On model of transport of a medicinal product in an organism

E.L. Pankratov — 2023-06-15

In this paper we introduce a model of transport of a medicinal product in a organism. The model based on
estimation of spatio-temporal distribution of concentration of product. We introduce an analytical
approach for analysis of the considered transport with account of changing of conditions. We consider a
possibility to accelerate and decelerate of transport of the above medicinal product.

Application of new Decomposition Method (AKDM) for the solution of SIR model and Lotka-voltra (Prey-Predator) model

Mulugeta Andualem — 2023-06-15

Solving nonlinear problems analytically are somewhat difficult because of their variety of natures.
Therefore, researchers are always searching for new techniques (analytic, approximate or numerical) to
solve such nonlinear initial value, boundary value, or mixed problems. Based on such a motivation, in
this work, we have developed a new method known as Andualem and Khan Decomposition Method
(AKDM) for the solution of (SIR) model and Lotka-voltra model. We also used mat lab to analysis the
series solution of both models graphically.

Some Results Regarding To New Triple Laplace Transform

Yousef Jafarzadeh — 2023-06-15

In this paper, the new triple Laplace transform is defined. The main results and theorems on the new
triple Laplace transform are investigated. The theory of fractional differential equations based on new
triple Laplace transform is developed in this work.

Analysis and simulation of Accuracy and Stability for Closed Loop Control Systems

Musa Adam Abdullah — 2023-06-15

The design and assessment of closed loop control systems must include accurate and stable accuracy
analysis and simulation. An overview of the significance of closed loop control systems and its uses in
several engineering disciplines is given in this paper. The paper then explores the different techniques
used for evaluating the accuracy and stability of closed loop control systems, including steady-state error
analysis, stability analysis, and simulation techniques. It also discusses the design and tuning of control
algorithms to optimize the performance of the system, and identifies the different factors that can affect
the accuracy and stability of closed loop control systems, such as sensor noise, model inaccuracies, and
environmental disturbances.

On the Covering Radius of DNA Code Over N

P. Chella Pandian — 2023-06-15

In this paper, lower bound and upper bound on the covering radius of DNA codes over N with respect to lee distance are given. Also determine the covering radius of various Repetition DNA codes, Simplex DNA code Type α and Simplex DNA code Type β and bounds on the covering radius for MacDonald DNA codes of both types over N.
