Random sampling is a technique for signal acquisition which is gaining popularity in practical signal processing systems. Nowadays, eventdriven analog-to-digital converters make random sampling feasible in practical applications. A process of random sampling is defined by a sampling pattern, which indicates signal sampling points in time. Practical random sampling patterns are constrained by AD...

Computer-aided teaching tools have turned out to be an indispensable element of both classroom lectures and laboratory experiments. The application of market-ready mathematical and database programming software for teaching engineering course outline is well appreciated. This paper presents the utilization of LabVIEW (Laboratory Virtual Instrument Engineering Workbench) in introducing the featu...

Conditions sufficient for a quantum dynamical semigroup (QDS) to be unital are proved for a class of problems in quantum optics with Hamiltonians which are self-adjoint polynomials of any finite order in creation and annihilation operators. The order of the Hamiltonian may be higher than the order of completely positive part of the formal generator of a QDS. The unital property of a minimal qua...

Abstract A simple novel method for random number generation is presented, based on a Raman fiber laser. This laser built in half-open cavity scheme, closed one side by narrow-linewidth 100 mm Bragg grating. The interaction between the randomly excited lasing modes of this laser, addition to nonlinear effects such as modulation instability, allow bits at rates up 540 Gbps with minimal post proce...

In this research, a new technetium-99m generator has been developed with addition of Cerium oxide to alumina column.  The adsorption behaviors of 99Mo in the form of molybdate and 99mTc in the form of pertechnetate on CeO2/Al2O3 was investigated and showed that the adsorption capacity of molybdate on this generator is higher than usual generator using Al2O3. Ceric ions were selected as an addit...

  In this paper, we present some important dynamical concepts on uniform space such as the minimal systems, shadowing, and strong shadowing. We explain definitions theorems definition expansive, weak generator, proof of for them. prove that if  be a homeomorphism compact  then  has shadowing only has so also show  and two homeomorphisms spaces ,  is conjugacy from ...
