With the rising trend in research and development of autonomous vehicles, it is important to keep in mind the cost effectiveness of the system. The cost of high-end sensor technologies being astronomically expensive, the research opportunities are restricted to a select few of high-tech companies and research laboratories such as Google, Tesla, Ford, and the likes of it. Hence our main focus is to...
Word Classification involves grouping the words in a document into clusters. Clustering data sets is a much researched problem. In 2005, Nikhil R. Pal, Kuhu Pal, James M. Keller, and James C. Bezdek proposed A Possibilistic Fuzzy c-Means (PFCM) Clustering Algorithm. The PFCM model gives the membership values and the typicality values, along with the cluster centers. It is a hybrid algorithm of possibilistic...
Wireless sensor network have been broadly used in the fields of target detection and tracking, environmental monitoring, industrial process monitoring and tactical systems. Security and energy efficiency arethe major concerns in the wireless sensor network (WSN) design. This paper develops an energy efficient secure scheme against denial-of-sleep attacks. It is one of the important attacks which cause...
Multiband phased array antennas are required for today's multi-function communication applications. These types of antennas play a major role where space is limited. A Koch array antenna is capable of covering several different frequency bands. Koch arrays can be used to obtain multiband behaviour in which side-lobe ratio and radiation pattern characteristics are held same at several frequency bands...
