Hardware/Software Codesign In A Compact Ion Mobility Spectrometer Sensor Systemfor Subsurface Contaminant Detection, Sin Ming Loo, Jonathan P. Cole, Molly M. Gribb Jan 2008

Hardware/Software Codesign In A Compact Ion Mobility Spectrometer Sensor Systemfor Subsurface Contaminant Detection, Sin Ming Loo, Jonathan P. Cole, Molly M. Gribb

Electrical and Computer Engineering Faculty Publications and Presentations

A field-programmable-gate-array-(FPGA-) based data acquisition and control system was designed in a hardware/software codesign environment using an embedded Xilinx Microblaze soft-core processor for use with a subsurface ion mobility spectrometer (IMS) system, designed for detection of gaseous volatile organic compounds (VOCs). An FPGA is used to accelerate the digital signal processing algorithms and provide accurate timing and control. An embedded soft-core processor is used to ease development by implementing nontime critical portions of the design in software. The design was successfully implemented using a low-cost, off-the-shelf Xilinx Spartan-III FPGA and supporting digital and analog electronics.


A Framework For Efficient Data Distribution In Peer-To-Peer Networks., Darshan Purandare Jan 2008

A Framework For Efficient Data Distribution In Peer-To-Peer Networks., Darshan Purandare

Electronic Theses and Dissertations

Peer to Peer (P2P) models are based on user altruism, wherein a user shares its content with other users in the pool and it also has an interest in the content of the other nodes. Most P2P systems in their current form are not fair in terms of the content served by a peer and the service obtained from swarm. Most systems suffer from free rider's problem where many high uplink capacity peers contribute much more than they should while many others get a free ride for downloading the content. This leaves high capacity nodes with very little or no …


Elimu 2.0: Investigating The Use Of Web 2.0 For Facilitating Collaboration In Higher Education., Bajuna R. Salehe Jan 2008

Elimu 2.0: Investigating The Use Of Web 2.0 For Facilitating Collaboration In Higher Education., Bajuna R. Salehe

Dissertations

The latest web innovations and technologies which has made the Web into a ‘Platform’, are become increasingly applied in the higher education arena. Tools such as Google docs, Google groups, Wikis, Blogs, RSS and Podcasting are gradually becoming more popular within higher education in teaching and learning. Yet their huge potentials have not been fully explored. Collaboration and knowledge sharing are common terms in higher education, and in the corporate world of the today’s knowledge economy. However better infrastructure and facilities that enable these important issues are yet to be set and fully utilised in higher education. In the higher …

Partitioning Of The Degradation Space For Ocr Training, Elisa H. Barney Smith, Tim Andersen Jan 2006

Partitioning Of The Degradation Space For Ocr Training, Elisa H. Barney Smith, Tim Andersen

Electrical and Computer Engineering Faculty Publications and Presentations

Generally speaking optical character recognition algorithms tend to perform better when presented with homogeneous data. This paper studies a method that is designed to increase the homogeneity of training data, based on an understanding of the types of degradations that occur during the printing and scanning process, and how these degradations affect the homogeneity of the data. While it has been shown that dividing the degradation space by edge spread improves recognition accuracy over dividing the degradation space by threshold or point spread function width alone, the challenge is in deciding how many partitions and at what value of edge …

A Study Of Style Effects On Ocr Errors In The Medline Database, Penny Garrison, Diane Davis, Tim Andersen, Elisa Barney Smith Jan 2005

A Study Of Style Effects On Ocr Errors In The Medline Database, Penny Garrison, Diane Davis, Tim Andersen, Elisa Barney Smith

Electrical and Computer Engineering Faculty Publications and Presentations

The National Library of Medicine has developed a system for the automatic extraction of data from scanned journal articles to populate the MEDLINE database. Although the 5-engine OCR system used in this process exhibits good performance overall, it does make errors in character recognition that must be corrected in order for the process to achieve the requisite accuracy. The correction process works by feeding words that have characters with less than 100% confidence (as determined automatically by the OCR engine) to a human operator who then must manually verify the word or correct the error. The majority of these errors …


Text Degradations And Ocr Training, Elisa H. Barney Smith, Tim Andersen Jan 2005

Text Degradations And Ocr Training, Elisa H. Barney Smith, Tim Andersen

Electrical and Computer Engineering Faculty Publications and Presentations

Printing and scanning of text documents introduces degradations to the characters which can be modeled. Interestingly, certain combinations of the parameters that govern the degradations introduced by the printing and scanning process affect characters in such a way that the degraded characters have a similar appearance, while other degradations leave the characters with an appearance that is very different. It is well known that (generally speaking) a test set that more closely matches a training set will be recognized with higher accuracy than one that matches the training set less well. Likewise, classifiers tend to perform better on data sets …

Interactive Lego Robots Learning In A Controlled Environment, Jonathan Mcgehee Dec 2003

Interactive Lego Robots Learning In A Controlled Environment, Jonathan Mcgehee

Mahurin Honors College Capstone Experience/Thesis Projects

This paper reports on learning in autonomous Lego robots programmed to play soccer. The specific focus here is upon how different behaviors can be learned by two identical robots, based on the different type of feedback they receive from the environment. After being constructed with the same design and the same software, two Lego robots are able to perform the same basic soccer actions, such as moving to the ball, determining where the goal is. and kicking the ball. A non-deterministic version of the Q-step learning algorithm is then used to allow a robot to learn a correct series of …
