IMG Seminar: An Input-powered AC/DC Converter with Zero Standby Power for Energy Harvesting Applications

Event date: 
Wed, 09/01/2010 - 7:00pm to 7:30pm

Energy harvesting techniques require more reliable power electronics. Conventional AC/DC converters in energy harvesting systems are normally self-powered by their load-sided energy storage elements. This feature makes the storage elements easily drained and the whole system may no longer be able to function. An input-powered AC/DC converter is proposed to eliminate the need for pre-charging the load and allows for infinitely long intervals from the energy harvester.

Note: Drinks and snacks will be served for Fall lMG seminars.

PIRE: Collaborations with France and Japan on Multiphase Fluid Science and Technologies

Professors Lou Cattafesta (IMG), Ranga Narayanan, and Jason Butler of the University of Florida have been selected to lead an NSF Partnership for International Research and Education (PIRE) project focusing on the research of multi-phase flows with technological applications. Two US universities (The University of Florida and Florida State University) will work in collaboration with five French and five Japanese institutions to carry out this research. More information about this new and exciting project partnership can be found here. Congratulations, Dr. Cattafesta!

UF Researchers to be Involved in the FAA's Center of Excellence for Commercial Space Transportation

The Federal Aviation Administration (FAA) has selected New Mexico State University (NMSU) to lead a partnership of colleges and universities throughout the country in its new Air Transportation Center of Excellence for Commercial Space Transportation. The FAA press release describes the center as being a "partnership of academia, industry, and government, developed for the purpose of creating a world-class consortium that will address current and future challenges for commercial space transportation."

Dr. Lou Cattafesta of IMG is leading UF’s participation in this research endeavor as part of the Florida Center for Advanced Aero-Propulsion (FCAAP), one of the institutions participating in this partnership. The FCAAP team, led by Farrukh Alvi at FSU, includes researchers from UF, FSU, UCF, and FIT. The FAA press release can be found here

Chris Meyer wins "Professional Excellence" Award

Chris Meyer has been selected by the UF College of Engineering as the 2010-2011 Ph.D. recipient of the Attributes of a Gator Engineer Recognition Award for Professional Excellence.  He was selected for "exemplifying the attribute of professional excellence with his strong record of character and performance."  Chris will be recognized by Dean Abernathy in an awards ceremony in August.

IMG Seminar: Overview of Micropillar Shear Stress Sensors

Event date: 
Fri, 08/13/2010 - 3:30pm to 4:00pm

This Friday, Jessica Sockwell will be giving a seminar on micropillar shear stress sensors. Micropillar shear stress sensors have been developed in recent years with the goal of attaining full-field shear stress measurements within turbulent boundary layers. This talk will explain how the sensors work, summarize the design and fabrication of these devices, highlight their strengths and weaknesses, and discuss how these sensors might be further improved for future use.

IMG Picosecond Laser Micromachining Workstation Online

Installation of an Oxford Lasers J-355PS Laser Micromachining Workstation has just been completed and the system is ready for use.  The tool is the first of its kind to be installed in the U.S., and provides a unique capability for IMG by enabling the machining of many different types of materials including sapphire and silicon, as well as other glasses and polymers. Purchase of this system was made possible by collaboration between Professors David Arnold and Mark Sheplak of IMG and Professor Tony Schmitz of UF's Machine Tool Research Center (MTRC).
