Despite numerous bounds and partial results, the feedback capacity of the stationary nonwhite Gaussian additive noise channel has been open, even for the simplest cases such as the first-order autoregressive Gaussian channel studied by Butman, Tiernan and Schalkwijk, Wolfowitz, Ozarow, and more recently, Yang, Kavccaronicacute, and Tatikonda. Here we(More)
The dynamics of piston's secondary motion (lateral and rotational motion) across the clearance between piston and cylinder inner wall of reciprocating machines are analyzed. This paper presents an analytical model, which can predict the impact forces and vibratory response of engine block surface induced by the piston slap of an internal combustion engine.(More)
Single-stage switching transfer functions of force-commutated frequency changes are generalized for an arbitrary number of input/output phases. Then, practical modulation methods and their mathematical analysis for generalized switching transfer functions are presented. The proposed modulation techniques are mathematically justified and were implemented(More)
The three-stage operation of force-commutated, direct-type frequency changers, which provides the capabilities of output magnitude control, harmonic control, and input power factor control, especially when microprocessor-based control is used, is described. The harmonic analysis of a three-phase input, three-phase output system and the implementation of the(More)

—Short-wavelength radar networks are expected to complement current long-range weather radar systems. Accordingly, we proposed a configuration for such a network constituting pulse compression radars in order to use frequency resources efficiently and obtain multi-static information. We developed high resolution Ka-band pulse compression weather radar(More)
