the national bridge stock of iran consists of about 330,000 bridges, of which around 50% are older than 30 years. since 2010, iran road maintenance & transportation organization has started implementing a comprehensive bridge management system in order to manage this aged stock efficiently. to predict future conditions of bridge stock, a heuristic numerical method is presented. this methodology...

This study explores the science, technology, engineering, and mathematics (STEM) community college faculty’s perspectives on Association of College Research Libraries’ (ACRL) Framework for Information Literacy Higher Education (Framework). Previous studies implementation have primarily focused librarians’ efforts. pilot project seeks to bridge gap in STEM views regarding a setting. faculty were...

Networked global learning communities build partnership programs between higher education institutions and high schools which allow students, teachers and professors to attend and work in college preparation programs located in countries outside of their native lands. These educational programs help to promote development of transnational policies and procedure reforms to provide access to univ...

Estimating maximum scour depth is normally required in order to determine the depth of  bridge piles. The present paper uses the SSIIM Software which considers flow and sediment equations in a three dimensional manner. The software models flow field around circular bridge pile by resolving Navier-Stokes three-dimensional equations and k-  method, and by temporary solution of flow field and cont...

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...

In this study, a system for monitoring the structural health of bridge deck and predicting various possible damages to this section was designed based on measuring the temperature and humidity with the use of wireless sensor networks, and then it was implemented and investigated. A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) wa...

This paper describes work from the Bridges to Computing project at Brooklyn College of the City University of New York. This project focuses on the transition from high school to college with the intention of encouraging more students to study some aspect of computer science. The Bridges project has both introduced new undergraduate courses into our computer science curriculum and revised exist...
