Classifying superconductivity in ThH-ThD superhydrides/superdeuterides

A Telescope Comparison Lemma for Thh

We extend to the non-connective case a lemma of Bökstedt about the equivalence of the telescope with a more complicated homotopy colimit of symmetric spectra used in the construction of THH.

Bearing Faults Classification Using THH and Neural Network

The induction machine has many advantages: its specific power, its strength, relatively low manufacturing cost and minimal maintenance. But despite all these qualities, a number of faults can affect the life of the machine showing premature failures. The purpose of preventive maintenance in real time, we introduce a new signal processing technique based on HilbertHuang Transform (HHT) and margi...

THD Analysis in Closed-Loop Analog PWM Class-D Amplifiers

In this paper, we investigate the parameters affecting Total Harmonic Distortion (THD) and Power Supply Rejection Ratio (PSRR) in PWM Class D Amplifiers (CDAs) on the basis of linear models with feedback. From our mathematical analysis, we show that the THD of a PWM Class D amplifier with feedback can be improved by increasing the gain of the integrator through adding another amplifier at the o...

THD and mucopexy: Efficacy and controversy

AIMS Transanal haemorrhoidal dearterialisation and mucopexy has evolved in recent years as a popular minimally invasive non-excisional surgery for symptomatic prolapsing haemorrhoids. The long-term outcome of this procedure however, remains to be established. We aim to analyse the long-term outcome of THD-mucopexy in the management of prolapsing haemorrhoids based on the evidence of a prospecti...
