Glaucoma is a group of eye conditions characterized by damage to the optic nerve, which transmits visual information from the eye to the brain. The cause is elevated intraocular pressure (IOP). Often referred to as the “silent thief of sight,” it can lead to progressive vision loss with no early…

Online learning is on the upswing, owing to the unique opportunities it provides to many kinds of learners. At Purdue, for example, enrollment in credit-bearing and professional development engineering online programs has quadrupled over the past five years. …

Smart grid refers to the use of information technology to make the power grid “smart.” For example, we can use sensors and communication infrastructure to monitor the voltages and currents in different locations of the grid for more precise control. In addition, a smart grid enables dynamic pricing of electric…

“Uncertainty is the only certainty there is, and learning how to live with insecurity is the only security,” American mathematician John Allen Paulos wrote in his book A Mathematician Plays the Stock Market. Uncertainties abound everywhere, and come from myriad sources. …

Construction engineering and management is an oft-overlooked competency that is rising in prominence as we confront the enormous infrastructure rebuild needs of the United States and advance green-building strategies for a sustainable future. Theodore “Ted” Weidner is an experienced hand in the field, with decades as a facilities and construction…

Aging infrastructure is a worldwide challenge, and the United States is no exception. The 2021 report card from the American Society for Civil Engineering (ASCE) gave America’s infrastructure a C- for condition and performance. This poor grade is the result of an infrastructure that continues to deteriorate with age, increased…

Now more than ever — though perhaps every generation says that — we need tools to help us make sense of this world. Sensemaking is one of those tools, and we most often need it when our understanding of the world becomes unintelligible in some way. We need sensemaking when…

Every unruly environment needs someone to keep tabs on all the comings and goings, like the hall monitors who are ubiquitous in schools. But while the corridors and movements inside a school are bounded and relatively easy to chart, the great hall of space — in its cosmic vastness, large…

Used to be, getting to another planet was a wild dream. Now we’re talking about living on one. That’s going to require autonomous transformable systems — shape shifters — in future space missions. These multipurpose systems will meet the needs of the rapidly-growing space domain business. They can provide more…
