... Software simulation has become an integral component of a comprehensive learning experience in engineering and technology programs. Popular software packages include PSpice, LabVIEW, MATLAB/Simulink, and Multisim, [1][2][3][4][5][6]. This paper describes the use of software packages for developing several laboratory exercises that reinforce learning in a power systems analysis course. ...

Software Simulation to Reinforce Learning in a Power Systems Analysis Course

... At the time of NEBP team selection, our ballooning framework consisted of several balloon payloads and ground stations. On the balloon side, our payloads were for multiple Pi cam-based video streaming [2] , 900 MHz RF-based balloon tracking, 144 MHz APRS-based balloon tracking, 1.6 GHz Iridium-based balloon tracking, 2 GHz cellphone-based balloon tracking [3] , and 2.8/5.8 GHz microwave downlinks for real-time video transmission. ...

... Compared to the desk robots, the mobile robots are more complicated due to their dynamic working environment. Nowadays especially, more and more mobile robots are being employed in life science laboratories [7], and their cooperation with other existing automated systems and facilities is a considerable issue. Indeed, in considering this issue, the construction of a smart common control system between the mobile robots and the higher laboratory Process Management System (PMS) is an effective option. ...

... For each student outcome, two questions may be asked: i) if the project provided opportunities for the student to improve on the learning outcome and ii) if the student actually did improve that learning outcome by participating in the project. The specific text for all survey questions and the exact methodology we have used can be found in [11]. These surveys have indicated the efficacy of this project for both providing students with opportunities to improve and helping them actually improve the ABET "(a) through (k)" outcomes. ...

An Approach to Promoting STEM Interest via Near-Space Ballooning

... The High Altitude Radiation Detection payload #3 [2], or HARD-PL03, is a HASP payload that successfully met all requirements and milestones as per the aforementioned schedule and deliverables. The authors' student team had initially designed, built, and flown a similar payload for the HASP 2012 flight [3]. The HARD-PL02, however, revealed several design problems during flight that prevented it from collecting the desired science data. ...

... The IM is a custom design developed in house with the assistance of undergraduates, and the circuit for a single channel is shown in Figure 2 [2] . Because the SiPM is a current output device, the first stage of preamplification would be ideally done by a transimpedance amplifier, which converts the current output of the SiPM into a voltage (VO,TIA). ...

... This paper describes how to alternatively estimate the run time of an electronic device powered by a battery via a dc-dc converter in a way that typical engineering students can easily adopt without a complete understanding of the details of battery-related parameters and characteristics. For the purposes of our illustration, we utilize a set of electronic devices used to conduct video streaming in a balloon flight during the 2017 total solar eclipse [5] [6] . ...

Run-Time Estimation of a Battery-Powered Video-Streaming Payload for Balloon Flights

... OR the 2017 solar eclipse ballooning, the live streaming of the videos capturing the shadows of the solar eclipse was one of the main objectives. All teams who participated in the 2017 solar eclipse ballooning project were initially provided with a baseline ballooning system [1][2] that consisted of a ground station and four standard payloads for still image, video, Iridium-based tracking, and cut-down. In particular, the standard video payload for live streaming was primarily composed of a Raspberry Pi 2 Model B board with a Pi-camera module to capture highdefinition video during balloon flight and a 5.8 GHz Ubiquiti Rocket M5 modem to transmit the video to its counterpart M5 modem on the ground station. ...

... In a globalized world, multidisciplinarity has become very important, since it is difficult to imagine that the teaching-learning process can occur in isolation. The benefits of multidisciplinarity have been mentioned by authors such as [16][17][18][19][20][21][22][23][24]. In this approach has been developed a multidisciplinary course. ...
