Advancements in energy technologies created a new application for gas turbine generators, which are used to balance load. This usage also brought challenges maintenance because of harsh operating conditions that make turbines more susceptible random failures. At the same time, reliability requirements equipment high. Reliability-centered based on forecasting remaining useful life (RUL) equipmen...

background: osteoporosis is a serious public health. since the majority of bone mass occurs during adolescence, primary prevention  is important. probably mother’s participation in health education interventions leads to promote health behaviors in children. to assess a lifestyle modifcation intervention focused on mothers and students has an impact on osteoporosis preventive  behaviors in adol...

This work focuses on time-inhomogeneous Markov chains with two time scales. Our motivations stem from applications in reliability and dependability, queueing networks, financial engineering and manufacturing systems, where two-time-scale scenarios naturally arise. One of the important questions is: As the rate of fluctuation of the Markov chain goes to infinity, if the limit distributions of su...
