Stability and numerical analysis via non-standard finite difference scheme of a nonlinear classical and fractional order model
(Elsevier B.V., 2023)
In this paper, we develop a new mathematical model for an in-depth understanding of COVID-19 (Omicron variant). The mathematical study of an omicron variant of the corona virus is discussed. In this new Omicron model, we ...
A new approach to fractional differential equations
(Serbian Society of Heat Transfer Engineers, 2023)
In this work, we define fractional derivative of order ς > 0, with no restrictions on the domain of the function, and give its geometry. We derive some rules and properties for the proposed new approach and show that if ...
Coupled System of Fractional Impulsive Problem Involving Power-Law Kernel with Piecewise Order
(MDPI, 2023)
In this research paper, we study a coupled system of piecewise-order differential equations (DEs) with variable kernel and impulsive conditions. DEs with variable kernel have high flexibility due to the freedom of changing ...
Using advanced analysis together with fractional order derivative to investigate a smoking tobacco cancer model
(Elsevier B.V., 2023)
This research manuscript is devoted to investigate a smoking tobacco cancer model by applying some advanced techniques based on second derivative. The snuffing class is included in the construction of our model. The stability ...
A Survey of Indoor and Outdoor UAV-based Target Tracking Systems: Current Status, Challenges, Technologies, and Future Directions
(Institute of Electrical and Electronics Engineers Inc., 2023)
Due to their distinctive features, unmanned aerial vehicles (UAVs) have been recently exploited to support a wide range of applications. The features include low maintenance cost, compact size, and excellent capability of ...
On Subspace Codisk-Cyclicity
(University of Baghdad-College of Science, 2023)
Let N be a subspace of an infinite dimensional complex separable on a Hilbert space ℋ. The operator T ∈ ℬ(ℋ) is said to be N-codisk-cyclic, if there is a nonzero vector y in ℋ, then N ∩ {βTn y: β ∈ ℂ, |β| ≥ 1, n ∈ ℕ} is ...
Frequency Control of a Realistic Dish Stirling Solar Thermal System and Accurate HVDC Models Using a Cascaded FOPI-IDDN-Based Crow Search Algorithm
(Hindawi Limited, 2023)
Unbalancing the real power in power system leads to fluctuation in system frequency which can cause the several negative effects on the performance and reliability of the interconnected power system. Therefore, to deal ...
Existence theory and numerical simulations of variable order model of infectious disease
(Elsevier B.V., 2023)
This study uses variable order differentiation and integration to investigate the disease dynamical model of COVID-19. Here, we update the results of the qualitative and quantitative analysis. We obtain necessary conclusions ...
Revolutionizing Small-Scale Retail: Introducing an Intelligent IoT-based Scale for Efficient Fruits and Vegetables Shops
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
In the bustling streets of Pakistan, small-scale fruits and vegetables shops stand as vital hubs of daily life. These humble establishments are where people flock to satisfy their everyday needs. However, the traditional ...
On a SEIR-type model of COVID-19 using piecewise and stochastic differential operators undertaking management strategies
(American Institute of Mathematical Sciences, 2023)
In this work, an epidemic model of a susceptible, exposed, infected and recovered SEIR-type is established for the distinctive dynamic compartments and epidemic characteristics of COVID-19 as it spreads across a population ...
