The paper stochastically investigates a two unit cold-standby system with a server subject to failure and getting delayed treatment thereafter. Semi-Markov process is used to develop the system model. The model is analyzed at different regeneration points using regenerative-point technique. The steady-state expressions are derived for various system performance measures such as mean time to fai...

We analyze a periodically inspected system with hidden failures in which the rate of wear is modulated by a continuous-time Markov chain and additional damage is induced by a Poisson shock process. We derive explicitly the system’s lifetime distribution and mean time to failure, as well as the limiting average availability. The main results are illustrated through two numerical examples.

Carbon fiber reinforced Composite structures posses‟ high strength and stiffness to weight ratios, also exhibits good fatigue resistance, and are less prone to deterioration caused by corrosion and cracking. Fabrication of these composite structures is highly process dependent. During curing process, the physical, mechanical and chemical properties are imparted to the components, and are genera...

conventional implant dentistry has been limited to healed edentulous ridges with adequate bone. predictable success rates resulted in using dental implants in compromised situations such as insertion into old infected sites or near to pathological areas. there is significant data about marginal bone loss and lack of osseointegration around the neck of implants. however, the data about peri apic...

Failures are common in today’s data center environment and can significantly impact the performance of important jobs running on top of large scale computing frameworks. In this paper we analyze Hadoop’s behavior under compute node and process failures. Surprisingly, we find that even a single failure can have a large detrimental effect on job running times. We uncover several important design ...

The rationale for meniscal repair is based on the importance of the meniscus in overall knee function and stability as well as the inferior results seen with meniscectomy. The high success rate usually seen with arthroscopic meniscal repair has made it the treatment of choice for peripheral meniscal tears. This study reviewed the records of patients who have failed meniscal repair surgery to ga...
