Bounded Dynamic Source Routing in Mobile Ad Hoc Networks

Description: A mobile ad hoc network (MANET) is a collection of mobile platforms or nodes that come together to form a network capable of communicating with each other, without the help of a central controller. To avail the maximum potential of a MANET, it is of great importance to devise a routing scheme, which will optimize upon the performance of a MANET, given the high rate of random mobility of the nodes. In a MANET individual nodes perform the routing functions like route discovery, route maintenance … more

Characterization of Methyltrimethoxysilane Sol-Gel Polymerization and the Resulting Aerogels.

Description: Methyl-functionalized porous silica is of considerable interest as a low dielectric constant film for semiconductor devices. The structural development of these materials appears to affect their gelation behaviors and impact their mechanical properties and shrinkage during processing. 29Si solution NMR was used to follow the structural evolution of MTMS (methyltrimethoxysilane) polymerization to gelation or precipitation, and thus to better understand the species that affect these properties an… more

The Concept of Dignity in the Early Science Fiction Novels of Kurt Vonnegut.

These works use supercomputers, aliens, and space travel, often in a comical manner, to demonstrate that the future, unless people change their concepts of humanity, will not be the paradise of advanced technology and human harmony that some may expect. In fact, Vonnegut suggests that the human condition may gradually worsen if people continue to look fur… more
