3109 Uppsatser om Automatic milking systems - Sida 12 av 208

Arbetsmiljö i stora mjölkkobesättningar :

Earlier studies have shown that musculoskeletal disorders among animal keepers are more frequent than in other occupations. Most of the farms have expanded and the farmers who used to work alone have suddenly become a work manager with several employers. There are only a few studies made on the work environment in dairy farms. Our study is based on a questionnaire and is a part of a project called large dairy herds. The study is based on data from the persons who milk most of the time. The questions they had to answer were about the work environment, musculoskeletal disorders and the psychosocial environment. The results of the survey are presented in diagrams and figures. It was common that the dairy producer themselves answered the questionnaire.

Environment simulation of track-based systems

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

Representativa testnät försvenska eldistributionsnät

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Automatiskt avvägningssystem för obemannad undervattensfarkost

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

Ekonomistyrningens påverkan på MRP-implementering: en fallstudie av ASSA AB

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

Homosexualitet i tre klassifikationssystem under tre decennier: Ett queerteoretiskt perspektiv på SAB, UDK och DDC.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

Att skilja äpplen från päron : en studie om belöningssystem

Companies today need to be more focused than ever on having an active Human Resource Management culture. This is not only because of the companies? concern for their staffs wellbeing, but for the companies? effectiveness in the long run. The reward systems which many corporations use today, to both keep their employees and attract new ones, is a well researched subject by scholars as well as journalists. Earlier research has suggested that it is important to implement an active Human Resource Strategy.

Automatisk benplockare för lax : En vidareutveckling av befintlig prototyp

This thesis describes a further development of an existing prototype named Automatic pin bone remover. The further development was requested from the Swedish consulting firm ATM AB. The request of automatic pin bone removers is high and has the potential to be a worldwide leading product.The goal with the thesis work is to further develop an existing prototype. In order to achieve the goal a pre-study of the prototype had to be made in order to define a customer demand specification. The thesis work is then continued by a function analysis which differs from a conservative one.

Webbens klassifikationssystem. En komparativ studie

This thesis deals with subject-based hierarchical search-services on the World Wide Web. The purpose is to investigate how systems of this kind facilitate information retrieval through subject-based information seeking. Its starting point is taken from the study of texts and qualitative analyses of search-services on the World Wide Web. Important aspects and features of the Internet and the World Wide Web are explained as well. Three systems are examined: Mölndals Stadsbiblioteks Länkkatalog, Svesök, and Alta Vista.

Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

XML som informationsbärare för EDI

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.

Media and the priming of stereotypes: Direct effect of news articles racial stereotypes on individuals judgements of people of foreign extraction.

The present research examined both automatic and controlled processes in newpapers ability of priming racial stereotypes via the portrayals of people of foreign extraction. The automatic process were examined through articles which; a) involved an illegal act or b) the act was not illegal but morally questionable. Swedish-born subject?s explicit opinions against foreign people were also measured through ?The Modern Racial Prejudice Scale?. In the experiment participants read four different articles which included; Swedish person/noncrime, foreign person/noncrime, Swedish person/crime and foreign person/crime.

Deriving ECA-rules from timed-automata specifications.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Alternativ för värme- och kylaförsörjning i planerade kontorsbyggnader på Arlanda

This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.

Hantering av informationssystem

Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.
