  1. 1. Oxygen content in semi-closed rebreathing apparatuses for underwater use : Measurements and modeling

    Author : Oskar Frånberg; Ola Eiken; Mikael Gennser; Lars-Åke Brodin; John Clarke; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; rebreather; underwater breathing apparatus; unmanned testing; hyperbaric; metabolic simulator; scuba; semi-closed; Medicinsk teknologi; Medical Technology;

    Abstract : The present series of unmanned hyperbaric tests were conducted in order to investigate the oxygen fraction variability in semi-closed underwater rebreathing apparatuses. The tested rebreathers were RB80 (Halcyon dive systems, High springs, FL, USA), IS-Mix (Interspiro AB, Stockholm, Sweden), CRABE (Aqua Lung, Carros Cedex, France), and Viper+ (Cobham plc, Davenport, IA, USA).

  2. 2. The safety relevance of standardized tests for diving equipment

    Author : Mårten Silvanius; Oskar Frånberg; Greg Murphy; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; rebreather; underwater breathing apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring;

    Abstract : Vital components are more or less prone to fail in a diving apparatus. This thesis examines the performance of oxygen sensors, carbon dioxide scrubber monitoring and composite gas cylinders. READ MORE

  3. 3. Human-Machine Interface Considerations for Design and Testing in Distributed Sociotechnical Systems

    Author : Yemao Man; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Automation Bias; Human Machine Interface; Situation Awareness; Design; Maritime Transportation; Distributed Sociotechnical System; Human Factors; Decision Making;

    Abstract : The increasing concerns for safety and environmental sustainability create demands on the development of future maritime transportation strategies. One way to meet these demands is the concept of autonomous unmanned vessels for intercontinental voyages. READ MORE

  4. 4. Methods for Network Optimization and Parallel Derivative-free Optimization

    Author : Per-Magnus Olsson; Kaj Holmberg; Athanasios Migdalas; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Derivative-free; parallelization; Steiner tree; constrained shortest path; unmanned aerial vehicles;

    Abstract : This thesis is divided into two parts that each is concerned with a specific problem.The problem under consideration in the first part is to find suitable graph representations, abstractions, cost measures and algorithms for calculating placements of unmanned aerial vehicles (UAVs) such that they can keep one or several static targets under constant surveillance.

  5. 5. Aircraft Vehicle Systems Modeling and Simulation under Uncertainty

    Author : Sören Steinkellner; Petter Krus; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In aircraft development, it is crucial to understand and evaluate behavior, performance, safety and other aspects of the systems before and after they are physically available for testing. Simulation models are used to gain knowledge in order to make decisions at all development stages. READ MORE
