Van den Berg, J. (author)The value of models in process industries becomes apparent in practice and literature where numerous successful applications are reported. Process models are being used for optimal plant design, simulation studies, for off-line and online process optimization. For online optimization applications the computational load is a limiting factor. The...doctoral thesis 2005

Kaelen, J.W.E.N. (author)The financial crisis and the introduction of low-budget companies have brought major changes to the air freight community. Competition became stronger and cost control became more important. This led to new ways of organizing aircraft Maintenance, Repair, Overhauls and Upgrades (MRO&U), which became performance oriented. For the triad of...doctoral thesis 2014

Shariat Torbaghan, S. (author)The new energy policy of the European Union (EU) with the core objectives of competitiveness, reliability and sustainability, has driven Europe into a transition towards a low carbon & sustainable electricity supply systems. Under the new policy, the European energy systems are pursing two major objectives. First is to shift the focus from...doctoral thesis 2016

Weijs, S.V. (author)Operational management of water resources needs predictions of future behavior of water systems, to anticipate shortage or excess of water in a timely manner. Because the natural systems that are part of the hydrological cycle are complex, the predictions inevitably are subject to considerable uncertainty. Still, definitive decisions about e.g....doctoral thesis 2011

De Weerdt, E. (author)The field of global optimization has been an active one for many years. By far the most applied methods are gradient and evolutionary based algorithms. The most appearing drawback of those types of methods is that one cannot guarantee that the global solution is found within finite time. Moreover, if the global solution is found (by chance), the...doctoral thesis 2010

Van Turnhout, M. (author)A major problem in optical system design is that the optical merit function landscape is usually very complicated, especially for complex design problems where many minima are present. Finding good new local minima is then a difficult task. We show however that a certain degree of order is present in the optical design space, which is best...doctoral thesis 2009

Cong, Z. (author)Due to the rapid growth of human population, and jobs being distributed unevenly in different locations, daily commuting is required more than ever, which in its turn is creating a huge socio-economic issue: traffic congestion. In order to prevent, or at least to alleviate this problem, trafficmanagement and control is urgently required. This...doctoral thesis 2015

Fenicia, F. (author)This thesis describes an approach to model development based on the concept of iterative model improvement, which is a process where by trial and error different hypotheses of catchment behaviour are progressively tested, and the understanding of the system proceeds through a combined process of modelling and experimenting. We show a number of...doctoral thesis 2008

Van Essen, G.M. (author)The process of depleting an oil reservoir can be poured into an optimal control problem with the objective to maximize economic performance over the life of the ?eld. Despite its large potential, life-cycle optimization has not yet found its way into operational environments. The objective of this thesis is to improve operational applicability...doctoral thesis 2015

van der Helm, A.W.C. (author)Drinking water treatment plants automation becomes more sophisticated, more on-line monitoring systems become available and integration of modeling environments with control systems becomes easier. This gives possibilities for model-based optimization. In operation of drinking water treatment plants, the processes are usually optimized...doctoral thesis 2007

Chandrasekar, K. (author)Embedded systems have become an integral part of our life in the last few years in multifarious ways, be it in mobile phones, portable audio players, smart watches or even cars. Most embedded systems fall under the category of consumer electronics, such as televisions, mobile devices, and wearable electronics. With several players competing in...doctoral thesis 2014

Khalate, A.A. (author)In recent years, inkjet technology has emerged as a promising manufacturing tool. This technology has gained its popularity mainly due to the facts that it can handle diverse materials and it is a non-contact and additive process. Moreover, the inkjet technology offers low operational costs, easy scalability, digital control and low material...doctoral thesis 2013

De Wit, A.J. (author)Complex systems, such as those encountered in aerospace engineering, can typically be considered as a hierarchy of individual coupled elements. This hierarchy is reflected in the analysis techniques that are used to analyze the physcial characteristics of the system. Consequently, a hierarchy of coupled models is to be used, accounting for...doctoral thesis 2009
