Hypermodular parallel printing systems
We describe a system consisting of hypermodules (bidirectional nip assemblies and sheet director assemblies) each of which has its own computation, sensing, actuation, and communication capabilities.
-
Server-side detection of malware infection
We review the intertwined problems of malware and online fraud, and argue that the fact that service providers often are financially responsible for fraud causes a relative lack of incentives…

Low-cost interrogation unit for wavelength-encoded optical sensors
We have developed a low-cost, compact, fast-response wavelength detector that is well suited for the read-out of wavelength-encoded sensors.

The ‘out-of-avatar experience’: object-focused collaboration in Second Life
In this paper we present the results of an investigation into collaborative building in Second Life.

Novel approach to make low cost, high density PZT phased array and its application in structural health monitoring
In this paper we present a cost effective method to fabricate flexible, high density piezoelectric tape, and explore its potential application as a new type of Lamb wave phased array…

Which way am I facing: inferring horizontal device orientation from an accelerometer signal
We present a method to infer the orientation of mobile device carried in a pocket from the acceleration signal acquired when the user is walking.

An Unfinished Canvas: Arts Education in California
SRI examined student access to arts education in California schools and conducted follow-up studies examining factors influencing K–12 arts education.

Ultra-Low-Power Electronics for Non-Invasive Medical Monitoring
We focus on the monitoring of the heart and describe a micropower electrocardiograph, an ultra-low-power pulse oximeter, an ultra-low-power phonocardiograph, an integrated-circuit switched-capacitor model of the heart, and a low-power…

First Observations of Large-Scale Wave Structure and Equatorial Spread F Using Certo Radio Beaconon the C/NOFS Satellite
First observations of large-scale wave structure and the subsequent development of equatorial spread F, using total electron content derived from the ground based reception of beacon signals from the CERTO…

The Wake-Promoting Effects of Hypocretin-1 are Attenuated in Old Rats
We sought to determine whether the wake-promoting effect of hypocretin changes with age in Wistar rats, a strain in which age-related changes in both sleep and hypocretin signaling have been…

Building a Highly Accurate Mandarin Speech Recognizer with Language-Independent Technologies and Language-Dependent Modules
We describe a system for highly accurate large-vocabulary Mandarin speech recognition. The prevailing hidden Markov model based technologies are essentially language independent and constitute the backbone of our system.
