The LEDA RFQ is a 350-MHz continuous-wave (CW) radio-frequency quadrupole linac. LEDA is the low energy demonstration accelerator, a full power front-end prototype for the accelerator production of tritium (APT) linac. This machine has accelerated a 100-mA CW proton beam from 75 keV to 6.7 MeV. The 8-m-long RFQ accepts a dc, 75–keV, ~110-mA H beam from the LEDA injector, bunches the beam, and a...

We present a novel approach to automatic estimation of tempo over time. This method aims at detecting tempo at the tactus level for percussive and nonpercussive audio. The front-end of our system is based on a proposed reassigned spectral energy flux for the detection of musical events. The dominant periodicities of this flux are estimated by a proposed combination of discrete Fourier transform...

Satellite observations suggest that the thermal radiation emitted by Earth to space increased by more than 5 watts per square meter, while reflected sunlight decreased by less than 2 watts per square meter, in the tropics over the period 1985-2000, with most of the increase occurring after 1990. By analyzing temporal changes in the frequency of occurrence of emitted thermal and reflected solar ...

Measurement of complex impedance of biological systems is gaining wide popularity in determining the pathological and physiological status of tissues in research areas such as; body fat content, blood freshness, tissue ischemia, skin hydration, and etc. In this paper, we designed a fourprobe, multi-frequency impedance meter for quick assessment of the viability of erythrocyte suspensions under ...

Smart Grid solutions are being rolled out at large scale these days. While security concerns are addressed on various levels and sophisticated technical measures applied, privacy issues are still not fully understood yet. The generation of high-frequency meter readings exposes customers to new threats. Various politic initiatives thus aim towards a strong regulatory framework to enable an appro...

Many connectionist approaches to musical expectancy and music composition let the question of “What next?” overshadow the equally important question of “When next?”. One cannot escape the latter question, one of temporal structure, when considering the perception of musical meter. We view the perception of metrical structure as a dynamic process where the temporal organization of external music...

A distribution of the meter-wave luminous objects, which are bright at frequency 74 MHz (a wavelength of 4 m) but not detectable at 1.4 GHz (21 cm) in the VLA surveys, shows a notable concentration in a scale of a few degrees toward Monoceros [(l, b)=(225, 4)]. We argue that it is a part of giant radio relics associated with a nearby cluster of galaxies with cz ∼ 2400 km s centered on the spira...

A dielectric measurement for the aqueous solutions at lower frequencies (20Hz to 2MHz) has been carried out in frequency domain using Agilient Precision LCR meter (E4980A). The dielectric permittivity spectra of over entire concentrations with aqueous solutions are measured at 25 ̊C. From observed spectra, static dielectric constants (ε0) have been determined. Dielectric Spectroscopy is especial...

One kind of prosodic structure that apparently underlies both music and some examples of speech production is meter. Yet detailed measurements of the timing of both music and speech show that the nested periodicities that deene metrical structure can be quite noisy in time. What kind of system could produce or perceive such variable metrical timing patterns? And what would it take to be able to...
