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

用Access算24点
利用Access做用户界面,用Access VBA开发计算24点的程序,然后通过遍历输出所有可能结果。
小学数学老师会利用算24来锻炼小学生的心算能力,作为家长,如果孩子如果有一道题算不出来向您求救时,您却拿不出一个解决方案来,岂不丢面子? 好了,现在有了这个工具,您可以在1秒钟内给出多个答案,孩子会更崇拜您哦! :-)

改进的leach协议算法
LEACH算法是一种无线传感器网络路由协议,leach协议算法基本思想是:以循环的方式随机选择簇头节点,将整个网络的能量负载平均分配到每个传感器节点中,从而达到降低网络能源消耗、提高网络整体生存时间的目的。仿真表明,与一般的平面多跳路由协议和静态分层算法相比,LEACH分簇协议可以将网络生命周期延长15%。
