Stochastic Gravitational Wave Measurements with Bar Detectors: Dependence of Response on Detector Orientation

, 2005
The response of a cross-correlation measurement to an isotropic stochastic gravitational-wave background depends on the observing geometry via the overlap reduction function.

Stochastic Discontinuous Galerkin Methods (SDGM) based on fluctuation-dissipation balance

Results in Applied Mathematics, 2019
We introduce a general framework for approximating parabolic Stochastic Partial Differential Equations (SPDEs) based on fluctuation-dissipation balance. Using this approach we formulate Stochastic Discontinuous Galerkin Methods (SDGM).

Multiscaling in passive scalar advection as stochastic shape dynamics

, 1997
The Kraichnan rapid advection model is recast as the stochastic dynamics of tracer trajectories. This framework replaces the random fields with a small set of stochastic ordinary differential equations.

System-Level Modeling and Optimization of the Energy Efficiency in Cellular Networks—A Stochastic Geometry Framework [PDF]

IEEE Transactions on Wireless Communications, 2018
In this paper, we analyze and optimize the energy efficiency of downlink cellular networks. With the aid of tools from stochastic geometry, we introduce a new closed-form analytical expression of the potential spectral efficiency (bit/sec/m2).

Semigroups of finite-dimensional random projections [PDF]

, 2010
In this paper we present a complete description of a stochastic semigroup of finite-dimensional projections in Hilbert space. The geometry of such semigroups is characterized by the asymptotic behavior of the widths of compact subsets with respect to the
