SIAM SEAS 2014


38th Annual SIAM Southeastern Atlantic Section Conference

March 29-30 2014

Florida Institute of Technology

Melbourne, Florida

 

The 38th annual meeting of the SIAM Southeastern Atlantic Section was be hosted by the Florida Institute of Technology in Melbourne, Florida, March 29-30, 2014. SIAM, Embry-Riddle Student Chapter members participated in the plenary lectures, mini-symposia, and presented two posters.

 

Poster 1: MODELING MARINE NAVIGATION USING AUTONOMOUS UNDERWATER VEHICLES

Presented by:  Zakaria Daud, Dynamite Obinna, James Pam

Abstract:

The buoy system is the gateway to maintaining communication with the Eco-Dolphins. The Eco-Dolphin fleet of Autonomous Underwater Vehicles (AUVs) utilizes underwater wireless sonar networking approach. The sonar transducers within the fleet specify their current location, and the hydrophones relay specific location to the ground station. The system provides location information of AUVs underwater using sonar triangulation with marginally low error. The team is working on software to send specific coordinates to the dolphin and calculating the most efficient path to travel underwater from data provided by sensors.

 

Poster 2: COOPERATIVE FLEET OF AUTONOMUOS UNDERWATER VEHICLES

Presented by: Junzhen Shao, Ci Wen, and Jonathan Jaworski

Abrstract:

The progressive development of a cooperative fleet of three autonomous underwater vehicles for research and education, which can maintain ecological balance. The multidisciplinary development incorporates mathematical modeling in the design and testing of integrated systems. The team’s background in Arts and Engineering science provides the innovation required to fulfill this multitask mission.

The design begins with a one foot by four foot streamlined elliptical body resembling the Dolphins. The material science investigation led the development of the Eco structure that incorporates recycled fiberglass boat materials. The thermoset materials provide the high strength to weight ratio required.

The complexity in developing the algorithm for three underwater vehicles begins at the surface level. When the fleet is surfaced they are able to relay all data acquired from missions via wireless communication channels. While the fleet performs submerged missions small data files can be sent over sonar links for trajectory mapping procedures. The Eco-Dolphin is a platform that has the ability to configure multiple sensors configuration to acquire data on a as need basis.
