In view of the learning and improvement ability of on-line boosting algorithm framework, implemented a target tracking system which mixed color information and Haar-like features together. To solve the shortage of the Haar-like features, first used color histogram equalization to the frame image to enhance the image's color information, then used Bhattacharyya coefficient to calculate the similarity...
In this paper, a 30GHz horn antenna with different feeding structures is discussed based on low temperature co-fired ceramic (LTCC) technology. The antenna with high gain is first designed by analyzing operation mechanisms of horn antennas and its implementation on LTCC structures. Then, radiation patterns are studied under stripline and microstrip feedings. The achieved fractional bandwidth is from...
Quite a few of existing literatures focused on research the inner impact of capital structure on Institutional Investors' Stockholding directly. In this paper, we have made an empirical research on this topic based on Chinese listed tourism companies' data during 2005–2009. The results indicated: (1) institutional investors were willing to hold listed tourism companies' shares with lower asset-liability...
This paper analyzed ⋀ item in the gravitational field equation of Einstein from the perspective of the universe symmetry, pointed out the ⋀ term exists is the ether existence. In the transform of Euclid, allows the physical information superluminal. Ether is light and superluminal information carrier.
We have investigated the electroluminescence (EL) characteristics of a novel yellow emitting material (BTHQZn). According to the device structure of 2T-NATA(20nm)/NPB (20nm)/BTHQZn(30nm)/BCP(10nm)/Alq(20nm)/LiF(5nm)/Al, we can concludes that the maximum luminous efficiency reaches up to 0.37cd/A, and maximum luminance up to 1173cd.m-2. The yellow light emission peak is located at 598nm and the Commission...
In order to study the effect of the thickness of DPVBi on the performance of WOLED, we constructed multilayer organic electroluminescent devices, the structure is ITO/2T-NATA (20 nm) / NPBX (15 nm) / DPVBi (x nm) / Rubrene (0.5 nm) / DPVBi (x nm) / Rubrene (0.5nm) / Alq3 (40 nm) / LiF (0.5 nm) / Al. Such structure takes full advantage of the hole blocking and luminous properties of DPVBi, and it is...
Based on the conditions of a less detective devices and less-function of drug boxes on the current market, this paper presents the design of drug boxes detection device. When drug boxes is moving on the conveyor belt driven by the motor, infrared sensors detect the number of drugs boxes, and according to the number set for the specified packing box. Then the numbers of box is displayed on the LCD...
In order to solve the short-life, frequent failures and other defects of existing general fluorescent lamp ballasts, which is being used in Urban roadside billboards, the paper developed a kind of high-frequency DC / AC converter for driving multiple lamps focused to reduce EMI (Electro Magnetic Interference), reduce costs and improve power factor.
A low-cost intelligent mobile phone-based wireless video surveillance solution using moving object recognition technology is proposed in this paper. The proposed solution can be applied not only to various security systems, but also to environmental surveillance. Firstly, the basic principle of moving object detecting is given. Limited by the memory consuming and computing capacity of a mobile phone,...
