In this article a new neural-network architecture suitable for learning and generalization is discussed and developed. Although similar to the radial basis function (RBF) net, our computational model called the net with complex weights (CWN) has demonstrated a considerable gain in performance and efficiency in number of applications compared to RBF net. Its(More)
—Scanning tunneling microscopes (STM) and atomic force microscopes (AFM) are used to study biological materials. These methods, often capable of achieving atomic resolutions, reveal fascinating information regarding the inner workings of these materials. However, both STM and AFM require physical contact to the specimen. In the case of STM the specimen(More)
This paper presents a systematic test methodology targeting bus line interconnect defects using IDDT testing and Boundary Scan. Traditional test is unable to detect all possible defects, especially timing-related faults. Open and short defects on interconnects between embedded modules can be detected by IDDT testing. Boundary Scan can provide accessibility(More)
This paper presents the design of a bio-compatible, im-plantable neural recording device for Aplysia californica, a common sea slug. Low-voltage extracellular neural signals (<100 µV) are recorded using a high-performance, low-power, low-noise preamplifier that is integrated with programmable data acquisition and control, and FSK te-lemetry that provides(More)
A GaAs-based transistor, analogous to commercial silicon devices, has been fabricated with vapor-deposited cubic GaS as the insulator material. The n-channel, depletion mode, GaAs field-effect transistor shows, in addition to classical transistor characteristics, a channel mobility of 4665.6 square centimeters per volt per second, an interfacial trap(More)
Mechanical properties of self-welded ͓111͔ single-crystal silicon nanowire bridges grown between two silicon posts using metal-catalyzed chemical vapor deposition were determined using both dynamic and static measurements. The static tests were carried out using atomic force microscopy ͑AFM͒ to measure the nanowires' Young's modulus and the strength of the(More)
A new human-machine interface is introduced for "hands-free" tele-operation of mobile robots. This interface consists of tracking tongue movement by monitoring changes in airflow that occur in the ear canal. Tongue movements within the human oral cavity create unique, subtle pressure signals in the ear that can be processed to produce commands signals in(More)
In recent years, several alternative devices have been proposed to deal with inherent limitation of conventional CMOS devices in terms of scalability at nanometer scale geometry. The fabrication and integration cost of these devices, however, have been prohibitive and/or the devices do not allow smooth transition from the conventional design paradigm. To(More)

Idle power consumption is becoming an important parameter in portable embedded system design where excessive quiescent power dissipation can lead to excessive heat generation and reliability issues in nanometer-scale CMOS. To address some of these limitations, we have implemented a novel nano-electro-mechanical (NEM) switch with virtually zero leakage(More)
