Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

Nuclear power production carries potential risks both for the environment and for the work force. Different safety measures are employed and they stem from local rules as well as from regulatory authorities. This work describes the development of a safety promoting tool at Forsmark Power Plant, one of Sweden?s three Nuclear power plants. We describe the development of a computer based system for Pre-Job Briefing and Post-Job Debriefing.

This assignment has been performed at location and commissioned by AttenditAB in Jönköping.

The importance has been to develop as reliable mobilecommunication as possible. The functionality that is demanded upon the mobilecommunication is:? Secured for future versions? Interoperability? Data should not be bugged, modified or disappearunnoticed? Resource efficientWe have achieved these demands by developing our own protocol that is on top ofthe TCP protocol.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

Vid utveckling av nya system finns det flera olika modeller/metoder att använda sig av, till exempel prototyping eller vattenfallsmodellen. Denna uppsats beskriver hur utvecklingen avett webbaserat system för registrering av datorer kan ske med hjälp av vattenfallsmetoden. Fokus på detta arbete ligger förutom själva utvecklandet av registret också på dokumenteringen av de olika stegen som följts enligt vattenfallsmodellen. Detta arbeteförsöker också svara på om denna modell är lämplig att använda vid utvecklingen av liknande system. Uppsatsen tar också upp fördelar och nackdelar om kan uppkomma vid användandet av denna modell..

Syftet med denna C-uppsats är att genom Pincus och Minahans resursinriktade systemteori undersöka innebörden av hur samhälleliga system tillgodoser hjälpbehov för klienter som uppbär försörjningsstöd under lång tid. Målet är att skapa en strukturerad bild av vad som är bidragande faktorer till långvarigt beroende av försörjningsstöd samt hur samhälleliga system arbetar med insatser gällande dessa faktorer.Frågeställningarna är följande:Vilka hjälpbehov framträder genom journalerna för undersökningsgruppen?Hur adresseras dessa av samhälleliga system och vilka slutsatser kan man dra av detta?Resultatet visar att hjälpbehoven som tillgodoses är av olika karaktär och att det samhälleliga resurssystemet ibland ersätter formella och informella resurssystem när dessa inte är välfungerande. Slutsatsen visar att samhälleliga system kan motarbeta varandra och att detta då blir till men för den enskilde.Slutsatsen visar också att preventivt arbete för att förhindra att långvarigt beroende av försörjningsstöd uppstår är viktigt..

Environmental management systems are a way of systematizing and streamlining an organization's environmental efforts. Within its EMS the organization determines it´s environmental policy and various environmental objectives. In order to achieve their environmental objectives the organization produces action plans that describe how they will work towards the objectives. Stora Enso Skog AB´s districts have been assigned to produce action plans for the company´s environmental objective of 90 % approved everyday nature consideration in final felling and any targets included within this objective. The purpose of this study was to investigate how the districts work with these action plans and how this could be improved.

Multiple Congenital Ocular Anomalities (MCOA) is a genetic disease that affects primarily Silver coloured horses of breeds such as the Rocky and Kentucky mountain horses. In these breeds the Silver dapple colour is very popular leading to an increase of affected horses. The major feature of the disease is ocular cysts of variable size. Large cysts also lead to a variety of secondary syndromes, for example retinal detachment. In previous studies the locus for MCOA has been mapped to an interval of 420 kb on equine chromosome six.

Moelven Skog AB is currently working actively to increase the number of certified forest owners in private small-scale forestry. This study was conducted in collaboration with Moelven Skog AB and seeks to learn why private small scale forest owners not yet have certified their forestry and what should be done to increase the number of certified forest owners. The study was conducted through a questionnaire study. The result of the study shows that information needs of forest certification to private small scale forest owners is great. Many non-certified forest owners have not even heard of either PEFC or FSC. The majority of respondents also have no education in forestry.

Inom styr- och reglerteknik är hantering av larm en viktig fråga, speciellt då fastighetsbranschen mer och mer börjat automatisera driften av fastigheterna. Det finns ett antal system på marknaden som erbjuder larmdistribution via en mängd olika transportsystem. Syftet med projektet är att undersöka om det finns alternativ till dessa som erbjuder mer flexibilitet, samt att designa en prototyp till ett system som använder denna alternativa metod. Två befintliga system analyserades och en kravspecifikation baserad på analysen upprättades. Utifrån denna designades en prototyp som sköter distributionen över Internet och en enkel implementation av en del av designen har gjorts.

IT-system kan delas upp i två huvudgrupper: Enterprise Resource Planning (ERP)-system och Best of Breed (BoB)-system. Ett ERP-system definieras som ett system vars funktioner använder en gemensam databas och kan därigenom binda ihop olika IT-system. Användaren kan då enkelt komma åt data inom den egna organisationen från sin egen arbetsstation utan att söka igenom flera olika system, jämfört med system som arbetar parallellt och inte samlar data i en gemensam databas. BoB-system a?r inriktade pa? en specifik tja?nst, men a?r utvecklade fo?r att klara av att utföra den sa? bra som mo?jligt.

This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south of Eslöv in Skåne. While my family for some time have thought about building a new milkingstable with AMS(Automatic milking system) I decided to compare the AMS with a conventional milkingstable. We are abit concerned about how many cows we should have in the new stable. Because of that I calculated with two different number of cows. I have compared three different types of milking stables: One alternative is 180 cows milked in a double eigth hearing bone milking stable. The second alternative is 128 cows milked with two DeLaval VMS-robots. The third alternative is 171 cows milked with three DeLaval VMS-robots. One salesman from DeLaval and one salesman from A-betong helped me to get marketprices on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs labour is included. The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program with predicted costs. The calulations from the program showed that the price in the milkingpit system was 51 000 sek per cow.

This thesis contains an empirical study of exhaustivity in the Swedish National Union Catalogue LIBRIS. The purpose of the study is to examine if fewer numbers of indexing terms in general lead to lower exhaustivity. The study contains two parts, the first part examine the mean of indexing terms per monography in the selection, the second examines the grade of exhaustivity within three groups with a low, moderate or high number of indexing terms. The 55 randomly selected titles were graded on a scale that was created from the indexing theories of Wilfrid F. Lancaster.
