Isometric Shape Representation by Integrating Shape Function Maps and Deep Learning

open access: yesIEEE Access, 2019
With the wide application of isometric 3D models, the representation and recognition of them receive increasing attention. Most existing methods for shape representation and analysis either focus on using the constrained hand-craft models or purely ...

Atrial Fibrosis Hampers Non-invasive Localization of Atrial Ectopic Foci From Multi-Electrode Signals: A 3D Simulation Study

open access: yesFrontiers in Physiology, 2018
Introduction: Focal atrial tachycardia is commonly treated by radio frequency ablation with an acceptable long-term success. Although the location of ectopic foci tends to appear in specific hot-spots, they can be located virtually in any atrial region ...

A framework for evaluating epidemic forecasts

open access: yesBMC Infectious Diseases, 2017
Background Over the past few decades, numerous forecasting methods have been proposed in the field of epidemic forecasting. Such methods can be classified into different categories such as deterministic vs.

Computer simulation of channel processes [PDF]

open access: yesE3S Web of Conferences, 2019
The article discusses the results of numerical studies of flow movement with a sharp change in the channel parameters. The numerical study of the flow in the channels and rivers creates the possibility of a multivariate forecast of channel processes ...

Instability of Reissner–Nordström black hole in Einstein-Maxwell-scalar theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The scalarization of Reissner–Nordström black holes was recently proposed in the Einstein-Maxwell-scalar theory. Here, we show that the appearance of the scalarized Reissner–Nordström black hole is closely related to the Gregory-Laflamme instability of ...

Stability of scalarized charged black holes in the Einstein–Maxwell–Scalar theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We analyze the stability of scalarized charged black holes in the Einstein–Maxwell–Scalar (EMS) theory with quadratic coupling. These black holes are labelled by the number of $$n=0,1,2,\ldots $$ n=0,1,2,… , where $$n=0$$ n=0 is called the fundamental ...

Efficient Data Collection in Widely Distributed Wireless Sensor Networks with Time Window and Precedence Constraints

open access: yesSensors, 2017
In addition to the traditional densely deployed cases, widely distributed wireless sensor networks (WDWSNs) have begun to emerge. In these networks, sensors are far away from each other and have no network connections.

MODELLING, SIMULATION AND VISUALIZATION OF A MULTISPECIFIC PHILIPPINE SEAGRASS MEADOW [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Seagrass meadows are constantly under threat from natural and man-made stresses due to its shallow existence in the coastal environment. Restoration and preservation of seagrasses by means of rehabilitation or transplanting strategies is possible, but ...

A Flow-Based Generative Network for Photo-Realistic Virtual Try-on

open access: yesIEEE Access, 2022
Image-based virtual try-on systems aim at transferring the try-on clothes onto a target person. Despite making considerable progress recently, such systems are still highly challenging for real-world applications because of occlusion and drastic spatial ...

Data-Driven Predictive Control With Switched Subspace Matrices for an SCR System

open access: yesIEEE Access, 2022
Selective catalytic reduction (SCR) systems are distributed systems with strong time-varying parameter characteristics such that an accurate model for it is difficult to establish.
