Some types of generalized closed and generalized star closed sets in topological ordered spaces

Volety V. S. Ramachandram*

Abstract

In the present work our intention is to establish relationship between new types of closed sets namely g*b-closed sets (resp.gb-closed) and g*i-closed sets(resp.gi-closed) and g*b-closed sets(resp.gb-closed) and g*d-closed sets(resp.gd-closed). We also established the independency between the notions g*i-closedness (resp.gi-closedness) and g*d-closedness (resp.gd-closedness).

Mathematical Modeling of Higher Overtone Vibrational Frequencies in Dichlorine Monoxide

Sreenivas Teppala*

Abstract

This study presents the calculation of stretching vibrational frequencies for the triatomic molecule dichlorine monoxide (Cl₂O), explicitly focusing on the fourth, fifth, and sixth overtones. Using a Lie algebraic framework, we provide a detailed mathematical modeling approach to predict these higher overtone frequencies accurately. The results demonstrate the effectiveness of the Lie algebraic method in capturing the complex vibrational behavior of Cl₂O, offering valuable insights into its vibrational spectra.

Optimizing Capsule Endoscopy Detection: A Deep Learning Approach with L-Softmax and Laplacian-SGD

Jamshaid Rahman*

Abstract

Capsule Endoscopy has emerged as a non-invasive diagnostic tool for gastrointestinal diseases, yet efficient disease classification remains a challenge due to inherent complexities in image analysis. Also, the extensive time required for manual examination of capsule endoscopy led researchers and clinicians to seek time-efficient automated detection methods. This is where the profound advantages of Deep Learning (DL) become crucial. This research proposes a novel approach combining L-Softmax with Laplacian Smoothing Stochastic Gradient Descent (LSSGD) in ResNet architecture to enhance disease classification accuracy in capsule endoscopy images from Kvasir dataset. The L-Softmax function is integrated within a DL framework, facilitating better class separation and feature representation. Additionally, LSSGD is employed to mitigate overfitting and enhance model generalization. Experimental results show that our methodology is stable and easy to utilize in capsule endoscopy.

KERNEL IDEALS IN SEMIGROUPS

Sujatha Gaadi*

Abstract

In this paper the concepts of ∗-ideals, strong ideals, ∗- congruences and kernel ideals are introduced in a pseudo-complemented semigroup and discussed certain properties of these. Some equivalent conditions for an ideal of a pseudo-complemented semigroup to become a kernel ideal are obtained. The lattice structure of strong ideals is discussed.

Modeling the Dynamics of Covid-19 with the inclusion of Treatment, Vaccination and Natural Cure

Kiran Kumar Ganne*

Abstract

In this paper, a Covid-19 pandemic model with five compartments is presented. Model assumptions, flowchart and the system of model equations are included. It is found that the solutions for the model equations exist and they are unique, positive and bounded. Hence, the present model is termed as mathematically well-posed and biologically meaningful. Mathematical analysis, sensitivity analysis are conducted in order to draw meaningful conclusions. Sensitivity analysis on the model equations reveal that the immunity loss has a positive impact while vaccination and treatment have negative impact on the effective reproduction number. The research results assert that the pandemic can be kept under control by enhancing vaccination and treatment facilities and similarly by implementing suitable methods to reduce loss of immunity. Outcomes of both qualitative and quantitative analyses are included and described elaborately. Disease free equilibrium point is identified and it’s local and global stability analyses are conducted using powerful techniques like Routh-Hurwitz criteria and Lyapunov function method. Detailed description of the model is presented in the text of the paper lucidly.
