A certification path is an ordered list of certificates starting with a certificate issued by the relying
party s trust root, and ending with the target certificate that needs to be validated. Certification
path validation procedures are based on the algorithm supplied in ITU-T Recommendation X.509
and further defined in Internet Engineering Task Force (IETF) Request for Comments (RFC)
3280. Certification path processing verifies the binding between the subject distinguished name
and/or subject alternative name and the subject public key defined in the target certificate. The
binding is limited by constraints, which are specified in the certificates that comprise the path,
and inputs that are specified by the relying party. To ensure secure interoperation of PKI-enabled
applications, the path validation must be done in accordance with the X.509 and RFC 3280
specifications. This document provides the test assertions and the test cases for testing path
validation software against these specifications.
base implementaion of the protein (starting from the amino acid sequence) feature extractor used in "L. Nanni and A. Lumini, An ensemble of Support Vector Machines for predicting virulent proteins, Expert Systems With Applications, vol.36, no.4, pp.7458-7462, May 2009. "
This unique guide to designing digital VLSI circuits takes a top-down approach, reflecting the natureof the design process in industry. starting with architecture design, the book explains the why andhow of digital design, using the physics that designers need to know, and no more.Covering system and component aspects, design verification, VHDL modelling, clocking, signalintegrity, layout, electricaloverstress, field-programmable logic, economic issues, and more, thescope of the book is singularly comprehensive.
AVR32801: UC3A3 Schematic Checklist Features • Power circuit • Reset circuit • USB connection • External bus interface • ABDAC sound DAC interface • JTAG and Nexus debug ports • Clocks and crystal oscillators • MMC, SD-card, SDHC, SDIO and CE-ATA interface 1 Introduction A good hardware design comes from a proper schematic. Since UC3A3 devices have a fair number of pins and functions, the schematic for these devices can be large and quite complex. This application note describes a common checklist which should be used when starting and reviewing the schematics for a UC3A3 design.

在汽車發動機起動時，若發動機起動后起動機不能及時斷電，將會燒毀起動機或損壞飛輪齒環；若變速器不在空檔位置起動，則起動機的瞬間動力將使汽車位移，還可能引起交通事故和人身安全。為此介紹一種利用NXP P89LPC901單片機控制的汽車起動保護控制器，通過檢測汽車起動開關、變速箱檔位、發動機轉速，實現對汽車發動機起動過程檢測和保護。起動保護控制器在發動機起動過程中通過采用逐個關閉打開負載系統，解決汽車發動機過程中因起動電流大而對汽車電源的沖擊影響,延長了電瓶壽命。
Abstract:
When the automotive engine is started, the engine start motor and flywheel gear may be damaged， even traffic accidents and personal safeties may be caused by wrong operation or other factors.In order to ensure the automotive engine can be started normally and safely,it is necessary that the protecting measures and methods are considered in the automotive electrical control system.This paper introduces a kind of the automotive engine starting protect controller based on NXP P89LPC901 MCU.The controller can protect the engine starting process by detecting the starter key switch,transmission stall and engine speed.Through the use of close and open load system,the controller can solve the impact on automotive power because of the high-current load in the process of the automobile engine starting, and extend battery life.
