In mountainous, cold temperate and polar sites, the presence of snow cover can affect relative seismic velocity changes (dV/V) derived from ambient noise correlation, but this relation is relatively poorly documented and ambiguous.In this study, we analyzed raw seismic recordings from a snowy flat field site located above Davos (Switzerland), durin
The 10 inch inverted pendulum has been considered a classical control problem.Two designs of inverted pendulum are planar and rotary with a nonlinear unstable system characteristic.Inverted pendulum systems are nonlinear.They can be used for testing and studying various observers and controllers.Control of a rotary inverted pendulum is studied here
Membrane separation technology provides an alternative to traditional thermally driven separations, owing to its advantages including low cost, energy-savings and environmental friendliness.However, the current membrane technology for gas separations using Hat polymeric materials suffers the challenge of gas permeability-selectivity trade-offs.To o
Background.The timing of eruption of permanent teeth can be a precious help to the pediatric practitioner in identifying an appropriate treatment plan.Usually, it presents a more precise sign of an early or late growth of the child.Aims.It is to determine whether the timing of the permanent teeth eruption in Lebanese pediatric population can be con
It is demonstrated numerically that a metamaterial-inspired, low profile (height approximately λ/80), electrically small (ka = 0.45) Huygens source antenna can be designed to radiate at 300 MHz in its broadside direction with a high radiation efficiency and a large front-to-back ratio.Two electrically small, near-field resonant parasitic (NF
