The wheel selection, mentioned in this paper, includes pattern wheels, pattern presser and so on. If the maximum common divisor(δ) of the number of needles on the cylinder (N) and that of grooves on the pattern wheel (T) is equal to T, the machine can knit only walewise stripe; while δ=T/2, only rectangle can be used as a design unit; and while δ≤T/3, either rectangle or several right hexagons can be selected as a design unit according to pattern grid.

The wheel selection, mentioned in this paper, includes pattern wheels, pattern presser and so on. If the maximum common divisor(δ) of the number of needles on the cylinder (N) and that of grooves on the pattern wheel (T) is equal to T, the machine can knit only walewise stripe; while δ=T/2, only rectangle can be used as a design unit; and while δ≤T/3, either rectangle or several right hexagons can be selected as a design unit according to pattern grid. The selection process is discussed in this paper, i.e.we express the pattern matrixes, the bit set-out of pattern wheel groups and the pattern repeat in a two-dimensional digit group respectively, and then establish a mathematical connection among the three digit groups. Thereby, a mathematical basis is provided for CAD of the pattern set-out for the wheel selection. The author has developed a computer software on this basis.

提花轮、台车花压板等都属于提花轮类选针装置。对具有这类选针装置的圆型纬编机来说,当针筒针数N和提花轮槽数T的最大公约数δ=T时,只能编织纵条纹针织物;当δ=T/2时,只能取矩形作为花纹设计单元;当δ≤T/3时,花纹设计单元可在矩形和若干种直角六边形中选取,选取何种应结合构思的图案而定。本文探讨了选取方法,将单元花纹、各提花轮组插齿情况和花纹完全组织分别用一个二维数组表示,然后建立了这三个数组之间的数学关系,这些都为提花轮类选针装置花型上机的计算机辅助设计提供了数学基础。作者在此基础上研制了一个计算机软件。

In the genetic algorithm,gene data is presented as unsigned binary integers.But"0"and "1" in this data are saved as chars in the traditional programming.As a result,the genetic data not only differ from the real storage form in data structure and occupy extra memory,but also make the operation of algorithm as char string operation.This paper presents a binary bit set class programmed in C++ with OOP,which expresses the genetic data in the form of bnary bits,improves data storage form and decreases its...

遗传算法中,基因型串结构数据表示为无符号二进制整数,但在传统程序设计中,数据中的“0”和“1”是以字符(char)形式存储的,这样表示的基因数据不仅在数据结构上和实际存在差异,多占用了内存空间,而且也使算法中的操作实际是字符串操作。利用C++面向对象设计思想,通过引入二进制位集合类,使基因型数据真正表示为二进制位(bit)数据,并改进了数据的存储方式,减少了内存需求,使遗传操作编程更方便。

Based on Petri net,a connection oriented TCP protocol anomaly detection model was established.Based on TCP state transition diagram,the flag bits of packets were systemically analyzed according to TCP protocol specification.So the malformed packets,which abnormally formed by flag bits,such as FINRST packets can be identified.The receivable flag bit set of each state in the model was defined,meanwhile the timeout anomaly of each state was refined,by which varied anomaly can be detected accurately so as to defend the known and unknown abnormal behaviors.With the detection model,not only the known anomalies can be discovered,but also can it protect from unknown attacks.Experimental results show that the quantity of anomalies generated by packets with malformed flag,port scans and DOS attacks will occupy more than 10 percent of the total traffic in networks.

从面向连接的角度出发,以Petri网为工具,建立了TCP协议异常检测模型.该模型以TCP协议的状态变迁图为基础,并根据协议规范可对传输报文的标志位进行系统的分析,从而识别出标志位非法组合构成的畸形报文(FIN-RST报文).模型中规定了各种状态下可接收的标志位集合,同时还细化了各状态下的超时异常,据此可准确地检测出各种异常,以抵御已知和未知的非法行为.利用该模型不仅可发现已知异常事件,还可对未知漏洞进行防范.通过实验发现,网络中的错误标志位报文、端口扫描以及DOS攻击产生的异常流量将占到总流量的10%以上.
