college students full design day initiatives


In laboratories and school rooms on the Whiting College of Engineering, college students are finalizing on initiatives they’ve spent numerous hours creating, testing, and perfecting. These designs, introduced in posters, prototypes and demonstrations on the annual occasion generally known as Engineering Design Day on Might 3, signify the fruits of the experiences college students have on the faculty.

This 12 months, greater than 400 college students from all 9 educational departments of the College of Engineering in addition to its Middle for Management Training will take part in a practice that has its roots 38 years in the past, when the Division of Mechanical Engineering launched a capstone design expertise. , After two years in a digital format necessitated by the COVID-19 pandemic, this 12 months’s occasion is being held in individual on campus.

“Design Day is an thrilling milestone in our college students’ journey from learning engineering within the classroom and laboratory to turning into working towards engineers,” says Ed Schlesinger, dean of the Whiting College.

One of many hallmarks of Design Day is that it offers college students the chance to work carefully with school members and scientific researchers from the Johns Hopkins Establishments, in addition to with trade and different sponsors from all through the Mid-Atlantic area.

A have a look at a few of this 12 months’s initiatives:

do not be a drip

It is one in all life’s most deliciously anticipated moments, but in addition the messiest: The burrito (or taco, or gyro, or wrap) is sort of in your mouth when beans and rice and guacamole and salsa fall from the tortilla to the desk — or Worse, your lap.

Impressed by their very own experiences with Messy Lunch, a group of chemical and biomolecular engineering college students have created Tasty Tape, a meals adhesive comprised of a food-grade fibrous scaffold and an natural adhesive that ensures your The popular wrap has the contents tightly packed inside. cooking and consumption.

“First, we discovered concerning the science surrounding tape and numerous adhesives, after which we labored to seek out edible equivalents,” stated Tyler Guarino, who labored with fellow engineering seniors Mary Eric, Rachel Nye and Erin Walsh on the venture. labored collectively.

The group examined a “majority” of substances and combos earlier than selecting the ultimate recipe, which is edible, protected, and has the tensile power you’ll be able to depend on to carry a thick burrito collectively.

As a result of they’re making use of for a patent, the group members refused to reveal their secret formulation.

“What I can say is that every one of its substances are protected to eat, are meals grade, and are widespread meals and dietary components,” Garino stated.

Months spent prototyping resulted in rectangular stripes measuring half an inch by two inches. These keep on with sheets of waxed paper. To make use of, merely take away a strip from the sheet, moisten properly to activate, and apply over your lunch, dinner, or favourite snack. Workforce members put their invention to the take a look at on “too many burrito to depend” however stay assured within the high quality of their product.

“Tasty Tape permits you to have full confidence in your tortilla and revel in your meal, freed from the mess,” Garino stated.

scented elephant

Do you know that elephants have extra odor receptors than canines, and that some scientists consider that pachyderms have a greater sense of scent than another animal? Which means that preserving elephants wholesome entails stimulating their olfactory system. Animal consultants from the Maryland Zoo requested a group of scholars within the Multidisciplinary Engineering Design course on the Middle for Management Training to plan a brand new means to offer sensory enrichment to animals.

The group supplied a easy but elegant answer: a small field outfitted with changeable essential-oil-saturated pads whose scent is pumped into the air by an inside fan, which is activated remotely. Zoo elephant specialists can conceal tools in numerous locations within the animal’s habitat, arousing their curiosity and offering the specified enrichment. With the gadget, college students are offering zoos with “recipes” for dilution of varied scents which might be simpler (much less diluted) or more durable (extra diluted) for animals to detect, relying on their testing with elephants. .

“The venture is a extremely fascinating engineering drawback as a result of we’re designing for primarily two completely different finish customers: the product is for elephants however will probably be utilized by zookeeper. We needed to strike a steadiness between each the elephants and the keepers. gadget,” stated senior Zachary Ellis, who labored on the venture with seniors Sabrina Wang and Iomide Phadip, junior Kyle Velez and sophomore Kaitlyn Bernhard.

The zoo’s oldest feminine elephant, Anna, beloved it when the group loaded peppermint oil into the tools.

“They let Anna scent the mint the identical means you give a canine hen or one thing,” he stated.

dialogue on illness prevention

Annually greater than 1 million folks worldwide die from mosquito-borne ailments corresponding to malaria, yellow fever and Zika. Pesticides work however might be poisonous to people and different animals, and bugs have change into utterly or partially proof against a few of them. Enter traps: tiny units that entice, catch, and kill mosquitoes.

Working with advisors from the Bloomberg College of Public Well being, a group {of electrical} and pc engineering college students have designed and prototyped a solar-powered mosquito internet for areas of the world the place electrical energy just isn’t accessible. Utilizing an onboard photo voltaic panel and battery system, the entice captures daylight and generates the electrical energy wanted to energy its elements, creating mosquito-attracting warmth. As soon as inside, the chemical compounds kill the critters.

“It has been a really rewarding studying expertise,” stated group member and senior Madeline Chabab. “I’ve discovered utterly new abilities, and I’ve already developed abilities. It’s fulfilling to use ECE ideas to a public well being problem, and Dr. Conor McMeneman and Dr. Stephanie from the Bloomberg College of Public Well being Rankin-Turner has been instrumental in creating our information of mosquitoes and the environments with which our gadget will work together.”

Chabab labored the entice with fellow seniors Amanda Fernandes and Karl Urbanik and sophomore Pleasure Ye.

subway slogan

The New York Metropolis subway system is a marvel, transporting greater than 3 million folks every day in a community of 472 stations alongside a route of practically 300 miles. For his Design Day venture, Kulin Sasse determined to discover how one might navigate your entire system within the shortest period of time.

“That is an fascinating drawback as a result of there are a lot of individuals who have tried and achieved a world document by merely making a route by hand. Nonetheless, up to now no critical work has been executed to unravel this computationally.”

“That is an fascinating drawback as a result of there are a lot of individuals who have tried and achieved a world document by merely making a route by hand. Nonetheless, up to now no critical work has been executed to unravel this computationally. I Needed to see if I might make the perfect of my time utilizing completely different computational strategies,” stated Sasse, a first-year double main in utilized arithmetic and statistics and pc science.

They determined to method the issue utilizing metaheuristics, a category of pc code that may resolve massive, complicated issues and might be tailor-made to deal with particular challenges. After a lot work, he got here up with a plan that will allow him to traverse your entire system in 22 hours and 10 minutes. This places him within the putting vary of the newest Guinness World Information time of 21 hours, 28 minutes and 14 seconds (established in 2016 by New York legal professional Matthew Ah, when the system consisted of solely 469 stations).

Sasse is contemplating transferring to NYC this summer time to see how properly his system works in observe.

“I would wish to attempt it in actual life,” stated Sasse.

comfortable trails

A group of seniors from the Division of Environmental Well being and Engineering have been requested by the Associates of Stony Run, the Roland Park Neighborhood Basis, and Firesol to discover a answer to flooding alongside the favored Stony Run Path in northern Baltimore. Components of the walkway get submerged after heavy rains, leading to additional erosion of the trail as pedestrians transfer round muddy spots.

After cautious testing, the group discovered that drainage was drastically affected by the world’s water desk and fewer permeable soil. The issue was exacerbated by runoff from a close-by group. The scholars proposed answer: a detention basin and underdrain that will divert water to a close-by stream.

,[The design process and project were] Good, as a result of we have now to work with the group. It felt extra actual as a result of we have been working with actual folks and fixing an actual drawback,” stated Zachary Ellis, who labored on the venture with Chloe Frantz, Marisela Gomez, Amanda Hinton and Alexander Holt.
