In this thesis a first order differential supply response model, the Linear Approximate Acreage Allocation Model (Holt, 1999), is used to analyze the competition between ethanol (sugarcane) and food crops (soy, corn, cotton, rice and orange) in Brazil. In this linear multi-crop supply response model total land is assumed to exogenous, leaving the shares to be estimated along with elasticities betw
The ECB has the ultimate responsibility for the single monetary policy. The ECB’s goal is maintaining price stability over the medium term; this means ensuring inflation stays in the region of 2 percent. If some EMU members are more favoured by the ECB’s interest rate decisions then this would cause implicit problems and overall, the monetary union would face problems regarding structural divergen
Den här uppsatsen undersöker de positiva och negativa effekter en subventionering av utbildning framkallar i en ekonomi. En investering i humankapitalet är en viktig del av produktionen och påverkar därmed inkomstnivåerna i positiv riktning. Samtidigt ger subventioneringen upphov till kostnader som kan påverka produktionen negativt och förorsaka låga initiala inkomster, lägre konsumtion och lägre
During the last ten years several international studies and reports have paid attention to the sexual life of HIV-positive homosexual men, while in Sweden this area is unexplored and has to be investigated in the future. The lack of knowledge of the sexual life of HIV-positive homosexual men risks to stigmatize still more this group of people who are already exposed in society. The aim of the repo
It has been argued that the choice blindness effect is only present in quick and intuitive tasks such as preference decisions for faces or shapes, and not when it comes to more important and deliberative decisions involving issues like moral, political or religious beliefs. To answers this criticism, using a method inspired by close up magic, we investigated whether participants would notice chang
Problem: To develop high performance washing concept, while being simple and environmentally friendly. The concept is to be used as a base for more detailed design of a mobile waste bin washing machine where the driving force is the demand for cleaner working environment. Method: The market is researched in order to evaluate the competition as well as to get a deeper knowledge of the problem at ha
Objective: The objectives set out for this Master Thesis were: · How should a coffee machine for home use be designed and which features should the machine provide? · How should an experimental prototype be manufactured? · How should an experimental prototype be tested? Method: The thesis is written as a product development report and essentially follows the methods described by Ulrich and Eppinge
The objective of this thesis is the integration of the TRIZ-method (Altshuller) and the AAK-method (Roth)into the industrial design engineering process model and the validation of the integration by the industril design engineering project "Conceptual design of an armchair for elderly people".
To allow the user interface in a mobile phone more space, slide modules are implemented. The usage of slide modules introduces many new challenges when designing a mobile phone. New solutions to these challenges is the main scope for this thesis. Nokia currently has several different slide phones out on the market implementing some sort of slide module. The slide module provides extra space for th
This Master Thesis project is performed at Tetra Pak in Modena, Italy. The overall objective of the overall Locking Pin project as this thesis project is a part of, is to understand the root cause of a failing locking pin. The locking pin is located in a filling machine and failures due to fatigue. The function of the locking pin is to bind up the filling pipe to a pressure flange. The locking pin
Problem descrip-tion: Design codes today are generally based on simplified hand-book calculations, which cause problems with the application of FEM. There are no recommendations in the design codes on how FEM shall be applied when performing fatigue life analysis of welded joints. The difficulty lies in how the results shall be interpreted. Objective: The objective with this project is to establis
Sealings are an important part in the industrial robot. One important property of the seal is to keep all particles and fluids from the outside, away from the important components inside the robot. Another important property is to keep the oil and grease inside the robot, and prevent leakage. The seal also prevent leakage inside the industrial robot and reduces the risks of sensitive components to
Texo AB is a private company which is specialized on development of looms for production of paper machine clothing. The company is located to Älmhult in southern Sweden and today employs about 90 persons. The calculation job treats 4 independent tasks, of which 3 is dealing with the same type of machine which is almost at the prototype state at the moment. The new machine TC 74 is a cam controlled
This Master Thesis has been completed at the research and development department of Sandvik Mining and Construction in Perth, Australia. The scope of it, specified by Sandvik, includes two main task, both part of greater product development processes at Sandvik Mining and Construction. The first task is an incremental improvement of an existing product. Sandvik believes their patented Dual Propert
The production of core material/blocks is divided in multiple steps. Before the hardening process the blocks are placed horizontally in stacks of 10 on a pallet. Between each block plastic spacers are placed to insure a spacing of 5 – 8 mm in between the blocks. This is done to achieve a better water flow and cooling efficiency in the hardening chamber. The use of plastic spacers complicates work
This master thesis explores the usage of stainless steel in mobile phones. The first part is an introduction to stainless steel which explains the properties of the different stainless steels, and also the most common methods used for sheet metal production. It is concluded with a selection process to determine which stainless steels are best suited to be used at Sony Ericsson Mobile Communication
Discussion The trend on the mobile phone market indicates that mobiles with advanced texture will be in demand. Sony Ericsson Mobile Communications AB would like to examine what possibilities there are in the field for texturing. In 2006 they introduced the mobile phone W850i with advanced texture on the market and now they want to know more about different techniques for texturing in the future.
NIMCO Controls AB is a company located in Malmö, Sweden, that manufactures hydraulic valves mainly for the farming industry. They proposed me to work on three independent design projects to renew their product range. The first topic was a platform research for handgrips. As the company uses lots of different lever systems that need a handle, the main objective was to design a platform which deriva
The removal of snow and ice from aircraft prior to take-off is a major task at all airports located in cold climates. Currently the removal of ice and snow is carried out using large amounts of costly and environmentally harmful glycol that is sprayed onto the outer surface of the aircraft. Tougher environmental regulations and a cost conscious market have created a growing need for alternative me
Background The telecommunication market is characterized by short product life cycles why the time of the development process has to be minimized. This means lack of time in the development process why known and tried design solutions are being used to a great extent instead of trying new and less conventional solutions. The market is also striving to minimize the size of the mobile phone while in
