Hållbart byggande i urbaniseringens tecken ? En studie av det framtida underjordiska byggandet i Sverige
Denna rapport ger en bild av vilka olika saker byggherrar i Sverigeanvänder sig av idag för att öka den sociala hållbarheten. De projektsom studerats är Bygga om Dialogen i Malmö, Älvstaden i Göteborg,Vivalla i Örebro och föreningen Byggemenskap.Genom att intervjua en person från varje område studeras likheteroch skillnader i hur man arbetat med den sociala hållbarheten vidbyggnation. I Malmö och Örebro studeras arbetet med att öka densociala hållbarheten vid renoveringsobjekt, hur får de hela områdensom länge haft ett dåligt rykte att bli socialt hållbara där stort fokusligger på att anställa långtidsarbetslösa.I Göteborg och i föreningen Byggemenskap fokuserar man på attföra in den sociala hållbarheten vid nybyggnation och hur vi kan byggahyresrätter som har en lägre hyra än nybyggda lägenheter i dagslägethar..
Undersökning av avfallshantering i Stockholms innerstad
According to the European Union waste hierarchy, waste should first of all be minimized. Reuse and material and energy recycling come next. Lastly the waste should be thrown at the refuse tip. In the inner city of Stockholm waste handling can be done in various types of ways. The solutions vary as a result of the type of architecture of the building and its condition.
Konsten under jorden : En analys av Ulrik Samuelsons konst i Kungsträdgårdens tunnelbanestation
This study examines the work of art in the Underground station Kungsträdgården in Stockholm and discusses the observers interpretation of the art in the station. When the artist Ulrik Samuelson got his commission to shape the station he was influenced by Marcel Duchamp and the concept art. Two themes were integrated in the work of art, the actual culture life and the palace called Makalös, which was situated just above the currant station, three hundred years ago. The station was built in two stages.The first part was opened in 1977 and the second part in 1987. Panofsky´s iconographic working method has been used in this essay.
Sydafrikansk film som national cinema : En jämförande analys av ett forskningsfält
The purpose of this essay is to study the film culture in South Africa in a national cinema-context, focusing on the relationship between anti-apartheid film from 1974-1994 and the film in South Africa today. By pitching the South Africa-specific works of Lucia Saks and Jacqueline Maingard against the over-arching debate on national cinema as formulated by, amongst others, Stephen Crofts and Andrew Higson, this study aims to find whether or not a specific South African national cinema have existed, and exists today, or not. The study finds that an Underground culture of documentaries and short films made by and for the black population has been in place since the apartheid, and the distribution method on video and television is still being used to reach the black population today. By re-examining the concepts of both the national, and of national cinema to also include film on video and television, the study shows that South Africa has indeed a film culture that can be called a national cinema..
Spillvärmeåtervinning
SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed.
Kraftkabelförläggning i mark : - en studie av produktionsmetoder
The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

Effektivisering av lagringsplatser. Ett förbättringsprojekt på Mekpart AB
Aeroseum is an aviation museum located in an old military Underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.
Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet
This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus Underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.
Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern
Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an Underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.
Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk
The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.
Tidssynkroniserade mätningar i vattenkraftstationer
Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an Underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.
Trygghet och säkerhet i offentlig stadsmiljö :
To thoroughly think with safety and security in mind is an important issue in planning of public city spaces. Spaces intended to be available to all inhabitants of a city should have a welcoming appearance. Unfortu-nately, this is not the situation in many pedestrian walkways, parks and such spaces, possibly due to lack in safety and security.
This master thesis intend to examine questions at this issue ? what makes you feel safe and what causes insecurity in public city spaces. The safety aspect treats the human psychological and sociological ways of perceiving her milieu and other humans in it, and how the physical shape of her surroundings can affect the sense of safety.
En diktator, en vampyr och färgen grå : Förutsättningar för rumänsk samtidskonst före och efter 1989
The conditions for art in Romania have gone through big changes since the collapse of the regime in December of 1989. Under the Communist regime the artists had to work within a dualistic system completely unlike the one that developed in the West during the same period.Similar to the other countries of the former Eastern block, the communist Romanian state had understood the great potential that art has as a form of propaganda. Thus the regime secured full control over the art that would be allowed into the public space. In response to the confines set on the artistic expressions, a non-official art began to develop alongside the official art of the state.These two layers of Romanian art history were dissolved when Ceausescu?s regime finally came to an end in 1989.
