Given the importance of students’ judgement of the future rewarding character of studying for their willingness to deliver effort at school, we propose the concept of sense of academic futility to understand track differences in achievement. As research is inconclusive in this matter, this study examines whether negative attitudes such as sense of ...

We investigate oscillating shock waves in a tube using a higher order weakly nonlinear acoustic model. The model includes thermoviscous effects and is non isentropic. The oscillating shock waves are generated at one end of the tube by a sinusoidal driver. Numerical simulations show that at resonance a stationary state arise consisting of multiple o...

We consider a class of functions, defined on a locally compact abelian group by letting a class of modulation operators act on a countable collection of functions. We derive sufficient conditions for such a class of functions to form a Bessel sequence or a frame and for two such systems to be dual frames. Explicit constructions are obtained via var...
