Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

This bachelor thesis aims to analyse the effects of changes in management control systems following acquisitions, and deduce whether or not these effects are in line with the acquiring firm's objectives of the acquisition. Through a case study of technician consultant firm Energo, acquired in 2010 by ÅF, the study assumes the perspective of the acquired firm. Data has been collected through in-depth interviews at Energo and ÅF and complemented by internal documents to enrich and validate specific facts and statements. Data was then arranged and analysed through Otley and Fierriera's (2009) framework Performance Management Systems to understand how management control systems were constituted before the acquisition, what changes were made following the acquisition, how this process was accomplished and how it was experienced, in order to come to conclusions about the effects of these changes. The study concludes that the changes in Energo's management control system following the integration with ÅF, had significant effects on the outcome of the acquisition, primarily as it led to a high rate of Energo's employees resigning.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

Purpose: To examine the governance mechanisms and the competence PE-firms adds to theirholding companies through an active ownership in order to create growth.Methodology: A qualitative study with interviews as its main source of data.Theoretical perspectives: Corporate governance and relevant theories within that subjectsuch as agent theory, board of directors and management. Previous research within the subjectwill also be presented.Empirical foundation: The empirical foundation consists of three conducted interviews anddata collected from the chosen PE-firms as well as six different holding companies.Conclusions: The governance mechanisms used in the PE-firms we have chosen are stronglyrelated to both theories within corporate governance as well as previous research on thesubject. The governance mechanisms being used are an explicit owners agenda and strategy, athorough acquisition process, usage of external competence, active ownership through theboard of directors and the insertion of incentive systems..

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

The aim of this study was to investigate how seasonal variations affect the quality of logging residues. The study was hosted by VIDA Energy. Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk transportation of logging residues. In these systems the handling of the logging residues are carried out in the same manner up to the landings. Moisture content at the time of chipping is the primary quality parameter. Fine fractions of logging residues are strongly dependent on moisture content in storage.

This thesis examines the approach for implementing strategy that has been applied by the study object, Svenska Spel. The specific approach originates from the theories of Elliot Jaques, whose key proposal is that individuals have different capability of carrying out tasks over different time-spans. The main purpose of the study is to analyze how the approach has influenced the management control systems in use, in order to ensure that the strategy is successfully implemented on corporate as well as operational level. Twenty in debt interviews conducted with employees, representing a vertical cross section throughout the organization, are the main source of the study?s empirical foundation.

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation. The possibility to protect oneself against attacks from the outside becomes increasingly difficult.

Based on last years events that have taken place, events on the school Lundbergs and the police values of work, has the meaning of having a set of values been questioned. This study aimed to investigate and answer the fundamental values based on the common value basis for the government employees within an organization and how it perceived by employees. The new institutional theory was the framework for this qualitative study conducted with semi-structured interviews. Respondents were employees within the organization. Ethnographic qualitative methodology was the basis for our methodology and we used a thematic model of theme interpretation, communication and knowledge in our analysis.
