We propose a generalized Sparse Representation-based Classification (SRC) algorithm for open set recognition where not all classes presented during testing are known during training. The SRC algorithm uses class reconstruction errors for classification. As most of the discriminative information for open set recognition is hidden in the tail part of the matched and sum of non-matched reconstruction...
Vehicular Ad Hoc Networks (VANETs) are more attracted research topic for research community in recent years. The IEEE 802.11p defined by Wireless Access in Vehicular Environment (WAVE) standard for MAC layer implementation in VANETs. IEEE 802.11p uses Collision Sense Multiple Access (CSMA) mechanism and fixed Service Channel Interval (SCHI), Control Channel Interval (CCHI) for access channels. Due...
Periodic inspections are necessary to keep railroad tracks in state of good repair and prevent train accidents. Automatic track inspection using machine vision technology has become a very effective inspection tool. Because of its non-contact nature, this technology can be deployed on virtually any railway vehicle to continuously survey the tracks and send exception reports to track maintenance personnel...
When a database system is extended with the skyline operator, it is important to determine the most efficient way to execute a skyline query across tables with join operations. This paper describes a framework for evaluating skylines in the presence of equijoins, including: (1) the development of algorithms to answer such queries over large input tables in a non-blocking, pipeline fashion, which significantly...
This paper describes new methods for dividing a power network into zones, such that buses are electrically close to other buses within zones. Defining zones based on electrical distance rather than asset ownership or historical affiliation has the potential to improve the utility of planning procedures, such as Load Deliverability Assessment, that are based on zone boundaries. The paper describes...
Power sector is one of the important infrastructures, which gets affected due to disasters leading to disruption in generation, transmission and distribution of electric power. One of the reasons is the deposition of pollutants on the insulators which start conducting during foggy weather conditions resulting in flashover and interruption of power. Amongst the non-ceramic insulators, silicone rubber...
