Therefore, in this paper, a new metaheuristic algorithm (BAT algorithm) is used to estimate the Stress strength reliability system for the generalized inverse Pareto distribution. Furthermore, some statistical properties for generalized inverse Pareto distribution are derived. In a
simulation study, the BAT algorithm and the classical Maximum Likelihood (MLE) method are compared using the Relative efficiency criterion. The results show that the BAT variant estimates the parameters more accurately than the MLE.
This study examined the fnbA gene, which plays a role in biofilm formation, in Staphylococcus aureus bacteria that were exposed to copper nanoparticles (CuNPs) produced using an aqueous extract from the leaves of Myrtus communis and Nerium oleander plants.

Show MoreThis study examines the problems with the assessment of river water quality, which is affected by multiple water quality parameters (WQPs) that have inherent uncertainties and uneven decision-maker judgments. To cope with these uncertainties, we use soft sets, fuzzy sets, and fuzzy soft sets. In particular, we first present the square root mean square (SQRTMS) and a water pollution score (WPS) for fuzzy soft sets and propose a novel water pollution assessment framework, i.e., the fuzzy soft multi-criteria group decision-making model (Ω-model). This model produces Ω score, a weighted water pollution score, to classify pollution levels. The proposed methodology is made on water quality indices of Haora River in Tripura India, which ser

The ongoing changes in computer performance are affecting the efficiency of
string searching algorithms. The size of main memory in typical computers
continues to grow, but memory accesses require increasing numbers of instruction
cycles.
One of the most important data structure which is used to improve the string
searching is the Trie tree.
The name Trie comes from the word “retrieval”. This data structure dose not store
the data as specific elements, but rather as a path through the tree.
This research aims to improve the performance of the Trie tree by using a proposed
sample function in trie algorithm which improve space utilization and decrease the
number of the search levels in

the flow of infection disease in a population is proposed and studied. It is
assumed that the disease divided the population into five classes: immature
susceptible individuals (S1) , mature individuals (S2 ) , infectious individual
(I ), removal individuals (R) and vaccine population (V) . The existence,
uniqueness and boundedness of the solution of the model are discussed. The
local and global stability of the model is studied. Finally the global dynamics of
the proposed model is studied numerically.
The work in this paper focuses on solving numerically and analytically a nonlinear social epidemic model that represents an initial value problem of ordinary differential equations. A recent moking habit model from Spain is applied and studied here. The accuracy and convergence of the numerical and approximation results are investigated for various methods; for example, Adomian decomposition, variation iteration, Finite difference and Runge-Kutta. The discussion of the present results has been tabulated and graphed. Finally, the comparison between the analytic and numerical solutions from the period 2006-2009 has been obtained by absolute and difference measure error.
Diabetes mellitus is a form of metabolic disorder where patients are incapable to organize glucose metabolism. The most common types are Type I and Type II, constituting about 10% and 90% of cases, respectively. The cause of type I diabetes, which usually spreads in children and adolescents, is the disability of the endocrine system to produce insulin. On the other hand, The most common type of diabetes, type II diabetes, is often presented in adults. It is usually presented as a collection of insulin deficiency and insulin resistance. This work was done to estimate the count of microbiota in diabetics to find an appraoch for detection and follow-up treatment. The count of two types of bacteria Lactobac

A number of Lnx Oy rare-earth oxides where Ln = La, Ce, Pr, Nd, Sm, Eu, Tb,
Dy and Er, x=1, 2, 4, 6 and y=2, 3, 7, 11 have been studied by powder
diffractometry and pycnometry coupled with the simulation of their lattice
dimensions by empirically derived pair potentials using the GULP code.
Crystallographic analysis showed the oxides exist in the tri, tetra and mixed tri-tetra
valency with Bravias lattices: hexagonal- P, cubic- I and cubic- F as a result of the
oxidation state assumed by the Ln element that may be caused by the nature of the
oxide or preparation process involved. Unit cell volumes of the oxides that exhibit
identical Bravias lattices reflect a behavior that can be correlated with the atomic
