A new system is presented for general symbol segmentation, which is applicable for segmentation of any connected string of symbols, including characters and line diagrams. Using a powerful graph representation and an evolutionary algorithm framework, segmentation hypotheses are initialized and evolved towards a fully segmented and recognized string. The evolutionary segmentation was tested in m...

In this research, dynamic analysis of the rotational slender axially moving string is investigated. String assumed as Euler Bernoulli beam. The axial motion of the string, gyroscopic force and mass eccentricity were considered in the study. Equations of motion are derived using Hamilton’s principle, resulting in two partial differential equations for the transverse motions. The equations are ch...

We detail the construction of electric string solutions in $SU(2)$ Yang-Mills-Higgs theory with a scalar fundamental representation and discuss properties solution. show that Schwinger gluon pair production background is absent. A similar other models, such as an adjoint field electroweak model, does not yield solutions.

This paper describes a color-based image retrieval technique that uses a new representation for the color content of an image. The new representation, called Spiral Bit-string Representation, is an extension of the traditional bitmap signature representation, where the image description is performed in a spiral manner, starting from the centre of the image and moving clockwise towards the borde...

Verifying string manipulating programs is a crucial problem in computer security. String operations are used extensively within web applications to manipulate user input, and their erroneous use is the most common cause of security vulnerabilities in web applications. Unfortunately, verifying string manipulating programs is an undecidable problem in general and any approximate string analysis t...

Here quantum theory representations of real (R) and complex (C) numbers are described as equivalence classes of Cauchy sequences of states of single, finite strings of qukits where the qukit string states represent rational numbers. This work extends earlier work with qubit string states to qukit string states for any base k ≥ 2. Quantum theory representations differ from the usual classical re...

A bstract We formulate the stringy nonrelativistic limits of flat space and AdS 5 × S string as coset models, based on Bargmann extended Newton-Hooke algebras respectively. Our construction mimics typical relativistic one, but differs in several interesting ways. Using our formulation we give a Lax representation equations motion both models.

A perturbation theory with respect to the tension parameter γ/α ′ for the non–linear equations of string, moving in curved space–time, is considered. Obtained are linearized motion equations for the functions of the n−th degree of approximation (n = 0, 1, 2). The study of string dynamics in curved space–time has evoked considerable interest [1–3]. The investigation of this problem is hampered b...

An intrinsic part of information extraction is the creation and manipulation of relations extracted from text. In this article, we develop a foundational framework where the central construct is what we call a document spanner (or just spanner for short). A spanner maps an input string into a relation over the spans (intervals specified by bounding indices) of the string. The focus of this arti...

in this paper, the dynamical behavior of an axially moving string modeled by fractional derivative is investigated. the governing equation represented motion is solved by the method of multiple scales. considering principal parametric resonance, the stability boundaries for string with simple supports are obtained. numerical results indicate the effects of fractional damping on stability.
