3D Discrete Element Method (DEM) with induced electrostatic cohesion

By Daniel Bustamante

Granular materials can acquire electrostatic charges during collisions in various industrial processes. The present work is dedicated to the mechanical simulation of granular media using a method of discrete cohesive elements. It is a model based on packages composed of three-dimensional grains of arbitrary shape obtained from real samples by combining X-ray computerized tomography (3DXRCT) and mathematical functions called level sets. The electrostatic cohesion is introduced in the scale of the particles by incorporating an electric charge density on the surface of the grains. The effect of the introduction of electrostatic cohesion is visualized by the construction of Mohr circles in which an axial compression process is carried out on the packing, while the walls of this packing are kept at different confining pressures.

Analytical study of slope stability in dry, cohesionless 2D granular media

By Fabian

We study, from an analytical point of view, the inter-particle interactions in dry, cohesionless 2D granular media to find the micromechanical origin of landslides. Our analytical study is compared to the results of numerical simulations of granular materials in a rotating tumbler. These simulations are based on a contact dynamics method.

3D Image processing: image segmentation and recognition using neural networks

By Kuntur Mallku Muenala Terán

The study and understanding of soil behavior involve the use of highly expensive equipment in the laboratory. Furthermore, obtaining soil samples for study in these laboratories involves complex and laborious procedures, in addition to the difficult accessibility that present some places where samples are made. For these reasons and considering the great computational development of the last decades, creation of a digital database of soils that will allow computational simulation of all procedures performed in laboratories, as well as natural phenomena such as landslides and subsidence due to geological faults, is proposed. It in turn will help prevent risks related to infrastructure damage and loss of life.

3D models of construction materials

By Manolo Noboa

Medical devices, specially the ones used for tomography, are extremely expensive, because they must be highly precise and secure. For the same reason, they are constantly changed for more actual models, and the old devices are deposited in warehouses. Even though, they are still functional, and their capacities are stull useful in other fields. That’s how this project arises, proposing the reuse of one of these devices, adapting it so it is able to generate 3D models of construction materials.

A hybrid backanalysis algorithm for calibration of DEM parameters against experimental results

By Sebastian Pazmiño

In this project, the implementation and combination of genetic algorithms (GA), principal component analysis (PCA) and gradient-based methods (GBM) with which to explore and find the global minimum (if there is one) have been proposed. ) of a given objective function for the calibration of the parameters of a computational scheme of discrete elements (3DLS-DEM), in such a way that the error between the results of the computational form is minimized using 3DLS-DEM and the results means of A true laboratory experiment.

Isogeometric analysis for the description of a surfactant spreading in a thin liquid film

By David Medina

The study of the spreading of surfactants is well known in many industrial and medical applications. This topic is important to improve efficiency of the coating by surfactants because of the non-uniform coating present in both soluble and insoluble surfactants in liquid films. The complexity in the physics and the experiments forced researchers to use the aid of computational tools and many works have been performed using numerical simulations.

My passion and what I actually do for a living is doing scientific research in mathematical modeling and numerical methods. I got my PhD in Applied Mathematics and Mechanics at Caltech (California Institute of Technology) where I also had the opportunity of getting a grant with NASA to design and build a tool for sampling Martian and celestial bodies regolith. I am interested in problems at the interface of physics and mechanics.
I obtained the BSc in Earth Sciences. ". In 2008 I obtained a Master's Degree in Geological Science at the Faculty of Earth Sciences of Cagliari My doctoral thesis is entitled: "Depositional and welding processes in low aspect ratio ignimbrites: examples from the Sulcis Volcanic District (Sardinia, Italy)" (Tutor Prof. Dr. Raffaelo Cioni). After I conclude my doctorate, I followed the master course "VULCAMED" on geophysical and volcanic monitoring processes at the National Institute of Geophysics and Volcanology (INGV) in Naples.
My research focuses on repairing an old medical tomography device and reusing it for taking 3D images of real shapes of soils in granular scale. Before I joined INSπRE, I was a student of Alex X. Jerves class in San Francisco University, where I am studying computer science. In my spare time, I make phone apps, develop solutions for other projects, offer other students tutorships, watch anime and play videogames.
My research focuses on developing a mathematical algorithm in Alex X. Jerves' group and validating this model with a simulation that uses the Discrete Element Method and real shapes of soils in granular scale. Before I joined INSπRE, I went to San Francisco de Quito University where I am pursuing a graduate degree mathematics with a minor in psychology. In spare time I enjoy solving problems, watching anime, playing video games and learning about computers.
I do research at INSπRE with my coworker Rubén A. Jerves and our tutor Alex X. Jerves. We study, from an analytical point of view, the micromechanical interactions on granular media that give rise to a macro mechanical phenomenon: the landslides. Our results are compared to numerical simulations performed with the Contact Dynamic Method. I am a civil engineer and met Alex’s group when I was studying at Universidad de Cuenca. I spend my free time doing sports and trying to learn new things every day.
I am working to introduce the phenomenon of electrostatic cohesion that occurs in the modeling of granular materials such as dusts, powders and clays, through a Discrete Element Method that uses arbitrary shapes of three-dimensional grains. While I am working on this for INSπRE, I am getting my bachelor’s degree in physics at Universidad San Francisco de Quito. I enjoy investing my spare time reading about quantum field theory, plasmonics, cosmology, and algebraic topology.
My research focuses on the implementation of genetic algorithms, principal components analysis and gradient based methods to calibrate 3DLSDEM simulation parameters to compare the computational results against experimental. I am a current student of chemical engineering at ESPOL. In my spare time i like to read about new advances on physics and chemistry, new materials and engineering process.
I'm currently studying petroleum engineering at Escuela Superior Politécnica del Litoral (ESPOL) where I first came across INSPIRE. I'm also working with Prof. Jerves on the second edition of his book "Elements of Numerical Calculus". On my spare time I like reading about oil-industry related stuff, listen to music and play video games.
I am a Professor at Universidad San Francisco de Quito (USFQ), who is interested in the development of analytical and numerical models for Earthquake Engineering with an emphasis on Performance-Based Earthquake Engineering.
Professor at ESPOL in basic inferential statistics and geology courses for oil engineers; I also teach biostatistics at UEES; I have a bachelor degree in Geological Engineering and graduate studies in Productivity and Quality Management at ESPOL, I write articles in areas such as Social Sciences (analyzed correlations between studies of psychosocial risks, job satisfaction, engagement, occupational diseases, among others) and applied Geology for the oil industry; I play sports, especially table tennis and soccer.
I'm a engineer with strong Linux networking skills. I obtained my master's degree on Telecommunications at Florida International University. Since then I've been working on my startup company and also as an University researcher and professor. My current research is focused on Human - Computer Interaction and Software Defined Networks. In my spare time I enjoy listening to music and going to the gym.
