    unix或linux下的DNA分析軟件源碼 其功能如下 1. Edit up to 256 peptide or DNA sequences simultaneously. 2. Translates DNA->protein click next to display next frame. 3. Dot matrix plot of any 2 sequences. 4. Rudimentary amino acid statistics (MW and amino acid percentage) 5. saves matrix plot as PBM image format. 6. Sequence reversal. 7. Creates alignment file for highlight (below). 8. Tab key toggles editing of next sequence.

  • java語言開發的P2P流媒體系統

    java語言開發的P2P流媒體系統,“Stream-2-Stream implements multicast+, a next generation streaming protocol. Multicast+ is more efficient and requires less bandwidth than direct streaming (e.g. shoutcast/icecast). Stream-2-Stream (abbreviated "s2s" or "S2S") stations have no user limit stations can be set up without paying a fortune for bandwidth. Stream-2-Stream saves bandwidth by passing streams from one peer to another through multicast and unicast p2p, rather than everyone getting a stream from one central server (Shoutcast/Icecast). ”更多:http://s2s.sourceforge.net/about.php

  • This is GPS Acquisition..by Matlab, this file performs cold start acquisition on the collected "data

    This is GPS Acquisition..by Matlab, this file performs cold start acquisition on the collected "data". It searches for GPS signals of all satellites, which are listed in field "acqSatelliteList" in the settings structure. Function saves code phase and frequency of the detected signals in the "acqResults" structure.

  • PW5200系列_2.0.pdf規格書下載

    The PW5200A/ PW5200C is high efficiency synchronous, PWM step-up DC/DC converters optimizedto provide a high efficient solution to medium power systems. The devices work with a 1.4MHz fixedfrequency switching. These features minimize overall solution footprint by allowing the use of tiny,low profile inductors and ceramic capacitors. Automatic PWM/PFM mode switching at light loadsaves power and improves efficiency
