Abstract

The Mobile Ad-hoc Network is a wireless mesh network that is capable of transferring packets within the hosts connected to the network. It lacks an infrastructure, so it makes the system vulnerable as well as flexible. The self reconfigurable network is built up with nodes that are connected to the wireless links, making the transfer of packets possible in the dynamic topology whereas the mobile nodes make the route change. The nodes can be rapidly deployed in the network even for the rapidly changing network conditions. The MANETs are implemented in various application scenarios that include military applications, personal networking areas such as laptops, cell phones, civilian environments, conferences,boats, sports stadiums in small aircrafts and so on. Above all these, MANETs are used for the networks that work more effectively in emergency operations such as search and rescue, firefighting etc. Mobility and multihop are the basic characteristics of the network. There are various protocols supporting the mobile ad hoc networks. This paper shows the comparative study of the unicast, multicast and geocast protocols that is implemented with a heuristic called centre distance priority heuristic, which allows a better scaling on thretransmissions of the packets by providing a priority based queuing system for the hosts inside the network. The geocast system is implemented with the criterion for fixing the zone of relevance that makes the system much more efficient in transmission of packets. AODV protocol is a reactive protocol implemented in common for all the cases. Different parameters are plotted during simulation, comparing the three protocols on the network and the simulation results are graphically represented.

Abstract

One of the applications of Natural Language Processing is Machine Translation. Machine Translation means that by use of software to translate text or speech from one language to another language. Machine translation refers to the use of computers to automate the task of translating between human languages. Machine Translation with Statistical approach helps to do machine translation for any language pair by the use of Statistical tools. This paper describes machine translation with Statistical approach to produce better translation for English to Tamil translation system. We have collected parallel corpus from children story domain. We aligned the sentences manually. SRILM tool kit is used for language modeling. GIZA++ tool is used to build translation model. Moses decoder is used to produce better translation from English text to Tamil text.

Keywords

Statistical Machine Translation, Language Modeling.

Abstract

Breast milk is the first and foremost nutrition a child receives. The enormous benefits of breast feeding have been well documented over the years. However its association with early childhood caries (ECC) has been a constant subject of debate. The etiology of ECC is multifactorial thus posing a difficulty in attributing the risk towards a single factor. The increased duration and frequency of breastfeeding along with poor dietary habits and oral hygiene practices have been reported as contributing factors for ECC. Certain constituents of breast milk have an inhibitory effect on Streptococcus mutans, the major organism implicated in the initiation of ECC. Awareness of ECC and its preventive strategies should be emphasized to young mothers along with the importance of nutrition obtained from breast milk and the benefits of breast feeding. This review is a consolidation of various factors that have been conferred as being associated with breast feeding and ECC.
