I explain the geometric basis for the recently-discovered nonholonomic mapping principle which enables me to derive laws of nature in spacetimes with curvature and torsion from those in at spacetime, thus replacing and extending Einstein's equivalence principle. An important consequence is a new action principle for determining the equation of motion of a free spinless point particle in such sp...

The lecture explains the geometric basis for the recently-discovered nonholonomic mapping principle which specifies certain laws of nature in spacetimes with curvature and torsion from those in flat spacetime, thus replacing and extending Einstein's equivalence principle. An important consequence is a new action principle for determining the equation of motion of a free spinless point particle ...

This paper aims at investigating the nonlinear behavior of a system which is consisting of two free-free beams which are connected by a nonlinear joint. The nonlinear system is modelled as an in-extensional beam with Timoshenko beam theory. In addition, large amplitude vibration assumption is taken into account in order to obtain exact results. The nonlinear assumption in the system necessities...

In this paper, we introduce a new parameter, called inertia weight, into the original particle swarm optimizer. Simulations have been done to illustrate the signilicant and effective impact of this new parameter on the particle swarm optimizer.

We present an approach to understanding the origin of inertia involving the electromagnetic component of the quantum vacuum and propose this as a step toward an alternative to Mach's principle. Preliminary analysis of the momentum flux of the classical electromagnetic zero-point radiation impinging on accelerated objects as viewed by an inertial observer suggests that the resistance to accelera...

Two series of experiments are performed to investigate the dynamic response of various essential components of a class of sandwich structures, under high-rate inertial loads. One consists of dynamic inertia tests and the other involves dynamic impact tests. A split Hopkinson bar apparatus is modified and used for these experiments. First, the energy-absorbing characteristics of the plate materi...

The brushless doubly-fed wind power system based on conventional control strategies lacks ‘inertia’ and the ability to support grid, which leads decline of grid stability. Therefore, a strategy reluctance generator (BDFRG) virtual synchronous (VSG) is proposed solve problem in this paper. output characteristics BDFRG VSG are similar (SG), can frequency increase ‘inertia’. According mathematical...

Renewable energy sources (RESs) are generally connected to the grid through power electronic interfaces, which generate electrical instantaneously with little inertia. With increasing penetration of RESs, will gradually develop into a low inertia and underdamped system, results in serious frequency stabilization problems. The virtual synchronous generator (VSG) is an emerging technology that mi...

In this paper, we study the impact of institutional inertia on the implementation of market-oriented reform programs. We examine the problem of a government who can introduce efficiency-enhancing reforms to increase the rate of economic growth by inducing, via monetary compensations, low productivity workers to exit the sector. In our baseline scenario without institutional inertia, efficiency ...
