Rayleigh bernard convection in couple stress fluid with maxwell cattaneo law
The onset of thermal instability in horizontal layers of fluid heated from below illustrates many physical and mathematical features of the general theory of hydrodynamic stability. The effect of non-Fourier heat transfer in couple stress in a Rayleigh Benard configuration is analyzed theoretically in this thesis. Broad range of applications of couple stress fluid and the need for its characterization at a relatively small scale of time and length act as a motivation for the study of buoyancy driven convection in such fluids under the influence of magnetic field and under various modulations such as temperature, gravity, rotation and magnetic field by employing Maxwell Cattaneo law. newlineLinear and non linear magneto convection in couple stress fluid with Maxwell Cattaneo law newlineThe interesting facets brought about by the interactions between convection and magnetic fields in a Rayleigh Benard configuration for free free boundaries are analyzed in this chapter. Linear and weakly non linear stability analysis are carried out to study the system. It is proved that the oscillatory mode is not the preferred mode of instability. The couple stresses in the fluid and magnetic field are found to enhance the stability of the system whereas non-Fourier effects destabilized the system. newlineEffect of temperature modulation on the onset of Rayleigh Benard convection in a couple stress fluid with Maxwell Cattaneo law newlineThe effect of externally imposed time-periodic boundary temperature on the setting in of convection is examined using linear stability analysis. The Venezian approach is applied to deduce the critical Rayleigh number and critical wave number. The stability of the system is characterized by a correction Rayleigh number and is obtained as a function of the Cattaneo number couple stress parameter Prandtl number and the frequency of modulation. The study analyzes three types of temperature modulations viz. in phase, out of phase and only lower wall modulation. -

The Changing Trends in International Education in India: A review
The demand for international exposure and education is skyrocketing in India, mainly due to demographic changes, growth in IT, media exposure, broadening of career prospects, global opportunities, cultural exposure, adaptability, and the need for problem-solving skills in multicultural, global industries. Higher Educational Institutions (HEIs) are also responsible for providing an opportunity to equip students to be successful in complex, global work settings through integrating international perspectives in education. The paper aims to study and understand the trends among the inbound and outbound students in Indian HEIs in the past few decades. The pandemic has affected both kinds. Above all, the new National Education Policy (NEP 2020) focuses on the attainment of global standards for Indian HEIs and attempts to attract more inbound international students to Indian HEIs. The chapter explores the internationalisation trends India has experienced and will also share the prospective trends in higher education's internationalisation in India based on the new National Education Policy 2020. 2025 selection and editorial matter, Kennedy Andrew Thomas, Joseph Chacko Chennattuserry and Joseph Varghese Kureethara; individual chapters, the contributors. -
Vanet Framework for Optimal Target Selection in Handoff using machine Learning
The impact of mobile networking has been far-reaching and has transformed many technologies for the better. Among the more pioneering technologies of recent times, autonomous vehicles (AV) are being touted as the future of transportation. AVs are featured prominently due to their ability to provide services across the implementations concerning smart-city applications. Since the newlinenodes (AV) involved are highly mobile, it is important to keep the device connected and adapt the dynamic topology change. The network should be capable of switching AV between access points (AP s) dynamic and must take place without much delay. Handoff is the process where a node switches between APs depending on the changes in the network topology. Various studies have claims that the use of Machine Learning or Deep Learning improves the efficiency of decision making in mobile networks. In this research work a dynamic handoff framework, inspired by the traditional Indian game of Kho-Kho is proposed. It selects the most optimal AP for newlinecommunication in a mobile environment. Initially the nodes within an AP are newlinecategorized as sticking and steering nodes. Identifying the nodes list for executing newlinethe Kho-Kho based handoff for the steering nodes. The framework makes use of Artificial Neural Networks (ANN) to perform the operation of handoff and selects the most optimal AP once the handoff trigger occurs. ANN is designed for multiple parameters, including signal strength, noise, and direction to make its decisions regarding handoff. The proposed Kho-Kho model has been newlineimplemented and analyzed using the NS3 simulator. Simulation results have indicated a higher performance of the proposed Kho-Kho approach when compared to the existing standard implemented for vehicular ad hoc newlinecommunications in IEEE -

WATCHING AND BEING WATCHED: POWER, SURVEILLANCE AND AGENCY WITHIN THE DEVADASI SYSTEM
This article explores the devadasi system in India through the dual thoughts of Michael Foucaults Panopticism and Agency Theory, examining how power dynamics and social control mechanisms were both enforced and resisted. The devadasi system, originally a revered religious practice, evolved into a complex structure of exploitation and marginalization, where women dedicated to temple service were subjected to pervasive surveillance and disciplinary practices. By applying Panopticism, this study reveals how the British administrators and the nationalists maintained strict control over devadasis, ensuring their subjugation within the social hierarchy. Simultaneously, Agency Theory illuminates how devadasis challenged these oppressive structures, asserting their autonomy in subtle but significant ways. This analysis not only deepens our understanding of the devadasi system but also contributes to broader discussions on the intersections of power, control and agency in marginalized communities. The study also highlights the importance of examining historical systems of oppression through critical and theoretical frameworks to uncover both the mechanisms of control and the resilience of those subjected to them. 2025 Journal of Dharma: Dharmaram Journal of Religions and Philosophies (DVK, Bangalore), ISSN: 0253-7222. -

Surveilling bodies, governing morality: Biopower and the contagious diseases acts in colonial India
This article explores the Contagious Diseases Acts (CD Acts) in colonial India using Michel Foucault's theory of biopower, focusing on their impact on devadasis. The Acts subjected women's bodies to medical and legal scrutiny, pathologizing female sexuality while reinforcing patriarchal and caste hierarchies. Devadasis, historically associated with temple practices, were recast as vectors of disease and moral disorder, aligning with the colonial administration's broader project of governance through regulation and surveillance. This study examines how the CD Acts functioned as a technology of power, reshaping devadasis identities and controlling their bodies to sustain social and political order. It also investigates how these mechanisms were challenged by resistance, demonstrating the adaptive and contested nature of colonial power. By situating the devadasis within the framework of biopower, this analysis illuminates the intersection of health policies, sexuality, and governance in shaping colonial hierarchies and marginalizing vulnerable communities. 2025 Elsevier Masson SAS -
Role of media in social issues: Media coverage of Vidarbha mass suicide by print media /
Media has always been an influential medium. It also has the biggest power to make aware of the people and the government. Thus it makes the government aware about the common people‟s problems and needs and making them act accordingly. In fact, it‟s actually the duty of the media. It‟s better to say that its function is nothing but to be a „watchdog‟. There are 4 theories of press/media and three other theories which are called „Development or Alternate Theories‟. -

A Study on Impact of Dopants on Piezoelectric Parameters of Aluminium Nitride
Doping is a critical in piezoelectric base materials used as sensors or energy harvesters. It has a significant effect in determining the output parameters of an energy harvester. This paper studies the effect and impact on piezoelectric properties when materials are co doped and singly doped by considering some common dopants found in the literature. From the study, the elastic constant and c/a ratio are found to be decreasing and all other lattice parameters such as piezoelectric stress coefficient, electromechanical coupling constant, Born effective charge etc. are increasing, although some discrepancies are there. Scandium, magnesium, Lithium and its co-dopants are mainly considered for the study. Another factor that should be considered is doping concentration. Excessive doping with scandium (Sc) has been demonstrated to reduce the coercive field (Ec), enabling ferroelectric switching in AlScN thin films. The critical factor for achieving ferroelectric switching lies in sufficiently lowering the energy barrier between the two polarization states made of the wurtzite structure. This can be accomplished either by increasing the proportion of the non-Group-III metal or through strain engineering.

Improved piezoelectric energy harvester design using aluminum nitride for improved voltage and power output
This research focuses on improving the performance of piezoelectric energy harvesters (PEHs), which convert ambient kinetic energy into electricity. One of the primary challenges with piezoelectric harvesters is their high resonant frequencies, which often do not align with the lower natural frequencies of ambient vibrations, limiting their efficiency. The goal of this research is to propose a new technique to optimize the design of PEHs, enhancing voltage output and power conversion efficiency. The proposed method combines an Arithmetic Optimization Algorithm to optimize the harvesters dimensions with a Dual Temporal Gated Multi-Graph Convolution Network (DTGMGCN) to forecast resonant frequency and harvested voltage. The principal objective is to reduce resonant frequency errors and enhance energy conversion efficiency. The results, implemented on a MATLAB platform, demonstrate that the proposed method outperforms the existing techniques, such as robust chaotic Harris Hawk optimization, K-Nearest Neighbor Algorithm, and Heaviside Penalization of Discrete Material Optimization. The existing techniques show errors of 0.04%, 0.06%, and 0.08%, while the proposed method achieves an error of only 0.02%. Additionally, in terms of efficiency, the proposed method reaches 98%, significantly higher than the 65%, 78%, and 85% achieved by the existing techniques. These findings indicate the efficiency of the proposed approach in improving the design and performance of piezoelectric energy harvesters, offering a promising solution for more efficient energy harvesting systems.
