  1. 1. Methods for Constrained Optimisation of Propellers

    Författare :Florian Vesting; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cavitation; constrained optimisation; genetic algorithm; propeller geometry; response surface methodology; propeller hull interaction; Kriging; artificial neural network; RANS;

    Sammanfattning : Global market development, increasing environmental concerns and incessant risingfuel prices demand for high-grade efficient propulsion systems. This puts high pressureon the propeller designer to develop well-engineered and customized propellerdesign in a short timeframe. LÄS MER

  2. 2. Marine Propeller Optimisation - Strategy and Algorithm Development

    Författare :Florian Vesting; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cavitation; artificial neural network; RANS; Kriging; potential flow; genetic algorithm; constrained optimisation; PSO; marine propeller;

    Sammanfattning : Recent trends in the shipping industry, e.g., expanded routing in ecologically sensitive areas and emission regulations, have sharpened the perception of efficient propeller designs. Currently, propeller efficiency, estimated fuel consumption and, more often, propeller-radiated noise are parameters that steer the business Zeitgeist. LÄS MER

  3. 3. Utility-based Optimisation of Resource Allocation for Wireless Networks

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Calin Curescu; Linköpings universitet.; Linköpings universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless networks; QoS; utility price-based bandwidth; allocation optimisation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : From providing only voice communications, wireless networks aim to provide a wide range of services in which soft real-time, high priority critical data, and best effort connections seamlessly integrate. Some of these applications and services have firm resource requirements in order to function properly (e.g. LÄS MER

  4. 4. Constraint Programming for Wireless Sensor Networks

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Farshid Hassani Bijarbooneh; Uppsala universitet.; Uppsala universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Constraint programming; wireless sensor networks; optimisation; macroprogramming; task mapping; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : In recent years, wireless sensor networks (WSNs) have grown rapidly and have had a substantial impact in many applications. A WSN is a network that consists of interconnected autonomous nodes that monitor physical and environmental conditions, such as temperature, humidity, pollution, etc. LÄS MER

  5. 5. Optimal Truck Scheduling Mathematical Modeling and Solution by the Column Generation Principle

    Detta är en avhandling från Matematiska institutionen

    Författare :Myrna Palmgren; Linköpings universitet.; Linköpings universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimisation; pickup and delivery problem; transportation; scheduling; column generation; integer programming; MATHEMATICS; MATEMATIK;

    Sammanfattning : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. LÄS MER
