We study dynamics of relativistic Coronal Mass Ejections (CMEs), from launching by shearing foot-points (either slowly - the ``Solar flare'' paradigm, or suddenly ``star quake" paradigm), to propagation in preceding magnetar wind. For slow shear, most energy injected into CME is first spent on work done breaking through over-laying magnetic field. At later stages, sufficiently powerful CMEs may experience ``detonation" and lead opening magnetosphere beyond some equipartition radius $r_{eq}$,...
In today’s rapidly evolving world, the demand for energy is steadily increasing, while need sustainability and efficient resource utilization becomes ever more critical. Smart Energy Management Systems (SEMS) are poised to play a pivotal role in addressing these challenges. Leveraging power of Machine Learning (ML), SEMS offer promising avenue optimize consumption, enhance grid reliability, reduce carbon footprints. This review article provides an in-depth exploration current state empowered...
Abstract Many explosive astrophysical events, like magnetars’ bursts and flares, are magnetically driven. We consider dynamics of such magnetic explosions—relativistic expansion highly magnetized overpressurized clouds. The corresponding qualitatively different from fluid explosions due to the topological constraint conservation flux. Using analytical, relativistic MHD as well force-free calculations, we find that creation a relativistically expanding, causally disconnected flow obeys...
The paper discusses the application of three well-known growth models, namelyexponential, logistic, and power to world literature in physics,chemistry, electrical & electronic engineering research, as reflected ininternational databases these fields from 1907 1994. growthmodels are classified characterised on basis two growth-rate functionsas suggested by Egghe Rao9. methodology Rao identifying a model has been reviewed with help casestudies major fields. results obtained through analysis...
Women constitute a high percentage of Science, Technology, Engineering, and Mathematics (STEM) graduates in India but this is not well reflected at the professional level. It believed that women face numerous challenges, affecting only their choice STEM as career also personal lives. Thus, it essential to understand underlying causes. The study aims explore hurdles faced by CSIR laboratories. A primary survey, using questionnaires, was conducted gain realistic holistic view experiences...

We find a class of twisted and differentially rotating neutron star magnetospheres that do not have light cylinder, generate no wind thus spin-down. The magnetosphere is composed embedded flux surfaces, with the angular velocity decreasing as $\Omega \propto 1/r$ (equivalently, becoming smaller at foot-points closer to axis rotation). For each given North-South self-similar twist profile there set profiles (limited from above) "smooth", dipolar-like magnetic field structure extending...
The progress of a nation is defined by the contribution all its citizens and role women in development cannot be undermined. Science technology (S&T) are key to nation's advancement. Thus S&T for can help wealth generation, improvement quality life real economic growth transformation any society. It well-known fact that proportion prominent Indian establishments universities low needs enhanced. Government India many non-government research bodies have been working on promoting...
Increasing oil prices have raised some serious global concerns. However, the fact remains that most solutions to tackle increasing trend in price of are controversial one way or another. Some popular often reduce greenhouse gases at expense pushing poorest deeper into poverty. It is therefore self-evident world needs find a middle path, harmonious balance between feeding millions and filling gas tanks order ensure stability for everyone. To achieve this, green fuel alternatives such as...
Most cement plants in India and around the world face a unique problem regards with power factor. In industries where their local generation Captive Power Plant (CPP) Waste Heat Recovery System (WHRS) is equal to or greater than plant's total utilization, load import from Grid brought down close zero. This done reduce cost because comparatively expensive. Though not required, connection mandatory for system floating mode ensure stability of system, avoid black-outs event CPP failures/trips...
