Friday Morning Session 1- Faculty The Implementation of Take Home Laboratories Using the NI myDAQ Hector A. Ochoa Electrical Engineering Department The University of Texas at Tyler AbstractEvery year, new technologies are been discovered, and they affect us in many different ways.They change the way we live, move, think, and learn. Kids these days are very familiar withcomputers, gaming consoles, the internet, and cell phones. For them, things like encyclopedias,chalk boards, and trigonometric tables are ancient history.

Because the focus ofthis activity has been on the exploration of the available solution space, a unique screeningprocess has been employed to assess the implication of (a) the mission, (b) the baselinevehicle, and (c) the operational scenarios on key research objectives to be defined.This study concludes that an air-launched, liquid-hydrogen-fueled, 30 minute Mach 6demonstrator (with 10 minute Mach 8 capability) provides the largest feasible solution spaceof the trades that have been examined (i.e., largest design margins with lowest technical risk)when compared with a

Digital Logic Circuit lab with TTL chips on traditional breadboardThe lab on breadboard with logic gates (all hardware based labs) is an outstanding method togive the students very basic understanding of the digital logics. However, as the circuits grew,we noticed two problems every year, viz: a) students get bored with multiple wire connectionsand get frustrated when circuit did not work, and b) it was never possible to complete all the labsprescribed in the syllabus.To alleviate these two potential problems, we adopted two new methods in the lab.

Argon gas mixed with Carbon Dioxide in theratio of 80/20, used as a detecting medium, is allowed to flow through the detector at a slowflowing rate. Three electric fields are created in each region of the detector, the highest electricfield exits in the amplification region where the GEM is located. When a fluorescence X-rayfrom a test sample interacts with the flowing gas, ionization of the gas takes place.

scheme required anoperating power higher than what the parallel port of computer could provide. Thus, a bufferbetween the computer and the control circuit was necessary to isolate the parallel port from highcurrent. A commercially available high voltage, high current, Darlington Array Buffer(ULN2003A) was used for this purpose. The buffer connected parallel port to the electroniccircuit and acted as an electronic switch.

Our hypotheses were that theexperimental group would attain higher marks on examinations and a higher percentage ofstudents would pass the course (attaining marks of A, B, or C), compared to non-ESP students.The first hypothesis was proven. As shown in Figure 1, ESP students had statistically highergrades in the Exam 1, Exam 2, Exam 3, and the final exam (p < 0.05). ESP students retained ahigher average for Exam 4, which approximated significant value (p = 0.06). Due to a holidaybreak mid-week, only one ESP session was administered to prepare students for Exam 4 and theexam covered two chapters in the textbook. This could be the reason that no significance wasfound on Exam 4. The second hypothesis was proven by comparing
