MOTIVATION Classification of biological samples by microarrays is a topic of much interest. A number of methods have been proposed and successfully applied to this problem. It has recently been shown that classification by nearest centroids provides an accurate predictor that may outperform much more complicated methods. The 'Prediction Analysis of Microarrays' (PAM) approach is one such exampl...
Article history: Received 30 October 2015 Received in revised form 3 March 2016 Accepted 8 March 2016 Available online 17 March 2016 In many scientific areas, researchers collect multivariate time profile data on the evolution of a set of variables across time for multiple persons. For instance, clinical studies often focus on the effects of an intervention on different symptoms for multiple pe...
In this research, the production of Aluminum matrix composites (AMCS) consolidated by hot powder extrusion along with physical and mechanical properties of extruded bars have been studied. The matrix alloy was prepared from elemental powders of Al and 10wt% Ti. The composites comprises 5,10,15 or 20 vol% SiC or Al2O3 particles with an average size of 5 micron. The powder mixtures were sealed ...
The studied sample presents garnet textural sector-zoning as inclusions in two types in garnet schist from Morlaix, North-West Brittany, France. Crystal size distributions (CSD) of quartz crystals were measured in both types inclusions, in the matrix and strain shadows around garnet porphyroblasts using Back-scatter electron (BSE) images. The CSD plots of quartz crystals show an increase of ave...
An iterative definition of any n variable mean function is given in this article, which iteratively uses the two-variable form of the corresponding two-variable mean function. This extension method omits recursivity which is an important improvement compared with certain recursive formulas given before by Ando-Li-Mathias, PetzTemesi. Furthermore it is conjectured here that this iterative algori...
The main objective of this research investigational studies is to formulate floating matrix tablets glimipride by applying simplex centroid design for optimization technique and direct compression method. Centroid configuration was drilled as an enhancement strategy adjusting the amount three components all while holding back their total concentration constant. Ingredients HPMC K15m, Kappa-carr...
We study the least-squares (LS) functional of the canonical polyadic (CP) tensor decomposition. Our approach is based on the elimination of one factor matrix which results in a reduced functional. The reduced functional is reformulated into a projection framework and into a Rayleigh quotient. An analysis of this functional leads to several conclusions: new sufficient conditions for the existenc...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
in this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (ii) sulfate as metal precursor and polyvinylpyrrolidone k-30 (pvp k-30) as surfactant agent. the reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. characterization o...
