Drowning is the third main reason for unintended deaths globally, in keeping with the World Well being Group. The deaths disproportionately affect low- and middle-income communities, whose seashores are inclined to lack lifeguards due to restricted funds. Final 12 months 104 drownings of the 120 reported in america occurred on unstaffed seashores.
That fueled Angelina Kim’s drone mission. Kim is a senior at the Bishop’s College in La Jolla, Calif. Her Autonomous Unmanned Aerial Automobile (UAV) System for Ocean Hazard Recognition and Rescue: Scout and Rescue UAV Prototype mission was showcased in Might at Regeneron’s Worldwide Science and Engineering Truthful (ISEF) in Los Angeles.
Kim mission took first place on this 12 months’s IEEE Presidents’ Scholarship competitors: a prize of US $10,000 payable over 4 years of undergraduate college examine. The IEEE Basis established the award to acknowledge a deserving pupil whose mission demonstrates an understanding {of electrical} or electronics engineering, pc science, or different IEEE discipline of curiosity. The scholarship is run by IEEE Academic Actions.
Kim has lengthy been motivated to assist these in want, particularly after her mom’s sickness when Kim was a younger baby.
“I’ve been decided to seek out methods to create a safer neighborhood utilizing expertise my complete life,” she says. “I spotted as I bought extra into robotics that expertise can be utilized to guard these in my neighborhood.”
Kim and the second- and third-place scholarship winners additionally acquired a complimentary IEEE pupil membership.
As well as, to mark the scholarship’s quarter century, IEEE established a twenty fifth anniversary award to honor a mission that’s more likely to make a distinction. It additionally was given out at ISEF.
Drones that may save swimmers’ lives

The autonomous UAV lifeguard system consists of two kinds of drones: a scout craft and a rescue craft. The scout drone surveys roughly 1 kilometer of shoreline, taking pictures and analyzing them for rip currents, which will be lethal to swimmers.
The scout drone “implements a brand new model of differential body displacement and a brand new depth-risk mannequin,” Kim says. The displacement compares the earlier picture to the following one and notes in what route a wave is shifting. The algorithm detects rip currents and, utilizing the depth-risk mannequin, focuses on robust currents within the deep finish—that are extra harmful. If the scout drone detects a swimmer caught in such a present, it summons the rescue drone. That drone drops a flotation system outfitted with a heaving rope and might pull the endangered swimmer to shore, Kim says.
The rescue drones function with roll-and-pitch tilt rotors, permitting them to fly in no matter route and orientation they should.
Kim says she was shocked and ecstatic to obtain the award: “It felt like a dream come true as a result of IEEE has been the group I’ve at all times needed to be part of.”
She introduced her mission at two IEEE gatherings this 12 months: the IEEE Worldwide Convention on Management and Automation and the IEEE Worldwide Convention on Automated Management and Clever Techniques.
Kim says a number of the roadblocks she encountered together with her mission have made her a greater engineer.
“If every thing goes completely, then there is not going to be a lot to be taught,” she says. “However in the event you fail—like by chance flying your drone into your mother and father’ home, like I did—you get alternatives to be taught.”
She plans to review electrical or mechanical engineering in school. Finally, she says, she want to construct and mass-produce applied sciences that assist communities at a low value.
Recognizing carbon dioxide in soil
Extreme carbon dioxide is a number one trigger of world warming and local weather change, in keeping with NASA. Burning fossil fuels is a outstanding supply of carbon dioxide, but it surely additionally will be launched from the bottom.
“Folks don’t account for the massive quantities of CO2 that come from soil,” second-place winner Sahiti Busulu says. “Carbon flux is the speed at which CO2 is exchanged between the soil and the environment, and might account for 80 % of internet ecosystem carbon trade.”
Busulu is a senior on the Foundation Unbiased highschool in Fremont, California.
Ecosystem carbon trade is the switch of carbon dioxide between the environment and the bodily setting. As a result of the trade will not be usually accounted for, there’s a spot in information. To supply extra info, Busula created the Carboflux Community.
The sensor node is designed to measure enhanced flux CO2 and add to the World Ecosystem Monitoring Community. The system accommodates three fundamental subunits: a flux chamber, an under-soil sensor array, and a microcontroller with an information transmission unit. The enclosed flux chamber homes sensors. When CO2 accumulates within the chamber, the linear improve in carbon dioxide focus is used to calculate carbon flux. The second subunit makes use of the gradient technique, which measures flux utilizing Fick’s legislation, trying on the CO2 gradient within the soil, and multiplying it with the soil diffusivity coefficient. Sensors are put within the floor at completely different depths to measure the gradient.
“Carboflux makes use of the gasoline focus between the depths to foretell what the soil carbon flux can be,” Bulusu says.
The system is automated and supplies real-time information via microcontrollers and a modem. The system research soil flux, each above and beneath the bottom, she says.
“It is ready to be scaled domestically and globally,” she says, “serving to to pinpoint native carbon sources and carbon sinks.” The information additionally may give scientists a large-scale international perspective.
Bulusu got here up together with her concept with assist from mentors and professors Helen Dahlke and Elad Levintal.
“They advised me in regards to the lack of world carbon flux information, and the thought for a community of CO2 flux sensors,” Bulusu says. “This information is required for local weather modeling and mitigation methods.
“I didn’t suppose I’d be so passionate a few mission. I really like science, however I by no means thought I’d be somebody who would sit within the rain and chilly for hours attempting to determine an issue. I used to be so invested on this mission, and it has come up to now.”
Bulusu plans to pursue a level in pc science or environmental science. No matter discipline she choses, she says, she needs to enhance the setting with the expertise she creates.
She was awarded a $600 scholarship for her mission.
Accessible communication for ALS sufferers
Xiangzhou “Jonas” Solar has been volunteering to assist individuals with amyotrophic lateral sclerosis, also called Lou Gehrig’s illness. After Solar and his household frolicked serving to ALS sufferers and aiding caretakers in Hong Kong and america, he was impressed to create a cellular app to help them. He’s a senior on the Webb College of California, in Claremont.
Whereas volunteering, he observed that ALS sufferers had bother speaking due to the illness.
“ALS damages neurons within the physique, and sufferers steadily lose the power to stroll, transfer their palms, and communicate,” he says. “My goal with Gaze Hyperlink was to construct a cellular utility that might assist ALS sufferers to sort sentences with solely their eyes and with out exterior help.”
The low-cost smartphone app makes use of eye-gesture recognition, AI sentence era, and text-to-speech capabilities to permit individuals with disabilities linked to ALS to make use of their telephone’s front-end digicam to speak.
Gaze Hyperlink now works with three languages: English, Mandarin, and Spanish.
Customers’ eye gestures are mapped to phrases and pronunciations, and an AI next-word-prediction function is included.
Solar’s ardour for his mission is palpable.
“My favourite second was once I introduced a prototype of Gaze Hyperlink to a caretaker from the ALS Affiliation, they usually have been overjoyed,” he says. “That second was actually emotional for me as a result of I used to be motivated by these sufferers. It gave me an enormous sense of feat that I may lastly assist them.”
Solar acquired a $400 scholarship for putting third.
He says he plans to make use of his engineering know-how to assist individuals with disabilities. He’s obsessed with design and visible arts as properly, and says he hopes to mix them along with his engineering abilities.
Gaze Hyperlink is out there via Google Play.
An inclusive approach to code
The twenty fifth anniversary award, within the quantity of $1,000, was given to Abishek Shah, a senior at Inexperienced Stage Excessive College, in Cary, N.C.
Final 12 months Shah had a short lived imaginative and prescient problem, which made a pc display screen practically not possible, even for a short while. After that, whereas visiting household again residence in India, he bought an opportunity to work together with some college students at a college for blind women.
Throughout his interactions with the scholars, he says, he realized they have been decided and pushed and needed to be financially unbiased. None had even thought of a profession in pc programming, nevertheless, believing it to be off-limits due to their visible impairment, he says.
He questioned if there was an answer that might assist blind individuals code.
“How can we redesign and rethink the best way we code in the present day?” he requested himself earlier than devising his AuralStudio. He realized he may put his ardour for coding to good use and created a software program utility for these whose imaginative and prescient impairments are everlasting.
His AuralStudio growth setting permits programmers with a visible incapacity to put in writing, construct, run, and take a look at prototypes.
“All this was constructed towards serving to these with disabilities be taught to code,” Shah says.
It eliminates the necessity for a keyboard and mouse in favor of a customized management pad. It features a voice-only possibility for many who can’t use their palms.
The testbed makes use of Rattle, a programming language that Shah created to be learn aloud, each from the pc and the programmer. AuralStudio additionally makes use of acyclic digraphs to render code, making it simpler and extra intuitive. Shah wrote a two-part autocorrect algorithm to stop homophones and homonyms from inflicting errors. It was performed by integrating AI into the applying.
Shah used the programming languages Rust, C, JavaScript, and Python. Raspberry Pi was the first {hardware}.
He labored with visually impaired college students from the Governor Morehead College of Raleigh, N.C., educating them programming fundamentals.
“The scholars have been so wanting to be taught,” he says. “Attending to see their eagerness, grit, and hard-working nature was so heartwarming and possibly the perfect a part of this mission.”
Shah says he plans to review pc science and enterprise.
“Something I construct could have the tip purpose of bettering the lives of others,” he says.
