 Abstract

This paper presents a terminal voltage control of a wind turbine Self Excited Induction Generator (SEIG). The wind turbine operates over a wide range of operating conditions, which means that the terminal voltage of the induction generator is not constant. Changing the value of excitation capacitance by controlling the firing angle of SVC under different operating conditions can handle this problem. It is proved that SVC in the form of Fixed Capacitor -Thyristor Controlled Reactor (FCTCR) is used not only provide capacitive excitation for the isolated induction generator, but also it controls its terminal voltage at all different loads with variable speeds of the windmill prime-mover. The terminal voltage had been regulated by adapting the value of the excitation capacitance from Static VAR Compensator (SVC) using Artificial Neural Network (ANN) controller and Genetic Algorithm (GA) Approach. Artificial Neural Networks (ANN) and Genetic Algorithm (GA) Approach with a very simple objective function is proposed to meet the control requirements

 Abstract

This study investigates gender differences in career preferences toward science and technology among tribal adolescents in rural Ranchi, Jharkhand, India. Tribal youth in rural Ranchi face unique socio-cultural and economic barriers. The research aims to understand how male and female adolescents differ in their interest, aspirations, and choice of careers in science and technology fields. A descriptive survey design was used, with data collected from 240 secondary school students (120 males and 120 females). Results reveal gender-based differences, with male students showing higher preference for engineering and technology-related careers. The study discusses socio-cultural influences, educational exposure, and family expectations as contributing factors.

 Abstract

Extremophilic microorganisms inhabiting saline and alkaline environments, as well as cold and high-pressure habitats, represent valuable sources of bioactive metabolites due to their unique adaptive mechanisms and significant biotechnological potential. Members of the genus Nocardiopsis, comprising salt-tolerant and alkaliphilic actinomycetes, exhibit remarkable adaptive capabilities and a strong capacity for the production of extremozymes. This review summarizes the diversity, ecological distribution, physiological adaptations, and amylase production and characterization of Nocardiopsis sp. Overall, the review provides insights into the biotechnological potential of Nocardiopsis sp. isolated from saline niches.

 Abstract

India has been in touch with its neighboring regions much before the advent of civilization in South Asia. With the rise of civilization, new vistas of cultural contact were opened in which the trade and commerce could be identified as the major background over which the religious and political contacts flourished in later times. This contact has been characterized by mutual respect and adaptation, leaving a lasting imprint on Southeast Asian civilization.

 Abstract

Educational level of a population is one of the most important determinants of its quality. Data on literacy and educational levels of the population are collected as a part of the demographic particulars of the household members in most of the survey rounds of the National Sample Survey Organisation. In the 42nd round [ July 1986 - June 1987] a comprehensive survey was carried out by the NSSO to study the extent of participation of children and youth in the formal and non-formal educational systems including drop-outs at various levels. Subsequently, a survey on literacy was taken up during July 1991 - December 1991 during which a schedule was canvassed for ascertaining literacy status of persons. Further during the 52nd round [ July 1995 - June 1996] of the NSSO, information on participation in education was collected. In this study, data on reasons for drop out, available in the NSSO 52nd Round, has been used to analyse the crucial reasons leading to males and females dropping out of formal education at various levels.

 Abstract

The present investigation was carried out at Banana Research Station, Nanded. "Studies on plant geometry and levels of potassium on growth, yield and quality of banana (Musa acuminata L.)", for two trial years. In the present experiment, there were four main treatments of plant density, viz. D1 (1.5 m x 1.2 m), D2 (1.5 m x 1.5 m), D3 (1.5 m x 1.8 m) and D4 (1.5 m x 2.1 m), three sub- treatment of potassium levels, viz. K1 (100 g K2 O/plant), K2 (200 g K2O/plant), K3 (300 g K2O/plant) and thus comprising twelve treatment combinations. The lowest percent incidence of sigatoka (10.14%) was recorded in D41.5 m x 2.1 m (3,174 plants/ha) while the highest percent incidence of sigatoka was recorded (18.86%) in D1 1.5 m x 1.2 m (5,555 plants/ha). The effect of potassium levels on percent incidence of sigatoka was found to be non significant. The interaction effect of plant densities and potassium level on percent incidence of sigatoka was found to be non significant.

 Abstract

The increasing demand for electrical energy and the growing emphasis on sustainable power utilization have accelerated the development of intelligent home energy management systems. This paper presents the design and implementation of a Smart Home Energy Management System (SHEMS) that integrates renewable energy sources with ZigBee-based wireless communication and an Arduino (ATmega328) controller. The proposed system is structured into two major sections: a transmitter unit and a receiver unit. The transmitter unit consists of a solar panel, charging control circuit, 12 V battery, voltage and current sensors, relay-based load control, and an ATmega328 microcontroller. It continuously monitors energy generation, battery status, and load consumption, while transmitting real-time data through a ZigBee module. The receiver unit receives sensor data via ZigBee, processes it using an ATmega328 controller, and forwards the information to a NodeMCU module for IoT-based cloud communication, enabling remote monitoring through mobile or laptop interfaces. The system supports efficient energy utilization by prioritizing renewable energy usage, enabling intelligent load control, and providing real-time energy insights to users. Experimental results demonstrate reliable communication, accurate energy monitoring, and effective load management. The proposed architecture offers a low-cost, scalable, and energy-efficient solution suitable for smart homes and small-scale residential applications.

 Abstract

Investor behaviour in financial markets is often influenced by psychological traits and behavioural biases rather than purely rational considerations. Recognising the heterogeneity among investors is therefore essential for understanding investment decision-making. The present study aims to classify equity market investors into homogeneous groups based on personality traits, behavioural biases, investment performance, and repurchase intention using cluster analysis. Primary data were collected from 727 individual investors through a structured questionnaire. Hierarchical cluster analysis using Ward's method was first employed to determine the optimal number of clusters, followed by non-hierarchical K-means cluster analysis to form final clusters. The results reveal five distinct investor clusters, each exhibiting unique combinations of personality characteristics and behavioural biases. The clusters were validated using ANOVA, confirming significant differences across all clustering variables. The study develops meaningful investor typologies--Vulnerable Investors, Gregarious Investors, Achievement-Striven Investors, Adventurous Investors, and Modesty Investors--which provide valuable insights for financial advisors, policymakers, and investors in designing customised investment strategies and behavioural interventions.
