About Professor Yoginder Paul Chugh
“I have enjoyed the challenge to develop the youngest mining engineering department in the USA. Based on lot of unbiased self assessment over the years, I can say with lot of confidence that I have abilities to develop good organizations with strong foundations, and develop effective strategic plans based on input from different constituencies and my own assessment of the business environment. Organizational interests far precede my own interests and I do not give up that easily, and I love to nurture people to be successful. Just like any anyone else I also have my failings and the major one being that I do not have patience for incompetence.” (Chugh as he describes himself)
Research and scholarly work have been an integral part of my professional life, and it is something I truly enjoy. I have always enjoyed breadth in my scholarly work. My major scholarly contributions can be subdivided into four areas: Applied Rock Mechanics and Ground Control, Coal Combustion Byproducts Management, Dust Control in Coal Mining Face Areas & Mining Systems.
Professor Chugh has been actively involved in creating new knowledge to solve problems facing the discipline, mining industry, region and the country for ensuring that the created new knowledge is utilized in our industries in a timely fashion. He believes that Teaching, research, and scholarly activities have at least one thing in common—they change the way we think and do things.

Gap Sap With Pankaj Trivedi | Biker and Film Maker | S01E10 | Hindi

With over 15 years of experience in the training industry, conducting workshops for over 250 companies, it surprised most people when Pankaj decided to quit the corporate world and follow his heart to do what he loved the most - travel across the country on his bike, and seek adventures that stir his soul. And he got a lot more than what he expected.

Pankaj, a qualified expedition leader having graduated from the Himalayan Mountaineering Institute, has trekked some tough terrains, biked across various locales and lived in harsh conditions, just to fuel his passion for adventure. And somewhere along the way, as he met with people from different regions and cultures, he graduated from being a traveler to a story-seeker. His interactions with people gave him a good pulse on how they feel, what they go through, and somewhere deep down; he wanted to make a difference in their lives.

Pankaj at Rosehub's Office during his Varanasi stay.

So he packed his bags, set off on his bike armed with his cameras, raw talent and a heart of gold, in search of stories that needed a happier ending. Join the Journey of Doing Right and help us complete the stories we find along the way, with our Do Righter Pankaj Trivedi. (Quoted from:

Gap-Sap with | Prof. Kunal Karan | University of Calgary, Canada

We had a wonderful conversation with Prof. Kunal Karan; Department of Chemical and Petroleum Engineering, University of Calgary, Canada. He works in the field of alternative energy, specifically on ‘electrochemical’ energy conversion and storage technologies. He is internationally recognized for his notable contributions in the field of fuel cells, which is an energy conversion technology akin to batteries that produces electricity directly from fuels. He is author of over 100 peer-reviewed publications and has been invited to give research talks across the globe. At the University of Calgary, he co-founded and is also an Associate Director of the Calgary Advanced Energy Conversion and Storage Research – Technologies (CAESR-Tech) group. Prof. Kunal Karan spend his growing years in different states/cities in Eastern India. He obtained his undergraduate education in Chemical Engineering at IIT (BHU) and then moved to Canada for higher studies and work. follow this link to know more about him:

Abstract the Lecture
This Lecture will provide an overview of adaptive optics and its applications to imaging satellites, ground telescopes and laser systems. It will also provide an overview of research performed at NPS in Adaptive Optics Center of Excellence in these areas. NPS has Segmented Mirror Telescope (SMT) testbed.  SMT consists of 3 meter diameter space telescope with 6 segments. Each segment has 156 actuators for surface control and three fine and 6 coarse actua

tors for segment phasing. It has Shack-Hartmann wave front sensor for surface control and phase diversity sensor for segment phasing. It also has Fast Steering Mirror for jitter control. These mirrors need to have very fine surface accuracy in the range of 30 nm RMS.  Research is also performed on reducing primary mirror surface performance requirements by adding a deformable mirror in the optical path. Another area of research is correcting laser beam aberration due to atmosphere turbulence by using adaptive optics. Applications are laser communications and high energy lasers.
