TL;DR: The proposed planning model is a two-stage stochastic linear program (SLP) with recourse, a sampling based algorithm called Stochastic decomposition (SD) for very large-scale SLPs, such as the ones solved in this application.
Abstract: We study a planning problem associated with networks for private line services. In these networks, demands are known to exhibit considerable variability, and as such, they should be treated as random variables. The proposed planning model is a two-stage stochastic linear program (SLP) with recourse. Due to the enormous size of the deterministic equivalent, we choose a sampling based algorithm calledstochastic decomposition (SD). For very large-scale SLPs, such as the ones solved in this application, SD provides an effective methodology. The model presented in this paper is validated by using a detailed simulation of the network. We report results with a network that has 86 demand pairs, 89 links and 706 potential routes.

TL;DR: In this paper, the authors calculate the total electromagnetic field from a surface of finitely sized metal or dielectric particles by superposition: Scalar potentials characterizing a single particle are convoluted with a distribution function describing the particle positions.
Abstract: Amplified electromagnetic fields generated by a surface of finitely sized metal or dielectric particles are calculated. Regular arrays of particles produced by lithographic techniques and stochastic particle distributions that occur, e.g., in island films, are discussed. Retarded dipolar interactions between the particles are explicitly taken into account. Particles of finite size are considered for which dynamic depolarization and radiation damping effects are important. Limits of validity of the present approach are indicated. The total electromagnetic field from the surface is calculated by superposition: Scalar potentials characterizing a single particle are convoluted with a distribution function describing the particle positions. The surface Hertz vector is obtained from the single-particle Hertz vector by convolution with a two-dimensional Shah function representing the array or with the autocorrelation function of the stochastic surface. A plane-wave description of the dipolar fields is used, whereby the convolution is transformed into a simple multiplication in Fourier space. Cylindrical, general spheroidal, and spherical shapes are considered for the individual particle. Particle dipole moments are obtained by a self-consistent procedure. Dipolar interactions result in shifts and broadening of the particle plasmon resonances, which are responsible for the local intensity enhancement. A set of universal curves is given from which shift and broadening can be calculated for particles of all sizes and shapes. Extrema in the dipolar interactions arise when grating orders change from radiative to evanescent character. The strong variation of the Raman enhancement with angle and wavelength in the vicinity of these extrema is clearly predicted from the Hertz-vector calculation. The formalism described permits one to calculate electromagnetic properties of the surface and enhancement factors for any electromagnetic process occurring at or near the surface. As examples, the calculation of reflectivities for s-and p-polarized excitation and surface-enhanced Raman-scattering cross sections are discussed.

29 Apr 2005TL;DR: In this article, a wireless communications device determines a transmission power level maximum based on the received signal and then transmits a signal to the access point at a transmission level at or below the transmission level maximum, disables the transmission when the signal strength falls below a predetermined threshold.
Abstract: The present invention provides for a method and apparatus for reducing interference associated with wireless communication in an area having sensitive electronic equipment. A wireless communications device receives, from an access point, a signal having a signal strength above a predetermined threshold. The wireless communications device determines a transmission power level maximum based on the received signal and then transmits a signal to the access point at a transmission power level at or below the transmission power level maximum. The wireless communications device disables the transmission when the signal strength falls below the predetermined threshold.

16 Dec 1997TL;DR: In this paper, a wide area information system includes a client and at least one server on which audio data is stored and is selectively transferred to the client from the server by at least occasionally establishing a transfer connection between the server and the client.
Abstract: A wide area information system includes a client and at least one server on which audio data is stored. Audio data is selectively transferred to the client from the server by at least occasionally establishing a transfer connection between the server and the client. The transfer of audio data is controlled by user-selected commands and inputs that are entered via an input interface provided on the client. These commands and inputs are also transferred to the server via the at least occasionally established transfer connection between the client and the server. The audio data on the server is organized in page units that are cross-linked by way of hyperaudio links. The page units are characteristically searchable with the use of cyclically repeating directory pages of audible directory information. A data protocol is defined for enabling such an audio-based system.
