An absolute measurement of the photodisintegration of deuterium
… division technique in the wire chamber. The ~~ measurements in the wire chamber and the scintillators allowed the separation of protons from electrons. Timing coincidences in the scintillators with the photon tagging counters allowed the randomly-timed background to be subtracted. The …

An absolute measurement of the photodisintegration of Helium-4
A measurement of the differential cross section has been performed for the photodisintegration of ⁴He into a proton plus a triton. This reaction is highly sensitive to the electromagnetic currents in the nucleus which arise from the exchange of mesons between nucleons. The study of light nuclei …

An absolute measurement of the photodisintegration differential cross section of the deuteron
We have measured the absolute $\rm\sp2H(\gamma,p)n$ angular distribution using the Illinois LASA detector at the Saskatchewan Accelerator Laboratory's tagged photon facility. Using 40 to 90 MeV photons, we aimed to measure the differential cross section with a statistical precision of typically 5% …

An absolute measurement of the photodisintegration differential cross section of the deutron
We have measured the absolute 2H( 1 ,p )n angular distribution using the Illinois LASA detector at the Saskatchewan Accelerator Laboratory's tagged photon facility. Using 40 to 90 MeV photons, we aimed to measure the differential cross section with a statistical precision of typically 5% in angular …

Kinematic Calibration of Serial Manipulators Using Relative Measurements
… kinematic calibration method using relative measurements is developed and implemented, which has proven to be useful for optical measurements, and is capable of achieving the same level of accuracy as the typical absolute measurement methods. Furthermore, the effects of measurement noise, the …

Evaluation of a Developmentally-Based Music Therapy Tool for Children with Autism
… (r X i). The g coefficient for the ADSA tool for absolute measurement was 1.00, which surpassed the conventionally accepted reliability value of .80.

Ultrafast Ionisation Dynamics Induced by Short Proton Pulses
… from high-power laser-solid interactions. The absolute measurement of proton bursts as short as 3.7 ± 0.7 psis reported, enabled by the ultra fast decay pathways available to excited electrons in the formation of self-trapped excitonic states.The role of defects in the recovery of an induced …

Theoretical and Experimental Study of Low-Finesse Extrinsic Fabry-Perot Interferometric Fiber Optic Sensors
… large dynamic range, and the capability of absolute measurement at the same time, while others either have less resolution, or are not capable of absolute measurement. Very different from SMF-EFPI sensors, MMF-EFPI sensors with high fringe visibility usually are more difficult to obtain in …

The neutron sensitivities of Geiger-Müller counters
… separate doses are usually determined by making measurements with two instruments which have different sensitivities to the two types of radiation and deducing the separate components from these measurements. One instrument usually has approximately equal sensitivity to both neutrons and gamma …

Measuring the charged pion and kaon contributions to the T2K neutrino beam in neutrino and antineutrino running modes using ν μ and ν ̄ μ CC inclusive selections in the ND280 detector
… uses flux models constrained by external measurement from the NA61/SHINE experiment [1] [2]. Despite this, an in-situ measurement is required to confirm the flux model derived from the NA61/SHINE data, account for time variations and any other differences between the modelled and actual …

Measuring the Frequency of Light using Femtosecond Laser Pulses
… and refined. For all time and frequency measurements the SI second defined by the cesium ground state hyperfine splitting near 9.2 GHz is the defined standard of reference. Therefore in precision optical frequency measurements optical frequencies on the order of several 100 THz – too fast …

High Speed Fiber Optic Spectrometer
… with small dynamic range, medium accuracy and measurement ambiguity. The white light interferometry could provide a solution for high accuracy and large dynamic range measurement without ambiguity because of its absolute measurement nature. However the signal demodulation speed is limited due …

High-performance velocity, frequency and time estimation using GNSS
… However, many applications exist in which the measurement of both velocity and/or time is crucial and this is the reason why the focus of this thesis is on the Velocity and Time solution. The PVT solution is computed through trilateration techniques, based on a TOA (Time Of Arrival) ranging …
