This paper proposes an efficient and simple architecture for 9/7 discrete wavelet transform based on distributed arithmetic. To derive new proposed architecture, we consider the periodicity and symmetry of DWT to optimize the performance and reduce the computational redundancy. The inner product of coefficient matrix of DWT is distributed over the input by(More)
Forest pests and diseases is very important to forest because it not only restricts the development of forest, but also causes huge economic. Chemical pesticides control the pests and diseases effectively and pollute environment seriously. How to reduce the amount of pesticide is the research hotspot in the field of plant protection. Forest plant protection(More)
The difficulty of active hearing protection system is to mask the dangerous noise energy and retain the useful signal at the same time. Binary mask, which was an effective method to be used in speech segregation, was proposed to micro active hearing protection system. A new gammatone filterbank approximation with less resource requirement was proposed to(More)
Riparian zone is an important component of small forested watershed. Due to the integrate effects of stream water and edge effect, there are obvious difference in composition, structure, and distribution pattern between riparian community and non-riparian community. Community minimum sampling areas are also different. In this study, minimum sampling areas(More)
This study was conducted in the riparian forest of Erdaobaihe River, and the flora of riparian plant communities on the northern slope of Changbai Mountain was researched and analyzed. There were 288 vascular plant species belonging to 169 genera and 68 families, among them, 26 plant species belonging to 16 genera and 11 families were fern, and 262 plant(More)

The possibility of using Evolvable Hardware (EHW) for scheduling real-time traffic in Asynchronous Transfer Mode (ATM) networks have studied in this paper. EHW is hardware built on programmable logic devices and whose architecture can be reconfigured by using genetic learning to adapt to new environments. A novel design is the function-level EHW based on(More)
Three-dimensional (3D) morphometric analysis of cellular and subcellular structures provides an effective method for spatial cell biology. Here, 3D cellular and nuclear morphologies are reconstructed to quantify and compare morphometric differences between normal and apoptotic endothelial cells. Human umbilical vein endothelial cells (HUVECs) are treated(More)
A fuzzy direct adaptive control strategy is proposed for the trajectory tracking control of robotic manipulators. Different to the traditional fuzzy adaptive control method, a generalized hyperbolic model is used to be the fuzzy basis function. The input generalized variables of the fuzzy logic system, derived from the input variables after their(More)
Species pool hypothesis is broadly known and frequently tested in various regions and vegetation types. However it has not been tested in the arid Xinjiang region of China due to lack of data. Here with systematic data from references and field survey, we comprehensively examined species pool hypothesis in this region. Took species richness in 0.1° × 0.1°(More)
