Sun, Yubo (author), Chen, B. (author), Zhang, Shizhe (author), Blom, Kees (author), Lukovic, M. (author), Ye, G. (author)In recent years, the rapid industrialization and urbanization led to the explosive growth of municipal solid waste incineration (MSWI) bottom ashes (BA) production. However, most of them are directly landfilled, which not only brings environmental burden but also results in loss of potential resources. Present researches have proved that MSWI BA...conference paper 2021

Chen, Anqi (author), Sun, P. (author), Kooij, Robert (author)Network recoverability refers to the ability of a network to recover to a desired performance level after suffering topological perturbations such as link failures. The minimum number of driver nodes is a typical metric to denote the network controllability. In this paper, we propose closed-form analytic approximations for the minimum number of...conference paper 2021

Dhiman, Ashish (author), Sun, P. (author), Kooij, Robert (author)This paper presents machine learning based approximations for the minimum number of driver nodes needed for structural controllability of networks under link-based random and targeted attacks. We compare our approximations with existing analytical approximations and show that our machine learning based approximations significantly outperform...conference paper 2021

Sun, Junzi (author), Hoekstra, J.M. (author)Due to the increasing demands for real-time air traffic monitoring, the 1090 megahertz radio frequency has become the most utilized communication channel for aircraft surveillance purposes. Several services are using the radio frequency at the same time, which are Mode A/C communications and Mode S communications. These different types of...conference paper 2020

Olive, Xavier (author), Sun, Junzi (author)Instability in the movement of air masses in the atmosphere can result in turbulence. Most often, turbulence causes discomfort to passengers but it can occasionally affect their safety as well. Turbulence experienced by aircraft can be difficult to predict, especially for clear air turbulence (CAT) which occurs in the absence of any visual clues...conference paper 2020

Sun, Z. (author), Kasbergen, C. (author), van Dalen, K.N. (author), Anupam, K. (author), Erkens, S. (author), Scarpas, Athanasios (author)Maintenance and rehabilitation strategies of pavements are usually made based on the results of performance evaluation. An efficient tool for pavement structural evaluation at network level is the traffic speed deflectometer (TSD) test. In order to deal with TSD measurements, this paper proposes a parameter back-calculation technique. Firstly,...conference paper 2020

Sun, B. (author), van Kampen, E. (author)Sufficient information about system dynamics and inner states is often unavailable to aerospace system controllers, which requires model-free and output feedback control techniques, respectively. This paper presents a novel self-learning control algorithm to deal with these two problems by combining the advantages of heuristic dynamic...conference paper 2020

Sun, B. (author), van Kampen, E. (author)Optimal tracking is a widely researched control problem, but the unavailability of sufficient information referring to system dynamics brings challenges. In this paper, an optimal tracking control method is proposed for an unknown launch vehicle based on the global dual heuristic programming technique. The nonlinear system dynamics is...conference paper 2020

Chen, B. (author), Sun, Yubo (author), Jacquemin, Loic (author), Zhang, Shizhe (author), Blom, Kees (author), Lukovic, M. (author), Ye, G. (author)At present, most municipal solid waste incineration (MSWI) bottom ash, as being disposed of as waste, is directly landfilled, raising concern about the environmental issue and potential loss of resources. Given that the natural raw materials used for cement production are being depleted, the recycling of MSWI bottom ash for the application as...conference paper 2019

Zhu, Fengji (author), Sun, L. (author), Zhu, K. (author), Jing, Liping (author)The educational space of Architecture faculty is used to cultivate architects. At the same time, it becomes the carrier of architectural ideas and teaching methods. The type of architecture and its spatial organization reflect the architectural education philosophy and attitude. Back in history, as early as the Renaissance, there had emerged...conference paper 2019

Sun, P. (author), Van Mieghem, P.F.A. (author), Kooij, Robert (author), He, Z. (author), Van Mieghem, Piet (author)In this paper, we propose closed-form analytic approximations for the minimum number of driver nodes needed to fully control networks, where links are removed according to both random and targeted attacks. Our approximations rely on the concept of critical links. A link is called critical if its removal increases the required number of driver...conference paper 2019

Azizi, Sadegh (author), Sun, Mingyu (author), Terzija, Vladimir (author), Popov, M. (author)Short-circuit faults occurring close to either end of a transmission line are normally cleared with some time delay by the distance relay at the opposite end of that line. The pilot relaying schemes require communication media in order to reduce this time delay. This paper presents a noncommunication method that provides high-speed distance...conference paper 2019
