The purposes of the study was to evaluate an effect of increasing balance task demands and visual tracking task demands, on stability and visual tracking performances, with possibility of any interaction among them. Twenty healthy participants were asked to perform various visual tracking tasks, with different attentional demands, while standing on various support surfaces. Two-way analysis of variance (ANOVA) with repeated measure design was performed to estimate significant effect. Support surface properties showed significant effects on stability measures but no significant effect on visual tracking performances were noticed. Significant effect of increasing visual tracking task demands on visual tracking performances were found. However, increasing visual tracking task demand did not show any significant effect on stability measures. Significant interaction effect was also found between surface properties and visual tracking task demands for stability measures. In conclusion, increasing balance demands effect stability and increasing visual tracking demands effect visual tracking performances.

The focus of this thesis is the Visio Baronti (VB), an account of a seventh-century monk's journey to the other world. This text serves as a metaphoric fulcrum to support a more extensive study of early medieval conceptions of the other world and the historical context in which visionary accounts were produced. Chapter 1 contains an introduction to ideas of the other world, a survey of types of visionary experiences, their uses, imitations and historiographical responses to them. Chapter 2 focuses on medieval and modern responses to visions. This chapter includes a survey of the terminology for dreams and visions found in theoretical writings, compares dream theory with otherworld visions and identifies medieval methods of determining the validity of a visionary experience. Chapter 3 investigates the manuscript tradition of the VB, in order to illuminate medieval receptions and treatments of this text. Because the text appears unusual for the seventh century, chapter 4 provides an analysis of the grounds for dating the VB to the seventh century, while chapter 5 treats the VB in its seventh-century monastic context and assesses what influences shaped this text. Chapter 6 compares Barontus's vision with ninth-century visions and other Carolingian writings to consider Carolingian interest in the VB in light of their contributions to the genre. Chapter 7 examines the artistic response to this text through an examination of the illustrations which accompany the text in the ninth-century St Petersburg manuscript. A brief conclusion to this study follows.

Examensarbetet är utfört i samarbete med ett företag. Målen är att ta fram en användarvänlig digital modell av verkstaden, arbeta fram tre förbättringsförslag på layouter med omplaceringar av utrustning och maskiner. Förbättringar skall föreslås inom hållbarhetsaspektern aekonomi, social och miljö. För att nå målet att skapa en digital verkstadslayout har projektgruppen mätt upp hela fabriken med hjälp av laseravståndsmätare, då exakta ritningar saknades. Vid besök i fabriken kunde all nödvändig information mätas upp för skapandet av den digitala fabriksmodellen. Besöken vid fabriken har gett inspiration till nya layoutförslag och förbättringar. Observationer och intervjuer med personal har gjorts. Produktionsflöden och processer för de största produktgrupperna har kartlagts. Litteratur som berör produktionsteknik, arbetsmiljö och andra relevanta områden har studerats. Projektgruppen har utfört ljusmätning i fabriken. Belysningen var tillfredställande. Förslag på bullerdämpande åtgärder har framarbetats. Den digitala fabriksmodellen har skapats i programmet Microsoft Visio efter urval mot kravspecifikation från företaget samt KTHs programvaruutbud. De tre layoutförslag som tagits fram har värderats och ställts mot varandra i ett värderingsschema för att kunna bestämma ett slutgiltigt förslag till ny verkstadslayout. Layoutförslag 2 fick högst poäng i utvärderingen där lägre kostnader, förbättrat flöde samt förbättrad tillgång för truck var de bidragande faktorerna. Förslaget innebär kort att centerlesslipmaskinerna flyttas till den yta som renoverats, en svarv flyttas för att ge plats åt truckar, stationen för kvalitetskontroll flyttas och mer plats frigörs för lastpallar. / This thesis is done in collaboration with a company. The goals are to develop a userfriendly digital model of the workshop, to suggest three improved layout proposals with repositioning of equipment and machines. Improvements should also be proposed in the sustainability aspects of economy, social and environmental. To achieve the goal of creating a digital workshop layout, the project team measured the entire factory with the aid of laser rangefinders, because exact drawings were missing. When visiting the factory, all the necessary information could be measured for the creation of the digital factory model. The visits to the factory have provided inspiration for new layout suggestions and improvements. Observations and interviews with staff have been made. Production flows and processes for the largest product groups have been mapped. Literature relating to production technology, work environment and other relevant areas has been studied. The project group has carried out light measurement in the factory. The lighting was satisfactory. Noise reduction measures have been proposed. The digital factory model has been created in the Microsoft Visio software after evaluation based on company specification and KTH's software. The three layout proposals that have been developed have been evaluated and compared to each other in an evaluationscheme to determine a final proposal for a new workshop layout. Layout proposal 2 received the highest score in the evaluation, where lower costs, improved flow and improved access for forklifts were the contributing factors. In short the proposal suggest that the centerless grinders are moved to the area that has been renovated, a lathe is moved to accommodate forklifts, the quality control station is movedand more space is freed up for pallets.

<p>Alltid har mjukvaruföretagen varit intresserade av att bedriva applikationsutvecklingen så effektiv och lönsam som möjligt. För detta avseende använder många utav dem olika CASE-verktyg. Ett sådant CASE-verktyg är VISIO 2000 Enterprise. CASE-verktyg kan t ex användas för att genomföra transformeringar mellan modeller och koder. Denna möjlighet underlättar applikationsutvecklingen, men tyvär kan sådana transformeringar medföra eventuella förluster av data och leda till att eventuella semantiska förluster uppstår. Dessa förluster kan innebära att den representerade informationen i modeller och koder inte är det samma efter en transformation. Därför är det intressant att undersöka hur bra ett CASE-verktyg klarar av detta innan det kan avändas som stöd vid applikationsutveckling. I denna rapport undersöks genereringsmöjligheterna i CASE-verktyget VISIO 2000 Enterprise samt de eventuella semantiska förluster som kan uppstå vid transformationer mellan modeller och koder via CASE-verktyget. Olika tester innehållande transformationer mellan modeller och koder som representerar grundläggande relationer mellan olika klasser har genomförts för att undersöka förluster av relationer mellan klasser samt förluster av relationsnamn, medlemsfunktioner och medlemsvariabler i klasserna och koden. Utifrån testresultaten kan slutsats dras att VISIO kan vara bra använda vid applikationsutveckling när det gäller transformationer av modell till kod men inte tvärtom.</p>

Η παρούσα διπλωματική εργασία εκπονήθηκε στο Εργαστήριο Ασύρματης Τηλεπικοινωνίας του τμήματος Ηλεκτρολόγων Μηχανικών και Τεχνολογίας Υπολογιστών. Ο στόχος της εργασίας αυτής ήταν η μελέτη της μετάδοσης κωδικοποιημένου βίντεο H.264/AVC στο δίκτυο WiMAX με βάση τη χρήση τριών σχημάτων διαμόρφωσης φυσικού επιπέδου του σήματος βίντεο. Λαμβάνοντας υπόψιν την τεράστια εξέλιξη των ασύρματων δικτύων, αλλά και των συσκευών που μπορούν να υποστηρίξουν πολυμεσικές εφαρμογές, καθιστούν τελικά τη μετάδοση βίντεο μια από τις σημαντικότερες προκλήσεις και ένα δημοφιλή ερευνητικό προσανατολισμό. Σημαντικό ρόλο στη μετάδοση του βίντεο διαδραματίζουν οι παράμετροι που διασφαλίζουν την Ποιότητα των Παρεχόμενων Υπηρεσιών, όπως το εύρος ζώνης, η καθυστέρηση, η διακύμανση της καθυστέρησης και φυσικά η απώλεια πακέτων. Ωστόσο, σε ένα δίκτυο υπάρχουν ποικίλλες παράμετροι που πρέπει να λαμβάνονται υπόψιν κατά τη μετάδοση πολυμεσικής πληροφορίας και στην παρούσα εργασία έγινε μια προσπάθεια να εξεταστεί το θέμα υπό το πρίσμα της διαμόρφωσης φυσικού επιπέδου. Το εργαλείο που χρησιμοποιήθηκε για τη μελέτη αυτή, είναι ο εξομοιωτής δικτύων NS-2, η έκδοση ns-2.29. Για την εξαγωγή των γραφικών παραστάσεων χρησιμοποιήθηκε το Matlab R2009b, ενώ για την εξαγωγή των σχημάτων το Microsoft Office Visio 2010. / This diploma thesis was developed at the Laboratory of Wireless Communications, at the Department of Electrical and Computer Engineering. The objective of this work was to study the transmission of the encoded video H.264/AVC through its transmission over WiMAX network based on the use of three physical layer modulation schemes of the video signal. Considering the tremendous evolution of wireless networks and the fact that modern devices can support multimedia applications, it cannot be denied that video broadcasting is of major importance and constitutes a great challenge for the engineers for further research. Parameters that ensure quality of service, such as bandwidth, delay, delay variation and of course packet loss, play dominant role in the optimization of video transmission. However, in a network, there are various parameters that should be taken into consideration when transmitting multimedia data. The tool used for this study is the network simulator NS-2, the version ns-2.29. In order to export the graphics the software that was used is Matlab R2009b, while the Microsoft Office Visio 2010 software was used to export the figures.
