Bees "Surf" Atop Water

11-20-19

Chris Roh, Research Engineer, working with Professor Morteza Gharib, discovered a unique way that bees navigate the interface between water and air. When a bee lands on water, the water sticks to its wings, robbing it of the ability to fly. However, that stickiness allows the bee to drag water, creating waves that propel it forward."I was very excited to see this behavior and so I brought the honeybee back to the lab to take a look at it more closely," Roh says.

Professor McKeon Unlocked Secrets Behind Turbulence

11-06-19

Beverley McKeon, Theodore von Karman Professor of Aeronautics, has unlocked some of the secrets behind turbulence, a much-studied but difficult-to-pin-down phenomenon that mixes fluids when they flow past a solid boundary. "We knew that, underlying these very complicated structures, there had to be a very simple pattern. We just didn't know what that pattern was until now," says McKeon. [Caltech story]

New Polymer Heart Valve Implanted in First Patient

09-18-19

Professor Morteza Gharib, has designed a new generation of heart valves that are longer-lasting, cost less to manufacture, and are more biocompatible than options that are currently available to patients. One of the new valves has been implanted into a human for the first time. "This is among my proudest moments. Creating something with the potential to save and improve lives is one of the reasons I became an engineer," Gharib says. [Caltech release]

CAST Awards Seed Funding to Three New Projects

08-21-19

Caltech Center for Autonomous Systems and Technologies (CAST) has awarded seed funding to three new collaborative projects. The first project was proposed by Aerospace postdoctoral scholar H. Jane Bae, along with Professors McKeon, Tropp, and Meiron. It aims to develop algorithms to predict the onset of extreme events in real time thus allowing autonomous air vehicles to avoid or compensate for the rough turbulent airflow. The second project was proposed by Professors Effros, and Murray and will focus a new approach to the analysis, design, and implementation of complex, networked systems with the goal of optimizing latency in information sharing. The third project was proposed by Professor Thompson and JPL colleagues I. Fenty, R. Castano, D. Limonadi, and G. Woodward. This project plans to take a step towards developing autonomous observing arrays that will use ocean robotics to deploy ice melt-rate instruments within ice shelf cavities.

Best Student Paper Award at International Workshop

07-23-19

The paper "Distributed multi-target relative pose estimation for cooperative spacecraft swarm" co-authored by GALCIT students Kai Matsuka, Sorina Lupu, Yashwanth Kumar Nakka, and Rebecca Foust, as well as Professor Soon-Jo Chung and JPL Chief Technologist, Dr. Fred Hadaegh has won one of the two Best Student Paper awards at the 2019 International Workshop on Satellite Constellations and Formation Flying (IWSCFF). The paper presents a multi-agent localization algorithm architecture applied to a large-scale spacecraft swarm. The proposed algorithm is verified by simulation and robotic experiments using the air-bearing spacecraft simulators. The team also acknowledged the work of two Caltech undergraduate students Aaron Feldman and Jennifer Sun for their contribution to the robotic experiments. [Read the paper]

Professor Gharib Constructs Leonardo da Vinci's Model of Flow

07-16-19

Leonardo da Vinci studied the motion of blood in the human body. He was interested in the heart’s passive, three-cusp aortic valve, which he realized must be operated by the motion of blood. He theorized that vortices curl back to fill the cusps in the flask-shaped constriction at the aorta’s neck. Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Bioinspired Engineering; Booth-Kresa Leadership Chair, Center for Autonomous Systems and Technologies; Director, Graduate Aerospace Laboratories; Director, Center for Autonomous Systems and Technologies, has used modern imaging techniques to demonstrate the existence of the revolving vortices that Leonardo interpreted as closing the valve.
