We use the idea of nonstandard finite difference methods to derive the discrete variational integrators for multisymplectic PDEs.We obtain a nonstandard finite difference variational integrator for linear 1m SMA wave equation with a triangle discretization and two nonstandard finite difference variational integrators for the nonlinear Klein-Gordon
The study investigates the concentration of heavy metals in various lipsticks sold in Ghana and assesses the potential health risks associated with their use.A total of 12 lipstick samples were analyzed using an X-ray fluorescence (XRF) analyzer for metals, including chromium (Cr), manganese (Mn), nickel (Ni), copper (Cu), cadmium (Cd), and lead (P
Visual odometry is the task of estimating the trajectory of the moving agents from consecutive images.It is a hot research topic both in robotic and computer vision communities and facilitates many applications, such as autonomous driving and virtual reality.The conventional odometry methods predict the trajectory by utilizing the multiple view geo
A novel non-contact vital-sign sensing algorithm for use in cases of multiple subjects is proposed.The approach uses a 24 GHz frequency-modulated continuous-wave Doppler radar with the parametric spectral estimation method.Doppler processing and spectral estimation are concurrently implemented 1m SMA to detect vital signs from more than one subject
This article describes a task for construction of a subject classification framework under the background of analyses of the researches of Library and Information Science (LIS).The proposed framework covers the possible research issues including those influenced by the information technology and network techniques.We first investigate the existing
