Local scour is a common threat to structures such as bridge piers, abutments, and dikes that are constructed on natural rivers. To reduce the risk of foundation failure, understanding local phenomenon around hydraulic important. The well-predicted depth can be used reference for structural design river management. Numerical simulation relatively efficient at studying these issues. Currently, tw...

A fundamental challenge in manipulating fabric for clothes folding and textiles manufacturing is computing “pick points” to effectively modify the state of an uncertain manifold. We present a supervised deep transfer learning approach locate pick points using depth images invariance color texture. consider task bed-making, where robot sequentially grasps pulls at increase blanket coverage. perf...

Bridge clogging due to a debris flow is phenomenon scarcely studied but critical in hazard mapping the mountain area. Since rational and systematic approach still missing, we propose practical method deal with this numerical framework. We tested methodology by using, as model, two-phase, mobile-bed model TRENT2D and, site test case, village of Voueces north-west part Italian Alps. The applicati...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

We analyzed the effects of gravitational unloading on muscular fatigability and the effectiveness of resistive vibration exercise to counteract these changes. Changes in knee extensor fatigability as a consequence of 8 weeks of horizontal bedrest with or without daily resistive vibration exercise were evaluated in 17 healthy male volunteers. Bedrest increased fatigability (% decrease in maximal...

Capturing book images is more convenient with a mobile phone camera than with more specialized flat-bed scanners or 3D capture devices. We built an application for the iPhone 4S that captures a sequence of hi-res (8 MP) images of a page spread as the user sweeps the device across the book. To do the 3D dewarping, we implemented two algorithms: optical flow (OF) and structure from motion (SfM). ...
