Today, an innovative leap for wireless sensor networks, leading to the realization of novel and intelligent industrial measurement systems, is represented by requirements arising from Industry 4.0 Industrial Internet Things (IIoT) paradigms. In fact, unprecedented challenges capabilities are being faced, with ever-increasing need collect reliable yet accurate data mobile, battery-powered nodes ...

The thermal cyclic behavior of self-healing barrier coatings (SH-TBC) is analyzed numerically to develop a lifetime prediction model. Representative microstructures are studied adopting unit cell based multiscale modeling approach along with simplified evolution model for the thermally-grown oxide layer (TGO) study damage and healing in TBC system. fracture process modeled using cohesive zone-b...

Semi-structural bonded joints of steel components are exposed to long-term stresses in addition water diffusion, temperature changes and varying external forces during operation. These hygro-thermomechanical loadings lead successive degradation stiffness strength due damage resulting from chemical aging fatigue processes, causing failure the joint when its service life is reached. In following ...

In reliability theory, risk analysis, renewal processes and actuarial studies, the residual lifetimes data play an important essential role in studying the conditional tail of the lifetime data. In this paper, Based on some observed ordered residual Weibull data, we introduce different prediction methods for obtaining prediction intervals of future residual lifetimes including likelihood, Wald,...

cognitive performance such as prediction and reaction time changes along with aging. it seems that regular lifetime physical activity depends on the delay of these factors. this study aimed at investigating the effect of pilates training on the improvement of motor performance of sedentary elderly men in kermanshah city. 40 sedentary elderly men (mean age 72.15 ± 6.54 years) were selected from ...

Predictions oflifetimes of dynamically allocated objects can be used to improve time and space efficiency of dynamic memory management in computer programs. Barrett and Zorn [1993] used a simple lifetime predictor and demonstrated this improvement on a variety of computer programs. In this paper, we use decision trees to do lifetime prediction on the same programs and show significantly better ...
