The purpose of this study is to investigate and identify the periods of formation and bursting of speculative bubbles in Iran's capital market by creating a state space model and two-mode switching regime (mode 1 is bubble growth and burst stage and mode 2 is the time of bubble loss) during the period from April 2011 to March 2018. The Oxmetrics 7 software is used to investigate the existence o...

Measures corresponding to quadratic exponential families can be characterized in a number of ways. For example, the generating function for their orthogonal polynomials has a special form, their Laplace transforms satisfy differential equations, etc. To this list we add a representation on a modified symmetric Fock space. For most of the talk, we will concentrate on the non-commutative version ...

The paper examines the stabilization and the H∞ norm performance analysis and control of state-delayed systems with a symmetric state-space realization. Such symmetric realizations appear in many engineering applications. By exploiting the state-space symmetry, we obtain an explicit solution for a bound on the H∞ norm of such symmetric time-delayed systems. Also, we derive an explicit parametri...

Photovoltaic systems integrated to the grid have received considerable attention around the world. They can be connected to the electrical grid via galvanic isolation (transformer) or without it (transformerless). Despite making galvanic isolation, low frequency transformer increases size, cost and losses. On the other hand, transformerless PV systems increase the leakage current (common-mode c...
