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. .

Nowdays an efficient production is critical to achieve for companies competing on the market for steel cutting tools. One of such companies is Halmstad based Tooling Support Halmstad AB that manufactures threading-taps, threading-dies and parting off tools, towards a centralized warehouse in Schiedam, Holland. The large amount of different products, approximately 2500 is a big contributor to the problem along with a new order system that creates a demand of low setup times. Previously the company was forwarded orders through quarter based prognoses which enabled planning of the production over a longer time span. Currently the newer order system ZENIT is in use and the company thereby gets their orders weekly.

I planeringssammanhang är det vanligt att tala om en attraktiv stad, men begreppet är svårdefinierat. Dels därför att det är starkt kopplat till individens egna värderingar, men också därför att begreppet består av många faktorer. Det är därför praktiskt omöjligt att utforma en attraktiv stad om inte begreppet attraktiv stad definieras. Det finns många teoretiker som forskat inom området, genom olika tidsepoker och med olika infallsvinklar. Trots den allomfattande forskningen finns det idag ingen enskild teori eller definition på vad som utgör en attraktiv stad. Examensarbetet har lett fram till en undersökning av begreppet attraktiv stad, som sedermera lett fram till olika faktorer och beståndsdelar som bygger upp definitionen attraktiv stad.

Begreppet hållbar utveckling har växt fram kring orsaker och lösningar för globala försörjnings- och deponeringskriser. Begreppet är mycket brett och diskuteras runt om i världen. Diskussionen om hur samhället ska uppnå en hållbar utveckling har påverkat fysisk planering och trafikplanering. Grunden till en hållbar utveckling ligger i en samordnad och miljöanpassad bebyggele- och trafikplanering. Det är bland annat viktigt att det finns förutsättningar för en effektiv och miljöanpassad kollektivtrafik och ett effektivt gång- och cykeltrafiknät.

The work with this report has been focused on developing a methodology model for control at purchase. The methodology model covers parts classification, dispatching systems, batch shaping and more. The aim with the methodology model is that it will be used as an aid for a cost effective material planning to increase the value for customer.The work covers also a description of the present situation and the purchase process at Company X. Six parts have been applied, two from each class (A, B and C), in the methodology/model. The parts that have been applied are included in the flow between Company X and their supplier Company Y.Data have been collected trough literature studies, interviews and the company?s business system.

The ongoing change that characterizes the landscape as a result of the development of the society as a wholeis the basis for this thesis. Even though the Scanian landscape still is dominated by arable land, other valuessuch as biological diversity, cultural heritage and economical aspects, has all been ascribed the landscape asmore and more important factors and in some respects, compete with the farming industry about the right tothe landscape. Our demand of more and more space, will of course also affect the landscape. Huge amountof land are used to build external malls and single-family houses, which gives rise to an increasing need foran extended transport system that also is land consuming.It all comes down to: how the municipalities deal with non built areas - the green structure. Do themunicipalities have separate programs describing their vision and objectives concerning the green structure?Literature studies, an inventory made of the municipality programs in the west and south west of Scaniaand interviews with employees at the municipalities clarifies the use of the green structure concept, both intheory and in practice.The green structure concept seems to be derived from the environmental debate.

The aim of our study is to gain increased knowledge and understanding of how young people who has been sentenced to closed institutional care experience their own possibility to participate and influence the transition and aftercare, and which, if any, importance they believe this has for their readjustment to society. The study is based on a qualitative method. The data consist of interviews with four young persons, of which three, at the time for our interviews, where in the transitionphase, and one had left the institution a few years ago. The study?s theoretical framework is based on Erving Goffmans theory about stigma and the empowerment theory.

The purpose of this thesis is to investigate and analyze existing law concerning joint owner-ship in agriculture and forestry businesses. Joint ownership often arises through a succes-sion of ownership, therefore we will go through the most useful methods.Even if the owners of agriculture and forestry businesses are getting older, the numbers of succession of ownerships are still low. A succession of ownership is important to plan and its time is demanding. Often it takes three to five years for the completion of a succession of ownership. Therefore, owners must start their planning in time and think about what is to come of their business.

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 annual cost of home care services of transport in Falun/Borlänge, is now at 31 million kronor. It is clear from previous research that it is possible to reduce these costs through a restructuring of the existing home-help service. The restructuring aims to have a higher proportion of older people, who are in need of care, to live in special accommodation, in order to reduce transport costs. Therefore there is a need for systems that allow home-help service to plan their operations in such a way that transport is working as efficiently as possible. Through better planning, there are profits to be done.

This thesis focuses on the driver?s experience of the road and its surroundings. ?The view from the road? takes place every day and a high-quality ?road experience? is therefore a question of importance. Since cars made their breakthrough in the 1920-30, the approach to ?the driver experience? has varied notably.

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.
