The purpose of this study is to examine whether there is any connection between working hours, desired working hours and the worker ?s health. The study also aims to investigate if there are any differences over time. Earlier studies have shown that individuals need a balance in their life between worked hours and free time. This balance seems to be important for employees if they want to lead and remain a healthy lifestyle.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

In modern dairy production, the newborn calf generally is separated from its mother and put in a single pen for some time before it is introduced to group housing. Group housing is becoming more and more common because it saves the farmer a lot of valuable time. Even thought group housing has a lot of benefits it is often associated with a higher morbidity and mortality in the young calves. Therefore, knowing the optimal way to use the group pen lies in many farmers? interests and the importance of different factors such as the optimal age of introduction is important to evaluate. The aim of this study was to investigate the effect of age at introduction to group housing on the health of the calves in the group pen.

This thesis processes the work of developing CPU code and GPU code for Thomas Kaijsers algorithm for calculating the kantorovich distance and the performance between the two is compared. Initially there is a rundown of the algorithm which calculates the kantorovich distance between two images. Thereafter we go through the CPU implementation followed by GPGPU written in CUDA. Then the results are presented. Lastly, an analysis about the results and a discussion with possible improvements is presented for possible future applications..

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Life is for us humans a social life. We are constantly in different social communities with various purposes. Throughout life we are part of different groups, for better or worse. The basic social communities, in our society, are the groups we live, work, learn and grow in. This essay deals with the groups children develop and learn in, in school and leisure time center.

During the 1920?s the town of Bollnäs had the ambition to expand. The expansion included a merger with Björkhamre and the colonization of unused areas, e.g. the area around Onbacken. The archaeologist Gustaf Hallström came to Bollnäs to investigate an ancient tomb located on Onbacken.

This thesis deals with information practices of first time parents. The term information practice covers topics ranging from the information a parent need and use, the information they actively seek for through to information attained through browsing, monitoring or simply being aware. Four problem areas have been formulated. What information do first time parents need? How do they get hold of information and how do they use it? What factors decide what sources they use? How do the first time parents validate the information they get? The following theoretical framework have been used; Marcia J Bates? model of information practice and Reijo Savolainen?s Mastery of Life theory.

There is considerable variation between stallions in semen quality and fertility due to the fact that selection of stallions for breeding is not based on fertility or semen quality but on performance. The increasing use of cooled semen for artificial insemination has resulted in decreasing pregnancy rates. Therefore the equine breeding industry needs new methods for evaluation and development of sperm quality and fertility. This study is a part of such a project and is performed by SLU in cooperation with Flyinge AB. Ten stallions at the Flyinge National Stud were used in the study and three ejaculates were collected from each stallion.

In 1996 a hunting test for British gun dogs was started in Sweden, based on a similar one al-ready in place in Norway. The aim of the new test was to describe the hunting ability of the dog and to use the results as a basis for selection. However, up to now, no genetic study of these data has been done. Therefore the aim of this study was to estimate genetic parameters for the traits measured in the hunting test and to investigate whether the traits can summarized into fewer overall measures. Data from trails of British gundogs between 1996 and 2005 in Sweden were used to estimate genetic parameters and environmental effects in hunting performance. British gundogs consist of five different breeds: Pointer, English setter (ES), Gordon setter (GS), Irish red setter (Irl S) and Irish red and white setter.

The construction process which is used today while constructing residential buildings has for along time remained unchanged. Unfortunately the development process has gone away frombecoming industrialized and instead most of the work is done at the construction site. In thisrespect this is a worse alternative because the project outcome will be more expensive and theconstruction time will be longer. Skanska?s vision is to have a process which is more like the oneused in small residential buildings which is fully industrialized.The constructing process for residential building involves more parties and therefore it becomesmore complicated.

The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.

ABSTRACTJuvenile is a phenomena that more or less always has been around in our societies. From a society perspective, a crime is committed if actions that the legislative power of state consider as unacceptable or actions that are punishable. There is no particular explanation to why certain people become criminal; crime can be caused by many different factors at the same time. There are several types of justice. In this essay, it is reparative justice for shoplifting in force, that will be illustrated.The purpose of this essay is to investigate how the shopkeepers experience incidents such as shoplifting or theft in their stores, and how they will react and act if they will be exposed by circumstances like that.
