Sensitivity studies have shown that density reactivity coefficient, delayed-neutron fractions and decay constants, total core flow, and core power axial shape are the most important parameters that might affect the accuracy of decay ratios.
Secondly, the dynamic system of VPVH tools considering runout is modeled by a periodic-coefficient delay differential equation with multiple underdetermined delays.
The main information elements of a dedicated REM for high-speed rail include the following: channel parameters such as the number of paths, channel coefficients, delay, and angle of arrival for each path at a given position along the high-speed rail line (as illustrated in Table 2), and the local spectrum policy and spectrum usage information, etc.
The reference signals and the disturbance are assumed to satisfy a linear constant-coefficient delay-differential equation of neutral type with discrete delays.
(P2) In Section 4, oscillation properties of equations with different coefficients, delays and initial functions were compared, as well as two solutions of equations with the same delays and initial conditions.
For simplicity and without loss of generality we can consider the zero initial function x xi =0, quad text{for } xi < 0. (1.2) Concerning the coefficients, delays, and function f we assume that f, (a_{i}), (b_{i}), φ, (tau_{i}), (theta_{i}) ((i=1,ldots,m)) are measurable essentially bounded functions ([0,+infty)rightarrow (-infty,+ infty)), and (tau_{i}(t geq 0), (theta_{i}(t geq 0) for (tgeq 0).
The operating frequencies of quartz SAW devices covered with SiAlO2N coatings were only slightly perturbed, but the temperature coefficient of delay (TCD) near 100 °C increased significantly by 250 ppm/°C.
The temperature coefficient of delay (TCD), the phase velocity, and the coupling coefficient of the first three modes of SAWs for different thicknesses of (100) ZnO and (100) AlN are theoretically analyzed.
Dispersions of phase velocities, electromechanical coupling coefficients K2, temperature coefficient of delay (TCD) and sensitivity in the multilayer structures were simulated as functions of normalized thicknesses of ZnO (hZnO/λ) and TeO2 (hTeO2/λ) films.
Then, with the aid of wavelet correlation filtering analysis, the simulated transients with the optimal frequency, damping coefficient and delay time are adaptively peeled from the original bearing fault signal.
