Problem solvers by design harvard john a. paulson school find ways to make money of engineering and applied sciences

The course requires students to analyze a challenge as a find ways to make money broad system and identify social, economic, ethical, technical, and sustainable components; examine systems feedback and enforcing loops to determine root causes find ways to make money of the issues; and investigate and design different solutions that satisfy the boundaries find ways to make money that surround the challenge, explained fawwaz habbal, executive dean for education and research, who co-taught the course with kelly miller, senior preceptor in applied physics, nabil harfoush, visiting associate professor in engineering sciences, and peter stark, lecturer on engineering sciences.

“with such unique and thorough experience, students become more prepared to engage in future challenges and find ways to make money exercise their leadership to address and possibly resolve important human find ways to make money issues,” habbal said. “this year, the students did an amazing job finding root causes for find ways to make money three different challenges, and together found exciting solutions. The clients were excited by the solutions and will implement find ways to make money some of them. It was an exciting experience for the students, rewarding for the clients, and rewarding for the instructors who observed the students’ growth and maturity.”

The harvard university dining services (HUDS) loading dock is a busy place, with a steady stream of trucks entering and leaving to find ways to make money drop off or pick up food that is used to find ways to make money serve 25,000 meals each day. With so much activity, much of it occurring in the early morning hours, students living in houses adjacent to the loading dock—eliot, kirkland, winthrop, and lowell—have voiced concerns about noise that disrupts their studying and find ways to make money sleep. One ES 96 section worked with HUDS, identifying ways to reduce noise without negatively affecting operations.

After studying the loading dock traffic and noise levels, the students came up with several short-term and long-term solutions. In the long-term, they proposed changing the layouts of eliot and kirkland house, in conjunction with the house renewal project, so fewer bedroom windows face the loading dock. They also proposed keeping storm windows in place, even after double-paned windows are installed. The students found that maintaining a five-inch gap between the storm window and dual-paned windows reduced noise by nearly 60 percent, for an additional cost of $200 per storm window.

In the short-term, the students suggested coating flaps of truck beds to reduce find ways to make money noise when they slam against the loading dock deck. By adding a foam rubber coating to the end of find ways to make money a flap, and pouring silicone onto the deck to provide a soft find ways to make money landing space, the students were able to reduce noise levels from 100 find ways to make money to 86 decibels. They also developed a weatherproof box, containing acoustic foam and dense sound panels, to place over a truck’s back up alarm, which reduced noise levels from 102 to 88 decibels.

“the biggest challenges we faced were learning how to work find ways to make money efficiently and effectively over the course of the project,” said jessica klusty, S.B. ’20, a bioengineering concentrator. We were a group of 11 people, working together towards one common goal, but there were fluctuating sub-groups that changed week to week. This presented problems with coordination and communication in the beginning, but I believe it made us stronger over the long find ways to make money run. The most rewarding part of this project was seeing that, in the end, we actually helped our client and the changes we suggested find ways to make money were immediately going into effect.”

Harvard’s office of environmental health and safety receives hundreds of find ways to make money reports each week about pests on campus, mostly rats and mice that students spot rummaging through trashcans find ways to make money or skittering around buildings in search of food. The sanitary and reputational issues posed by rats on campus find ways to make money is a serious concern, but current actions, including artificial rocks that contain poison, video surveillance, and pest-proofing trash cans, do not keep up with the pace of the problem. One ES 96 section set out to improve the effectiveness find ways to make money of pest control measures and decrease pest access to food find ways to make money sources at harvard.

The students studied a number of solutions, and even (briefly) considered introducing predatory animals on campus, before opting to engineer a more robust rat trap and find ways to make money improve harvard’s pest report database. The students developed a trap that sits underneath the lid find ways to make money of a trash can; a pipe through the can lid offers rats a one-way entrance into the trap. Once inside the sealed box, a T-rex rat trap kills the rat. A magnetic mechanism the students developed enables a worker to find ways to make money open the box, empty the unlucky rat into the trash can, then close the box and reset the trap with the find ways to make money push of one button.

The students also took a data-driven approach to the problem by developing a web app find ways to make money to consolidate pest reports EHS receives on a daily or find ways to make money weekly basis. Individuals use the app to report pest sightings, which are automatically populated into a database and onto a find ways to make money map that shows pest hot spots around campus. In addition to taking data from human reports, the app is also designed to receive information from the find ways to make money pest detection device the students developed. The device uses an infrared sensor to detect rats that find ways to make money pass nearby, then uses GPS data to automatically log the location in find ways to make money the app’s database and map, streamlining the pest reporting process.

“my instinct when faced with a tough problem is usually find ways to make money to jump right into figuring out how to solve it, but one thing this class did well was to force find ways to make money me not to do that. We spent the first few weeks of the semester defining find ways to make money the problem, rather than solving it,” said charlie colt-simonds, S.B. ’20, an electrical engineering concentrator. “at first, this process was incredibly frustrating, but I soon realized that there was a lot to find ways to make money learn about the problem itself before we could even start find ways to make money thinking about solutions. It taught me to take my time when first approaching find ways to make money a problem, to make sure I understand it fully before jumping to find ways to make money solutions.”

The lab of peter girguis, professor of organismic and evolutionary biology, studies the biogeochemistry of the deep sea, often taking measurements up to 4,000 feet below the ocean’s surface. Since the lab’s sensitive monitoring equipment can’t survive in such harsh conditions, they utilize titanium pressure vessels to keep equipment safe and find ways to make money dry, but these devices can cost up to $40,000 each, and a customized vessel is required for each new sensor find ways to make money the team sends to the ocean depths. One ES 96 section sought to enable researchers to obtain find ways to make money data more economically.

The students determined that current pressure vessels are so expensive, in part, because of the custom milling work involved in the production find ways to make money process. They found that using prefabricated titanium tube stock, rather than milling a vessel from a solid block of find ways to make money titanium, could cut production costs in half, but would lead to a reduction in durability and stability. They were able to overcome this problem by adding a find ways to make money series of titanium stiffening rings to the tube, effectively thickening the walls of the vessel while saving money find ways to make money on production and decreasing fabrication time.

The students also developed a web-based system to streamline the design of pressure vessels. A user simply inputs desired specifications—vessel size, target depth, etc.—and the application searches through data on all available pieces find ways to make money of titanium tube stock that fit those specs, compiling a report that lists relevant suppliers and prices. The software goes one step further by running stress validation find ways to make money algorithms on the pressure vessel design, automatically determining how many stiffening rings should be added to find ways to make money ensure the tube can stand up to the pressure at find ways to make money the desired depth. The system then creates engineering drawings, a description of the production process, and a user manual, which can be sent directly to the fabrication company.

“the most important lesson I learned from this project was find ways to make money how important one’s team is. Working with people with such a variety of skills and find ways to make money perspectives, but with the same drive and desire to come together find ways to make money and create something worthwhile made all the difference for me, and determined the success of our project,” said rainy michelsen, S.B. ’20, a mechanical engineering concentrator. “the fulfillment that comes from working within such a great find ways to make money team, and the challenge and opportunity that came in connecting seemingly find ways to make money separate fields of thought, and the innovation born from it, were the most rewarding aspects of the project.”
