A new design of Ultra-Wide band (UWB) generator is described in this paper. The UWB impulse generator circuit is the most essential block in a mono-band UWB transmitter. The proposed ultra wide band impulse generator circuit utilizes the performances of the CMOS technology e®ectively, it is composed of a voltage controlled oscillator (VCO), and a rectangular pulse generator (RPG) and mixer. The...

Entrainment is the integration or harmonization of oscillators. All organisms pulsate with myriad electrical and mechanical rhythms. Many of these rhythms emanate from synchronized pulsating cells (eg, pacemaker cells, cortical neurons). The cranial rhythmic impulse is an oscillation recognized by many bodywork practitioners, but the functional origin of this impulse remains uncertain. We propo...

The present study hypothesized that unfulfilled basic needs for autonomy, competence and relatedness (SDT, Deci and Ryan, Psychol Inq 11:227 268, 2000) are associated with the impulse to eat and with binge eating. In addition, we assumed that individuals with a high achievement motive, who are characterized by high selfcontrol competences, have the same impulse to eat when confronted with unful...

A new boundary force is proposed to solve rigid body interaction in SPH (Smoothed Particle Hydrodynamics). The new boundary force is impulse-based rather than potential-based. The impulse is converted to a boundary force with a fundamental observation that the impulse is a momentum change which is a result of a force acting on an object during a time interval. Our new impulse-based boundary for...

Spectral properties and performance of multi-pulse impulse radio ultra-wideband systems with pulse-based polarity randomization are analyzed. Instead of a single type of pulse transmitted in each frame, multiple types of pulses are considered, which is shown to reduce the effects of multiple-access interference. First, the spectral properties of a multipulse impulse radio system is investigated...

In CG community, many kinds of physical-based (impulse-based) approaches such as Mirtich’s and Baraff’s ones have been proposed for showing dynamic animation. However, because they generate and calibrate only an impulsive force, i.e., an area of force distribution, the impulsive forces are not always precisely calibrated. Moreover, since they do not deal with any exact impulse (force distributi...

In this paper, experimental results on impulsive synchronization of two kinds of chaotic circuits; namely, Chua’s oscillator and a hyperchaotic circuit, are presented. To impulsively synchronize two Chua’s oscillators, synchronization impulses sampled from one state variable of the driving circuit are transmitted to the driven circuit. To impulsively synchronize two hyperchaotic circuits, synch...

Instead of pilot tones, the impulse sample is exploited for channel estimation in Impulse Postfix OFDM systems [1]. As the magnitude of impulse sample is increased, the accuracy of channel estimation can be enhanced, but it may significantly increase the PAPR of generated OFDM symbols. In this letter, based on the statistical analysis of the generated OFDM symbol, we propose a decision scheme f...

A new method is proposed to eliminate impulse noise with a random intensity distribution in digital images. The method is based on impulse noise detection by means of a self-organizing tree map (SOTM) and a class of noise-exclusive adaptive filters. The SOTM classifies the image pixels into clusters and locates the cluster centers that represent the mean intensities of the impulse noise. Based ...

In this paper a multi-statistics model of the impulse noise is presented. An impressive experimental noise data collection acquired from digital access loops provides the synthetic noise environment with the most convenient probability density functions. Internal and external impulse noise sources within communications copper lines are briefly surveyed. A wide-band noise measuring circuit is us...
