— A Mobile Adhoc Network (MANET) is a cooperative engagement of a collection of mobile nodes without any centralized access point. The underlying concept of coordination among nodes in a cooperative MANET has induced in them a vulnerability to attacks due to issues like dynamically changing network topology, cooperative algorithms and lack of centralized(More)

Stub This paper talks about a new approach to recognize named entities for Indian languages. Phonetic matching technique is used to match the strings of different languages on the basis of their similar sounding property. We have tested our system with a comparable corpus of English and Hindi language data. This approach is language independent and requires(More)
A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. Wireless sensor networks gather data from places where it is difficult for(More)
This paper presents an unsupervised approach for disambiguating between various senses of a word to select the most appropriate sense, based on the context in the text. We have defined a Probabilistic Latent Semantic Analysis (PLSA) based Word Sense Disambiguation (WSD) system in which sense tagged annotated data is not required for training and the system(More)
BACKGROUND The mechanism and extent of major bile duct injuries following laparoscopic cholecystectomy differ from those of open cholecystectomy. METHODS To identify differences in the demographic profile, timing of injury detection, management strategies and outcome, we undertook a retrospective review and analysis of our experience with 55 major bile(More)
