Semiclassical Approach to the Nonlocal Kinetic Model of Metal Vapor Active Media

“…Here, Φ( x, t, D) is a common element of the class, the real function ϕ( ξ, t, D) belongs to the Schwartz space S in variables ξ, smoothly depends on t and regularly depends on √ D as D → 0, ∆ x = x − X(t, D). The real smooth functions X(t, D) and S(t, D), characterizing the class P t D , regularly depend on √ D as D → 0 and are to be determined when constructing a solution to the Equation (7).…”

“…In the asymptotic estimates, the leading term gives more insight into the solution of the problem. Therefore, in this work, we focus on constructing the leading terms of asymptotic solutions of the kinetic Equation (7).…”

“…The semiclassical approach developed in [30][31][32] can be applied to Equation (7) when the following moments exist for its solution u( x, t, D) ∈ P t D :…”

“…In MVAM, mainly metal atoms are ionized, and the buffer gas practically does not contribute to the concentration of the electron gas due to the much higher ionization energy. In a number of works (see, for example, [6][7][8][9][10]), active media were investigated, where neon acted as a buffer gas, and vapors of copper and its halides did as an active substance.…”

Speckle pattern processing by digital image correlation

“…The objects under control can be living organisms as well as various machine parts during the process of their manufacturing or their operation. Promising technics of remote control and at the same time nondestructive testing are the optical methods, and specifically methods based on the use of coherent radiation [1][2][3][4][5][6].…”
