Hyperspectral images have significant applications in various domains, since they register numerous semantic and spatial information the spectral band with variability of signatures. Two critical challenges identifying pixels hyperspectral image are respectively representing correlated among local global, as well abundant parameters model. To tackle this challenge, we propose a Multi-Scale U-sh...
We consider the nonlinear eigenvalue problem −u′′(t) = f(λ, u(t)), u > 0, u(0) = u(1) = 0, where λ > 0 is a parameter. It is known that under some conditions on f(λ, u), the shape of the solutions associated with λ is almost ‘box’ when λ 1. The purpose of this paper is to study precisely the asymptotic shape of the solutions as λ → ∞ from a standpoint of L1-framework. To do this, we establish t...
The maximal representation of a shape is defined and algorithms for shape arithmetic are developed. Introduction A shape is any arrangement of spatial elements from among points, or lines, planes, volumes, or higher dimensional hyperplanes of limited but nonzero measure. According to Stiny (1991), a shape is in algebra U, or simply in U, whenever it is made up of elements from U. Thus, a shape ...
چکیده: مقدمه و هدف: آگاهی از آناتومی کانال خصوصاً در آناتومی های پیچیده مثل کانال های c-shape برای انجام یک درمان موفق ضروری می باشد. از آنجا که در کانال های c-shape نحوه ارتباط از کرونال تا آپیکال در نحوه درمان انجام شده مهم است تشخیص وضعیت آناتومیک این کانال ها می تواند اهمیت زیادی داشته باشد. در این مطالعه، مقایسه ای بین پنج روش مختلف برای تشخیص آناتومی c-shape انجام گرفته تا روشی دقیق برای...
Using the most accurate potential curves available for the a (u 1 and X (g 1 states of lithium molecules, we compute the positions of shape resonances. We also calculate the deexcitation probability from a bound level v8 with rotational number N8 to the continuum of the lower state, and conclude that a shape resonance should be measurable for the transition 2 )g ̃a (u 1 . Such a shape resonance ...
We report the first three-dimensional photonic metamaterial, an array of erected U-shape plasmonic gold meta-molecules, that exhibits a profound response to the magnetic field of light incident normal to the array. The metamaterial was fabricated using a double exposure e-beam lithographic process. It was investigated by optical measurements and finite-element simulations, and showed that the m...
