In this work the equations of motion of a Solid State Wave Gyroscope (SWG) with rotary thin cylindrical shell resonator is analyzed using the shell and plates elasticity theory. The gyroscope conversion factor found in this analytical study corresponds with the experimental results obtained and listed in the References. The function of the SWG to measure the angular velocity or the rotating ang...

We study the formation of the (noncommutative) Schwarzschild black hole from collapsing polytropic and Chaplygin gas shells. We show that the collapsing shell forms either a black hole or a naked singular shell with the help of the pressure. A slight modification of collapsing shell that consists of the smeared gravitational sources can form a noncommutative Schwarzschild black hole while this ...

INT Workshop Advances in many-body theory: from nuclei to molecules

The theoretical model, developed by Khare model, has been modified to calculate the total cross sections for K-shell, L-shell and M-shell ionization of uranium (Z=92) atom due to electron impact at incident electron energy from ionization threshold to 1 GeV. The various calculated cross sections are in remarkable agreement with available experimental data and other theoretical cross sections. P...

We present an analysis for a mixed finite element method for the bending problem of Koiter shell. We derive an error estimate showing that when the geometrical coefficients of the shell mid-surface satisfy certain conditions the finite element method has the optimal order of accuracy, which is uniform with respect to the shell thickness. Generally, the error estimate shows how the accuracy is a...

We describe a route to the development of novel PtNiN core-shell catalysts with low Pt content shell and inexpensive NiN core having high activity and stability for the oxygen reduction reaction (ORR). The PtNiN synthesis involves nitriding Ni nanoparticles and simultaneously encapsulating it by 2-4 monolayer-thick Pt shell. The experimental data and the density functional theory calculations i...

In this paper we develop a theoretical model in order to understand co-movements between asset returns and consumption over short and long horizons. We present an intertemporal general equilibrium model featuring two types of shocks: "small", frequent and disembodied shocks to productivity and "large" technological innovations, which are embodied into new vintages of the capital stock. The latt...

In this paper, we analyze a few physical characteristics of gravastar with cylindrical geometry in $f(R,T)$ theory, where $R$ is the Ricci scalar and $T$ trace energy-momentum tensor. The generally considered to be substitute black hole three different regions. present work, examine formulation gravastar-like structures theory. By using Darmois Israel matching conditions, formulate mass functio...

In a previous paper [Berger et al., PNAS 91 7732, 1994], a theory of virus shell formation was proposed in which shell assembly is directed by local interactions of the coat and sca olding subunits. This theory requires that the same chemical subunits assume di erent, stable conformations depending on their position in the shell. During assembly, the conformation of a protein subunit dictates t...
