Extreme Infrasound Seminar – Sept 8th at 5:30PM LSC 168
The Society of Physics Students is hosting their first Google Hangout seminar of this academic year on the topic of infrasound.The seminar will be in LSC 168 starting at 5:30PM on Tuesday, Sept 8th.
You can watch the live-stream via YouTube: http://www.youtube.com/watch?v=tswEWuairYs
Infrasound is low-frequency atmospheric sound generally below the threshold of human hearing. Routinely produced by large-scale unsteady fluid flow, infrasounds can propagate for thousands of kilometers and can provide early warning of natural or man-made hazards. However, these signals are imbedded in a rich ambient sound field and their detection often relies on the processing of four or more microphones arranged as an array.This presentation discusses infrasound from extreme events, which produce very deep sounds. At the lower frequencies (mHz) radiated by the 2004 Sumatra and 2011 Tohoku tsunamigenic earthquakes, the 2013 Chelyabinsk meteor, and the 2014 Kelut volcanic eruption, the whole Earth vibrates. Large volcanic eruptions produce a long-ranging, recognizable acoustic signature that can be used for early warning of eruptions that pose an ash hazard to aircraft. At higher infrasonic frequencies, the ocean also radiates persistently in the 0.1-5 Hz range, and can provide supplementary observations of marine storminess and high surf.Anybody with an iPhone, Pod Touch, or iPad running iOS 7 or later can now record and process infrasound by downloading the free Infrasound Recorder and Analyzer apps from the Apple App Store.
Dr. Garcés specializes in large things that blow up. Specifically, the study of global infrasound from man-made and geophysical sources in the atmosphere, ocean, and solid Earth. He founded the Infrasound Laboratory of the University of Hawaii, and is a collaborating scientist with the Earth Observatory of Singapore. Dr. Garcés operates International Monitoring System stations in Hawaii and Palau, as well as regional stations in Hawaii. Recent projects include the study of infrasound from hurricanes, tsunamis, meteors, and high surf, as well as real-time acoustic monitoring of volcanic eruptions. Lately, he’s been going off the deep end while exploring the transition between gravity and acoustic waves.

UCA Google Hangout Seminar Series Featured in SPS Observer
The summer edition of the SPS Observer includes an article on the UCA Google Hangout Seminar Series. This series of seminars has been organized and championed by Dr. William Slaton. Over the last two years more than 20 speakers, from as far away as Australia, have given live presentations of their research to UCA students and faculty. The topics of these presentations range from the physics of bacteria to cosmic background radiation. Each of the presentations is available on YouTube and you can receive updates by following the twitter hashtag #GHOSeminar.
The schedule for future seminars is at http://faculty.uca.edu/wvslaton/GHOSeminar.html.

Computer Coding 2015 @ UCA for middle and high school students is a summer program sponsored by the Department ofMathematics, Department of Computer Science, and STEM Institute at UCA.
The goal of this program is to provide kids with an early opportunity to learn computer programming. The students will be taught basic programming concepts, various simple computing techniques and problem solving skills with some hands-on project work. “Scratch” and/or on-line resources will be introduced so students can practice and work on their projects. Students will learn important basic mathematical and computer concepts that improve their creative thinking, logical reasoning, problem solving, and team collaboration skills.
The program will be conducted by Mr. Sudheer Kavi, a Senior Solutions Developer at Acxiom and an adjunct professor of Computer Science at UCA.
When: June 9-July 3, 2015
Where: Math and Computer Science Building, UCA Campus
Cost: $75 per student

Kudos to Steve O’Connell and the Environmental Science and Geography students that have been working on the Conway Parks and Recreation Master Plan for the past year. There was a very positive article (for our College and UCA) on the front page of the April 15, 2015 Log Cabin Democrat. It mentioned two faculty and two groups of students from the CNSM being involved in the Parks Project.
This project is a good example of what geographers do at the cultural/economic end of our discipline. As Geography is the “new kid on the block” in our College, our discipline is sometimes still misunderstood, as it is with the general public. Once past grade school, we do not memorize capitals or locate countries on maps. We gather spatial data; in this case park location, size and type, sidewalk and bike access, demographic proximity and related factors. Then we analyze current and past use trends, but most importantly predict future use trends and options that might impact these trends.

Title: Image Stitching & Binarization
Date: Thursday, April 30th 2015
Time: 1:00 PM
Place: MCST 339
Image processing is any form of signal processing for which the input is an image, such as a
photograph or video frame. Our goal is to stitch various partial photos and make it look like a
single image without any overlapping. The project is primarily constitutes of three parts
including 2D image stitching, 3D image stitching and the image binarization techniques in order
to get good results from the degraded image.
Our primary goal is to build a 2D image of various buildings in the UCA campus. I actually
used a drone in order to capture these pictures for image stitching. A 2D image can be stitched
with ease because, there are various commercial and online software tools available to perform
the image stitching. However 3D image stitching is completely different from 2D image
stitching, because it needs various steps to be followed in order to create a 3D image. The
software’s provide the different editing options to edit the images after the stitching process is
done. But the image after it is stitched may contain some issues like the ghosting, parallax error
and overlapping. Once the image is stitched we can crop the portion of image which we require
for use. We were successful in building the various 2D images in the UCA campus as well as
the 3D images.
The last part of goal is to build an image that is crystal clear, because after the image is stitched
there may be some overlapping between the images. In order to overcome from some of these
issues we use a Image Binarization technique I was successful in building a clear image for the
degraded images which have text in it. All the concepts related to image processing research are
clearly explained in our documentation.
