for many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. however, an issue that has rarely been studied is the speed of these methods. considering the computer hardware limitations, it is necessary for these methods to run in high speed. one of the methods to increase the processing speed is to use the computer pa...

different methods arising from scientific investigation for removing noise from chaotic signals have been introduced and one of their best is local projection approach. the local projection approach projects the chaotic data in the neighborhood onto the hyper-plane. selection of neighborhood radius has a direct impact on its performance. a noticeable feature associated with chaotic trajectories...

For a convex body K ⊂ Rn, the kth projection function of K assigns to any k-dimensional linear subspace of Rn the k-volume of the orthogonal projection of K to that subspace. Let K and K0 be convex bodies in Rn, let K0 be centrally symmetric and satisfy a weak regularity assumption. Let i, j ∈ N be such that 1 ≤ i < j ≤ n − 2 with (i, j) 6= (1, n−2). Assume that K and K0 have proportional ith p...

Abstract This paper establishes a mathematical model of basketball sports based on an ADDIE model. takes players’ pitching as the research object. Then use method to analyze best angle goal improve accuracy throwing. Firstly, this dynamic movement and then shows equation trajectory. uses optimize solve basketball. At same time, proposes motion control rotation using adaptive trajectory correcti...

CONTEXT Lymphoepithelial cysts of the pancreas show various presentations on imaging studies often making a differential diagnosis difficult. CASE REPORT A 58-year-old man was admitted to our hospital with epigastric discomfort and abdominal bloating. Abdominal US was carried out and demonstrated a cystic lesion 5 cm in diameter which included an intracystic projection into the pancreatic bod...

For a convex body K ⊂ Rn, the kth projection function of K assigns to any k-dimensional linear subspace of Rn the k-volume of the orthogonal projection of K to that subspace. Let K and K0 be convex bodies in Rn, and let K0 be centrally symmetric and satisfy a weak regularity and curvature condition (which includes all K0 with ∂K0 of class C2 with positive radii of curvature). Assume that K and ...

This article explores the use of unauthorised projection-based artworks and messages as a form activism, contextual street art. The issues authority permission that are central to political nature art unique in case projection ephemeral temporary light-based installations skirt some fundamental objections most graffiti such damage physical surfaces. Through changes imposed on urban forms by lig...

In Electrical Impedance Tomography (EIT) measurement sinusoidal currents are applied on a surface of the human body and voltage response is measured in order to reconstruct conductivity distribution in a body cross-section. We have constructed an experimental system for EIT measurement based on voltage response to short current pulses. In this case resistive components of body impedance are mea...

We introduce the concept of generalized projection operators, i.e., projection integrals over a body in R that generalize the usual result of projected area in a given direction by taking into account shadowing and scattering effects as well as additional convolution functions in the integral. Such operators arise naturally in connection with various observation instruments and data types. We r...
