Attityder till implementering av precisionsodlingsteknik :

Different techniques for Precision agriculture have been available during the last decade. Some of them are more widely used than others. The main purpose of this thesis was to investigate the different attitudes to Precision agriculture that exists among farmers and advisors in Sweden. Eight advisors and sixteen farmers were asked for their opinion of a number of specific techniques for Precision agriculture, such as yield-mapping, precision liming, the Yara Nitrogen Sensor and site-specific fertilization with phosphorous and potassium. They were also asked to describe the way in which the counselling in Swedish agriculture is used and also about it's importance for the adaptation of new techniques. The high costs are mentioned to be one of the most important reasons why precision agriculture hasn't been more widely spread. Several farmers refer to their farms as too small to bear the costs that come with the techniques. The individual interest for technique among the potential users plays an important role.

Är GPS-styrning lönsamt :

GPS is perhaps the future in agriculture. The next years will show it but the precision becomes only better and better and the number of users becomes only more and more. This work shows experiences from today's users and how the profitability can be improved on a farm with normal plant cultivation. The aim is to show how big the actual advantage can be to have a GPS and how good precision there is with the equipment. John Deere and Trimble are the big producers of GPS equipment to the agriculture.

Snabbhet och precision hos det visuella korttidsminnet för randmönster och ovaler

Den här uppsatsen handlar om korttidsminnet (arbetsminnet) och dess kapacitet att lagra och processa information. Ett perceptionsexperiment som utfördes ger en inblick i hur korttidsminnet fungerar i praktiken och innefattar randmönster och ovaler som stimuli. Responstid och precision mäts och jämförs med avseende på betingelser som position och orientering. Uppsatsens hypotes är att samma respektive olika position på stimuli har betydelse för både snabbhet och precision. Resultatet bekräftade denna hypotes.

Företagsrekonstruktionens misslyckanden : Har rekonstruktören en roll i det?

The majority of the Swedish population were self-provided within agriculture a hundred years ago. Times do change and today the situation is the other way around - most of us live within city boundaries and only few work with farming and related agricultural businesses. One thing that has not changed though, is the need of supplies from Swedish agriculture.What do we think of those products? Are we even aware of the connection between us and agriculture? The Federation of Swedish Farmers, LRF (Lantbrukarnas riksförbund), started their project to strengthen the link between consumers and producers in 2008.This paper is part of the project and its aim is to investigate consumers' views and values upon the effects and products from Swedish agriculture.Opinions and values have been studied through interviews influenced by phenomenology. The results show that the informants in general had a positive approach and thinking concerning the products and effects from Swedish agriculture.

A resource based view of productivity, firm growth and technical management tools : a case study of Swedish large-scale farms

The past and ongoing structural change in Swedish agriculture has led to an increasing number of large-scale farms. The biological factors associated with large-scale farming operations may cause increasing variability, risk and reduced yields due to sub-optimal timing and management of field operations. The theory of economies of scale suggests that largescale production may benefit from lower costs due to scale efficiencies. Thus, large-scale farms may face cost reductions in terms of long term inputs factors, e.g. agricultural machinery.

Ask.com, Web Wombat och Yahoo: En studie av två globala och en lokal sökmotor.

This thesis is focusing on how global and local search engines retrieve information from the local domain. The three search engines tested are the global search engines Yahoo, Ask.com and the local search engine Web Wombat. The questions we examined were: which search engine has the best retrieval effectiveness? Could there be other reasons than retrieval effectiveness, to choosing a local search engine?For our test we constructed 20 questions related to Australia.We chose to divide the questions into topics like nature, sports and culture. For all questions we evaluated the relevance of the first 20 hits.

Vad bidrar till valet av precision i produktkalkylen?: En fallstudie om diskrepansen mellan teori och praktik inom produktkalkylering

Studies show that activity based costing (ABC) is not widespread in practice even though it has been present in the academic world since the 80's. This thesis examines the reasons for the discrepancy between theory and practice through a case study of a Swedish manufacturing company. The intension is to answer the question of what contributes to the choice of precision in product costing.We found arguments for increasing precision in product costing but not to the extent of a full-scale ABC implementation. The company's estimation of the value of increased precision. In the study three company unique factors were isolated that affected the company's estimation of value; drifting purpose of product costing, historical use of product costing and knowledge about product costing..

RTLS - real time location systems : an inventory study for agriculture applications and requirements

The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture. In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.

Evaluering av återvinningseffektiviteten i Svensk Medicin och Google Scholar med medicinska frågor ur Fråga doktorn.

The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the measure used was precision.

Klimatanpassning och lantbruket i Värmland : Klimatförändringarnas upplevda effekter på lantbruket och olika aktörers åsikter om klimatanpassning

Climate change is a global and slow process that affects humans all over the world. Climate adaption within agriculture is important to reduce the risks that agricultures are exposed to because of climate change.  Through climate adaption you can improve the positive effects and take advantage of them optimally. How the climate change affects agricultures varies depending on regions and societies. The purposes of the study are to examine how different actors experience the impacts of climate change on the agriculture in Värmland.

Google, Yahoo! och Live Search: en evaluering av tre webbsöktjänster

The purpose of this Master?s thesis is to evaluate three general query-based web search engines. The search engines chosen are Google, Yahoo! and Live Search. The topics, which where transformed into twenty queries, are based on real users? information needs, taken from an ask-a-question service.

En precisionsstudie av förstärkt verklighet som positioneringsverktyg

This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

Jordbruket, en del av vår identitet En studie om Frankrikes stöd för EU:s gemensamma jordbrukspolitik

AbstractThe European union experience sometimes difficulties in advancing its work due to the member states? different ambitions and interests. The budget is one common tool that the member states can use in order to implement different policies according to their preferences. A large share of the budget is presently tied up in the CAP, the common agricultural policy. This share could be spent in another area and by doing so the EU could take a slightly different direction.

Förbättrad precision vid ankomstkontroll

Examensarbetet utfördes på Balco AB i Växjö, som tillverkar och erbjuder balkongsystem påtotalentreprenad. Eftersom Balcos ökade omsättning har lett till att ankomstrollen inte längre kan utföras medtillräckligt hög precision, så har produktionsplaneringen blivit lidande. Syftet med projektet var därför att Balcoska kunna ankomstrapportera inkomna aluminiumprofiler från underleverantörer på ett smidigt sätt, samt medhög precision.För att lösa Balcos problem vid ankomstkontrollen, så att de enkelt kan rapportera in och få en god översiktav ankommit gods, har projektgruppen kommit fram till tre olika alternativa lösningar. Dessa lösningar ärstreckkodssystem, RFID-system och manuell identifiering. För bästa resultat, och användning avidentifikationssystemen, är det troligtvis nödvändigt att ett MPS-system implementeras.Slutsatsen och rekommendationerna innefattas främst av en lösning med ett streckkodssystem, men där denprimära nyckeln till ökad precision och kontroll av ankommande gods ligger i att införa ett väl fungerandedatasystem..
