Description: This report discusses aquatic sensors and telemetric monitoring of water quality in an artificial stream. Abstract: This research report 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.

Description: This report discusses applications of wireless sensors in monitoring Indoor Air Quality in the classroom environment. Abstract: 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.

Description: This poster discusses applications of logic flowcharting with a focus in autonomous robotic operations. The focus of this research project was to determine interactivity between flowcharting algorithms and programming of various robotic platforms.

Description: This poster received 1st place in the 2013 Graduate Exhibition in the Engineering category. Abstract: High energy lasers emerged as an innovative and potential industrial tool to fabricate complex shapes on structural ceramics which is otherwise difficult using conventional machining techniques. However, obtaining a desired surface finish at higher material removal rate during laser machining of structural ceramics is still a critical issue. In this situation, the better understanding of various physical phenomena such as heat transfer, fluid flow, recoil pressure, Marangoni convection, and surface tension and its influence on the evolution of typical surface topography during laser machining could be more helpful. In light of this, this study was attempted to present the state of the art of laser machining of alumina using an integrated experimental and computational approach. A multistep computational model based on COMSOL™ Multiphysics was developed to study the effect of various physical phenomena on the generation of surface topography for various laser machining conditions. Furthermore, this process model can be used as a handy tool for the process engineers to configure the process variables (laser power, scanning speed, pulse rate, size of overlap) to obtain the specified quality characteristics. The surface topography of laser machined ...
