Change-Impact Analysis For Android Applications

Team Members: Jefferson Ridgeway, Darren Hui

Summer 2015

Mentor:Dr. Guowei Yang

Keywords- Android, regression testing, Android Library

Android is a widely used mobile platform for which many applications are developed. During the development process, many modifications are made resulting in potential changes in old behaviors and the introduction of new behaviors. Therefore, ensuring the reliability of applications is highly desirable. However, traditional regression testing techniques cannot be directly applied to the Android domain due to its differing architecture. To better understand how to develop and improve upon regression testing techniques, we first conducted a bug study focusing on bugs related to change. Then, we performed a change impact analysis on selected applications to understand the potential effect changes in the Android library and in the Activity component could have on the rest of the application. We believe that this study will help developing new or improving upon existing regression testing techniques specific to the Android domain.

Documentation of Site Preparation for Installation of SeaSpace Ground Stations at ECSU

Team Members: Jefferson Ridgeway, Tori Wilbon, Nigel Pugh

Spring 2015

Mentors: Andrew Brumfield, Michael Osterhouse

Keywords- SeaSpace, TREX, TeraScan, CentOS, Visualization Stations, TeraVault, Monitoring Systems, GOES

In September 2014, a transition was made to a direct purchase and installation of Seaspace hardware and software. The installation of the Seaspace hardware included: 15 Visualization stations, 2 monitoring systems, a Teravault raw storage device, and a TeraScan Rapid Environmental X-treme (TREX) high-powered processor. The installation of the Seaspace software on the 15 Visualization stations included: an updated version of TeraScan, which includes the Graphical User Interfaces TeraVision and TeraMaster, and CentOs, which is a Linux-based Operating System. Also two 5.0m L band systems were installed on Dixon-Patterson hall in the summer of 2012. The purpose of this project was to document the installation requirements and internal processes at ECSU for Seaspace Hardware and Software Equipment, with also addressing; the location of engineering findings, location of installation requirements, repositioning and securing current ground stations, and proper training center needs.

A Project Management Framework for Cloud and HPC Resource Providers

Team Members: Jefferson Ridgeway, Ifeanyi Rowland Onyenweaku

Summer 2014

Project Leaders: Gregor von Laszewski, Fugang Wang

Keywords- Cloudmesh, Project Management, User Management, Project Review Management, FutureGrid, MongoDB, Django

Cloudmesh is a project that allows the management of virtual machines in a federated fashion. It can be run in two modes. One is a standalone mode where the users run cloudmesh on the local machines. The second mode is a hosted mode where multiple users share a web server through which the virtual machines are managed. One of the important functions for cloudmesh is to provide a sophisticated user management. This user management is currently conducted in drupal through the FutureGrid portal via an integration to the FutureGrid LDAP server. However, as the rest of cloudmesh is developed in python, the user management in FutureGrid has had some limitations. It is important to identify a python based solution with more advanced features in order to re-implement the user management functionality in cloudmesh to address long term sustainability of the user management component.

This research will explore how to design a data model in python via mongoengine to represent users and user created projects to identify how we can leverage either django or flask to manage such created projects. To address the later, we will first evaluate if we can get a django web application started and identify how to use it. If this turns out to be too difficult, we will fall back to flask. As part of the management, we need to implement a queue in which users are queued for approval, and a project queue whereby projects are queued and approved by a committee. A simple backend system written in python will support this task and provide an abstraction that is outside the web interface.

Update of the CERSER TeraScan Cataloguing System TeraScan Image Processing Scripts

Team Members: Derek Morris Jr., Jefferson Ridgeway, Tori Wilbon

Spring 2014

Mentor: Jeff Wood

Keywords- GOES, TeraScan, ImageMagick, Macintosh OSX, MySQL, PHP, Remote Sensing

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 data from orbiting National Oceanic and Atmospheric Administration (NOAA) Polar Operational Environmental Satellites (POES) and the Geostationary Operational Environmental Satellites (GOES). This data is collected by SeaSpace TeraScan systems installed in the CERSER labs in Dixon-Patterson Hall.

In 2005, the processing system underwent a major update due to a migration to a new operating system. A minor update was needed at this time to deal with a second operating system migration and display of the processed images on the CERSER web site. Since then, a second transfer to a new server was made in 2013. The cataloguing system went down at this time and was not repaired due to technical issues with the TeraScan system. The 2014 team corrected issues within the current server directory system and updated the data script to process images from the GOES-13 satellite received by the TeraScan system. Software and languages utilized for this task included ImageMagick, PHP, HTML, Dreamweaver, phpMyAdmin, and MySQL.

Along with this operating system update, a major script development was needed on the TeraScan processing equipment due to an upgrade in hardware. The ground station upgrades included a 3.7m X/L band, a 3.6m C band, and a 5.0m L band dishes, along with accompanying computing hardware. This new script processes both infrared and visible light images received from the GOES-13 satellite into the Tagged Image File (TIFF) Format.

Analyzing Charles's Law and Avogadro's Law

Team Members: Brianna Williams, Bria Lynch

Summer 2013

Mentor: Mrs. Shanta Outlaw

Keywords- Hydrogen gas, Anodes, Cathodes, Hydrogen Fuel Cell Vehicles

Abstract
In Chemistry, there are four main gas laws that are discussed to understand how and why gas particles function. The four main gas laws that are present in the field of Chemistry are as follows: Charles's Law, Gay-Lussac's Law, Boyle's Law, and Avogadro's Law. Each of these laws has their own distinct way operating but is always in the world surrounding us. Two laws in particular Charles's Law and Avogadro's Law, are being focused on for this experiment. The purpose of this experiment is to prove Charles's Law and Avogadro's Law through a series of experiments
and of analyzing of the data. After proving the two gas laws and viewing the data, it is important to figure out how the two have a relationship with Hydrogen fuel cll vehicles and how it works. Future work includes implementing Hydrogen fuel cell vehicles to maintenance at Elizabeth City State University in order to reduce the carbon footprint (the amoun of Carbon dioxide that an individual or organizaztion emits into the atmosphere) of the school.
