Pervasive networks of wireless sensor and communication nodes have the potential to significantly impact society and create large market opportunities. For such networks to achieve their full potential, however, we must develop practical solutions for self-powering these autonomous electronic devices. We've modeled, designed, and built small(More)
“CyberCutTM” is a testbed for an Internet-based CAD/CAM system. It was specifically designed to be a networked, automated system, with a seamless communication flow from a client-side designer to a server-side machining service. The creation of CyberCut required several new software modules. These include: a) a Web-based design tool in which(More)
This paper presents an evolution-based approach for solving multiple molecular sequence alignment. The approach is based on the island parallel genetic algorithm that relies on the fitness distribution over the population of alignments. The algorithm searches for an alignment among the independent isolated evolving populations by optimizing weighted sum of(More)
Brain-computer interfaces (BCI) are recent developments in alternative technologies of user interaction. The purpose of this paper is to explore the potential of BCIs as user interfaces for CAD systems. The paper describes experiments and algorithms that use the BCI to distinguish between primitive shapes that are imagined by a user. Users wear an(More)
This paper discusses the use of a brain computer interface (BCI) to obtain emotional feedback from a human in response to the motion of humanoid robots in collaborative environments. The purpose of this study is to detect the human satisfaction level and use it as a feedback for correcting and improving the behavior of the robot to maximize human(More)
We present a CDMA wireless infrastructure chip that handles digital baseband receive functions for up to 64 voice channels, representing over 150 GOPS of computation, and dissipating 32mW/channel. Vector datapaths and two embedded ARM cores are employed for flexibility and high channel density. The chip is fabricated in a 130 nm 7 layer metal process and(More)
The paper discusses key issues in the measurement and control of risks in Islamic Financial Services Institutions, particularly the implications of profit sharing investment accounts (PSIA) for risk measurement, risk management, capital adequacy and supervision. Cross country data on a sample of banks reveal a considerable smoothing of returns paid to PSIA,(More)
