Modeling of Nonresonant Longitudinal and Inclined Slots for Resonance Tuning in ENZ Waveguide Structures
(Institute of Electrical and Electronics Engineers, 2015)
Novel methods are presented for the independent resonance tuning in rectangular waveguide epsilon-near-zero (ENZ) structures. This kind of tuning is achieved using short longitudinal and inclined slots placed in the middle ...

Vibration-induced dynamical weakening of pyroclastic flows: Insights from rotating drum experiments
(Wiley-Blackwell, 2015)
Pyroclastic flows are characterized by their high mobility, which is often attributed to gas fluidization of the usually fine and/or low-density particles. However, the physical mechanism that might drive sustained ...

Complex flow patterns at the onset of annular electroconvection in a dielectric liquid subjected to an arbitrary unipolar injection
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
We numerically investigated the annular electroconvection that takes place in a dielectric liquid lying between two concentric cylinder electrodes. A uniform injection of arbitrary strengths either from the inner or outer ...

Digital VLSI Implementation of Piecewise-Affine Controllers Based on Lattice Approach
(Institute of Electrical and Electronics Engineers, 2015)
This paper presents a small, fast, low-power consumption solution for piecewise-affine (PWA) controllers. To achieve this goal, a digital architecture for very-large-scale integration (VLSI) circuits is proposed. The ...
