Mapping Reality Into Virtual Worlds, Josh Mcfarlane
Mapping Reality Into Virtual Worlds, Josh Mcfarlane
Computer Science and Computer Engineering Undergraduate Honors Theses
As virtual worlds become more prevalent, they become increasingly useful as a means of information dissemination. This thesis examines the possible connections between real world objects and their virtual world counterparts. We look at how, by attaching sensors to an object, or by using a smart object with embedded sensors, the information can be relayed to a server. From this information, it will be possible to create a duplicate object in the virtual world and have it mirror the real world object in terms of state and movement. Almost all current solutions for remotely viewing a room or area are …
Steganography In Ipv6, Barret Miller
Steganography In Ipv6, Barret Miller
Computer Science and Computer Engineering Undergraduate Honors Theses
Steganography is the process of hiding a secret message within another message such that it is difficult to detect the presence of the secret message. In other words, the existence of the secret message is hidden. A covert channel refers to the actual medium that is used to communicate the information such as a message, image, or file. This honors thesis uses steganography within the source address fields of Internet Protocol Version 6 (IPv6) packets to create a covert channel through which clandestine messages are passed from one party to another. A fully functional computer program was designed and written …
Service Oriented Transitive Closure Solution, Jonathan Baran
Service Oriented Transitive Closure Solution, Jonathan Baran
Computer Science and Computer Engineering Undergraduate Honors Theses
The goal of this project is a service based solution that utilizes parallel and distributed processing algorithms to solve the transitive closure problem for a large dataset. A dataset may be view conceptually as a table in a database, with a physical structure representing a file containing a sequence of records and fields. Two records are said to be transitively related if and only if they are directly related due to sharing of one or more specific fields, or a sequence may be made from one record to the other under the condition that all intermediate entries are related the …
Location-Based Hashing For Querying And Searching, Felix Ching
Location-Based Hashing For Querying And Searching, Felix Ching
Computer Science and Computer Engineering Undergraduate Honors Theses
The rapidly growing information technology in modern days demands an efficient searching scheme to search for desired data. Locality Sensitive Hashing (LSH) is a method for searching similar data in a database. LSH achieves high accuracy and precision for locating desired data, but consumes a significant amount of memory and time. Based on LSH, this thesis presents two novel schemes for efficient and accurate data searching: Locality Sensitive Hashing-SmithWaterman (LSH-SmithWaterman) and Secure Min-wise Locality Sensitive Hashing (SMLSH). Both methods dramatically reduce the memory and time consumption and exhibit high accuracy in data searching. Simulation results demonstrate the efficiency of the …
A Timer Module For An 8051 Microcontroller, Troy England
A Timer Module For An 8051 Microcontroller, Troy England
Electrical Engineering Undergraduate Honors Theses
A timer module for an 8051 Microcontroller is designed from the ground up. It could potentially be integrated into a larger 8051 for use in lunar and Martian missions. It follows through a synchronous digital design flow from HDL code through layout verification. The timer shows functionality at 100MHz with some minor glitches.
Aquatic Bacteria Removal Using Carbon Nanotubes, Suvish Melanta
Aquatic Bacteria Removal Using Carbon Nanotubes, Suvish Melanta
Biological and Agricultural Engineering Undergraduate Honors Theses
The purpose of this project is to explore the functionality of carbon nanotubes as a bacterial removal method, specifically towards water-borne bacterial pathogens in wastewater by utilizing its unique magnetic and bacteria-binding properties. The general protocol set for this research follows five steps: 1) Preparation of wastewater media, 2) preparation of CNT culture, 3) preparation of reaction mixture with CNTs for bacterial binding, 4) magnetic separation of bacteria-bound-CNT clusters and, 5) assessment of supernatant. The CNTs effectively removed bacterial contaminants in the wastewater (10%, v/v) after the sand filtration process from the Paul R. Noland Wastewater Facility at Fayetteville, Arkansas. …
Benefits Of Leed Designs In Arkansas K-12 Schools, Philip Thrift
Benefits Of Leed Designs In Arkansas K-12 Schools, Philip Thrift
Mechanical Engineering Undergraduate Honors Theses
This paper provides and evaluation of an existing LEED certified sustainable green building for energy-efficiency, environmental impact, economic value, and occupant health. The new Bethel Middle School located in Bryant, Arkansas was the first LEED (Leadership in Energy and Environmental Design) certified public school building in the state. Based on actual building specifications and validated with the first year's utility bills, a simulation model was used to evaluate various design aspects of the school building. The building's baseline energy usage was compared with numerous energy and environmental scenarios. Results include both environmental and economic assessments. Overall, the study found that …
Multiuav2 Agent Swarming For Distributed Atr Simulation, Kyle White
Multiuav2 Agent Swarming For Distributed Atr Simulation, Kyle White
Computer Science and Computer Engineering Undergraduate Honors Theses
Traditional automatic target recognition (ATR) is performed by unmanned aerial vehicles (UAVs) depending on a central control tower to provide the high level organization of the system. The UAVs fly through a region of interest to identify targets and relay all communication through a central control tower. The centralized approach to ATR has limited fault-tolerance, scalability with regards to the number of UAVs, and susceptibility to malicious attacks on the central tower [2]. A swarm-driven alternative [1] is extended with a communication control scheme to address fault-tolerance and scalability while utilizing the higher onboard processing power now available for UAVs …

Visualization Of An Approach To Data Clustering, Marisabel Guevara
Visualization Of An Approach To Data Clustering, Marisabel Guevara
Computer Science and Computer Engineering Undergraduate Honors Theses
Using visualization and clustering goals as guidelines, this thesis explores a graphic implementation of a data clustering technique that repositions vertices by applying physical laws of charges and springs to the components of the graph. The resulting visualizations are evidence of the success of the approach as well as of the data sets that lend themselves to a clustering routine. Due to the visual product of the implementation, the algorithm is most useful as an aid in understanding the grouping pattern of a data set. Either for a rapid analysis or to assist in presentation, the visual result of the …
