Design of a distributed optical fiber sensor system for measuring immersed tunnel joint deformationsZhang, X. (author), Broere, W. (author)Monitoring the deformations of immersed tunnels is important during the entire tunnel service life to assess the structural integrity of the tunnel. Conventional joint deformation monitoring is based on manual levelling measurements and normally occurs only at multi-year intervals, which does not allow to capture short term deformation...journal article 2023

Lesueur, M.J.B.P. (author), Zhang, X. (author), Poulet, Thomas (author), Veveakis, Manolis (author)The seminal work of Gurson (J Eng Mater Technol 99:2–5, 1977) on a simplified pore structure, a single spherical pore, first provided a theoretical relationship between the yield stress and the porosity. This contribution extends the approach to determine the macroscopic yield of a porous material by taking explicitly into account its...conference paper 2023

Zhang, X. (author), Hassan HosseinNia, S. (author)Reset control systems have possessed the potential to meet the demands of machines, such as faster response times, improved disturbance rejection and enhanced tracking performance. However, prior research on the analysis and design of reset controllers has been restricted to the assumption of two resets per period, neglecting multiple-reset...conference paper 2023

Broere, W. (author), Zhang, X. (author)Daily and seasonal deformation behavior of immersed tunnels potentially impacts the structural integrity. In this study, distributed optical fiber sensors (DOFS) are used to instrument both dilation and immersion joints of the Heinenoordtunnel, an immersed tunnel in the Netherlands. This DOFS system proves capable of measuring joint opening and...conference paper 2023

(author)The estuarine turbidity maximum (ETM) in the Yangtze Estuary Delta (YED) is muddy by definition and lacks bottom undulations. However, since 2013, a remarkable change has occurred in the YED. Recent images detected by a multibeam echosounder system, SeaBat 7125, for the first time have confirmed widespread regions of subaqueous dunes in the...journal article 2022

Zhang, X. (author), Kaczmarek, M.B. (author), Hassan HosseinNia, S. (author)In this paper, we introduce a new representation for open-loop reset systems. We show that at steady-state a reset integrator can be modelled as a parallel interconnection of the base-linear system and piece-wise constant nonlinearity. For sinusoidal input signals, this nonlinearity takes a form of a square wave. Subsequently, we show how the...conference paper 2022
