The United States and Korea have vast national bridge inventories that require vigilant inspection and repair. With a new generation of sensing technologies and computational tools emerging from interdisciplinary research between civil engineering and other engineering disciplines, bridge management strategies are rapidly improving. Foremost among the new sensors are wireless sensors, EM stress...

As researchers continue to explore wireless sensors for use in structural monitoring systems, validation of field performance must be done using actual civil structures. In this study, a network of low-cost wireless sensors was installed in the Geumdang Bridge, Korea to monitor the bridge response to truck loading. Such installations allow researchers to quantify the accuracy and robustness of ...

This paper introduces an information system for estimating lifetime characteristics of elements of bridges and predicting the future conditions of networks of bridges. The Information System for Bridge Networks Condition Monitoring and Prediction was developed for the Roads and Traffic Authority of the state of New South Wales, Australia. The conceptual departure from the standard bridge manage...

In many current state-of-the-art bridge management systems, Markov models are used for both the prediction of deterioration and the determination of optimal intervention strategies. Although transition probabilities of Markov models are generally estimated using inspection data, it is not uncommon that there are situations where there are inadequate data available to estimate the transition pro...

Knowledge management and e-learning both address the same fundamental problem: facilitating learning in organizations. But they approach the problem with two different paradigms, resulting in two different types of system. This paper proposes context awareness with respect to the learner’s or employee’s context as a solution to bridge the gap. The project Learning in Process is illustrating a s...

In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...
