The automatic prediction of protein three-dimensional structures from an amino acid sequence has become one of the most important and researched fields in bioinformatics. As models are not experimental structures determined with known accuracy but rather with prediction\, it is vital to determine estimates of a model'\;s quality. \; We attempt to solve this problem using machine learning techniques and information from both the sequence and structure of the protein.

In this dissertation\, we study data collection and its achievable network capacity in large-scale Wireless Sensor Networks (WSNs). Firstly\, we investigate the data collection issue in dual-radio multi-channel WSNs under the protocol interference model. We propose a multi-path scheduling algorithm for snapshot data collection in single-radio multi-channel WSNs and derive its network capacity\, which is proven to have a tighter bound compared with the existing best result. We subsequently propose a novel continuous data collection algorithm for dual-radio multi-channel WSNs.

In the field of neuroscience\, it is important to share knowledge of identified neurons among neuroscientists. This project presents a cloud-based collaborative platform for neuroscientists to browse and edit information about identified neurons online. NeuronViz is an ongoing effort that builds on the NeuronBank project\, which was started several years ago by a group of faculty members and students from Computer Science and the Neuroscience Institute.

Community resources play an important role in the daily lives of people living in the low-income neighborhoods of Atlanta. These resources include health care\, child care\, literacy training\, education\, welfare\, social services\, transportation\, housing and neighborhood improvement\, public safety\, crime prevention and control\, recreation\, rural development\, and community improvement. The Public Health Institute at Georgia State University has developed a comprehensive guide of inner-city community resources.

The scope of the project is to visualize 3D surface tomography data obtained from volcano-affected areas. An Android application has been created that loads tomography data of a specific format from the SD card of mobile phones running Android. A 3D surface plot is built from the data.

In the past decade\, natural language processing applications have become part of our everyday experience\, from spell and grammar checking in word processors to machine translation on the web\, from email spam detection to automatic question answering\, from detecting people'\;s opinions about products or services to extracting appointments from email. In that context\, we developed a GUI application that takes unstructured text input\, processes it\, and then detects various parameters such as parts of speech (nouns\, verbs\, adjectives\, etc)\, readability indexes\, stress positions\, etc. END:VEVENT BEGIN:VEVENT DTSTAMP;VALUE=DATE-TIME:20130519T072817Z DTSTART;VALUE=DATE-TIME:20120406T150000Z DTEND;VALUE=DATE-TIME:20120406T170000Z UID:http://www.cs.gsu.edu/?q=node/576 URL;VALUE=URI:http://www.cs.gsu.edu/?q=node/576 SUMMARY:Algorithms for Transcriptome Quantification and Reconstruction from RNA-Seq Data DESCRIPTION:
High-throughput RNA sequencing (RNA-seq) \; is becoming a technology of choice for transcriptome analyses. It \; allows us to reduce the sequencing cost and significantly increase data throughput\, but it is computationally challenging to use such data for reconstructing full-length transcripts and accurately estimating their abundances across all cell types. The common applications of RNA-seq are gene and transcript expression levels estimation\, transcriptome discovery\, and reconstruction.

The genomic diversity of viral quasispecies is a subject of great interest\, especially for chronic infections. Characterization of viral diversity can be addressed by high-throughput sequencing technology (454 Life Sciences\, Illumina\, SOLiD\, Ion Torrent\, etc). Standard assembly software was originally designed for single-genome assembly and cannot be used to assemble and estimate the frequency of closely related quasispecies sequences. This work develops parsimonious and maximum likelihood models for assembling viral quasispecies and estimating their frequencies from 454 sequencing data.

Understanding biology at the system level has gained much more interest recently due to the rapid development in genome sequencing and high-throughput measurements. Mathematical descriptions of biological systems are normally formalized using two different approaches. The deterministic method is very efficient at predicting the overall behavior of the system but ignores the inherent fluctuations and correlations at lower concentration. The stochastic method\, on the other hand\, captures the intrinsic randomness but is often mathematically intractable and computationally expensive.

Parallel processing and parallel programming concepts are currently focused on the senior and graduate college levels of Computer Science and Information Technology educational curriculums\, even though they are playing a bigger and bigger role in all types of new system and software designs. My project aims to teach parallel processing concepts to earlier students (preferably high school and early college) of the engineering and computing fields. The basic concepts of parallelism are introduced in a video-game environment. END:VEVENT END:VCALENDAR
