Current 3D printing systems do not provide a method for various materials to be simultaneously deposited… more
Abstract:Balance disorders have a large negative impact on quality of life. Several methods have been developed that can help patients stay balanced, however these systems at present remain tethered to a gait lab or to a balance platform. A real time system that calculates the center of pressure and… more
Abstract:A sensor for rapidly and reliably measuring the blood concentration level of an intravenously administered analgesic/anesthetic medication is proposed, providing a key feedback element for closed loop target controlled infusion analgesia/anesthesia (TCIA) systems. The addition of direct measurement… more
Abstract:Peripheral neuropathy (PN) is condition in which a single nerve, nerve groups, or nerves become damaged. Neuropathic pain can be difficult to manage. Mild pain can be treated with over the counter analgesics. In cases when the pain is persistent and more severe, injections of, or topical patches… more
Abstract:Conventional Li ion batteries have a number of limitations that prevents them from becoming the energy storage media for electric (EV) and hybrid electric vehicles (HEV). Many of these limitations could be ultimately traced to properties and limitations of the liquid organic electrolytes used in the… more
Abstract:Weigh-In-Motion (WIM) has been employed as a major technology to collect heavy vehicles’ data on the freeways. Because WIM is one of the most costly and sophisticated data collection system, how to effectively utilize the valuable WIM data, monitor WIM stations' performance, and identify out of… more
Abstract:With continuing emphasis on transportation sustainability and fiscal stewardship, utilizing existing loop detector infrastructure to obtain more accurate, reliable and comprehensive traffic system performance measures is desired by many transportation agencies.

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
