  1. Vector quantization applied to speech coding in the wireless environment

    … Digital Cellular (NADC) 8kbps Vector-Sum Excited Linear Prediction (VSELP) speech coder and is currently capable of simulating the complete IS-54 source and channel coding scheme. The system is tested using Multi-Stage Vector Quantization and Finite-State Vector Quantization (FSVQ) applied to the …

  2. Parameter Estimation of Structural Systems Possessing One or Two Nonlinear Normal Modes

    … that can be described in terms of one or two nonlinear normal modes. We model the dynamics of these modes by second-order ordinary-differential equations based on the principles of mechanics, past experience, and engineering judgment. We perform a number of separate experiments on a two-mass …

  3. Interaction between ferric hydroxides and dissolved sulfide in anoxic aquifers: Pathway and kinetics of iron and sulfur products formation

    … lead to the potential formation of non-crystalline iron-polysulfide species and a supersaturation with respect to pyrite, thereby inducing rapid pyrite formation in the HR experiment. The rapid pyrite formation has been proposed as a ‘novel’ polysulfide pathway because ferrous iron and …
