The reliability of smart substations has a great significance on the safety and stability of smart grid operation. Taking the protection system in smart substation as an example, this paper constructs comprehensive reliability models to evaluate the reliability of smart substations with different architectures. The paper first illustrates two important aspects which affect the reliability of th...

An effective analytical approach without Monte Carlo simulation was previously presented by the U.S. Army (Ref. [1]) to evaluate fatigue reliability of helicopter dynamic components. This analytical approach required selection of a reference S/N curve for damage evaluation. Overall reliability of a given life was based on the assumption of weighted sums of the equivalent damage rates of all ste...

OBJECTIVE Pediatric residency programs need objective methods of trainee assessment. Patient simulation can contribute to objective evaluation of acute care event management skills. We describe the development and validation of 4 simulation case scenarios for pediatric resident evaluation. METHODS We created 4 pediatric simulation cases: apnea, asthma, supraventricular tachycardia, and sepsis...

In this paper, we study the probability that a dense network confined within a given geometry is fully connected. We employ a cluster expansion approach often used in statistical physics to analyze the effects that the boundaries of the geometry have on connectivity. To maximize practicality and applicability, we adopt four important point-to-point link models based on outage probability in our...

It is very difficult to built reliability design model of structural parts working in a complex and uncertain environment because of their dynamic time-dependent characteristic, an intelligent method of reliability analysis based on integration algorithm is presented in this paper, RBFNN and finite element analysis combined with Monte Carlo numerical simulation is integrated to improve simulati...

It is customary to assess the reliability of underground oil and gas pipelines in the presence of excessive loading and corrosion effects to ensure a leak-free transport of hazardous materials. The main idea behind this reliability analysis is to model the given pipeline system as a Reliability Block Diagram (RBD) of segments such that the reliability of an individual pipeline segment can be re...

This paper uses a simulation-based optimization framework to investigate the added value of using higherorder distributional information from detailed traffic simulators to address signal control problems. In particular, this paper uses higher-order travel time distributional information to derive signal plans that account for travel time reliability. In order to derive computationally efficien...
