The “Sand Dunes” moored array in the upper slope of the northern South China Sea provided an unprecedented look at internal solitary wave (ISW) arrival patterns and transformations under shoaling as they propagate northwestward passed the sand dunes. The data sets also shown the underwater ambient noise induced by the ISW. The mode-1 depression ISW could generate the surface wave breaking in the convergence...
Network virtualization allows multiple virtual routers to coexist in the same physical router but offer independent routing services. Each virtual router needs to perform millions of lookups and thousands of updates per second to meet the requirements of high-speed Internet. The coexistence of these virtual routers intensifies scalability challenges to the routing lookup scheme: Can it scale well...
In this paper, we propose a novel GSM-R (GSM for Railway) train control system and method for real-time transmission of data. It includes distributed antenna array, BTS(Base Transceiver Station) in the network side and train locomotive terminal; Distributed antenna array set up along the railway, providing the same fixed frequency signal for the train locomotive terminal in order to make data transmission...
Inflammation is a fundamental biology problem with daily threats to human health. In early inflammatory stage, the most important cell type involved is neutrophil, which represents the most massive leukocyte population. In this paper, we report a 3D reusable microfluidic chip which mimics the capillary endothelial lining and we have made an attempt to imitate the hemodynamic-factor in order to study...
Attribute reduction is an important problem in an information system. The paper proposed a novel method to reduce the redudant attributes in an incomplete information system based on rough set theory. The method introduce the concepts such as upper-approximate relationship and lower-approximate relationship, equivalence relationship, tolerance relationship, attribute significance and so on, to calculate...
A fast duplicate video detection system based on camera transitional behavior and the suffix array data structure is proposed in this work. The main idea is to match video clips according to their temporal structures, and frames corresponding to unique events are marked as anchor frames. To simplify the detection process, we use the camera transitional behavior to indicate unique events. Specifically,...
The slow drying of the photoactive layer in polymer/ZnO nanorod hybrid solar cells is studied as a way to improve device performance. The power conversion efficiency can be further improved to 3.05% with an enhanced fill factor of 55% by slowing the spin coating rate of photoactive layer. With the slower spin coating rate, the films of photoactive layer are thicker, and the polymer chains have longer...
To address the multiplicity and copyright issues on file sharing social networks, we propose a fast video copy detection algorithm using the suffix array data structure in this work. The proposed algorithm consists of two steps. In the first step, we extract robust features which are discriminative yet insensitive to various attacks. Specifically, we develop a compact one-dimensional signature based...
