g a handtvättningsmaterial.

Energy awareness is growing among the Swedish population and a one­?to­?two-family dwelling can save energy. The purpose of this paper is to design a tool that helps these home owners reduce their energy costs.The paper develops a model that gives them an indication of how much energy they can save. For the majority of homeowners, the next step in the quest to reduce theirs is most likely an energy audit. Therefore, information to help home owners to get a good energy audit performed is included in the model.A prototype running the operating system iOS is created and validated against existing models, as well as an energy audit. .

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

Arbetet bygger på att de informationssystem som används idag men som blir allt äldre och därigenom inte klarar de krav som ställs på dem. Detta medför att informationssystemen måste migreras till modernare plattformar, då företagen dels inte klarar sig utan dess nuvarande funktionalitet och dels måste vidareutveckla systemen.Detta arbete tar upp olika sätt som detta kan genomföras på och vilka problem som kan komma att uppstå när detta sker. För att kunna undersöka detta så genomfördes ett antal migrationer. Språken som migrationen kommer att ske mellan är Visual Basic 6 och Visual Basic .net. Migrationerna kommer att ske med hjälp av ett migrationsverktyg, samt ett ramverk som i arbetet skräddarsys för just arbetets typ av migrationer.Det arbetet kommer fram till är att det sker problem vid användande av ett verktyg och även att det inte ger tillräckligt med respons på vad som gått snett under migrationerna..

MPC is the company Exova Metech?s operating system that contains all the information needed for the company's objectives and guidelines to permeate the company. How changes in the MPC should be communicated with the company's employees can be seen as problematic. Routines that have been changed in practice, the process owners do not always update in the MPC, it leads to that the employees can not ensure that duties are performed properly. It is therefore important that management takes its responsibility by providing updated information.

This thesis has been done at the Unversity of Örebro for Örebro University Hospital (USÖ). In our work we have developed a product for hearing tests to determine hearing thresholds of small children. Our product contains software and a control surface for controlling two separate screens. One of the demands was that our software could handle big file libraries. Reliability and simplicity were essential for the user.In our work we have utilized programming of both microcontrollers and Windows software.

Syftet med denna litteraturstudie var att sammanställa vetenskaplig kunskap om hälso- och sjukvårdspersonals attityder gentemot handhygien. Resultatet baseras på 10 st vetenskapliga artiklar. Resultatet visar att sjukvårdspersonal har en positiv attityd till handhygien vid patientkontakt eller vid exposition av kroppsvätska. Däremot finns en negativ attityd vid användandet av handskar, tro att handhygien orsakar hudirritation och när handhygiensmedel ej finns lättillgängligt. Personalens attityder påverkas av vilken kunskap de har och deras arbetsledares åsikter gällande handhygien.
