Abstract

A far-field optical microscope capable of reaching nanometer-scale resolution using the in-plane image magnification by surface plasmon polaritons is presented. The microscope utilizes a microscopy technique based on the optical properties of a metal-dielectric interface that may, in principle, provide extremely large values of the effective refractive index n.sub.eff up to 10.sup.2-10.sup.3 as seen by the surface plasmons. Thus, the theoretical diffraction limit on resolution becomes .lamda./2n.sub.eff, and falls into the nanometer-scale range.

Abstract

In a communication network, the responsiveness of the transmission rate of data packets to packet drops is quantified for an aggregate of flows as opposed to on a per-flow basis. In an Aggregate Perturbation Method (APM), a small number of data packets is intentionally dropped from the aggregate at a switching node and a response thereto is measured. Traffic not conforming to the predetermined transmission control protocol may be discovered as a decrement in the reduction in traffic rate compared to that anticipated based on the rate of dropped packets.

Abstract

A denoising mechanism uses chosen signal classes and selected analysis dictionaries. The chosen signal class includes a collection of signals. The analysis dictionaries describe signals. The embedding threshold value is initially determined for a training set of signals in the chosen signal class. The update signal is initialized with a signal corrupted by noise.

Abstract

A probabilistic framework for acoustic-phonetic automatic speech recognition organizes a set of phonetic features into a hierarchy consisting of a broad manner feature sub-hierarchy and a fine phonetic feature sub-hierarchy. Each phonetic feature of said hierarchy corresponds to a set of acoustic correlates and each broad manner feature of said broad manner feature sub-hierarchy is further associated with a corresponding set of acoustic landmarks. A pattern recognizer is trained from a knowledge base of phonetic features and corresponding acoustic correlates.
