  1. 46. Reducing Alkali Chloride-Induced High Temperature Corrosion by Sulphur Containing Additives – A Combined Laboratory and Field Study

    Författare :Sofia Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sulphur; Stainless Steels; Additives; Biomass; Waste; High Temperature Corrosion; Alkali Chlorides; Co-combustion;

    Sammanfattning : In order to achieve a more sustainable society renewable fuels such as biomass and waste are attractive alternatives to fossil fuels for power production. However, fireside corrosion is a serious concern in boilers combusting biomass or waste. The high corrosion rates are often linked to large amounts of alkali chlorides in the flue gas. LÄS MER

  3. 47. Opportunistic Networking : Congestion, Transfer Ordering and Resilience

    Författare :Fredrik Bjurefors; Per Gunningberg; Christian Rohner; Mario Gerla; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Opportunistic Networking; Congestion; Transfer Ordering; Resilience; Testbed; WISENET; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Opportunistic networks are constructed by devices carried by people and vehicles. The devices use short range radio to communicate. Since the network is mobile and often sparse in terms of node contacts, nodes store messages in their buffers, carrying them, and forwarding them upon node encounters. LÄS MER

  4. 48. High Temperature Corrosion Behavior in Biomass- and Waste-Fired Boilers - Insights into catastrophic corrosion and corrosion mitigation techniques

    Författare :Julien Phother Simon; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D tomography; TEM; Sulfur Recirculation; Waste; High-temperature corrosion; Biomass; Coatings; Stainless steel; Ni-based alloys; Deposits; KCl-induced corrosion;

    Sammanfattning : Carbon dioxide is contributing to the greenhouse effect and a significant part comes from the use of fossil fuels. Utilizing more renewable fuels is therefore a solution to decrease the net release of CO2 emissions to the atmosphere. LÄS MER

  5. 49. Attacking predators and fleeing prey : detection, escape and targeting behaviour in birds

    Författare :Ulrika Kaby; Innes Cuthill; Stockholms universitet; []
    Nyckelord :zoology; ethology; birds; animal behaviour;

    Sammanfattning : The aim of this thesis is to further our understanding of predator and prey behaviour and decision making in different attack situations. The thesis deals with escape strategies, predator detection ability and prey targeting behaviour. LÄS MER

  7. 50. Security-Aware Design of Cyber-Physical Systems for Control Applications

    Författare :Rouhollah Mahfouzi; Petru Ion Eles; Zebo Peng; Samarjit Chakraborty; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With cyber-physical systems opening to the outside world, security can no longer be considered a secondary issue. In this work, we focus on security threats to control applications in cyber-physical systems. LÄS MER
