Fractional Programming with Homogeneous Functions
Operations Research, 1974This paper extends the well known results for linear fractional programming to the class of programming problems involving the ratio of nonlinear functionals subject to nonlinear constraints, where the constraints are homogeneous of degree one and the functionals are homogeneous of degree one to within a constant. Two rather general auxiliary problems

Thyroglobulin in Fractions of Thyroid Homogenate
Endocrinology, 1970It is known that, from a homogenate of thyroid gland, lysosomes, colloid droplets and their combined form, “phagosomes,” can be sedimented at 15,000 g. We injected mice with radioiodine and then studied the effect of an injection of thyrotropin on some aspects of the distribution of radioactivity in the 15,000 g pellet obtained from their pooled ...

Bilinear Fractional Integral Along Homogeneous Curves
Journal of Fourier Analysis and Applications, 2016We define the bilinear fractional integral \(T_{\beta}\) along homogeneous curves \(\gamma(t)=(t^{\beta_1}, t^{\beta_2})\) by \[ T_{\beta}(f, g)(x) = \int_{0}^{\infty} f(x-t^{\beta_1}) g(x-t^{\beta_2}) \, t^{\beta-1} \, dt, \] where \(\beta_2 > \beta_1 > \beta > 1\).

Centrifugal fractionation of homogenized milks
Journal of Dairy Research, 1985SUMMARYA set of 12 fractions was isolated from homogenized cows' milk by a method of successive centrifugation steps. The fractions were analysed in terms of fat and protein contents and the diameters of the particles in them were also measured.

Duality in Homogeneous Fractional Programming
Journal of Information and Optimization Sciences, 1980The usual theory of duality for linear fractional programs is extended by replacing the linear functions in the numerator and denominator by arbitrary positively homogeneous convex functions. In the constraints the positive orthant Rn> is replaced by an arbitrary cone A number of closely related pairs of problems are considered and converse as well as ...

The Lane - Emden Fractional Homogenous Differential Equation
Journal of Applied Nonlinear Dynamics, 2017Summary: In this paper we introduce a nonlinear fractional differential equation of Lane-Emden type. We establish a solution which satisfies the Müntz-Szász theorem conditions in terms of power series. Particular solutions are established for different values of the parameters.

Statistical Multiplexing of Homogeneous Fractional Brownian Streams
Queueing Systems, 2004Fractional Brownian motion has been introduced as a mathematically tractable Gaussian traffic model with parameter \( 0.5< H < 1 \) [\textit{I. Norros}, Queueing Syst. 16, 387--396 (1994; Zbl 0811.68059)]. In this paper, the supremum functional of a fractional Brownian motion with a negative linear drift is used to model the queue length of a single ...

Capillary electrophoresis of homogeneous pectin fractions
Carbohydrate Polymers, 2005Capillary electrophoresis (CE) has been used to characterize pectin fractions obtained from mother samples of varying degrees (and intramolecular patterns) of methylesterification (DM). These samples have been carefully produced by fractionation, (a) from the original mother samples on the grounds of molar mass, and (b) subsequently from the daughter ...

A Linear Fractional Program with Homogeneous Constraints by
OPSEARCH, 1999This paper proposes an algorithm for solving a linear fractional functionals program when some of its constraints are homogeneous. Using these homogeneous constraints a transformation matrix T is constructed. Matrix T transforms the given problem into another linear fractional functional program but with fewer constraints.

FRACTIONATION OF OLFACTORY TISSUE HOMOGENATES. ISOLATION OF A CONCENTRATED PLASMA MEMBRANE FRACTION
Journal of Neurochemistry, 1969Abstract— Differential and sucrose‐density‐gradient centrifugation techniques were used for studies on the separation of subcellular particles from rabbit brain and olfactory tissue. Comparisons were made among various fractions from the two types of tissue.
