Yan, C. (author), Bergsma, O. (author), Koussios, S. (author), Zu, L. (author), Beukers, A. (author)The sandwich composites fuselages appear to be a promising choice for the future aircrafts because of their structural efficiency and functional integration advantages. However, the design of sandwich composites is more complex than other structures because of many involved variables. In this paper, the fuselage is designed as a sandwich...journal article 2010

Wiebenga, J.H. (author), Van den Boorgaard, A.H. (author), Klaseboer, G. (author)The coupling of finite element simulations to mathematical optimization techniques has contributed significantly to product improvements and cost reductions in the metal forming industries. The next challenge is to bridge the gap between deterministic optimization techniques and the industrial need for robustness. This paper introduces a...journal article 2012

Huibregtse, O.L. (author), Bliemer, M.C.J. (author), Hoogendoorn, S.P. (author)In this paper, approximations of optimal evacuation instructions are analyzed. The instructions, consisting of a departure time, a destination, and a route, are for the evacuation by car of a population of a region threatened by a hazard. An optimization method presented in earlier research is applied on three different hazard scenarios...journal article 2010

Lakerveld, R. (author), Benyahia, B. (author), Heider, P.L. (author), Zhang, H. (author), Braatz, R.D. (author), Barton, P.I. (author)The judicious use of buffering capacity is important in the development of future continuous pharmaceutical manufacturing processes. The potential benefits are investigated of using optimal-averaging level control for tanks that have buffering capacity for a section of a continuous pharmaceutical pilot plant involving two crystallizers, a...journal article 2013

Vermeer, K.A. (author), Lo, B. (author), Zhou, Q. (author), Vos, F.M. (author), Vossepoel, A.M. (author), Lemij, H.G. (author)Monitoring glaucoma patients and ensuring optimal treatment requires accurate and precise detection of progression. Many glaucomatous progression detection strategies may be formulated for Scanning Laser Polarimetry (SLP) data of the local nerve fiber thickness. In this paper, several strategies, all based on repeated GDx VCC SLP measurements,...journal article 2011

Verschuur, D.J. (author)Today, the problem of surface-related multiples, especially in shallow water, is not fully solved. Although surface-related multiple elimination (SRME) method has proved to be successful on a large number of data cases, the involved adaptive subtraction acts as a weak link in this methodology, where primaries can be distorted due to their...journal article 2013

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

Lu, S. (author), Lin, X. (author), Heemink, A.W. (author), Fu, G. (author), Segers, A.J. (author)Volcanic ash forecasting is a crucial tool in hazard assessment and operational volcano monitoring. Emission parameters such as plume height, total emission mass, and vertical distribution of the emission plume rate are essential and important in the implementation of volcanic ash models. Therefore, estimation of emission parameters using...journal article 2015

Van Dijk, H.A.J. (author), Damen, K. (author), Makkee, M. (author), Trapp, C. (author)In the Nuon/Vattenfall CO2 Catch-up project, a pre-combustion CO2 capture pilot plant was built and operated at the Buggenum IGCC power plant, the Netherlands. The pilot consist of sweet water-gas shift, physical CO2 absorption and CO2 compression. The technology performance was verified and validated models were obtained. This paper describes...journal article 2014

Zhu, J. (author), Zhang, W. (author), Bassir, D.H. (author)The aim of this paper is to enhance the validity of existing evolutionary topology optimization procedures. As this hard-killing scheme related to the element sensitivity values may lead to incorrect predictions of inefficient elements to be removed and the value of the objective function becomes sharply deteriorated during the iterations, a...journal article 2009

(author)Background To propel in an energy-efficient manner, handrim wheelchair users must learn to control the bimanually applied forces onto the rims, preserving both speed and direction of locomotion. Previous studies have found an increase in mechanical efficiency due to motor learning associated with changes in propulsion technique, but it is...journal article 2015

Chatterjee, Sarthak (author), Das, Subhro (author), Gonçalves Melo Pequito, S.D. (author)Solving optimization problems is a recurrent theme across different fields, including large-scale machine learning systems and deep learning. Often in practical applications, we encounter objective functions where the Hessian is ill-conditioned, which precludes us from using optimization algorithms utilizing second-order information. In this...journal article 2021

Çubukçuoglu, C. (author), Ekici, B. (author), Tasgetiren, M. Fatih (author), Sariyildiz, I.S. (author)Most of the architectural design problems are basically real-parameter optimization problems. So, any type of evolutionary and swarm algorithms can be used in this field. However, there is a little attention on using optimization methods within the computer aided design (CAD) programs. In this paper, we present Optimus, which is a new...journal article 2019
