Coral reefs are important to marine ecosystems, supporting extra species than every other ocean setting. Greater than 80 p.c of the planet’s coral reefs have been bleached because of rising ocean temperatures and air pollution, in line with the U.S. Nationwide Oceanic and Atmospheric Administration. The reef injury threatens marine biodiversity throughout the globe.
Highschool pupil Sydney West constructed a remotely operated car (ROV) designed to assist protect and maintain coral reefs. West, a graduate of Hanford Excessive in Richland, Wash., and an incoming freshman on the College of Hawai’i at Manoa, plans to pursue a level in mechanical engineering.
Her venture, The Design and Engineering of an Clever Remotely Operated Car for Coral Reef Analysis and Monitoring, was showcased in Could at Regeneron’s Worldwide Science and Engineering Truthful, held in Columbus, Ohio.
West gained this yr’s IEEE Presidents’ Scholarship of US $10,000 for her underwater car, Cnidaria. The award is payable over 4 years of undergraduate college examine and features a complimentary IEEE pupil membership. Ramy Tantawy, chair of the IEEE Columbus Part, introduced West with the scholarship.
The IEEE Basis established the Presidents’ Scholarship to acknowledge a deserving highschool pupil whose venture demonstrates an understanding of electrical engineering or one other IEEE area of curiosity. The scholarship is run by IEEE Instructional Actions.
The second-place winner acquired a $600 scholarship; the third-place winner acquired a $400 scholarship. Each additionally received complimentary IEEE pupil memberships.
Pc imaginative and prescient and sensors determine coral species
The ROV’s title, Cnidaria, comes from the taxonomic household title for coral species. When discussing the venture, West affectionately refers back to the drone as “she,” a nod to the nautical custom of personifying vessels, in addition to a mirrored image of the deep connection and delight she feels for her work.
Cnidaria is provided with pc imaginative and prescient know-how, conductivity, temperature and depth sensors, and a water-sampling system. The car is able to figuring out quite a lot of coral species, detecting anomalies amongst them, gathering water samples, and logging knowledge concerning the water’s situation.
West describes the ROV as versatile. “Every of her techniques will be modified, indifferent, or changed simply,” she says. The car will be personalized for various analysis wants.
“By no means be afraid of failing. Failing shouldn’t be the tip. When you’re not failing, you’re not studying.”—Fay Salim al-Mahrouqi
West plans so as to add a data-logging system and a navigational support, a Doppler velocity log, to assist researchers extra precisely observe coral places and streamline knowledge assortment.
“I would like her to be a software for all researchers who examine coral to enhance their effectivity, and make it simpler for them to give attention to their analysis and never have to fret about all the labor-intensive and logistical hassles,” West says.
West intends to launch a enterprise providing companies for ROV customers, together with refurbishing the drones, promoting components and techniques, and providing coaching programs to those that wish to construct their very own marine automobiles.
After finishing her bachelor’s diploma in mechanical engineering, she plans to attend graduate college to review marine biology.
“I wish to get the very best of each worlds,” she says. “Having information concerning the ideas of engineering, and in addition what I’m engineering for, will assist me strengthen my work within the area.”
West advises budding engineers to domesticate tenacity.
“Issues will go flawed,” she says. “You’ll hit roadblocks and obstacles, and spend days or even weeks attempting to unravel a single downside, however that constant effort and willpower are key to eventual success.”
Fay Salim al-Mahrouqi, a highschool senior on the Dohat al-Adab Faculty in Muscat, Oman, took second place for her venture, A Hybrid Studying-Pushed Method for Lung Enhancement, Tumor Detection, and Fibrosis System.
Al-Mahrouqi’s inspiration stemmed from the lack of her grandfather to idiopathic pulmonary fibrosis. IPF is a continual illness that develops when lung tissue turns into too thick, inflicting everlasting scarring within the lungs, in line with the U.S. Nationwide Coronary heart, Lung, and Blood Institute. The situation makes it exhausting to breathe. Regardless of quite a few hospital visits and CT scans, her grandfather was recognized with the situation too late, main al-Mahrouqi to wish to enhance IPF analysis strategies.
“Radiologists search for issues like tiny, honey-shaped complicated websites or faint, hazy areas known as ground-glass opacities within the lungs,” al-Mahrouqi says. “These identical patterns additionally present up in different ailments, like nonspecific interstitial pneumonia and early-stage lung most cancers. This usually results in a misdiagnosis.”
She developed a hybrid synthetic intelligence system that makes use of a contrast-limited adaptive histogram equalization course of, enhancing CT photos by amplifying distinction and limiting picture grain. Her prototype additionally makes use of six totally different pretrained convolutional neural networks that classify fibrosis patterns and nodule sorts—malignant, benign, or regular—to offer an earlier analysis.
“This prototype is exclusive as a result of it converts classification and enhancement right into a single diagnostic software,” al-Mahrouqi says. She says it’s the first time machine studying methods have been used to focus on fibrosis patterns.
She is collaborating with hospitals to gather extra affected person knowledge to assist her enhance the accuracy of her diagnostic software.
Al-Mahrouqi says she is dedicated to advancing her venture: “The method of inventing one thing shouldn’t be about coming into a contest. It’s about fixing real-world issues. What’s the purpose of engaged on a venture in case you are not prepared to proceed to develop it?”
She says she hopes to launch a startup to commercialize her know-how, with the objective of reaching worldwide adoption by hospitals. Within the meantime, she says, she plans to dedicate her senior yr to finding out entrepreneurship and can pursue a level in knowledge science, cybersecurity, or electrical engineering.
Her recommendation to younger engineers is: “By no means be afraid of failing. Failing shouldn’t be the tip. When you’re not failing, you’re not studying.”
A stethoscope to determine a number of physique sounds
Kayley Xu, a junior on the Bishop’s Faculty in La Jolla, Calif., took third place for her Wearable Stethoscope Array for Cardiopulmonary Sound Localization and Interference Suppression Utilizing Beamforming venture.
When Xu was 13 years previous, she had a extreme case of pneumonia. “In the course of the analysis and remedy course of, I noticed limitations with a few of the medical gear, such because the stethoscope,” she says.
That have impressed her to pursue respiratory illness analysis, particularly the efficiency of auscultation: listening to the physique’s inner sounds.
Via her analysis, she found that conventional stethoscopes have limitations together with a health care provider’s incapacity to hearken to a number of sounds concurrently—which creates interference after they overlap.
Xu designed a chest piece utilizing a versatile printed circuit board that conforms to the affected person’s physique. The piece makes use of a microelectromechanical microphone able to capturing a variety of frequencies. By combining novel {hardware} designs with beamforming—a sign processing method—Xu says the machine “can seize each low- and high-frequency vary sounds corresponding to lung crackles and coronary heart murmurs, which are sometimes missed by standard stethoscopes.”
The sensor in her machine detects the place a sound is coming from extra precisely with out sacrificing audio high quality. The machine is also extra reasonably priced than a regular stethoscope, she says, as its versatile printed circuit board will be produced for lower than US $1 per unit when manufactured at scale.
“I hope my machine will allow extra underdeveloped areas world wide to have broader entry to stethoscopes and cheaper processes,” she says.
Her venture not solely helped her advance her technical expertise but in addition taught her the significance of perseverance, creativity, and innovation, she says.
As she heads into her junior yr of highschool, she plans to proceed growing her machine. She additionally intends to pursue an engineering diploma.
Her recommendation to younger engineers? “Have a whole lot of grit and perseverance.”
