Report Poster

The team developed a sensor setup and educational module that allows students to collect real-time data of an artificial stream experiment. This research covers the use of a wireless sensor network (WSN) using the ZigBee protocol to remotely monitor an artificial aquatic ecosystem. Field tests were conducted at the University of North Texas Water Research Facility to compare the accuracy of a high-end standard YSI multi probe system to a cost efficient lab developed sensor cluster, which would be used in the classroom to bring more real-world experiences in engineering to students. Measurements were recorded every 10 seconds for pH, dissolved oxygen, and temperature for a period of 24 hours. Comparison results show a 10 percent degree of variability in dissolved oxygen possibly due to the sensitivity of the DO sensors themselves. On the other hand, temperature and pH measured less than a 5 percent error.

Report Poster

While the struggle with energy, pollution, congestion, and economy intensifies, many private and public vehicles are running barely occupied. Mean occupancy rate of personal vehicle trips in the United States is 1.6 persons per vehicle mile. Ridesharing is potentially a solution to the myriad of problems our modern society is facing. With the wide availability of low cost geo-locating devices, smartphones, and wireless networks, large-scale real-time ridesharing becomes possible.

The focus of this research project was to analyze and collect travel trajectories to calculate carbon footprints under different travel modes and identify ways to reduce it. We collected trajectory data using GPS from RET participants and translated it into energy consumption to determine if shared ride modes were available and the corresponding amount of reduced carbon footprints. We also researched issues associated with ridesharing such as coordination of routes, safety concerns, time costs, and social discomfort. Ridesharing is a possible solution to help reduce increasing amount of carbon emissions in our growing communities.

The focus of this research project was to determine interactivity between flowcharting algorithms and programming of various robotic platforms. We explored various flowcharting schemes and applications and implemented them on programming platforms for Acroname Garcia robots and LEGO Mindstorms NXT 2.0. The flowcharting and programming experiences have been used to develop a lesson plan on logic and the fundamentals of programming that will be used in high school Engineering Design and Problem Solving classes.

Report Poster

The focus of this research project was to investigate Indoor Air Quality monitoring technologies, government regulations and policies, and best practices to improve IAQ while minimizing the adverse effect of poor IAQ, specifically in the classroom environment. The investigation involved two parts: development of a cost effective indoor air quality prototype sensor unit and the deployment of the unit to monitor 5 different indoor locations. The data from the sample monitoring locations will then be compiled and analyzed. In addition, researching the literature was instrumental in establishing the parameters for testing the environment and conducting experiments. This provided valuable experiences which will be shared with both district teachers and students
