Filter och kapsling för IR-givare
This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application.
Effects of ten year old enrichment plantings in a secondary dipterocarp rainforest : a case study of stem and species distribution in Sabah, Malaysia
Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).
Prestationsbaserad självkänsla, kompensatoriska strategier och återhämtning i det gränslösa arbetet
Gränslöst arbete innebär att ansvaret ligger hos individen och denne själv kan bestämma var, hur och när arbetet ska utföras. Prestationsbaserad självkänsla bidrar till utmattning och sömnsvårigheter och att använda sig av kompensatoriska strategier är ett sätt att hantera gränslösheten. Syftet med studien var att undersöka sambanden mellan prestationsbaserad självkänsla, strategier och återhämtning bland personer med gränslöst arbete. En enkätundersökning genomfördes. Deltagare var 93 män och 47 kvinnor som arbetar på ett privat företag inom säkerhet och utbildning.
OneCore
The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.
Energiåtervinning ur våtluft vid pappersmaskin
Övik Energi AB driver i Husum ett fjärrvärmenät som tillföres energi från M- reals pappersbruk i Husum. Värmen produceras dels genom återvinning av torkluft från en av pappersmaskinerna och dels i en ångvärmeväxlare. Andelen återvunnen värme kontra prima värme antogs, innan fjärrvärmenätet togs i drift 1992, uppgå till 80% respektive 20% vardera. Andelen spillvärme har emellertid visat sig vara betydligt lägre än dessa 80%. Som exempel har andelen under tiden 1998-2001 varit ca 55% av nätets totala värmebehov på 7000 MWh/år.
Recovering common ground : landscape architecture as a tool for post-conflict recovery and spatial reconciliation in divided cities
The following chapters examine landscape architecture
which engages in contested territories with an emphasis
on the way in which landscape architecture can engage
with the issues of divided cities or landscapes with similar
social, cultural and physical properties. The project focuses specifically on the potential landscape architecture
has for promoting or aiding in the reconciliation process
of these areas, by examining the following questions.
How can landscape architecture be used to benefit the
peace building process of divided cities and landscapes?
How can landscape architecture be used in the process of
promoting spatial reconciliation in the case of Belfast?
The investigation begins with a description of the background to the project in Chapter 1, which functions as a
brief introduction to the urban phenomena that is divided
cities. It then goes on to introduce the different methods
and data employed in order to answer the research questions
in Chapter 2.
After introducing the problem and the methodology, a
global overview of divided cities is performed in Chapter
3. This chapter is divided into two sections.
Hypotermi vid anestesi av hund
The reasons for hypothermia during general anaesthesia are many and varied. The lowered body temperature causes negative physiological effects and leads to discomfort for the animal during the recovery period. This student report is a combination of field study and literature review. In the field study the changes in ambient temperature and the rectal temperature of dogs were monitored during general anaesthesia. The purpose of the study was to see if the body temperature of dogs was reduced during general anaesthesia.
Energikartläggning av en livsmedelsindustri : samt förslag på energieffektiviserande åtgärder
This thesis concerns an energy audit of a food industry. The company's business consists of boiling and peeling shrimps, and producing mayonnaise-based salads. This type of work involves energy-intensive processes, such as steam generation, compression of air and refrigeration of large spaces. These needs are supplied with electricity. Furthermore, the industry is a major consumer of district heating, particularly for heating the supply air in the ventilation system.
Simulering av en framtida presslinje - en analys av design och prestanda
Problem areaAlfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manage. To build new lines cost a lot of money and take time so it is essential that new lines are correct from the start and not need to be rebuilt or a lot of time spent to trim it.GoalThe goal is to achieve 100% theoretical utilization of the press (the press shall press the amount of plates it is designed for).
Integritetsstudie av Ceph : En mjukvarubaserad lagringsplattform
Dagens moderna organisationer driver vanligtvis en kostsam IT-baserad infrastruktur. De besitter högpresterande funktionalitet och säkerhet för att garantera att de dagliga operationerna fortskrider. Mjukvarubaserade lagringsplattformar är ett alternativ som kan användas för att reducera dessa kostnader. Genom att efterlikna avancerad teknik som redan existerar i traditionella lagringsplattformar kan detta implementeras som mjukvara på commodity hardware i syfte att uppnå samma funktionalitet. Ceph är ett alternativ som numera implementeras och ämnar erbjuda detta val.
Att ta ställning
Socialstyrelsen, i sin roll av tillsynsmyndighet för den läkemedelsassisterade opiatvården, utfärdar riktlinjer för detta arbete. Av dessa framkommer vissa skyddsfaktorer av särskild vikt, vilka har operationaliserats i en factorial survey med en randomiserad och en standardiserad vinjettkomponent. Dessa bedömdes av yrkesverksamma inom underhållsbehandling, totalt 38 personer. Materialet bearbetades genom multipel regressionsanalys. Resultatet visade att tre av variablerna - psykosocial intervention, boendesituationen samt familjen/nätverkets stöd, har ungefär lika stor påverkan på bedömningar.
Infallsvinklar och angreppssa?tt fo?r en svensk livsmedelsstrategi : En utredning av angreppspunkter och betraktelsesa?tt hos livsmedelsstrategi-intressenter samt ha?llbarhetsaspekter av dessa.
Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

Modellering av indunstning på Södra Cell Mönsterås
Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.
