Seismic data interpolation using an anti-over-fitting mixed-scale dense convolutional neural networkZhang, D. (author), Verschuur, D.J. (author)Seismic data interpolation is a topic well suited for deep learning (DL) applications. Scaling operation-based DL neural networks, e.g., U-Net, have been popular since its booming development in the field of seismic data processing. Although many successful studies using U-Net on seismic data, scientists start to realize the downside of its...conference paper 2023

(author), Mol, Jan Willem (author), Wilmink, Rinse (author)Infragravity (IG) waves are key drivers for coastal erosion and thus need to be properly included in process-based modelling of coastal hazards. Uncertainties remain regarding the offshore boundary conditions for these long waves. Typically, only bound IG waves are included at the boundary, which means that the possible contribution of free IG...conference paper 2023

Ji, X. (author), van Zeijl, H.W. (author), Jiao, Weiping (author), He, S. (author), Du, L. (author), Zhang, Kouchi (author)The trend to 3D and heterogeneous integration enable driving multi-functional blocks in one package. Flip-chip integration is currently playing an important role and is based on solder joints. To overcome the limitations of solder joints, all-copper interconnects have been investigated to meet electrical, thermal, and reliability demands in...conference paper 2023

Zhang, J. (author), Gallo, A.J. (author), Ferrari, Riccardo M.G. (author)Multiplicative watermarking (MWM) is an active diagnosis technique for the detection of highly sophisticated attacks, but is vulnerable to malicious agents that use eaves-dropped data to identify and then remove or replicate the watermark. In this work, we propose a scheme to protect the parameters of MWM, by proposing a design strategy based...conference paper 2023

Ruzzi, Alessandro (author), Shi, X. (author), Wang, Xi (author), Li, Gengyan (author), De Mello, Shalini (author), Chang, Hyung Jin (author), Zhang, X. (author), Hilliges, Otmar (author)We propose GazeNeRF, a 3D-aware method for the task of gaze redirection. Existing gaze redirection methods operate on 2D images and struggle to generate 3D consistent results. Instead, we build on the intuition that the face region and eyeballs are separate 3D structures that move in a coordinated yet independent fashion. Our method leverages...conference paper 2023

Zhang, H. (author), Berkhout, Marco (author), Makinwa, K.A.A. (author), Fan, Q. (author)Class-D amplifiers (CDAs) are widely used in audio applications where a high power efficiency is required. As most audio sources are digital nowadays, implementing digital-input CDAs results in higher levels of integration and lower cost. However, prior open-loop digital-input CDAs suffer from high jitter sensitivity and output-stage...conference paper 2023

Cui, Z. (author), Fan, X. (author), Zhang, Kouchi (author)In this paper, we apply the Eshelby's solution to study the effect of passivation layer on electromigration (EM) failure in a conductor. The passivation layer is considered as an elastic material, not a rigid layer anymore. Thus, the deformation and stress evolution in the conductor during EM are related to the mechanical property of the...conference paper 2023
