The classical theory of radar resolution is based on narrowband sinusoidal waveforms and cannot directly be applied to ultrawideband (UWB) impulse radar. The concept of a generalized ambiguity function, which is a two-dimensional autocorrelation function in the range-Doppler domain, was first introduced by Harmuth in 1981 as a convenient design tool for the performance analysis of carrier-free ...

this study aims to design some dual-target anticancer candidates, capable to act as an alkylating agent as well as a thymidylate synthase (ts) inhibitor. the designed scaffold is a combination of nucleobase, amino acid and aziridine structures. the candidates are docked into ts and three dna double strand structures and evaluated based on their binding interaction energies and ligand efficienci...

This article presents the design of 1-bit metasurfaces for radar cross section (RCS) reduction over wide frequency band from 60 GHz to 120 GHz. The proposed can be designed without need any complicated optimization algorithms such as genetic (GA) or particle swarm (PSO), time-consuming simulations achieve optimized phase distribution map. maps required more than 10-dB RCS were generated using t...

In a variety of applications (including automatic target recognition) image classification algorithms operate on compressed image data. This paper explores the design of optimal transform coders and scalar quantizers using Chernoff bounds on probability of misclassification as the measure of classification accuracy. This design improves classification performance but the mean square error (as w...

The EMvibe is an augmented vibraphone that allows for continuous control over the amplitude and spectrum of individual notes. The system uses electromagnetic actuators to induce vibrations in the vibraphone’s aluminum tone bars. The tone bars and the electromagnetic actuators are coupled via neodymium magnets affixed to each bar. The acoustic properties of the vibraphone allowed us to develop a...

Error control codes have become a vital part of modern digital wireless systems, enabling reliable transmission to be achieved over noisy and fading channels. Over the past decade, turbo codes have been widely considered to be the most powerful error control code of practical importance. In the same time-scale, mixed voice/data networks have advanced further and the concept of global wireless n...
