The shell-model Monte Carlo (SMMC) technique transforms the traditional nuclear shell-model problem into a path-integral over auxiliary fields. We describe below the method and its applications to four physics issues: calculations of sd-pf shell nuclei, a discussion of electron-capture rates in pf -shell nuclei, exploration of pairing correlations in unstable nuclei, and level densities in rare...

In this paper the nano conical shell model is developed based on modified strain gradient theory. The governing equations of the nano truncated conical shell are derived using the FSDT, and the size parameters through modified strain gradient theory have been taken into account. Hamilton’s principle is used to obtain the governing equations, and the shell’s equations of motion are derived with ...

A method for the removal of ionospheric effects from single-frequency non-GPS radio navigation data through the use of data collected from a single collocated dualfrequency GPS receiver is presented. The method uses a local ionosphere model to estimate the total electron content (TEC) along any line of sight that differs from the GPS satellite lines of sight. Two novel models are investigated, ...
