3D Data Fusion

Model Fusion under Probabilistic and Interval Uncertainty, with Application to Earth Sciences

One of the most important studies of the earth sciences is that of the Earth's
interior structure. There are many sources of data for Earth tomography models:
first-arrival passive seismic data (from the actual earthquakes),
first-arrival active seismic data (from the seismic experiments),
gravity data, and surface waves. Currently, each of these datasets is
processed separately, resulting in several different Earth models that have
specific coverage areas, different spatial resolutions and varying degrees of

Relocating San Miguel Volcanic Seismic Events for Future Velocity and Tomographic Models

The San Miguel volcano lies near the city of San Miguel, El Salvador (13.43N and -88.26W). San Miguel volcano is an active volcano and presents a significant natural hazard for the city of San Miguel. Furthermore, the internal state and activity of active volcanoes remains an important component to understanding volcanic hazard. The main technology for addressing volcanic hazards and processes is through the analysis of data collected from the deployment of seismic sensors that record ground motion.

Towards a Fast, Practical Alternative to Joint Inversion of Multiple Datasets: Model Fusion

In many areas of science and engineering, we have different sources of data. For example, in geophysics, there are many sources of data for Earth models: First-arrival passive seismic data (from the actual earthquakes), first-arrival active seismic data (from the seismic experiments), gravity data, etc. Datasets coming from different sources provide complementary information. In general, some of the datasets provide better accuracy and/or spatial resolution in some spatial areas and in some depths, while other

The Notion of the Quasicentral Path in Linear Programming

Our objective in this work is to show that a related notion called the quasicentral path (QCP), introduced by Argáez and Tapia [2, 3] in
nonlinear programming, while being a less restrictive notion it is
sufficiently strong to guide the iterates towards a solution of the Linear Programming problem.

Crustal Modeling SAW

Abstract workflow about the process of creating a 2D crustal model of the subsurface of the Earth. The process uses receiver function data, gravity data, and magnetic data to create the model. The field of application is Geophysics. This process was originally documented by Dr. Randy Keller, and later refined by Dr. Musa Hussein.
