The Yrast spectrum of( 178-184)Os nuclei up to high angular momentum states has been calculated using the PSM model (Projected Shell Model). For this purpose, plots of back-bending, energy, and reduced electromagnetic transition probabilities in high spins have been drawn. In the energy ...
3.2 FE model for the core tube The shear walls and coupling beams in the core tube are simulated by the multi-layer shell elements proposed by Miao et al. [21]. A schematic diagram of the element is shown in Fig. 4. This type of element is based on the principles of composite materi...
One of the strengths of the World Energy Model (WEM) that sits behind our scenarios is the ability to drill down into single countries, technologies in countries or sectors in countries. And I have done just that for the USA with the WEM to illustrate the pathways for our two new scenari...
We have developed a shell model force-field that reproduces the details of the phase diagram of the Pb(Zr1-xTix)O3 (PZT) solid solution compound, including the low and high temperature phases of PbZrO3 and PbTiO3. The developed force-field supports the temperature induced phase transitions ...
model of a closedcircular cylindrical shellwith internal fluid. The formulation is verified and its performance and efficiency in calculatingperiodic structuresand elastic phononic crystals are evaluated. In this sense, the band gaps generated by the Bragg scattering effect and the attenuation bands of ...
Diagramatic perturbation treatment of the effective interaction between two-photon states in closed shell nuclei: TheJπ= 0+states in208Pb In the collective model the 2p, 2h and 1p - 1h states are usually referred as the elementary excitations of the closed shell systems. The coupling ... RA...
The standard model (SM) of particle physics provides an elegant description for the masses and interactions of fundamental particles. These are fermions, which are the building blocks of ordinary matter, and gauge bosons, which are the carriers of the electroweak (EW) and strong forces. In addit...
It is shown that including form factors for the quark-pseudoscalar meson couplings of the Georgi-Manohar chiral quark model allows one to obtain the leading off-shell dependence of $\\pi^{o}- \\eta$ mixing (as predicted by chiral perturbation theory) from the effect of quark loops on the...
As regards the dynamic behaviour of conical tanks, we note that in 2002, Sweedan and El Damatty [56] investigated elevated conical steel vessels on the basis of both experimental model tests and numerical FEM modelling. They considered the case when the conical tanks were empty, to obtain natu...
The assessments were made by the MIT Joint Program using their climate model and also reported with the release of the Shell scenarios. You can also explore the scenario data here. The Energy Security Scenarios complement the IPCC Synthesis Report well in that Sky 2050 sets out a very clear ...
