In this paper, we will study optimality conditions of semi-infinite programs and generalized semi-infinite programs, for which the gradient objective function when evaluated at any feasible direction for the linearized constraint set is non-negative. We consider three types of penalty functions for semi-infinite program and investigate the relationship among the exactness of these penalty funct...

In this paper, we address the problem of exponential stability for a class linear hyperbolic systems with distributed sampled-data control. First, recast original system into hybrid model via an augmented approach. Using model, link between sampling interval, state and its sampled vector is characterized by Integral Quadratic Constraint (IQC). The obtained IQC used deriving numerically tractabl...

The effective string action of the color-electric flux tube in the U(1)×U(1) dual Ginzburg-Landau (DGL) theory is studied by performing a path-integral analysis by taking into account the finite thickness of the flux tube. The DGL theory, corresponding to the low-energy effective theory of Abelian-projected SU(3) gluodynamics, can be expressed as a [U(1)]3 dual Abelian Higgs (DAH) model with a ...

This work investigates Automatic Generation Control and optimal gain setting of conventional controller for multi area interconnected reheat thermal power systems. Conventional Proportional – integral – Derivative (PID) controller is used for this investigation. Optimization of controller gain values are tuned by Integral Time Absolute Error (ITAE) traditional approach. The proposed work presen...

Hartle’s generalized quantum mechanics in the sum-over-histories formalism is used to describe a nonabelian gauge theory. Predictions are made for certain alternatives, with particular attention given to coarse-grainings involving the constraint. In this way, the theory is compared to other quantum-mechanical descriptions of gauge theories in which the constraints are imposed by hand. The vanis...

the changing of round and back vowel /u/ to unround and front vowel [i] occurs in lori dialects as well as some other persian dialects. this vowel change includes both unrounding and fronting. this paper aimed at coming up with an inclusive ranking of constraints to explain occurrence and nonoccurrence of this vowel change in various phonological environments in silahkori dialect within optimal...

Ductile-brittle fracture transition was investigated using compact tension (CT) specimens from -70 o C to 40 o C for a carbon steel. Large deformation finite element analysis has been carried out to simulate the stable crack growth in the compact tension (CT, a/W=0.6), three point-point bend (SE(B), a/W=0.1) and centre-cracked tension (M(T), a/W=0.5) specimens. Experimental crack tip opening di...
