The Mingantu Observing Staion of National Astronomcial Observatories, Chinese Academy of Sciences was officially established in 2008 in Zhengxiang Baiqi, Inner Mongolia of China, about 260 km distance northwest of Beijing. It was reformed by combining Solar Radio Research Group together in 2016. The Mingantu Spectral Radioheliograph (MUSER) is constructed and located there. The MUSER is divided into...
Surveillance cameras have been widely used in different scenes. Accordingly, a demanding need is to recognize a person under different cameras, which is called person re-identification. This topic has gained increasing interests in computer vision recently. However, less attention has been paid to video-based approaches, compared with image-based ones. Two steps are usually involved in previous approaches,...
Field Programmable Gate Array (FPGA) system is widely used in deep learning application and cloud system for acceleration. Quality and reliability of IP block is essential to the successful development of today's complex hardware acceleration design. In this paper, we discuss the important issues of quality and reliability of digital soft IP, and propose a qualification measurement system that can...
This paper presents a very early evaluation and comparison of GPM Level 3 IMERGHH and TRMM3B42V7 final products from 2014/4/1 to 2015/3/31 at daily scale over whole Mekong River Basin (MRB). Daily observation data from 53 in situ rainfall gauges is obtained to do the pixel-point comparison. Two aspects (rainfall amount and occurrence) were taken to evaluate the performance of these two satellite precipitation...
Many predictive resource scaling approaches have been proposed to overcome the limitations of the conventional reactive approaches most often used in clouds today. In general, due to the complexity of clouds, these reactive approaches were often forced to make significant limiting assumptions in either the operating conditions/requirements or expected workload patterns. As such, it is extremely difficult...
The paper describes a procedure to analyze the statistical variation of the radiation pattern of a monopole antenna mounted on an aircraft using physical optics (PO) in comparison to measurements. In the PO simulations, we use the digital model of a turboprop aircraft to calculate the radiation pattern of the monopole antenna. In order to verify the effect of the aircraft on the antenna radiation...
In this paper, we propose a new approach for the person re-identification problem, discovering the correct matches for a query pedestrian image from a set of gallery images. It is well motivated by our observation that the overall complex inter-camera transformation, caused by the change of camera viewpoints, person poses and view illuminations, can be effectively modelled by a combination of many...
Image blur is a common type of image distortion in our daily life. Though traditional image quality assessment (IQA) is increasingly drawing the attention of the research community, the uncertainness and uniqueness which exists in blur images bring unexpected difficulties. We present a simple yet effective automatic method on assessing global invariant blurred images. Different from the traditional...
In a sponsored search market, the problem of measuring the intensity of competition among advertisers is increasingly gaining prominence today. Usually, search providers want to monitor the advertiser communities that share common bidding keywords, so that they can intervene when competition slackens. However, to the best of our knowledge, not much research has been conducted in identifying advertiser...
The aim of the presented activities is to improve the quality and reliability of aircraft bound wide-band satellite transmissions for current and up-coming communication- and air-traffic management applications. To this end, simulation tools are in process of being developed which are based upon an improved model for the transmission channel. Among other influences, the effects of the airborne platform...
This paper introduces a calibration method for measuring the Miniature Current Transformer (MCT) which is based on sampling technology. In this way, we can measure the miniature current transformer with secondary current from 1mA to 100mA and different load accurately.
This paper describes the dielectric material and the structure of standard capacitors developed by NIM, with capacitance range of 1pF to 1µF and the accuracy of 5ppm to 50ppm at 1 kHz. High stability and high accuracy of standard capacitors mainly derives from a choice of dielectric materials which are fused-silica and nano-ceramic. And the capacitors are placed into a constant temperature control...
This paper describes the dielectric material and the structure of the standard capacitance box (decade capacitor) developed by NIM with the capacitance range of 1pF to 0.1µF and the accuracy of 50ppm at 1 kHz. High stability and high accuracy of the standard capacitance box mainly derives from a choice of dielectric materials that are fused-silica and nano-ceramic, and each capacitor in the box contained...
Information-centric networking (ICN) is designed to decouple contents from hosts at the network layer, using in-network caching as a key feature to improve the overall performance. However, the en-route caching strategy used in many ICN implementations generally yields redundancies in the cached contents across different routers. There are also some recent works focusing on cache optimization by respectively...
Information Geometry Metric Learning (IGML) is shown to be an effective algorithm for distance metric learning. In this paper, we attempt to alleviate two limitations of IGML: (A) the time complexity of IGML increases rapidly for high dimensional data, (B) IGML has to transform the input low rank kernel into a full-rank one since it is undefined for singular matrices. To this end, two novel algorithms,...
In Internet Certification Service (ICS), we use the content associated sensitive data extraction technology to increase the security of High Definition video copyright for ICS disc. An important item of ICS is to evaluate the Video Destruction Level (VDL) after extracting sensitive data. This paper presents a flexible and easy simulation environment to calculate the VDL based on DirectShow and Matlab.
Recent technical progress on the Internet and virtual reality has enabled the proliferation of distributed virtual environments (DVEs). In a DVE, high-resolution 3D contents may generate huge data, and the peer-to-peer (P2P) streaming takes advantages to carry these huge traffic in a cost-effective manner. In this P2P paradigm, peers can cache and share DVE data cooperatively to reduce server workload...
Wireless video streaming often suffers from heavy and varying amount of packet loss. Short-length Luby Transform (SLLT) codes are often employed to offer necessary rateless or universal erasure protection. Nevertheless, a proficient method for finding the optimal degree distributions of SLLT codes is still missing although the asymptotic behaviors of infinite-length LT codes have long been deduced...
Metric learning is a fundamental problem in computer vision. Different features and algorithms may tackle a problem from different angles, and thus often provide complementary information. In this paper, we propose a fusion algorithm which outputs enhanced metrics by combining multiple given metrics (similarity measures). Unlike traditional co-training style algorithms where multi-view features or...
The reliability and robustness of Intellectual Properties (IPs) are the keys to the success of the modern System on Chip (SoC) designs. Therefore, it is very important to implement a rigid IP evaluation platform to ensure the reliability of IPs in the SoC design flow. In this paper, we introduce major aspects of IP reliability and present a XML schema based metric model which is able to describe reliability...
