The aim of this project was to quantify the total sleep time in modern dairy cows during24-hour periods and to investigate whether the total amount of sleep as well as timespent in different sleep stages varies between the dry period, early- and peak lactation.The distribution of sleep time between night and day was also examined. Furthermore,correlations between sleep and lying time, fluctuations in body temperature and heartbeat were included in the aim. Eight dairy cows of the Swedish Red breed were used inthis study, which was carried out between June and September 2010. In order toquantify sleep non-invasive electrophysiological recordings were performed.Simultaneously with collecting sleep data, body position and body temperature werealso recorded. No heart rate data was obtained due to difficulties of maintainingelectrodes for heart beat measurements attached to the skin.

In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

This study was made to compare construction companies for gardens way to work with up following, with purpose to see if there was an efficient and not resource demanded system which gave much value. To achieve the purpose a case study was made. The delimitation for the case study was only to compare the work with up following on individual project. The delimitation on the companies in the study was from ten to sixty employees. That because to reach companies were it´s not the same person how calculates on tenders and than perform the projects. The study was delimitated to the west side of Skåne. T o be able to compare the companies and to find trends, an interviewguide was made and was used during the interviews with the companies.

This study is focused on some individuals' experience of the concept of culture in their everyday life. Some questions about culture were asked to some persons living in a small village in the isle of Gotland and some persons in the capital of Sweden, Stockholm, in the autumn in 2007 in a field study.The study showed that peopele tend to shape their own life world in the continuous activity in their near surroundings, in the garden and in reading literature and listening to music. There were some differences in the life world depending on where they lived,  in the country side or in town. Urban life has more offers as to popera and theatres but negatively more violence and stress.A study of literature on the ethnological concept of culture is included. The answers of the individuals also led to different topics such as nostalgia, mind, fear, feelings, body and soul which were enlightened by scientist from the respective fields..

In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

ABSTRACT The main purpose of IT security policies is to protect companies against intrusion and unwanted spread of information. Statistics show that IT related crimes tend to increase and because of that it is important, from the company?s side of view, to be well prepared. The IT security policy is an important part of that preparation. A lot of the crimes related to IT can be deduced indirectly to employees at the companies where the crime takes place.

The controversial phenomenon of ?seeker-oriented? megachurches are currently transforming the American religious landscape. These churches, some housing up to 30,000 worshippers every week, are targeting religious seekers as their primary objective. Their success in attracting and converting those who usually wouldn?t even think of attending church can in large parts be explained by changes in liturgy, the removal of visible theological discussion and use of shopping mall styled buildings, designed to make the religious seeker feel like home.

Background: One of the main concerns related to medical therapy is non-compliance to drugs. More than half of all patients do not comply with prescribed medication. Non-compliance to drug therapy leads to unnecessary suffering for the patient and there are no easy solutions to the problem. In order to create understanding for the individual patient it is important that medical staffs are enlightened on the existing problems concerning this matter. Purpose: To describe factors that effect compliance to drug prescription.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

Cloud computing has become a very publicized and popular concept in recent years, both in business literature and research, where data ownership is the security aspect which has usually been ranked the highest of the disadvantages that can be identified with cloud services. Today there is a lack of research on information ownership from an informatics perspective, as it is most often discussed from a legal perspective.In our study we interviewed six different companies that use cloud services, on which attitudes and reasoning they had on their information ownership. We compared these attitudes with the attitudes we identified in business literature and research on the subject. In business literature we found four recurring themes which were very clear about how a company should govern information ownership.Overall the results of our interviews showed that there is widespread ignorance at the companies on how information ownership in the cloud is regulated between the company and the cloud provider. All companies expressed that they had not experienced any change in ownership when they placed their data in the cloud, and they expressed no major concerns about how the ownership was handled.

Intervjuer har genomförts med personer som är insatta och kunniga i ämnet och därför kunnat bidra med en sammanfattad bild av vilka initiativ och ambitioner som finns i dagsläget. Studiens resultat visar att Big Data kan bidra med en mängd möjligheter till förbättrad sjukvård i Sverige. Resultatet visar på att möjligheten med att samla all information i en gemensam kärna, bidrar till bland annat förbättrad forskning, en förbättrad relation mellan vårdgivare och patienter, möjlighet att kunna utföra prediktiva analyser samt underlättar arbetet med diagnostisering av sjukdomar.

Digitizing objects and environments from real world has become an important part of creating realistic computer graphics. Through the use of structured lighting and laser time-of-flight measurements the capturing of geometric models is now a common process. The result are visualizations where viewers gain new possibilities for both visual and intellectual experiences. This thesis presents the reconstruction of the Parthenon temple and its environment in Athens, Greece by using a 3D laser-scanning technique. In order to reconstruct a realistic model using 3D scanning techniques there are various phases in which the acquired datasets have to be processed.
