Malmö stadsbibliotek och framtiden ? En diskursanalys av två stadsbibliotekariers tankar och visioner

The aim of this master?s thesis is to examine the discourses aboutthe future of Malmö City Library expressed by the chief librariansSven Nilsson and Elsebeth tank. Furthermore, our intention is tostudy the relation between the two. The questions posed in thestudy are: how does chief librarian Sven Nilsson express the futureof Malmö public library between 1989-1997? How does chieflibrarian Elsebeth tank express the future of Malmö City Librarybetween 2008-2010? How does Sven Nilsson?s and ElsebethTank?s thoughts and visions of the future correlate?Our theoretical and methodical building ground is in the discourseanalytical field, with Ernesto Laclau?s and Chantal Mouffe?stheories about discourse and society, as startingpoint.

Analys av nivåproblematik i dränagetank på Ringhals 1

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

En ny metod för att designa rakettankar

I denna rapport beskrivs ett ny idé för rakettankar. Beräkningar och simuleringar görs för att avgöra om idén håller. Idén går ut på att sätta en tank i en tank, för att på så vis möjliggöra en arbetfördelning mellan den inre och den yttre tanken. Den inre designas för att tåla låga temperaturer och bränslets vikt, medan denyttre designas för att innesluta allt under ett högt tryck, utan att väga speciellt mycket. Beräkningarna visar att idén är speciellt bra för tankar avsedda att innesluta flytande väte.

Modellbaserad ekoföljning i vätskefyllda tankar

This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

Nivådiagnos med sensorfusion : Utveckling av koncept för nivåmätning i lutande tankar 

Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.

Celltal som mått på mjölkens kvalitet med avseende på mjölkens sammansättning

Mastitis, an inflammation of the udder mainly caused by a bacterial infection, induces an increase in the somatic cell count (SCC) in milk and is consequently one of several factors affecting SCC in milk. In this literature review it is investigated whether SCC; on udder quarter, cow composite or bulk tank milk level, can be used as a quality marker with focus on milk composition in terms of the content of fat, lactose, total protein, casein and whey protein. According to this literature review the relation between SCC and milk composition is not reliable either on udder quarter, cow composite or bulk tank milk level. SCC was related to lactose, casein and whey protein on udder quarter level; lactose and whey protein on cow composite level and lactose on bulk tank milk level.

Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud

The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.

This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.

Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank

The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.

Släpslangspridning av gödsel, kan det löna sig? :

I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has. The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time. I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today. What is drag hose system? You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.

The insert shall be installed in the existing tank opening on diesel cars. The tank insert is designed for the Swedish company SverigeGrepen AB located in Vänge, just outside Uppsala. Their main product is a pitchfork that is ergonomically designed and durable.A pre-study were performed in which information relating to fuel caps, tank openings, petrol- and diesel nozzles were collected.

Undersökning av stereo och dynamiskt perspektiv i horisontell fish tank virtual reality

Ett par av de trick som används i virtual reality för att få 3D-världen att verka mer levande är stereoskopi och ett dynamiskt perspektiv med head tracking. Tidigare undersökningar har visat att head tracking har större effekt på 3D-upplevelsen än stereo [1], i alla fall när bilderna visas på en vanlig datorskärm. Den här undersökningen har försökt att ta reda på om samma sak gäller då den virtuella världen projiceras på en horisontell bordsskiva. Intressant nog går resultaten från det genomförda experimentet tvärt emot all teori. Tyvärr kan inga konkreta slutsatser dras eftersom alltför många felkällor har uppmärksammats, men studien öppnar ändå upp för framtida forskning..

Modellbygge av mekaniksystem och riktmotorer i stridsvagn 122

This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.

Att ta vara på solens fulla uppvärmningskapacitet

The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.
