MATEC Web of Conferences, 2017 Error Correcting Codes are playing a very important role in Video Watermarking technology. Because of very high compression rate (about 1:200) normally the watermarks can barely survive such massive attacks, despite very sophisticated embedding ...

Hadamard-transform fluorescence-lifetime imaging
Optics Express, 2016 We discuss a Hadamard-transform-based fluorescence-lifetime-imaging (HT-FLI) technique for fluorescence-lifetime-imaging microscopy (FLIM). The HT-FLI uses a Fourier-transform phase-modulation fluorometer (FT-PMF) for fluorescence-lifetime measurements, where the modulation frequency of the excitation light is swept linearly in frequency from zero to a

Computer-Aided Civil and Infrastructure Engineering, EarlyView.Abstract Rapid and accurate estimation of seismic responses in city‐scale buildings is critical for post‐earthquake loss assessment and pre‐event identification of vulnerable buildings. However, conventional numerical simulation methods struggle to balance efficiency and accuracy when applied to large‐scale buildings, while existing data‐driven methods

Computationally Efficient Robust Color Image Watermarking Using Fast Walsh Hadamard Transform
Journal of Imaging, 2017 Watermark is the copy deterrence mechanism used in the multimedia signal that is to be protected from hacking and piracy such a way that it can later be extracted from the watermarked signal by the decoder.

Adaptive visible image watermarking based on Hadamard transform
IOP Conference Series: Materials Science and Engineering, 2018 One of the ways for implicit protection of rightful copyright information deals with application of visible watermark embedded in the host image. In this paper, we study behaviour of the proposed function, which makes the embedding of visible watermark ...

Redox behavior of tin in aluminosilicate melts: Implications for the fining process
International Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.Abstract Aluminosilicate glasses are widely used in everyday applications and can be seen as building blocks of modern technology, from display screens to glass‐ceramics. However, due to their high viscosities, gas bubbles can only be removed from aluminosilicate melts at high temperatures, leading to significant energy costs.

Hybrid Precoding-Beamforming Design With Hadamard RF Codebook for mmWave Large-Scale MIMO Systems
IEEE Access, 2017 This paper proposes a hybrid structure for multi-stream large-scale multi-input multi-output (MIMO) beamforming systems, in single-user scenario, using a Hadamard radio frequency (RF) codebook with low-bit resolution phase shifters. We show that Hadamard
