Mt. Sanqingshan Geopark in Jiangxi is famous for its granite peak-forest landforms in the world. Low temperature thermal-chronology is used to analyze the uplifting and denudation process of Mt. Sanqingshan in the paper. The fission track ages can be divided into three groups, which can be related to...

To further increase the hiding capacity of MP3 files, an improved algorithm is proposed in this paper. Compare to previous work, this algorithm searches out additional 10 Huffman codeword pairs which meet the transparence requirements. With the newly found pairs, the hiding capacity is increased and...

Binary adder is an important module for microprocessors. We present a novel structure of binary adder, named Hyper-Parallel Prefix Adder (HPPA) in this paper. The basic idea of HPPA is to divide the addition into two levels, both of which are parallel prefix adder architecture. It can perfectly reduce...

After researching many protection methods for releasing sensitive information, we found that differential privacy could provide strong guarantees on it, but it will adding too much noise and spending too much times in releasing dynamic set-valued data. To solve these problems, this paper present a privacy...

Detecting an overlapping and hierarchical community structure can give a significant insight into structural and functional properties in complex networks. In this paper, we propose an improved algorithm to detect communities in the complex network. The proposed algorithm use discrete cosine transform...

In this paper, by the application of Turbo principle, a new parallel interference cancellation and decoding (PIC/decoding) algorithm for convolutionally-coded multi-carrier DS-CDMA (MC-DS-CDMA) is proposed. We give a detailed description of the proposed algorithm, and further mathematical analysis is...

The energy of the laser can be greatly reduced, the transmission distance and transmission quality would be affected due to the absorption and scattering of raindrops when transmitting in the rain. Based on Beer-Lambert Law and Mie scattering theory, the impact of raindrop spectrum on 1.06um laser transmission...

The hydrophilic acrylic acid was used to modify the glass by grafting acrylic acid onto the plasma treated glass surface under the catalyzer of H2SO4. The results were analyzed from two aspects of composition and structure by attenuated total reflection FTIR ( ATR-FT-IR) and tensiometer ,respectively....

In this paper, three fatigue models are employed and proposed for modeling the fatigue life of different fiber-reinforced composite material systems. In order to identify the unknown parameters in these models, Genetic Algorithm (GA) is used for estimating its values. This technique is a stochastic process...

In order to achieve the stable control for a double inverted pendulum system, linear quadratic Gauss optimal control was applied. Based on separation principle of LQG, firstly, the control law was proposed by the optimal control, and then a state feedback was obtained; whereas, the states of a system...
