Reference-free time-based localization for an asynchronous target

Wang, Y. (author), Leus, G.J.T. (author)

Low-complexity least-squares (LS) estimators based on time-of-arrival (TOA) or time-difference-of-arrival (TDOA) measurements have been developed to locate a target node with the help of anchors (nodes with known positions). They require to select a reference anchor in order to cancel nuisance parameters or relax stringent synchronization...

Wang, H. (author), Tao, Y. (author), Temudo, M. (author), Schooneveld, M. (author), Bijl, H. (author), Ren, N. (author), Wolf, M. (author), Heine, C. (author), Foerster, A. (author), Pelenc, V. (author), Kloek, J. (author), Van Lier, J.B. (author), De Kreuk, M.K. (author)

Background Solid bio-wastes (or organic residues) are worldwide produced in high amount and increasingly considered bioenergy containers rather than waste products. A complete bioprocess from recalcitrant solid wastes to methane (SW2M) via anaerobic digestion (AD) is believed to be a sustainable way to utilize solid bio-wastes. However, the...

DNSSEC offers protection against spoofing of DNS data by providing origin authentication, ensuring data integrity and authentication of non-existence by using public-key cryptography. Although the relevance of securing a technology as crucial to the Internet as DNS is obvious, the DNSSEC implementation increases the complexity of the deployed...

Change analysis in structural laser scanning point clouds: The baseline method

Shen, Y. (author), Lindenbergh, R.C. (author), Wang, J. (author)

A method is introduced for detecting changes from point clouds that avoids registration. For many applications, changes are detected between two scans of the same scene obtained at different times. Traditionally, these scans are aligned to a common coordinate system having the disadvantage that this registration step introduces additional...

Integration of Traffic Information into the Path Planning among Moving Obstacles

Wang, Z. (author), Steenbruggen, John (author), Zlatanova, S. (author)

This paper investigates the integration of traffic information (TI) into the routing in the presence of moving obstacles. When traffic accidents occur, the incidents could generate different kinds of hazards (e.g., toxic plumes), which make certain parts of the road network inaccessible. On the other hand, the first responders, who are...

Analysis of Bridge Transition Zones in Railways Considering the Moisture Condition of the Ballast and Subballast

Wang, Haoyu (author), Silvast, Mika (author), Markine, V.L. (author), Wiljanen, Bruce (author)

Transition zones in railway tracks are the locations with considerable changes in vertical support structures, e.g., near bridges. Due to possible water flow constrictions in transition zone structures, there is frequently an increased moisture level in the ballast/subballast layers, which is a potential source of track degradation. This paper...

Data-driven hazardous gas dispersion modeling using the integration of particle filtering and error propagation detection

Zhu, Zhengqiu (author), Qiu, S. (author), Chen, Bin (author), Wang, Rongxiao (author), Qiu, Xiaogang (author)

The accurate prediction of hazardous gas dispersion process is essential to air quality monitoring and the emergency management of contaminant gas leakage incidents in a chemical cluster. Conventional Gaussian-based dispersion models can seldom give accurate predictions due to inaccurate input parameters and the computational errors. In order...

Structural health monitoring of railway transition zones using satellite radar data

Wang, Haoyu (author), Chang, L. (author), Markine, V.L. (author)

Transition zones in railway tracks are locationswith considerable changes in the rail-supporting structure. Typically, they are located near engineering structures, such as bridges, culverts and tunnels. In such locations, severe differential settlements often occur due to the different material properties and structure behavior. Without...

Bromate reduction by iron(II) during managed aquifer recharge: A laboratory-scale study

Wang, F. (author), Salgado Ismodes, V.A. (author), van der Hoek, J.P. (author), van Halem, D. (author)

The removal of bromate (BrO₃ ^-) as a byproduct of ozonation in subsequent managed aquifer recharge (MAR) systems has so far gained little attention. This preliminary study with anoxic batch experiments was executed to explore the feasibility of chemical BrO₃ ^- reduction in Fe-reducing zones of MAR...

A Robust Longitudinal Control Strategy of Platoons under Model Uncertainties and Time Delays

Chen, N. (author), Wang, M. (author), Alkim, Tom (author), van Arem, B. (author)

Automated vehicles are designed to free drivers from driving tasks and are expected to improve traffic safety and efficiency when connected via vehicle-to-vehicle communication, that is, connected automated vehicles (CAVs). The time delays and model uncertainties in vehicle control systems pose challenges for automated driving in real world....

Self-avoiding pruning random walk on signed network

Wang, H. (author), Qu, C. (author), Jiao, Chongze (author), Ruszel, W.M. (author)

A signed network represents how a set of nodes are connected by two logically contradictory types of links: positive and negative links. In a signed products network, two products can be complementary (purchased together) or substitutable (purchased instead of each other). Such contradictory types of links may play dramatically different roles...

Information diffusion backbones in temporal networks

Zhan, X. (author), Hanjalic, A. (author), Wang, H. (author)

Progress has been made in understanding how temporal network features affect the percentage of nodes reached by an information diffusion process. In this work, we explore further: which node pairs are likely to contribute to the actual diffusion of information, i.e., appear in a diffusion trajectory? How is this likelihood related to the...

Design of 3D Wireless Power Transfer System Based on 3D Printed Electronics

Hou, T. (author), Xu, J. (author), Elkhuizen, W.S. (author), Wang, C.C. (author), Jiang, Jiehui (author), Geraedts, Jo M.P. (author), Song, Y. (author)

2D coil design limits the use of wireless power transfer (WPT) in many products with freeform outer shapes. In this paper, enabled by 3D printed electronics, we propose a systematic approach to design and fabricate 3D coils for WPT. Based on the circular spiral and rectangular spiral patterns, 3D receiver and transmitter coils can be...

A Local Particle Filter Using Gamma Test Theory for High-Dimensional State Spaces

Wang, Z. (author), Hut, R.W. (author), van de Giesen, N.C. (author)

Particle filters are non-Gaussian filters, which means that the assumption that the error distribution of the ensemble should be Gaussian is unnecessary. Like the ensemble Kalman filter, particle filters are based on the Monte Carlo approximation to represent the distribution of model states. It requires a substantial number of particles to...

Zhan, X. (author), Li, Z. (author), Masuda, Naoki (author), Holme, Petter (author), Wang, H. (author)

Link prediction can be used to extract missing information, identify spurious interactions as well as forecast network evolution. Network embedding is a methodology to assign coordinates to nodes in a low-dimensional vector space. By embedding nodes into vectors, the link prediction problem can be converted into a similarity comparison task....

Empirics and models of fragmented lane changes

Mullakkal-Babu, F.A. (author), Wang, M. (author), van Arem, B. (author), Happee, R. (author)

Existing microscopic traffic models represent the lane-changing maneuver as a continuous and uninterrupted lateral movement of the vehicle from its original to the target lane. We term this representation as Continuous Lane-Changing (CLC). Recent empirical studies find that not all lane-changing maneuvers are continuous; the lane-changer may...
