The paired comparison (PC) method is used to investigate reliability, transitivity, and decision time for binary choices among goods and sums of money. The PC method reveals inconsistent choices and yields individual preference order over the set of items being compared. The data reported support the transitivity assumption and demonstrate high reliability for individual preference order. The p...

Structural health monitoring (SHM) has the potential to be an effective way to maintain and improve the public safety of a nation. In recent years, numerous SHM methods have been developed by various researchers. Among these, the damage locating vector (DLV) method proposed by Bernal has received significant attention because of demonstrated efficacy when implemented on a wireless sensor networ...

Accelerated life testing is awidely used tool for assessing the reliability of product components and materials. This paper is ituated in the world of planning such experiments. More specifically, ane w method to plan type I singly censored reliability e xperiments with variable test times will be conside red. A case study is performed in order to illustrate th e method.

One of major reasons of failure of solder joints is known as the thermal fatigue. Also, The failure of the solder joints under the thermal fatigue loading is influenced by varying boundary conditions such as the material of solder joint, the materials of substrates(related the difference in CTE), the height of solder, the Distance of the solder joint from the Neutral Point (DNP), the temperatur...

This paper presents an efficient analytical Bayesian method for reliability and system response estimate and update. The method includes additional data such as measurements to reduce estimation uncertainties. Laplace approximation is proposed to evaluate Bayesian posterior distributions analytically. An efficient algorithm based on inverse first-order reliability method is developed to evaluat...

methodologies to calculate failure probability and to estimate the reliability of fatigue loaded structures are developed. The applicability of the methodologies is evaluated with the help of the fatigue crack growth models suggested by Paris and Walker. The probability theories such as the FORM (first order reliability method), the SORM (second order reliability method) and the MCS (Monte Carl...

Ultrasonic pulse velocity (UPV) and rebound hammer (RH) tests are often used for assessing the quality of concrete and estimation of its compressive strength. Several parameters influence the property of concrete, such as the type and size of aggregates, cement content and the implementation of concrete. To account for these factors, both of the two tests are combined and their measurements are...

This paper describes the challenges of getting ground truth affective labels for spontaneous video, and presents implications for systems such as virtual agents that have automated facial analysis capabilities. We first present a dataset from an intelligent tutoring application and describe the most prevalent approach to labeling such data. We then present an alternative labeling approach, whic...
