Interferometric SAR analysis with a time series of images obtained from satellite has been proven to be useful monitoring scheme for geomorphological changes, particularly related the vertical dimension.The success this technique relies on coherence between images.This imposes severe challenges applications in vegetated areas.In study, landslide process site located Liugui, southern Taiwan, is investigated by collected ALOS PALSAR and Sentinel 1A.This heavily vegetated.From Persistent...
Abstract This paper aims to investigate the failure mechanism of a shallow foundation on poorly cemented sandstone and propose an upper bound solution for bearing capacity foundation. A series laboratory material load-bearing model tests with specimens made artificial rock mimic undisturbed natural sandstone. Based tests, behavior progressive mechanisms are investigated. It was found that is distinct from cases hard or soil, exhibits both plasticity brittle characteristics. noted formulas...
A micromechanics approach can successfully model the stress–strain–strength relation of a granular material once microcharacteristics have been obtained. However, it is usually difficulty to determine fabric natural materials. Using stress-dependent model, elastic properties become function geometric and kinetic fabric. Also, wave velocity be related properties. Consequently, this paper proposes methodology for evaluating assembly from set measured velocities. The contains three elements:...
Crack-free Al0.45Ga0.55N epilayers with and without graded-AlxGa1−xN/AlN multi-buffer layers (MBLs) were grown on AlN/sapphire templates by radio-frequency assisted molecular beam epitaxy. A significant reduction in dislocations was achieved the epilayer using MBLs. Transmission electron microscopy Raman spectroscopy analysis revealed that compressive strain of effectively relaxed through inclination edge threading (TDs). The driving force for TDs also discussed.
Diversion weirs are typically constructed to elevate river water levels and thereby increase supplies. Most riverbeds in the western foothills of Taiwan composed soft sedimentary rocks covered with an armor layer varying thickness. Due low rock strength head fall caused by weirs, rapid scouring downstream weir often occurs once is worn away. To estimate scour depth mitigate its damage foundations, processes must be identified correctly. Because different mechanical behaviors water-jet...
