3-D flow of Herschel-Bulkley fluids
(ASME, 1998)The flow of Herschel-Bulkley fluids through a sudden 3-D square with expansion height ratio of 2:1 is studied numerically by solving the mass and momentum conservation equations along with a continuous constitutive relation. ...

3D Radar Localization via Photonic Chirp Leaky-Wave Antenna Beam Scanning
(2019)We report a photonic frequency-modulated continuous wave (FMCW) radar system that provides 3D localization with a simple radar frontend. This is achieved by exploiting linearly polarized leaky-wave antennas (LWAs) for ...

Active earth thrust on walls supporting granular soils: Effect of wall movement
(IOS Press, 2013)The methods currently used in the design practice of retaining walls supporting granular soils (sand, gravel, silt, and their mixtures) assume that the soil friction angle and, consequently, the active earth pressure ...

Active Fault Diagnosis via Reachable Set Separation using Interval Methods
(2019)This paper presents an optimization-based approach for active fault isolation in linear time invariant systems subject to additive disturbances which are bounded in intervals. We model the evolution of the system states ...
