Recently, a friend asked, data warehouse development difficulties.
Do a few years of data warehousing, talk about Data Warehouse Technical Difficulties, I personally think no, what large data query and processing, Data Warehouse ETL process, these are not difficult,The question is whether to think of the problem, take a large amount of data processing, now more and more distributed database vendors, Ncr/dwa and so on, can solve these problems.I think
, complex behavioral decision-making algorithms are mainly FSM, AHP, decision Tree, Fuzzy Logic, Genetic algorithm GA, Ann, Artificial neural network, and specific problems of the particular algorithm, such as Path planning (Ros provides a move-base module, implemented a number of path planning algorithms), generally used in C + + mixed Python programming
Behavioral decision algorithm, there are good solutions, such as the navigation path planning algorithm, but also very difficult, such as th

Atheros wireless cards, generally based on the Atheros AR5001 chipset, are incompatible with driver v4.2.2.9, so that only drive v3.0.1.12 can be used.* Description: This does not include support for the Ar5006ex chip, and until now, WildPackets is not supported for all Athros-based PCI Express cards. OmniPeek itself with three driver versions, this write driver is located in the following directory: Program Files\wildpackets\omnipeek\driver\ Atheros. The Readme file in the driver also contains

In video digitalization, the selection of Brightness Signal Sampling frequency should be considered from the following four aspects:
1) First, the sampling theorem is satisfied, that is, the sampling frequency should be twice the video bandwidth. If the brightness signal bandwidth by is 6 MHz, FS> = 2b = 12 MHz
2) to ensure that the sampling structure is orthogonal, the sampling frequency fs should be an integer multiple of the row frequency FH, that is, FS = N * FH
3) in order to facilitate int
Introduction to ITU-R bt.601
In 1982, CCIR (International Radio Consultative Committee International Radio Advisory Committee) developed the color video digitization standard, known as the CCIR 601 standard, and is now changed to the ITU-R bt.601 standard (601-4: 1994.7. /601-5: 1995.10 ). This Standard specifies the sampling frequency used to convert a color video to a digital image, and the conversion relationship between two color spaces: RGB and YCbCr.Among them, ITU = International
string representing that number is returned. for example, length ("abcde") is five. by contrast, length (15*35) works out to three. in this example, 15*35 = 525, and 525 is then converted to the string "525", which has three characters.
If no argument is supplied, length () returns the length of $0.
NOTE: In older versions of awk, the length () function cocould

480 I, 576i, 720 p, 1080i, and P 1080p are all standard display modes of television. I indicates interlace scanning, and P indicates row-by-row scanning.
525 I is a standard ntsc TV display mode with a frequency of 60Hz, 483 vertical scanning lines, visible vertical scanning lines, or, recorded as I or 525i.
576i is a standard pal TV display mode with a 50Hz frequency, 625 vertical scanning lines, 576 visi
