We design a sublinear Fourier sampling algorithm for a case of sparse off-grid frequency recovery. These are signals with the form ; i.e., exponential polynomials with a noise term. The frequencies satisfy and for some . We design a sublinear time randomiz ...
The principle of the superposition of ultrasonic frequency vibrations to conventional machining techniques is known and practiced since the 1950s under the name of ultrasonic machining. Using ultrasonics, many good properties appear including reduced thrus ...
We demonstrate that very high performance, extremely compact, scalar corrugated feedhorns can be designed and constructed by optimizing the excitation and phasing of the HE11, HE12, and HE13 modes near the throat of the horn while limiting excitation of hi ...

Sensing an incoming signal is typically associated with absorbing a portion of its energy, inherently perturbing the measurement and creating reflections and shadows. Here, in contrast, we demonstrate a non-invasive, shadow-free, invisible sensor for airbo ...
We present a flat, visible 1.3-octave supercontinuum generated in a GeO2-doped photonic crystal fiber owing to an overlap of the modulation instability and Raman gain regions resulting in efficient energy transfer to new frequency components ...
Motivated by the problem of inferring the molecular dynamics of DNA in solution, and linking them with its base-pair composition, we consider the problem of comparing the dynamics of functional time series (FTS), and of localizing any inferred differences ...
In this paper, an improved model of the vertical risers of a transmission line is proposed and validated. The proposed improved model, which can be readily implemented in the frame of a classical transmission line formulation, provides accurate results at ...
The ability of nanosecond pulsed DBD actuators to control flow separation was investigated on a NACA 0015 profile for velocities reaching Re = 230,000 (24 m/s). The optimal location for the actuator was determined from oil flow experiments. Moderate voltag ...
The occurrence of standing waves in room dramatically affects the sound rendering in the low-frequency range ([20-200 Hz]), and solutions of the state-of-the-art are incapable to damp such modes over the whole low-frequency band. This talk will present a n ...
In this paper we present the design of a temperature compensated low-tune-voltage-sensitive CMOS ring oscillator in 40nm standard CMOS technology. The oscillator has an overall frequency range from 3.1 GHz to 3.6 GHz. The effect of temperature variations o ...
