sequence of multiplications to computeX31. There are always ways with only seven multiplications. The following is one of them: X2 =X×X, X4 =X2 ×X2,X8 =X4×X4,X8 =X4×X4,X10 =X8 ×X2,X20 =X10 ×X10,X30 =X20×X10,X31 =X30 ×X. If Division is also available, we can find a even shorter sequence of operations. It is possible

Description StartingXAnd repeatedly multiplyingX, We can computeX31 with thirty multiplications: X2 =X×X,X3 =X2 ×X,X4 =X3×X,...,X31 =X30 ×X. The operation of squaring can be appreciably shorten the sequence of multiplications. The following is a way to computeX31 with eight multiplications: X2 =X×X,X3 =X2 ×X,X6 =X3×X3,X7 =X6×X,X14 =X7×X7,X15 =X14×X,X30 =X15 ×X15,X31 =X30 ×X. This is not the shortest sequence of multiplications to computeX31. There are always ways with only seven multiplica

Monitoring Center), for example: Telecom 2Mbps ADSL Broadband, 50 meters infrared camera theoretically its upstream bandwidth is 512kbps=64kb/s, and its downlink bandwidth is 2mbps=256kb/.Example: monitoring distributed in 5 different places, the way of cameras in each place: n=10 (20) 1 Monitoring Center, remote monitor and storage of video information, storage time is 30 days. The bandwidth and storage space sizes of different video formats are calculated as follows:Local monitoring points:CI

At first I was connecting a WiFi module to my Arduino uno, but Uno has only one UART and this UART is connected to the USB port. There have been some and very strange problems. After entering the setup mode (M0=1, m1=1), it is indeed possible to set the parameters of the settings are saved successfully, but using C3C3C3 can not get to the version without any return, may be my RX data line without contact issues.Later I will two UART WiFi module commun

One, the difference between the index block and the data block As we all know, indexing can improve retrieval efficiency because of its two-fork tree structure and small footprint, so access speed blocks. Let's calculate a math problem: if a record in a table occupies 1000 bytes on disk, we index one of the 10 bytes of the field, and the record has only 10 bytes of t
