Drowning is the third main reason behind unintentional deaths globally, in keeping with the World Well being Group. The deaths disproportionately influence low- and middle-income communities, whose seashores are likely to lack lifeguards due to restricted funds. Final yr 104 drownings of the 120 reported in the USA occurred on unstaffed seashores.
That fueled Angelina Kim’s drone undertaking. 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 undertaking was showcased in Might at Regeneron’s Worldwide Science and Engineering Honest (ISEF) in Los Angeles.
Kim undertaking took first place on this yr’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 undertaking demonstrates an understanding {of electrical} or electronics engineering, pc science, or different IEEE discipline of curiosity. The scholarship is run by IEEE Instructional Actions.
Kim has lengthy been motivated to assist these in want, particularly after her mom’s sickness when Kim was a younger little one.
“I’ve been decided to search 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 undertaking 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 forms of drones: a scout craft and a rescue craft. The scout drone surveys roughly 1 kilometer of shoreline, taking images 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 course a wave is shifting. The algorithm detects rip currents and, utilizing the depth-risk mannequin, focuses on sturdy 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 gadget outfitted with a heaving rope and may 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 course 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 undertaking at two IEEE gatherings this yr: the IEEE Worldwide Convention on Management and Automation and the IEEE Worldwide Convention on Computerized Management and Clever Programs.
Kim says among the roadblocks she encountered along with her undertaking have made her a greater engineer.
“If all the things goes completely, then there is not going to be a lot to study,” she says. “However for those who fail—like by chance flying your drone into your mother and father’ home, like I did—you get alternatives to study.”
She plans to review electrical or mechanical engineering in school. Finally, she says, she wish 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 worldwide warming and local weather change, in keeping with NASA. Burning fossil fuels is a distinguished supply of carbon dioxide, but it surely additionally will be launched from the bottom.
“Individuals 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 may account for 80 p.c of web ecosystem carbon change.”
Busulu is a senior on the Foundation Unbiased highschool in Fremont, California.
Ecosystem carbon change is the switch of carbon dioxide between the environment and the bodily atmosphere. As a result of the change is just not typically accounted for, there’s a spot in knowledge. To offer further data, 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 incorporates three important subunits: a flux chamber, an under-soil sensor array, and a microcontroller with a knowledge 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 methodology, which measures flux utilizing Fick’s legislation, wanting on the CO2 gradient within the soil, and multiplying it with the soil diffusivity coefficient. Sensors are put within the floor at totally different depths to measure the gradient.
“Carboflux makes use of the gasoline focus between the depths to foretell what the soil carbon flux could be,” Bulusu says.
The system is automated and offers real-time knowledge by way of microcontrollers and a modem. The gadget research soil flux, each above and beneath the bottom, she says.
“It is ready to be scaled regionally and globally,” she says, “serving to to pinpoint native carbon sources and carbon sinks.” The info additionally may give scientists a large-scale international perspective.
Bulusu got here up along with her thought with assist from mentors and professors Helen Dahlke and Elad Levintal.
“They informed me concerning the lack of worldwide carbon flux knowledge, and the concept for a community of CO2 flux sensors,” Bulusu says. “This knowledge is required for local weather modeling and mitigation methods.
“I didn’t suppose I’d be so passionate a couple of undertaking. I really like science, however I by no means thought I’d be somebody who would sit within the rain and chilly for hours making an attempt to determine an issue. I used to be so invested on this undertaking, and it has come to date.”
Bulusu plans to pursue a level in pc science or environmental science. No matter discipline she choses, she says, she needs to enhance the atmosphere with the expertise she creates.
She was awarded a $600 scholarship for her undertaking.
Accessible communication for ALS sufferers

Xiangzhou “Jonas” Solar has been volunteering to assist individuals with amyotrophic lateral sclerosis, also referred to as Lou Gehrig’s illness. After Solar and his household hung out serving to ALS sufferers and aiding caretakers in Hong Kong and the USA, 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 converse,” he says. “My goal with Gaze Hyperlink was to construct a cellular software that would 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 technology, 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 undertaking 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 accomplishment that I might 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 effectively, and says he hopes to mix them together with his engineering expertise.
Gaze Hyperlink is accessible by way of Google Play.
An inclusive method to code
Abhisek Shah’s AuralStudio offers a means for programmers with visible impairments to code utilizing the Rattle language he wrote, which will be learn aloud.Lynn Bowlby
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 yr Shah had a short lived imaginative and prescient concern, which made taking a look at a pc display screen practically inconceivable, even for a short while. After that, whereas visiting household again dwelling in India, he bought an opportunity to work together with some college students at a faculty for blind ladies.
Throughout his interactions with the scholars, he says, he realized they have been decided and pushed and needed to be financially impartial. None had even thought of a profession in pc programming, nonetheless, believing it to be off-limits due to their visible impairment, he says.
He puzzled if there was an answer that would assist blind individuals code.
“How can we redesign and rethink the best way we code right this moment?” he requested himself earlier than devising his AuralStudio. He realized he might put his ardour for coding to good use and created a software program software for these whose imaginative and prescient impairments are everlasting.
His AuralStudio growth atmosphere permits programmers with a visible incapacity to jot down, construct, run, and check prototypes.
“All this was constructed towards serving to these with disabilities study 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 individuals 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 forestall homophones and homonyms from inflicting errors. It was finished by integrating AI into the appliance.
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 desirous to study,” he says. “Attending to see their eagerness, grit, and hard-working nature was so heartwarming and doubtless the perfect a part of this undertaking.”
Shah says he plans to review pc science and enterprise.
“Something I construct may have the top aim of bettering the lives of others,” he says.
