This paper investigates the tracking of Unmanned Aerial Vehicles (UAV) using video feed. Gaussian Mixture Models (GMM) are used to detect the presence of the UAV from a video feed. If the feed is reliable the position of the UAV is detected and tracked. In case the feed is interrupted or becomes unreliable, a Kalman filter is used to predict the location of the UAV. To study the ability of the filter to track the UAV, an actual video capture of flying drone is used, a section of the video is removed to simulate an interruption of the feed. The results show the ability of the filter to accurately predict the location of UAV.

On the development of a tool to detect Pinocchio effect using facial heat distribution
Published 2020
2020 SoutheastCon
SoutheastCon, 2020
Thermography combined with experimental psychology and image processing has great potential in many applications including marketing, social media, and security. One of the challenges of adopting this tool is the large amount of data needed to get accurate results. Currently, an experimental psychologist manually detects and classifies each thermograph, resulting in time consumption and inefficiency that prevents large data analysis, leading to unreliable results. The Pinocchio effect refers to changes in nasal temperature when someone lies. This is a result of changes of blood flow in the area. This work develops a tool that helps detect and track this effect. The tool allows for large data to be collected and analyzed.

Coded Rumble Strips to Enhance Reliability of Autonomous Vehicles
Published 01/01/2018
2018 IEEE INTERNATIONAL CONFERENCE ON ELECTRO/INFORMATION TECHNOLOGY (EIT), 2018, 296 - 301
Road strips are used worldwide to alert drivers to changing road conditions and potential danger. These markers are currently passive and work by causing vehicle to vibrate, alerting drivers to pay attention to the road and road signs. In this work, we propose encoding the markers so that a message can be exchanged to help drivers and enhance autonomous vehicle performance. The instants vibrations occur can carry information that can be used by the vehicle. This information can be a warning message or information about the location. The proposed solution can be used by autonomous vehicles or ordinary vehicles equipped with motion sensing capabilities. Utilizing motion gyroscopic sensors, we illustrate how a message can be transferred and decoded from these markers.

Evaluation of reference generation algorithms for dispatching solar PV power
Published 2018
SoutheastCon 2018
IEEE SoutheastCon 2018, 04/19/2018–04/22/2018, St. Petersburg, Florida
This paper aims to develop a low-cost energy storage system by evaluating reference generation algorithms for dispatching solar power for 1 MW photovoltaic (PV) arrays. Based on battery state of charge (SOC), rule-based algorithms are developed to adjust the grid reference power for each one-hour dispatching period. In this paper, several rule-based algorithms are used to control the SOC of the battery that plays a significant role to design cost-effective energy storage system. The price comparison is made between two kinds of energy storage system (i) Battery only (ii) Battery+ Supercapacitor (SC), where a low pass filter is used to allocate power between battery and SC. The most economical energy storage system is developed through extensive simulations in MATLAB/Simulink environment. The results show that the hybrid energy storage system (HESS), combination of battery and SC, outperforms a battery-only operation.

This paper studies the optimum (most economical) scaling of a battery and supercapacitor hybrid storage for 1 MW photovoltaic (PV) arrays for a one hour dispatching period for an entire day. The optimization is based on the time constant of a low pass filter (LPF) that is used to allocate the power between a battery and a supercapacitor (SC). This paper also presents the price comparison between lead-acid and li-ion battery frameworks. Extensive simulations were conducted for thorough analysis of various hybrid energy storage system (HESS) combinations. According to the results, HESS outperforms battery or SC-only operation.

In this work, a novel model of a wave energy converter that utilizes a slider crank power take-off system (PTOS) has been studied to determine maximum energy extraction. This system includes a buoy, slider crank linkage, and generator with a gear box. With a regular sinusoidal wave excitation force, effects of three parameters on the system are analyzed. These include the slider crank radius, connecting rod length, and phase lock offset. It is found that the slider crank radius has the largest effect on total energy extracted. Under irregular wave conditions only the effect of phase lock offset is analyzed. The results show that the control system can exhibit small percentages of performance degradation without large adverse effects on the overall energy production.

On the Analysis of Road Surface Conditions Using Embedded Smartphone Sensors

2017 8th International Conference on Information and Communication Systems (ICICS), 177 - 181
International Conference on Information and Communication Systems (ICICS), 04/04/2017–04/06/2017, Irbid, Jordan
Road conditions play a critical role in ensuring traffic safety and reducing traffic jams and congestions. Ensuring healthy conditions require constant monitoring to detect and predict potential road deterioration. This work proposes a low-cost solution that takes advantage of sensory capabilities of smartphones. By recording Gyro rotation sensor data, we show that abnormalities can be detected by calculating the second moment of sensor data. Our work is validated by drive tests that show results are consistent and repeatable. The work also proposed a dynamic time warping technique to measure similarity between drive results and to obtain accurate representation of multiple drives data.
