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been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date.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.
Kompetensutveckling av personer i ledande befattningar : En studie om mentorskapets inverkan på ledarskapet
Title: Leadership development of individuals in management positions Authors: Carl Renér and Peter Simonsson Institution: Linneaus University, School of Business and Economics Program: Human Resource Management Course: Business administration ? Organization including thesis, 15 credits Supervisor: Olle Duhlin (Linneaus University, School of Business and Economics) Examiner: Mikael Lundgren (Linneaus University, School of Business and Economics) It is widely known that the role of managers may result in stress and a heavy workload. As a result of this negative effects organisations have to counteract and find new solutions and systems to facilitate and assist leaders in their work. A popular method for leadership development has come to show both in research and in practice, especially in recent years, this popular method is known as mentoring. This form of leadership development is often applied in so called mentoring programs.
Utveckling av ett lyftverktyg för skivformade produkter
Under höstterminen 2013 har Stefan Erlandsson och Louise Andersson, designingenjörsstudenter på Högskolan i Skövde, utfört ett produktutvecklingsprojekt i samarbete med entreprenören Lars Willebrand. Målsättningen för projektet var att utveckla ett lyftverktyg som ska komplettera Willebrands produktserie bestående av; travers, svängkran, plåtbyrå och lyftverktyg. Lyftverktyget ska vara anpassat för att användas i kombination med en plåtbyrå, vilket innebär att det kommer användas till att lyfta material från höga och låga höjder. Lyftverktyget måste därmed konstrueras i syfte att underlätta för användaren och undvika arbetsskador som kan uppstå vid dessa lyft. Lyftverktyget ska även kunna anpassas till kunder som endast avser att lyfta skivformade produkter i midjehöjd.Projektet inleds med en förstudie där mycket fokus läggs på ergonomi och användaren.
Det sympatiska projektet : En kvalitativ studie om hur skillnader kostrueras i mötet mellan socialtjänsten och ensamkommande barn
The aim of this study was to examine how social workers relate to unaccompanied asylum-seeking children, regarding their cultural background and potential social issues. In order to achieve a more profound and comprehensive view of the social workers views regarding the separated children, we selected to execute semi structured interviews with social workers. These interviews were aimed at those social workers who performed assessments and investigations concerning unaccompanied children. We completed nine interviews which we recorded and transcribed in a strict manor. When we analyzed the empirical material, certain themes where identified as more protuberant and thus we our selection was based on what we regarded as the most relevant topics, in accordance to the aim of the study.
Implementation av CUSUM/SPRT-algoritm för kvalitetsövervakning i realtid av robotsvetsning
Under början av 1990-talet inledde Volvo Personvagnar i Olofström en process
där övervakning av robotiserad MIG/MAG-svetsning var i fokus. Det ledde fram
till ett forskningsprojekt som resulterade i att Stefan Adolfsson, Lunds
tekniska högskola/Blekinge tekniska högskola, 1998 presenterade avhandlingen
Automatic Quality Monitoring in GMA Welding using Signal Processing Methods
[5]. I den presenterades ett SPRT-baserat övervakningskoncept för övervakning
av MIG/MAG-svetsning med kort- och spraybåge.
För att få fram ett kostnadseffektivt övervakningssystem uppkom tanken att
använda vanliga PC-datorer som plattform. De erbjuder hög beräkningskapacitet
till förhållandevis låg kostnad. Examensarbetets mål är att implementera det
SPRT-baserade övervakningskonceptet i LabVIEW på en PC och utvärdera
realtidsegenskaperna.
Sunda energieffektiva väggkonstruktioner för morgondagens flerbostadshus
Detta examensarbete har utförts vid högskoleingenjörsprogrammet Byggteknik och design vid Kungliga Tekniska högskolan och i samarbete med Ramböll Sverige. Syftet med denna rapport är att undersöka och analysera dagens ytterväggskonstruktioner för framtidens energieffektiva flerbostadshus. Ytterväggskonstruktionen som är en del i byggnadens klimatskal, har en viktig och betydelsefull funktion för att kunna klara av framtida byggnaders energikrav. För att en väggkonstruktion ska fungera finns det en rad andra påverkande faktorer som måste tas hänsyn till. Därför kommer examensarbetet att fokusera på ytterväggskonstruktioners byggfysikaliska egenskaper såsom lufttäthet, fukt, uppbyggnad och beständighet. För att kunna lösa uppgiften har vi varit i kontakt med åtta olika byggnadsentreprenörer i Stockholmsområdet och utfört studiebesök ute i produktionen. Det finns flera faktorer som styr valet av ytterväggskonstruktion för projektet och på grund av detta finns det en rad olika typer av ytterväggskonstruktioner som används i dagens byggande av flerbostadshus. I vår jämförelse mellan sex olika ytterväggskonstruktioner har vi analyserat byggfysikaliska egenskaper och produktionsmetoder utifrån samma grundparametrar.
Hälsoresan : Patienter och patientperspektiv på hälsohemmet Föllingegården 1976?1990
In the 1970s and 1980s, Sweden held about 15-20 certified health resorts that wanted to improve peoples? health with vegetarian food and alternative medicine. This essay aims to explore the popularity of health resorts through a patient?s perspective. What did the patients look for at the resort, which they could not find in the official health care? A basis for the analysis is Bonnie Blair O´Connor?s theory of Health Belief Systems.

Framtagning av nyckeltal som indikerar kvalitetsbristkostnader : Development of key performance indicators revealing the cost of poor quality
Since the 1980s, companies have taken a larger interest in quality and it´s economic impact within the company. Having the knowledge that it´s not quality that costs money, but it´s rather the lack of quality. The work immerses itself in the field of cost of poor quality and the development of key performance indicators.The thesis is performed at Bufab Holding in Värnamo. Bufab Holding is a trading company which mainly buys and sells C-parts. C-parts include fasteners, other small metal-, rubber- or plastic parts such as wires, springs and electronic fasteners.The aim of this thesis was to make a survey of the cost of poor quality and to find key performance indicators (KPI) for cost of poor quality that can be continuously monitored.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in
landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is
collected and checked.
Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator
Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
Mänsklig påverkan på mindre vattendrag i skogslandskapet : en inventering av vägtrummor och skyddszoner kring dessa i Uppsala län och norra Västmanlands län
Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be
build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this
case bridges or culverts have to be built. There are many different kinds of culverts and
depending on what type you choose and how you place the culvert, the watercourse and the
water organisms can be harmed in different ways.
