A General Code To Simulate The Effect Of Indirect Lightning On Overhead Lines Using Emtp-Type Programs, Hasan Jameel Hasan

Masters Theses

In this thesis, a general code is obtained to allow the simulation of the transient response of transmission lines excited by a nearby lightning stroke using EMTP–type programs, namely PSCAD and ATP.

Initially, the frequency domain modeling of single phase and multiconductor transmission lines is described and assessed by means of several application examples. As a second stage, the transmission line model is used to implement an illuminated transmission line model (line excited by an electromagnetic field excitation) using Taylor’s formulation. Then, a general code is developed in MATLAB to obtain the response of a field excited line; this effect …

Capstone Design Expo Posters

Richmond has a large quantity of trees which currently cannot be efficiently monitored for individual tree health. This lack of monitoring results in high mortality rates. It is to the benefit of the city financially that these trees are saved instead of having to be replaced. The solution includes the delivery of an Unmanned Aerial System (UAS) with modified camera technology for image processing and log identification utilizing Normalized Difference Vegetation Index (NDVI) values as numerical indicators of health. A low-cost, Federal Aviation Administration (FAA) compliant system was required for solution implementation and budget appropriations. It was decided aerial imagery …

The need addressed in this project is to accurately keep track of individuals in Richmond parks, and provide real-time actionable data for analysis and response. To do this, Satellite systems take pictures, perform object detection and send data to the Central Controller. Central Controller performs accuracy analysis and records end result. It also sends client commands to the satellite systems. Remote client gathers data from the central controller, and allows the user to change satellite system’s operation modes.

There were several constraints associated with the project 1) Supplied Power 2) Privacy protection 3) Number of satellite units (cost) 4) People …

Human Occupancy: A Non-Invasive Solution, Hamid Golgiri, Patrick Van Hoecke, Derrick Williams

Capstone Design Expo Posters

Currently, it is difficult to find an available location within a crowded setting. To solve this spatial issue, the team wants to be able to inform people of the density in commonly-occupied areas. To do this, they will need to develop Area Occupancy Device Modules (AODMs) to gather thermal readings. After which, the data will be sent to a central coordinator via mesh network communication. This coordinator will then interpret the data and display its analysis in a graphical user interface (GUI). The system is constrained in that it cannot gather defining characteristics of the people it’s observing. Additionally, the …

Uav Wireless Relay, Paul Kirchoff, Lawrence Ng, David Vieth

Capstone Design Expo Posters

Often a scenario arises in which it is necessary to collection information from a hostile environment and the safest way to do this is the deployment of a small unmanned ground vehicle (UGV). In this situation the UGV will move around the environment while sending a live data stream back to the ground base. However, there can be limits on the maneuverability and range of the UGV making it difficult to complete this mission. To solve this problem unmanned aerial vehicles (UAV) are used to assist in both the deployment of the UGV as well as handling the connection between …

Enhancing Fire Fighter Situational Awareness With Remote Uav Thermal Imaging, Jarett Chaine, Nathan Ellingson, Herve Iradukunda

Capstone Design Expo Posters

Fighting highly dynamic and unpredictable structure fires can be very challenging and dangerous for firefighters. They need full situational awareness of the fire as it evolves. In these situations, it is difficult for firefighters to gain insight on whether they are winning or losing the battle against the fire. By gathering thermal images of a burning structure, our Thermal Imaging System will be able to provide real time data to help first responders mitigate risks associated with unpredictable fire dynamics.

The FAA is currently modifying and creating more regulations to address integrating UAVs with the existing aviation network. This makes …

Dynamic Cg Display For Recovery Cranes, Tariq Haddad, Steven Lemasters

Capstone Design Expo Posters

The objective of this project is to give recovery crane operators the ability to visualize the crane's center of gravity, while picking up a load. With this ability, the operators will know when the crane is close to tipping over. Currently, no system dynamically calculates the center of gravity. This is especially important for recovery cranes, which typically work on un-level ground. This system can save a recovery crane company millions in damage to the crane, and prevent injuries to the operator or support personnel on site. Also by storing the data it can help in determining fault if a …

The senior design team used Eagle Power Quality Meters to monitor and record voltage waveforms on multiple 120V AC phases for three months and also collected real-time data of current and consumed power from the room. Based …

Gnu Radio Companion (Grc) On Software Defined Radio Platforms, Jacob Ramey, James Begemann, Richard Hite

Capstone Design Expo Posters

Software defined radio (SDR) is a method to design radio frequency (RF) signal systems using software to implement radio components that are normally implemented in hardware. Several examples of components that can be designed in SDR include RF signal filters, signal amplifiers, and signal resamplers. SDR applications include amateur radio transmission, aircraft and ship tracking, RF communications, and radio astronomy, to name a few. A great advantage of implementing a RF system in software is that the system developed in software is more flexible and upgradeable than a system designed with hardware alone.

Capstone Design Expo Posters

With the ever-increasing demand for more mobile bandwidth and higher data transfer rates, expansion into the Terahertz spectral range is inevitable. Modern Wi-Fi technologies (2.4 GHz and 5 GHz) theoretically support data rates up to only a few Gbps. A newly emerging technology, Light Fidelity (Li-Fi) provides communication with potentially Tbps rates through LED lighting. One unique benefit of Li-Fi is that it can be used simultaneously for illumination and high-speed, secure (line-of-sight) communication. Li-Fi would be best utilized in conjunction with Wi-Fi and mobile LTE networks as it is more suitable for one-way short range communication due to relatively …
