Underwater scene search turns out to be one of the most challenging topics in the underwater image analysis. In this paper, we present one underwater scene search scheme combined with similarity measure and sparse representation. The color histogram is first adopted to classify the candidate image patches for each kind of the underwater scene. At the same time, the feature similarity (FSIM) consid...Show More
Based on the Maxwell equations, surface charge accumulation on the post-insulator was analyzed. The particle pollution, as well as the generating, recombination, migration and diffusion of the positive and negative ions in the gas were taken into account. Furthermore, from the microcosmic perspective, two surface charge accumulation models of the post-insulator with particle pollution were establi...Show More
A large number of videos are generated and uploaded to video websites (like youku, youtube) every day and video websites play more and more important roles in human life. While bringing convenience, the big video data raise the difficulty of video summarization to allow users to browse a video easily. However, although there are many existing video summarization approaches, the key frames selected...Show More
To address the problem of metal-particle pollution in DC gas insulation, an experimental platform is built for observing the particle's motion and discharge. And the breakdown process is observed using a high-speed camera. Based on the platform, the mechanical analysis of the air-gap breakdown with free spherical metal particles is conducted in a DC uniform field. In addition, different states of ...Show More
Buildings energy consumption is increasing year by year, and the environmental problem is quite serious. So according to the characteristics of hot summer and cold winter in most area of china, buildings heating and air-conditioning, all can be unified in heat pump systems, especially for the office or business buildings, ground source heatpump system can simultaneously solve the heating and refri...Show More
Intellectual property rights (IPRs) sharing and communication are the key impetus factor of the central china innovation and practice. Through the analysis of the influence factor and the question of the technological innovation are in the central china, from the aspect of strategic instruction, the policy support and the technical diffusion system construction, we carry on the innovation analysis...Show More
With feature sizes steadily shrinking, manufacturing defects and parameter variations often cause design timing failures. It is essential that those errors be correctly and quickly diagnosed. The existing delay-fault diagnosis algorithms cannot identify the delay faults that require nonrobust tests, because they ignore nonrobust propagation conditions while emulating the failure analyzer's behavio...Show More
In this paper, we propose a multiple-fault-diagnosis methodology based on the analysis of failing patterns and the structure of diagnosed circuits. We do not consider the multiple-fault behavior explicitly, but rather partition the failing outputs and use an incremental simulation-based technique to diagnose failures one at a time. Our methodology can be further improved by selecting appropriate d...Show More
In modern technologies, process variations can be quite substantial, often causing design timing failures. It is essential that those errors be correctly and quickly diagnosed. Unfortunately, the resolution of the existing delay-fault diagnostic methodologies is still unsatisfactory. In this paper, the feasibility of using the circuit timing information to guide the delay-fault diagnosis is invest...Show More
In modern technologies, process variations can be quite substantial, often causing design timing failures. It is essential that those errors be correctly and quickly diagnosed. In this work, we analyze failures caused by the hold-time-violations. We investigate the feasibility of using circuit-timing information to guide the hold-time-fault diagnosis. We propose a novel and efficient diagnostic ap...Show More

Scientific data classification is the activity of determining whether or not an unlabeled scientific object belongs to an existing class. It is an important operation in the management of scientific databases. The authors present a case study for scientific data classification. Specifically, they develop a tool for DNA sequence classification. The tool works by generating and matching gapped finge...Show More
