This Paper deals with the problem of speech enhancement when a
corrupted speech signal with an additive colored noise is the only
information available for processing. Kalman filtering is known as
an effective speech enhancement technique, in which speech signal
is usually modeled as autoregressive (AR) process and represented
in the state-space domain.

This Paper addresses the issues relating to the
enforcement of robust stability when implementing the Adaptive
Inverse Control (AIC) scheme. In this scheme, an adaptive
FIR filter is added to a closed-loop system in order to
reduce the output error caused by external disturbances,
enhancing the performance achieved by linear time-invariant
controllers alone.
In this Paper, we describe the development of a mobile butterfly-watching learning (BWL)
system to realize outdoor independent learning for mobile learners. The mobile butterfly-watching
learning system was designed in a wireless mobile ad-hoc learning environment. This is first result
to provide a cognitive tool with supporting the independent learning by applying PDA with
wireless communication technology to extend learning outside of the classroom. Independent
learning consists of self-selection, self-determination, self-modification, and self-checking.
This Paper introduces a software visualization system that: creates animations of programs without the programmer writing any animation code and provides a window interface that automatically displays program information, explicitly showing the scope and context of its data, and allowing considerable control over animation displays.
This Paper describes some of the author s experiences from a C++ implementation of a concordance program for texts in Old West Norse and Runic Swedish.
This Paper presents several low-latency mixed-timing
FIFO (first-in–first-out) interfaces designs that interface systems
on a chip working at different speeds. The connected systems
can be either synchronous or asynchronous. The designs are then
adapted to work between systems with very long interconnect
delays, by migrating a single-clock solution by Carloni et al.
(1999, 2000, and 2001) (for “latency-insensitive” protocols) to
mixed-timing domains. The new designs can be made arbitrarily
robust with regard to metastability and interface operating speeds.
Initial simulations for both latency and throughput are promising.
