Landmarking Technique for Improving YOLOv4 Fish Recognition in Various Background Conditions

Advances in Science, Technology and Engineering Systems Journal, Volume 8, Issue 3, Page # 100–107, 2023; DOI: 10.25046/aj080312
Abstract:

The detection and classification of fish is a prevalent and fascinating area of study. Numerous researchers develop skills in fish recognition in both aquatic and non-aquatic environments, which is beneficial for population control and the aquaculture industry, respectively. Rarely is research conducted to optimize the recognition of fish with diverse backgrounds. This paper proposes a…

Active Simulation of Grounded Parallel-Type Immittance Functions Employing VDBAs and All Grounded Passive Components

Advances in Science, Technology and Engineering Systems Journal, Volume 8, Issue 1, Page # 131–137, 2023; DOI: 10.25046/aj080116
Abstract:

This communication proposes a grounded immittance function simulator that, depending on the proper choice of the passive components, can simulate parallel-type impedances of the R-L, R-C, and L-C forms. Only two grounded passive components and two voltage differencing buffered amplifiers (VDBAs) are used to implement the suggested circuit. All three simulated equivalent elements, namely Req,…

Electronically Tunable Triple-Input Single-Output Voltage-Mode Biquadratic Filter Implemented with Single Integrated Circuit Package

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 1, Page # 1120–1127, 2021; DOI: 10.25046/aj0601125
Abstract:

This article proposes a compact and simple design of electronically adjustable voltage-mode biquadratic filter using fundamental active cell implemented on a single integrated circuit (IC) package as LT1228. The proposed circuit having triple inputs and single output (TISO) employs namely one resistor and two capacitors as the passive components. All the five possible biquadratic filtering…
