college students full design day tasks

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

This yr, greater than 400 college students from all 9 tutorial departments of the College of Engineering in addition to its Middle for Management Training will take part in a convention 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 yr’s occasion is being held in particular person on campus.

“Design Day is an thrilling milestone in our college students’ journey from learning engineering within the classroom and laboratory to turning into training 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 intently with school members and medical researchers from the Johns Hopkins Establishments, in addition to with business and different sponsors from all through the Mid-Atlantic area.

A have a look at a few of this yr’s tasks:

do not be a drip

It is certainly one of life’s most deliciously anticipated moments, but additionally 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 crew 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 in regards to the science surrounding tape and varied adhesives, after which we labored to search out edible equivalents,” mentioned Tyler Guarino, who labored with fellow engineering seniors Mary Eric, Rachel Nye and Erin Walsh on the undertaking. labored collectively.

The crew examined a “majority” of elements and combos earlier than deciding on the ultimate recipe, which is edible, protected, and has the tensile power you may rely on to carry a thick burrito collectively.

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

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

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

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

scented elephant

Do you know that elephants have extra odor receptors than canine, and that some scientists consider that pachyderms have a greater sense of odor than some other animal? Which means holding elephants wholesome includes stimulating their olfactory system. Animal consultants from the Maryland Zoo requested a crew of scholars within the Multidisciplinary Engineering Design course on the Middle for Management Training to plot a brand new method to offer sensory enrichment to animals.

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

“The undertaking is a extremely attention-grabbing engineering drawback as a result of we’re designing for basically two totally different finish customers: the product is for elephants however will likely be utilized by zookeeper. We needed to strike a stability between each the elephants and the keepers. machine,” mentioned senior Zachary Ellis, who labored on the undertaking with seniors Sabrina Wang and Iomide Phadip, junior Kyle Velez and sophomore Kaitlyn Bernhard.

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

“They let Anna odor the mint the identical method you give a canine hen or one thing,” he mentioned.

dialogue on illness prevention

Annually greater than 1 million individuals worldwide die from mosquito-borne illnesses corresponding to malaria, yellow fever and Zika. Pesticides work however could be poisonous to people and different animals, and bugs have grow to be fully 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 crew {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 isn’t obtainable. Utilizing an onboard photo voltaic panel and battery system, the entice captures daylight and generates the electrical energy wanted to energy its parts, creating mosquito-attracting warmth. As soon as inside, the chemical substances kill the critters.

“It has been a really rewarding studying expertise,” mentioned crew member and senior Madeline Chabab. “I’ve discovered fully new abilities, and I’ve already developed abilities. It’s fulfilling to use ECE ideas to a public well being situation, 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 machine 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 individuals every day in a community of 472 stations alongside a route of practically 300 miles. For his Design Day undertaking, Kulin Sasse determined to discover how one may navigate all the system within the shortest period of time.

“That is an attention-grabbing drawback as a result of there are a lot of individuals who have tried and achieved a world file by merely making a route by hand. Nevertheless, up to now no critical work has been performed to resolve this computationally.”

“That is an attention-grabbing drawback as a result of there are a lot of individuals who have tried and achieved a world file by merely making a route by hand. Nevertheless, up to now no critical work has been performed to resolve this computationally. I Needed to see if I may make one of the best of my time utilizing totally different computational strategies,” mentioned Sasse, a first-year double main in utilized arithmetic and statistics and pc science.

They determined to strategy the issue utilizing metaheuristics, a category of pc code that may clear up giant, complicated issues and could be tailor-made to sort out particular challenges. After a lot work, he got here up with a plan that may allow him to traverse all the system in 22 hours and 10 minutes. This places him within the putting vary of the most recent 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 shifting to NYC this summer season to see how nicely his system works in follow.

“I’d need to strive it in actual life,” mentioned Sasse.

glad trails

A crew of seniors from the Division of Environmental Well being and Engineering have been requested by the Pals of Stony Run, the Roland Park Neighborhood Basis, and Firesol to discover a resolution to flooding alongside the favored Stony Run Path in northern Baltimore. Elements 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 crew discovered that drainage was tremendously affected by the realm’s water desk and fewer permeable soil. The issue was exacerbated by runoff from a close-by neighborhood. The scholars proposed resolution: a detention basin and underdrain that may divert water to a close-by stream.

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