Animal Trajectory Imputation and Uncertainty Quantification via Deep Learning

Environmetrics, Volume 36, Issue 6, September 2025.
ABSTRACT Imputing missing data in animal trajectories is crucial for understanding animal movements during unobserved periods. However, the traditional methods, such as linear interpolation and the continuous‐time correlated random walk model, are often inadequate to capture the complexity of animal movements.

Randomized Orthogonalization Process With Reorthogonalization

Numerical Linear Algebra with Applications, Volume 32, Issue 4, August 2025.
ABSTRACT The dimension reduction technique of random sketching is advantageous in significantly reducing computational complexity. In orthogonalization processes like the Gram‐Schmidt (GS) algorithm, incorporating random sketching results in a halving of computational costs compared to the classical/modified Gram‐Schmidt (CGS/MGS) algorithms, while ...

SECURE TRANSMISSION OF BIO-MEDICAL DATA USING STEGANOGRAPHY

ICTACT Journal on Communication Technology, 2018
To transmit secret data over the internet, the information should be sent in a way attacker finds it difficult to read the secret data. In this paper patient’s secret information is hidden in the bio-medical signal like ECG/EEG/PPG.

Sketched and Truncated Polynomial Krylov Methods: Evaluation of Matrix Functions

Numerical Linear Algebra with Applications, Volume 32, Issue 1, February 2025.
ABSTRACT Among randomized numerical linear algebra strategies, so‐called sketching procedures are emerging as effective reduction means to accelerate the computation of Krylov subspace methods for, for example, the solution of linear systems, eigenvalue computations, and the approximation of matrix functions.

Trotterless Simulation of Open Quantum Systems for NISQ Quantum Devices

Advanced Quantum Technologies, Volume 8, Issue 1, January 2025.
Open quantum systems exhibit complex dynamics that can be simulated on quantum computers to provide physical insights into their behavior. This work proposes a new method for simulating these systems that reduces the effect of noise and errors on modern quantum hardware.

Green communication systems via a wavefront multiplexing technique

Systems Engineering, Volume 28, Issue 1, Page 5-14, January 2025.
Abstract A green communication scheme using an orthogonal wavefront (WF) multiplexing (Muxing) scheme spatially combined with orthogonal frequency‐division multiplexing (OFDM) techniques is proposed. It forms a spatial WF OFDM transceiver. The WF Muxing technique serves as the preprocessing and postprocessing method of the WF OFDM transceiver.
