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. .

Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Title: Valuing Real Estate FCFE and interest coverage under macroeconomic uncertainty with scenario analysisAuthors: Marcus Ewerstrand, Jakob MattssonAdvisor: Gert SandahlBackground and problem: After the collapse in the Swedish economy in the beginning of the 1990-ties, the company Secerum was launched. Securums objective was to handle unsecured credits from Nordbanken by transferring a large portfolio of properties and to setup a number of companies who would be in charge for the prospects of these assets. One company that was established during this remarkable period was Castellum, in the year of 1994. After a successful process of raising capital to its development of corporate strategies and formation of several affiliated companies which operates locally, Castellum was publish on the Stockholm stock exchange 1997/1998. Now, thirteen years later after its establishment, the credit crunch in the US.

This thesis aims to investigate the information effects of fair value accounting in Nordic real estate companies. As a consequence of the mandatory IFRS adoption in the European Union in 2005, listed Nordic companies are allowed to recognize investment property at fair value in accordance with IAS 40. Theory suggests that fair value accounting should lower information asymmetry. Therefore, this study aims to examine correlation between fair value accounting of investment property and information asymmetry on the stock market. To investigate this, we use bid-ask spread as a proxy for information asymmetry and examine Nordic real estate companies before and after the implementation of IFRS.

 We have chosen to write our thesis within a transport company. The work was carried out at DHL activities in Uppsala. DHL is one of the leading transport companies worldwide. Our interest lies in more efficient and advanced transportation and terminals, as globalization and new trends require effective solutions.The aim of our work is to explain the need for information technology applications in road haulage and associated terminal operations. Furthermore, we analyses terminal and applied information technology.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

As most developed countries Norway has an ageing population meaning that the number of pensioners is predicted to grow rapidly over the coming years. As a consequence the Norwegian pension system will not be able to provide for these future pensioners. Meanwhile, a rising number of early retirees and disability pension claimants is diminishing the real retirement age. Also the individual pension amount is growing while the pension system itself reaches maturity. In short, major reforms are needed in the Norwegian pension system.

Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.

The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

With this study we aim to learn more about the relationship between digitalization and the swedish church. We have interviewed two priests and two other persons ? one who got married about five years ago, and one who, at the time of writing, is getting married in a few weeks. In addition to the interviews we found some earlier research that were relevant to us, which we read and compared to the empirics we got from the interviews. In our study we have taken qualitative research into practice since we want our interviewees to really share their points of view on the organisation?s usage of digital media.

This essay deals with the question of lines of development within the politics in the rural municipality of Nyed 1950-1962. The aim is to explore how local politics and policies were handled from two perspectives. Firstly the issue of conflict and consensus or majority rule and consensus. Here Arend Lijphard's theory of majority and consensus provides a theoretical base for the essay. Secondly the aim is to explore the actions of the local politicians with regards to leisure time policies to find out whether or not they ideologically belonged to the concept of ?folkhemmets kommun? by Ulla Ekström von Essen.The source material for this essay has been the minutes from the two major bodies of local politics in Nyed, kommunalfullmäktige and kommunalnämnden.

Denna studie har haft som syfte att belysa ledarskapet i grundskolan avseende den studie- och yrkesorienterande verksamheten samt förhållandet mellan ledarskap, personalens engagemang och verksamhetens resultat. Avsikten har bland annat varit att synliggöra om skolorna har ett reellt ledarskap avseende verksamheten eller inte. Bedömningsgrunderna för ett reellt ledarskap har inspirerats av den transformativa ledarskapsteorin. Studien baseras på enkätsvar från 107 yrkesverksamma studie- och yrkesvägledare i Stockholms, Skånes och Västerbottens län. Resultatet visar att den stora majoriteten skolor saknar ett reellt ledarskap avseende verksamhetsområdet samtidigt som flera studie- och yrkesvägledare säger sig vilja inta en ledande funktion för detta.

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.
