Fourier transform to strike a signal to the power spectrum --- welch method
Power spectrum estimated more than window ---- Law (multitaper method, MTM)
---- Power spectrum estimate of maximum entropy (maxmum entmpy method, MEM)
---- More than the estimated power spectrum signal classification (multiple signal classification, music)
Learn how to build a custom Linux® distribution to use in an embedded environment,
in this case to drive a Technologic Systems TS-7800 single-board computer. In this
tutorial, you learn about cross-compiling, the boot loader, file systems, the root file
system, disk images, and the boot process, all with respect to the decisions you
make as you re building the system and creating the distribution.
四種聚類算法源代碼及示例代碼,本程序的最終目的是形成一套標準的用于聚類、可擴展的工具。包括的內容有1. 聚類算法：Kmeans和Kmedoid算法、FCMclust, GKclust, GGclust算法 2. 評估分類原型：程序可以在二維圖像上繪制出聚類的結果 3. 驗證：程序給每一個算法提供驗證機制，每個聚類算法會統計Partition Coefficient (PC), Classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni s Index (XB), Dunn s Index (DI) and Alternative Dunn Index (DII)幾種衡量指標。
MPI stands for the Message Passing Interface. Written by the MPI Forum (a large committee comprising of a cross-section between industry and research representatives), MPI is a standardized API typically used for parallel and/or distributed computing. The MPI standard is comprised of 2 documents: MPI-1 (published in 1994) and MPI-2 (published in 1996). MPI-2 is, for the most part, additions and extensions to the original MPI-1 specification.
The MPI-1 and MPI-2 documents can be downloaded from the official MPI Forum web site: http://www.mpi-forum.org/.
Open MPI is an open source, freely available implementation of both the MPI-1 and MPI-2 documents. The Open MPI software achieves high performance the Open MPI project is quite receptive to community input.
The TW2835 has four high quality NTSC/PAL video decoders, dual color
display controllers and dual video encoders. The TW2835 contains four
built-in analog anti-aliasing filters, four 10bit Analog-to-Digital converters,
and proprietary digital gain/clamp controller, high quality Y/C separator to
reduce cross-noise and high performance free scaler. Four built-in motion,
