闡述了軌道交通列車定位技術(shù)。介紹了在軌道交通系統(tǒng)中列車定位技術(shù)的功能，國(guó)內(nèi)外軌道交通中主要采用的列車定位方法，重點(diǎn)論述了幾種主要定位技術(shù)，并從定位精度、閉塞制式、維護(hù)投資成本、抗干擾等方面進(jìn)行分析比較。提出目前軌道交通定位技術(shù)應(yīng)綜合運(yùn)用，取長(zhǎng)補(bǔ)短，多種方法相互融合，才能滿足軌道交通中對(duì)安全可靠性的要求。
Abstract:
Rail train positioning technology is described. The paper introduces the funetions of the train positioning technology in the rail transit system， the main methods of train positioning do mestic and International rail， and focuses on several key methods， analyzes and compares from the positioning accuracy， block system, maintenance and investment cost， interference and so on， suggested that the current rail positioning technology should be integrated use of positioning method of meriging， learn from each other， to meet the reliability requirements of rail safety.

This white paper discusses how market trends, the need for increased productivity, and new legislation have
accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is
changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to
market. This allows FPGA users to design their own customized safety controllers and provides a significant
competitive advantage over traditional microcontroller or ASIC-based designs.
Introduction
The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in
cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas
around machines such as fast-moving robots, and distributed control systems in process automation equipment such
as those used in petrochemical plants.
The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of
electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing
safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was
developed in the mid-1980s and has been revised several times to cover the technical advances in various industries.
In addition, derivative standards have been developed for specific markets and applications that prescribe the
particular requirements on functional safety systems in these industry applications. Example applications include
process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC
62304), automotive (ISO 26262), power generation, distribution, and transportation.

DIGITAL IMAGERY is pervasive in our world today. Consequently,
standards for the efficient representation and
interchange of digital images are essential. To date, some of
the most successful still image compression standards have resulted
from the ongoing work of the Joint Photographic Experts
Group (JPEG). This group operates under the auspices of Joint
Technical Committee 1, Subcommittee 29, Working Group 1
(JTC 1/SC 29/WG 1), a collaborative effort between the International
Organization for Standardization (ISO) and International
Telecommunication Union Standardization Sector (ITUT).
Both the JPEG [1–3] and JPEG-LS [4–6] standards were
born from the work of the JPEG committee. For the last few
years, the JPEG committee has been working towards the establishment
of a new standard known as JPEG 2000 (i.e., ISO/IEC
15444). The fruits of these labors are now coming to bear, as
JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been
approved as a new International standard.

The extraordinary growth of the World Wide Web has been fueled by the ability it gives authors to easily and cheaply distribute electronic documents to an International audience. As Web documents have become larger and more complex, however, Web content providers have begun to experience the limitations of a medium that does not provide the extensibility, structure, and data checking needed for large-scale commercial publishing. The ability of Java applets to embed powerful data manipulation capabilities in Web clients makes even clearer the limitations of current methods for the transmittal of document data.

DES( Data Encryption Standard)算法，于1977年得到美國(guó)政府的正式許可，是一種用56位密鑰來(lái)加密64位數(shù)據(jù)的方法。
IDEA是International Data Encryption Algorithm 的縮寫,是1990年由瑞士聯(lián)邦技術(shù)學(xué)院來(lái)學(xué)嘉X.J.Lai 和Massey提出的建議標(biāo)準(zhǔn)算法稱作PES( Proposed Encryption Standard) 。Lai 和Massey 在1992 年進(jìn)行了改進(jìn)強(qiáng)化了抗差分分析的能力改稱為IDEA 它也是對(duì)64bit大小的數(shù)據(jù)塊加密的分組加密算法密鑰長(zhǎng)度為128位它基于“相異代數(shù)群上的混合運(yùn)算”設(shè)計(jì)思想算法用硬件和軟件實(shí)現(xiàn)都很容易且比DES在實(shí)現(xiàn)上快的多。IDEA自問(wèn)世以來(lái)，已經(jīng)經(jīng)歷了大量的詳細(xì)審查，對(duì)密碼分析具有很強(qiáng)的抵抗能力，在多種商業(yè)產(chǎn)品中被使用。
