Quantization of bosonic fields with two mass and spin states
We investigate bosonic fields possessing two mass and spin states. The
density matrix in the first order formalism is obtained. The quantization of
fields in the first order formulation is performed and propagators are found.Comment: 9 page
Transition Probability to Turbulent Transport Regime
Transition phenomena between thermal noise state and turbulent state observed
in a submarginal turbulent plasma are analyzed with statistical theory.
Time-development of turbulent fluctuation is obtained by numerical simulations
of Langevin equation which contains hysteresis characteristics. Transition
rates between two states are analyzed. Transition from turbulent state to
thermal noise state occurs in entire region between subcritical bifurcation
point and linear stability boundary.Comment: 9 pages, 6 figures, to be published in Plasma Phys. Control. Fusio
Simulation of Energy Consumption in Multi Cluster Wireless Sensor Networks
Energy conserving protocols in wireless sensor networks (WSNs), such as S-MAC, introduce multi-cluster network. The border nodes in multi cluster WSNs have more active time than the other nodes in the network; hence have more energy depletion rate. Since battery replacement in most networks is considered difficult, one or more nodes running out of energy prematurely will affect the network connectivity and decrease the overall network performance severely. This paper aims to (1) analyze the energy consumption in a multi-cluster sensor network and compare it to the single cluster scenario (2) investigate the merging time in a single cluster network. The result shows that, in average the energy needed to deliver a packet in the multi cluster networks is about 150% more than the energy needed in the single cluster networks. Moreover, the merging time in the single cluster network using schedule offset as the merging criteria in average is slightly smaller than one in the network using schedule ID as the merging criteria
Hamilton-Jacobi quantization of singular Lagrangians with linear velocities
In this paper, constrained Hamiltonian systems with linear velocities are
investigated by using the Hamilton-Jacobi method. We shall consider the
integrablity conditions on the equations of motion and the action function as
well in order to obtain the path integral quantization of singular Lagrangians
with linear velocities.Comment: late
A momentum-space Argonne V18 interaction
This paper gives a momentum-space representation of the Argonne V18 potential
as an expansion in products of spin-isospin operators with scalar coefficient
functions of the momentum transfer. Two representations of the scalar
coefficient functions for the strong part of the interaction are given. One is
as an expansion in an orthonormal basis of rational functions and the other as
an expansion in Chebyshev polynomials on different intervals. Both provide
practical and efficient representations for computing the momentum-space
potential that do not require integration or interpolation. Programs based on
both expansions are available as supplementary material. Analytic expressions
are given for the scalar coefficient functions of the Fourier transform of the
electromagnetic part of the Argonne V18. A simple method for computing the
partial-wave projections of these interactions from the operator expressions is
also given.Comment: 61 pages. 26 figure
