The slope of the shock spectrum at low frequencies is typically evaluated by using a veIl known relationship between the undamped residual shock response spectrum and the 2agnitude of the Fourier.spectrum [1]. This has led to the common belief that the shock response of shocks with a low velocity change, like a ?yrotechnic shock, will have a low frequency .lope of 12 dB/octave. But anyone who h...

In this article, the authors introduce and study the performance of two novel parametric families of Nyquist intersymbol interference-free pulses. Using only two design parameters, the proposed pulses yield an enhanced performance compared to the sophisticated flipped-inverse hyperbolic secant (asech) filter, which was recently documented in the literature. Although the construction of parametr...

Transitions between different inflationary slow-roll scenarios are known to provide short non-slow-roll periods with non-trivial consequences. We consider the effect of quantum diffusion on dynamics in a transition process. Using stochastic {\delta}N formalism, we follow detailed evolution noises through sharp modeled by Starobinsky potential, although some our results apply any transition. fin...

In this paper, a compact ultra-wideband bandpass filter using a back to back Coplanar Waveguide (CPW)-to-microstrip transition structure is proposed. Compared with traditional ultrawideband bandpass filters using hybrid structures, the proposed filter has a sharper selectivity because of two transmission zeros located at the lower and upper edges of the passband, respectively, generated by a mo...

Abstract— The main objective of this paper is the reconstruction of lateral dynamics and both roll angle and steering torque of single track vehicles (motorcycle, scooter, etc.). For that purpose, the well-known motorcycle model developed by Sharp in 1971 is used. This model characterizes the lateral dynamics of a motorcycle [16]. The roll angle is not observable in the obtained structure, for ...

In order to describe foot function during the first weeks of independent walking, spatio-temporal pressure distribution patterns were measured. These data give detailed information about roll-off of the foot, by determining the course of the center of pressure, and about load bearing, by calculating relative vertical impulses under the feet. During those first weeks of independent walking, roll...

The unwanted high threshold voltage (Vt) is the major challenge for metal-gate/high-j CMOS especially at small equivalent-oxide-thickness (EOT). We have investigated the high Vt issue that is due to flat-band voltage (Vfb) roll-off at smaller EOT. A mechanism of charged oxygen vacancies formed by interface reaction was proposed to explain the Vfb roll-off effect. This interface reaction can be ...
