Paleolithic cave art is an exceptional archive of early human symbolic behavior, but because obtaining reliable dates has been difficult, its chronology is still poorly understood after more than a century of study. We present uranium-series…

To represent 3-D space in detail, it is necessary to acquire 3-D shapes and textures simultaneously and efficiently through the use of precise trajectories of sensors. However, there is no reliable, quick, cheap, and handy method for acquiring…

Consider a large-scale wireless sensor network of n nodes, where a fraction k out of n generate data packets of global interest. Assuming that the individual nodes have limited storage and computational capabilities, we address the problem of how to…

In the ubiquitous (pervasive) computing era, it is expected that everybody will access information services anytime anywhere, and these services are expected to augment various human intelligent activities. Speech recognition technology can play an…

This report describes a method, presently called Ultra Bass, to evoke the illusion that a sound reproduction system has a high bass response, while the loudspeaker is less excited at low frequencies. It is based on a psychoacoustic e ect known as…
-
The recent advances made in MEMS and particularly in RF MEMS technology are enabling new architectures for the integration of RF transceivers with improved performance and smaller size. Several fundamental building blocks benefit from the…
-
Ultra Wideband Signals and Systems in Communication Engineering is a well-developed, introductory book on UWB technologies and applications, which is a strong resource for both beginners who seek an introduction to UWB principles and their…
-
Just-noticeable differences of physical parameters are often limited by the resolution of the peripheral sensory apparatus. Thus, two-point discrimination in vision is limited by the size of individual photoreceptors. Frequency selectivity is a…
-
Local storage is required in many sensor network applications, both for archival of detailed event information, as well as to overcome sensor platform memory constraints. While extensive measurement studies have been performed to highlight the…
-
Numerous efforts in balancing the trade-off between power, area and performance have been done in the medium performance, medium power region of the design spectrum. However, not much study has been done at the two extreme ends of the design…
-
This paper discusses ultra-low-power wireless sensor nodes intended for wearable biopotential monitoring. Specific attention is given to mixed-signal design approaches and their impact on the overall system power dissipation. Examples of trade-offs…
-
A flat optical device that generates optical vortices with a variety of topological charges is demonstrated. This device spatially modulates light beams over a distance much smaller than the wavelength in the direction of propagation by means of an…

This paper reports on the design and experimental verification of a new class of ultra-thin-film (250 nm) aluminum nitride (AlN) microelectromechanical system (MEMS) contour-mode resonators (CMRs) suitable for the fabrication of ultra sensitive…
-
In this paper, ultra-wideband (UWB) channel estimation based on the theory of compressive sensing (CS) is developed. The proposed approach relies on the fact that transmitting an ultra-short pulse through a multipath UWB channel leads to a received…
-
We review results on the recently developed dispersion-shifted, Chalcogenide waveguides demonstrating nonlinear signal processing on a compact monolithic platform with ultra-broadband capability and moderate launch powers of around 100 mW. Highlight…
-
Echolocating organisms represent their external environment using reflected auditory information from emitted vocalizations. This ability, long known in various non-human species, has also been documented in some blind humans as an aid to…
-
To overcome frame rate limitations in high-frequency ultrasound microimaging, new data acquisition techniques have been implemented for 2-D (B-scan) and color flow visualization. These techniques, referred to as retrospective B-scan imaging (RBI)…
