The way river morphodynamics influence the preservation of point-bar deposits at multiple scales is not fully understood. Employing time-lapse trajectories natural rivers, a numerical model used here to simulate planform evolutions meander-belt reaches that embody different transformation behaviors and cutoff processes. Proxies for temporal durations are obtained considering surface area over w...

karun river with a length of about 890 km is considered as a main river in the country. in this paper, types of karun’s screws regarding to the geometric factors of radius of curvature and chord length were identified by fitting circles with the arcs of the river’s axis. river’s arcs were classified into simple and compound screws. then, by formation of the database consist of topographic...

The complexity of large cloud offerings makes it extremely hard to guarantee their dependability and security. This paper extracts lessons from some years of research on the notion of using several clouds – instead of a single one– with the objective of achieving high dependability and security. We show that using such clouds-of-clouds it is possible for services to continue to operate correctl...

To investigate the South Equatorial Current (SEC) in Indian Ocean, 18 drifters were deployed off Sumatra-Java during boreal spring 2019. These drifter observations revealed a large SEC meander that swung southward about 1,100 km 40 days along ∼100°E. The motion occurred on eastern edge of Seychelles-Chagos thermocline ridge, accompanied by an anticyclonic eddy/Rossby wave from east, indicated g...

With the advanced communications systems, integration of 5G bands, including sub-6-GHz and millimeter-wave (mm-wave) bands with existing lower 3G/4G has become an essential need for future mobile handsets. This article proposes between a large-frequency-ratio dual-band tapered slot antenna multisection meander monopole on handset board. The Vivaldi (TSVA) functions as resonant open-ended at low...

At room temperature, the FIB fabricated tungsten meander wire shows positive photoconductivity features through generation of extra charge carriers by absorbing photons required energy from illuminated 532 nm wavelength laser light.
