设A和B是2个字符串。要用最少的字符操作将字符串A转换为字符串B。这里所说的字符操作包括：
1. 删除一个字符
2. 插入一个字符
3. 将一个字符改为另一个字符
将字符串A变换为字符串B所用的最少操作数称为A到B的编辑距离，极为d(A,B)。设计一个算法，计算任意两个字符串的编辑距离。
-Set A and B are two strings. Operation will use the least character string A is converted to a string B. Operation of characters are talking about here include: 1. Delete a character 2. Insert a character 3. Will be replaced by one character to another character will be transformed into a string A string of at least B operand used by A to B is called the edit distance is extremely d (A, B). Design an algorithm to calculate any two of the string edit distance.

RFID indoor location identification for construction projects
资源描述This paper presents a lowcost indoor location identification and material tracking methodology for construction
projects using Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) technology. Onsite
location aware information is an emerging area that focuses on automating delivery of spatial information
pertinent to location of materials, workforce, and equipment. This spatial information can be used to derive
knowledge about construction project status. A two-step algorithm is presented to automate the process of
location estimation and material tracking in near-real-time. In this methodology, a number of passive RFID
tags are distributed onsite where work is progressing, and a mobile RFID reader is carried by a worker onsite.
Each passive RFID tag is deployed as a reference point with a known location (landmark) within a predefined
zone. Reference tags of known locations are used to d

DTMF（Dual Tone Multi Frequency）Recognition Algorithm
Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.
While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for

Apriori 数据挖掘算法 源码
Apriori算法是一种最有影响的挖掘布尔关联规则频繁项集的算法。其核心是基于两阶段频集思想的递推算法。该关联规则在分类上属于单维、单层、布尔关联规则。在这里，所有支持度大于最小支持度的项集称为频繁项集，简称频集。
是：首先找出所有的频集，这些项集出现的频繁性至少和预定义的最小支持度一样。然后由频集产生强关联规则，这些规则必须满足最小支持度和最小可信度。然后使用第1步找到的频集产生期望的规则，产生只包含集合的项的所有规则，其中每一条规则的右部只有一项，这里采用的是中规则的定义。一旦这些规则被生成，那么只有那些大于用户给定的最小可信度的规则才被留下来。为了生成所有频集，使用了递归的方法。
