Self-generation of machining precision and its realization in lapping of super precision solid balls

ZHANG Bopeng

《机械工程前沿（英文）》 2008年 第3卷 第3期   页码 348-353 doi: 10.1007/s11465-008-0065-7

摘要： This paper presents the principle of self-generation of machining precision by explaining its basic concept and five necessary conditions for forming a system with self-organization capability. A self-generation system is a kind of system with self-organization capability. The self-generation of machining precision for solid balls with super precision is emphatically explained. From the viewpoint of self-organization, there are three types of systems including system 1 with the self-regulation capability, 2 with the self-determination capability of goals, and 3 with the self-organization capability. Although they are all closed loop control systems, they have different constructions and functions. Necessary conditions for achieving self-generation of machining precision are given. Establishment of the system for machining solid balls with super precision is discussed. Self-generation of machining precision for solid balls with super precision on the basis of the capability of self-removal of errors is presented. Self-generation includes the ability of self-removal of errors for solid balls, convergence of self-removal of errors, self-generation of precision, and self-generating system for the given.

Progress in the research and development of p-xylene liquid phase oxidation process

WANG Lijun, CHENG Youwei, WANG Qinbo, LI Xi

《化学科学与工程前沿（英文）》 2007年 第1卷 第3期   页码 317-326 doi: 10.1007/s11705-007-0058-9

摘要： The process of -xylene liquid phase oxidation to produce purified terephthalic acid (PTA) involves a series of liquid phase radical reactions, chemical absorption, reactive crystallization, and evaporation. A commercial PTA production flow sheet includes a number of unit operations, which construct a complex process system. In this paper, a review of research and development (R&D) works on PTA process carried out in Zhejiang University during recent years is introduced. The works cover the oxidation and crystallization kinetics, gas-liquid mass transfer and evaporation, reactor modeling, database development, novel reactor design, process modeling, simulation, and optimization. The author emphasizes the viewpoint through this case study that chemical reaction engineering should be developed to process system engineering to extend its scope, and particular attention should be paid on reactor and process modeling.

A multiscale-contour-based interpolation framework for generating a time-varying quasi-dense point cloud sequence

Chu-hua HUANG,Dong-ming LU,Chang-yu DIAO

《信息与电子工程前沿（英文）》 2016年 第17卷 第5期   页码 422-434 doi: 10.1631/FITEE.1500316

摘要： To speed up the reconstruction of 3D dynamic scenes in an ordinary hardware platform, we propose an efficient framework to reconstruct 3D dynamic objects using a multiscale-contour-based interpolation from multi-view videos. Our framework takes full advantage of spatio-temporal-contour consistency. It exploits the property to interpolate single contours, two neighboring contours which belong to the same model, and two contours which belong to the same view at different times, corresponding to point-, contour-, and model-level interpolations, respectively. The framework formulates the interpolation of two models as point cloud transport rather than non-rigid surface deformation. Our framework speeds up the reconstruction of a dynamic scene while improving the accuracy of point-pairing which is used to perform the interpolation. We obtain a higher frame rate, spatio-temporal-coherence, and a quasi-dense point cloud sequence with color information. Experiments with real data were conducted to test the efficiency of the framework.

从控制论观点审视有限状态自动机的状态空间优化 Research Article

岳菊梅1,闫永义2,陈增强3,邓鹤2

《信息与电子工程前沿（英文）》 2021年 第22卷 第12期   页码 1551-1684 doi: 10.1631/FITEE.2000608

摘要： 现有大多数关于有限状态自动机（finite state machines, FSM）状态空间的优化方法不便甚至不能给出优化的数学意义。本文将FSM视为逻辑动态系统，借鉴控制论中动态系统平衡点的概念，引入t-等价状态和t-源等价状态概念。基于近年提出的FSM状态转移动力学方程，得到t-等价状态和t-源等价状态的数学描述（该数学描述可类比于控制论中关于动态系统平衡点的充要条件），进而给出该优化问题的数学解释。基于这些数学描述，设计了求解FSM所有t-等价状态和t-源等价状态的两种方法。此外，找到降低FSM状态空间的两种路径。可不借助计算机，仅用纸笔以数学推演方式实现。并且，为使所设计的方法借助计算机能完全以无人值守方式运行，提出一个开放性问题。最后，采用实际语言模型验证了结论的正确性和有效性。
