HIGH DEFINITION OPTICAL DISC TECHNOLOGY
Current Media Format
CD’s
Consist of pits and lands stamped out in a spiral pattern on the disc.
A laser then reads the pits and lands.
The change from a pit to a land or a land to a pit indicates a one while no change indicates a zero.
Current Media Format (Cont.)
CD-RW’s
Consist of a metal phase change alloy which when heated can be to change to reflectivity
CD-R’s
Consist of a dye that is applied to the disc.
When a writing laser is shined it change ....etc

3G CDMA - WCDMA and cdma2000
Rules for Efficient Multiple Access
Three laws
 Know the channel
 Minimize interference to others
 Mitigate interference received from others
 Requirements of wireless multiple access
 Channel measurement
 Channel control and modification
 Multiple user channel isolation
Why CDMA?
 Higher capacity
 Improved performance in multipath by diversity
 Lower mobile transmit power = longer battery life
 ....etc

Television systems that have a resolution that meets standards but not considered high definition, this is what Standard-definition television or SDTV refers to. This usually refers to digital television, especially while broadcasting at the same (or similar) resolution as analog systems. In ATSC, SDTV can be broadcast in 704 pixels ? 480 lines with 16:9 aspect ratio (40:33 rectangular pixel), 704 pixels ? 480 lines with 4:3 aspect ratio (10:11 rectangular pixel) or 640 pixels ? 480 lines with 4:3 ratio (and square pixels). The refresh rate can ....etc

INTRODUCTION
This is the Topical report for Task 6.0, Phase 2 of the Advanced Turbine Systems(ATS)
Program. The report describes work by Westinghouse and the subcontractor,
Gilbert/Commonwealth, in the fulfillment of completing Task 6.0.
A conceptual design for critical and noncritical components of the gas fired combustion
turbine system was completed. The conceptual design included specifications for the flange
to flange gas turbine, power plant components, and balance of plant equipment. The ATS
engine used ....etc

Introduction to cdma2000 Standards for Spread
Spectrum Systems


OVERVIEW

The cdma2000 Family of Standards
The cdma2000 family of standards includes core air interface, minimum performance, and
service standards (see 1.3). The cdma2000 air interface standards specify a spread
spectrum radio interface that uses Code Division Multiple Access (CDMA) technology to
meet the requirements for Third Generation (3G) wireless communication systems. The
core air interface standards in the family are [ ....etc

ABSTRACT

In the last years one of the main technological efforts in satellite communications is the integration of digital broadcast services with two-way communications: this is justified by the research of new business perspective and in the increase of technological efficiency.
Traditionally, common air interface (CAI) standards have been rigorously defined in great detail to ensure optimized operation for specific application and to permits the interoperability between the equipment of different manufactures devices. In this context, S ....etc

CDMA2000 is a technology for the development of cdmaOne/IS-95 to 3rd generation services. Also known as IMT-CDMA Multi-Carrier or IS-2000 is the main route for CDMA operators to second-and-a-half ( 2.5G) and third generation (3G) cellular networks. A set of new standards that define the new air interface and the Radio Access and Core Network changes that will enhance network capacity, improve speed and bandwidth to mobile terminals, and allow end-to-end IP services has been created by the standard-setting body behind CDMA2000 known as 3GPP2.

Definition

Compact peripheral component interconnect (CPCI) is an adaptation of the peripheral component interconnect (PCI) specification for industrial computer applications requiring a smaller, more robust mechanical form factor than the one defined for the desktop. CompactPCI is an open standard supported by the PCI Industrial Computer Manufacturer's Group (PICMG). CompactPCI is best suited for small, high-speed industrial computing applications where transfers occur between a number of high-speed cards.

It is a high-performance indust ....etc
