DOI: 10.1007/s10015-021-00699-7

Abstract: Facial skin temperature (FST) has also gained prominence as an indicator for detecting anomalies such as fever due to the COVID-19. When FST is used for engineering applications, it is enough to be able to… read more here.

DOI: 10.1007/s11123-018-0531-0

Abstract: We show how a wide range of stochastic frontier models can be estimated relatively easily using variational Bayes. We derive approximate posterior distributions and point estimates for parameters and inefficiency effects for (a) time invariant… read more here.

DOI: 10.1007/s11760-018-1301-1

Abstract: In this work, a frequency-based dimensionality reduction technique using variational mode decomposition (VMD) is proposed. Dimensionality reduction is a very important aspect of preprocessing in case of hyperspectral image (HSI) analysis where this step helps… read more here.

DOI: 10.1007/s40098-020-00475-7

Abstract: In this paper, a rectilinear slope of homogenous rock is analyzed by using the variational method. The strength of the rock medium is assumed to be governed by the Hoek–Brown failure criterion. Although the variational… read more here.

DOI: 10.1088/1361-6404/aaf115

Abstract: The importance of learning symbolic computation in research in theoretical sciences cannot be overemphasised. While Fortran and/or C programming laboratories have become an essential part of MSc curricula now, symbolic computing is almost never taught.… read more here.

DOI: 10.1109/jsac.2022.3191346

Abstract: We investigate the potential of adaptive blind equalizers based on variational inference for carrier recovery in optical communications. These equalizers are based on a low-complexity approximation of maximum likelihood channel estimation. We generalize the concept… read more here.

DOI: 10.1109/tccn.2025.3570452

Abstract: Existing communication hardware is being exerted to its limits to accommodate for the ever increasing Internet usage globally. This leads to non-linear distortion in the communication link that requires non-linear equalization techniques to operate the… read more here.
