A small (7 x 5.75 x 11.5”) 45 MHz spectrometer with good resolution (< 1.8 Hz) and mid-to-low-range sensitivity that weighs 4.76 kg (10.5 lbs) and can acquire a 1D 1H or 19F spectra. PicoSpin was acquired by Thermo Fisher Scientific in December 2012, and subsequently renamed the product Thermo Scientific picoSpin 45. [ 23 ]
The latest version of Smaart 8 runs under Windows 7 or newer, and Mac OSX 10.7 or newer, including 32- and 64-bit versions. A computer having a dual-core processor with a clock rate of at least 2 GHz is recommended. [5] Smaart can be set to sample rates of 44.1 kHz, 48 kHz or 96 kHz, and to bit depths of 16 or 24.
With the development of thin film technologies it was possible to keep the Q factor high enough, leave out the crystal and increase resonance frequency. Ladder type bandpass filter based on FBAR resonators. The difference of resonance frequency of resonators 1 and 2 determine the frequency range of frequencies to be passed.
CONN includes a user-friendly GUI to manage all aspects of functional connectivity analyses, [1] including preprocessing of functional and anatomical volumes, [2] elimination of subject-movement and physiological noise, [3] outlier scrubbing, [4] estimation of multiple connectivity and network measures, and population-level hypothesis testing.
Resonant ultrasound spectroscopy (RUS) is a laboratory technique used in geology and material science to measure fundamental material properties involving elasticity.This technique relies on the fact that solid objects have natural frequencies at which they vibrate when mechanically excited.
Taking for example the H 2 O molecules in liquid phase without the contamination of oxygen-17, the value of K is 1.02×10 10 s −2 and the correlation time is on the order of picoseconds = s, while hydrogen nuclei 1 H at 1.5 tesla precess at a Larmor frequency of approximately 64 MHz (Simplified. BPP theory uses angular frequency indeed).
Resonance frequency analysis was first suggested as an alternative method of analyzing peri-implant bone in a scientific paper by Meredith N et al in 1996. [4] As stated in the paper’s abstract, in measuring implant stability and osseointegration, “radiographs are of value, but a standardised technique is necessary to ensure repeatability.” [4] The new technique tested involved ...
Dielectric relaxation as a whole is the result of the movement of dipoles (dipole relaxation) and electric charges (ionic relaxation) due to an applied alternating field, and is usually observed in the frequency range 10 2-10 10 Hz.
