Machine Learning for Cybersecurity: Network-based Botnet Detection Using Time-Limited Flows

Author: Stephanie Ding Mentor: Julian Bunn Editor: Sherry Wang Abstract Botnets are collections of connected, malware-infected hosts that can be controlled by a remote attacker. They are one of the most prominent threats in cybersecurity, as they can be used for a wide variety of purposes including denial-of-service attacks, spam or bitcoin mining. We propose … Continue reading Machine Learning for Cybersecurity: Network-based Botnet Detection Using Time-Limited Flows

Development and Implementation of Captive Trajectories in the NOAH Water Tunnel Laboratory

Abstract: The NOAH Water Tunnel Laboratory is currently used to improve our understanding of various aspects of turbulence and fluid mechanics. The goal of this project is to understand the capabilities of a newly installed technology and the opportunities it presents for enhancing the the use of the NOAH Laboratory in the future. The recently installed Captive Trajectory System (CTS) , a cyber-mechanical system capable of moving and rotating within the water tunnel, allows us to explore new methods of simulating objects moving in complex, turbulent fluids. By harnessing the ability to program how the CTS behaves, the system was shown effective in modeling the motion of an object in real time as variable forces were applied to it. Through simple, controlled examples, we discovered the ability of the CTS to accurately model various types of motion, such as that of a mass-spring-damper system, or a planet orbiting a sun. In more complex examples, the CTS was able to simulate the general behavior of an airfoil in the wake of a cylinder with vortex shedding. The examples explored over the course of the project have proven that the CTS can be used as a useful experimental tool and will open the door to new methods of studying turbulence and unsteady aerodynamics in the future.

Eye Measurements as Objective Measures of Flow Experience

Author: Salma Elnagar Mentors: Shinsuke Shimojo and Mohammad Shehata Editor: Jagath Vytheeswaran Abstract Flow experience is achieved when a person is said to be “in the zone” as they achieve a fit between skill-and-challenge level in a certain activity. Many of these activities, such as video games, music, or athletic competitions, involve the participation or … Continue reading Eye Measurements as Objective Measures of Flow Experience

Development of a Virtual Reality Platform for the Study of Human Behavior

Author: Natalia Brody, Emory University, Class of 2019 Project Partner: Luca Donini, University of Cambridge Mentors: Ralph Adolphs, Ph.D. and Juri Minxha, Caltech Abstract In the past, neuroscientists have used a single experimental paradigm to study the way we interact with and process the world around us: a subject is shown a stimulus while some … Continue reading Development of a Virtual Reality Platform for the Study of Human Behavior
