AISI 304 stainless steel categorized under austenitic, has good resistance to corrosion and applicable for high pitting stresses. But it poor hardness, sterngth wear. In order overcome the above problem, various hardening techniques like nitriding, carburizing, carbonitriding, Cyaniding etc are preferred. this work, aqueous soluted nitriding process is carried out improve surface hardness wear ...

For biodiversity research, the field of study that is concerned with the biological diversity of our planet, it is of utmost importance that the location of an animal specimen find is known with high precision. Due to specimens often having been collected over the course of many years, their accompanying geographical data is often ambiguous or may be very imprecise. In this contribution, we det...

Cyclic stress is applied to a soil element in the ground when vehicles or trains pass repeatedly on roads and railway tracks. This cyclic induced by traffic load gives rise settlement, which sometimes causes damage such as cracks ruts road pavement. Therefore, estimating settlement of granular materials necessary for sustainable design. For this study, hollow cylindrical torsional shear apparat...

Grade 630 martensitic precipitation hardening stainless steel has a combination of high hardness and strength after suitable heat treatment. The great advantage this grade is that they are usually supplied in the condition treated with solution then aged to achieve sufficient strength. Chosen for research work, AISI samples were subjected salt bath nitriding process. Three chosen shape tapered ...

The need for effective and reliable damage detection localization systems is growing in several engineering fields, particular water impact problems characterized by impulsive loading conditions, high amplitude vibrations large local deformations. In this paper, we further develop the approach presented previous works to detect of water-impacting structures. Specifically, provide a set experime...

This report introduces QEPCAD B, a program for computing with real algebraic sets using cylindrical algebraic decomposition (CAD). QEPCAD B both extends and improves upon the QEPCAD system for quantifier elimination by partial cylindrical algebraic decomposition written by Hoon Hong in the early 1990s. This paper briefly discusses some of the improvements in the implementation of CAD and quanti...
