A quantitative analysis of global kiwifruit trade
New Zealand is currently the third largest global producer of kiwifruit and thus plays an important role in the international market. Exports of kiwifruit are also of significant horticultural value for New Zealand and in 2007 the kiwifruit industry accounted for export values of NZ$790 million.
The global kiwifruit market has experienced substantial changes in recent years and is likely to change significantly in the near future due to developments in production sources, adjustments to trade policy settings and shifts in consumer preferences. The New Zealand kiwifruit industry needs to consider what the impacts of these changes might be so that future strategies can be constructed effectively.
Little quantitative modelling has been done in New Zealand to consider the impacts of changes to the global kiwifruit industry. The major contribution of this research was the development and calibration of a kiwifruit industry-specific partial equilibrium trade model. The model was then used to examine the impacts on New Zealand producers of these trade-related changes in the global kiwifruit market.
Excess och kontroll : an Analysis of Annika Larsson?s Videos Pink Ball and Poliisi
The aim of the thesis is to identify and investigate central themes in two video artworks, Poliisi and Pink Ball, by Swedish artist Annika Larsson. Moreover it is an investigation of the configurations of violence, and an enquiring whether these works have a social-minded intention.Elements in scenery, framing and narration are analysed with the term ?crystalline regime? (régim cristallin), described by French philosopher Gilles Deleuze, which defines the artificial as opposed to the purely representational. Processes within the narrations of the two works are analysed as rituals, which leads to an investigation of an internal sign-system and to the question whether the rituals in these works have a function. Theory by French philosopher Georges Bataille is used to analyse the ritual with no external purpose, which aims at an intense experience of life.
Jämställdhet i förskolans verksamhet : En observationsstudie om hur pedagoger förhåller sig till flickor och pojkar ur ett könsperspektiv
The purpose of this study is to look into if the pedagogues who participate in this study treat children differently depending on their sex. The purpose was then divided in three research questions which were: Attention: How much verbal attention and eye contact with the pedagogue are girls/boys getting? Choice of words: Are there any differences in the choice of words the pedagogues are using against girls/boys? Address: How does the pedagogue address girls/boys, are there any differences? The tone of the voice and how the pedagogue address girls/boys belongs in this category. The study was observed with video camera in four different circle time situations, two circle times for each preschool. Data were then analyzed with an observation schedule based on the three research questions.

Realistisk integrering av 3D i en verklig miljö
Det kommande innehållet i detta examensarbete kommer att handla om min frågeställning som berör integrering av 3D objekt i en verklig miljö: ?Vad finns det för metoder att integrera 3D objekt med en verklig miljö och hur gör man??.Arbetet och efterforskningen har utförts i Söderhamn, där jag har arbetet hos 3D animationsföretaget Magoo 3D Studios. Med hjälp av anställda på Magoo har jag genomfört experiment för att själv prova på de olika metoder som ska kunna besvara min frågeställning.Som resultat så har jag kommit fram till att alla divisioner inom 3D, som modellering, texturering, ljussättning och compositing kan bidra till realistisk integrering på sitt eget vis, dock i olika utsträckningar. Mina experiment har alla varit lyckade och jag känner att de är på rätt väg mot fotorealistiska resultat.I slutändan så upplever jag att de metoder som bidrar mest till en realistisk integrering är en bra ljussättning med en Image Based Lighting metod, samt att ha bra vetskap om hur en kamera fungerar för att sedan kunna efterlikna dess typiska drag samt artefakter så bra som möjligt.Kombinerar man dessa metoder så är man en bra bit in på vägen till fotorealism där man inte längre är säker på om datorgenererade bilder är riktiga eller inte..
Utredning av laserskärningens materialpåverkan inför drag- och slagprovning : Teknisk Fysik med Materialvetenskap
An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.
Effekter av "Billigaste väg" för Stora Enso Skogs transportverksamhet :
Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.
Att mötas under en övervakningskamera - En studie av Malmö stads trygghetsarbete
This essay is about security and safety in the city. More precisely it is concerned about the role of the institutions that aims to raise the perceived security and safety and their understanding of these concepts. I study two of the municipality's project in this field in the city of Malmö. Documents concerning these projects are analysed with a discourse analysis inspired by Chantal Mouffe and Ernesto Laclau as well as Michel Foucault. The two projects consist of one discourse each; the surveillance discourse and the discourse about meetings.

This report is about how HDR (HighDynamicRange) can be created and used in combination with Tone mapping. This work has been carried out together with Kapsch TrafficCom AB in Jönköping.The objective of this project is to:Evaluate and investigate the effects given to pictures by HDR and tone mapping.Evaluate if the technology may lead to improvements in Kapsch?s systems.To construct a program which is able to handle some form of tone mapping or HDR-algorithm.These questions will be answered in this report:What kind of effects has HDR and tone mapping-algorithms on pictures?Can the HDR-technology give better data in Kapsch?s systems?The research method used in this report is called action research. This means the authors has investigated the technology by reading different documentations and by testing different algorithms to see what kind of result they give. The report describes some of the tests made to see if the technology is appropriate in Kapsch?s system.There is two smaller reports made by the authors which documenting some of the work.The first report describes the work with different settings for a camera to create pictures with HDR-quality.
Att undervisa förskolebarn - förskollärares strategier
This study gives voice to which strategies preschool teacher?s use they teach preschool children in different performance tasks. The overreaching aim of this study was to find out what teacher give expressions to, verbally and in action, and what educating strategy they use when the purpose is that the children are to learn something specific. The theoretical starting-point of the study is a phenomenography research which aims in finding and systematizing of forms of thought in terms of which people interpret significant aspects of reality. The study has a Sociocultural perspective which means that the structuring occurs through choice of which activities children have access to observe and engage in, as well as through in-person shared endeavours, including conversations, recounting of narratives, and engagement in routines and play.
Gud i fängelse : Religion som copingstrategi i anstalt
Denna uppsats undersöker remediering och minne i Henry Parlands roman Sönder (om framkallning av Veloxpapper). Vad gäller remedieringen är det romanens efterhärmande av bildmediet och filmmediet som analyseras. Undersökningen av minne i Sönder gäller hur minnet är kopplat till ett fotografiskt seende, som i sin tur är förbundet med romanens remediering av bild- och filmmedierna ? som möjliggör samt förutsätter detta seende. Analysen bygger på en motivstudie av det fotografiska seendets inslag i romanen, och dess betydelse för levandegörande av minnen. Det går att tala om en strukturalistisk teoritillämpning, där detaljerna får belysa helheten och helheten får belysa detaljerna.
Lönsamhetsbedömning av utökad MR-kapacitet på Karolinska Universitetssjukhuset
This thesis analyses how a radiology department at the largest hospital in Sweden, Karolinska University Hospital, most profitably could expand its capacity for investigating cancer patients using magnetic resonance imaging (MRI). The queues today for patients waiting to be scanned are long, which delays the start of cancer treatments. Meanwhile the hospital has a budget deficit of half a billion SEK, which make any expansion hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these.
Fallstudie av produktionschefers ledarskap
The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.
Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala
There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..
