Subaqueous “yardangs”: Analogs for aeolian yardang evolution
[1] Landforms, morphologically similar to aeolian yardangs but formed by erosion of bedrock by currents on an estuarine rock platform, are described for the first time. The geometries of the “yardangs” are described and related to semi-lemniscate shapes that minimize hydraulic drag. The processes of bedrock erosion by the reversing sedimentladen tidal currents are described, and a semi-quantita...
متن کاملSubaqueous sediment gravity flows undergoing progressive solidification
Highly concentrated sediment flows may occur following failures of loosely compacted, granular slopes underwater or in waterfront areas. The mobility of such sediment flows is of considerable interest to the integrity of coastal fills, underwater pipelines and other such marine facilities. However, the physics of highly concentrated sediment-water mixtures is complex in nature and calls for mor...
متن کاملAnalysis on Applications of Network Technology in Subaqueous Sensor System
For the quick development of wireless sensor network and more attention for marine cause from every country, study of the application of network technology in subaqueous sensor system has been the hot topic. The subaqueous sensors network is mainly made up of a great number of sensor nodes and few workstations. These nodes can obtain important information such as the salinity, water temperature...
متن کاملTunnels in digital objects
An important concept in digital geometry for computer imagery is that of tunnel. In this paper we obtain a formula for the number of tunnels as a function of the number of the object vertices, pixels, holes, connected components, and 2 × 2 grid squares. It can be used to test for tunnel-freedom a digital object, in particular a digital curve.
متن کاملEnzymes with molecular tunnels.
As a result of recent advances in molecular cloning, protein expression, and X-ray crystallography, it has now become feasible to examine complicated protein structures at high resolution. For those enzymes with multiple catalytic sites, a common theme is beginning to emerge; the existence of molecular tunnels that connect one active site with another. The apparent mechanistic advantages render...
