Review of Noncontact Ultrasonic Measurement System for Structural Health Monitoring_Crimson Publishers

 Review of Noncontact Ultrasonic Measurement System for Structural Health Monitoring by Makiko Kobayashi in  Crimson publishers :  Open Journal of Civil Engineering Non-destructive testing (NDT) of infrastructure such as bridges and tunnels has become more important since it has aging problem and traffic was heavier than expected. Thin film ultrasonic sensors would be attractive because it is easy to integrate on huge structure. However, NDT of huge structure is still challenging because of sensor accessibility. Semi-noncontact ultrasonic sensors were proposed in this manuscript. 20cm diameter copper coil transmit/receive electrical signal from a pulser/receiver instrument and a thin film ultrasonic sensor and reflected echo from 12.7mm thick steel plate successfully. By this method, measurement using drone could be possible and it increases application possibility for huge infrastructure monitoring. https://crimsonpublishers.com/acet/fulltext/ACET.000569.php For more art...

Review of Timber connections: Connector Plate, Cleats, Studies and Dovetail Connections_Crimson publishers

 Review of Timber connections: Connector Plate, Cleats, Studies and Dovetail Connections by Kristopher Orlowski  Crimson publishers :  Open Journal of Civil Engineering EThe strength of a building relies heavily upon the transfer of load from one connection to another [1,2]. A solid and reliable connection method must be utilized to increase the strength of timber panel and enable the structure to withhold an excessive amount of stress [3-5]. In wood buildings, an effective connection will provide the building with strength and ductility [6]. However, there are many connections needed in a wooden structure therefore an economical and durable connection is required to assemble a prefabricated panel quickly and inexpensively in mass production [6]. https://crimsonpublishers.com/acet/fulltext/ACET.000568.php For more articles in  Open Journal of Civil Engineering  Please click on the link  https://crimsonpublishers.com/acet/

A Brief Survey of Regionalization Modeling; A Bonus from Gauged to Ungauged Basins by Mehdi Sheikh Goodarzi  Crimson publishers :  Open Journal of Civil Engineering  Runoff-rainfall models (r-r) have been widely used to manage water resources during past decades. One of the most important upfront hydrological issues, certainly in r-r prediction, is adopting the best calibration method [1]. Regarding the importance of calibration procedure in hydrological modeling, various types of methods and approaches have been practiced optimizing parameter values from manual and trial-error-based style to entirely automated, heuristic and sophisticated approaches. Automatic calibration approaches usually take advantage of modern search processes and algorithms to fit residual errors among observed and simulated data (using objective functions) to optimize parameter values [2]. In terms of hydrological modeling, particularly distributed models, changes in spatial characteristics of wat...
