The application of probabilistic methods to the life prediction of fatigue vulnerable structures is becoming increasingly important. In-service inspection and repair/replacement can be an effective strategy for decreasing fatigue failure probability. However, inspection introduces additional random variables that must be considered in an overall lifetime reliability assessment. In this study, a...

in this paper we study the zagreb index in bucket recursive trees containing buckets with variable capacities. this model was introduced by kazemi in 2012. weobtain the mean and variance of the zagreb index andintroduce a martingale based on this quantity.

In this paper, we propose a framework for recognizing human activities in our daily life. Since a human activity is represented as a sequence of actions, the actions are recognized from videos and then the frequently-occurring human activities can be extracted from them. We show the experimental results applied to the data taken in a deskwork environment to demonstrate the performance of the pr...

Probability bounds analysis (PBA) provides analysts a convenient means to characterize the neighborhood of possible results that would be obtained from plausible alternative inputs in probabilistic calculations. We show the relationship between PBA and the methods of interval analysis and probabilistic uncertainty analysis from which it is jointly derived, and indicate how the method can be use...

advanced exergy analysis is a tool to split the exergy destruction of the system to achieve a better perspective about the potentials of a system for improvements. in addition, the component interactions and their exergy destruction dependency with the other equipment are investigated through the advanced exergy analysis. for this purpose, it divides the exergy destruction calculated by convent...

introduction: this study sought to assess the effects of amperage (ma) and field of view (fov) on intracanal metal post artifacts and the diagnostic parameters for detection of vertical root fracture (vrf) in teeth with intracanal posts. methods and materials: in this diagnostic study, 80 human single-canal teeth were evaluated by cone-beam computed tomography (cbct). nickel chrome cast posts w...

1. Abstract Reliability-based design optimizations (RBDO) require evaluation of sensitivities of probabilistic constraints. To develop RBDO utilizing the recently proposed novel second-order reliability method (SORM) that improves the conventional SORM in terms of accuracy, the sensitivities of the probabilistic constraints at the most probable point (MPP) are required. Thus, this study present...
