Shake tables provide a critical tool for simulating earthquake events and testing the response of structures to seismic forces. Simulated earthquake conditions can help civil engineers identify potential weaknesses in the design and suggest ways to improve a structure’s resilience. In a controlled laboratory setting, shake tables can also be...

Background Real-time immediate feedback is known to enhance learning by providing better engagement with learners, as seen in a classroom environment with teachers. Applications with automated feedback are designed to mimic the prompt feedback provided by teachers in a classroom. Advances in artificial intelligence (AI) technology have enabled this...

Background Modern infrastructure combines numerous interdependent systems including power, water, and cyber. These systems are often designed in isolation but necessarily interact in practice. Such interactions make it challenging to identify and quantify vulnerabilities using engineering practices specific to individual disciplines. This challenge...

Background By integrating visual stimuli with perceived tactile sensation, mixed-reality haptic devices provide a critical dimension to otherwise intangible virtual content. Much of the commercial and academic efforts in this domain have focused on delivering simulated interactions with rigid objects, often through the use of vibrotactile gloves, robotic...

Loop-mediated isothermal amplification (LAMP) has great potential for sensitive and selective nucleic acid analysis in resource-limited settings. Amplifications can be easily observed via optical means such as colorimetry which combines robust performance and simple instrumentation. To date, microfluidic approaches based on colorimetric detection have...

There are approximately two million people, in the US alone, suffering from limb loss and another 185,000 new limb loss cases each year. Upper limb prosthetics are typically categorized into body-powered and electric style systems. Body-powered systems lack feedback, cannot provide high force output and can be fatiguing. Electric systems are expensive,...

Multi-Axis Robotic Platform for Studying Neuromechanics of an Ankle Joint SI Case No. M17-209P Background The human ankle provides a variety of functions during both walking and standing. The ankle generates propulsion, supports body weight, absorbs impact, contributes to balance, and aids in stability among a number of other functions through...

Capturing carbon dioxide from open air to minimize harmful emissions becomes less effective with lower carbon dioxide concentration. To address this, scientists use moisture swing sorbents which are chemicals that bind to carbon dioxide in dry environments and release it when exposed to moisture. Metal-organic frameworks (MOFs) contain a metal and a...

Your posture is an important factor in proper and comfortable walking and can result in easier breathing and less back pain. It is also paramount in rehabilitation, especially for patients suffering from neural trauma. Having good posture does not come easily though, and training the body to walk properly (whether it is for pain relief or rehabilitation)...

Terrorism has become a pervasive global problem. The most popular devices used by terrorists are improvised peroxide explosives. These devices are constructed from common chemicals that are readily available all over the world and are also very inexpensive to purchase. Additionally, it is very difficult to detect these devices because there are so many...
