Controllability and Observability Conditions for Impulsive DAEs on Time Scales
Asian Journal of Control, EarlyView.ABSTRACT This paper establishes criteria for controllability and observability in a class of linear time‐invariant impulsive differential‐algebraic equations (DAEs) defined on a time scale. Controllability is defined as the ability to transfer the system state from any initial condition to any desired state within a finite time interval using an ...

Case Study of a Fly's Eye Homogenizer for the Calibration Illumination of Integral Field Units
Astronomische Nachrichten, EarlyView.ABSTRACT Integral‐field unit spectrographs require a homogeneous calibration illumination of the field of view for proper flat and wavelength calibration (e.g., BlueMUSE which is currently under development for the VLT). This article presents the adaptation of a fly's eye homogenizer, frequently used in laser applications, to this task in astronomical ...

Batteries &Supercaps, Volume 8, Issue 3, March 2025.“A simple 1D transfer matrix model of a battery is introduced and parametrized using harvested individual cell components at 0 % and 100 % SoC. This model allows for the calculation of group velocity and attenuation. The results of the model show good agreement with measured values, highlighting increased attenuation and group velocity at the ...

Understanding out‐of‐field teacher self‐efficacy beliefs: A person‐centred approach
British Educational Research Journal, EarlyView.Abstract Teaching out‐of‐field (OOF) has been a widespread global phenomenon and a cause of concern for school leaders and policymakers due to the potential impact it has on teaching quality and student learning. However, research on how the nature of OOF teaching impacts various teachers' psychological attributes such as teacher self‐efficacy (TSE ...

Expansions in Appell polynomials of the convolutions of probability distributions
Nonlinear Analysis, 2013 We use the composition method to analyse the convolutions of probability distributions by emploing the Appell polynomials and Bergström identity. Our approximation is based on the probability distributions which have the inverse generalized measure of ...
