The focus of this presentation is the spectral (in-)stability of periodic waves for the electronic Euler-Poisson system, a hydrodynamical model for understanding electron dynamics in plasmas. It is fo...
An implicit asymptotic-preserving and energy-charge conserving (APECC) Particle-In-Cell method is proposed to solve the Vlasov-Maxwell (VM) equations in the quasi-neutral limit. Charge conservation is...
Computer chips are packed with billions of microscopic transistors that enable powerful computation, but also generate a great deal of heat. A buildup of heat can slow a computer processor and make it...
With the addition of computers, laser cutters have rapidly become a relatively simple and powerful tool, with software controlling shiny machinery that can chop metals, woods, papers, and plastics. Wh...
A new algorithm helps drones find the fastest route around obstacles without crashing. The system could enable fast, nimble drones for time-critical operations such as search and rescue.
After two nerve-wracking months dedicated to the installation of the ALICE detector’s new Inner Tracking System (ITS), Corrado Gargiulo’s mechanical engineering team, in charge of the installation, ca...
Physicists at the Massachusetts Institute of Technology have designed a quantum "light squeezer" that reduces quantum noise in an incoming laser beam by 15%. It is the first system of its ki...
Hyperspectral and three-dimensional measurement can obtain the intrinsic physicochemical properties and external geometrical characteristics of objects, respectively. Currently, a variety of sensors a...
The topics of tolerancing, alignment, and verification are crucial in the development of successful optical systems. The effective assembly of optical systems requires alignment of different system co...
Scientists have long known the ins and outs of equilibrium thermodynamics. Systems in equilibrium — a stable state of unchanging balance — are governed by a neat set of rules, making them predictable ...

This article describes a new photogrammetric 3-D measurement system for flat objects like plywood boards. 3-D measurement is needed to get true dimensions of the object along its possibly curved sur...
The Ritchey-Chrétien (RC) optical design of Thirty Meter Telescope (TMT) calls for a 3.1m diameter secondary mirror (M2M) and an elliptical tertiary mirror (M3M) of 3.5m along its major axis and 2.5...
This paper presents refinements to the design of the TMT primary mirror segment passive-support system that are effective in reducing gravity print-through and thermal distortion effects. First, a no...
