SSUM: Smart Server Update Mechanism For Maintaining Cache Consistency In Mobile Environments – Mobile Computing

This paper proposes a cache consistency scheme based on a previously proposed architecture for caching database data in MANETs. The original scheme for data caching stores the queries that are submitted by requesting nodes in special nodes, called query directories (QDs), and uses these queries to locate the data (responses) that are stored in the nodes that requested them, called caching nodes (CNs). The consistency scheme is ....etc

Extensible Firmware Interface
Abstract

A BIOS Alternative There has been rapid evolution of the personal computer platform since the 1980s. But there is one element of the PC that has not changed for the past years, namely the BIOS (basic input/output system). Extensible Firmware Interface (EFI) is the name for a system developed by Intel that is designed to replace the aging BIOS system used by personal computers. It is responsible for the power-on self-test (POST) process, bootstrapping the operating system, and providing an inter ....etc

Firmware



Origin of the term
Ascher Opler coined the term firmware in a 1967 Datamation article. Originally, it meant the contents of a writable control store (a small specialized high speed memory), containing microcode that defined and implemented the computer's instruction set, and that could be reloaded to specialize or modify the instructions that the central processing unit (CPU) could execute. As originally used, firmware contrasted with hardware ....etc

GSM Location Update
Definitions
• Location Area (LA): A GSM network is divided into cells. A group of cells is considered a location area. A mobile phone in motion keeps the network informed about changes in the location area.
• Home Location Register (HLR):The HLR maintains a database for the mobile subscribers. At any point of time, the HLR knows the address of the MSC VLR that control the current location area of the mobile. The HLR is informed about a location area upda ....etc

Abstract.
We present deterministic sub-linear space algorithms for a number of problems over update data streams, including, estimating fre- quencies of items and ranges, ¯nding approximate frequent items and approximate Á-quantiles, estimating inner-products, constructing near- optimal B-bucket histograms and estimating entropy. We also present new lower bound results for several problems over update data streams.
1 Introduction
The data streaming model presents a computational model for a variety of monitoring a ....etc

Abstract
This paper presents a new technique for online identificationof an induction motor rotor time constant. The techniqueis designed for a shaft-sensorless indirect field-oriented controlinduction motor drive with a model reference adaptive system(MRAS)-based speed estimator. The MRAS estimator is sensitiveto the changes in the rotor time constant, and online identificationof that parameter is essential. If rotor parameter error exists, itdoes not only change the achieved rotor speed, but it also changesthe dynamic behavior of the ....etc
