This paper investigates the solvability of the second-order boundary value problems with the one-dimensional p-Laplacian at resonance on a half-line
Noise measurements were carried out in the Cologne area (Germany), and the resonance frequency of each site was estimated from the main peak in the spectral ratio between the horizontal and vertical component. For 32 of these sites, the thickness of the sedimentary cover was known from boreholes, and a clear correlation between resonance frequency and sediment thickness was observed. A formula ...
Abstract. In the resonance ratio control, the estimation speed of the disturbance observer should have been much faster than the resonance frequency of the controlled system. However, too fast disturbance observer causes implementation problem. In this paper, we give the optimal speed of the disturbance estimation and propose a novel technique, slow resonance ratio control, which enables us to ...
A study of the ν̄-jet mass spectrum in e+p → ν̄X events at center-of-mass energy 300 GeV has been performed with the ZEUS detector at HERA using an integrated luminosity of 47.7pb. The mass spectrum is in good agreement with that expected from Standard Model processes over the ν̄-jet mass range studied. No significant excess attributable to the decay of a narrow resonance is observed. By using bot...
We prove a dynamical wave trace formula for asymptotically hyperbolic (n+1) dimensional manifolds with negative (but not necessarily constant) sectional curvatures which equates the renormalized wave trace to the lengths of closed geodesics. This result generalizes the classical theorem of Duistermaat-Guillemin for compact manifolds and the results of GuillopéZworski, Perry, and Guillarmou-Naud...
The photo-production of nucleon resonances is calculated based on a chiral constituent quark model including both relativistic corrections Hrel and twobody exchange currents, and it is shown that these effects play an important role. We also calculate the first moment of the nucleon spin structure function g1 ( x,Q ) in the resonance region, and obtain a sign-changing point around Q ∼ 0.27 GeV ...
We present a relativistic model for electroweak pion production from nuclei, focusing on the ∆ and the second resonance region. Bound states are derived in the Hartree approximation to the σ − ω Walecka model. Final-state interactions of the outgoing pion and nucleon are described in a factorized way by means of a relativistic extension of the Glauber model. Our formalism allows a detailed stud...
Analysis of resonance frequency in shorted transmission lines with inserted capacitor has been made. The analysis shows a resonance frequency dependence on capacitance position on a shorted transmission line. Two analysis methods are presented to predict the resonance frequency and understand how the inserted capacitor affects the resonance frequency of the shorted transmission line. Using this...
