Flerpartslogistik med fokus på rutter, fyllnadsgrad och miljö
The globalization has increased the trade between different places and countries. Products are now available from all over the world, but this requires transports that have consequences in the environment as well as the economy. New professions are creates that do formality, organize, administrate and implement other businesses transports. Their operations are between the business and customer and they are called logistics companies. The purpose of this report was to study third-party logistics and why more and more companies use this logistics services.
Injektion till katt ? injektionsassocierad smärta samt injektioner i praktiken
Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain.
When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced.
Facts about the causes of injection-associated pain have been studied in a literature review.
PARAMETRISERAD DESIGN APPLICERAD PÅ EN MOTORSÅGSKEDJA
The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.
Förstudie för en vindkraftpark på Malmölandet i Norrköping : En undersökning av förutsättningarna för en vindkraftpark på ett sen tidigare planerat område
This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.
Att tala är silver, att tiga är guld? : - En kvalitativ studie om interaktion i samband med talad engelska under engelsklektionerna
Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).
Kommunfullmäktigeledamöters sociala representation -en fallstudie i tre svenska kommuner av kön, ålder och etnicitet
The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.
Prövning av liggtidssensorer som indikator på förestående kalvning hos dikor
The aim of the study was to find repetitive behavioral patterns pre calving that could be used as indications of calving in beef cattle. In the study sixteen Standing- and lying down sensors were attached to the leg of sixteen beef cows. Ten of the sixteen beef cows gave birth to calves during the trial period. From these ten cows, data from six cows were used to assess the sensors fitness for use as calving indicators. The analytical part of the experiment was divided into two parts, calculation of divergence of mean lying time within different time intervals, and the number of lying bouts.The first part consisted of optimization of an equation used to highlight divergence in mean lying time within eight different time intervals (3, 6, 9, 12, 15, 18, 21 and 24 hours).
Utfodring av rapsfoderråvara i fodersystem till mjölkkor
The feed is a major cost in the dairy production and there is a constant interest in findingalternative cost-effective feedstuffs. Competitive dairy producers have to seek ways todecrease their production costs and the pursuit of cost-effective feed rations contributesto lower costs of production. An interesting group of protein concentrates are rapeseedproducts like ExPro (heat treated rapeseed) which have during the autumn 2008 andspring 2009 been very favourable compared to other protein feeds.This study focuses on the feedstuff products ExPro and Raps-Drank 60/40 (rapeseeddistillersgrain). The potential use of ExPro in dairy cow feed rations are also explored.ExPro is a well known feedstuff but Raps-Drank 60/40 is a relatively new product andnot known for many farmers.A field study on the use of rapeseed products was made on a limited number of dairyfarms. The main purpose was to study the management of the feedstuffs on the farms.The Farms were selected in cooperation with two local extension services.
Konstruktionstudie av en ångexpander
This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.
Utveckling av beslutsstöd för kreditvärdighet
The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.
GMO Food Products - The issue of marketing and selling them in Europe.
Title: GMO Food ProductsThe issue of marketing and selling them in Europe - A Business and Legal Perspective.Author: Shane KingSupervisors: Anneli Carlsson and Ewa RabinowiczProblemThe European Unions regulations in regard to GMO?s and the approval process for both release into the environment, and onto the market, has been under fire by the USA along with Canada and Argentina. The WTO has ruled on this issue in favour of USA et al.The problem that was identified was in regard to consumer opinion in the EU. How could the EU meet its numerous international trade obligations while at the same time meetingthe needs of the citizens of the Union? Added to that was the issue of whether or not the?EU? perspective was indeed an EU perspective or rather the perspective of a fewMember States.
When I die, I want to be recycled - a study of the view of the funeral industry on the handling of metals in cremation
Kremering är idag det vanligaste jordfästningssättet i Sverige, de allra flesta som avlider kremeras och gravsätts i urna. Frågan om hur de metaller som finns i kroppen men inte får plats i urnan hanteras har hittills inte väckt så stor uppmärksamhet, speciellt inte ur miljösynpunkt. Dock handlar det om åtskilliga ton metall som varje år grävs ner på kyrkogårdar runt om i landet. Denna metall påverkar dels miljön negativt, dels kommer det att ta upp mer och mer plats på kyrkogårdarna i framtiden, och att gräva ner metaller imarken är inte ett miljöoptimerat sätt att hantera dessa. Det finns dock andra saker än bara miljön att ta hänsyn till i denna fråga.
Simulering av simulinkmodeller med Extended Kalman Filter
Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.
Om behovet av ett avrinningsområdesanpassat skogsbruk
The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015.
The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.
