Autor: Jinfu Liu, Lei Liu, Zhengyan Jiang, Linsen Xu, Zhipeng Liu, Lü Zhipeng, Zelin Li

Publikováno v: Jixie chuandong, Vol 46, Pp 17-23 (2022)

Aiming at the application requirements on a variety of complex roads and based on the biological metamorphosis mechanism，a wheel-tracked reconfigurable robot is proposed. The robot includes two motion modes，namely wheel mode and crawler mode. By

Kinematic Analysis of Long Stroke Pumping Unit with Post Pulley

Autor: Sun Wenbin, Zhou Sizhu, Wu Bangxiong, Lü Zhipeng

Publikováno v: Jixie chuandong, Vol 41, Pp 34-38 (2017)

In view of the shortcomings of high peak of crank torque and polished rod load,short stroke and serious wear of steel wire rope,the structural characteristics of the conventional beam pumping unit are analyzed. On the basis of that,the post pulley me

A heuristic method for data allocation and task scheduling on heterogeneous multiprocessor systems under memory constraints

Autor: Ding, Junwen, Song, Liangcai, Li, Siyuan, Wu, Chen, He, Ronghua, Su, Zhouxing, Lü, Zhipeng

Computing workflows in heterogeneous multiprocessor systems are frequently modeled as directed acyclic graphs of tasks and data blocks, which represent computational modules and their dependencies in the form of data produced by a task and used by ot

Branching Strategy Selection Approach Based on Vivification Ratio

Autor: Luo, Mao, Li, Chu-Min, Wu, Xinyun, Li, Shuolin, Lü, Zhipeng

The two most effective branching strategies LRB and VSIDS perform differently on different types of instances. Generally, LRB is more effective on crafted instances, while VSIDS is more effective on application ones. However, distinguishing the types
