in this paper, a new topology for boost z-source inverterbased on switched-inductor cell is proposed. the operating modes of the proposed inverter are analyzed and also a suitable control method to generate the trigger signals of the inverter is presented. having a common earth between the input source and inverter and capability to generate a higher voltage gain by using lower amounts of the d...

In this paper, the problems of control and stabilization of switched nonlinear cascade systems is investigated. The so called simultaneous domination limitation (SDL) is introduced in previous works to assure the existence of a common quadratic Lyapunov function (CQLF) for switched nonlinear cascade systems. According to this idea, if all subsystems of a switched system satisfy the SDL, a CQLF ...

in the present paper, we develop a modified pseudospectral scheme for solving an optimal control problem which is governed by a switched dynamical system. many real-world processes such as chemical processes, automotive systems and manufacturing processes can be modeled as such systems. for this purpose, we replace the problem with an alternative optimal control problem in which the switching t...

Background: Patients with unclassified hypogammaglobulinemia (UCH) constitute a diagnostic and therapeutic dilemma, because information concerning the clinical and immunological characteristics of these patients is insufficient. Objective: To evaluate B-cell subsets in cases with UCH and common variable immunodeficiency (CVID) and their association with treatment requirement in UCH patients. Me...

introduction: trichophyton rubrum is one of the most common species of dermatophytes which affects superficial keratinous tissue. it is not especially virulent but it can be responsible for considerable morbidity. although there are different therapeutic modalities to treat fungal infections, clinicians are searching for alternative treatment because of the various side effects of the present t...

Background: Although cryotherapy has been reported as atechnique for depigmenting residual pigmented patches inpatients with universal vitiligo, Q-switched Nd-YAG lasershave not yet been used for this purpose. The aim of this studywas to compare the efficacy of cryotherapy with that of 532nmQ-switched Nd-YAG laser therapy for depigmentation in patientswith universal vitiligo.Method: Six adult p...

what does libertarian theory, murray rothbard’s theory in particular, tell us about the rights of children? the two foundational principles of rothbardian libertarianism are the sanctity of private property and the rule of non-aggression. persons, including children, are “self-owners”. yet children, at a young age, are not yet capable of functioning fully as “self-owners.” they must be cared fo...
