Ethanol solutions are present in many industries, including the beverage, medical, and fuel industries.While electrical methods for measuring ethanol concentration subject to electromagnetic interference, may require large amounts of solution, or take a long time, optical techniques based on fiber optics immune chemically inert, can deliver signals over distances with minimal noise.However, optic sensors often expensive equipment manufacture, e.g. CO 2 laser manufacturing Bragg gratings,...
Convolutional neural networks (CNNs) are widely used for image classification; however, setting the appropriate hyperparameters before training is subjective and time consuming, search space not properly explored. This paper presents a novel method automatic architecture based on an estimation of distribution algorithm (EDA) binary classification problems. The were coded in form due to nature metaheuristics stage CNN architectures which was performed using Boltzmann Univariate Marginal...
Reproducing the results from a scientific paper can be challenging due to absence of data and computational tools required for their analysis. In addition, details relating procedures used obtain published difficult discern use natural language when reporting how experiments have been performed. The Investigation/Study/Assay (ISA), Nanopublications (NP), Research Objects (RO) models are conceptual modelling frameworks that structure such information papers. Computational workflow platforms...
In this letter, symmetric and asymmetric core-offset Mach-Zehnder interferometer (MZI) torsion sensors based on a single mode fiber (SMF) are presented. Here, three different MZIs were implemented their interference patterns characteristics have been experimentally investigated. our devices, the maximum sensitivities 6x10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> , 12x10 23x10 nm/°, with possibility to discriminate between...
An all-fiber Fabry-Perot (FP) interferometer is proposed and validated by the arc splicing technique. By using conventional fiber special hollow-core photonic crystal fiber, several FP cavities were formed at tip discharges. As a result of interaction between these cavities, modified principle operation was obtained; temperature, refractive index, load analyses this modification. In addition, presents good resolution sensitivity in each parameter examined. The structure offers compactness,...
There are various issues that limit the development and deployment of new software solutions in cancer image analysis research. In this paper we discuss some these propose a framework design based on cloud computing concepts, Microsoft technologies, existing middleware imaging toolkits. Furthermore, address by introducing collaborative visual tools for input data multi-user interactions.
The accurate and efficient segmentation of coronary arteries in X-ray angiograms represents an essential task for computer-aided diagnosis. This paper presents a new multiscale Gaussian-matched filter (MGMF) based on artificial neural networks. proposed method consists two different stages. In the first stage, MGMF is used detecting vessel-like structures while reducing image noise. results are compared with those obtained using six GMF-based detection methods terms area (<mml:math...
This paper presents a new method based on Estimation of Distribution Algorithms (EDAs) to detect parabolic shapes in synthetic and medical images. The computes virtual parabola using three random boundary pixels calculate the constant values generic equation. resulting is evaluated by matching it with shape input image Hadamard product as fitness function. proposed terms computational time compared two implementations generalized Hough transform RANSAC for detection. Experimental results...
In this letter, a switchable ytterbium doped double cladding photonic crystal fiber (Yb-doped-DCPCF) laser based on three optical path Mach-Zehnder interferometer (MZI) is presented. Here, the MZI with three-beam was achieved by fusion splicing segment of an Yb-doped-DCPCF between two pieces single mode fibers. Moreover, in proposed arrangement, acting simultaneously as and also gain medium. This can be switched to emit or line controlling polarization state it operates within range from...
The "Virtual Research Environment for Cancer Imaging" project aims to support image processing researchers and clinicians by providing a framework sharing images algorithms. In this paper we present the system developed date which has focused on managing DICOM using Microsoft's Share Point 2010. allows configuring metadata be extracted from tags meet requirements both set of users: imaging clinicians. We work conducted allow algorithms as scientific workflows through use Trident Workflow...
Providing timely and meaningful feedback of programming assignments to students is very important ensure a smooth learning curve. However, this can be time-consuming task for teachers instructors. There are some tools that already provide support grading assignments, integrated with management systems allow teaching staff manage all information in more effective way. In work, an analysis automatic Moodle carried out. A comparison these presented one them tested recommended its future...
In multidisciplinary team (MDT) meetings for colorectal and liver cancer, each patient case is reviewed while evidence, including digital image scans such as MRI PET/CT, presented by clinicians. Currently these images are projected onto a wall, limiting clinician interaction. While multi-touch interactive tabletops have been used to enhance collaboration in various scenarios, some aspects quality touch resolution need be evaluated this particular scenario. paper we present the results of...
