Foss Big Data Storage Solution, Nurdeen Salami Aug 2014

Foss Big Data Storage Solution, Nurdeen Salami

STAR (STEM Teacher and Researcher) Presentations

NASA projects require a reliable approach to store large volumes of data. Accordingly, it is crucial to adopt a lightweight, reliable, and scalable database. Current NASA databases bear costly license fees with undesirable speed and flexibility. The purpose of utilizing the AERO Institute as an IT test bed, or “Sandbox,” is to design, build, test, and implement software solutions prior to transfer to NASA projects. Cassandra coupled with the Astyanax API is a viable solution for storing big data. Store a minimum of 2GB of C-FOSS data in multiple file formats (.csv, .log, .xml, and .jpg). Use benchmark tests to ...

Computer Engineering

A proof of concerpt for data transmission using light as a medium. Data is transferred by strobing and LED faster than the human eye can detect in an attempt to come up with a more secure alternate to in-building wifi.


Wireless Ad Hoc Networks For Mobile Devices Via High Frequency Sound Waves, Yashar Bahman Jun 2012

Wireless Ad Hoc Networks For Mobile Devices Via High Frequency Sound Waves, Yashar Bahman

Computer Engineering

The purpose of this research it to give mobile phones the ability to create a cross-platfor wireless ad-hoc network. To accomplish this the phone’s speaker/microphone will be treated as a modulator/demodulator (or modem for short). The idea is that the phone will generate sine waves at various frequencies to output them on the speaker on one end and also record audio with the microphone to analyze and decode it into data on the other.

Once complete, these functionalities will all be rolled up into one easy to use library named Wave, which can be used to send ...
