Item SETS Location Identification and Solar Power Regarding Bicycle Share Stations at UH Campus(2017-10-12) Vargas, Jesus; Palwala, Mohammad; Elizarraras, Abraham; Huynh, Tu"Bicycle Share at UH" focuses on creating and testing innovative integrated systems, and processes that will enable access to transmit and improve transit mobility on a unique urban campus. Houston is the 4th largest city in the United States and its population is expected to grow 7 million in 2015 to 10 million in 2040. About 70% of the residents in the area have poor access to public transit. The solar power group was in charge of identifying key problems revolving around the placement of bicycle share stations around UH campus. An important issue regarding students, is that they are not able to make it to their classes on time. This problem is intensified by moving most economy parking to the Energy Reserach Park lots. To alleviate this issue we proposed to help find the best loations for bike placement so that students can move quickly and safely through our campus. In order to maintain these remote locations on campus we initiated the development and implementation of an embedded solar panel system. The end goal was to implement a theoretical bike station solution designed for Coogs by Coogs.Item SETS Student Discovery and Analysis Regarding Bicycle Sharing Stations at UH Campus(2017-10-12) Elizarraras, Abraham; Alonso, Julio A.; Palwala, Mohammad; Isago, Masaki"Bicycle Share @ UH" focuses on creating and testing innovative and integrated system and process that will enable access to transmit and improve transit mobility on an unique urban campus.

Payment PreferenceItem Total Electron Content Analysis(2018-10-18) Cortina-Sanchez, Sergio; Elizarraras, Abraham; Gomez, Carlos; King, Barton; Trevino, JorgeTotal electron content, is an important variable in satellite communication as well as astronomy. TEC is the total number of electrons present in the path of a transmission and a receiver, and depending upon its magnitude can negatively affect the accuracy of GPS navigation on the scale of tens of meters. TEC is influenced in drastic ways by its location, the time of day, and by space weather events such as the solar cycle, and interaction of magnetosphere with solarwinds. Our method of ascertaining our results was by installing a receiver on the rooftop of the University of Alaska, Fairbanks and retrieving data from the receiver every 24 hours over the course of two weeks.Once we returned to the University of Houston we began our data analysis with a variety of software. The TEC content was observed to rise in the evenings, and cleared during periods of high aurora activity. Additional processing and analysis of the results are ongoing for the periods of greatest solar activity. By understanding the effect on TEC due to space weather events we gain the ability to improve accuracy of GPS and radio transmissions through the ionosphere, and potentially safeguard ourselves against unpredictable events.
