Cardiac arrhythmia refers to any abnormal electrical activity in the heart that causes irregular heartbeat. Under clinical settings, the arrhythmias can be monitored non-invasively using the electrocardiogram (ECG). Although reliable, the method is still prone to error due to its dependence on visual interpretation. Further, ECG data is enormous in dimension and increases as the data sampling r...

Absrract-This work IS a continuation of our earlier work on the Generalized Guard-zones Algorithm (GGA) for self-supervised parameter learning. An atlempt is made here for the automatic determination of the guard-zone parameter i' N (i.e. the threshold used for discarding doubtful or mislabeled samples) at every instant of learning, for the general m-elass N-featu re pattern recognition problem...

In this paper we study the hardness of the k-Center problem on inputs that model transportation networks. For the problem, an edge-weighted graph G = (V,E) and an integer k are given and a center set C ⊆ V needs to be chosen such that |C| ≤ k. The aim is to minimize the maximum distance of any vertex in the graph to the closest center. This problem arises in many applications of logistics, and ...

individuals act differently in learning, this being due to the difference in learning styles of persons. learning styles affect optimum learning and the efficiency in educational output. therefore an identification of the learning styles of learners as related to teaching and learning activities is most important. the purpose of this study was to investigate the learning styles of agricultural ...

Abstract We propose a random-subspace algorithmic framework for global optimization of Lipschitz-continuous objectives, and analyse its convergence using novel tools from conic integral geometry. X-REGO randomly projects, in sequential or simultaneous manner, the high-dimensional original problem into low-dimensional subproblems that can then be solved with any global, even local, solver. estim...

background: malocclusion, as a worldwide issue, can cause a lot of problems for patients. panoramic (pr) and lateral cephalometric (lcr) radiographs are both usually indicated for orthodontic treatments. the aim of this study was to analyze vertical and sagittal parameters of both jaws on prs and to compare them on lcrs. materials and methods: in this cross sectional study, 61 samples from all ...

let r be a right gf-closed ring with finite left and right gorenstein global dimension. we prove that if i is an ideal of r such that r/i is a semi-simple ring, then the gorensntein flat dimensnion of r/i as a right r-module and the gorensntein injective dimensnnion of r/i as a left r-module are identical. in particular, we show that for a simple module s over a commutative gorensntein ring r, ...

This paper presents a novel approach to design a parametric RF stop band pass filter based on Low Temperature Co-fired Ceramic (LTCC) Technology. The LTCC technology enables to miniaturize and development compact structures using not only the standard xy-planar circuit dimensions but also the zheight dimension. The proposed filters topologies are based on a stripline loaded with one or several ...

The problem of finding an approximation to a geometric line by a discrete line using pixels is ubiquitous in computer graphics applications. We show that this discrete line problem in R n+1, for grids of any shape, is equivalent to a geometry problem in Rn concerning the minimization of the distance that a certain type of closed polygonal path wanders from the origin. This geometry problem is s...
