ABSTRACT: Globally, electronics cards, including smart and magnetic cards, are utilized for a variety of purposes but not limited to security, personnel identification, electronic payment, and electronic voting. This study, which is at the University of Cross River State, offers an electronic card-based solution to the issue of lecture attendance in higher education. Our approach is based on an embedded Quick Response [QR] Code identification card that if scanned during lectures can authenticate the availability of a student using cloud services. This system could expedite the......

ABSTRACT: This study investigates the spatial distribution and heterogeneity of Aerosol Optical Depth (AOD) and its influencing factors: burned area (BA), dust (DU), sea salt (SS), and black carbon (BC), across Nigeria from 2011 to 2019. The work analyzed seasonal patterns and the interactions between these variables using Geodetector model. Results show distinct seasonal variations in AOD and its contributors, with high dust concentrations in the north during the DJF season suggestive of the influence from the Harmattan winds originating from.....

ABSTRACT: According to the spacetime conception of the universe, spacetime, energy and mass form a continuum, such that st = mE. Given that st refers to spacetime, m stands for mass, and E is energy, the spacetime conception of the universe states that spacetime is equal to mass multiplied by energy. The law st = mE presents a holistic conception of the universe because it successfully accounts for the basic insights of both relativity theory and quantum mechanics, aiming to reconcile between classical physics and the weird behavior of the quantum world.......

ABSTRACT: Tropical cyclones (TCs) pose significant threats to human lives and property, highlighting the critical importance of accurate forecasts and timely warnings for coastal communities. This study evaluates TC intensity prediction using the Weather Research and Forecasting (WRF) model, focusing on three specific TCs—Amphan (2020), Bulbul (2019), and Titli (2018) over the Bay of Bengal (BoB). The selected TCs are simulated across various forecast lead times (LT) using two two-way interactive nested domains. Global Data Assimilation System (GDAS)/Final......

ABSTRACT: It is suggested by some scientists that Planck Units including Planck Length, Planck Time and Planck Mass are representing the fundamental physical scales in the universe such as the size and mass of God's particle, and the formation time of the universe. A model of critical size cluster of gravitons is proposed intentionally to explain the meanings of Planck Units based on Graviton Radiation and Contact Interaction Theory. As a result, Planck Length,.......

ABSTRACT: Magnetic Pulsations recorded on the ground are the signatures of the integrated signals from the earth's magnetosphere. Pc4 geomagnet-ic pulsations are quasi-sinusoidal variations in the earth's magnetic field in the period range 45-150 seconds. The magnitude of these pulsations ranges from fraction of a nano Tesla (nT) to several nT. Although these pulsations can be observed in a number of ways, yet the application of ground-based magnetometer arrays has proven to be the most successful methods of studying the spatial structure of hydromagnetic waves in the earth's magnetos-phere. The solar wind provides the energy for the earth's magnetospheric.....
