 Abstract

The paper investigate the role of STATCOM in power system network for enhancement of system stability and reduction of voltage as well as power fluctuations. The power system consists of 60MW wind farm (IG Based) connected to 132 KV Grid with the help of a transmission line and step up transformer. The wind speed variation causes power fluctuation subsequently voltage fluctuations. The MATLAB simulation result shows that STATCOM gives satisfactory result in the process of enhancement of power quality of the system.

 Abstract

The need to enhance the thermal performance of heat transfer equipment has driven the development and use of several heat transfer enhancement techniques. Wire-coil insert has been used as one of the passive heat transfer enhancement techniques and are the most widely used in heat transfer applications. The main objective of this work is to study the effect of wire-coil insert on the overall heat transfer rate and the pressure drop characteristics of the tube under constant wall temperature boundary condition. This work presents a numerical study on three wire coils of different pitch (P) (0.0225 m, 0.027 m and 0.03096 m and coil diameter 0.002 m) inserted in a smooth tube in laminar and turbulent regimes. A commercial CFD software tool has been used for this study. The friction factor and Nusselt number for water flowing through the specified pipe (internal diameter (D) = 0.018 m, specimen length = 0.080 m) were obtained first for the smooth pipe and then for the pipe with a wire coil insert in the Reynolds number range of 350 to 4900 and Prandtl number of 6.99. The Nusselt number and friction factor of various insert geometries are higher than that of plain tube. The Nusselt number increases with the rise of Reynolds number and the reduction of pitch of the insert. The friction factor decreases with the increase of Reynolds number. The increase in Nusselt number has been found to be of the order of 1.505 1.47 and 1.225 times with respect to the plain tube for wire coil pitch to diameter ratio of 1.25, 1.50 and 1.72 respectively.

 Abstract

Helical gears work quietly and smoothly under heavy loads. Their design optimization includes multiple objectives and large number of design variables. Thus, a reliable and robust optimization technique will be useful to achieve the optimal design solutions. The optimization of helical gear drive can be carried out using different non-conventional optimization techniques like genetic algorithm, particle swarm optimization and ant colony optimization, etc. In the present work, volume optimization of helical gear drive is carried out using genetic algorithm. Several factors for the strength and size based on DIN standards are considered from the literature. The formulation of multivariable, constrained non-linear optimization problem with derived objective function and constraints is presented. The volume minimization using genetic algorithm is performed in MATLAB and results obtained are found to be satisfactory.This optimum set of parameters is used for modeling of helical gear pair by CREO 4.0 Software Now import the helical gear pair for stress analysis by using ANSYS 16.2 software and find that the stress value is less than the permissible stress of case hardened steel.

 Abstract

Presently Information Communication Technology (ICT) acting as an important role in enhancing the quality of education and research. All types administrative and management activities of ICT are currently being popular in schools, colleges and in research Institute. ICT is an extensive term for Information Technology (IT) that provides information through telecommunication.The different electronic gadgets such as computer system/hand held system, audio video display and internet are being used for proper and smooth function of the system. Records of library system is indicating that searching of general materials such as books (Indian and foreign authors), papers and encyclopedia covered 37% and web page search indicated 33% and rest including journal, website and others through ICT. The result clearly indicating thatapplication of ICT is more intense in technical institute compare to the general degree colleges. Use of ICT in degree colleges are lagging by 20% as compare to technical institute in India. All the students as well as faculties put their opinion in favors that the ICT application in their institute are applicable for collection/sending academic materials when it needs. It also helps to enhance the performance of academic institute when teaching/learning was continued in online pattern. ICT provide its service through CD, DVD, and others storage system to deliver materials from one to another. Basically, all types of online activities and functions are properly maintained through ICT application.

 Abstract

This paper examines the transformation of women's roles in the Indian family system from the reformist era (1857-1947) to the contemporary period (1947-2025), highlighting both continuity and change. It traces how reform movements, colonial legislation, and nationalist struggles redefined women's domestic and social positions, while Partition exposed their vulnerabilities within families. Post-independence, the Constitution and family laws--such as the Hindu Marriage Act (1955) and the Hindu Succession Amendment (2005)--expanded women's legal rights in marriage, inheritance, and protection from violence. National surveys like the National Family Health Survey (NFHS) and Periodic Labour Force Survey (PLFS) reveal significant progress: higher female literacy, greater participation in decision-making, delayed marriages, and economic contributions. Yet, persistent challenges--including dowry violence, unpaid care burdens, and son preference--underscore the resilience of patriarchal traditions. The study argues that the Indian family is not a static entity but a dynamic arena where women negotiate between empowerment and restriction, illustrating how legal reform, education, and cultural continuity collectively shape women's lived experiences across two centuries.

 Abstract

The rapid growth of the Internet of Things (IoT) has increased concerns regarding security, privacy, and cyberattacks. Traditional security mechanisms are often insufficient for modern IoT environments due to resource constraints, heterogeneous devices, and large-scale data generation. Deep learning techniques have emerged as effective solutions for intrusion detection, malware analysis, anomaly detection, and privacy preservation in IoT systems [7], [9]. This paper presents a comparative analysis of deep learning approaches for IoT security and privacy based on studies published up to 2021. Various IoT threats, security layers, deep learning models, and intrusion detection mechanisms are reviewed. The study also compares conventional machine learning approaches with deep learning-based methods and discusses challenges, future trends, and research opportunities.

 Abstract

The Constitution of India has ensured equal status to all i.e. not only between men and men, women and women, but also between men and women. But the basic question is that how far we have been able to achieve the objectives provided by the constitution. In view of this, an attempt has been made to acquaint the Indian women with the constitutional provisions relating to them, so that they can fight for the rightful cause or justice, it is clear that all the provisions of the constitution are applicable to both the persons, i.e. men and women. But there are some of the provisions which exclusively deals with the women only.
