Introduction

In computer operating systems, demand paging is an application of virtual memory. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it (i.e., if a page fault occurs). This is an example of lazy loading techniques.

The compressed ROM file system (or cramfs) is a free read-only Linux file system designed for simplicity and space-efficiency. It is mainly used in embedded systems and small-footprint systems. Unlike a compressed image of a ....etc

ABSTRACT

With the Information age in full and rapid development, users are becoming accustomed to having immediate access to information. Users demand more capabilities from every kind of electronic devices, more processing power, more features and better connectivity. Users are also realizing the benefits of collaborating with others in their communities to help expand the body of knowledge. One user that understands the benefits of information sharing is the United States Department of Defense. The DoD’s Networks-centric enterpris ....etc

Improving TCP/IP Performance over Third-Generation Wireless Networks
The (3G) wireless networks with high data rates is gradually being deployed. The Transmission Control Protocol (TCP) must be optimised to perform in these networks. This will have a broad and significant impact on data application performance. The parts described in this chapter are :
-adapting to the significant delay and rate variations over the wireless channel and
-a wireless channel and TCP-aware scheduling and buffer sharing algorithm
Windo ....etc

Improving Delay-Tolerant Network Performance Using Forward Routing Information (Java)
Proceedings of IEEE INFOCOM

The development of delay-tolerant networks (DTNs) has attracted significant attention in the recent years. The concept started with the idea of interplanetary internet and later the DTN Research Group (DTNRG) took up the work concerning the architectural and protocol design principles for the DTNs. A DTN can be regarded as a group of highly disconnected networks/regions where the communication environment may be far from ideal ....etc

Improving the Performance of TCP Over Wireless Links

In this thesis, we address the problem of degradation in performance of TCP over wireless links. We propose enhancements to TCP so that it responds to certain control signals from the network. These control signals allow TCP to differentiate packet losses unrelated to congestion from those related to congestion. This enables TCP to react appropriately to different packet losses resulting in improved performance. We developed a network simulator for evaluating the performance of our ....etc

METHODS OF IMPROVING PERFORMANCE OF THE GAS TURBINE
INTRODUCTION:
Gas turbines are used in various applications in different regions of the world. Therefore always tend to find ways to improve the overall cycle of the plant. Cooling of air at the intake helps increasing the density of air flowing into the plant and increases the power output. Several attempts have been made by the researches in new cooling techniques mostly concerned with evaporative coolers, chillers etc. The ....etc

IMPROVING RELIABILITY AND PERFORMANCE OF TRANSMISSION LINE USING FACTS TECHNOLOGY


INTRODUCTION :-
As generation and consumption of electricity has grown, investment in the transmission infrastructure has declined. The grid is aging and few new lines are being built, given high cost and permitting delays. The inability to control power flow on the grid results in poor asset utilization and impedes the growth of the energy market. Uncertainties in transmis ....etc
