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been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date.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.

Statistik, nyckeltal och mätmetoder ? Vad ger de för bild av bibliotekens verksamhet?

The aim of this Bachelor´s thesis is to investigate how library statistics, performance measurement and indicators represent the modern public library activity. During the last decades the public library has gone through a lot of changes. Information overall has increased and new technology has been introduced into the library. This new development has had effects on the library users. The statistics reported to the Statens kulturråd (National Arts Council) has not changed in the same way.

This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.

Utbildningskapital, ekonomiskt kapital och utbildningsstrategi : En deskriptiv utbildningssociologisk studie om gymnasieleverna som antagits till det naturvetenskapliga programmet i Botkyrka kommun

Secondary schools have for decades debated whether they promote social reproduction which is considered to generate the homogeneous student compositions. The gap between the academic programs and vocational education programs is considered to increase. What in recent years has appeared in research is that the gap is increasing most tend to be in the specific academic program, particularly in science. This paper's intention is to describe the science program at a local level and the pupils who were admitted to the science program autumn 2009 on the basis of an educational sociological perspective. The survey consisted of a census in which all students were given the opportunity to answer a questionnaire.

Usually it is in the description of what is to be acquired as the information is incomplete, but also in knowing when Quality Control-functions (QC) is supposed to be used.The aim of this work is to describe and analyse the material acquisition process.

Barns upplevelser av högläsning och boksamtal

What drove me to write this paper is the will to  examine if there is a philosophically and scientifically viable  alternative foundation for an objective morality other than what we like to refer to as "God". The  American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that  science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a scientific ground.

Från föhn till feu! : Esrange och den norrländska rymdverksamhetens tillkomsthistoria från sekelskiftet 1900 till 1966

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Att skildra sin historia - En diskursanalys av franska politikers bild av Frankrikes roll som kolonisatör sett ur ett postkolonialteoretiskt och mångkulturellt perspektiv

The aftermath of colonization, culture diversity and the recognition of the ownidentity - living in a country which has the role of a former colonizer has got consequences in the multicultural French society. These consequences can be seen studying the politics, the education and the history of that country. In this bachelorthesis I discuss the aftermath of French colonization with a focus on how the French cultural identity can be explained in defining colonialism in French lawmaking. The aim is to understand the definition of the own cultural identity from a postcolonial perspective and what meaning the multicultural society has for this definition. This is an issue which can be seen in politics as well as ineveryday life, and to make an understanding of it, I study how French politicians are representing their country's role as a former colonizer in a postcolonial era.

Science fiction i spelutveckling

Detta kandidatarbete undersöker science fiction, en av de större och vanligast använda genrerna inom medier såsom spel, film och litteratur, genom att studera dess undergrupper, de så kallade subgenrerna. Dessa är specialiserade versioner av genren i fråga och använder den inom vissa förutsatta ramar, exempelvis hur samhället ser ut eller vilken typ av teknologi det huvudsakliga fokuset kretsar runt. Genom att studera hur subgenrer är beskrivna i The Encyclopedia of Science Fiction kan man avgöra att de består av sex punkter: plats, tidsperiod, karaktärer, teknologi, narrativ och visuell estetik. Dessa punkter har använts som ramverk för att utveckla en ny subgenre; Mystech, där scenarier utspelar sig i vad som kan ses som en typisk fantasyvärld med magi och monster, men där dessa egentligen bara är teknologi majoriteten av de påverkade inte förstår sig på. För att demonstrera Mystech har två olika miljöer utvecklats, både i bild och skriven form. Dessa är två mycket olika skådeplatser för scenarier att berättas i men som trots sina olikheter har nog med faktorer gemensamt för att kunna klassificeras som delar av samma subgenre..

Production system mapping for product design

Detta examensarbete är resultatet av en utredning av produktionsbegränsningar och produktutveckling på Volvo Construction Equipment AB Component Division i Eskilstuna. Produktionssystemet på Volvo CE genomgår en stor förändring då det går från att fungera som en funktionell verkstad till att bli flödesinriktat. Detta gör att helt nya krav ställs på produkternas konstruktion och utformning. Det är nu inte möjligt att anpassa maskinerna eller operationsföljderna efter artikeln i samma utsträckning som tidigare, man kommer att vara tvungen att anpassa artiklarna efter produktionslinan. Därav har en litteraturstudie inom Concurrent Engineering gjorts som belyser hur man bör jobba som organisation och vilka verktyg man har till sitt förfogande, för att utveckla produktionsvänliga produkter.

Utveckling av en Multi-Zonsmodell för NOx Bildning i Diesel Motorer

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Vetenskapsteoretiska och metodologiska perspektiv på tidsgeografiska visualiseringsmodeller. -En fallstudie i samhällsvetenskaplig visualisering

In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.

Chinese Remainder Theorem

Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.
