Wensveen, M.H. (author)Optimistic Planning is a model-based online planning algorithm that guarantees near-optimal actions for the control arbitrarily nonlinear systems. Planning algorithms aim to find optimal actions by starting from the current state and developing a tree representation of sequences of actions and resulting states, using a model to simulate state...master thesis 2014

Dobrochinski, J.P.H. (author)Large capital and maintenance dredging operations are required to ensure the accessibility of many ports. The expenses associated with the dredging operations can have a significant impact on the finances of these ports. Therefore, considerable attention to the design of the width and depth aspects of access channels is justifiable. This study...master thesis 2014

Qiu, Y. (author), Van Gijzen, M.B. (author), Van Wingerden, J.W. (author), Verhaegen, M. (author), Vuik, C. (author)In this paper, we consider preconditioning for PDE-constrained optimization problems. The underlying problems yield a linear saddle-point system. We study a class of preconditioners based on multilevel sequentially semiseparable (MSSS) matrix computations. The novel global preconditioner is to make use of the global structure of the saddle-point...report 2014

Smidt, D.M. (author)This research is twofold. Firstly it treats the complexity of design using a computational intelligent method to achieve, with regard to a limited set of goals, high performing designs. Secondly, an architectural and structural challenge to conceptually design a freeform roof framework, which integrates structural rigidity and non-standard...master thesis 2014

Bischiniotis, K. (author)This research follows a fully probabilistic approach in order to estimate the optimal design for a river dike cross-section, taking into account the investment costs. From the theory studied, the failure mechanisms that contribute most to the failure of river dikes are identified. These are overflowing, wave overtopping, piping and inner slope...master thesis 2014

De Jong, P.M.A. (author)During today’s aircraft descents, Air Traf?c Control (ATC) commands aircraft to descend to specific altitudes and directions to maintain separation and spacing from other aircraft. When the aircraft is instructed to maintain an intermediate descent altitude, it requires engine thrust to maintain speed, leading to increased fuel burn and noise...doctoral thesis 2014

Chang, C. (author), Borgart, A. (author), Chen, A. (author), Hendriks, M.A.N. (author)This paper proposes an efficient and reliable topology optimization method that can obtain a black and white solution with a low objective function value within a few tens of iterations. First of all, a transformation of variables technique is adopted to eliminate the constraints on the design variables. After that, the optimization problem is...journal article 2014

Alim, M. (author)Constrained optimization is the process of optimizing an objective function with respect to some variables in the presence of constraints on those variables themselves or on some function of those variables. This thesis focused on using the Ensemble Optimization method to improve the NPV (Net Present Value) as the objective function of...master thesis 2013

Spiridon, V.L. (author)In recent years, there is an increasing interest in the scientific community for development of algorithms targeting large-scale networks. In addition to their sheer size, these networks also exhibit various topology dynamics -- nodes join and exit at high rates (churn), are mobile and are not always reliable. Such extreme properties make...master thesis 2013
