Abstract

We report the effectiveness of LU factorization (also called LU decomposition) as a technique for feature extraction along with naïve Bayes Classifier in recognizing handwritten Odia numerals (a regional language of north-eastern states of India derived from the Devanagari script). Experimental results show that LU factorization could be an alternative choice for feature extraction in pattern classification problems.

Keywords

Abstract

This article presents a study of academic performance evaluation using soft computing techniques inspired by the successful application of K-means, fuzzy C-means (FCM), subtractive clustering (SC), hybrid subtractive clustering-fuzzy C-means (SC-FCM) and hybrid subtractive clustering-adaptive neuro fuzzy inference system (SC-ANFIS) methods for solving academic performance evaluation problems. Modelling of students' academic performance is a difficult optimization problem. We explore the applicability of K-means and FCM, SC, hybrid SC-FCM and SCANFIS clustering methods to the new student's allocation problem, which allocates new students into some classes that consist of similar students and the number of students in each class not exceeding its maximum capacity. The models were combined with fuzzy logic techniques to analyse the students' results. In this article, we have conducted clustering based computational experiments to analyse the effects of the different clustering algorithms like K-means, FCM, SC, hybrid SC-FCM and hybrid SC-ANFIS clustering methods for modelling students' academic performance evaluation. Based on the comparison of the results, it is found that the hybrid SC-ANFIS clustering is better than the other methods.

Abstract

The present study describes the ITK of pest management practiced by the farmers of Tinsukia districts of Assam. The information was collected on the basis of personal interview to each of the farmer through a questionnaire. A total sample of 200 farmers of twenty different villages was selected randomly from three rural developmental blocks of the district. All in about 30 ITKs were collected and documented. The percentage of farmers practicing different ITKs ranged from 11 to 78.65 per cent. Identification of scientifically sound indigenous practices may serve as the input for valid scientific management for large scale use of insect pest management and in generation of low cost, location specific and appropriate technology.

Abstract

Field experiment was conducted to investigate the nature of damage caused by sugarcane plassey borer C. tumidicostalis. Generally, there are two phases of infestation of the pests known as primary and secondary infestation. From the investigation, it was observed that the mean number of internodes damaged was more or less similar (1 to 3 internodes) in both the primary and secondary infestation. The mean number of damaged internode was 1.88, 2.06 and 2.42 which was slightly more in the secondary infested canes with 1.78, 2.56 and 2.74 in August, September and October, respectively. However, there was a great variation in the length of spindle damaged by the larvae in primary and secondary infested cane. Similarly, the mean length of internode damaged was more in primary infested canes than secondary infested canes. The mean proportion damaged length caused by the larvae in primary infested cane was 0.46, 0.45 and 0.41 during August, September and October as against 0.18, 0.13 and 0.16 in secondary infested cane, respectively.

Abstract

An experiment was conducted in the Horticultural orchard of Assam Agricultural University, Jorhat from 2014-15 and 2015-16 to develop IPM module against pest and diseases of potato. Ten different IPM modules were followed against the target pest and diseases. Out of these, the IPM module consisting of soil application of MOC followed by high ridge planting and use of yellow sticky trap followed by application of malathion 5 per cent dust and Ridomil MZ-72 @ 0.01% recorded lowest infestation of mole cricket and red ant with 3.42 and 7.71 per cent, respectively with a highest yield of 248.61 q/ha. Likewise, the per cent increase in yield and benefit cost ratio was observed highest (8.54) in the module with low incidence of late blight and leaf roll disease.
