Vaatstra, W. (author), Veldman, A.E.P. (author), van der Vooren, J. (author)The method of Glowinski, Periaux and Pironneau for the calculation of transonic flow, which is based on the constrained minimization of a cost function, is critically evaluated for a case in which the transonic small perturbation equation is used. The resulting minimization problem is discretized in finite element form and solved using a...report 1980

SAMID, an interactive system for aircraft drag minimization studies. Mathematical models and methodsvan den Dam, R.F. (author)An interactive computer program system has been developed that can be used in aircraft drag minimization studies. It comprises algorithms for choosing the spanwise distributions of lift, pitching moment, chord and thicknessto-chord ratio of lifting elements. The choices are optimal in that they minimize induced plus viscous drag while satisfying...report 1988

ten Dam, A.A. (author)A system of linear inhomogeneous inequalities determines a convex polyhedral set of feasible solutions. It is investigated under which conditions convex polyhedral sets can be represented also by a system that contains equalities as well as inequalities. Different representations of the same convex polyhedral set are related by elementary...report 1993

Kuiper, H. (author), van der Wees, A.J. (author), Hendriks, C.F.W. (author), Labrujère, T.E. (author)NLR participates in the ECARF (European Computation Aerodynamics Research Project) "Optimum Design" project, developing an algorithm for multi-point airfoil design. Within the ECARP project a test case has been defined for two-point design with the aid of well-specified target pressure distributions. It appears that optimization of pressure...report 1995

Blom, A.W. (author)The use of fiber-reinforced composites in aerospace structures has increased dramatically over the past decades. The high specific strength and stiffness, the tailorability, and the possibilities to integrate parts and reduce the number of fasteners give composites an advantage over metals. Automation of the production process enables large...doctoral thesis 2010

Pietersz, J.W.H. (author)Optimization is the mathematical process through which the set of conditions is obtained that produces the maximum or minimum value of a specified function. To solve different types of optimization problems several algorithms has been developed. They can be globally distinguished as deterministic or stochastic algorithms. Further on...master thesis 2010

Jalaludeen, A. (author)This master thesis work is inspired by the practical aspects of the Analytical Constant Modulus Algorithm (ACMA) proposed by Alle-Jan van der Veen and Arogyaswami Paulraj. The ACMA deals with the beamforming problem associated with constant modulus co-channel signal interference in wireless communication. Co-channel interference occur when...master thesis 2011

Stefan, R.A. (author)One of the challenges of engineering is to make the best possible use of the available resources, or in other words allocating the resources in such a way as to maximize the overall profit. In the context of networks on chip the resources are represented by the communication bandwidth and the final profit is the performance of an application...doctoral thesis 2012

La Roi, F.M. (author)The amount of travelers from and to the Dutch city Almere will grow from 40.000 back in 2009 to 100.00 in 2030. This requires intensive infrastructural improvements to the current situation of Almere. One of the main improvements of the network will be the redesign of the central station of the city. The current station is situated around a...master thesis 2012

Stano, P.M. (author)A Trailing Suction Hopper Dredger (TSHD) is a ship that excavates sediments from the sea bottom while sailing. In situ material is excavated with a special tool called the Drag-Head, then it is hydraulically transported through a pipe to the hopper where it is temporarily stored. After the dredging is completed the collected material is...doctoral thesis 2013
