Chalmers oanvända datorkraft - Distribuering av arbete och energihantering med HTCondor

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.

Motiverad för riskmedvetenhet? En studie om stadsarkitekterna i Dalarnas läns medvetenhet om, motivation för och arbete med risker vid fysisk planering.

The purpose of this study is to examine how risk is perceived by the urban architect's in the region Dalarna, as well as how this is reflected in their everyday work with risk and decision- making according to urban planning. The ambition is also to show how their risk awareness could be improved. The study is written in cooperation with Länsstyrelsen Dalarna as a part of their regional long-term goal to improve the region's proactive risk' and crisis management. The study is based upon 12 semi-structured interviews with local urban architects conducted during the summer and autumn 2007. The result shows that some architects are motivated for working with risk and think that risk awareness should be integrated in their everyday work, while others are not motivated and think that risk is more of a passing trend.

Ägandeskap av data i molnet - En studie om företags attityder och resonemang kring ägandeskap när de placerar sin data i molntjänster

Cloud computing has become a very publicized and popular concept in recent years, both in business literature and research, where data ownership is the security aspect which has usually been ranked the highest of the disadvantages that can be identified with cloud services. Today there is a lack of research on information ownership from an informatics perspective, as it is most often discussed from a legal perspective.In our study we interviewed six different companies that use cloud services, on which attitudes and reasoning they had on their information ownership. We compared these attitudes with the attitudes we identified in business literature and research on the subject. In business literature we found four recurring themes which were very clear about how a company should govern information ownership.Overall the results of our interviews showed that there is widespread ignorance at the companies on how information ownership in the cloud is regulated between the company and the cloud provider. All companies expressed that they had not experienced any change in ownership when they placed their data in the cloud, and they expressed no major concerns about how the ownership was handled.

Friluftsvanor -I storstad och på landsbygd

Outdoor recreation habits in metropolis and rural areasThis study aims to examine the perception of nature and outdoor recreation habits from an urban-rural prospective. The urbanization process continues in Sweden and the populations of the cities are growing continuously. Trends to build more compact and ?climate smart? reigns and with this a risk that green areas and areas where outdoor recreation can be practiced are situated further and further away from the urban population. Analyzing the responses from a survey made by the research program Friluftsliv i förändring 2007 we have examined if and which differences exists between urban and rural areas regarding their perception of nature, outdoor recreation habits and factors influencing the practice of outdoor recreation.

Tillit och misstro till molntjänster : Identifiering av vilka kriterier som skapar tillit till molntjänster

Cloud computing innebär att datorkraft och IT-resurser i form av servrar, lagring och lokala nätverk görs tillgängliga via internet, cloud computing har ökat snabbt i användning de senaste åren. Möjligheterna med molntjänster har lett till nya utmaningar avseende tillit till molntjänster genom att öppna för helt nya förhållanden mellan leverantör och kund. I dagsläget så är tillit till molntjänsterna ett stort problem för kunder såsom mikroföretag samt små och medelstora företag.Vårt examensarbete syftar till att beskriva mikroföretags samt små och medelstora företags tillit och misstro till molntjänster, samt identifiera vilka kriterier som bidrar till detta. Resultatet visar att det är svårt att tydligt definiera tillit och misstro hos företag, då deras situationer och verksamheter skiljer sig. Tack vare vår litteraturstudie i kombination med våra intervjuer har vi skapat oss en bra bild av vilka kriterier som bidrar med tillit och misstro till molntjänster.

Nya träd för stadsmiljö

Trees in urban environment are exposed to extreme conditions, foremost the ones that grow in the hard packed soil along our streets. They are also exposed to damaging insects and fungal diseases both local and new ones spreading from South Europe. The global warming with warmer temperatures provides a longer growing season, making it easier for insects and fungus to establish a habitat. Based on these facts new tree species need to be available for future urban plantings.To determine what these trees would be an interview study began. Six people were selected who have experience in the field of urban environment planting.

Användandet av ickesanktionerade molnapplikationer inom svenska organisationer

Molnapplikationer som DropBox har under de senaste åren blivit allt mer populära ocherbjuder anställda möjligheten att kunna kommunicera och dela filer mellan varandra.För att få en förståelse för hur icke-sanktionerade molnapplikationer användspåbörjades en undersökning för att identifiera risker och möjligheter för svenskaorganisationer.Denna uppsats genomfördes med en kvalitativ ansats och inleddes med enlitteraturstudie som följdes av nio stycken intervjuer med personer som har erfarenhetav IT-infrastruktur och Cloud Computing. Resultatet indikerade att IT är intressant förorganisationer där man önskar ha en bättre kontroll över kostnader och resurser samtkunna förändra vid behov. Om organisationer inte implementerar en policy för huricke-sanktionerade molnapplikationer ska hanteras kan anställda välja att skapa sinaegna regler och att man därför tappar kontrollen över data.Genom att analysera och se över sina nuvarande behov kan organisationer behållakontrollen över data, samtidigt som man undviker att det blir dyrare och kan minskakostnader samt skala sina resurser beroende på behov.Exempelvis kan framtida forskning vara att man undersöker hur användningsscenariotser ut på arbetsplatsen kontra hemma och vad det är för typ av resurser som behövsinom organisationen..

Tillväxt som strategi

Uppsatsen behandlar temat urbana tillväxtstrategier i svensk planering. Studien syftar till att undersöka hur översiktsplaner har påverkats av entrepreneurial city, platsmarknadsföring och kreativa klassen som alla är olika teorier om urban tillväxt. Undersökningen utgår ifrån fem kommuner med en översiktsplan från tidigt 90-tal och en aktuell plan antagen omkring 2010. Översiktsplanerna studeras utifrån de valda teorierna (entrepreneurial city, platsmarknadsföring och kreativa klassen) om urban tillväxt för att ge förståelse för hur strategierna i kommunernas översiktsplaner har påverkats av teorierna. Den genomförda undersökningen visar på en förändring över tid som pekar mot mer tillväxtorienterad planering..
