As emerging technologies converge with urban planning, a revolution of automated, on-demand and ownerless transport beckons. But is the concept of an intelligent city network a deliverable reality, or just sci-fi fantasy?
Yet, according to Siemens senior vice president Steffen Endler, Blade Runner did, if nothing else, correctly anticipate today’s world of rapid urbanisation, rising population, climate change and the birth of the technology-supported smart city. (meer…)

The designer of easy aircraft to use composite fibers in the desired direction, and where exactly in the required quantity. The fibers are embedded in a resin to remain in position and provide the necessary support against deformation. Instead, plywood or sheet metal, which allows only one curvature, creator compound, in which the fibers fixed in two directions. (Son and attack), also incorporated in the resin. This has the advantage of freedom in the shape of double curvature, as shown optimal aerodynamic shape and looks very attractive (aesthetic of the service) required. (meer…)
This new, fourth edition presents practicing engineers with timesaving analysis, design, and detailing methods of primary framing members of a reinforced concrete building. Revised and updated to ACI 318-11, it incorporates seismic and wind load provisions to comply with the International Building Code.
All equations, design aids, graphs, and code requirements have been updated to the current codes. Expanded illustrations of the theory and fundamentals and new timesaving design aids were added to include a wider range of concrete strengths. Also contains a new chapter on sustainable design.
