1 INTRODUCTION Dozens of finite element model updating methods have been studied and suggested but still it remains as a difficult problem. That is because model updating is an inverse process and often contains highly non-linear characteristics. Also the updated result is not unique and depends heavily on the objective function and parameters used in the updating process. Usually, objective fu...

Moran processes are often used to model selection in evolutionary simulations. The updating rule in Moran processes is a birth-death process, i. e., selection according to fitness of an individual to give birth, followed by the death of a random individual. For well-mixed populations with only two strategies this updating rule is known to be equivalent to selecting unfit individuals for death a...

OBJECTIVES To review the current knowledge and efforts on updating systematic reviews (SRs) as applied to comparative effectiveness reviews (CERs). STUDY DESIGN AND SETTING This article outlines considerations for updating CERs by including a definition of the updating process, describing issues around assessing whether to update, and providing general guidelines for the update process. Key p...

An updating version of a visual change detection paradigm was used to investigate the behavioral outcomes and event-related potential (ERP) correlates of visual working memory updating. In each trial, participants were either presented with a memory array followed by a test probe, or with two successive memory arrays. Participants were instructed to update their working memory with the informat...

In this paper, effects of changing ambient temperatures on finite element (FE) model updating of the Dowling Hall Footbridge are investigated. The Dowling Hall Footbridge is located on the Tufts University campus in Medford, Massachusetts. The footbridge is equipped with a continuous monitoring system that records vibration and temperature of the bridge once an hour or when triggered by large v...

Marine industry requires continued development of new technologies in order to produce oil. An essential requirement in design is to be able to compare experimental data from prototype structures with predicted information from a corresponding analytical finite element model. In this study, structural model updating may be defined as the fit of an existing analytical model in the light of measu...

Recently, large-scale distributed systems are being developed. Owing to the high construction cost, the lifetime of the systems are prolonged. Therefore, it is an important problem to achieve exible distributed systems by introducing some mechanism in the system software for updating application software. The system cannot be kept highly available by the conventional updating methods because mu...

We address efficiency issues during the process of integrity maintenance. In this sense, we propose a technique that improves efficiency of existing methods by defining the order in which maintenance of integrity constraints should be performed. Moreover, we integrate view updating into integrity maintenance and we propose a technique for translating view updates efficiently, aimed at reducing ...
