Parallel Ray Tracing of Black Hole Images Using the Schwarzschild Metric
Liam Naddell, Marcelo Ponce
Rendering images of black holes by utilizing ray tracing techniques is a common methodology employed in many aspects of scientific and astrophysical visualizations. Similarly, gene…
An Open-Source Framework to Emulate Delay and Disruption Tolerant Networks for International Space Station Communication
Krit Grover, Marcelo Ponce
Delay and Disruption Tolerant Networks (DTN) are critical for reliable communications in challenged network environments, particularly for space systems where end-to-end connectivi…
Bridging the Educational Gap between Emerging and Established Scientific Computing Disciplines
Marcelo Ponce, Erik Spence, Ramses van Zon +1
In this paper we describe our experience in developing curriculum courses aimed at graduate students in emerging computational fields, including biology and medical science. We foc…
Synchronizability of chaotic logistic maps in delayed complex networks
Marcelo Ponce, C. Masoller, Arturo C. Marti
We study a network of coupled logistic maps whose interactions occur with a certain distribution of delay times. The local dynamics is chaotic in the absence of coupling and thus t…
Cybersecurity Training for Users of Remote Computing
Marcelo Ponce, Ramses van Zon
End users of remote computing systems are frequently not aware of basic ways in which they could enhance protection against cyber-threats and attacks. In this paper, we discuss spe…
Seeking for toroidal event horizons from initially stationary BH configurations
Marcelo Ponce, Carlos Lousto, Yosef Zlochower
We construct and evolve non-rotating vacuum initial data with a ring singularity, based on a simple extension of the standard Brill-Lindquist multiple black-hole initial data, and…
