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.

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.

This essay studies how advertisements in various anti-smoking campaigns can influence and persuade by using anti-logos as counter-arguments to the tobacco industry's logos. In contrast to tobacco advertising arguments such as freedom (logos), pleasure (pathos) and trademark (ethos) the anti-smoking campaigns create anti-logos arguments with various connotations such as repulsive pictures and sexual implications to influence groups of people not to start smoking or to quit smoking.Advertisement of tobacco does not exist nowadays due to legal restrictions in the western world; however several decades of myths created in the consumer consciousness still exist. Thus one can speak of a tobacco advertising ideology that exists and the various anti-smoking campaigns trying to change that ideology.The purpose of anti-smoking campaigns is to conduct a kategoria of myth that tobacco advertisement has created over the years. Anti smoking organizations do this by creating a new ideology to affect consumer?s attitude toward smoking and the tobacco myth with an anti-myth.

Detta arbete syftar till att undersöka vilket konventionellt ballistiskt skydd som krävs för att undvika penetration från finkalibriga projektiler, RSV-stridsdelar samt penetrerande stridsvagnsmina. Arbetet tar sitt ursprung i en handbok utgiven av FMV där stridsdelar som kan förekomma i Afghanistan behandlas. Handboken anger data och prestanda för dessa stridsdelar och det är därifrån arbetet tar uppgifter om genomslagsförmåga för stridsdelen. Skyddsprinciper och verkansprinciper för stridsdelar hämtas i huvudsak från rapporter utgivna av FOI samt från litteratur utgiven av FHS. Arbetets beskrivande delar inleds med en redogörelse för homogena ballistiska skyddsmaterial av metall samt keramer.

I detta examensarbete har en webbplats skapats för Falu Tank AB med hjälp av Jennifer Flemings utvecklingsmodell, även framtagning av en logotyp och grafisk profil med tillhörande manual har ingått i examensarbetet. Falu Tank AB utför nytillverkning, rekonditionering samt kontroll av petroleumtankar. De erbjuder också oljeavskiljare, pumpöar och dubbelmantlade tankar. Arbetet har bestått av en bakgrundsundersökning på Falu Tank AB, samt litteraturstudier i webbdesign och grafisk profilering, med en teoretisk fördjupning inom webbdesign. Bra webbdesign innebär i första hand att sidan är välstrukturerad, enhetlig, lättnavigerad, användarvänlig och att den har en bra harmoni.

This paper presents a study of the computer game ?Minesweeper?. The aim of the game is to search through a rectangular area of mined squares without hitting any mines. By using a strategy based on making every operation as safe as possible, series of the game have been simulated. The size of the playground is four times four squares.

In his master thesis, Johan Jutterström pursues an anti-aesthetic and ethic artistic process. He?s using mainly three different strategies; reasoning through text, composing for ensemble, and solo improvising on the saxophone. Through composing the piece for 12 musicians Trästolen, Jutterström tries to erase himself and his taste from the music. In that endeavor he looks to physics as a catalyst.

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.

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.

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.

Bullying is today a major problem in schools worldwide. Far too many children are forced to undergo bullying day in and day out without anyone seeing or doing something. My purpose with this study is to find out how four F-6 schools in a municipality south of Stockholm are describes their work to get zero tolerance for bullying at their school.My questions are:How does the four F-6 schools' anti-bullying group in a municipality south of Stockholm describes their work to have zero tolerance for bullying?What do the employees in the school anti-bullying groups consider that bullying is?Why do the employees in the school anti-bullying groups think bullying occurs?Who do the employees in the school anti-bullying groups think are bullies or are being bullied?To get my results I have done four interviews with those in charge of the school's anti-bullying group. My theory is based on standards, what is acceptable behavior and normative theory, hypotheses, what is right and wrong as well as desirable or undesirable behavior.

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.

Fotorealistiska 3d-bilder används idag inom ett brett spektrum av branscher. Framställningen av denna typ av grafik kräver ofta väldigt mycket datorkraft. Vid rendering med renderingsmotorer som använder sig av raytracing algoritmer är aliasing ett medfött problem. Lösningen heter anti-aliasing som arbetar för att undvika aliasing artefakter som jagged edges eller Moiré-effekter med mera. En del av anti-aliasingprocessen är supersampling som ofta kräver mycket datorkraft.
