Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigated in the report. .

The purpose of this paper is to study what the press in Sweden wrote about counterfeiting from 1944 to 1950. By studying how the newspapers wrote about the crime of counterfeiting, the paper aims to give a glimpse of how counterfeiters worked and got their notes in circulation. The analysis is based on a theoretical perspective of a "we" and "they" in which Sweden is compared to the opposite abroad. The paper examines how the security of Swedish banknotes is discussed in Swedish news articles and how they describe counterfeiters and passers. The paper examines forty one newspaper clippings from the period 1944-1950 from twenty five different newspapers from different parts of the country.

?Street prostitution, why there?? is about how the physical planning and physical environment affect the localization of street prostitution in Gothenburg. The aim is to increase the understanding of how social security is linked to man's immediate environment and are influenced by the physical environment. Important concepts that are explained in the paper are social security, prostitution, and physical planning.This study deals with theories about the factors that may influence why criminality localized to a specific area, such as legislation, urban planning and community. The study conducted interviews with the Gothenburg Police, Västra Götaland County Administrative Board, Gothenburg City, Stadsmissionen and Mikamottagningen.

This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

 The english name of this essay is ?One man among many women?. This essay takes its starting point in the situation today with few male teachers in the earlier years of elementary school. I have decided to look at the small group of males that actually started the education to become teachers and why they did it when the profession as teacher today is low-paid, low status and is a profession with a large dominance of female teachers. I have chosen to write about this because of the importance for the children to meet both men and women as teachers in the early schoolyears.

ABSTRACT:Uppsatsens syfte är att studera manlighetskonstruktionen i två pjäser av Eugene O´Neill: The Iceman Cometh och Long Day´s Journey Into Night. Detta genom att undersöka vilka mottyper till den normativa manligheten som förekommer i pjäsen, i vilken grad männen i pjäserna har behov av en homosocial arena för att få sin manlighet bekräftad och om kvinnan har någon roll att spela i maskulinitetsskapandet.I The Iceman Cometh är den tydligaste mottypen alkoholisten. Denne är en man som gett upp i kampen om att uppnå statusen av en ?self-made man?. Exempel på en konkurrerande manlighetsbild finns i de karaktärer som har ett förflutet inom den amerikanska anarkiströrelsen.

The purpose with this study is to examine how the media coverage of the train accidentoutside Kimstad, on the night of September 12th 2010, was framed in one local (Norrköpingsnyheter) and one national newspaper (Expressen) and how the coverage of the accident wasdifferent in the local newspaper compared to the national newspaper.The material is 12 articles within a fixed time limit which is from September 13th toSeptember 15th. The material consists of six articles from each newspaper.The method we use a qualitative text analysis with its basis in medialogic, news value andframing theory.In the essay?s analysis we show a synthesis of both newspapers coverage of the train accidentoutside Kimstad and how they stand in relation to the theory of news value and we end with aterminative comment about the results.The conclusion shows that the coverage of the event was different in many ways. Expressenuses a more dramatic framing and a more sensational language which describes the eventmore badly than it was. NT uses a more informative and objective information which almosttrifles the event but which informs about relevant information for the locals.

I uppsatsen analyseras representationen av romsk etnicitet i de amerikanska filmerna Dracula (1931, Browning), Thinner (1996, Holland), Drag Me To Hell (2009, Raimi), Draculas Son (1943, Siodmak) och Varulven (1941, Waggner) samt afroamerikansk etnicitet i Night of the Living Dead (1968, Romero), De Fördömdas Drottning (2002, Rymer), Draculas Son och Svart Mystik (1943, Tourneur). Syftet med uppsatsen är att blottlägga representationen av icke-amerikanska etniciteter genom analys av handling och bildspråk, samt jämföra framställningen med respresentationen av de amerikanska karaktärerna i valda filmer. Målet var att undersöka och kritiskt granska stereotypa bilder. Metoden vilar på en personlig, hermeneutisk tolkning av forskningsobjekten där den egna upplevelsen av filmerna står i centrum. Jag har även använt mig av intersektionalitet för att täcka alla identitetsskapande aspekter så som genus, etnicitet, religion, sexualitet med mera.

The purpose of this thesis is to explain why states obtain nuclear weapons and the role variousactors and interests play in the making of states´ nuclear policies. The main questions are asfollows: (1) What big theories exist concerning states obtaining nuclear weapon and nucleararmament in International Relations and what relevance do they have of the post cold-war period?,(2) What is the meaning of the perspective of the Military-Industrial Complex (MIC)?, and (3)Arethere empirical studies which supports the existence of a MIC in the United States?The focus lies on actors and driving forces that are internal to states and it is also important toinvestigate if the theories have relevance for the post 9/11-era. The study uses the method ofqualitative literature-study with some quantitative segments. It is claimed that states might beinterested in justifying their behaviour in a morally appealing way and that real reasons may behidden.

The purpose of this master?s thesis is to investigate children?s access to specific children?s activities at Swedish public libraries 2005. The thesis is based on literature studies and qualitative interviews with children?s librarians, library directors and local politicians at two demographically different libraries in Gothenburg.The sub questions are: What measures exist to promote children?s access to public libraries and children?s activities when it comes to: law and other political statements: different efforts on the state level and different efforts on the municipal level in the direct activity with children at public libraries? What driving forces and needs justify activities for children at public libraries? How will the responsible persons judge that the efforts are sufficient? The result of the study shows that children?s access to library activity has increased in the last couple of years due to reorganization, economic savings with closing down of library affiliates and because libraries have given priority to other things, like IT and new media. Children?s librarians have got new assignments and less time for children?s activity.The conclusion of our investigation is that children?s librarians are ambitious in their work, but unfortunately don?t give children?s library activity adequate resources.

The purpose of this Masters thesis is to investigate the reasons for public libraries to have story-time today and also the reasons for story-time at the public library historically in Sweden. Why is the phenomenon of story-time still existing at public libraries today? The study is based on a questionnaire that was sent to childrens librarians in the Västra Götaland region. The material collected in this questionnaire was put together and resulted in six different categories showing the libraries purposes and thoughts of their story-time activities. The categories were: cultural heritage/tradition, joy of reading, language and imagination, library visits, storytelling and mutual experience.

Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.

Today it is common to have adult horses stabled for most of the day. This limits the horses? ability to perform some of their natural behaviors such as foraging and movement. The purpose of this review was to compare the feral horses? diurnal rhythm and time budget with stabled horses.
