Abstract This article is concerned with the optimal mild solution and optimal control for stochastic Caputo fractional multi-valued impulsive non-autonomous differential equations with delayed force term and fractional B...

Abstract A compartmental mathematical model was developed to examine the transmission dynamics of chikungunya, integrating media awareness and optimal control strategies. Both asymptomatic and symptomatic infectious cate...

Introduction Overweight and obesity are major global public health challenges and increase the risk of type 2 diabetes, dyslipidaemia, hypertension and cardiovascular disease. Exercise is a safe and cost-effective non-ph...

ABSTRACT Background and Aims Delayed healing in diabetes‐related foot ulcer (DFU) remains a clinical challenge, and regulating wound pH may offer a promising solution due to its significant role in healing. This study ...

ABSTRACT Introduction Diabetic neuropathy, the most common long‐term complication of diabetes, frequently presents as painful diabetic peripheral neuropathy (pDPN), significantly impairing patients' quality of life. Pr...

Abstract The growing deployment of grid-connected voltage source inverters (GC-VSIs) in the smart grids poses some significant issues that include harmonic distortion, grid impedance fluctuations, nonlinear loading, and ...

Abstract Purpose Perinatal complications can occur in gestational diabetes mellitus (GDM) despite adequate metabolic control and standard diagnostics. Metabolic alterations can cause structural and functional changes in ...

Microgrids have emerged as an effective solution for integrating distributed energy resources, providing operational flexibility by their ability to operate in grid-connected and islanded modes. However, the high penetra...

The increasing penetration of renewable energy sources (RES) reduces power system inertia, causing severe frequency excursions following disturbances. Conventional Automatic Generation Control (AGC) using fixed-gain cont...

Introduction. In recent days, electric vehicles, robotics and in many control system applications, permanent magnet synchronous motors (PMSMs) are widely utilized. Problem. Due to non-linear behavior of system, external ...

Aims: The aims were to assess the influence of tibial bone mineral density (BMD) and cement viscosity on cement mantle thickness in total knee arthroplasty (TKA), and to determine whether BMD is a more dominant factor th...

Background. Type 2 diabetes is a chronic metabolic disorder associated with impaired insulin secretion and insulin resistance, leading to persistent hyperglycemia and multiple complications. Despite advances in pharmacot...

Rice production faces major challenges, notably unpredictable weather and pest attacks. The duration of sun drying depends on the climate and weather: if the weather is clear and the sun shines fully throughout the day, ...

In controlling DC-DC buck converters, the issue of input uncertainties as well as load uncertainties is one of the important challenges in controller design. This paper addresses this issue as well as presents a new robu...

IntroductionA research gap exists regarding the association between non-optimal ambient temperature (NOAT) and early childhood development (ECD) in low- and middle-income countries (LMICs). This study investigates the as...

Abstract Background Digital health interventions offer a promising opportunity to innovate traditional cessation services. Multi-component digital approaches show potential for greater effectiveness than traditional meth...

Mobility-as-a-Service (MaaS) orchestration faces critical challenges in managing the Service Quality Index (SQI), Fleet Utilization Ratio (FUR), and Dynamic Pricing Index (DPI) under uncertain and time-varying urban dema...

Abstract This paper proposes an integrated and optimally tuned photovoltaic water pumping system (PVWPS) with high performance and operational stability under variable climatic conditions. The pumping process starts with...

This paper proposes an innovative model-free deep reinforcement learning-based controller (RL-C) for a grid-connected 5-level packed-U-cell (PUC5) multilevel inverter (MLI). The controller is designed to deliver a high-q...

Abstract Unmanned aerial vehicles, particularly quadrotors, present significant control challenges due to their nonlinear, underactuated, and coupled dynamics. This paper presents a comprehensive modeling approach for a ...

Source-grid-load-storage coordinated operation control is an operation mode and technology that can maximize the utilization of energy resources, and can economically, efficiently and securely improve the power dynamic b...

Indoor hydroponics offers a promising pathway toward sustainable urban agriculture, but its effectiveness depends on precise environmental control. This study presents a compact, energy-efficient hydroponic system that u...

This study presents pioneering research addressing the challenge of surrounding rock control in gob-side entry retaining by roof cutting under the conditions of a gently inclined coal seam with an extra-thick main roof r...

ObjectiveLimestone water hazards in coal seam floors represent one of the two primary categories of mine water hazards in China. Limestone aquifers are generally characterized by abundant static water reserves and consid...
