Abstract .The complex interplay between thermal, hydrodynamic, and electromagnetic, forces governs the evolution of multi-phase systems in high technology applications, such as advanced manufacturing and fusion power plant operation. In this work, a new formulation of the time dependent magnetic induction equation is fully coupled to a set of conservation laws for multi-phase fluid flow, energy transport and chemical species transport that describes melting and solidification state transi...

Abstract . We propose a novel and simple method for the laser isotope separation of 176 Lu a precursor for the production of 177 Lu medical isotope. The physics of the laser-atom interaction has been studied through the dynamics of the atomic level populations using the density matrix formalism. It has been shown that a combination of cw excitation lasers and pulsed ionization laser can be used for the laser isotope separation of 176 Lu. The optimum conditions for the efficient and s...

Introduction .Global navigation satellite systems (GNSS) can provide all-weather worldwide positioning services and have become the preferred positioning and navigation technology in various fields (Krüger et al. 1994 ; Hein 2020 ). However, the GNSS signal is actually ineffective for positioning in many GNSS-denied environments since it is susceptible to attenuation effects (Kuusniemi and Lachapelle 2004 ). Pseudolites are ground-based GNSS-like signal transmitters which can be easil...

1. Introduction . Functional diffuse optical tomography (fDOT), as an advanced implementation of functional near-infrared spectroscopy (fNIRS), is a fast-developing non-invasive quantitative brain imaging technique. Nowadays, fDOT has been becoming a complementary or alternative tool to functional magnetic response imaging (fMRI) and electroencephalogram (EEG) owing to its combination of potential portability, strong environmental robustness, and reasonable temporal and spatial resolution [ ...

1. Introduction . The technological advance has allowed to design and fabricate optical surfaces with different shapes, beyond of the traditional surfaces with symmetry of revolution, such as conics and other aspherical surfaces. These new shapes are called freeforms, these are useful to reduce aberrations, dimensions and weight in optical system better than conventional optical systems does, because they have more degrees of freedom, i.e., lacking of axial or translational symmetry; therefor...
