− In this paper a development of an adaptive Kalman filter through a fuzzy inference system (FIS) is outlined. The adaptation is concerned with the imposition of conditions under which the filter measurement noise covariance matrix R or the process noise covariance matrix Q are estimated. The adaptive adjustment is carried out using a FIS based on the whiteness of the filter innovation sequence...

This document addresses the beam time required to achieve the design sensitivity of the PREX experiment. As we elaborate below, a 1% measurement of the neutron radius using an electroweak probe will remain compelling for years to come. We estimate that the recently completed physics run of the PREX experiment will yield a ∼2.5% measurement of the neutron radius. While this is a major accomplish...

Abstract It is suggested that the falloff in Q of the P → ∆ magnetic form factor G∗M is related to the recently observed falloff of the elastic electric form factor GEp/GMp. Calculation is carried out in the framework of a two-body GPD mechanism. The P → ∆(1232) form factor G∗M exhibits a more rapid decrease with respect to Q2 than is typically observed in other baryons [1, 2], such as GMp in e...

Axions, hypothetical particles theorised to solve the strong CP problem, are presently being considered as candidates for cold dark matter constituents. The signal power of resonant-based axion detectors, known haloscopes, is directly proportional their quality factor Q. In this paper, impact use superconductors on performances haloscopes studied by evaluating obtainable particular, surface res...

in this study, analysis is presented in two steps. in the first step, the theoretical s-wave displacement spectra, conditioned by frequency-independent q, was fitted with the observed displacement spectra. therefore corner frequency, moment magnitude and frequency-independent q for each record were estimated simultaneously and the estimate of error is given in the root-mean-square sense over al...
