The full-bridge submodules (FB-SMs) in hybrid modular multilevel converters need to absorb the enormous energy stored dc side and arm inductors during fault blocking, which may lead severe overvoltage. An energy-absorbing branch (EAB) composed of metal oxide varistor (MOV) thyristors is proposed this letter. No extra power loss produced by EAB normal operation. can a part reduce absorbed FB-SMs...

Let $G$ be a group with identity $e$. $R$ $G$-graded commutative ring and $M$ graded $R$-module. In this paper, we introduce the concept of classical strongly 2-absorbing second submodules modules over rings. A number results concerning these classes their homogeneous components are given.

The submodule construction problem (SCP) as stated and formulated by Merlin and Bochmann [P. Merlin, G.V. Bochmann, On the construction of submodule specification and communication protocols, ACM Trans. Prog. Lang. Sys., 5(1) (1983) 1–25] is considered: given the specification of a system (module) and that of its n 2 1 submodules, determine the specification of the nth submodule that together w...

Each symplectic group over the field of two elements has two exceptional doubly transitive actions on sets of quadratic forms on the defining symplectic vector space. This paper studies the associated 2-modular permutation modules. Filtrations of these modules are constructed which have subquotients which are modules for the symplectic group over an algebraically closed field of characteristic ...

We investigate the maximal finite length submodule of Breuil–Kisin prismatic cohomology a smooth proper formal scheme over $p$ -adic ring integers. This governs pathology phenomena in integral theories. Geometric applications include control, low degrees and mild ramifications, (1) discrepancy between two naturally associated Albanese varieties characteristic , (2) kernel specialization map éta...
