The study introduces the Qatar University Dual-Machine Bearing Fault Benchmark dataset (QU-DMBF) containing sound and vibration data from two motors across 1080 conditions. It proposes a deep learning approach for sound-based fault detection, addressing limitations of vibration-based methods. Experiments on QU-DMBF show sound-based detection is more robust, independent of sensor location, and cost-effective while matching vibration-based performance. Why it matters: The new dataset and findings could shift the focus toward sound-based methods for more reliable and accessible predictive maintenance in industrial settings.
KAUST's Clean Combustion Research Center (CCRC) hosted the Combustion in Extreme Conditions research conference from March 5-8. The conference focused on combustion under extreme conditions in modern engines, covering high-pressure combustion, advanced diagnostics, and high-performance computations. Experts from academia, national labs, and industry discussed global collaborations toward clean combustion systems, alternative fuels, and emission reduction techniques. Why it matters: The conference highlights KAUST's role as a global hub for combustion research and its commitment to advancing technologies for cleaner and more efficient energy solutions.
KAUST and GE have partnered to study the feasibility of using crude oils like Arabian Super Light (ASL) to power heavy-duty gas turbines. The collaboration aims to develop turbines capable of burning crude oil directly from the ground to meet Saudi Arabia's energy security needs. The research involves building a rig at KAUST's High Pressure Combustion Laboratory (HPCL) to conduct corrosion tests on turbine materials by burning ASL/AXL crude continuously for 2,000 hours. Why it matters: This partnership could reduce reliance on natural gas and offer an economically viable alternative fuel source, bolstering energy security in Saudi Arabia and potentially influencing turbine technology worldwide.
The 2017 KAUST Research Conference focused on new combustion concepts, bringing together experts from academia, national labs, and industry. Participants discussed various aspects of combustion, including energy conversion by Professor Igor Adamovich from Ohio State University. Anne Bourdon from École Polytechnique presented on plasma-assisted applications. Why it matters: The conference facilitated knowledge exchange and collaboration on advancing combustion technologies, a field relevant to energy and environmental sustainability in the region.
KAUST Professors William Roberts and Robert Dibble were inducted as Fellows of The Combustion Institute (CI) in February. Roberts was recognized for his work on laminar flames, turbulent combustion, and soot formation at elevated pressures. Dibble was inducted for exceptional contributions to developing and using laser diagnostics for combustion research. Why it matters: This recognition highlights KAUST's contributions to combustion research and strengthens its position as a leading institution in the field, attracting top students and researchers.
A talk at the Directed Energy Research Center (DERC) at TII will discuss rapid prototyping using laser-cutting facilities available at MakerSpace in Al Zeina. The talk will cover constructing prototypes from wood and acrylic and compare this approach to traditional 3D printing. The speakers will also describe the impact of the ‘4th Industrial Revolution’ on manufacturing in the UAE, and how makerspaces can contribute to Operation 300bn. Why it matters: This highlights the UAE's focus on advanced manufacturing and the role of makerspaces in fostering innovation and developing local capabilities.
The Directed Energy Research Center (DERC) is partnering with Montena Technology to study high-altitude electromagnetic pulses and design infrastructure safeguards. DERC is also collaborating with Radaz to evaluate ground penetrating and synthetic aperture radars in Abu Dhabi, aiming to identify natural resources. Additionally, DERC and Université de Picardie Jules Verne are working on laser sources and sensors, with a DERC researcher spending four years in France. Why it matters: These partnerships enhance DERC's research capabilities in critical areas like infrastructure protection, resource exploration, and advanced sensing technologies.
KAUST researchers developed a laser-based sensor that exploits the "chirp" phenomenon in semiconductor lasers to accurately measure gas temperature in combustion systems. The sensor uses spectroscopic measurements at very fast rates (1.0 MHz) and can measure temperature at the nanosecond timescale at repetition rates of thousands of kHz. The new sensor reduces uncertainty compared to previous methods and works rapidly in transient shock tube experiments. Why it matters: This in-house development provides a non-invasive, accurate, and easily implementable system for combustion research, with implications for understanding and improving energy efficiency.
