Brytpunkten mellan två platser : gemenskap, miljö och identitet från S:a Maria sjukhus till Maria Park
The result of a short field work done in Maria Park, a place situated in the north of Helsingborg city. A comparative work, using the old S:a Maria and Maria Park. The same place, once a mental hospital, and now, at the time of the paper being written, it's a richer residential district. Is there anything left of the old mental hospital in the new community and the residents identities?.
Balansering av en storskalig vindkraftsutbyggnad i Sverige med hjälp av den svenska vattenkraften
This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.
Regressionsmodellering av dynamiska råemissioner från statiska mätningar
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.
Optimering av glödgningsparametrar för kromstål
At Sandvik Materials Technology, Argon gas is used as furnace atmosphere when heattreating hot rolled wire. Upon heating chromium steel wire, a rich oxidelayer forms on the wire surface. The abstract of this masters thesis is to enhance the understanding of the constitution of the oxidelayers and the influence of the furnace atmosphere. This will be achieved by performing a number of annealing experiments on laboratory level. Also, the aim is to understand the chemical reactions and physical mecanisms controlling the pickling process.
Social hållberhet genom medborgardialoger : exemplet Husby
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.
Renovering av flerfamiljsbostäder inom miljonprogrammet ur ett energi- och lönsamhetsperspektiv
Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.
Markberedningens betydelse och egenkontroll för markberedning
The purpose of this report is to make an evaluation of the self-monitoring for scarification which Stora Enso is using and this study deals with the effects and importance of scarification. A comparison is made in this study with the purpose to highlight any differences between some of the leading forestry companies and significant forest organizations in Sweden. The companies represented in this report are Korsnäs, Mellanskog, SCA, Sveaskog and Södra.
In the beginning of this study an interview form was set up together with Daniel Forsberg at Stora Enso. Stora Enso is the head object of this report and seven interviews were made within that company. At the other companies only three interviews were made within each one, with an exception to Mellanskog who wished four.

På färd genom glömda landskap : Rumslig analys av bronsåldersbygden i Mönsterås
This paper deals with the relations between landscape rooms and monuments in an area north of Mönsterås in Kalmar län. After archaeological excavations had been carried out in the area 1991, an article promote it to the ?Bronze Age district of Mönsterås? (Källström 1993). There are two main problems that I deal with in this paper. First: The relations between the natural places and the monuments or memorials.
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.
Risk- och sårbarhetsanalyser för smarta elnät
The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a smart grid. With the transition to a smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.
Analys av bostadsrättspriset i Stockholms innerstad : En multipel linjär regression
In this study a multiple linear regression was carried out in the interest of analysing a number of variables effect on the final prices of apartments in Stockholm?s inner districts. The result may be employed to predict and observe percentage changes on the final price of apartments in Stockholm in the future. Five models were constructed after which they were analysed and compared. The construction of these models were supported by data from the real estate agency Erik Olsson.
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 I GRANSHOT® - PROCESSEN
Uvån Hagfors Teknologi AB (UHT) has developed a process ? GRANSHOT® ? for quicksolidification of metals in water baths. In the process liquid metal is splintered ? granulated ?into small drops. The drops are rapidly cooled in a water bath where all the heat energy from theliquid metal is transferred into the water.
