Optimering av antenndesign utifrån experimentella data
During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.
Utvecklingen hos nattskatta (Solanum nigrum L.) och dess bekämpningsbehov i konservärtsodling :
Black nightshade (Solanum nigrum L.) is a major problem in gardenpea cultivations
contracted by Findus AB, a Swedish food processing company. The main problem is that the
nightshade berries contain solanin and, thus, are not tolerated in the marketed product, which
is fresh frozen peas. In addition, berries have the same size and color as the peas and cannot
be separated at the factory. Black nightshades have the last ten years become a more common
weed in field grown vegetables in the southern parts of Sweden. This MSc thesis presents an
experiment conducted in 2005, aiming at developing a tool for predicting the need for control
of black nightshade in peas.
EKONOMISTYRNING AV BUTIKSVERKSAMHET: ? en fallstudie av modeföretaget ?Alfa?
The aim of this thesis is to examine how salesperson control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the control system. The main finding is that the company?s management control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..
Gottsunda torg : program och gestaltningsförslag för Gottsunda centrum
Det är mycket viktigt att förhindra att bekämpningsmedelsubstanser läcker ut i miljön
och orsakar skada. Lagstiftningen kräver därför att läckaget av bekämpningsmedel från odlad mark minskas. Olika myndigheter och organisationer har olika ansvarsområden
beträffande bekämpningsmedel. Bekämpningsmedelssubstanser kan, om de inte hanteras rätt, vara skadliga och därför finns det tydliga bestämmelser om hur dessa substanser ska
hanteras.
Många oberoende undersökningar visar tydligt på att det förekommer läckage av bekämpningsmedel i samband med att de används i behandlingar av odlad mark. Undersökningar har pågått under lång tid både i Sverige och i andra länder.
Ett flertal åtgärder och metoder mot läckage av bekämpningsmedel från odlad mark har framtagits och utvecklats som radikalt kan minska läckaget av bekämpningsmedel.
Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar
The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.
The Emerging Pricing Capability
The purpose of this thesis is to try to understand, with the help of existing theories and empirical findings, the parameters which are of importance in the development of the pricing capability. We have used a qualitative and abductive methodology approach. The empirical findings have been collected via semi-structured interviews which we have conducted via personal and telephone interviews. Seeing pricing as a capability within the company our theoretical framework mainly consists of the resource-based view and an article explaining and given proof how pricing can be seen as a capability. We also describe the most used pricing strategy today within business-to-business companies, the cost plus strategy.
Den uppklädda människan : en diskussion kring den gropkeramiska klädesstilen
This thesis discusses the dress code during the Pitted Ware culture on the Swedish island of Gotland. Eight Pitted Ware grave-fields have been analyzed; only 74 skeletons have been identified with some sort of ornament that could have been attached to clothes. The grave-fields are rich in finds and in people nearly every age group is present. The analysis has shown that there are clear differences between the genders. The female always has some sort of seal tooth ornament around her waist and thighs.
Mätning av Mikroläckage i Dentala Implantat
Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss.
The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.
Framtagning av ny lager layout hos Allied Motion Stockholm AB - En studie om effektivisering av lager och intern materialflöde
This report is about the shear force design of reinforced concrete according to Europe?s common dimension rules, Eurocode. The purpose is to describe the calculation procedure and the background to the formulas and expressions that occurs. Furthermore results from different calculation methods (hand calculations and computer calculations) will be compared to see how they differ.The goal with this is to go through the parts of Eurocode dealing with shear force and that this will lead to a clear review of these. You should also be able to see how results and the calculation procedure differ between different calculation methods.
Implementering av Virtual Design and Construction: en
fallstudie av Veidekke Entreprenad AB
Den svenska byggbranschen står i nuläget inför en stor teknisk förändring, införandet av Bygg-informationsmodeller(BIM)/Virtual Design and Construction (VDC) i stor skala. Branschens olika aktörer ser olika vinster med implementeringen som kommer påverka hela byggprocessen, från projektering till förvaltning. Denna studie fokuserar på organisation och process i projekteringsskedet och grundar sig på en fallstudie av Veidekke Entreprenad AB. Företaget har implementerat VDC i delar av organisationen och i nuläget, efter lyckade pilotprojekt, utvidgas satsningen och implementering görs i större skala. Studiens syfte är att kartlägga Veidekkes VDC-mål och strategier, för att därefter studera process och organisation i projekteringsfasen och hur de bör utvecklas för att skapa goda förutsättningar för att VDC-målen ska kunna uppfyllas.

Kålgallmygga, Contarinia nasturtii Kieffer : en växtskadegörare på kål
The purpose of this paper is to examine what problems cabbage growers have with the
Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become
a larger problem for cabbage growers in several countries in Europe as well as in
Sweden. In Canada the problems are so severe that the midge is classified as a
quarantine pest and therefore certain rules have to be followed. I have collected facts
of the biology, host plants and reproduction of the Swede Midge, as well as the
growers experiences and the occurrence of the midge in Canada, Europe and Sweden.
The Swede Midge is hard to control because of its short life cycle and the larvae are
protected between the heartleaves of the plant. When the larva feeds on the growth
point the plant becomes distorted, in some cases several heads develop or none at all.
When the midge infests spring rape its flower buds become undeveloped and rosette
like.
Vilken effekt har lärkrutor på ogräsfloran vid ekologisk höstveteodling? :
This study forms part of the R&D project "Improved survival of bird chicks in organic fields" managed by the Rural Economy & Agricultural society in Uppsala. The skylark (Alauda arvensis) is a species that has decreased drastically in Sweden as a consequence of more intensive cropping.
Studies in England have shown that skylark reproduction can be greatly improved within
conventional fields, at a low cost, by establishing patches of bare ground (skylark plots).
Within conventional farming, herbicides can be used in case a weed problem arises due to
implementation of these skylark plots, whereas this is not allowed in organic farming. This study examined the effects of skylark plots on the weed culture in organic autumn-sown (winter) cereals and whether weeds might cause long-term problems to farmers.
The study was conducted in two parts; a field study and a review of the literature regarding the weeds observed. The field study was carried out in 2007 during three weeks in June and three weeks in July, on eleven organic fields with winter cereal in the vicinity of Uppsala.
