  2. 21. Enhancing Aircraft Conceptual Design using Multidisciplinary Optimization

    Author : Daniel Raymer; KTH; []
    Keywords : aircraft design MDO optimization fighter UAV transport;

    Abstract : Research into the improvement of the Aircraft ConceptualDesign process by the application of MultidisciplinaryOptimization (MDO) is presented. Aircraft conceptual designanalysis codes were incorporated into a variety of optimizationmethods including Orthogonal Steepest Descent (full-factorialstepping search), Monte Carlo, a mutation-based EvolutionaryAlgorithm, and three variants of the Genetic Algorithm withnumerous options.

  4. 22. Towards synthesis for nitrogen fertilisation using a decision support system

    Author : Sandra Wolters; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nitrogen (N) fertilisation in crops can be made more efficient by moving from uniform application to meeting variable crop requirements within fields. Within field variable rate N fertilisation of winter wheat (Triticum aestivum L.) is practically feasible using information from web-based decision support systems (DSS). READ MORE

  5. 23. Modelling and Implementation of a vision system for embedded systems

    Author : Per Andersson; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Today more and more functionality is included in embedded systems, resulting in an increased system complexity. existing design methodologies and design tools are not adequate to deal with this increase in complexity. To overcome these limitations application specific design solutions are more common. READ MORE

  6. 24. Fuzzy gain scheduled visual servoing for an unmanned helicopter

    Author : Bourhane Kadmiry; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : The overall objective of the Wallenberg Laboratory for Information Technology and Autonomous Systems (WITAS) at Linkoping University is the development of an intelligent command and control system, containing active-vision sensors, which supports the operation of an unmanned air vehicle (UAV). One of the UA V platforms of choice is the R5O unmanned helicopter, by Yamaha. READ MORE

  7. 25. Methods for Network Optimization and Parallel Derivative-free Optimization

    Author : Per-Magnus Olsson; Kaj Holmberg; Athanasios Migdalas; Linköpings universitet; []
    Keywords : 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.
