Tetra Pak is developing a new flexible packaging machine called Tetra Pak C3/FLEX. With this machine it will be possible to manufacture packages of different volumes with the same cross sections. A volume change denotes that the repeating length of the packages changes. This results in a variation of the web velocity through the machine. When the web velocity changes, the emitted amount of heat to
An EU strategy to reduce carbon emissions and become more energy independent was the introduction of Directive 2002/91/EC. The EU member states were required to transpose a directive into national legislations. This resulted in that Sweden admits the law on energy certification of buildings. Certified energy expert who declares the buildings must be certified energy expert and independent of his p
This thesis is to research the relationship between inflation and economic growth of China from 1978 to 2007. No unambiguous conclusions on this problems have been obtained from previous literatures. This thesis will employ co-integration and error correction models accompanying with correlation matrix and the Granger Causality Test to examine the inflation-economic growth relationship. The data i
Previous research has found clear spatial patterns of agricultural supply, both in pre-industrial Europe (Grantham 1978; Grantham 1989; Kopsidis 2009) and in the less developed countries of today (Benziger 1996; Stifel & Minten 2008). The spatial structure of farming intensity is mainly attributed to the declining net-returns with the distance from the market. This paper examines the impact of
En jämförelse mellan Stendhals roman "Rött och svart" och filmen med samma namn av Jean-Daniel Verhaeghe.
Problem discussion: BCC:s product portfolio includes a transplanting machine that plants seedlings from trays to the field. The machine is more than 10 years old and need improvements to meet future demands from customers around the world. The main issues are that the machine does not have the capacity to detect missing plants from trays, the planting speed needs to be higher and the row distance
This thesis is a concept study performed at Caran AB by order of Volvo Car Corporation, VCC. The background is a market research performed by VCC. From the research, a need for a product that facilitates reaching the trunk level in Volvo’s SUV, XC90, was recognized. It was also found, that dogs seem to find it difficult to get up in the trunk, why dogs have been accounted for during the developmen
Before a processing unit is taken into production it is prepared with water instead of product, among other things it is sterilized this way. When this preparation phase is done, the water is pushed out with the product that is about to be processed. During this phase a mixed zone of water and product occurs. This mixed zone of water and product results in a cost for the producing company due to l
FAS Converting Machinery AB makes machines for plastic-bag manufacturing. The company is located in Ystad in the very south of Sweden. They want a new method for detecting the perforated joints between the plastic-bags, to make the machine able to count the number of bags rolled up. The current method uses a spark that goes through the small holes in the perforation. That method does not work at h
This master thesis has been made on behalf of Sony Ericsson in co-operation with Machine Design at Lund Institute of Technology. The background is a need within Sony Ericsson to test moulded plastic parts before they are assembled together to a phone. There are today various specified tests that are made on every single phone before it is launched, but they are all made on complete assembled phone
This resport is the result of a Master Thesis project between Winfoor AB and the Division of Machine Design, Faculty of Engineering, LTH, at Lund university. Winfoor AB has developed a new technology for producing wind energy. This technology utilizes the motion of a wind subjected sail cloth (wind element).The wind generates an ascillating movement of the wind element, from which energy can be p
Westinghouse Electric Sweden AB has for the production of Optima 3, decided to replace the existing welding equipment with a new laser-welding process, to weld the spacer that keeps the fuel rods in place at the fuel box. The author wrote this master thesis for the department of Mechanical construction, MKON within the Faculty of Engineering of Lunds University. The goal was to examine Westinghous
Our master thesis is performed for Faiveley Transport AB, Landskrona. The company’s main business area is development and assembly of complete brake systems, wheels and couplings for railway vehicles. The company is currently working on a project, V-Brake, to develop a new competitive brake. Earlier two students, T. Persson and J. Mårtensson, have been working with the development of the brake, bu
A built rivet machine is experiencing a bending moment that makes it "yawn" when it rivets, which causes a bad rivet operation. The purpose is to analyze and find the reaseon for the caused problem. Method: A computer based machine design analysis will be performed and the achieved results will be compared with actual measured ones. When a satisfied result i achieved redesign will be per
This thesis project was to develop a module for a forest precision seeder. The project is made at BCC AB. BCC is a worldwide supplier of forest seed centre and containerized nursery equipment. BCC develops, designs, produces and sales machines for forest seed handling. BCC s existing precision seeder can not handle seed that are tinier than 1 mm in diameter. With a growing market in countries with
