An AlGaN tunnel junction light emitting diode operating at 255 nm
(2020-12-14)
We report on the demonstration of high-performance tunnel junction deep ultraviolet (UV) light-emitting diodes (LEDs) by using plasma- assisted molecular beam epitaxy. The device heterostructure was grown under slightly ...
Large-Scale Invariant Sets for Safe Coordination of Thermostatic Loads
(IEEE, 2021-03-22)
Systems often face constraints at multiple levels. For example, in coordinating a collection of thermostatically controlled loads to provide grid services, the controller must ensure temperature constraints for each load ...
Compositional Safety Rules for Inter-Triggering Hybrid Automata
(ACM, 2021-03-15)
In this paper, we present a compositional condition for ensuring safety of a collection of interacting systems modeled by inter-triggering hybrid automata (ITHA). ITHA is a modeling formalism for representing multi-agent ...
Bridging Walking and Slithering – Stokesian Locomotion
(2021-05-20)
Both legged locomotion and slithering motions typically utilize periodic gaits – repeating cycles of body shape
change that produce a net motion through the world. Legged locomotion can be viewed from the perspective of ...
Some Insights about Multi-legged Steering
(2020)
Thanks to their sprawled posture and multi-legged support, stability is not as hard to achieve for hexapedal robots as
it is for bipeds and quadrupeds. A key engineering challenge with hexapods has been to produce insect-like ...
Constant speed gaits should work across all speeds
(2021-07-15)
The Stokesian form of the reconstruction equation of Geometric Mechanics arises when the contact forces are so large compared to body inertia that the group momentum decays almost instantaneously. As special case of this ...
Fully Autonomous Mixed Signal SoC Design & Layout Generation Platform
(IEEE, 2020-08-16)
We present FASoC, the world’s first autonomous mixed-signal SoC framework driven entirely by user constraints, along with a suite of automated generators for analog blocks. The process agnostic framework takes high-level ...
