Apodization sensor performance for TOPAS fiber Bragg grating
Optical sensors have more capabilities than electronic sensors, and therefore
provide extraordinary developments, including high sensitivity, non-
susceptibility to electromagnetic wave disturbances, small size, and
multiplexing. Furthermore,…

A novel deep learning architecture for drug named entity recognition
Drug named entity recognition (DNER) becomes the prerequisite of other
medical relation extraction systems. Existing approaches to automatically
recognize drug names includes rule-based, machine learning (ML) and deep
learning (DL) techniques.…

Web-based software application design for solar PV system sizing
The solar photovoltaic (PV) energy source systems generally rely on the
availability of sunlight, its duration, and the capacity of storage devices if it
is not a grid-tie system. The components of the PV sources come in different
sizes and…
