As a result of mountain permafrost creep, rock glaciers are common features in high-altitude periglacial areas. From practical point view, beyond their localization and inventorying, both the monitoring prediction evolution due to climate changes crucial. One effects change is thickening basal shear zone (the portion glacier where most deformations localized), eventually leading development une...

When exploiting the deep resources, the surrounding rock readily undergoes the hole shrinkage, borehole collapse, and loss of circulation under high temperature and high pressure. A series of experiments were conducted to discuss the compressional wave velocity, triaxial strength, and permeability of granite cored from 3500 meters borehole under high temperature and three-dimensional stress. In...

Telecommunication wavelength division multiplexing systems (WDM) demand high fiber-to-fiber coupling to minimize signal loss and maximize performance. WDM systems, with increasing data rates and narrow channel spacing, must maintain performance over the designated wavelength band and across a wide temperature range. Traditional athermal optical design techniques are coupled with detailed thermo...

This paper concentrates on the reflection of plane waves in the mixture of generalized thermo elastic solid half-space. There exists quasi dilatational waves i.e. qP1, qP2, qT and two rotational waves S1, S2 in a two dimensional model of the solid. The boundary conditions are solved to obtain a system of five non-homogeneous equations for amplitude ratios. These amplitude ratios are found to de...

In this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. Given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (FSDT). These equations are so...
