Hulin, J. (author), Pavlicek, J. (author)The paper reflects on a relationship between an algorithmic and a standard (intuitive) approach to design of public space. A realized project of a plaza renovation in Czech town Vsetin is described as a study case. The paper offers an overview of benefits and drawbacks of the algorithmic approach in the described study case and it outlines more...conference paper 2013

Nicknam, M. (author), Bernal, M. (author), Haymaker, J. (author)Until recently, design teams were constrained by tools and schedule to only be able to generate a few alternatives, and analyze these from just a few perspectives. The rapid emergence of performance-based design, analysis, and optimization tools gives design teams the ability to construct and analyze far larger design spaces more quickly. This...conference paper 2013

Lendering, K. (author), Jonkman, S.N. (author), Peters, D.J. (author)New ports are mostly constructed on low lying coastal areas or in shallow coastal waters. The quay wall and terminal yard are raised to a level well above mean sea level to assure flood safety. The resulting ‘conventional terminal’ requires large volumes of good quality fill material often dredged from the sea, which is costly. The alternative...conference paper 2013

Sparing, D. (author), Goverde, R.M.P. (author), Hansen, I.A. (author)We present an optimization model which is able to generate feasible periodic timetables for networks given the line structure and the requested line frequencies, taking into account infrastructure constraints and train overtake locations. As the model uses the minimum cycle time as the objective function, the stability of the timetable is also...conference paper 2013

Ramirez-Elizondo, L.M. (author)The world’s increasing energy demand and growing environmental concerns have motivated scientists to develop new technologies and methods to make better use of the remaining resources of our planet. The main objective of this dissertation is to develop a scheduling and control tool at the district level for small-scale systems with multiple...doctoral thesis 2013

Van Nooyen, R.R.P. (author), Kolechkina, A.G. (author)In applied hydrology the question of the probability of exceeding a certain value occurs regularly. Often it is in a context where extrapolation from a relatively short time series is needed. It is well known that in its simplest form extreme value theory applies to independent identically distributed random variables. It is also well known that...conference paper 2012

Fennis, S.A.A.M. (author), Walraven, J.C. (author)The annual production of Portland cement, estimated at 3.4 billion tons in 2011, is responsible for about 7% of the total worldwide CO2-emission. To reduce this environmental impact it is important to use innovative technologies for the design of concrete structures and mixtures. In this paper, it is shown how particle packing technology can be...journal article 2012

Hamarat, C. (author), Kwakkel, J.H. (author), Pruyt, E. (author)Uncertainty manifests itself in almost every aspect of decision making. Adaptive and flexible policy design becomes crucial under uncertainty. An adaptive policy is designed to be flexible and can be adapted over time to changing circumstances and unforeseeable surprises. A crucial part of an adaptive policy is the monitoring system and...conference paper 2012

Delinchant, B. (author), Lahaye, D. (author), Wurtz, F. (author), Coulomb, J.L. (author)This paper deals with the Space Mapping optimization algorithms in general and with the Manifold Mapping technique in particular. The idea of such algorithms is to optimize a model with a minimum number of each objective function evaluations using a less accurate but faster model. In this optimization procedure, fine and coarse models interact...report 2012

Barreto Cordero, W.J. (author)Flooding in urbanized areas has become a very important issue around the world. The level of service (or performance) of urban drainage systems (UDS) degrades in time for a number of reasons. In order to maintain an acceptable performance of UDS, early rehabilitation plans must be developed and implemented. In developing countries the situation...doctoral thesis 2012
