The Two Forms of Fractional Relaxation of Distributed Order

The first-order differential equation of exponential relaxation can be generalized by using either the fractional derivative in the Riemann–Liouville (R-L) sense and in the Caputo (C) sense, both of a single order less than 1. The two forms turn out to be equivalent. When, however, we use fractional derivatives of distributed order (between zero and 1), the equivalence is lost, in particular on...

Dielectric Relaxation in Cellulose and its Derivatives

The relaxation processes in cellulose, methyl cellulose, hydroxypropyl cellulose, and hydroxypropylmethyl cellulose were studied by dielectric spectroscopy. The dielectric spectra for these polysaccharides were measured in the frequency range from 100 Hz to 1 MHz and in the temperature range from 100 to 450 K. The dielectric relaxation data for cellulose, methyl cellulose, hydroxypropylmethyl c...

Second-order Derivatives and Rearrangements

Inequality (1.2) is classical and very well known. It has been the object of extensions and variants which can be found in a number of papers and monographs, including [AFLT], [Bae], [BBMP], [BH], [Bro], [BZ], [CP], [E], [H], [Ka2], [Kl], [Ma], [Sp1], [Sp2], [Spi], [Ta1], [Ta5], and [Ta6]. Even if not as popular as (1.2), inequality (1.1) has also been known for a long time, and versions of it ...

Derivatives of Infinite Order

It then follows first that g(x) is continuous, then that g(x) is differentiable in (a, b), finally that g'(#) «=g(#) and so g(x) *ae. If/(#) approaches a limit only for one value of x, however, it does not necessarily do so for other values of x. On the other hand, G. Vitali [lO] and V. Ganapathy Iyer [ó] showed that if fix) is analytic in (a, b) and f(x) approaches a limit for one #o£(0, *), t...

Spin Relaxation in Nematogensand their Deuterated Derivatives

A brief review of spin relaxation (1) in nematogens is given. The usual problems in this area arise from the lack of a good theoretical model and a spin system in which meaningful measurements and direct comparison with the model can be made. The proton and deuteron spin-lattice relaxation in nematics have been extensively studied both theoretically (2,3) and experimentally (4-8). It is general...
