Bridging Gaps in STEMM Education: The Role of Culturally Responsive Pedagogy and Mentorship in Preparing Future Teachers

Future in Educational Research, EarlyView.
ABSTRACT A Summer Research Program (SRP) at a large public university in the southern United States prepares undergraduate STEM majors to engage with high school students from underrepresented backgrounds. Grounded in culturally responsive pedagogy (CRP) and layered mentorship, SRP fosters inclusive teaching practices and professional growth among ...

A Deep Learning Framework for Forecasting Medium‐Term Covariance in Multiasset Portfolios

Journal of Forecasting, EarlyView.
ABSTRACT Forecasting the covariance matrix of asset returns is central to portfolio construction, risk management, and asset pricing. However, most existing models struggle at medium‐term horizons, several weeks to months, where shifting market regimes and slower dynamics prevail.

Managers' Decisions About Informal Accommodation Requests by Employees With and Without Disabilities

Human Resource Management, EarlyView.
ABSTRACT Although formal accommodations are required by law across many jurisdictions, many employees seek informal adjustments to their work conditions. These individualized work arrangements are not rooted in legal compliance but are instead provided at managers' discretion.

Robust disturbance rejection

Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002
The problem of robust asymptotic disturbance rejection for systems involving parametric uncertainties is studied. A design method is proposed that is based on polynomial techniques. Various uncertainty structures are considered including single and multiple parameters as well as affine, polynomic and even non-polynomic cases.

Fractional active disturbance rejection control

ISA Transactions, 2016
A fractional active disturbance rejection control (FADRC) scheme is proposed to improve the performance of commensurate linear fractional order systems (FOS) and the robust analysis shows that the controller is also applicable to incommensurate linear FOS control.

On perfect disturbance rejection

Proceedings of 32nd IEEE Conference on Decision and Control, 2002
A new observer-based approach to perfect disturbance rejection in linear continuous systems is introduced. A technique of continuous deadbeat observation is exploited to estimate the disturbance signal described by a known dynamic model. A realization condition in the form of linear algebraic equations is derived.

Adaptive disturbance rejection

[1991] Proceedings of the 30th IEEE Conference on Decision and Control, 2002
Using averaging analysis a novel direct adaptive algorithm applied to a linear plant is analyzed. The prior knowledge includes a nominal model and a stabilizing controller for the plant. It is shown that the stabilizing controller can be augmented with an adaptive controller solely aimed at disturbance rejection/trajectory following. The overall scheme

Steering Torque Disturbance Rejection

SAE International Journal of Vehicle Dynamics, Stability, and NVH, 2017
<div class="section abstract"><div class="htmlview paragraph">The layout of a vehicle steering system has to resolve a compromise. While it is important for lateral vehicle control to feel steering torque feedback of lateral tire to ground interaction, disturbing forces shall not be present in the feedback steering torque.

Decoupling and disturbance rejection

IEEE Transactions on Automatic Control, 1975
For the linear multivariable system \dot{x} = Ax + Bu + Er, z_{i} = D_{i}x(i \in k), x \in X , with disturbance \Gamma(\cdot) , it is shown that the decoupling problem and disturbance rejection problem are simultaneously solvable, so as to yield a stable closed-loop system, if and only if Im(E)\subset V_{g}^{*} and R_{i}^{*} + \ker D_{i} = X, i \in k .
