This paper is concerned with the analysis of a singularity that can occur in threedimensional discontinuous feedback control systems. The singularity is the two-fold – a tangency of orbits to both sides of a switching manifold. Particular attention is placed on the Teixeira singularity, which previous literature suggests as a mechanism for dynamical transitions in this class of systems. We show...

Understanding how small- and medium-sized enterprises develop foster resilience in their employees is critical to better adapt recover from challenges. Yet, such a process conducted not well-understood literature. Integrating the literature social exchange theory disaster framework, this research examines effects of servant leadership (SL) transparent communication (TC) on employees’ capacity f...

The unavoidable irreversible loss of power in a heat engine is found to be of quantum origin. Following thermodynamic tradition a model quantum heat engine operating in an Otto cycle is analyzed, where the working medium is composed of an ensemble of harmonic oscillators and changes in volume correspond to changes in the curvature of the potential well. Equations of motion for quantum observabl...

In the last decades, several factors have contributed to raising public concern over higher education institutions’ quality, leading to the emergence of quality measurement and improvement devices such as performance indicators, accreditation, programme and institutional assessment and quality audits, and there have been attempts to import models from the private sector into higher education sy...
