EDGE-NEIGHBOR RUPTURE DEGREE ON GRAPH OPERATIONSmathsjournal
Vulnerability and reliability parameters measure the resistance of the network to disruption of operation after the failure of certain stations or communication links in a communication network. An edge subversion strategy of a graph , say , is a set of edge(s) in whose adjacent vertices which is incident with the removal edge(s) are removed from . The survival subgraph is denoted by . In this paper we give some results for the edge-neighbor-rupture degree of the graph operations and Thorny graph types are examined.
A New Method For Solving Kinematics Model Of An RA-02IJERA Editor
The kinematics miniature are established for a 4 DOF robotic arm. Denavit-Hartenberg (DH) convention and the
product of exponential formula are used for solving kinematic problem based on screw theory. For acquiring
simple matrix for inverse kinematics a new simple method is derived by solving problems like robot base
movement, actuator restoration. Simulations are done by using MATlab programming for the kinematics
exemplary.
A landing gear assembly consists of various components viz. Lower side stay, Upperside stay, Locking actuators, Extension actuators, Tyres, and Locking pins to name a few. Each unit having a specific operation to deal with, in this project the main unit being studied is the lower brace. The primary objective is to analyse stresses in the element of the lower brace unit using strength of materials or RDM method and Finite Element Method (FEM) and compare both. Using the obtained data a suitable material is proposed for the component. The approach used here is to study the overall behaviour of the element by taking up each aspect, finally summing up the total effect of all the aspects in the functioning of the element.
New Algorithm to calculate kinetic parametersMuratz13
We proposed a new algorithm (GMN) for determining pre-exponential and activation energy
of curing process. This method is based on the combination of tanh fitting for the measured
conversion values via least squares minimization technique and linear fitting for the kinetic parameters. Experimentally determined differential scanning calorimetry (DSC) data sets for an
epoxy resin functionalized by single wall carbon nanotubes are used for the verification of the
proposed method. The results obtained from the proposed algorithm are also compared with the
methods reported in the literature.

Higher-Order Conjugate Gradient Method (HCGM) For Solving Continuous Optimal ...iosrjce
In this paper, we considered the role of penalty when the higher-order conjugate gradient method
(HCGM) was used as a computational scheme for the minimization of penalised cost functions for optimal
control problems described by linear systems and integral quadratic costs. For this family of commonly
encountered problems, we find out that the conventional penalty methods require very large penalty constants
for good constants satisfaction. Numerical results shows that, as the penalty constant tend to infinity, the
convergence rate of the method becomes poor. To circumvent the poor convergence rate of the penalty method,
the HCGM was often considered as a good substitute to accelerate the convergence.

In this paper, the variational iteration method (VIM) is used to get an approximate solution for a
system of two coupled nonlinear ordinary differential equations which represent the concentrations of carbon
dioxide 퐶푂2 and phenyl glycidyl ether. In this system there are boundary conditions of Dirichlet type and the
other is a mixed set of Neumann and Dirichlet type. Our calculations evidenced by tables and figures for the
analysis of the maximal error remainder values. The variational iteration method gives approximate solutions
with fast convergence. Comparison with the results obtained by the Adomian decomposition method (ADM)
reveals that the numerical solutions obtained by the VIM converge faster than those of Adomian's method. The
software we used in our study of these calculations is Mathematica®

A new three-term conjugate gradient method with application to regression an...IJECEIAES
Conjugate gradient (CG) method is well-known for its ability to solve unconstrained optimization (UO.) problems. This article presenting a new CG method with sufficient descent conditions which improves the former method developed by Rvaie, Mustafa, Ismail and Leong (RMIL). The efficacy of the proposed method has been demonstrated through simulations on the Kijang Emas pricing regression problem. The daily data between January 2021 to May 2021 were obtained from Malaysian Ministry of Health and Bank Negara Malaysia. The dependent variable for this study was the Kijang Emas price, and the independent variables were the coronavirus disease (COVID-19) measures (i.e., new cases, R-naught, death cases, new recovered). Data collected were analyzed on its correlation and coefficient determinant, and the influences of COVID-19 on Kijang Emas price was examined through multiple linear regression model. Findings revealed that the suggested technique outperformed the existing CG algorithms in terms of computing efficiency.
Hybrid Simulated Annealing and Nelder-Mead Algorithm for Solving Large-Scale ...IJORCS
This paper presents a new algorithm for solving large scale global optimization problems based on hybridization of simulated annealing and Nelder-Mead algorithm. The new algorithm is called simulated Nelder-Mead algorithm with random variables updating (SNMRVU). SNMRVU starts with an initial solution, which is generated randomly and then the solution is divided into partitions. The neighborhood zone is generated, random number of partitions are selected and variables updating process is starting in order to generate a trail neighbor solutions. This process helps the SNMRVU algorithm to explore the region around a current iterate solution. The Nelder- Mead algorithm is used in the final stage in order to improve the best solution found so far and accelerates the convergence in the final stage. The performance of the SNMRVU algorithm is evaluated using 27 scalable benchmark functions and compared with four algorithms. The results show that the SNMRVU algorithm is promising and produces high quality solutions with low computational costs.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
