Konkurrensbegränsning genom selektiva distributionsavtal inom den schweiziska klockindustrin
Sammanfattning Selektiva distributionsavtal används inom många branscher som ett sätt att reglera handeln med produkter och som ett verktyg för att selektera återförsäljarna. Det senaste året har dessa avtal kommit att nyttjas även inom klockbranschen. Det är en speciell bransch där varumärkena får allt större betydelse och det bidrar till en starkare position för de företag som äger och levererar produkter av de specifika varumärkena. Syftet med detta arbete är att utreda huruvida de selektiva distributionsavtalen medför en begränsning av konkurrensen och om så sker, vilka faktorer det är som skapar begränsningarna. Vidare har en diskussion förts om de villkor som nyttjas verkligen är förenliga med lagstiftningen.
Ergonomiska förhållanden för mjölkare i olika mjölkstallar :
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.
Hållbar växtnäringshantering i Stockholms län : En aktörsanalys
Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.
När trädens rotsystem får bestämma : En intervjustudie med en grupp yrkesverksamma inom anläggning av hållbara gröna miljöer.
ABSTRACTThis pilot study examines the knowledge about tree root systems amongst five treeplanting professionals. The aim is to find out the professionals? collective knowledge ofthe nature of root systems of various trees used in green areas. Furthermore; to explorehow the professionals adapt landscaped green areas to the tree root properties in asustainable manner. Questions: Which tree species have special root properties toconsider and how do the professionals utilize this knowledge? And: How do theprofessionals in general adjust planting according to the root systems of trees in areas tocreate sustainable green environments?Interviews with the professionals were performed.
Förslag till ny multihall i Mölndal. Användning av BIM vid projektering i tidiga skeden
The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Radioräckviddsberäkningar för flygande plattformar
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.
Inte vet jag vad jag håller på med e. : En beskrivning av partikel-e i dellboskan i två delar. Distribution och funktion.
Denna uppsats syfte och mål har varit att undersöka distribution och funktion för den i dellboska partikeln e. Undersökningen utgår från material transkriberat dels från egna inspelningar, dels inspelningar från Swedia2000projektet. Analysen uppdelas sedan på två delar; en första grammatisk undersökning för att fastställa regler för distributionen, somgenomförs utifrån skribentens och informanters språkkänsla samt konkordansundersökningar. Dessa resultat ligger sedan till grund för undersökningen av partikelns funktion i diskursen utifrån definitioner av diskursmarkörer. Slutligen har undersökningen visat att partikelntroligtvis kan införas under begreppet final dubblering av negation, samt också kan definieras som en diskurspartkel med funktionen att signalera övertygelse om att det som sägs är riktigt, och något som inte bör ifrågasättas..
Erfarenheter av några utfodringssystem till får :
The evaluation of the function of the feeding of sheep herds is suggested to involve the work
effort, the fulfilment of the nutrient needs of the sheep and the feed waste. Mechanisation of
the feeding can be very simple or include high degrees of mechanisation.
Three different farms, representing different levels of mechanisation are presented.
Descriptions and analysis of the feeding systems including mechanisation, work effort and
estimations of the feed waste are made on each farm. The herd with the most advanced feed
mechanisation included a rolling feed band and mix wagon. The other farms were partly or
little mechanised including ad lib feeding from big bales and manual distribution of hay and
concentrates.
The most mechanised farm was able to feed a large herd of sheep at a low work effort and
little feed waste. However, the investment in machinery has to be weighed against the
improved efficiency.
Usability för svenska folkbibliotek : En undersökning av svenska folkbiblioteks datorsystem med hänsyn till användarvänlighet.
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.
Analysis of Intent Specification and SystemUpgrade Traceability
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.
Standardiserande CAN drivrutiner
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.
