In this paper, exact closed-form solutions for displacement and stress components of thick-walled functionally graded (FG) spherical pressure vessels are presented. To this aim, linear variation of properties, as an important case of the known power-law function model is used to describe the FG material distribution in thickness direction. Unlike the pervious studies, the vessels can have arbit...

Supervised statistical learning has become a critical means to design and learn visual concepts (e.g., faces, foliage, buildings, etc.) in content-based indexing systems. The drawback of this approach is the need of manual labeling of regions. While several automatic image annotationmethods proposed recently are very promising, they usually rely on the availability and analysis of associated te...

In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...

We introduce method of approaching local class field theory from the perspective of Lubin-Tate formal groups. Our primarily aim is to demonstrate how to construct abelian extensions using these groups.

we introduce and  study  fuzzy (co-)inner product and fuzzy(co-)norm of hyperspaces. in this regard by considering  the notionof hyperspaces, as a generalization of vector spaces, first we willintroduce the notion of fuzzy (co-)inner product in hyperspaces and will apply it to formulate the notions offuzzy (co-)norm and fuzzy (co-)orthogonality  in hyperspaces. inparticular, we will prove that ...

communication between subarachnoid and per lymphatic spaces can be due to a deficiency of lamina crib rosa (stapes gusher). recognition of the condition may alter the course of treatment that can avoid perilymph gushing. a five-year-old boy presented with a history of congenital hearing loss and recurrent meningitis. the computed tomography (ct) of the temporal bone showed severe bilateral dysp...
