Review on UV – Visible Spectroscopy and HPLC
Abstract: Like Fourier-transform infrared spectroscopy, UV-visible spectroscopy is used to determine the purity of pharmaceutical compounds. Many substances have chromospheres, which absorb certain wavelengths of ultraviolet or visible light. Using the Beer–Lambert equation, the absorption of spectra obtained from these samples at given wavelengths can be directly related to the sample concentration. Normally, UV and UV-visible spectra are recorded at high and low pH, and the results of both are compared …

Effect of Internal Heat Generation on the Onset of Rayleigh-Bѐnard Chandrashekar Convection in a Micropolar Fluid with Maxwell Cattàneo Law
Abstract: AbstractThe effect of result from the substitution of the classical Fourier law by the nonclassical Maxwell-Cattàneo law and influence of internal heat generation on the Rayleigh-Bѐnard Chandrashekar internal heat generation parameter has a significant impact on the thermal mode making the system unstable. The eigen value is obtained for free-free, rigid-free and rigid-rigid velocity boundary combinations with isothermal temperature on the spin-vanishing boundaries. The influence of various micropolar fluid parameters …

A Parallel Unit Encoding Stage for BCWT using GPGPU
Abstract: AbstractA backward coding of wavelet trees (BCWT) algorithm begins the coding process from the lower-level to the higher-level of the wavelet tree. While processing, it builds up the maximum quantization levels of the descendant (MQD) map and maximum quantization level (MQL) by the support of the wavelet coefficients of the corresponding image. In the processes of making the serial encoding stages into parallel stages, primarily we deal with a prominent …

Study of Phase Velocity and Magneto Plasmon Dispersion on the Surface of Carbon Nanotubes in Low Energy State
Abstract: Several authors have worked on theoretical and experimental plasmon excitations. The researchers have been studying the dispersion relation of magneto plasmon in the low energy state on a cylindrical surface of carbon nanotube obtained with the help of linear-angular momentum transfer. Here, we demonstrate the Dirac-like Hamiltonian equation for carbon nanotubes in the presence and absence of a parallel applied magnetic field. We assume the cylindrical carbon nanotube is infinitesimally …

Analysis of the Impact of Seabed Earthquakes on Coastal Structures and Foundation Design
Abstract: Earthquakes in the seabed occur with varying magnitudes. Seabed earthquakes cause a rapid rise in water levels, which can lead to flooding and structural damage. Therefore, when designing buildings near the seashore, it is essential to account for the additional load on columns due to water thrust. Earthquakes occurring at the seabed generate intense ground acceleration of varying magnitudes, significantly affecting water levels and inducing destructive flooding along coastal regions. …

Physical Activity Based Vehicle Control Using ESP32
Abstract: This paper introduces an optimized and reliable project named Move-Buddy, a device that encourages physical movement in children. This is a way of engaging children in a game which causes them to move their body in different positions (e.g., wave their arms and move their legs) for the device to move forward, backward, left, and right according to the action performed by the child. The device uses multiple sensors placed …

Effect of Throughflow on the Onset of Electro-Thermo Convection in a Micropolar Fluid with Maxwell-Cattaneo Law
Abstract: AbstractThe effect of throughflow on the onset of Electro-thermo convection in a micropolar fluid with Maxwell-Cattaneo law is studied using the linear theory. The eigenvalue is obtained for free-free, rigid-rigid and rigid-free velocity boundary combinations with isothermal and adiabatic on the spin-vanishing boundaries using galerkin technique. The influence of Peclet number, Electric Rayleigh number and various micropolar fluid parameters on the onset of convection has been analyzed. It is found …
