With the advancement of wireless and electronic technologies, wireless networks consist of tiny sensor devices hold the promise of revolutionizing sensing in a wide range of application domains because of their flexibility, low costs and ease of deployment. In this paper, the employment of ad-hoc wireless sensor networks to perform signals classification is proposed. For such application, the use...
Capacitive RF MEMS switches present several drawbacks such as high actuation voltages, slow switching times and time-varying performances, due to the deterioration of both their mechanical and electrical properties. Such characteristics justify the interest of the scientific community on the development of accurate measurement techniques to monitor the dynamic behavior of capacitive MEMS switches...
The paper presents the design of a very-high speed Track-and-Hold amplifier (THA) aimed at low power consumption. Tha THA is based on a half diode bridge driving a switched emitter follower. It features 10-b resolution at 1-GS/s with less than 25-mW of power consumption.
We model here a distributed implementation of cross-stopping, a combination of cross-validation and early-stopping techniques, for the selection of the optimal architecture of feed-forward networks. Due to the very large computational demand of the method, we use the RAIN system (Redundant Array of Inexpensive workstations for Neurocomputing) as a target platform for the experiments and show that...
A novel comparator, featuring 8bit resolution, 160Ms/s at 3.3V supply, was designed and tested. By the use of BiCMOS technology, it, overcomes the limits of the conventional bipolar circuits, in terms of reduced power consumption and supply voltage. Test results, obtained with both classical and statistical techniques, are reported.
Current knowledge on mineral coal deashing by selective oil agglomeration was applied to deashing of charcoal. The effects of various operating variables were studied.
The design of low-cost distributed real-time classifiers whose inputs are the physical data from the environment is an issue of major interest in the emerging technology of so-called smart sensors. When a classifier has to be implemented on low-power and low-cost platforms, a tradeoff between classification accuracy and implementation complexity must be pursued. Here, a multiobjective optimization...
