Cplop - Cal Poly's Library Of Pyroprints, Kevin Webb

Computer Engineering

California Polytechnic Library of Pyroprints, CPLOP, is a web driven data-base application that stores data from the biology’s departments E. coli Pyrosequencing project. Some of this data was stored in Excel datasheets, while data from the pyrosequencing machines was stored as just a list of random .xml files. There was no useful way to organize and store the massive amounts of data from multiple file sources in one location, nor to perform the complicated searches and comparisons that the project requires. CPLOP’s primary goal is to store such data in three organized tables that relate to one another. It was …

Markerless Affine Region Tracking And Augmentation Using Mser And Sift, Gregory (Greg) Eddington Ii

Computer Engineering

Due to the advancements in mobile computing hardware and the inclusion of cameras in many computing platforms, augmented reality systems have become widely available. This paper presents a real-time implementation of a novel markerless augmented reality algorithm which is able to track two-dimensional affine regions without a priori information of the environment or computing a world model. The implementation consists of the MAR library; a modular software library which performs the region detection, identification, and tracking; and the Lighthouse application; a program which uses the MAR library to allow the user to augment scenes viewed from a camera. The algorithm …

Characterization Of A Dual Acoustic Receiver System For Measuring Range And Bearing To Acoustic Tags, Victoria Campana, Justin Knight

Computer Engineering

Experiements were performed to determine the effectiveness of the Lotek RT-A Hydrophone system and if it could provide the data necessary for a particle filter to determine the location of a shark. Over the period of a few months, we tested off the Cal Poly Pier at set GPS coordinates to characterize how accurately the Lotek System can determine range and orientation. Ranges from 0-500 meters were tested with the Lotek system being in a stationary position and Lotek receiver tag being put at specified GPS coordinates. The two hydrophone rigging was then rotated a full 360 degrees to gauge …

Streaming Client And Server Model, Austin Alan Diec

Computer Engineering

A few years ago, several Cal Poly undergraduates started the Autonomous Robot Platform (ARP). Interest in a revision of the ARP requires a new layer of communication. This paper describes the design and partial implementation of the communication layer to be used with the revised ARP. The communication layer would allow the autonomous robot platform to connect with a client over the wireless local area network (WLAN) for instructions and commands. It is important to note that currently, the assumed revision of the ARP is nonexistent, so many of the design decisions are based solely on the assumptions of ARP …

Detection Of Breathing And Infant Sleep Apnea, Brian Berg

Computer Engineering

Sleep apnea is a condition where people pause while breathing in their sleep; this can be of great concern for infants and premature babies. Current monitoring systems either require physical attachment to a user or may be unreliable. This project is meant to develop a device that can accurately detect breathing through sound and issue appropriate warnings upon its cessation. The device produced is meant to be a standalone device and thus was developed as an embedded systems project on a Xilinx Spartan 6 FPGA.

Reactive Routing In Hidra Networks, Scott Michael Marshall

Computer Engineering

In recent years, the Internet has grown so large that the future scalability of the Internet has become a major concern. The two primary scalability concerns are the size of the forwarding table and the ability for BGP to converge while distributing hundreds of thousands of routes.

HIDRA is a new Internet routing architecture that is backwards-compatible with existing routing technologies and protocols that focuses on feasibility-of-implementation. HIDRA remedies the first Internet scalability concern by proposing a means to reduce the number of entries in the default-free zone (DFZ) forwarding table.

This project extends HIDRA by designing a complete reactive …
