Drowning is the third main reason for unintentional deaths globally, in line with the World Well being Group. The deaths disproportionately impression 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 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 Could at Regeneron’s Worldwide Science and Engineering Truthful (ISEF) in Los Angeles.
Kim mission took first place on this yr’s IEEE Presidents’ Scholarship competitors: a prize of US $10,000 payable over 4 years of undergraduate college research. 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 area 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 little one.
“I’ve been decided to seek out methods to create a safer group utilizing know-how my entire life,” she says. “I spotted as I bought 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 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 sorts 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 route 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 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 wished to be part of.”
She introduced her mission at two IEEE gatherings this yr: the IEEE Worldwide Convention on Management and Automation and the IEEE Worldwide Convention on Automated Management and Clever Techniques.
Kim says among the roadblocks she encountered along with her mission have made her a greater engineer.
“If all the things goes completely, then there won’t be a lot to be taught,” she says. “However in the event you fail—like by accident flying your drone into your dad and mom’ home, like I did—you get alternatives to be taught.”
She plans to check electrical or mechanical engineering in faculty. Ultimately, she says, she want to construct and mass-produce applied sciences that assist communities at a low price.
Recognizing carbon dioxide in soil

Extreme carbon dioxide is a number one trigger of worldwide warming and local weather change, in line with NASA. Burning fossil fuels is a distinguished supply of carbon dioxide, nevertheless it additionally will be launched from the bottom.
“Individuals 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 might account for 80 % of web ecosystem carbon alternate.”
Busulu is a senior on the Foundation Impartial highschool in Fremont, California.
Ecosystem carbon alternate is the switch of carbon dioxide between the environment and the bodily surroundings. As a result of the alternate will not be typically accounted for, there’s a spot in information. To supply extra 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 accommodates 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 methodology, which measures flux utilizing Fick’s regulation, 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 gives real-time information by 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 world perspective.
Bulusu got here up along with her concept with assist from mentors and professors Helen Dahlke and Elad Levintal.
“They instructed 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’d be so passionate a couple of mission. I 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 mission, and it has come up to now.”
Bulusu plans to pursue a level in pc 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 mission.
Accessible communication for ALS sufferers

Xiangzhou “Jonas” Solar has been volunteering to assist folks with amyotrophic lateral sclerosis, often known as Lou Gehrig’s illness. After Solar and his household frolicked serving to ALS sufferers and helping caretakers in Hong Kong and the USA, he was impressed to create a cell app to help them. He’s a senior on the Webb College of California, in Claremont.
Whereas volunteering, he seen that ALS sufferers had hassle speaking due to the illness.
“ALS damages neurons within the physique, and sufferers step by step lose the power to stroll, transfer their fingers, and converse,” he says. “My goal with Gaze Hyperlink was to construct a cell 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 folks with disabilities linked to ALS to make use of their telephone’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 included.
Solar’s ardour for his mission is palpable.
“My favourite second was after I introduced a prototype of Gaze Hyperlink to a caretaker from the ALS Affiliation, and so they 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 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 folks with disabilities. He’s keen about design and visible arts as effectively, and says he hopes to mix them together with his engineering abilities.
Gaze Hyperlink is on the market by Google Play.
An inclusive technique 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 yr Shah had a short lived imaginative and prescient challenge, which made taking a look at a pc display practically not possible, even for a short while. After that, whereas visiting household again house in India, he bought 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 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 puzzled if there was an answer that might assist blind folks code.
“How can we redesign and rethink the way in which we code in the present day?” 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 utility for these whose imaginative and prescient impairments are everlasting.
His AuralStudio improvement surroundings permits programmers with a visible incapacity to write down, construct, run, and check 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 choice for many who can not use their fingers.
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 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., instructing 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 very best a part of this mission.”
Shah says he plans to check pc science and enterprise.
“Something I construct can have the top aim of bettering the lives of others,” he says.
