In this paper we show that the use of a resonant cavity filled with a lossy dielectric we can overcome the negative energy density requirement in Alcubierre's warp field equations. By using an imaginary part equal to or greater than the real part in the shaping function we generate a positive, non-exotic energy density requirement to generate and s...
Article
In this paper, we investigate broadband supercontinuum generation in photonic crystal fibers using cosh-Gaussian optical pulses, which provide flatter spectrum than standard Gaussian pulses. This fact can be crucial for telecommunication systems applications. The intensive numerical study of three main telecommunication windows pointed out the most...

An infiltration characteristic model was developed by using the modified Kostiakov method for the Agricultural Engineering demonstration field of Bangladesh Agricultural Research Institute (BARI). The constant values a, α, and b of the equation for accumulated infiltration y = atα + b were 9.12, 0.683, and 0.145, respectively. The average value of...

Thermal energy in the environment is a potential and possible source of electrical energy for low-power electronics. The ambient temperature variation can be converted into electrical current or voltage via the pyroelectric effect using smart materials. The possibility of the utilizing pyroelectric materials in energy harvesting from roads warrants...

Piezoelectric materials generate electricity when they are subjected to dynamic strain. Much energy harvesting research has been performed with PZT type ceramics based piezoelectric transducers because of their relatively large electrical response to mechanical vibrations. However, notwithstanding their relatively low piezoelectric coefficients, pi...

Numerous industrial operations involve fluid-particle systems, in which both phases display very complex behaviour. Some examples include fluidisation technology in catalytic reactors, pneumatic transportation of grain or powder materials, carbon nanotube alignment in the nano-devices and circuit integration and so on. In this paper, a macro partic...

Images are about pictures. Percepts are about information. People need images. Machines do not. This paper suggests that it may be possible for machines to perceive things, not just register images in real time. This goal inspired our search for methods that might work in real time to perceive their world. In our brains, the image is processed sepa...

In this paper we will discuss the utilization of a set of waveforms derived from chaotic dynamical systems for compression and feature recognition in digital images. We will also describe the design and testing of an embedded systems implementation of the algorithm. We will show that a limited set of combined chaotic oscillations are sufficient to...

The paper presents occurrence of rainfall using principles of fuzzy set theory and principles of reliability analysis. Both the abstract and the rest of the paper are discussed from these two points of view. First, a fuzzy inference model for predicting rainfall using scan data from the USDA Soil Climate Analysis Network Station at Alabama Agricult...
Article
Solar images taken at different wavelengths enable scientists to visualize and analyze the suns activities. The Solar Dynamics Observatory (SDO) provides high-resolution images of the sun, with cadence in seconds, taken at varying wavelengths, resulting in finely detailed, almost continuous data for researcher's examination. We propose an approach...
Conference Paper
This paper describes the formulation and analysis of a new digital multiplexing technique. Mutually orthogonal chaotic (MOC) multiplexing has its foundation in nonlinear dynamical systems and chaos theory. We outline the conceptualization and analysis of the algorithm. We show simulation results for the implementation and show that there is superio...
Conference Paper
We have developed a method of detecting extremely weak signals using fundamental principles of chaotic dynamics. We calculate the time-dependent coupling of the disturbance signal to the stable and unstable manifolds of the system and derive a relationship between the disturbance and the error on the Poincare surface of section, thus relating the d...
Article
It has been shown both theoretically and experimentally that it is possible to control the symbolic dynamics of a chaotic system using small perturbations. We show a method of very rapidly targeting a region of width e near a desired state point on a one-dimensional map using control of symbolic dynamics; this method demonstrates that controlling s...
Article
Chaotic behaviour has been observed in a microwave limiter circuit that consists of a shunt p-i-n diode cascaded with a 0.68-dB/MHz rolloff bandpass filter. The chaos manifests itself as a broad-band power spectral density of the output signal. The chaos appears and disappears as the incident power to the limiter circuit is increased, suggesting bi...

Recently there has been a resurgence of interest in the vacuum valve. Manufacturing capabilities in the area of semiconductor microelectronic devices have paved the way for the emergence of vacuum microelectronic (VuE) technology. The possibility of these new devices becoming a robust, high-speed alternative to solid-state electronics has caught th...
Article
A compact, quasi-active delay-line limiter/filter (QUADLF) was designed to limit high-power, fast-rise-time pulses and prevent spike leakage, which is common to conventional limiting techniques. The QUADLF design incorporates both waveguide and microstrip technologies. Over the operating frequency range, from 0.8 to 1.2 GHz, experimental results sh...

In our development of a chaotic oscillator technology to produce high-quality communication signals, we have found a novel method for limiting the out-of-band spectral power from chaotic oscillators. This development is an important breakthrough that has allowed us to make a major step toward a commercially viable technology.

In this paper we discuss the formulation of, and show the results for, a new compression/decompression algorithm called DYNAMAC, that has its basis in nonlinear systems theory. We show that we are able to achieve significant compression of RGB image data while maintaining good image quality. We discuss the implementation of this algorithm in hardwa...

This paper describes the design and simulation results of a new concept in power amplification called Syncrodyne power amplification. Here we describe the design procedure for our Series-3 power amplifier for GSM waveforms. The foundation of this design has its basis in a subset of nonlinear behavior called chaotic dynamics. Since the groundbreakin...
