Drowning is the third main reason behind unintentional deaths globally, in response to the World Well being Group. The deaths disproportionately influence 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 the US occurred on unstaffed seashores.
That fueled Angelina Kim’s drone challenge. Kim is a senior at the Bishop’s Faculty in La Jolla, Calif. Her Autonomous Unmanned Aerial Automobile (UAV) System for Ocean Hazard Recognition and Rescue: Scout and Rescue UAV Prototype challenge was showcased in Could at Regeneron’s Worldwide Science and Engineering Honest (ISEF) in Los Angeles.
Kim challenge 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 scholar whose challenge demonstrates an understanding {of electrical} or electronics engineering, laptop science, or different IEEE area 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 baby.
“I’ve been decided to search out methods to create a safer group utilizing know-how my complete life,” she says. “I noticed as I obtained extra into robotics that know-how can be utilized to guard these in my group.”
Kim and the second- and third-place scholarship winners additionally obtained a complimentary IEEE scholar membership.
As well as, to mark the scholarship’s quarter century, IEEE established a twenty fifth anniversary award to honor a challenge that’s prone 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 varieties 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 path a wave is transferring. 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 machine 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 path 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 wished to be part of.”
She introduced her challenge 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 Programs.
Kim says a few of the roadblocks she encountered along with her challenge have made her a greater engineer.
“If the whole lot goes completely, then there won’t be a lot to study,” she says. “However if you happen to fail—like by accident flying your drone into your dad and mom’ home, like I did—you get alternatives to study.”
She plans to check electrical or mechanical engineering in faculty. Ultimately, 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 response to NASA. Burning fossil fuels is a distinguished supply of carbon dioxide, however it additionally will be launched from the bottom.
“Folks don’t account for the big 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 % 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 surroundings. As a result of the trade shouldn’t be typically accounted for, there’s a spot in information. To supply 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 comprises three important 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 totally 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 machine 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 world perspective.
Bulusu got here up along with her thought with assist from mentors and professors Helen Dahlke and Elad Levintal.
“They informed me in regards to the lack of worldwide 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 assume I might be so passionate a few challenge. I really like science, however I by no means thought I might 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 challenge, and it has come up to now.”
Bulusu plans to pursue a level in laptop science or environmental science. No matter area she choses, she says, she needs to enhance the surroundings with the know-how she creates.
She was awarded a $600 scholarship for her challenge.
Accessible communication for ALS sufferers

Xiangzhou “Jonas” Solar has been volunteering to assist folks 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 the US, he was impressed to create a cellular app to help them. He’s a senior on the Webb Faculty 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 regularly lose the flexibility to stroll, transfer their arms, and converse,” he says. “My goal with Gaze Hyperlink was to construct a cellular software 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 technology, and text-to-speech capabilities to permit folks with disabilities linked to ALS to make use of their cellphone’s front-end digital camera 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 characteristic is integrated.
Solar’s ardour for his challenge is palpable.
“My favourite second was after 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 obtained a $400 scholarship for putting third.
He says he plans to make use of his engineering know-how to assist folks with disabilities. He’s keen about design and visible arts as properly, and says he hopes to mix them along with his engineering abilities.
Gaze Hyperlink is on the market 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 Degree Excessive Faculty, in Cary, N.C.
Final 12 months Shah had a brief imaginative and prescient challenge, which made a pc display almost not possible, even for a short while. After that, whereas visiting household again dwelling in India, he obtained an opportunity to work together with some college students at a college for blind ladies.
Throughout his interactions with the scholars, he says, he realized they have been decided and pushed and wished to be financially impartial. None had even thought-about a profession in laptop programming, nonetheless, believing it to be off-limits due to their visible impairment, he says.
He questioned if there was an answer that might assist blind folks code.
“How can we redesign and rethink the way in which we code at the moment?” 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 software for these whose imaginative and prescient impairments are everlasting.
His AuralStudio improvement surroundings permits programmers with a visible incapacity to put in writing, 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 many who can not use their arms.
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 carried out 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 Faculty of Raleigh, N.C., instructing 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 most effective a part of this challenge.”
Shah says he plans to check laptop science and enterprise.
“Something I construct could have the tip aim of enhancing the lives of others,” he says.
