We analyze the rel leaf of the Arnoux-Yoccoz translation surface in genus 3. We show that the leaf is dense in the stratum Hp2, 2q but that the real-rel trajectory of the surface is divergent. On this real-rel trajectory, the vertical foliation of one surface is invariant under a pseudo-Anosov map (and in particular is uniquely ergodic), but the vertical foliations on all other surfaces are com...

A geophysical investigation involving the vertical electrical sounding (VES) electrical resistivity methods was carried out around Pydibhimavaram Industrial area Srikakulam district Andhra Pradesh. Vertical Electrical Sounding (VES) using Schlumberger array was conducted at thirteen (13) VES stations. The study was carried out with a view to determine the subsurface layer parameters (resistivit...

We demonstrate, both theoretically and experimentally, a pseudo-random, two-dimensional optical phased array (OPA) concept based on tandem injection locking of 64-element vertical cavity surface emitting laser (VCSEL) arrays. A low cavity-Q VCSEL design resulted in an injection locking optical power of less than 1 μW per VCSEL, providing large OPA scaling potential. Tandem injection locking of ...

failure of the quay walls due to earthquakes results in severe economic loss. because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. this study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

Let F be a foliation of the modular curve, given by the vertical trajectories of the Hecke eigenform. It is shown that F is either a Strebel or a pseudo-Anosov foliation or else can be reduced to the above foliations. An application of the result is discussed.
