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 ...
Classification of driving behaviors using STL formulas: A Comparative Study
(2022-07-15)
In this paper, we conduct a preliminary comparative study of the classification of longitudinal driving behavior using Signal Temporal Logic (STL) formulas. The goal of the classification problem is to distinguish between ...
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 ...
Convergence of a Grassmannian Gradient Descent Algorithm for Subspace Estimation From Undersampled Data
(2022-02-20)
Subspace learning and matrix factorization problems have great many applications in science and engineering, and efficient algorithms are critical as dataset sizes continue to grow. Many relevant problem formulations are ...
Clustering-based Mode Reduction for Markov Jump Systems
(2022-04-05)
While Markov jump systems (MJSs) are more appropriate than LTI systems in terms of modeling abruptly changing dynamics, MJSs (and other switched systems) may suffer from the model complexity brought by the potentially sheer ...
