A Comparison of Job Duration Utilizing High Performance Computing on a Distributed Grid
Mentor: Mr. Jeff Wood


The Center of Excellence in Remote Sensing Education and Research (CERSER) on the campus of Elizabeth City State University is currently tasked with the responsibility of receiving remotely sensed Advanced Very High Resolution Radiometer (AVHRR) data from orbiting National Oceanic and Atmospheric Administration (NOAA) satellites. This data is collected by the SeaSpace TeraScan® system installed in the CERSER labs in Dixon-Patterson Hall.
When this system was initially installed in 2005, the data was collected, processed, annotated, and transformed into images in the Tagged Image File Format (tiff) on a Windows® based server. These tiff images were then uploaded to the CERSER archive library server located at http://cerser.ecsu.edu. Once uploaded, they were converted into various resolutions and their information was added to a tracking database maintained with Microsoft Access software. This database provided a searchable means for retrieving satellite image data through various parameters.
Since that time the CERSER server has been replaced with a Macintosh based server which cannot interact with the Microsoft based database and the Visual Based Scripting language. The goal of this project was to redesign the database and the code required to process the images. PHP, Structured Query Language, and Command Line instructions to the software package ImageMagick® were utilized to complete these tasks.

Analyzing MapReduce Frameworks Hadoop and Twister
Mentors: Thilina Gunarathne, Stephen Tak-Lon Wu, Bingjing Zhang


The primary focus of this research project was to analyze the attributes of MapReduce frameworks for data intensive computing and to compare two different MapReduce frameworks, Hadoop and Twister. MapReduce is a data processing framework that allows developers to write applications that can process large sets of data in a timely manner with the use of distributed computing resources. One of it's main features is the ability to partition a large computation in to a set of discrete tasks to enable of parallel processing of the computation. Google, the most popular search Engine on the internet, uses MapReduce to simplify data processing on it's large clusters. We analyze the performance of Hadoop and Twister using the WordCount application and compare the scalability and efficiency of the two frameworks for this particular application.

The Use of Math Sprint in a Tutorial Program for Seventh Grade Students to Improve End of Grade Test Scores
Mentor: Dr. Darnell Johnson & Cedric Hall


A "Math Sprint tutorial model" was used to improve the End of Grade (EOG) test scores on seventh grade students at Elizabeth City Middle School in Elizabeth City, North Carolina. This unique learning technique, developed at Elizabeth City State University, was used during a four-week study group composed of seventh grade students to enhance EOG test scores. The pre-test questions covered topics from the "North Carolina Mathematics Standard Course of Study" which consisted of five competencies: number and operations, measurement, geometry, algebra, and data analysis and probability. The North Carolina Mathematics Standard Course of Study is based on a philosophy of teaching and learning mathematics that is consistent with the current research, exemplary practices, and national standards. A diagnostic exam, corrective instruction, Math Sprints, and a post test were used to assist students with understanding of seventh grade math. The results of the pre and post exams showed student improvement in understanding seventh grade math.

Analyzing Long-term Summer Drought Effects on Temperature and Vegetation Using Aqua-1 Satellite Data
Mentor: Mr. Eric Baptise & Mr. Je'Aime Powell


According to the State Climate Office of North Carolina, since 2007 the northern coastal plain of North Carolina has been experiencing a long-term summer drought. The primary goal of this research was to find a correlation between land surface temperature and vegetation due to long-term drought using satellite data. The team collected imagery data through the SeaSpace TeraScan system in order to produce land surface temperature and normalized difference vegetation index products. The data products were averaged into monthly and yearly composites so that the team could use TeraVision to depict the differences of values for the products.
