Studier av utseendet på askan i sodapannor med hjälp av bildanalys

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

De spelberoendes barn : En kvalitativ studie av nio personers upplevelser av att vara barn till en spelberoende

The aim of this essay was to examine children's experiences of having a pathological gambler as a parent, which consequences this led to socially, economically and emotionally, if those children got any help and in that case where and what kind of help.Central questions asked where:* In what way did the child experience consequences from the parent's gambling?* How did the child experience the gambling parent during the gambling period?* In what way did the gambling affect the relationship between the parent and the child?* How did the parent's gambling affect the child socially, emotionally and economically?* How did the child handle this?* What help did the child itself think it required?* Where did the child got help?This is a qualitative study of nine today adult persons that grown up with a pathological gambler as a parent. The method is qualitative semi structured interviews.The results of the study are that all of them experienced large consequences socially, emotionally and economically. The consequences varied depending on the total situation in the family. The result shows that all of them have got coping abilities and they have applied more to emotion-focused forms of coping than to problem-focused coping..

Bildåtervinning för alla: Att tillgängliggöra bildsamlingar för en bred och ickespecificerad användargrupp.

This essay is a survey of thirteen user studies performed in the field of image retrieval. The purpose is to try to distinguish principles that should be kept in mind when wanting to make image databases available for a wide and varied group of users. The essay tries to answer two questions, namely: Are there any results in accordance among the different studies? What in the user studies should be considered when it comes to how content description, interface and functions for searching can be designed when creating systems for image retrieval? Each study is first reviewed on its own, and then a comparative analysis of all the studies is carried out. Derived from the result of this analysis, the conclusion is presented in the form of a row of suggestions to which aspects are to be suitably included in the design of image databases.

DU#kulturskolan : En kvantitativ studie om hur elever ser på sitt engagemang då de musicerar och undervisas på kulturskolan.

The Sand Catcher                                                       The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.

Bilderna i klassrummet : ur ett genusperspektiv

The purpose of this essay is to examine what kind of pictures the children encounter everyday in their classroom. Furthermore, the idea was to immerse myself in how girls and boys are portrayed in these pictures from a gender perspective. Three question were set, to enable this study: What kind of pictures will second grade pupils encounter in their classroom, in a city school and in a rural school?How many girls and boys are illustrated in these pictures?How are girls and boys portrayed in these pictures?The examination was done by a field study of two classrooms, where all the pictures on the walls were documented using a digital camera. The collected material were examined, using both a quantitative analysis and a qualitative ditto.

Produktionsutveckling av bastuaggregatsavdelning

To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an  efficient and ergonomic way.After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically.

Män i tights och kvinnor i byxor : En kritisk undersökning av hur film kan användas i historieundervisningen för att lära eleverna studera förändringar i genus och hur dessa kan relateras till sin samtidskontext

Film is a tool frequently used by teachers, but it is often limited to showing students how historical time periods looked like, or as a way for students to search for historical inaccuracies. The aim of this essay is to study whether it is possible to use two films based on the legend of Robin Hood as a way to teach students how to contextualize gender history. Through the use of film analysis and gender analysis of two different versions of Robin Hood, The adventures of Robin Hood and Robin Hood: Prince of thieves were analyzed. The study has shown that it is indeed possible to use film as a source material for the study of gender history, and that film can tell us a lot about the contemporary view of gender, masculinity and femininity. The didactical analysis concluded that there was no theoretical objection of using film as a source material; however, there are some things that a teacher should be aware of. Although film may be a good way to create a varied study environment and benefit students with reading- and writing disabilities, there is a risk that time-constraints and lack of knowledge of film and its methodology on, behalf of both teachers and students, may make it hard to implement.

Flöden och processer på Fristadstorget

This thesis is about Fristadstorget in the city of Eskilstuna and how the square flow together with the user orientation could be improved. This work focuses on how public spaces best satisfy users through architecture, cognition and information interpretation. I've looked at people's movement patterns in Fristadstorget, with the help of observation from strategic locations. While I also integrated the city?s surrounding and taking in information from already existing buildings around the square.

Afasi-vänlig information : inför funktionell undersökning av språk med magnetresonanstomografi (fMRI)

Functional Magnetic Resonance Imaging, fMRI, can be used for analyzing brain activity in subjects performing language tasks. The purpose of this study was to develop aphasia-friendly information adjusted to aphasic subjects participating in fMRI studies. The objectives were to investigate if adjusted information was important for the ability to perform language tasks and if the information could be used for different types of aphasia.Sixteen aphasic subjects participated in the study, six of these underwent fMRI. The participants varied in grade and type of aphasia. They had Swedish as their native language and were aged between 26 and 89, mean 57.

Lokalt omhändertagande av dagvatten i Västerås - Möjligheter till ökad användning i befintliga innerstadsområden : Local disposal of storm water i Västerås - possibilities for increased use in downtown areas

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Barns boende : socialsekreterares konstruktion av principen om barnets bästa i förhållande till materiell standard

The purpose of this study was to examine how a selection of social welfare officers based on the principle of the best interest of the child construct a minimum level of the material standard in a home. Another purpose was to examine whether different units with varying socioeconomic prerequisites in the municipality of Stockholm construct this level differently.The method used in this study was Sociology of Law and two focus groups were used for the gathering of the data. A social constructive theory, a class perspective using concepts of Bourdieu and a perspective of law were used to analyse the material of data.The results showed that the courses of action varied from enactment and the policies of the municipality of Stockholm, unspecified theories of the development of children, the conception of what is normal and what children needs, the context in which they work, the development of the society and what they estimate that children needs when attending school. The results also showed a difference between the two units concerning the minimum level of the material standard in a home.

This Masters thesis concerns feature film services in Swedish public libraries. We have investigated the opinion of eight librarians concerning values and criteria for selection as regards film. The theory chosen comes from varied disciplines, for example sociology, adapted to our subject. The most important theories are Antonio Gramscis idea of hegemony, Herbert J. Gans concept of taste cultures and Carl Gustav Johannsens discussion about quality.

Läslust hos elever med svenska som andraspråk. En fenomenografisk studie

The purpose of this master?s thesis is to examine how pupils with Swedish as a second language and school librarians perceive the concept of pleasure of reading and the feeling of being a part of society. Our research is based on qualitative interviews with eight students in grades 6-9 and from two different schools. We have also interviewed two school librarians in these two libraries. As a method of analysis, we used phenomenography because it is the informants' perceptions of the phenomenon of pleasure of reading that we investigate.
