講演タイトル
Signal Processing for Health Monitoring of Aerospace Structures
(by V. John Mathews)
(4) Abstract(講演概要)
"Signal Processing for Structural Health Monitoring” (by V. John
Mathews) Modern airplanes contain substantial amounts of load-
bearing composite parts. Composite materials used in aerospace
applications are typically light and strong, but are susceptible
to internal damages with little or no external evidence.
Consequently it is desirable to develop and implement health
monitoring systems on composite aerospace structures that
continuously monitor the structure for events that may result in
damage, and when such events occur, detect and assess the extent
of any damage that may have resulted. Such systems can increase
the reliability of aircrafts by ensuring their flightworthiness
and detecting potential problems as they arise. They will
facilitate lean designs that meet tolerance levels specified by
barely detectable damages. By avoiding excess conservatism, the
system will reduce manufacturing and maintenance costs. Another
attractive aspect of these systems is their ability to monitor
parts and locations of aircrafts that are not easily accessible
and require disassembling for inspection. In this talk, we will
review structural health monitoring techniques that utilize an
array of ultrasound transducers on the structure. We will discuss
the basic approaches for detecting damage and determining the
extent of damage in the structure through a combination of passive
and active approaches, and practical challenges in the
implementation of such systems. Part of this talk is based on work
done for the Boeing Company.
"Signal Processing for Diagnostic Medicine" (by V. John Mathews)
Analysis of commonly measured physiological signals can provide
many clues about a person’s health. An example is heart rate
variability. Heart rate variability and other measures of
complexity of the heart rate behavior over time have been used in
health assessment of adults, children and fetuses. The first part
of this talk will provide two examples of how heart rate
variability and related properties of the circulation system may
be used for early detection of pregnancy-related diseases such as
preeclampsia, and to monitor the status of adult sepsis patients.
The second part of the talk will discuss how we can apply signal
processing techniques to build tools for reliably and non-
invasively monitoring the cardiovascular state of fetuses using
ultrasound techniques. In this part of the talk, we will answer
questions such as: (1) How can we accurately measure heart rate
variability in fetuses? (2) How do we noninvasively measure aortic
blood pressure in fetuses? (3) Is it possible to measure and track
parameters of the fetal circulation system such as the diameter of
fetal arteries and properties such as pulse wave velocity and
shear stress on aortic walls?
"Restoration of Motor Skills in Patients with Disorders of the
Central Nervous System" (by V John Mathews) Recent technological
innovations such as functional neural stimulation (FNS) offer
considerable benefits to paralyzed individuals. FNS can produce
movement in paralyzed muscles by the application of electrical
stimuli to the nerves innervating the muscles. The first part of
this talk will describe how smooth muscle movements can be evoked
using Utah slanted electrode arrays (USEAs) inserted into the
motor nerves of the peripheral nervous system. The standard 4 x 4
mm USEAs contain 100 electrodes of varying lengths. Implantation
of a USEA in a peripheral nerve allows highly selective electrical
access to individual and small groups of axons. We will review
approaches for designing asynchronously interleaved stimulation
signals applied via individual electrodes in the arrays to evoke
smooth, fatigue-resistant force that closely resembles normal
motor function. The second part of this talk will describe efforts
to decode cortical surface potentials, recorded with dense grids
of microelectrodes. Decoding human intent from neural signals is a
critical component of brain-computer interfaces. This information
can then be used to control the muscles in tasks involving
restoration of motor skills or to control a robot that performs
desired tasks. We will discuss recent work on decoding neural data
collected from patients implanted with microelectrode arrays. The
talk will conclude with a discussion of some of the current
research challenges in this area.
"Multichannel Echo Cancellation: Discovery of the Uniqueness
Problem and Search for Solutions" (by Akihiko Sugiyama) This talk
presents how the uniqueness problem has been discovered along with
its solutions. The uniqueness problem has been a popular research
topic in echo cancellation since its discovery in 1991. Starting
from a linearly combined stereo echo cancellation model, the
uniqueness problem is explained by illustrations. These
illustrations naturally lead to one of the most promising
solutions based on a sliding technique that may not be easily
reached otherwise. Other solutions proposed in the two and a half
decades are also briefly explained.

serves on the editorial board of the IEEE Signal Processing
Magazine. He has served on the organization committees of several
international technical conferences including as General Chairman
of IEEE International Conference on Acoustics, Speech and Signal

Information and Media Processing Labs., has been engaged in a wide
variety of research projects in signal processing such as audio
coding and interference/noise control. His team developed the
