Evaluating The Presence Of A Victim Cache On An Arm Processor, Lakshmi Vidya Peri

Computer Science Graduate Projects and Theses

Mobile processor is a CPU designed to save power. It is found in mobile computers and cell phones. A CPU chip, designed for portable computers, is typically housed in a smaller chip package, but more importantly, in order to run cooler, it uses lower voltages than its desktop counterpart and has more "sleep mode" capability. A mobile processor can be throttled down to different power levels and/or sections of the chip can be turned off entirely when not in use. ARM is a 32-bit reduced instruction set computer (RISC) instruction set architecture (ISA). The relative simplicity of ARM processors makes …

A Robust Rgbd Slam System For 3d Environment With Planar Surfaces, Po-Chang Su, Ju Shen, Sen-Ching S. Cheung

Computer Science Faculty Publications

With the increasing popularity of RGB-depth (RGB-D) sensors such as the Microsoft Kinect, there have been much research on capturing and reconstructing 3D environments using a movable RGB-D sensor. The key process behind these kinds of simultaneous location and mapping (SLAM) systems is the iterative closest point or ICP algorithm, which is an iterative algorithm that can estimate the rigid movement of the camera based on the captured 3D point clouds. While ICP is a well-studied algorithm, it is problematic when it is used in scanning large planar regions such as wall surfaces in a room. The lack of depth …

Forensic Analysis Of Whatsapp On Android Smartphones, Neha S. Thakur

LSU New Orleans Theses and Dissertations

Android forensics has evolved over time offering significant opportunities and exciting challenges. On one hand, being an open source platform Android is giving developers the freedom to contribute to the rapid growth of the Android market whereas on the other hand Android users may not be aware of the security and privacy implications of installing these applications on their phones. Users may assume that a password-locked device protects their personal information, but applications may retain private information on devices, in ways that users might not anticipate. In this thesis we will be concentrating on one such application called 'WhatsApp', a …

Towards Decrypting Attractiveness Via Multi-Modality Cue, Tam Nguyen, Si Liu, Bingbing Ni, Jun Tan, Yong Rui, Shuicheng Yan

Computer Science Faculty Publications

Decrypting the secret of beauty or attractiveness has been the pursuit of artists and philosophers for centuries. To date, the computational model for attractiveness estimation has been actively explored in the computer vision and multimedia community, yet with the focus mainly on facial features. In this article, we conduct a comprehensive study on female attractiveness conveyed by single/multiple modalities of cues, that is, face, dressing and/or voice; the aim is to discover how different modalities individually and collectively affect the human sense of beauty.

To extensively investigate the problem, we collect the Multi-Modality Beauty (M²B) dataset, which is …

Segmenting Tables Via Indexing Of Value Cells By Table Headers, Sharad C. Seth, George Nagy

School of Computing: Conference and Workshop Papers

Correct segmentation of a web table into its component regions is the essential first step to understanding tabular data. Our algorithmic solution to the segmentation problem relies on the property that strings defining row and column header paths uniquely index each data cell in the table. We segment the table using only “logical layout analysis” without resorting to any appearance features or natural language understanding. We start with a CSV table that preserves the 2- dimensional structure and contents of the original source table (e.g., an HTML table) but not font size, font weight, and color. The indexing property of …

Abstract: In the fall of 2010, faculty in the School of Interactive Games & Media at the Rochester Institute of Technology began the initial planning for an achievement system meant to recognize and reward student engagement in non-curricular activities—specifically activities that successful graduates of the program regularly cited as significant factors in their undergraduate experience. This paper describes the design process used to create the initial version of the Just Press Play system, the results of the implementation during the 2011-12 academic year, and the significant redesign of the system that took place based on assessment of the first year …

Equivalence Checking For High-Assurance Behavioral Synthesis, Kecheng Hao

Dissertations and Theses

The rapidly increasing complexities of hardware designs are forcing design methodologies and tools to move to the Electronic System Level (ESL), a higher abstraction level with better productivity than the state-of-the-art Register Transfer Level (RTL). Behavioral synthesis, which automatically synthesizes ESL behavioral specifications to RTL implementations, plays a central role in this transition. However, since behavioral synthesis is a complex and error-prone translation process, the lack of designers' confidence in its correctness becomes a major barrier to its wide adoption. Therefore, techniques for establishing equivalence between an ESL specification and its synthesized RTL implementation are critical to bring behavioral synthesis …

Channels: Easy Video Content Consumption, Alexander R. Ledwith

Computer Engineering

The idea for this project is to take a user’s digital movie and television show library, and organize the individual videos into lists that will continuously and concurrently play like cable TV channels. This means that when a list of channels is switched to, video content will automatically start playing, possibly in the middle, based on a schedule. It should serve the needs of the user by allowing the user to quickly watch any of their existing channels, easily add a new channel based on chosen criteria or manual selection, and easily add new video content. In addition, the product …

Misheard Me Oronyminator: Using Oronyms To Validate The Correctness Of Frequency Dictionaries, Jennifer G. Hughes

Master's Theses

In the field of speech recognition, an algorithm must learn to tell the difference between "a nice rock" and "a gneiss rock". These identical-sounding phrases are called oronyms. Word frequency dictionaries are often used by speech recognition systems to help resolve phonetic sequences with more than one possible orthographic phrase interpretation, by looking up which oronym of the root phonetic sequence contains the most-common words.

Our paper demonstrates a technique used to validate word frequency dictionary values. We chose to use frequency values from the UNISYN dictionary, which tallies each word on a per-occurance basis, using a proprietary text corpus, …

Mantis: A Predictive Driving Directions Recommendation System, Christopher Hoover

Master's Theses

This thesis presents Mantis, a system designed to evaluate possible driving routes and recommend the optimal route based on current and predicted travel conditions. The system uses the Bing Maps REST service to obtain a set of routes. Traffic data from the California Department of Transportation’s Performance Measurement System (PeMS) is then used to estimate travel times for these routes. In addition to simple travel time estimation based on instantaneous traffic conditions, Mantis can use historic data to predict traffic speeds at future times. This allows Mantis to more effectively account for regularly repeating traffic patterns such as rush hour, …

Automated Timeline Anomaly Detection, Joshua M. Barone

LSU New Orleans Theses and Dissertations

Digital forensics is the practice of trained investigators gathering and analyzing evidence from digital devices such as computers and smart phones. On these digital devices, it is possible to change the time on the device for a purpose other than what is intended. Currently there are no documented techniques to determine when this occurs. This research seeks to prove out a technique for determining when the time has been changed on forensic disk image by analyzing the log files found on the image. Out of this research a tool is created to perform this analysis in automated fashion. This tool …

An Exploratory System For Collaborative Decision-Making In Community Planning, Aaron Dale Wells

Computer Science Graduate Projects and Theses

Community planning problems differ from those of science, technology, and mathematics as they are not solvable with logical-empiricism. Their solutions are influenced by technology, politics, style, economics, as well as the personalities and experience of those individuals collaborating on the solution. Obtaining cooperation of the stakeholders to implement community planning solutions can be cumbersome or simply cause failure in the implementation of plans. Yet, if the stakeholders had a real handle on the cost and benefits the literature suggests that cooperation can evolve.

In this project, we explore building a reliable cost and benefit model for a set of input …
