Risk‐aware safe reinforcement learning for control of stochastic linear systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

A Class of Potentials in Weighted Hardy-Type Inequalities with a Finite Number of Poles

Mathematics
In this paper, we discuss potentials for which we obtain multipolar weighted Hardy-type inequalities for a class of weights that are wide enough. Examples of such potentials are shown. The weighted estimates are more general than those stated in previous

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

Asian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Physical Fitness Profiles Among Children and Adolescents With ADHD and ASD: A Comparison With Typically Developing Peers

Autism Research, EarlyView.
ABSTRACT Children and adolescents with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) often present physical and motor challenges that may compromise health, yet direct comparisons between these neurodevelopmental conditions and typically developing (TD) peers remain limited.

Exponential inequalities for a class of operators

International Journal of Mathematics and Mathematical Sciences, 2002
Characterizations of weight pairs are proved for which weighted exponential-logarithmic integral inequalities are satisfied. The results given contain characterizations of weights for which inequalities involving the Riemann-Liouville and Laplace type ...

Improved Poincaré inequalities with weights

Journal of Mathematical Analysis and Applications, 2008
In this paper we prove that if $ \in\mathbb{R}^n$ is a bounded John domain, the following weighted Poincare-type inequality holds: $$ \inf_{a\in \mathbb{R}}\| (f(x)-a) w_1(x) \|_{L^q( )} \le C \|\nabla f(x) d(x)^ w_2(x) \|_{L^p( )} $$ where $f$ is a locally Lipschitz function on $ $, $d(x)$ denotes the distance of $x$ to the boundary of $ $, the ...

Understanding the paradox of primary teacher shortage in low‐income countries: Insights from Malawi

British Educational Research Journal, EarlyView.
Abstract Malawi faces a persistent and chronic teacher shortage, particularly at the primary school level, with much of the challenge attributed to teacher supply constraints. While the causes of teacher shortages are known to be complex and context‐dependent, there remains a lack of in‐depth, country‐specific research to guide effective policies ...
