The purpose with this study was to investigate how the behaviour and physiological parameters differ between high ranked and low ranked cows, and between cows in an Automatic milking system verses conventional milking parlour. The study was carried out at the Kungsängen research Centre, Department of animal nutrition an management, Swedish University of Agriculture Sciences, Uppsala. Twelve cows, the six highest and the six lowest in social rank were selected from the Automatic milking system for the experiment. Ten cows, the five highest and five lowest in social rank were selected from the conventional system. Blood samples were taken during milking and resting.

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an Automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the Automatic hammer.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop Automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of Automatic headlight level control on Scania vehicles..

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were Automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with Automatic cable driven scrapers on solid alleys, Automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

Oxygen consumption and carbon dioxide production are usual measurements within the sports and training physiology. The same measurements are also common when it comes to establish the amount of energy that is used during work and to establish the intensity of work. The volume of oxygen that is consumed contra the volume of carbon dioxide that is produced can be used to calculate the metabolic rate within the human body. This calculation shows the percent relationship between carbohydrates and fat in the metabolism. The first accurate method to measure the breathing gases for use in metabolic calculation was established in the early twenty century when the Douglas bag method was introduced.

Mek Stans 07 is a machine developed for Tetra Pak in Lund as a 10p candidate theses project at Halmstad University. The commission behind the project involved development of a machine that punches holes in packages for the inspection division at Tetra Pak. The task for the machine was to facilitate the process of making openings for testing in the company?s other equipment. Researches on different methods of cutting, types of automatization and possible designs were made. To implement the project a design and construction from the base where chosen.

This thesis is basically a design project aimed to find a safe and reliable Automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The Automatic protection device assist the operator in situations when loading or going in and out of the danger zone.

An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to Automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.

If you have access to wood, a wood burning boiler is a cheap way to heat your home, but it is certainly not the most convenient option. Wood requires many operations and management, which takes time. One way to reduce this workload is to have a modern boiler with Automatic ignition. Enertech/CTC has a desire to create an accessory with Automatic ignition to a modern wood burning boiler. Today there is no boiler on the market that can ignite firewood Automatically without the introduction of paper and sticks.

Swedish sawmills of today suffer from unsatisfying economy with high costs and low benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of Automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner. Iggesund Timber AB has the possibility to grade logs Automatically with TINA, a two way gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are mainly manual but can in some rare cases be Automatic.

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.

The purpose with the study was to find a pattern in the behaviour of dairy cows which could be related to their social rank. A behavioural study was conducted at the University Cattle Research Centre (Kungsängen) in Uppsala, Sweden. The study included 12 lactating dairy cows, 6 high ranked and 6 low ranked. The cows were housed in a loose housing barn with an Automatic milking system (AMS) to which they had access 24 hours a day. During the experiment the total number of cows in the barn was 46.

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.
