A New and Efficient Meshless Computational Approach for Transient Heat Conduction in Anisotropic Nonhomogeneous Media: Fragile Points Method and Local Variational Iteration Scheme

Abstract A new and efficient computational approach is presented for analyzing transient heat conduction problems. The Fragile Points Method (FPM) utilized for spatial discretization can, on one hand, like many other meshless methods, be free of the requirement of high-quality meshing, and on the other hand, bypass the difficulty of domain integration problem which is commonly seen in Galerkin meshfree methods. With local, polynomial and discontinuous trial and test functions, the...

INFLUENCE OF ORGANISATIONAL FACTORS ON THE IMPLEMENTATION OF PHYSICAL EDUCATION IN EUROPEAN TERTIARY INSTITUTIONS

The purpose of higher education is to produce active and intellectually well-rounded individuals yet, the transition to higher education seems to have deleterious effects on university and college students’ (UCS) fitness levels and physical activity (PA). The aim of this quantitative research was to analyse the influences of organisational factors on the implementation of physical education (PE) among UCS in European tertiary institutions. A purposive sampling method was employed. Seven academic...

Change of antlers morpho-metric parameters and total trophy score in roe deer (Capreolus capreolus L.) in relation to age

The aim of this study was to determine the change in the value of morpho-metric parameters of antlers and the total trophy score in relation to the age of roe deer (Capreolus capreolus L.). The study was conducted on 228 roe deer trophies from the "Barajevska reka" hunting ground in Serbia, aged one to seven years. From the second to the fourth year, the growth of antlers was the most intense, and the differences compared to one year old animals were significant (P <0.001)....

A review of reproduction biology and spawning/ nursery grounds of the most important Adriatic commercial fish species in the last two decades

Recently, despite long-term systematic research of the Adriatic Sea ecosystem, the necessity to improve the existing protection of commercially exploited species occurred since the status of many renewable marine stocks were not in good state. In order to realize that review of scientific knowledge gather within the last two decades was required. In this paper emphasis has been placed on all the scientific knowledge concerning the reproductive biology, spawning and nursery grounds of four ecologically...

Estimating DOA and PPS parameters of signal received by ULA in heavy noise environment

Abstract Estimation of the direction-of-arrival (DOA) and parameters of polynomial phase signal (PPS) impinging on the uniform linear array (ULA) of sensors in heavy-tailed noise environments is considered in this paper. To estimate signal parameters, a recently proposed quasi maximum-likelihood (QML) estimator is adopted. The proposed algorithm consists of two successive steps: (1) noise influence mitigation by using the proposed normalization strategy and (2) signal parameters estimation...

On the Generalization of Merkin’s Theorem for Circulatory Systems: A Rank Criterion

Abstract This paper provides a generalization of the celebrated Merkin theorem. It provides new results on the destabilizing effect of circulatory forces on stable potential systems. Previous results are described and discussed, and the paper uncovers a deeper understanding of the fundamental reason for the destabilization. Instability results in terms of rank conditions that deal with the potential and circulatory matrices that describe the system are obtained, thereby generalizing...
