How to efficiently map virtual networks (VNs) onto a shared physical network is a challenging issue in the field of network virtualization in edge-of-things computing. Since an efficient VN mapping approach can reduce network resource consumption, lower latency, and enhance service reliability, it is important for both customers and network service providers. In this paper, we study the problem...

Image segmentation is an important process in computer vision. Recently fuzzy logic based edge detection heavily investigated as by changing the number of rules can be improved. However, due to large colour variations images false edges are detected and even using they cannot reduced significantly. These falsely controlled smoothen filter while controlling degree smoothness. This paper, present...

LiDAR-based semantic segmentation, particularly for unstructured environments, plays a crucial role in environment perception and driving decisions unmanned ground vehicles. Unfortunately, chaotic especially the high-proportion drivable areas large-area static obstacles therein, inevitably suffer from problem of blurred class edges. Existing published works are prone to inaccurate edge segmenta...

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...

introduction and objectives: nulliparous women with unplanned pregnancy experience high levels of anxiety, which may adversely affect maternal-fetal attachment. therefore, in this study, we aimed to determine the effect of guided imagery on maternal-fetal attachment in nulliparous women with unplanned pregnancy. materials and methods: in this clinical trial, 67 nulliparous women with unplanned ...

In this research paper, we present a novel frame work for handling $m$-polar information by combining the theory of $m-$polar fuzzy  sets with graphs. We introduce certain types of edge regular $m-$polar fuzzy graphs and edge irregular $m-$polar fuzzy graphs. We describe some useful properties of edge regular, strongly edge irregular and strongly edge totally irregular $m-$polar fuzzy graphs. W...

Introduction: Guided mode resonance is generated by coupling wave diffractions with the waveguided mode. The guided resonances provide narrow-linewidth and intensity for high quality factor (Q-factor) optical resonators. Methods: we demonstrate high-Q propagating on a low-loss, terahertz guided-mode magnetic system, which are periodic square lattices of U-shaped split ring resonators (SRRs) qua...

BACKGROUND Incomplete strut coverage has been documented an important histopathologic morphometric predictor for later thrombotic events. This study sought to investigate whether optical coherence tomography (OCT)-guided percutaneous coronary intervention with Nobori biolimus-eluting stent implantation in patients with non-ST-segment-elevation myocardial infarction would provide improved strut ...

Structural health monitoring based on guided wave plays an important role in the damage evaluation of practical application. However, the damage evaluation under time-varying environments which introduces undesired uncertainties to guided wave features is difficult to achieve reliably. In this paper, an approach of guided wave based Hidden Markov Model (HMM) method is proposed to improve the re...
