Solving for Blameless and Optimal Control Under Prioritized Safety Constraints

Optimal Control Applications and Methods, EarlyView.
Summary of the proposed method for solving for blameless and optimal control sequences. ABSTRACT In many safety‐critical optimal control problems, users may request multiple safety constraints that are jointly infeasible due to external factors such as subsystem failures, unexpected disturbances, or fuel limitations.

Spectra of quadratic vector fields on $\mathbb{C}^2$: The missing relation

, 2018
Consider a quadratic vector field on $\mathbb{C}^2$ having an invariant line at infinity and isolated singularities only. We define the extended spectra of singularities to be the collection of the spectra of the linearization matrices of each of the ...

Optimal Gain Selection for the Arbitrary‐Order Homogeneous Differentiator

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Differentiation of noisy signals is a relevant and challenging task. Widespread approaches are the linear high‐gain observer acting as a differentiator and Levant's robust exact differentiator with a discontinuous right‐hand side. We consider the family of arbitrary‐order homogeneous differentiators, which includes these special cases.

The role of identification in data‐driven policy iteration: A system theoretic study

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

The topological classification of a family of quadratic differential systems in terms of affine invariant polynomials

, 2019
Summary: In this paper we provide affine invariant necessary and sufficient conditions for a non-degenerate quadratic differential system to have an invariant conic \(f(x,y) = 0\) and a Darboux invariant of the form \(f(x,y)^\lambda e^{st}\) with \(\lambda, s \in \mathbb R\) and \(s \neq 0\).

Do Single‐Sex STEM Programs Have Merit? If So, for Whom, on What Measures?

Science Education, EarlyView.
ABSTRACT Single‐sex STEM programs—defined here as voluntary, gender‐segregated extracurricular or supplemental activities (e.g., summer camps, workshops, robotics clubs, internships, or citizen science initiatives)—have experienced heightened popularity and scrutiny amid efforts to increase diversity in STEM fields.

Liquid Biopsy Differentiation of Pancreatic Cancer From Non‐Cancerous Pancreatic Disease Using Dielectrophoresis‐Recovered Nanoparticles Carrying Cell‐Free DNA and Protein Biomarkers

Small, EarlyView.
A new nanoparticle‐based biomarker panel is described that can differentiate pancreatic cancer from benign pancreatic disease with a high level of performance. This was enabled by microelectrode array recovery technology that used dielectrophoresis (DEP) to quickly and efficiently recover the nanoparticles from patient plasma samples, followed by on ...

A Dynamic Correlation‐Information‐Fusion‐Based Spatiotemporal Network for Traffic Flow Forecasting

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Traffic Flow Forecasting (TFF) is a foundational task in the development of Intelligent Transport Systems (ITSs). The primary challenge is to undertake a comprehensive exploration of the intrinsic dynamic spatiotemporal correlations of the road network, unveiling the long‐term evolutionary traffic trends.
