The paper investigates chirp pulse compression as a signal dimension reduction technique in non-coherent Impulse-Radio Ultra-Wideband (IR–UWB) communications. Two common types of non-coherent IR–UWB detection are considered, energy detection of IR–UWB Pulse Position Modulated (PPM) symbols and sample-wise differential detection of Differential Phase Shift Keying (DPSK) IR–UWB symbols, as well a...

Cyclic voltammogram and differential pulse polarograph of octaethyl porphyrin iron(III) chloride in dichloromethane was investigated in the presence of pyridine, imidazole and collidine. Values of E1/2 for FeIII/FeII redox reaction were monitored as a function of axial group concentration, and on the basis of these data, an overall oxidation-reduction and ligand addition scheme was formulated. ...

In this paper, we introduce hybrid of block-pulse functions and Bernstein polynomials and derive operational matrices of integration, dual, differentiation, product and delay of these hybrid functions by a general procedure that can be used for other polynomials or orthogonal functions. Then, we utilize them to solve delay differential equations and time-delay system. The method is based upon e...

In this study, simple, fast and reliable cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV) methods were developed and validated for determination of bosentan in pharmaceutical preparations. The proposed methods were based on electrochemical oxidation of bosentan at platinum electrode in acetonitrile solution containin...

We classify integrable scalar polynomial partial differential equations of second order generalizing the short pulse equation.
