Failure mode characterization was applied to coplanar transmission lines by utilizing 0.5–10-GHz S-parameter measurements and post-calculated TDR (Time-Domain-Reflectometry) analysis. Coplanar waveguide transmission lines were inkjet-printed on 1.0-mmthick flexible plastic RF substrates. Inductive, resistive, and capacitive types of failures — as the main failure modes caused by manufacturing, ...

The stability analysis of rock slopes is a complex task for the geotechnical engineers due to the complex nature of the rock mass in a tropical climate that often has discontinuities in several forms, and consequently, in several types of slope failures. In this work, a rock mass classification scheme is followed in a tropical environment using the Rock Mass Rating (RMR) and Geological St...

In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...

Trusses are common structural elements in many industrial and civil buildings. The article describes the approach to planar trusses reliability analysis case of limited statistical data. proposed can be used when it is complicated determine a cumulative distribution function for design loads physical/mechanical properties material elements. method requires only estimates mathematical expectatio...

let r be a fnite commutative ring and n(r) be the set of non unit elements of r. the non unit graph of r, denoted by gamma(r), is the graph obtained by setting all the elements of n(r) to be the vertices and defning distinct vertices x and y to be adjacent if and only if x - yin n(r). in this paper, the basic properties of gamma(r) are investigated and some characterization results regarding co...

Mine closure includes the rehabilitation process, which is a continuous programme aimed at restoring physical, chemical, and biological quality that has been harmed by mining to level acceptable all individuals involved. BIT Mesra was assigned R&D project on development of dragline dump profile both on-going closed mines. As part study, stability highwall investigated for this mine. The final q...
