  • Concrete has been in use as a primary building material since Roman times. As it is strong in compression but weak in tension, it was used in arches, vaults and walls where it is stressed principally in compression. In the mid-nineteenth century, it was discovered that iron and later steel bars could be embedded in the concrete, effectively giving it tensile strength. This allowed it to be used in beams and slabs, where it worked in bending. Buildings, bridges, retaining walls and many other structures were made in this reinforced concrete.

  • A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed, the material used to make it and the funds available to build it.

  • A superstructure can be thought of as the conduit which carries a roadway over a crossing. Like any other bridge component, the superstructure is comprised of many elements. In the bridge design profession, no other component elicits so much discussion, and even downright controversy, as to the type of elements to be utilized in construction. The structural and geometric complexities of the superstructure component make it one of the most challenging design problems in a bridge engineering project....

  • n my "Word of Greeting" of the first edition of this book which was dedicated to Günter Dufey, I pointed out that I appreciate Günter Dufey as someone who builds bridges between Germany and the United States. Meanwhile, almost 5 years have gone by. Günter Dufey's significance as an academic intermediary between the continents has even increased since then. Due to his efforts, the cooperation be-tween high ranked U.S. business schools and the WHU - Otto Beisheim Hochschule in Germany have been intensified. The joint summer MBA program on the WHU campus is attended by 45 U.S.

  • The use of fibre optic sensors in structural health monitoring has rapidly accelerated in recent years. By embedding fibre optic sensors in structures (e.g. buildings, bridges and pipelines) it is possible to obtain real time data on structural changes such as stress or strain. Engineers use monitoring data to detect deviations from a structure’s original design performance in order to optimise the operation, repair and maintenance of a structure over time.

  • The temperature sensor for an electronic controller may be a length of wire or a thin metallic film (called a resistance temperature device or RTD) or a thermistor. Both types of resistance elements change electrical resistance as temperature changes. The wire increases resistance as its temperature increases. The thermistor is a semiconductor that decreases in resistance as the temperature increases. Because electronic sensors use extremely low mass, they respond to temperature changes more rapidly than bimetal or sealed-fluid sensors. The resistance change is detected by a bridge circuit.

  • This lab focuses on the ability to connect two PCs to create a simple switch-based Ethernet LAN using two workstations. A switch is a networking concentration device sometimes referred to as a multiport bridge. Switches are relatively inexpensive and easy to install. When operating in full-duplex mode, they provide dedicated bandwidth to workstations. Switches eliminate collisions by creating microsegments between ports to which the two workstations are attached. They are appropriate for small to large LANs with moderate to heavy traffic....

  • Weathering steel is NYSDOT’s first choice for steel multi-girder bridges under most conditions. This decision has been made in part because of the cost savings that can be realized due to decreased painting and maintenance requirements. However, recent studies have shown that this may not always be the case. This presentation will discuss some situations where bridges with weathering steel are underperforming and whether or not the situation can be rectified for future applications.

  • Portlets are the small Java applications that run within a portal. Good portlets work independently and also communicate fluently with the portal, other portlets, as well as outside servers and information sources. Using Java's Portlet 2.0 API and portal servers like Liferay, you can build flexible, stable business portals without the design overhead required by other application styles. About the Book Portlets in Action is a comprehensive guide to building portlet-driven applications in Java.

  • Theoretical analysis and computational modeling are important tools for characterizing what nervous systems do, determining how they function, and understanding why they operate in particular ways. Neuroscience encompasses approaches ranging from molecular and cellular studies to human psychophysics and psychology. Theoretical neuroscience encourages cross-talk among these sub-disciplines by constructing compact representations of what has been learned, building bridges between different levels of description, and identifying unifying concepts and principles.
