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 ...
A Novel Hybrid Approach for Power Quality Improvement in a Vehicle-to-Grid Setup Using Droop-ANN Model
(Hindawi Limited, 2023)
The integration of electric vehicles (EVs) in the power grid has attracted considerable attention due to its potential benefits, such as demand response and power quality improvement. However, the intermittent and unpredictable ...
Metamaterial inspired electromagnetic bandgap filter for ultra-wide stopband screening devices of electromagnetic interference
(Nature Research, 2023)
Presented here is a reactively loaded microstrip transmission line that exhibit an ultra-wide bandgap. The reactive loading is periodically distributed along the transmission line, which is electromagnetically coupled. The ...
A novel data balancing approach and a deep fractal network with light gradient boosting approach for theft detection in smart grids
(Elsevier Ltd, 2023)
Electricity theft is the largest type of non-technical losses faced by power utilities around the globe. It not only raises revenue losses to the utilities but also leads to lethal fires and electric shocks at distribution ...
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 ...
A Distributed and Secure Self-Sovereign-Based Framework for Systems of Systems
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Security and privacy are among the main challenges in the systems of systems. The distributed ledger technology and self-sovereign identity pave the way to empower systems and users’ security and privacy. By utilizing both ...
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 ...
FireXnet: an explainable AI-based tailored deep learning model for wildfire detection on resource-constrained devices
(Springer Science and Business Media Deutschland GmbH, 2023)
Background: Forests cover nearly one-third of the Earth’s land and are some of our most biodiverse ecosystems. Due to climate change, these essential habitats are endangered by increasing wildfires. Wildfires are not just ...
Brain Tumor Classification from MRI Using Image Enhancement and Convolutional Neural Network Techniques
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
The independent detection and classification of brain malignancies using magnetic resonance imaging (MRI) can present challenges and the potential for error due to the intricate nature and time-consuming process involved. ...
