  1. 1. Efficient driving of CBTC ATO operated trains

    Författare :William Carvajal Carreño; Paloma Cucala García; Antonio Fernández-Cardador; Lennart Söder; Rafael Palacios Hielscher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; CBTC signalling system; ATO; Metro; Ecodriving; NSGA-II-F; pseudo-Pareto front; Tracking algorithm; Fuzzy parameters; Moving-block; Train Simulation.; Electrical Engineering; Elektro- och systemteknik; Energy Technology; Energiteknik; Transportvetenskap; Transport Science;

    Sammanfattning : Energy consumption reduction is one of the priorities of metro operators, due to financial cost and environmental impact. The new signalling system Communications-Based Train Control (CBTC) is being installed in new and upgraded metro lines to increase transportation capacity. LÄS MER

  3. 2. Alternative back contacts for CZTS thin film solar cells

    Författare :Sven Englund; Charlotte Platzer Björkman; Jonathan J. Scragg; Levent Gütay; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CZTS; thin film solar cells; back contacts; passivation; interface; titanium nitride; ATO; antimony-doped tin oxide; transparent back contact; CZTS; tunnfilmssolceller; bakkontakter; passivering; gränsskikt; mellanskikt; titannitrid; antimondopad tennoxid; ATO; transparent bakkontakt; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : In this thesis, alternative back contacts for Cu2ZnSnS4 (CZTS) thin film solar cells were investigated. Back contacts for two different configurations were studied, namely traditional single-junction cells with opaque back contacts and transparent back contacts for possible use in either tandem or bifacial solar cell configuration.

  4. 3. Heterogeneous Knowledge Sharing in eHealth : Modeling, Validation and Application

    Författare :Yang Guo; Guohua Bai; Eriksén Sara; Anita Mirijamdotter; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Knowledge sharing; eHealth; Activity Theory; Ontology; Decision making; Appointment scheduling;

    Sammanfattning : Knowledge sharing has become an important issue in the eHealth field for improving the quality of healthcare service. However, since eHealth subject is a multidisciplinary and cross-organizational area, knowledge sharing is a serious challenge when it comes to developing eHealth systems. LÄS MER

  5. 4. Challenges with Driverless and Unattended Train Operations

    Författare :Emil Jansson; Oskar Fröidh; Nils O.E. Olsson; Ingrid Johansson; Carl-William Palmqvist; Olov Lindfeldt; Ronghui Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway; Automatic train operation; Driverless trains; Train driver; Roles; Automation challenges; Human senses; Trackside sensors; Transportsystem; Transport Systems; Transportvetenskap; Transport Science;

    Sammanfattning : Demand for transportation continues to increase, for both freight and passenger services. One of the most energy-efficient modes of transportation is rail. One solution to increase the attractiveness of rail transport is to introduce automatic train operation (ATO) with a high grade of automation (GoA). LÄS MER

  7. 5. The Role of Production Topology in Information Based Structuring of Organizations : The design of craft-based and industrialized construction firms

    Författare :Robert Gerth; Bengt Lindberg; Mats Engwall; Lars Stehn; KTH; []
    Nyckelord :Organization structure; organization development; production system; production topology; engineer-to-order; manufacture-to-order; assembly-to-order; make-to-stock; customer-order-the-coupling-point; information processing; information storage; industrial construction; housing; cybernetic; management; SRA - Production; SRA - Produktion;

    Sammanfattning : Industrialization of construction is a business strategy to significantly improve competitiveness. However, the organization structure of the construction firms needs to support the new production system. The knowledge on why and how this business development can be accomplished is scarce, both within academia and in business practice. LÄS MER
