This paper presents an automatic system for the quality control of metallic components using a photometric stereo-based sensor and a customized semantic segmentation network. This system is designed based on interoperable modules, and allows capturing the knowledge of the operators to apply it later in automatic defect detection. A salient contribu...

Leak detection is a common and relevant step of manufacturing processes, which takes place throughout the production line. While several leak test methods have been proposed, pressure decay testing is still widespread due to its lower cost, simplicity and sensitivity in relatively small volumes. However, pressure decay testing is very sensitive to...

One of the main objectives of Industry 4.0 (I4.0) is to generate new opportunities based on the convergence of traditionally isolated technologies such as industrial control systems (ICSs) and information and communication technology (ICT). This presents new opportunities to take advantage of ICT technologies to develop new applications and service...

In the context of numerical methods, the problem of frequency-domain (spectral) simulations is crucial for the solution of Partial Differential Equations. Fast Fourier Transform (FFT) algorithms significantly reduce the computational cost of such simulations and enable parallelization using Graphics Processing Units (GPUs). In the particular subdom...

In flexible manufacturing systems, fast feedback from simulation solutions is required for effective tool path planning and parameter optimization. In the particular sub-domain of laser heating/cutting of thin rectangular plates, current state-of-the-art methods include frequency-domain (spectral) analytic solutions that greatly reduce the required...

Due to a lack of ubiquitous tools for volume data visualization, 3D rendering of volumetric content is shared and distributed as 2D media (video and static images). This work shows how using open web technologies (HTML5, JavaScript, WebGL and SVG), high quality volume rendering is achievable in an interactive manner with any WebGL-enabled device. I...

Interactive multi-beam laser machining simulation is crucial in the context of tool path planning and optimization of laser machining parameters. Current simulation approaches for heat transfer analysis (1) rely on numerical Finite Element methods (or any of its variants), non-suitable for interactive applications; and (2) require the multiple lase...

In the context of computer numeric control (CNC)-based sheet metal laser cutting, the problem of heat transfer simulation is relevant for the optimization of CNC programs. Current physically based simulation tools use numeric or analytic algorithms which provide accurate but slow solutions due to the underlying mathematical description of the model...

Recent developments in Web-based volume rendering have gained recognition by Web users and professionals in several fields. The ISO-IEC Standard Extensible 3D (X3D) version 3.3 specifies the integration and visual styling of volumetric data for real-time interaction. The specification is an important milestone describing a framework for expressive...

We present a real-time volume rendering component for the Web, which provides a set of illustrative and non-photorealistic styles. Volume data is used in many scientific disciplines, requiring the visualization of the inner data, features for enhancing extracted characteristics or even coloring the volume. The Medical Working Group of X3D published...

Recently the possibility to visualize interactively volumetric datasets in the Web has opened new methods of exploration and sharing of 3D images coming from different fields. At the same time, VR technologies are gaining momentum in the society, where several HMD’s are ready to be bought. This paper presents how volumetric datasets represented as...

This paper presents three required functionality when volume datasets are aimed to be visualized in ubiquitous platforms: (i) support of segmented volume datasets, (ii) navigation inside the volume and (iii) direct visualization of DICOM datasets. DICOM is the de-facto standard in the medical imaging field. The results shows that these functionalit...

Volume rendering is a visualization technique focused in volumetric datasets, which requires a great amount of computational power and memory resources. This situation is even more severe when HTML5 and WebGL implementations are used in ubiquitous platforms to render the virtual scene. This paper presents a WebGL based volume rendering algorithm to...

Virtual Reality training for fire fighters and managers has two main advantages. On one hand, it supports the simulation of complex scenarios like big cities, where a fire cannot be simulated in the real world. On the other hand, fire fighting VR simulators allow trainees to experience situations as similar as possible to real fire, reducing the pr...
