in this work, ag-cu nanoparticles (with different percentages of copper, 10%, 25%, 50%, 75% cu) were synthesized by wet chemical method. copper(ii) sulfate and silver nitrate were taken as metal precursors, ascorbic acid as reducing agent and anhydride maleic (ma) as a modifier. the prepared nanoparticles were characterized by means of x-ray diffraction (xrd) technique and scanning electron mic...

High Efficiency Video Coding (HEVC) is a proposed video compression standard, a successor to H.264/MPEG-4 AVC (Advanced Video Coding). It aims to substantially improve coding efficiency compared to H.264/AVC High Profile, in which transform unit (TU) has been added as one of the key advanced features, at the expense of traversal computation of transform and quantization quadtree. To release the...

This paper presents a method to improve the calculation of functions which specially demand a great amount of computing resources. The method is based on the choice of a weighted primitive which enables the calculation of function values under the scope of a recursive operation. When tackling the design level, the method shows suitable for developing a processor which achieves a satisfying trad...

Using the operational matrix of an orthogonal function to perform integration for solving, identifying and optimizing a linear dynamic system has several advantages: (1) the method is computer oriented, thus solving higher order differential equation becomes a matter of dimension increasing; (2) the solution is a multiresolution type; (3) the answer is convergent, even the size of increment is ...

An Inertial Measurement Unit (IMU) is a significant component of spacecraft, and its fault diagnosis results directly affect the spacecraft’s stability reliability. In recent years, deep learning-based methods have made great achievements; however, some problems such as how to extract effective features promote training process networks are still be solved. Therefore, in this study, novel intel...
