Comment on “Enhancement of pyrolysis spray disposal performance using thermal time-response to precursor uniform deposition” by K. Boubaker, A. Chaouachi, M. Amlouk and H. Bouzouita. On the earliest definition of the Boubaker polynomials

Investigation of Nano-keyhole Cooling Evolution Using Boubaker Polynomials Expansion Scheme (BPES)

“…The use of the Colombian approximation 7], Newtonian laws along with the already established Boubaker polynomials expansion scheme BPES [8][9][10][11][12][13][14][15][16][17][18], allowed monitoring temperature dynamical profiles. The yielded profiles could be compared successfully compared to those published by R. Rai et al [25], H. Al-Kazzaz et al [26], P. Solana et al [27], and C. S. Wu et al [28].…”

“…Equation (17), it solved using the Boubaker polynomials expansion scheme BPES [8][9][10][11][12][13][14][15][16][17][18]. As this form of heat loss principle is sometimes not very precise; an accurate formulation may require analysis of heat flow, based on the (transient) heat transfer equation in a nonhomogeneous, or else poorly conductive, medium.…”

Effect of europium content on physical properties of In2O3 thin films for sensitivity and optoelectronic applications

“…The effective absorptivityα, as defined in precedent studies [55][56][57][58], is the mean normalized absorbance weighted by I (λ) AM1.5 , the solar standard irradiance:…”

SnxSy compounds growth by controlled sulfurisation of SnO2

“…where I(˜ ) AM1.5 is the Reference Solar Spectral Irradiance, fitted using the Boubaker Polynomials Expansion Scheme (BPES) [31][32][33][34][35][36][37][38][39]:…”
