چکیده: 

In this paper, we introduce  a single integral transform that  defines all known Time scales generalized integral transforms in the family of Laplace transform as the new general integral transform on Time scales. As a result, a unified approach is developed for the use of integral transforms representing the family of Laplace transform for solving problems on continuous and discrete cases dynamics. The convergence  conditions and some principal properties accompanying the convolution theorem are given. It is shown that all generalized integral transforms on Time scales included in the family of the Laplace transform are special cases of a new general integral transform. The applicability of this transform is demonstrated by solving certain ordinary dynamic equations and integral equations.

چکیده: 

In this paper some new Hardy–type inequalities on Time scales are derived and proved using the concept of superquadratic functions. Also, we extend Hardy–type inequalities involving superquadratic functions with general kernels to the case with arbitrary Time scales. Several consequences of our results are given and their connection with recent results in the literature are pointed out and discussed.

چکیده: 

In this paper, we present a generalization of the Montgomery Identity to various Time scale versions, including the discrete case, continuous case, and the case of quantum calculus. By obtaining this generalization of Montgomery Identity  we establish results about the generalization of Ostrowski-Gr\"{u}ss like inequality to the several Time scales, namely discrete case, continuous case and the case of quantum calculus. Additionally, we recapture several published results from different authors in various papers, thus unifying the corresponding discrete and continuous versions. Furthermore, we demonstrate the applicability of our derived consequence to the case of quantum calculus.

چکیده: 

In this paper, we study the concept of generalized differentiability for fuzzy-valued functions on Time scales. Using the derivative of the product of two functions, we provide solutions to first order linear fuzzy dynamic equations. We present some examples to illustrate our results.

چکیده: 

THIS PAPER ATTENTION ON THE CONCEPT OF FLATNESS AND ITS PRACTICAL APPLICATION TO THE DESIGN OF AN OPTIMAL TRANSIENT CONTROLLER FOR A SYNCHRONOUS MACHINE. THE FEEDBACK LINEARIZATION SCHEME OF INTEREST REQUIRES THE GENERATION OF A FLAT OUTPUT FROM WHICH THE FEEDBACK CONTROL LAW CAN EASILY BE DESIGNED. THUS THE COMPUTATION OF THE FLAT OUTPUT FOR REDUCED ORDER MODEL OF THE SYNCHRONOUS MACHINE WITH SIMPLIFIED TURBINE DYNAMICS IS HEREBY PRESENTED. THE CORRESPONDING LINEARIZED COMPENSATOR IS DERIVED AS WELL AS THE NONLINEAR CONTROLLER FOR TRANSIENT STABILIZATION OF A SYNCHRONOUS MACHINE SUBJECTED TO LARGE DISTURBANCES. THE TRANSIENT BEHAVIOR OF A SINGLE MACHINE EQUIPPED WITH THE SO DESIGNED NONLINEAR CONTROLLERS FEEDING AN INFINITE BUS IS ILLUSTRATED VIA SIMULATION IN MATLAB ENVIRONMENT. THE RESULTS OBTAINED FOR TRANSIENT DISTURBANCES ON THE SINGLE MACHINE INFINITE BUS SYSTEM (SMIBS) ARE PRESENTED AND COMPARED WITH OTHER CONTROL ALGORITHMS TO DEMONSTRATE THE EFFECTIVENESS OF THE PROPOSED SCHEME.

چکیده: 

Conventional dynamic models in Economics are usually expressed in discrete or continuous Time. A new modelling technique-Time scale calculus-uni es both of these approaches into a general frame-work. In this paper, we present and construct a dynamic Optimization problem from economics in which the utility function is  h-concave, the value function and constraints are on di erent Time scales. The calculus of variations and optimal control are employed, with the aid of the newly in-troduced diamond- h dynamic calculus by the authors [12] on Time scales, to obtain a solution. The Hermite-Hadamard inequality with the diamond- h dynamic integral on Time scales, follows a proof of the new model. The new diamond- h Time scale model unify various related existing models involving general and more complex Time domains.
