Li, Y. (author), Song, Y. (author), Horvath, I. (author), Opiyo, E.Z. (author), Zhang, G. (author)In the designing and modeling of CPSs, the information acquisition and processing processes are often application dependent and process oriented. Those information management frameworks are simple and effective for small scale systems. However, many functions developed are not reusable or cannot be directly re-used, when a large number of...conference paper 2014

Zhang, H. (author), Wahls, S. (author), Brühl, M. (author)In the past decade, observations in the German estuaries such as the rivers Elbe and Weser show increasingly serious damage to bank protection structures (groins and revetments). This damage is caused mainly by waves induced by the passing of big container ships in the shallow and narrow maritime waterways. These ship-induced 3D wave fields...conference paper 2021

Chang, Z. (author), Zhang, H. (author), Schlangen, E. (author), Šavija, B. (author)The aim of this work is to investigate the fracture process of concrete under various boundary conditions. Although numerous concrete fracture tests have been reported, showing the failure behavior of concrete, their evaluation is ambiguous due to the limitations of specimen size and experimental conditions. Therefore, it is necessary to use...conference paper 2019

Slob, E.C. (author), Zhang, L. (author)Elimination of multiples from acoustic reflection data is important to reduce the effect of their presence in velocity model building and subsequent imaging. Many processing schemes assume only primary reflection events are present in the data. Free-surface multiple elimination is an established technology, but internal multiple elimination is...conference paper 2019

Zhang, Kaiwen (author), Coutino, Mario (author), Isufi, E. (author)Graph sampling strategies require the signal to be relatively sparse in an alternative domain, e.g. bandlimitedness for reconstructing the signal. When such a condition is violated or its approximation demands a large bandwidth, the reconstruction often comes with unsatisfactory results even with large samples. In this paper, we propose an...conference paper 2021

Middelburg, L.M. (author), el Mansouri, B. (author), van Zeijl, H.W. (author), Zhang, Kouchi (author), Poelma, René H. (author)In this work a method is described to investigate process variations across a wafer. Through wafer MEMS spiral resonators were designed, simulated, fabricated and characterized by measuring the eigenfrequency and corresponding mode shapes. Measuring the eigenfrequency and resulting spectral behavior of resonators on different locations on the...conference paper 2017

Zhang, Zheming (author), Wang, Fang (author), Pang, Y. (author), Yan, Gaowei (author)The problem of misalignment of the original measurement model is caused by nonlinear, time-varying characteristic of the batch process. In this paper, a method based on geodesic flow kernel (GFK) for feature transfer is proposed. By mapping data into the manifold space, the feature transfer from source domain to target domain is implemented....conference paper 2020

Sattari, R. (author), van Zeijl, H.W. (author), Zhang, Kouchi (author)This study presents a novel manufacturing process and design towards an enhanced sensitivity of an in-package relative humidity sensor. The device comprises multi-width interdigital electrodes which make oxide pillars appear during wet chemical etching in the fabrication process. Those oxide pillars appear only in wider areas while completely...conference paper 2023

Inamdar, A.S. (author), Hauck, Torsten (author), van Soestbergen, Michiel (author), van Driel, W.D. (author), Zhang, Kouchi (author)Model order reduction techniques are developed and utilized to make numerical simulations more efficient. The use of Reduce Order Models (ROM) also enables data exchange with external parties without disclosing the sensitive information present in a Full-Order Model (FOM). It is crucial to optimize for both the efficiency and accuracy of a ROM...conference paper 2024

Zhang, J. (author)Recently, flexible, wearable and disposable electronics have attracted a lot of attention. Printing enables low-cost fabrication of circuits on flexible substrates. Printed organic and metal oxide thin-film transistors (TFTs) have been researched intensively due to the ease of solution-processing. But their carrier mobility and reliability are...doctoral thesis 2015

Zhang, B. (author)In the financial world, two tasks are of prime importance: model calibration and portfolio hedging. For both tasks, efficient option pricing is necessary, particularly for the calibration where many options with different strike prices and different maturities need to be priced at the same time. Therefore, a fast yet accurate pricing method is a...doctoral thesis 2012
