Date & Time: Thursday June 14, 2012 – 7:30 PM

Attention : The lecture building / room has changed.

Location: Montgomery Community College (Rockville Campus) – Campus Center Building (CC), Student Cafeteria Lounge (Get Directions, Campus Map )

Speaker: Jamal Rostami, PhD, PE

Synopsis:

This lecture will review various tunneling methods and will discuss the recent developments in the field of tunneling and related machinery. It will discuss applications of tunnels and underground excavation, various methods for tunneling, and will offer a brief review of the tunneling machines and achieved milestones in their size and performance. The lecture will discuss the sequential excavation methods used for many of the road tunnels around the world, mechanized tunneling in rock and soil, and will present brief video clip of some of the complex tunneling machines.

Lecture 49: Gravity and Dynamics of Motion in Orbit

Date & Time: Thursday May 10, 2012 – 7:30 PM

Location: Montgomery Community College (Rockville Campus) – Humanity Building (HU), Conference Room 009 (Get Directions, Campus Map )

Speaker: Mohsen Mosleh

Synopsis:

This lecture will entertain topics in “classical mechanics” which discusses the set of physical laws describing the motion of bodies under the action of applied forces. These physical laws provide extremely accurate results as long as the objects being considered are not macro-scale and the speeds involved do not approach the speed of light.

The selected topics in this lecture are gravity and its role on the dynamics of objects in orbit. The gravitational field is one the key fundamental interactions of nature which gives weight to the objects with mass and causes dispersed matter to coalesce, and coalesced matter to remain intact. It is also the driving force for objects under central-force motion in an orbit. The dynamics of motion in orbit with the Lagrangian perspective will be discussed. Examples of planetary orbits and their characteristics in the solar system will be presented.

About the Speaker:

Mohsen Mosleh is a Professor of mechanical engineering at Howard University in Washington DC and Past President of Iranian Academic and Professionals (IAAP). His professional appointments and services include Visiting Scientist at the Oak Ridge National Laboratory, Visiting Scientist at the Princeton Plasma Physics Laboratory, Guest Scientist at the National Institute of Standard and Technology (NIST), Advisory Board of the Mechanical Engineering Department at the University of Maine, Board of Directors of the American Society of Mechanical Engineers (ASME) of Washington DC section, Graduate Program Director at Howard University, Manager of MIT/Harvard-industry consortium on durability of total joint replacements at the Massachusetts institute of Technology (MIT).

He has been a reviewer for Maine Space Grant Consortium, Air Force Summer Faculty Fellowship Program (SFFP), National Science Foundation’s programs, American Society of Engineering Education and numerous scientific journals. He has also served as member of Technical Committee of professional conferences and meetings such as International Symposiums on Nano-manufacturing and Chair of ASME-STLE Conference sessions.

Dr. Mosleh received his Ph.D. in mechanical engineering from MIT. He earned his BS and MS degrees in mechanical Engineering from Amirkabir University of Technology. He has widely published peer-reviewed articles in scientific journals and proceedings. His research interests and activities include surface engineering, nanofluids, and nanocomposites. His teaching focus is on Classical Mechanics and Advanced Dynamics, Engineering Design, and Product Development. He has received numerous awards including Rabinowicz tribology award, ASME outstanding teaching award, distinguished faculty author award and Editor’s Choice paper award from TLT magazine.

Lecture 48: Global Water Challenges and Sustainable Solutions

Date & Time: Thursday April 12, 2012 – 7:30 PM

Location: Montgomery Community College (Rockville Campus) – Humanity Building (HU), Conference Room 009 ( Get Directions, Campus Map )

Speakers of this month: Drs Ben & Zohreh Movahed

Synopsis:

Water is life! After air, water is the most precious resource on earth. Without adequate and safe drinking water and proper sanitation, the whole society’s livelihood will be jeopardized. This presentation provides a brief overview of some of the local, national and global challenges related to water; presents many questions about the “current” practices related to water usage and discusses possible strategies towards sustainable solutions, including advanced water treatment and desalination as potential tools in the tool box. The audience will learn the value of water to life and the fact that, in the future, the most competitive world issue will be the availability of water, more than oil! The World Bank estimates that 1.1 billion people lack access to safe drinking water and about 50 percent of the world’s hospital beds are populated by people who have contracted water-borne diseases. The audience will also become familiar with some of the local and national challenges including: aging Infrastructure, consequences of large water main breaks (e.g., River Road Water Main Break); presence of micro pollutants in water supplies, concerns about the perception of “unacceptable” tap water quality resulting in excessive use of bottled water, the controversial idea of using of alternative non-potable sources for flushing toilets, and many more intriguing challenges.
