Elastic wave and vibration bandgaps in planar square metamaterial-based lattice structures
, 2020In this work, a new type of planar square lattice structures for the attenuation of elastic wave propagation is proposed and designed. To obtain a high vibration attenuation in low frequency ranges, the internal resonance mechanism of the acoustic ...

Square-wave voltammetry (SWV) is one of the four major voltammetric techniques provided by modern computer-controlled electroanalytical instruments, such as Autolab and µAutolab (both EcoChemie, Utrecht), BAS 100 A (Bioanalytical Systems) and PAR Model 384 B (Princeton Applied Research).

Square-wave voltammetry is a technique that is readily available to anybody applying modern electrochemical measuring systems. Its use can be beneficial in analytical applications as well as in fundamental studies of electrode mechanisms. On a first glance it seems that the analytical application of square-wave voltammetry is rather simple and does not

Over the past few years, several research programs have been conducted to determine the effect of welding current waveform characteristics on weld qualities.[1]-[3] It was recorded that gradual weld quality improvement was achieved as the output-current waveshape more nearly approached that of a symmetrical square wave.

AbstractTheoretical and practical aspects of square wave conductometry are discussed. Equilibrium conditions for a simple bridge circuit are compared with those for classical sine wave conductometry. It is shown that square wave conductometry is less dependent on the choice of the cell parameters.As an example, square wave conductometry is applied to ...

A patient with presenile dementia had instability of ocular fixation caused by small rapid horizontal eye movements (square-wave jerks). High resolution recordings of these eye movements were characteristic of microsaccades, which ordinarily occur during fixation, in all respects except amplitude.

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1982
Abstract A new electroanalytical technique involving the use of two indicator electrodes polarised by a square-wave potential is described. The output signal is a de faradaic current proportional to the concentration of the electroactive species. The technique is very sensitive, shows rapid response to concentration change and the observed current is

Thin-layer square wave voltammetry and square wave stripping voltammetry
Analytical Chemistry, 1987The feasibility of combining the highly sensitive techniques of square wave voltametry (SWV) and square wave stripping voltametry (SWSV) with a commercially available thin-layer electrochemical cell having a single-working electrode is demonstrated.

There are many electronic circuits and/or devices that require nonsinusoidal voltage or current waveforms in their operation. Some examples of these are the horizontal and vertical sweep circuits in television receivers as well as digital circuits including watches, calculators, and computers.
