The peridynamic correspondence model provides a general formulation to incorporate the classical local model and,therefore,helps to solve mechanical problems with discontinuities *** it suffers from zero-energy mode instability in numerical implementation due to the approximation of deformation gradient *** suppress zero-energy modes,previous stabilized methods were generally more based on adding a supplemental force state derived from bond-based peridynamic theory,which requires a bond-based peridynamic *** this work,we present an improved stabilized method where the stabilization force state is derived directly from the peridynamic correspondence ***,the bond-based peridynamic micro-modulus is *** improved method needs no extra constant to control the magnitude of stabilization force state and it is suitable for either isotropic or anisotropic *** examples are presented to demonstrate its performance in simulating crack propagation,and numerical results show its efficiency and effectiveness.

Infinite Freedom of Space-Time for zero-energy-Entity in Quantum Mechanics

引用

Journal of Modern Physics 2018年第4期9卷 525-531页

作者： Chun T. Rim GIST (Gwangju Institute of Science and Technology) Gwangju Korea

zero-energy state is investigated by taking infinitesimal energy and observing its uncertainty in space-time, adopting quantum mechanics. In this paper, the uncertainty in conventional quantum mechanics is found to be interpreted as freedom in space-time, which results in possibility of time travel and space transition of the zero-energy state, which could be information or mind. The wave function of a physical system composed of multiple particles or wave-packets is examined and found that it can be arbitrarily changed by grouping by observers. It leads to an idea that even infinitesimal energy or wave-packets in a heavy physical system may separately exist and it has the infinite freedom of space-time.

The Light-Dark Dual Universe for the Big Bang and Dark energy

引用

Journal of Modern Physics 2013年第7期4卷 77-84页

In the proposed light-dark dual universe, the light universe is the observable universe with light and kinetic energy that fueled the Big Bang, and the dark universe without light and kinetic energy has been observed as dark energy since about 9 billion years after the Big Bang. The light-dark dual universe started from the zero-energy universe through the four-stage cyclic transformation. Emerging from the zero-energy universe, the four-stage transformation consists of the 11D (dimensional) positive-negative energy dual membrane universe, the 10D positive-negative energy dual string universe, the 10D positive-negative energy dual particle universe, and the 4D (light)-variable D (dark) positive-negative energy dual particle asymmetrical universe. The transformation can then be reversed back to the zero-energy universe through the reverse four-stage transformation. The light universe is an observable four-dimensional universe started with the inflation and the Big Bang, and the dark universe is a variable dimensional universe from 10D to 4D. The dark universe could be observed as dark energy only when the dark universe turned into a four-dimensional universe. The four-stage transformation explains the four force fields in our universe. The theoretical calculated percentages of dark energy, dark matter, and baryonic matter are 72.8. 22.7, and 4.53, respectively, in nearly complete agreement with observed 72.8, 22.7, and 4.56, respectively. According to the calculation, dark energy started in 4.47 billion years ago in agreement with the observed 4.71 ± 0.98 billion years ago. The zero-energy cyclic universe is based on the space-object structures.

The Benefits of Integrated Methods in PV Making to Promote Their Efficiency and Achieve Low-Cost Modules

引用

Smart Grid and Renewable energy 2012年第1期3卷 27-33页

Active systems, such as solar thermal and photovoltaic offer a great potential in reducing of fuel energy consumption. To improve the sustainability of buildings, one of the challenges is to address the role of renewable energies. Today, the photovoltaic installations play an important role in creating solar renewable energy. They create 2000 MW electrical energy per year and its annual global sales grown to approximately 5.6 GWp. This paper presents a general overview on a serious effort to produce PV panels that could provide cheaper solar power. It also focuses on short background of PV. Furthermore, thin film technology benefits, the method of the most absorbing of solar spectrum and the method of solar concentration and the advantages of these systems are presented. Ultimately, a new high concentration PV power system will be assessed.
