Lecture : 3 Year : II
Tutorial : 1 Part : II
Practical : 0
Course Objective
This course focuses on several branches of applied mathematics. The students
are exposed to complex variable theory and a study of the Fourier and
Z‐Transforms, topics of current importance in signal processing. The course
concludes with studies of the wave and heat equations in Cartesian and polar
coordinates.

Powerful Solar Storm to Doom 40 New Starlink Satellites - Here's Why That's A Problem.

Powerful Solar Storm to Doom 40 New Starlink Satellites - Here's Why That's A Problem. Imagine you've invested $12 billion in a new satellite system and you're about to launch 40 more satellites into space. But one day before the launch, a solar storm hits and fries all of your satellites. This is exactly what happened with SpaceX's Starlink project this morning. A powerful solar storm caused them to lose contact with their satellites just hours before they were set to be launched. Now, these satellites are going nowhere unless someone can figure out how to turn them on from afar or find a way to get them back into space before the sun has another solar storm. It's unclear if SpaceX will be able to fix this problem, but it's a good reminder that we need to protect ourselves from solar storms too...read on for why! What is a solar storm? A solar storm is an ejection of plasma and magnetic field from the sun. Solar storms happen when the sun's magn...

How to remove stress?

Got stress? 75% of adults are  reporting moderate to high levels of stress in the past month there has to be a solution So what are the best scientific methods to deal with stress and anxiety? How can you genuinely relax your mind and body? Normally people  says laughter is the best medicine but does it work out? It's also the stress medicine, when we laugh our oxygen intake increases stimulating the release of endorphins. Studies even show that simply waiting to see a funny movie can increase beta endorphin levels by 27% and Decrease stress hormone levels in the bloodstream.After a hilarious film, participants had lower levels of the stress hormone “Chromogranin A” in their saliva and while you're at the movies why not make out with someone, it decreases cortisol and increases Oxytocin from the pituitary gland in the brain creating feelings of attachment,bonding, Contentment and security, study participants who kissed their partners regularly over six weeks had lower ...
