This paper presents a fully autonomous micro aerial vehicle (MAV) developed to pop balloons using onboard sensing and computing. The system was evaluated at the Mohamed Bin Zayed International Robotics Challenge (MBZIRC) 2020. The MAV successfully popped all five balloons in under two minutes in each of the three competition runs. Why it matters: This demonstrates the potential of autonomous robotics and computer vision for real-world applications in challenging environments.
KAUST collaborated with NASA's Langley Research Center to launch six weather balloons from KAUST's Coastal & Marine Laboratory, reaching an altitude of 35 kilometers. The balloons were equipped with instruments to measure meteorological properties and characterize the optical properties of aerosols, including a Compact Optical Backscatter Aerosol Detector (COBALD). The research focuses on understanding the impact of dust aerosols on the Arabian Peninsula, including their effects on climate, air quality, and solar energy. Why it matters: This collaboration advances understanding of atmospheric aerosols in the region, with implications for climate modeling, solar energy efficiency, and Red Sea ecosystems.
KAUST held its 2016 Winter Enrichment Program (WEP) Science Fair, featuring science shows and exhibits for children from The KAUST School (TKS) and local schools. Demonstrations included hydroponics, aquaponics, and experiments on plant salt stress. TKS students presented research on handwashing and CO2 levels. Why it matters: Such events promote STEM education and engagement within the KAUST community and surrounding areas.
John Pantoja from the Directed Energy Research Center at TII presented a method to estimate the effects of high current impulses on electro-conductive textiles. The method uses specific action, a parameter to determine burst of exploding wires, and a new equivalent electrical circuit. The model estimates the current intensity needed to melt the conductive layer at contact areas between yarns, and is validated experimentally on ripstop woven fabrics. Why it matters: The research explores conductive fabrics for portable lightning protection shelters, potentially reducing lightning-related accidents in high-risk populations.
Pong C Yuen from Hong Kong Baptist University will present a talk on remote photoplethysmography (rPPG) detection. The talk will review the development of rPPG detection, share recent research, and discuss future directions. rPPG is a technology for non-contact computer vision and healthcare applications like heart rate estimation. Why it matters: Advancements in rPPG could enable new remote patient monitoring and diagnostic tools in the region, reducing the need for physical contact.
KAUST is hosting a double lecture event featuring the International Symposium on Porous Organic Polymers (POPs) and the KAUST Workshop for Women in Science and Engineering (WISE). Speakers include professors from Imperial College, McGill University, Sorbonne University, and the University of Augsburg, as well as representatives from KAUST and AEON Strategy. The event will focus on porous materials and highlight women's accomplishments in science and engineering. Why it matters: Promoting gender diversity and showcasing scientific advancements at KAUST can help strengthen Saudi Arabia's research ecosystem and inspire future generations of scientists.
Dr. Zeke Xie from HKUST(GZ) presented research on noise initialization and sampling strategies for diffusion models. The talk covered golden noise for text-to-image models, zigzag diffusion sampling, smooth initializations for video diffusion, and leveraging image diffusion for video synthesis. Xie leads the xLeaF Lab, focusing on optimization, inference, and generative AI, with previous experience at Baidu Research. Why it matters: The work addresses core challenges in improving the quality and diversity of generated content from diffusion models, a key area of advancement for AI applications in the region.
