The project task is to install an industrial robot and to construct peripheral parts to an automation cell for a masspectrometer (MS) on Protein Technology. The MS is used to determine the concentration of different masses in a sample. The mass spectrum can be used for disease detection by determine which proteins that healthy people got and compare it to diseased people. The finished MS cell cons
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
We have conducted this master thesis for Heatex AB, located in Trelleborg. The company is the market leading OEM supplier of air-to-air heat exchangers. In a more and more competitive market, the demands on the design and the preparation for manufacturing are increasing making integration an important factor. Our work comprises the company’s design and preparation for manufacturing of cooling unit
Problem statement This thesis work was initiated since there are problems with the navigation devices currently used by SEMC, Sony Ericsson Mobile Communications AB. The problems with the currently used navigation devices are lack of ability to keep dust out and they don’t meet the demands from future applications like scrolling through large amounts of data, image editing and advanced web browsin
The purpose of this project was to reduce the production cost of the drive unit from AB Ph. Nederman & Co product Flowline with 50 % to make it more competitive, and the result is this report as well as a fully operational prototype. During the process I have looked into all of the functions of the existing product and have tried to improve them. The function which I have put most time and eff
For many years the benefits of using stockings that exert a pressure on the legs, to prevent and treat a number of health conditions, have been well known. For just as many years carers and caretakers have been struggling to put on these stockings onto the legs. The high compression strength of the stockings makes it very difficult to put them on the way one does with ordinary stockings. Today, me
The costs for producing machines have increased a lot in the latest years. For Presona this has meant that production costs for their main waste compactor needed to be cut in order to keep the compactor in their production line. The waste compactor was initially developed sometime in the 1960s when the price for construction materials and assembly allowed Presona to develop the compactor using a t
Interference fit assembly is a state-of-the-art technology for mounting cylindrical shafts into bores. Due to its extreme cost-efficiency it is used even in high-tech applications such as one of Bosch’s gasoline flow controllers. The picture below shows the anchor-needle connection. Due to electromagnetic incitation the assembly oscillates over 55 times per second. In order for the assembly to wit
Detta examensarbete har gått ut på att utveckla ett nytt avlänkningssystem till en myntsorteringsmaskin. Det utfördes på uppdrag av SCAN COIN AB som tillverkar bl.a. myntsorteringsmaskiner. För att kunna öka prestandan i deras modernaste myntsorterare SC Active 2200 var de intresserade av att undersöka möjligheten att använda en ny teknik för avlänkning av mynt. Det befintliga avlänkningssystemet
Realization of a Master Thesis is one of the mandatory parts of the Master of Science. The thesis was performed at the GUR/MBM mechanical development department at Sony Ericsson Mobile Communication in Lund, with supervision of the Division of Machine Design at the Department of Design Sciences, Lund University of Technology. The current consumption of mobile phones in standby mode has decreased a
This Master’s Thesis, under the Division of Machine Design at Lund Institute of Technology, was conducted at Presona AB located in Tomelilla, Sweden during the first half of 2006. Presona AB is a leading manufacturer of equipment for handling and compression of waste. The object of the thesis is to reduce the manufacturing cost of Presona’s heavy duty stationary compactor. This is acquired by rede
The issue of understanding how electrical and mechanical systems work and how the components interact is not a trivial issue for most people. To help students understand these systems and thereby increase the knowledge for the future engineers, educational computer games may act as an important learning platform. This project aims at aiding students in their effort to reach knowledge in the area o
The objective of this Master’s Thesis, entitled “How to increase tolerance regarding co-planarity when using larger shield cans”, is to find solutions for how to solder larger shield cans to the printed wired board (PWB) without losing shielding effectiveness. Advantages with larger shield cans, i.e. combining several smaller shield cans into one large with internal walls, are saved board space, e
Several hundred FDS simulations have been run using Monte Carlo analysis and probability distributions of input variables. The simulations have been run to investigate the propagation of uncertainty from model inputs to outputs in order to quantify uncertainties that could arise due to the choices of an FDS user. A method has also been presented for performing FDS Monte Carlo analyses. The results
E.ONs fjärrvärmeprodukt är eftertraktad av kunderna i de 40-tal nät som ägs av E.ON idag. E.ONs fjärrvärmekunder stannar länge och erbjuds en säker och prisvärd värmeleverans. E.ONs målsättning är dock inte bara ett stort antal kunder utan även en hög kundnöjdhet. Fjärrvärmens egenskap som bekymmerslös innebär ofta att kundkontakterna för privatkunder endast består av månadsfakturering samt ett år
In 2005 there were 18 500 accidents in the traffic in Sweden. 26 459 peoplegot injured and 440 people died due to the traffic accidents. When accidents in the traffic happens the one thing that makes the greatest difference in the outcome is the fast arrival of anyone from the Blue Light Organization (BLO) to the scene of accident (SoA). Minutes makes difference. Fire fighters, ambulance nurses a
De senaste åren har man sett en trend i att fler människor än tidigare äter mer nyttig mat. Till följden av denna konsumtionstrend har konsumtionen av produkter som innehåller mycket kalorier, fett, socker och salt minskat. Konsumenten idag ställer allt större krav på kvaliteten i den dagliga kosten. För att blidka konsumenterna och hävda sig i konkurrensen lovar leverantören i sin marknadsföring
Processen när ett land omfamnar demokratiska ideal efter ett auktoritärt förflutet är ofta en period fylld med glädje och firande. Men den kan även vara fylld av sorg och smärtfulla minnen från tiden före demokratins införande. Den övergångsfas som dessa länder genomgår genomsyras av dilemman då den gamla ordningens arv ska behandlas samtidigt som en ny samhällsform tar vid. För att transitionen s
Att en transition till demokrati innebär ett stabilt system är ingen självklarhet. Vissa länder lyckas inte behålla det demokratiska systemet, de misslyckas att konsolidera det. Detta problem blev påtagligt i Honduras under 2009 som efter mer än 25 år av demokratiskt styre utsattes för en statskupp. Vår uppsats syftar till att undersöka varför en demokrati misslyckas med att konsolidera sitt
