Separeringsmodul
In cooperation with the Gislaved company Lerocon AB [1], a separation module wasdesigned as a further supplement to the Module System. The aim of theprojectimplementation was that the separation module could be flexible enough to feed themetal pieces, screws, nuts and other items with large variations of size, appearance andmaterial composition. The module should also be cost effective to manufacture.A separation module is a design which is ment to streamline the work in industries withautomation of the lineoperations. The module feeds the details such as screws, nuts, washersand pieces of metal in a continuous flow in which traps separate the details from each other.Traps may vary depending on the purpose and of the details that are fed. Perhaps it isimportant for the user that the detail-orientation is right after the separation module, whichmeans that all the pieces witch aren´t are fed back in return.For companies and industries in lineoperations that can be made more efficient withautomation, are production flow an important watchword.
Provmetod för olje- och partikelöverdrag från kompressor till tryckluftssystem
Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.
Områdessökning i geografiskt associerad data
This thesis considers the problems associated with searches in insufficiently geographically tagged data. The thesis was carried out at Booli Search Technologies AB, a company developing a search engine for the Swedish real estate market.The aim of the thesis is to identify some areas of possible improvements of the company?s existing technical platform, perform a benchmarking among similar services, suggest possible solutions and lastly, build a prototype from one of the suggested solutions.The thesis starts out with defining the problems that the search engine faces: some areas are not possible to perform searches on, the users are not presented with the full search result that they expect, some results are placed incorrectly on the map associated with the search results and results are also not described with enough geographical information. These problems are due to the fact that the data retrieved at the indexing stage in the company?s information retrieval process are insufficient and incomplete.As a result of a benchmarking process and after discussing the results, severalinteresting solutions were identified.
Personuppgifteshantering och identifiering inom myndighet, skola och förtag
The authors of this thesis have studied the handling of personal information in various kinds of organizations, because the perception is that the knowledge in this area is weak relative to the weight of the subject.The purpose of this paper has been partly to shed light on how knowledge of this area in the organizations that we have visited during the study but also to answer questions about handling, knowledge and security, and identification of individuals in different systems. What kind of problems the processing of these data creates and why these problems occur.In the beginning of our study we understood the importance of using the correct identifier and therefore chose also to examine what the various identifiers used by the organizations and why they chose these particular identifiers.In the qualitative analysis, Datainspektionen´s general rules and advice has been used as a basis together with the laws applicable to the organizations to get a good picture of how management of personal information is in these organizations.What we have found in this paper is that knowledge about how personal data is handled and what laws and rules are saying is very much dependent on how central the information is to these organization's activities. The police use so many different types of records for their organization to function well and they have very good knowledge of laws and regulations. In contrast, schools that do not handle as much of personal data themselves nor have the same knowledge among staff and do not have enough resources to cope with keeping the same knowledge base as the police. This is something that applies to all types of handling, depending on how important the information is for the organization, the better the security and knowledge in handling the data is..
Påverkas mosippa (Pulsatilla vernalis) negativt av igenväxning?
Pulsatilla vernalis is one of several endangered plant species that benefit from wildfires and small scale disturbance events that repel competing vegetation and create open patches in the vegetation cover. Previous studies argue that Pulsatilla vernalis is decreasing in numbers due to vegetation changes associated with the decrease in wildfires, forest grazing and changes in forest management. In this study, 17 populations of P. vernalis were inventoried in order to examine if soil and/or vegetation structures affect the population structure of P. vernalis (i.e.
Utveckling av instyrningsfunktionen hos ett dockningsinterface
In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.
En jämförelse mellan vakuumisolering och traditionell isolering
The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years.

Från Monopol Till Konkurrens : Telias hantering av den ökande konkurrensen genom förändrade marknadsföringsstrategier
The Swedish telecommunication market was prior to the official deregulation 1975 characterized by Telia?s former monopoly position. This thesis studies how the deregulation of the market, and the thereby increasing competition, has affected Telia and how it has influenced Telia?s marketing strategies.The theoretical framework, from which the conclusions will be made, is a combination of the theory about strategic learning behaviours by Slater et al, and Grönroos? theory about a marketing continuum. The empirical work material is the result from two interviews with former key figures at Telia, and a briefing of Telia?s annual report between the years 1993 and 2006.Research findings indicate that Telia has gone from being product oriented with a strong technical focus, to becoming gradually more market oriented with competition orientation but foremost customer orientation as their most distinguished learning behaviours.

Målet med examensarbetet är en datamodell som ska kunna följas vid uppbyggnaden av MD N:s databas för metadata. Målet är även en modell som ska kunna följas vid omstrukturering av MD N:s geografiska grunddata.
Rening av avloppsvatten efter skärprocess
ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB
Flexible Automation with high-pressure intensifier/pumping technology from
Ingersoll-Rand to provide and continue to develop innovative waterjet cutting
systems for global markets.
The purpose of this assignment is to develop a process water purifier. The
purifier should be applicable as an option to ABB I-R?s production cell
Cutting-Box.
At first hand the process water should be purified well enough to let out in
the municipal sewage system, but the ultimate solution is purifying the process
water to the range that recycling is possible.
When investigating the different principle of purifying water, a research of
different products and their manufactories was done.
These different products were compared and the principle of filtration was the
most applicable, as most of the products were designed for far larger
applications.
As the process water contains quite large amount of particles, it is necessary
to perform the filtration in different steps.
The process water purifier is therefore composed of a module of coarse
filtration and one of micro filtration.
In the module of coarse filtration the mainly amount of fibres and particles
are eliminated. They are kept back in the container unit with the larger
fragments and dumped with these when the container is emptied.
In the module of micro filtration the filtration is performed in two steps.
In the first step particles larger than 50?m are eliminated, in the second step
the micro filter is setting the range of purifying, in this case 10?m.

Comparison between anesthesia with sufentanil-midazolam and sevoflurane in medetomidine premedicated rabbits undergoing ovariohysterectomy
Rabbits carry a high risk of anesthesia related death. This study was part of a project to develop a form of total intravenous anesthesia (TIVA) with minimal effects on cardiac, respiratory and metabolic parameters. In the study, TIVA with sufentanil and midazolam (group TIVA, n=9) was compared with inhalation anesthesia with sevoflurane (group SEVO, n=9) in female rabbits undergoing surgery (ovariehysterectomi). All rabbits were pre-medicated with medetomidin and carprofen before anesthesia induction. Anesthesia was induced with TIVA (2.3 ?g/ ml sufentanil, 0.45 mg/ ml midazolam) at a rate of 4 ml/ kg/ h and the mean induction dose was 0.4 ?g/ kg of sufentanil and 0.1mg/ kg of midazolam.
