Abstract Submarine channels are the largest conveyors of sediment on Earth, yet little is known about their stability in the deep-ocean.Here, 3D seismic data from the deep-ocean Hikurangi channel-levee system, offshore New Zealand, reveal the largest channel-wall failure yet documented.Collapse of both channel-walls along a 68 km stretch created a
Impeller Design and Performance Analysis of Aviation Fuel Pump Based on the Inverse Method
Centrifugal pumps have a wide range of applications in the aviation field.The present work focuses on the optimal design of aviation fuel pump impellers by means of an inverse method.The fuel pump MENS ACCESSORIES impeller is designed here by solving an inverse problem, in which the impeller geometry is found by imposing a target blade loading.As t
Effectiveness and mechanical characteristics of a pile-beam composite structure in blocking debris flows
The pile-beam composite structure in high-elevation debris flow areas is selected as the research object.Based on characterizing the pile-beam composite structure, the particle-flow simulation analysis program and the explicit dynamic analysis program were used to study comparatively the blocking effects of single-row piles and two-row piles, as we
Development and validation of a new method to isolate, expand, and differentiate circulating osteogenic precursor (COP) cells
Circulating osteogenic precursor (COP) cells are a population of progenitor cells in the peripheral blood with the capacity to form bone in vitro Hand Grip and in vivo.They have characteristics of the mesenchymal stem and progenitor pool found in the bone marrow; however, more recently, a population of COP cells has been identified with markers of
A Multiresolution Gray-Scale and Rotation Invariant Descriptor for Texture Classification
Texture classification algorithms using local binary pattern (LBP) CBD Wax and its variants usually can achieve attractive results.However, the selected rotation invariant structural patterns in numerous LBP variants are not absolutely continuous invariant to any rotation angle.To improve the classification effectiveness on this occasion, in this p
