Engineering in harmony | MIT News

How does an ensemble enjoy audio collectively although apart? This was the problem dealing with Frederick Ajisafe and the relaxation of the MIT Wind Ensemble (MITWE) at the start out of the Covid-19 pandemic. A person process was to independently document tracks that were later combined together to sound like a entire ensemble.

“It was a odd working experience,” states Ajisafe, who performs the tuba and is pursuing a double important in aerospace engineering and audio. “It was not as cohesive as actively playing with each other in individual, but the outcomes are some thing to be proud of.”

Now that the team is capable to rehearse in particular person after once more, Ajisafe has a renewed appreciation for the community he has found in just MITWE.

“As considerably as the togetherness of the ensemble, the intangible and social connections that we all have, I truly feel like we’re back in that perception,” he suggests. “The greatest variance is that I’m a senior. The very last time we were being with each other with out masks, I was a freshman wanting up to individuals, but now men and women are wanting up to me.”

An accomplished musician, Ajisafe has been taking part in the tuba due to the fact center university.

“In center college, I listened to a whole lot of items like ‘music makes you smarter,’ so I claimed, ‘okay, I want to be smarter,’ so I joined the band application,” says Ajisafe. “Something about my lip shape and my lung capacity was seriously excellent for the tuba.”

It was a lot more than just a physical affinity for the instrument that saved Ajisafe taking part in he also cherished the social aspect of enjoying in an ensemble. Last yr, he was acknowledged as an Emerson Scholar in tuba effectiveness, acquiring sponsored non-public lessons with renowned professional tuba player Ken Amis.

Ajisafe has also taken a selection of lessons in MIT’s Music and Theater Arts area that include a wide vary of matters, from regular concept to composition.

A single of his beloved classes is 21M.361 (Electronic New music Composition), which teaches how to sample and manipulate sounds in various software package. Some of the seems Ajisafe sampled in the course of the training course of the course include snapping, clapping, participating in a scale on his tuba, and slamming an object on the floor. Then, all those appears had been in shape to a rating Ajisafe developed for a previous assignment. He explained the process as intellectually fulfilling, as properly as pushing the envelope in how he understands tunes.

“Most folks possibly would not phone it audio, but it has musical things,” says Ajisafe. “It presents you a new viewpoint on the planet.”

From spelling bees to organic language processing

Ajisafe grew up in Orlando, Florida, and experienced a broad array of passions growing up.

“Whatever they were training in school, I was excited about,” he says. “I was often interested in phrases and items like that, but I was also intrigued in science and math.”

Escalating up shut to NASA’s Kennedy Area Centre, it is quick to see how Ajisafe cultivated an interest in aerospace.

“Aerospace engineering is the most exciting subject in engineering correct now,” claims Ajisafe. “And you can see it with all of the stuff likely on in Florida. Viewing all the rocket launches influenced me to decide on aerospace engineering and when I obtained into it, it confirmed that much more and a lot more.”

But there was also a childhood participation in the regional spelling bee that tickled his desire in terms. Now, he’s doing work on a undertaking, by means of MIT’s Undergraduate Study Alternatives Method, that combines linguistics, purely natural language processing, and aircraft design and style needs.

1 of the issues of producing style and design demands for aircraft is ambiguity, primarily when the demands are published in common, normal language form. Additional engineers are turning to model-based mostly devices engineering requirements, which is more recent and a lot more formalized. Ajisafe is tackling the difficulty of translating the authentic demands into the more recent type, precisely, placing alongside one another agent instruction facts for a equipment discovering algorithm.

“I’m figuring out the extra granular stage to label these kinds of sentences to determine out if we could use a a lot more computerized method using elements of speech,” Ajisafe points out. “For illustration, probably you can devise a pattern that labels a noun at the commencing of a sentence as the entity critical to methods engineers, like ‘the parachute shall deploy at this time’ — the parachute is the entity.”

Alternatively of changing each and every element of the sentence to a process product, his crew has established that it is effective to concentration on labeling and extracting sure critical aspects.

The undertaking combines many unique techniques that Ajisafe has picked up in the course of his MIT career, all coming with each other in harmony to deal with a exclusive problem.

“I usually want to see the upcoming thing beyond”

Future 12 months, Ajisafe ideas to go after his master’s degree by means of the Office of Aeronautics and Astronautics.

“Ultimately, I would like to be operating with the technological problems linked to place exploration and acquiring humanity to the stars,” suggests Ajisafe. “I don’t know precisely where I match in that, but with any luck , I can have a positive effect.”

And of system, like it is been all through his daily life, he desires to carry on accomplishing songs, no matter if it be participating in tuba or hoping other shops.

“For humanity to survive, it is good and perhaps even required to request out other destinations aside from Earth,” Ajisafe suggests with regards to his profession aspirations. But, it connects to how he techniques his personalized existence as nicely: “I usually want to stroll out someplace I have by no means been right before and be in a spot that I’m fully unfamiliar with. I always want to see the up coming issue outside of.”
