Analysis and Simulations of Inertia Force in Ultra High Speed Stamping Machine

Jianyu Bai, Zaihe Yu, Di Zheng

Abstract—Based on analysis and simulations, it is found that extremely high inertia forces will be generated in stamping machine when stroke speed falls in range for ultra high speed stamping machine if a regular crank-slider mechanism is used. This paper presents a …

A Novel Grayscale Watermarking Algorithm

Jianyu Bai, Feng Liu

In this paper,a novel grayscale watermarking algorithm based on Two-Level Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD) is proposed. The watermark signal is (32 × 32 × 8) bit gray image.First,The original image is divided into blocks according to the …

Carrier frequency estimation in automatic modulation recognition environment

Zaihe Yu, Jianyu Bai

Carrier frequency estimation is important in both cooperative and non-cooperative communications. This paper addresses the estimation of the carrier frequency of a single-tone digitally modulated signal in the automatic modulation recognition (AMR) environment, where the AMR receiver does not have priori knowledge …
