in this paper the meshless local petrov-galerkin (mlpg) method is implemented to study the buckling of isotropic cylindrical shells under axial load. displacement field equations, based on donnell and first order shear deformation theory, are taken into consideration. the set of governing equations of motion are numerically solved by the mlpg method in which according to a semi-inverse method, ...

The main goal of this study is the use of Lyapunov’s stability theory to a three-phase four-wire shunt active power filter (SAPF), since this method has been applied effectively to other areas of converter. The dynamic model of the SAPF is first established, after that, a combination of fuzzy tracking control and Lyapunov function is suggested in order to impose a desired transient waveform on ...

Abstract The current paper studies the formal properties of Global Reflection Principle, to wit assertion “All theorems $\mathrm {Th}$ are true,” where is a theory in language arithmetic and truth predicate satisfies usual Tarskian inductive conditions for formulae arithmetic. We fix gap Kotlarski’s proof from [15], showing that Principle Peano Arithmetic provable compositional with bounded ind...

Abstract It was supposed for fifty years that the conformal gauge in string theory exists globally on whole world sheet. In fact, almost all results were obtained under this assumption. However, statement proved only locally some neighbourhood of an arbitrary point worldsheet, and its extension is far from being obvious. present paper we prove does worldsheet represented by infinite strip with ...

this paper examines the relationship between environmental law and intellectual property law in light of international documents and procedures. the key question raised here is the role of intellectual property law in conservation of global environment. in this regard, we can express two general approaches: the neutral theory of intellectual property right and the systemic theory of intellectua...
