ABSTRACT
A distributed database system is built on standalone mobile databases found on mobile devices. At the heart of the architecture are elected devices that take on the role of data directories which collect the schema of the databases and become the contact points for all nodes that wish to submit queries against the distributed database. The system is implemented on pocket PCs that run the Microsoft WinCE operating system and communicate using Bluetooth.
The most interes ....etc

Abstract
Phase Change Memory (PCM) technology appears as more scalable than DRAM technology. As PCM exhibits access time slightly longer but in the same range as DRAMs, several recent studies have proposed to use PCMs for designing main memory systems. Unfortunately PCM technology su ers from a limited write endurance; typically each memory cell can be only be written a large but still limited number of times (107 to 109 writes are reported for current technology). Till now, research proposals have essentially focuse ....etc

Development of the Carbon Fiber Reinforced Carbon-carbon Composite for High Temperature Gas-cooled Reactors
In the present paper. details of the development of the candidate CIC composite are described. In the material development, especially, feasibility of the production. stableness of the supply and cost are much taken into consideration. As the physical properties of the material, high mechanical strength such as tensile and bending, high fracture strain and fracture toughness and low dimensional change by neutron ....etc

Pulse Code Modulation (PCM)
Principles
Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are more easily separated from noise and can be regenerated in their original state. The conversion of analogue signals to digital signals therefore eliminates the problems c ....etc
