Spectral fractorization in discrete systems

1970 IEEE Symposium on Adaptive Processes (9th) Decision and Control, 1970
The spectral factorization in discrete systems is studied in this paper. Three theorems describing the solution and its characteristics are presented. A computer program incorporating this technique is applied to the orbit determination problem using the ranging system.

Material performance measurement of a promising circuit element: fractor-part I: driving-point impedance function of the arbitrary-order fractor in its natural implementation

Materials Research Innovations, 2015
AbstractHere and in the companion paper, the physical performance measurement, especially measurement units and physical dimensions of fractance and rules for fractors in series and parallel are discussed. The concept of fractance, as the fractional-order impedance of a fractor, arose following the successful synthesis of a fractional differentiator in

Material performance measurement of a promising circuit element: fractor-part II: measurement units and physical dimensions of fractance and rules for fractors in series and parallel

Materials Research Innovations, 2015
AbstractUp to now, no effective physical performance measurements have been proposed for fractor, a promising circuit element, especially with regard to the measurement units and physical dimensions of fractance. Motivated by this need, in this paper, I study the physical performance measurement of fractor.

Dynamic structure fractor of a polymer in dilute solution

2008
The dynamic structure factor S (k, ω) for an infinitely long single polymer chain is calculated from the Vlasov equation. The procedure is analogous to that of Nelkin and Ranganathan for a classical fluid. The polymer density is, however, non-uniform; the monomer density is assumed to be Gaussian about the center of mass.

Friction fractor and holdup studies for lubricated pipelining—II Laminar and models of eccentric core flow

International Journal of Multiphase Flow, 1994
Abstract A model of core-annular flow in which the oil core is a perfect cylinder with generators parallel to the pipe wall, but off-center, is studied in laminar and turbulent flow to assess the effects of eccentricity and the volume flow rate ratio on the friction factor and holdup ratio.

Spectral factorization of Laurent polynomials

Advances in Computational Mathematics, 1997
The authors analyze the results of numerical experiments for factoring a Laurent polynomial \(a(z)= \sum^m_{j=-m} a_jz^j\), \(a_j=\overline a_j= a_{-j}\), \(a(z)\geq 0\), \(|z|=1\). Five numerical methods are tested: the Bauer method, the Wilson method, the roots method, the minimum phase method and the Cepstral method.

Abstract P142: Regulation of Brain Derived Neurotrophic Fractor (BDNF) Expression by Angiotensin II in the Adrenals and the Brain

Hypertension, 2015
Circulating Ang II activates central angiotensinergic pathways, and an amplifying aldosterone (aldo)-MR-ENaC-AT 1 R neuromodulatory pathway which are critical for several forms of hypertension. We hypothesized that in addition Ang II increases BDNF expression in both the CNS and adrenal which plays a balancing role ...

Factors Affecting the Rate of Gluconeogenesis from L-Cysteine in the Perfused Rat Liver

The Journal of Nutrition, 1976
It has been shown that the net rate of gluconeogenesis from cysteine was only 10% the rate observed from pyruvate. This suggested that the rate limiting step in gluconeogenesis from cysteine was between cysteine and pyruvate. Evidence is presented showing that the cysteine-sulfinate pathway does not play a regulating role in the conversion of cysteine ...
