G. Murugusundaramoorthy, S. Sivasubramanian, R. K. Raina Abstract. The authors introduce a new subclass UH(α, β, γ, δ, λ, k) of functions which are analytic in the open disc ∆ = {z ∈ C : |z| < 1}. Various results studied include the coefficient estimates and distortion bounds, radii of close-to-convexity, starlikeness and convexity and integral means inequalities for functions belonging to the ...

The exponential Teichmüller spaces $$E_p$$ , $$0\le p \le \infty$$ interpolate between the classical space ( $$p=\infty$$ ) and of harmonic diffeomorphisms $$(p=0)$$ . In this article, we prove existence non-variational critical points for associated functional: mappings f disk whose distortion is p-exponentially integrable, $$0<p<\infty$$ yet any diffeomorphism g(z) $${\mathbb {D}}$$ with $$g|...

A parabolic starlike function f of order ρ in the unit disk is characterized by the fact that the quantity z f ′(z)/ f (z) lies in a given parabolic region in the right half-plane. Denote the class of such functions by PS∗(ρ). This class is contained in the larger class of starlike functions of order ρ. Subordination results for PS∗(ρ) are established, which yield sharp growth, covering, and di...

We derive lens distortion and magnification profiles of four well known clusters observed with Subaru. Each cluster is very well fitted by the general form predicted for Cold Dark Matter (CDM) dominated halos, with good consistency found between the independent distortion and magnification measurements. The inferred level of mass concentration is surprisingly high, 8 < cvir < 15 (〈cvir〉 = 10.39...

the purpose of this ex-post facto research is study about relationship between executive function and cognitive distortion on delinquent juveniles and non-delinquent juveniles in tehran. statistical sample are 62 delinquent juveniles selected by purposeful selection from “the center of modification and training” and 82 people of non-delinquent juveniles selected by method of random sampling fro...

  Introduction: Geometric distortion is a major shortcoming of magnetic resonance imaging (MRI), which has an important influence on the accuracy of volumetric measurements, an important parameter in neurology and oncology. Our goal is to design and construct a new three- dimensional phantom using a 3D printer in order to measure geometric distortion and its reproducibility in...

Introduction Gradient-echo EPI as an ultrafast and T2*-sensitive MRI technique, is most commonly used in functional MRI. However, Gradient-echo EPI is vulnerable to susceptibility-induced local field inhomogeneities, which induces signal loss and distortion mostly in the phase encoding direction. Due to susceptibility artifacts, the brain regions near air-tissue and bone-tissue interface are di...

In this paper Embedded based Z-source multilevel inverter (ZSMLI) is proposed. This work implements a five level cascaded H-bridge Z-source inverter by using embedded control. Switching devices are triggered using embedded controller. In this controller coding is described by using switching table. The presence of Z-source network couples inverter main circuit to the power source that providing...

Background: The magnetic resonance imaging (MRI)-based radiotherapy planning method have been considered in recent years because of the advantages of MRI and the problems of planning with two images modality. The first step in MRI-based radiotherapy is to evaluate magnetic resonance (MR) images geometric distortion. Therefore, the present study aimed to evaluate system related geometric distort...
