A three-dimensional harmonic oscillator is studied in the context of generalized coherent states. We construct its squeezed states as eigenstates of linear contribution of ladder operators which are associated to the generalized Heisenberg algebra. We study the probability density to show the compression effect on the squeezed states. Our analysis reveals that squeezed states give us some freedom on the precise knowledge of position of the particle while maintaining the Heisenberg uncertainty relation minimum, squeezed states remains squeezed states over time.

To investigate the dynamic behavior of beams with partially delaminated layers, a model is presented in this work. This model takes into account the lateral strains. The principal advantage of the element is that it allows the modeling of delamination anywhere in the structure. The region without delamination is modeled to carry constant peel and shear stresses. Numerical results of the present model are presented and its performance is evaluated.

This study aims to investigate the influence of various parameters on the properties and quality of a foamed paste for printing with reactive dyes. The results show that the paste foamed has a lower viscosity than the paste usually because of the small amount of surfactant implementation which provides a better dyeing efficiency and water savings Thus, the fastness of fabrics printed with the paste foamed are the same as regular paste.
