Yu, H. (author), Mulder, J.A. (author)The CleanEra project is initiated by the Faculty of Aerospace Engineering at Delft University of Technology. Significant reduction of noise impact on perimeters of airports via arrival trajectory optimization is considered as one of the major targets of the project. In this paper, an aircraft model and its acoustic performance are introduced to...conference paper

Yu, H. (author), Mulder, J.A. (author)This work concentrates on the development of an optimization technique which is capable of minimizing the noise impact of an arriving aircraft by optimizing its flight trajectory. Actions needed from pilots to gradually establish the landing configuration are considered because it is expected that the pilot workload throughout this phase should...conference paper 2012

Yu, Z. (author), Ye, G. (author), Hunger, M. (author), Noort, R. (author)Chloride-induced corrosion of reinforced concrete is one of the main deterioration mechanisms leading to shortening of the service life of concrete structures. Therefore, assessment of the resistance of concrete to chloride ingress plays an important role in predicting the service life of such structures. The Rapid Chloride Migration (RCM) test...conference paper 2013

Yu, Z. (author), Ye, G. (author), Van Breugel, K. (author), Chen, W. (author)Deterioration of microstructure in cement concrete will cause changes in the transport properties of the concrete. Transport properties at different ages of the concrete provide information about the microstructural changes of the material. A way to measure the transport properties, i.e. the chloride diffusion coefficient, in the laboratory is...conference paper 2014

Lu, P. (author), Van Kampen, E.J. (author), Yu, B. (author)This paper presents a method for fault detection and diagnosis of actuator loss of effectiveness for a quadrotor helicopter. This paper not only considers the detection of the actuator loss of effectiveness faults, but also addresses the diagnosis of the faults. The detection and estimation of the faults are performed by the Augmented Extended...conference paper 2014

Yu, W. (author), Simao Ferreira, C.J. (author), van Kuik, G.A.M. (author)Smart rotor emerges as an innovation technique to reduce the impact of dynamic loading on wind turbines. Local movements of distributed aerodynamic devices will enhance the non-uniformity and dynamic effects of loading, which will challenge the applicability of the blade element momentum theory (BEM) for smart rotor control design due to its...conference paper 2014

Yu, C. (author), Verhaegen, M.H.G. (author)This paper studies the local identification of large-scale homogeneous systems<br/>with general network topologies. The considered local system identification problem involves unmeasurable signals between neighboring subsystems. Compared with our previous work in Yu et al. (2014) which solves the local identification of 1D homogeneous systems,...conference paper 2015

Yu, C. (author), Verhaegen, M.H.G. (author), Hansson, A (author)This paper studies the local subspace identification of 1D homogeneous networked systems. The main challenge lies at the unmeasurable interconnection signals between neighboring subsystems. Since there are many unknown inputs to the concerned local system, the corresponding identification problem is semi-blind. To cope with this problem, a...conference paper 2015

Yu, C. (author), Verhaegen, M.H.G. (author), Kovalsky, S (author), Basri, R (author)The identification of structured state-space model has been intensively studied for a long time but still has not been adequately addressed. The main challenge is that the involved estimation problem is a non-convex (or bilinear) optimization problem. This paper is devoted to developing an identification<br/>method which aims to find the global...conference paper 2015

Dabrowski, M.M. (author), Stead, D. (author), Yu, Feng (author), He, J. (author)In some of the delta cities which are the most exposed to flooding caused by climate change - like Shenzhen and Guangzhou investigated in this paper - there is surprisingly little recognition of this problem and hardly any action is taken to address it. This paper draws on the insights from these two cases to address the following research...conference paper 2016

Yu, C. (author), Hoogenboom, P.C.J. (author), Rots, J.G. (author)Sequentially linear analysis (SLA) is an alternative to the Newton-Raphson method for analyzing the nonlinear behavior of reinforced concrete and masonry structures. In this paper SLA is extended to load cases that are applied one after the other, for example first dead load and then wind load. It is shown that every nonlinear analysis step can...conference paper 2016

(author)One of the most important constraints of today’s architectures for data-intensive applications is the limited bandwidth due to the memory-processor communication bottleneck. This significantly impacts performance and energy. For instance, the energy consumption share of communication and memory<br/>access may exceed 80%. Recently, the concept of...conference paper 2016

(author)Memristor-based Computation-in-Memory is one of the emerging architectures proposed to deal with Big Data problems. The design of such architectures requires a radically new automatic design flow because the memristor is a passive device that uses resistance to encode its logic value. This paper proposes a design flow for mapping parallel...conference paper 2016

(author)Crowding in public transport can be of major influence on passengers’ travel experience and therefore affect route and mode choice. Therefore, it is important to understand how crowding in urban public transport is perceived by passengers.

Yu, C. (author), Ljung, Lennart (author), Verhaegen, M.H.G. (author)Gray-box identification is prevalent in modeling physical and networked systems. However, due to the non-convex nature of the gray-box identification problem, good initial parameter estimates are crucial for a successful application. In this paper, a new identification method is proposed by exploiting the low-rank and structured Hankel matrix...conference paper 2017

Yu, C. (author), Chen, Jie (author), Ljung, Lennart (author), Verhaegen, M.H.G. (author)The continuous-time subspace identification using state-variable filtering has been investigated for a long time. Due to the simple orthogonal basis functions that were adopted by the existing methods, the identification performance is quite sensitive to the selection of the system-dynamic parameter associated with an orthogonal basis. To...conference paper 2017
