We review direct photons in the phenomenology of nuclear collisions at relativistic energies. Direct carry information about space–time evolution because QCD medium is transparent against colorless particles. After a status summary theoretical and experimental studies, transverse momentum spectra azimuthal anisotropies are studied context hydrodynamic modeling with emphasis on pre-equilibrium p...

The present study deals with the analyses of direct reduction kinetics during hydrogen industrial iron oxide pellets. Various types pellets different percentage total content and metal oxides are examined. They reduced at temperatures pressure (700–1100 °C 1–6 bar) in atmosphere. behavior is described terms time to reduction, rate constant. All obtained results analyzed through employment a com...

Independent Component Analysis (ICA) is a fundamental method for Blind Source Separation (BSS). Classical ICA takes data matrix input formed by vector data. This paper focuses on BSS with third-order tensor data, such as 2D images. Two approaches exist this problem. The first approach reshapes each into to apply classical ICA, structural information lost. second unfolds along different modes pe...
