Partial discharge (PD) is one of the major contributors of the problem in high voltage electrical system. It can cause the insulation of a high voltage equipment to fail and lead to catastrophic incident. In a power transformer, detection of PD using acoustic emission technique has been gaining popularity due to its nonintrusive application and capability of locating PD sources. In this research work,...
This paper provides means of improvement on the existing e-learning techniques adopted by NPTEL (National Program on Technology Enhanced Learning) and CDEEP (Centre for Distance Engineering Education Program). Here, a two way model with the name, “Virtual Lecture and Lab Outsourcing Technique” is proposed. The model uses live webcasting and instant messaging as the chief technologies to provide education...
The expectation maximization algorithm is a popular approach to learning Gaussian mixture models from unlabeled data. In addition to the unlabeled data, in many applications, additional sources of information such as a-priori knowledge of mixing proportions are also available. We present a weakly supervised approach, in the form of a penalized expectation maximization algorithm that uses a-priori...
Social insects like ants, bees deposit pheromone (a type of chemical) in order to communicate between the members of their community. Pheromone, that causes clumping behavior in a species and brings individuals into a closer proximity, is called aggregation pheromone. This article presents a new algorithm (called, APC) for pattern classification based on the property of aggregation pheromone found...
Combination of structure and content features is necessary for effective retrieval and classification of XML documents. Composite kernels provide a way for fusion of content and structure information. In this paper, we demonstrate that a linear combination of simple and low cost kernels such as cosine similarity on terms and selective paths provide a good classification performance. We also propose...
Automated Essay Grading (AEG) or scoring systems are not more a myth they are reality. These AI systems are blessings to the educational community where teachers normally face lots of problem while correcting studentspsila essays. Valuation of huge amount of student essays within stipulated time frame, with feed back is a real challenge. But today, the human written (not hand written) essays easily...
