Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...

Two versions of the threshold contact process ordinary and conservative - are studied on a square lattice. In the first, particles are created on active sites, those having at least two nearest neighbor sites occupied, and ...

Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...

The purpose of this study was to evaluate the effect of occlusal contact area for loading on the cuspal defection and stress distribution in a first premolar restored with a high elastic modulus restorative material. The ...

We present a unique case of fingertip allergic contact dermatitis from sprinkling fish food containing the inciting allergen, propyl gallate. A 58-year-old woman presented with a 1-year history of dermatitis localized to ...

Mental health benefits have been linked to human interaction with nature. However, most studies have been carried out in developed countries, limiting the generalizability of empirical findings to other parts of the world. ...

In this work, we study how a contact/impact nonlinearity interacts with a geometric cubic nonlinearity in an oscillator system. Specific focus is shown to the effects on bifurcation behavior and secondary resonances (i.e., ...

This doctoral thesis presents results on the use of port Hamiltonian systems (PHS) and controlled contact systems for modelling and control of irreversible thermodynamic processes. Firstly, Irreversible PHS (IPHS) has ...
