Effect of cow traffic system on cow performance and AMS capacity

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

Free cow traffic in automatic milking systems (AMS) : a case study on nine commercial dairy farms in Sweden

In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.

Identitetens gränser- en uppsats om invandrares identitetsskapande i en svensk mångkulturalistisk kontext

This essay discusses immigrants? prospects of constructing an identity in a multicultural society like Sweden. The discussion is primarily theoretical but offers a few empirical examples to demonstrate its relevance. Furthermore, the ontological standpoint of this essay draws on an understanding of the world and our knowledge as constructed which implies that identities are also constructed. The process of identity making is further understood as a relational process in which others recognition is central to the individuals own understanding of his or hers identity.

Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

GALS,Design och simulering för FPGA med VHDL

Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be reduced. GALS (Global Asynchronous Local Synchronous) is a wrapper that wraps a synchronous block and provides it with a clock. Multiple GALS-elements will make the whole system. The clockfrequency may be independently adjusted between each block.

Modellering av indunstning på Södra Cell Mönsterås

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :

Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.

Professionella ex inom missbruksvården : En kvalitativ studie om vägen från drogmissbruk och kriminalitet till en karriär inom behandling

The aim of this study was to examine how "Professional Exes", individuals that have exited a drug abuse and a criminal career and further are educated to work in the addiction field, transformed their identity and which factors that were significant in the process. The result of this study are based on semi-structured interviews with five Professional Exes and shows which specific factors in the process that contributed to the transformation and what kind of difficulties and barriers that existed during the process. The study suggests that, among other things, identification with others exes and the 12 Step Program are significant factors in the process. Furthermore, the study suggests that a difficulty in the transformation is that residues from the previous identity such as a poor self-esteem occurred in some situations..

Politecast : ett nytt kommunikationsprimitiv för trådlösa sensornätverk

Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.

FMCW-radar för mätning och beräkning av målbana

I detta arbete studeras möjligheterna att använda s.k. "Frequency-Modulated Continuous Wave radar" (FMCW-radar) för att mäta avstånd och radiell hastighet till ett mål. Vidare undersöks möjligheten att använda en följd av sådana mätdata för att skatta banparametrar för ett mål. Vi utför en två-dimensionell Fouriertransform på radardata. Genom att söka upp maximala värdet av transformerade datas absolutvärden erhåller vi en grov skattning av avstånd och radiell hastighet.

Utveckling av generell testklient för Nordic Growth Market

Development and accuracy tests of advanced exchange trading systems require well adjusted tools for testing. Aptness of these tools are probable to have a major impact on identification of bugs and verification of new functionality. Identifying erroneous parts and bottlenecks of the trading system is of outmost importance for the exchange as a whole since stability and correctness are two of the determinant factors its viability is measured by. This paper covers how this test-tool was created and the motivation behind the design choices made. The tool was created with the goal to be broad enough to cover the majority of cases that could arise, fast enough to be able to test the trading systems speed limitations (i.e.

Mat, måltider och maskuliniteter

To complete an overweight treatment program is associated with better weight loss. Previous studies have in principle focused on drop-out from the entire program, not individual parts of a program. Factors previously shown to influence the patients´ weight loss results are: frequency of individual meetings with a professional, the lack of social support from family or friends, the lack of motivation and in a few studies vacations. In several studies the drop-out patients have stated that their reasons for drop-out were dissatisfaction with the staff and the program design. Drop-out has also been shown to be connected with difficulties in adherence to the diet.

Fiktion och Icke-fiktion i Göteborgshändelserna är en roman som är skriven av Jörgen Gassilewski och utgiven av Albert Bonniers Förlag

This essay concerns the fantastic and its position in narration. The fantastic's defintion is based on Martin Horstkotte's defintion in The Postmodern Fantastic and the essay focuses on the noncontextual aspects such as the clash between two incompatible fictional worlds and the absence created. Instead of the ordinary identification of the established fictional world with realism and our reality it is suggested that both of the colliding fictional worlds are fictive and that the established one not necessarily need to be realistic. Exampels on how the fantastic takes place on the syntagmatic level in a narration is drawn from the short story ?Samvetets fantasi? by Clas Livijn when analysed with Peter Brooks' closurebased narratology theory in Reading for the Plot.

Biblioteks- och informationsvetenskap som kunskapsområde En bibliometrisk studie.

The objective of the study is to map the cognitive structure of Library and Information Science, using a quantitative, bibliometric method. This empirical study shows how co-citation analysis combined with word-frequency analysis can be used to describe the subject content of the field. The research questions to be answered are: -Which clusters of authors can be identified? -How can these clusters be described in respect of their subject content, if the descriptors associated with the authors in the clusters are counted? The results show that the cognitive structure of Library and Information Science can be described by 13 clusters of authors, where each cluster is representing a specific aspect of the subject- domain. For the description of the subject content of the clusters, descriptors DE of the LISA database have been used..
