Frequency response of human skin in vivo to mechanical stimulation
… mechanical impedance, power absorption and duty factor (an estimate of the fraction of time that the stimulator is in contact with the skin). Results showed the mechanical impedance generally increasing in magnitude with frequency and higher in magnitude for tangential stimulation than for …

Differential Cross Sections for Compton Scattering Off the Proton at 185 MEV
… Accelerator Laboratory using the new high duty factor elec-tron beam. The scattered photons were observed with a high resolution, total absorption N ai scintillation detector. The resolution of the detector was sufficient to exclude Π° de-cay photons from the region of interest.

A coincident measurement of the three-body photodisintegration of helium-3
… of Illinois Nuclear Physics Laboratory 100% duty factor electron microtron. The energy and angle of the np pairs were used to reconstruct the energy of the photon, making this a kinematically complete experiment. The $\sp3$He($\gamma$,np)p data were normalized to measured $\sp2$H($\gamma$,np) …

INVESTIGATION OF STRATEGIES FOR IMPROVING THE PERFORMANCE OF SMART THERMOSTAT-DRIVEN FDD METHODS
… air responses to both AC operations and other factors like weather and building gains. As these other factors are typically unmeasurable by smart thermostats and yet prone to variability, they pose potential disturbances which can affect AC operation. This makes estimating the impact of these …

The neutron electric form factor to Q² = 1.45 (GeV/c)²
The nucleon elastic electromagnetic form factors are fundamental quantities needed for an understanding of nucleon and nuclear electromagnetic structure. The evolution of the Sachs electric and magnetic form factors with Q2, the square of the four-momentum transfer, is related to the distribution …

The effect of an abrupt change in functional surface properties on equine kinematics and neuromuscular activity
… for training and competition are influenced by factors such as weather and maintenance, which can lead to spatial variations in functional surface properties. The ability of the horse to adapt to such changes may have implications for injury prevention. The aim of the PhD was to quantify …

Measurement of the partial cross-sections sigmaTT, sigmaLT and sigmaT + epsilon-sigmaL of the p(e,e'pion+)n reaction at the Delta(1232) resonance
… Of Plane Spectrometer system (OOPS) using a high duty factor (>50%) 950 MeV unpolarized electron beam. The One Hundred Inch Proton Spectrometer (OHIPS) detected electrons, and three OOPS modules provided out of plane hadron detection in two sequential sets of simultaneous measurements. The sigmaLT …

The ²H(<i>e, e'p</i>)<i>n</i> Reaction at High Four-Momentum Transfer
… <p>The unique combination of energy, current, duty factor, and control of systematics for Hall A at Jefferson Lab made Jefferson Lab the only facility in the world where these systematic studies of the deuteron can be undertaken. This is especially true when we want to understand the short …

A study of the photon decay modes of the giant dipole resonance in even-A neodymium isotopes
… Model and the Interacting Boson Model. A 100% duty-factor, 24 MeV electron beam provided the tagged, bremsstrahlung photons. The scattered photons were detected in two large NaI(TI) crystals, whose energy resolution was typically f'V 3%. This allowed the inelastic scattering cross sections to …

Measurement of the electric form factor of the neutron at low momentum transfers using a vector polarized deuterium gas target at BLAST
Elastic form factors are fundamental quantities that characterize the electromagnetic structure of the nucleon. High precision measurements of these quantities are essential in understanding the structure of hadronic matter. Although the proton elastic form factors are well known, knowledge of the …

Improved seismic isolation for the Laser Interferometer Gravitational Wave Observatory with hydraulic external pre-isolator system
… noisier than that of LHO, from 0.1 to 3Hz, by a factor of 2.4 to 9.0. To cope with noisier ground conditions at LLO, an additional stage of seismic isolation system external to the LLO vacuum tanks was developed. The system is called the Hydraulic External Pre-Isolator (HEPI), which uses position …
