Quantitative and Qualitative Reliability Theory in Engineering

Reliability theory is a complex science related directly to engineering, science and economics. Reliability is theoretically defined as the probability of success or the frequency of failures. Reliability engineering deals with the estimation, prevention and management of high levels of lifetime engineering uncertainty and risks of failure.  At present, not only engineers and scientist but also government leaders are concerned to increase the reliability of manufactured goods. We at one of the best universities in Jaipur, JK Lakshmipat university believe that failure prediction can be improved if reliability modeling is integrated in the field of Civil engineering, Mechanical engineering, Computer Science engineering and many more. In order to solve many of engineering problems those arise in reliability theory, the methods of probability theory has been used. Reliability theory introduces quantitative indices of quality of production. Reliability engineering has both Continue reading

Carbon nanotubes are one of the most researched nanomaterials because of their excellent mechanical, electrical and thermal properties.  It consists of carbon atoms covalently bonded in a cylindrical crystalline lattice.  A single wall carbon nanotube consists one cylinder of carbon atoms while multiwall carbon nanotubes have many concentric cylindrical lattices of carbon atoms. Single walled carbon nanotubes (SWCNTs) are much lighter yet many times stronger than steel making them the strongest known material. The Young’s modulus of SWCNTs is in order of 1 TPa, where as carbon fibers have 800 GPa and glass fibers have 70 GPa. Continue reading
