Several reviews concerning the EPR of the paramagnetic transition-metal ions in crystals are now available, either as periodic reports published in the Magnetic Resonance Review, or in books [1,2,3] and review papers [4, 5]. Such paramagnetic centers are usually observed in the as grown crystals, the paramagnetic state being the normal valency state of the impurity in the crystal-host lattice. ...

The present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using Markov Birth-Death process and probabilistic approach. In present paper, the feed water system consists of four subsystems. After drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

This work introduces a new type of a Petri net. This is called a Matrix Transition Net. The Matrix Transition net deals with the modeling of modern distributed complex computer and communication systems. The major features are that for the inputs and outputs of this net, matrices are used instead of places as in standard place transition Petri nets. This increases the modeling power and express...

A Markov chain is a natural probability model for accounts receivable. For example, accounts that are “current” this month have a probability of moving next month into “current”, “delinquent” or “paid-off” states. If the transition matrix of the Markov chain were known, forecasts could be formed for future months for each state. This paper applies a Markov chain model to subprime loans that app...

The orientational phase diagram and ordering of guest liquid crystalline (LC) rods in a host liquid crystalline polymer (LCP) matrix quenched below the glass transition is determined by field theory. Microscopic anisotropic interactions can align the LC rods to each other and also align LCP matrix side chains and the LC rods in the plane normal to the local LCP chain contour. Our numerical anal...

When a transition probability matrix is represented as the product of two stochastic matrices, swapping the factors of the multiplication yields another transition matrix that retains some fundamental characteristics of the original. Since the new matrix can be much smaller than its precursor, replacing the former for the latter can lead to significant savings in terms of computational effort. ...

fept nanoparticles with thermally stable room-temperature ferromagnetism are investigated. the monodisperse nanoparticles are prepared by chemical synthesis and a salt-matrix annealing technique. structural and magnetic characterizations confirm the phase transition from the disordered face-centered cubic structure. in this paper, 3 nm fept nanoparticles are first synthesized by superhydride re...
