Design, development, calibration, and testing of indigenously developed strain gauge based dynamometer for cutting force measurement in the milling process

Journal of Mechanical Engineering and Sciences, 2020
In this work, a milling dynamometer based on strain gauge with an octagonal and square ring was designed and tested. Strain gauges were attached with the mechanical rings to detect the deformation, during the machining process. Wheatstone bridge circuit

Novel physical network algorithm for indirect measurement of polished rod load of beam-pumping unit

The Journal of Engineering, 2019
A novel neural network algorithm for indirect measurement of the polished rod load of the beam-pumping unit is proposed. The dynamometer card is a two-dimension graph of polished rod load versus horse head position, and it is widely used for working ...

DiaActive protocol: A randomized controlled trial of cognitive‐motor multicomponent exercise to reduce fall rate in older adults with diabetes

Diabetic Medicine, EarlyView.
Abstract Introduction Older adults with diabetes have an increased risk of falls due to neuropathy, impaired bone health and cardiovascular disease, resulting in significant morbidity and mortality. Conventional fall‐prevention programmes primarily target strength and balance, while cognitive‐motor integration, essential for safe mobility in complex ...

NSAID ingestion augments training‐induced muscle hypertrophy and differentially affects muscle mRNA expression, but not strength gains, in trained men

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the impact of NSAID ingestion on resistance exercise training‐induced changes in muscle morphology, function and gene networks relative to placebo ingestion in trained males. Abstract Non‐steroidal anti‐inflammatory drugs (NSAIDs) are widely overused in sports.

An Energy Saving System for a Beam Pumping Unit

Sensors, 2016
Beam pumping units are widely used in the oil production industry, but the energy efficiency of this artificial lift machinery is generally low, especially for the low-production well and high-production well in the later stage.

Acute Effects of Varying Neuromuscular Electrical Stimulation Amplitude on Quadriceps Isometric Torque and Muscle Thickness in Healthy Young Adults: A Randomized Split‐Limb Trial

Physiotherapy Research International, Volume 31, Issue 4, October 2026.
ABSTRACT Introduction Despite the relevance of neuromuscular electrical stimulation (NMES) dosimetry, it is unclear whether increasing the self‐reported tolerated amplitude enhances acute neuromuscular responses. Objective To investigate the acute effects of varying NMES amplitude and type of induced contraction on quadriceps isometric torque (IT) and ...
