Design and evaluation of an AGV-system for Tetra Pack in Lund using simulation

This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Flexorafiskt tryck på wellpapp

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

?Att man tagit dom på allvar är nog det viktigaste av allt?. Folkbibliotekariers uppfattningar kring bemötande utifrån ett allmänetiskt och yrkesetiskt perspektiv

The aim of this master thesis is to study the relationship between general ethics and professional ethics, to attain an understanding of which values that are given priority in the profession of the librarian regarding personal encounter towards library users. The posed questions are: How can fundamental ethical principles be understood through the view of public librarians? How can policy documents regarding librarian ethics be understood through the view of public librarians? How can policy documents regarding librarian ethics be problematized in relation to fundamental ethical principles? We used four focus groups consisting of public librarians. Three theoretical frameworks create the base of the analysis; four fundamental ethical principles, ethical guidelines for Swedish librarians and recommendations for Swedish librarians in the reference service. Three main issues emerge in the study; equalistic personal encounter where the principle of justice is emphasized but also problematized, library users? integrity which mainly coincide with the principle of autonomy and finally the librarian?s professional role which are being defined by librarian specific competence to refrain violation of the principle of injury avoidance.

Distribution av känslig data

Information Technology (IT) makes it possible to electronically distribute data between actorswho are in geographically diverse areas. Nowadays, information is sent less frequently throughtraditional correspondence in favor of faster electronic equivalents via the internet.Despite effective IT environmentand secure encryption techniques choose some actors to sendinformation through physical delivery. This phenomenon occurs in those working withconfidential information as it is handled by a number of rules and safety regulations.Based on a set of rules and requirements, we have looked over the possibility of sending sensitiveinformation electronically over the internet. The aim was to find general guidelines for howcompanies and organizations should manage and send sensitive information over insecurenetworks. This led us to our research question: How can information be exchanged betweenactors in geographically diverse areas be categorized and encrypted so that it can be transportedover the internet without security or integrity deficiencies?To answer the question, there was a case study at a defense company.

Axle Link - en kortslutningsskyddad säker DC-överföring

Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

Biblioteken är det ingen som ifrågasätter. Om folkbibliotekens roll i kommunalpolitiken

The aim of this Master's thesis is to study what place public libraries have in local politics, particularly from the point of view of the politicians. To answer this, I have interviewed politicians, participated as a silent observer of a public debate, and studied articles on library politics in newspapers and other press. The results show that politicians in general have a positive view of libraries and good co-operation with library professionals, and that they have a fairly up-to-date view of libraries. They are, however, less interested in library issues in general, and are often complacent with the way things are already running. The newspaper studies show that library issues are usually only discussed when a specific library is somehow in danger.

Reducering av effektförbrukning i inbyggda system med Linux

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

Kartläggning och analys av tjänsteprocessen i IKEA-varuhus ur kundens perspektiv

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..

Obehörig vinst

Unjustified enrichment is used as legal basis when a part claims compensation. Unjustified enrichment can be illustrated as: (A) made a profit on someone else?s loss (B) and if the profit is"unjustified"and has"no legal basis"it shall be returned, which then make it possible for B to claim compensation from A referring to the profit. B has in this case lost something that he owns. To be able to claim A for compensation must the loss of B also be a benefit for A.

Testsystem för utredning av integrerad styrning för RC-helikopter

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.
