31. EXISTENCE OF SOLUTION OF IMPULSIVE QUANTUM STOCHASTIC DIFFERENTIAL INCLUSIONS USING NON FIXED POINT APPROACH

ABIMBOLA Latifat Adebisi (First Technical University, Ibadan)

27/05/2024, 15:25

Applied mathematics

We observed that Impulsive Quantum Stochastic Differential Inclusion (IQSDI) may not have solution even if it is Lipschitz continuous because of the limiting condition imposed on the impulsive term $t_k .$ We impose an extra regularity condition on $t_k $ and establish solution using minimal selection theorem. QSDI in this work is in the framework of Hudson and Parthasarathy developed quantum...

Timileyin Okoya

27/05/2024, 15:35

Computer Science

This paper explores predictive modelling, a mathematical technique used to analyse data patterns for forecasting future events or outcomes. Predictive modelling is a crucial component of predictive analytics, a data analytics discipline that employs machine learning and data mining methods to forecast activity, behaviour, and trends using both current and historical data. Initially, the paper...

35. A Trigonometrically-Fitted Four Step Method for solving Oscillatory Second Order Ordinary Differential Equations

Oluwasemire Adegboro (University of Medical Sciences, Ondo)

27/05/2024, 15:45

Applied mathematics

A continuous implicit trigonometrically-fitted four-step method (CITFFM) for solving oscillatory second order ordinary differential equations (ODEs) is developed in this paper. The CITFSM is generated by collocation and interpolation techniques through the use of a combination of power series and trigonometric function as approximate basis equation. For implementation purpose, an implicit...

44. Biomechanical Analysis of Hemodynamic Muscular Pressure on the Arterial Blood Vessel: Insights from Computational Modeling

Mr Olutosoye Taiwo (AFE BABLOLA UNIVERSITY ADO EKITI, EKITI STATE NIGERIA)

27/05/2024, 15:55

Mechanical Engineering

High blood pressure, also known as hypertension, is a common medical condition where the force of blood against the walls of the arteries is consistently too high. During the last 100 years, pathological methods have been used to explain different ways that recapitulate the unique features of muscles and how they relate to the arterial blood vessel. The mechanical characterization of pressure...

47. Temperature oxidation of double combustible reaction and thermal ignition in a concentric cylinder with diverse boundary constraints

Dr S. O. Salawu (Bowen University, Iwo)

27/05/2024, 16:05

Applied mathematics

Chemical species undergoing spontaneous reactions and temperature oxidation of materials are useful in explosion safety, propulsion detonation and chemical synthesis. Thus, this study considers the dynamics of temperature oxidation of a two-step exothermic combustion and thermal ignition in a concentric isothermal cylinder with diverse boundary constraints. With constant thermal reactant...

Computer Engineering

Analog circuit design for nonlinear programming has been widely studied in the literature (Dennis, 1959;
Kennedy and Chua, 1988; Tank and Hopfield, 1986; Wilson, 1986). However, recent advances in edge computing
and in model predictive control have led to a resurgence of interest in analog programming circuits (Vichik and
Borrelli, 2014; Vichik et al., 2016; Bena et al., 2023). We develop...

43. Modelling HIV Superinfection with Two Unique Viral Strains

Matthew Ayodeji Ogunniran (University of Ilorin, Ilorin)

27/05/2024, 16:25

HIV superinfection, the acquisition of a second distinct viral strain in an individual already infected, presents challenges to HIV management and vaccine development. Understanding the dynamics and implications of superinfection is crucial for advancing HIV research and developing more effective prevention and treatment strategies. While HIV superinfection is recognized, the mechanisms,...

72. An optimal control intervention for the interrelated dynamics of TB transmission in humans and animals amidst seasonal flux

James Akingbade (University of Ilorin)

27/05/2024, 16:35

Biology

Tubercuosis(TB)is a global health concern,affecting both humans and animals.This paper
provides a dynamic model to anayze the complicated dynamics of tuberculosis transmission,
taking into account human animal interactions and a saturated incidence rate with seasonal
changes.Furthermore,the model accounts for the efficiency of measures targeted at reducing the
spread of...

54. Induced Partial and Mixed synchronization in Chain-Fractance system

Mr Joshua Adeyeri

27/05/2024, 16:45

A general procedure for targeting and controlling synchronization in chain-fractance configuration is designed bidirectionally and unidirectionally. The appropriate open-plus-closed-loop coupling criterion are employed to induce mixed and partial synchronization, respectively. Transitions from anti-synchronization, amplitude death and complete synchronization were realized by varying the...
