Lu, S. (author), Li, J. (author), Van Zuylen, H. (author)Different aspects of the traffic control system in the CBD of Changsha have been evaluated. A general issue is the safety conditions, which are evaluated qualitatively. The second issue is the low saturation flow observed on the intersections, that appear to be 20 to 30% lower than the ones in comparable situations in Europe or North America....journal article 2012

Van Zuylen, H.J. (author), Lu, S. (author), Li, J. (author), Yusen, C. (author)Traffic management in cities with congestion is a big challenge with still unused opportunities. Intersection control is a corner stone but this should be done in an area-wide context. The dominant traffic process on urban roads is the traffic flow on the intersections. Spill back is a most important cause of malfunctioning networks. The...conference paper 2014

Zheng, Fangfang (author), Li, Jie (author), van Zuylen, H.J. (author), Lu, Chao (author)Fuel consumption and atmospheric pollution emissions of vehicles depend on driving conditions, the characteristics of the driver and the car. The influence of driving style on the environmental aspects of a car journey has been investigated.

Lu, Dan (author), Yang, Shunkun (author), Zhang, Jiaquan (author), Wang, H. (author), Li, Daqing (author)Epidemic propagation on complex networks has been widely investigated, mostly with invariant parameters. However, the process of epidemic propagation is not always constant. Epidemics can be affected by various perturbations and may bounce back to its original state, which is considered resilient. Here, we study the resilience of epidemics on...journal article 2017

Li, Nana (author), Jia, Li (author), Lu, Jing (author), Menenti, M. (author), Zhou, J. (author)The regional surface soil heat flux (G0) estimation is very important for the large-scale land surface process modeling. However, most of the regional G0 estimation methods are based on the empirical relationship between G0 and the net radiation flux. A physical model based on harmonic analysis was improved (referred to as "HM model") and...journal article 2017

Zheng, F. (author), Liu, Xiaobo (author), van Zuylen, H.J. (author), Li, Jie (author), Lu, Chao (author)The importance of travel time reliability in traffic management, control, and network design has received a lot of attention in the past decade. In this paper, a network travel time distribution model based on the Johnson curve system is proposed. The model is applied to field travel time data collected by Automated Number Plate Recognition ...journal article 2017

(author)Purpose: Variations in the radiosensitivity of tumor cells within and between tumors impact tumor response to radiation, including the dose required to achieve permanent local tumor control. The increased expression of DNA-PKcs, a key component of a major DNA damage repair pathway in tumors treated by radiation, suggests that DNA-PKcs– dependent...journal article 2018

Gao, Mingyuan (author), Li, Yunwu (author), Lu, Jun (author), Wang, Yifeng (author), Wang, Ping (author), Wang, L. (author)The goal of this study is to develop a vibration-based electromagnetic energy harvesting prototype that provides power to rail-side monitoring equipment and sensors by collecting wheel-rail vibration energy when the train travels. This technology helps power rail–side equipment in off-grid and remote areas. This article introduces the...journal article 2018

Zheng, Fangfang (author), Li, Jie (author), van Zuylen, H.J. (author), Lu, Chao (author)All drivers have individual ways of driving. Still, there are groups of drivers with more or less similar characteristics. In this research, 28 drivers from Chengdu city (P.R. China) participated in an experiment where car following behaviour was measured with GPS devices. In every measured trip there was a leading and following vehicle both...journal article 2019

Lu, T. (author), Li, Z. (author), van Breugel, K. (author)In recent decades, several simulation models have been proposed to predict autogenous shrinkage of cementitious systems. In most of these models, however, only the elastic deformation caused by self-desiccation of the hydrating cement paste is considered. In fact, cement paste is not an ideal elastic material. Also the time-dependent...journal article 2020
