What is a Geologist?
Dr. Genet Duke, Assistant Professor of Geology (Arkansas Tech University)
Dr. Genet Duke received her PhD in 2005 after 26 years of working as a geologist in both industry and academics. She was a full-time professor of Geology at two other universities before arriving at Tech. These include Louisiana State University at Alexandria and Northeastern Illinois University in Chicago. Her first job in 1979 was exploring for uranium in Alaska, but over the years she has also explored for gold, diamonds, and petroleum. She has worked in geochemistry labs and run large instruments such as XRD, electron microprobe, SEM, and various mass spectrometers. Her geologic studies and work have taken her to Guatemala, Nicaragua, Alaska, Canada, Wyoming, Montana, Utah, South Dakota, New Hampshire, and Colorado. Her expertise is in the area of mantle-derived igneous rocks, and her current research includes Crater-of-Diamonds in Arkansas, as well as the Magnet Cove carbonatite rocks east of Hot Springs, Arkansas.
Dr. Duke will give a presentation entitled "What is a Geologist?" Dr. Duke will discuss the extraordinary variety of careers in geology, provide personal experiences, and discuss exciting opportunities for future geoscientists.

This presentation shows you how a power system is operated and controlled using graphic-based power system simulators, PowerWorld, and EMTDC-PSCAD. The usage of both types of software will be helpful for students who have more interest in power system topics by obtaining a sense of what's happening in a power system.
Dr. Carlos L. Castillo, Assistant Professor of Electrical Engineering (Arkansas Tech
Mr. Drew Mangus, Graduate Assistant (Arkansas Tech University)
Autonomous mobile robots are currently being used in many different fields: current applications include military aerial surveillance and manufacturing . Some of the basic concepts and algorithms used in this field will be presented.
Mr. Stan Apple, Instructor of Mechanical Engineering (Arkansas Tech University)
The scanning electron microscope is one of the most versatile instruments available for the examination and analysis of the microstructure of solid objects. In addition, it can be used to examine and analyze biological samples. A 1018 oven-cooled, heat-treated steel sample showing iron carbide regions in a ferrite matrix will be viewed. In addition, a biological specimen will be coated with gold and viewed with the microscope.
Dr. John Krohn, Professor of Mechanical Engineering (Arkansas Tech University)
Many everyday objects emit small amounts of radiation. In this exercise, students will get a chance to see some common radiation detection/counting equipment, determine whether common objects emit detectable amounts of radiation and examine other aspects of radiation encountered in daily life.
Dr. Wayne Helmer, Professor of Mechanical Engineering (Arkansas Tech University)
