M-wave changes caused by brief voluntary and stimulated isometric contractions
Introduction Under isometric conditions, the increase in muscle force is accompanied by a reduction in the fbers’ length. The efects of muscle shortening on the compound muscle action potential (M wave) have so far been ... -
Magnetic binary encoding system based on 3D printing and GMI detection prototype
In this work, the feasibility of a magnetic binary encoding system using 3D printing technology is analyzed. The study has a double interest, that is, the possibility of printing a 3D piece that contains the codified ... -
Mapping the conductivity of graphene with electrical resistance tomography
Electronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene ... -
Masked least-squares averaging in processing of scanning-EMG recordings with multiple-discharges
Removing artifacts from nearby motor units is one of the main objectives when processing scanning-EMG recordings. Methods such as median filtering or masked least-squares smoothing (MLSS) can be used to eliminate artifacts ... -
A masked least-squares smoothing procedure for artifact reduction in scanning-EMG recordings
Scanning-EMG is an electrophysiological technique in which the electrical activity of the motor unit is recorded at multiple points along a corridor crossing the motor unit territory. Correct analysis of the scanning-EMG ... -
Maximum expected ramp rates using cloud speed sensor measurements
Large ramps and ramp rates in photovoltaic (PV) power output are of concern and sometimes even explicitly restricted by grid operators. Battery energy storage systems can smooth the power output and maintain ramp rates ... -
Measurement of paracetamol concentration using an erbium-doped fiber ring cavity
Process Analytical Technology (PAT) has been increasingly used in the pharmaceutical industry to monitor essential parameters in real-time during pharmaceutical processes. The concentration of Active Pharmaceutical Ingredients ... -
