The Mechanics of 3D Multi-body Contact System of Long Shell and Tyres
Liang Xiaoling,Xiao Yougang,Li Xuejun
Strategic Study of CAE 2005, Volume 7, Issue 12, Pages 41-44
According to the high iterative feature of shell and tyre structure, the multi-level substructure technique is adopted to set up the multi-body contact model between tyres and long shell. Applying parametric quadratic programming method, the multi-body contact FEM analysis of the No.2 rotary kiln in Henan Branch of China Aluminum Company is done, and the conclusions are as follows: The equivalent stress of shell at supports changes 5 times, and at other parts changes 4 times; the strength of shell at supports is weak, and at other parts is affluent; the strength of shell at the supports 2 and 3 is the weakest.

The Application of Multi-agent Based Distributed Intelligent Control in VAV Air Conditioning System
Zhang Hongwei,Wu Aiguo,Sheng Tao
Strategic Study of CAE 2006, Volume 8, Issue 7, Pages 58-62
A VAV system can be treated as a multi-agent system. In this paper, a multi-agent-based distributed intelligent control method is presented to solve the problem of concordance and decoupling in the VAV system. A simulation program of VAV system is set up for control analysis. Through a simulation, this control method has been proved to be satisfactory.

The reserve space of carbonate reservoir is complex and various in Puguang Gas Field, so the traditional hydrocarbon prediction methods can not get better results. The paper used the structural characteristics of seismic data volume to predict hydrocarbon reservoir, which took relationship between seismic data components on each seismic trace (that is structural characteristics of data volume) as study object to research the characteristics of composition and range of various parameters and their relationship with hydrocarbon bearing ability by detecting the amplitude value of each seismic trace, achieving the goal of predicting the hydrocarbon reservoir. Finally, the method was used to predict reservoir of Puguang Gas Field. The applied results demonstrated that the method can overcome the influence of reservoir nature and can get better results in the prediction of strong nonhomogeneous carbonate reservoir.

In this paper, the number and karyotype of chromosomes, DNA content, the mean nuclear erythrocyte volume, gonads and gametes, embryo development, the mechanism of the tetraploid formation, and the appearance in tetraploid hybrid stocks of the red crucian carp (♀)× common carp (♂)were described. The tetraploid hybrids with stable genetic characteristics were inherited from F3 to F11 and a large population of tetraploid fish had been formed. The tetraploid hybrids were essentially different from their parents-red crucian carp and common carp in chromosome number, reproduction and appearance. Based on the genetic characteristics, the bisexual fertility and reproductive isolation, the tetraploid stocks had possessed the good base to form a new tetraploid species in the future. The formation of the new tetraploid stocks had great significance both in the evolutionary theory of vertebrate and in the production application.

Driftor: mitigating cloud-based side-channel attacks by switching and migrating multi-executor virtual machines Regular Papers
Chao YANG, Yun-fei GUO, Hong-chao HU, Ya-wen WANG, Qing TONG, Ling-shu LI
Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 5, Pages 731-748 doi: 10.1631/FITEE.1800526
Co-residency of different tenants’ virtual machines (VMs) in cloud provides a good chance for side-channel attacks, which results in information leakage. However, most of current defense suffers from the generality or compatibility problem, thus failing in immediate real-world deployment. VM migration, an inherit mechanism of cloud systems, envisions a promising countermeasure, which limits co-residency by moving VMs between servers. Therefore, we first set up a unified practical adversary model, where the attacker focuses on effective side channels. Then we propose Driftor, a new cloud system that contains VMs of a multi-executor structure where only one executor is active to provide service through a proxy, thus reducing possible information leakage. Active state is periodically switched between executors to simulate defensive effect of VM migration. To enhance the defense, real VM migration is enabled at the same time. Instead of solving the migration satisfiability problem with intractable CIRCUIT-SAT, a greedy-like heuristic algorithm is proposed to search for a viable solution by gradually expanding an initial has-to-migrate set of VMs. Experimental results show that Driftor can not only defend against practical fast side-channel attack, but also bring about reasonable impacts on real-world cloud applications.

Strategic Study of CAE 2002, Volume 4, Issue 6, Pages 9-12
There is not any large deposit associated with giant layered igneous complex in China. But superlarge and large magmatic deposits have been discovered in many small intrusions. Therefore, research and exploration direction having great potentialities for the magmatic deposits of small intrusions is defined. The Jinchuan and Panzhihua deposits represent two important types of the magmatic deposits in China.

Strategic Study of CAE 2005, Volume 7, Issue 12, Pages 74-77
Based on the characteristic of malleable iron, the technology of multistage heat treatment for malleable iron was investigated successfully. Compared with the present technology, the time of graphitizing annealing using new process was saved about 50% . The microstructure, with uniform distribution of fine polycrystal of graphite nuclei and full elimination of carbide, was obtained. Comprehensive mechanics performance of product exceeded that of present international standard . Two brands of KTH400 — 12 and KTZ750 - 02 can be added on the base of present international and “malleable iron” standards. Those products, such as line tool, pipe fitting for railway, engine piston of car etc, with better performances and credible qualities treated by the technology, were welcomed by users.
