‎Bucket recursive trees are an interesting and natural‎ ‎generalization of ordinary recursive trees and have a connection‎ to mathematical chemistry‎. ‎In this paper‎, ‎we give the lower and upper bounds for the moment generating‎ ‎function and moments of the multiplicative Zagreb indices in a‎ ‎randomly chosen bucket recursive tree of size $n$ with maximal bucket size $bgeq1$‎. Also, ‎we consi...

The recovering of a positive density, of which a nite number of moments is assigned, is considered (in the Stieltjes and Hamburger moment problems). In the choice of the approximant the Maximum Entropy approach is adopted. Two main problems are taken into account. 1. A review of diierent criteria concerning the determinacy and indeterminacy of the innnite moment problem is presented. This revie...

background and objectives: constant monitoring of healthcare organizations’ performance is an integral part of informed health policy-making. several hospital performance assessment methods have been proposed in the literature. pabon lasso model offers a fast and convenient method for comparative evaluation of hospital performance. this study aimed to evaluate the relative performance of hospit...

A biocompatible microemulsion system comprising of isopropyl myristate (IPM) as oil, tween 80 as a non-ionic surfactant and isobuthanol as co-surfactant was studied experimentally at 298.15 K. The pseudo-ternary phase diagram for the microemulsion system has been delineated at different surfactant to co-surfactant mass ratio of 1:1, 2.4:1 and 4:1. Some physico-chemical properties such as densit...

Moments and functions of moments are powerful general tools in a vast number of fields, and particularly in the field of image signal processing. In this paper, we present a method for obtaining a set of orthogonal, noise-robust, transformation invariant and distribution sensitive moments, which we call Eigenmoments (EM). EM are obtained by performing eigen analysis in the moment space generate...

with the arguments xj being, in general, rational functions (typically, simple ratios) of kinematic invariants of the original Feynman diagram, and the parameters {γj} and {σk} being linear combinations of the exponents of propagators and the dimension of space-time. The γj and σk are called upper and lower parameters, respectively. These statements follow from the multiple Mellin-Barnes repres...

The model-independent method based on the triangle ideology is implemented to extract the CKM-matrix angle γ in the decays of doubly heavy baryons containing the charmed and beauty quarks. We analyze a color structure of diagrams and conditions to reconstruct two reference-triangles by tagging the flavor and CP eigenstates of D 0 ↔ ¯ D 0 mesons in the fixed exclusive channels. The characteristi...

Determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. In this paper, the maximum power of the MGT-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. In a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...
