In this paper, we proposed a new two-parameter lifetime distribution with increasing failure rate, the complementary exponential geometric distribution, which is complementary to the exponential geometric model proposed ...

It is well known in NSR string theory, that vertex operators can be constructed in various pictures. Recently this was discussed in the context of pure spinor formalism. NSR picture changing operators have an elegant ...

In this paper we present a unified Lagrangian–Hamiltonian geometric formalism to describe time-dependent contact mechanical systems, based on the one first introduced by K. Kamimura and later formalized by R. Skinner and ...

The finite element method FEM is an important tool used in various areas of science, where partial differential equations need to be discretized. The problem's domain is approximated by means of a geometric element partition, ...

Based only on the parallel-transport condition, we present a general method to compute Abelian or non-Abelian geometric phases acquired by the basis states of pure or mixed density operators, which also holds for nonadiabatic ...
