Saez Ortuño, M.A. (author), Yin, F. (author), Gangoli Rao, A. (author), Vos, Roelof (author), Proesmans, P. (author)As climate change aggravates, the aviation sector strives to minimize its climate footprint. To this end, international organizations, such as ICAO and ACARE, are promoting mitigation measures including novel technologies, operations, and energy carriers to reduce aircraft emissions significantly. Hydrogen (H2) as an alternative fuel has the...conference paper 2023

Radhakrishnan, Kaushik (author), Deck, K.T. (author), Proesmans, P. (author), Linke, Florian (author), Yin, F. (author), Grewe, V. (author), Vos, Roelof (author), Lührs, Benjamin (author), Niklaβ, Malte (author), Dedoussi, I.C. (author)The aircraft’s environmental performance on fleet level is so far completely decoupled from the design process. The climate impact from aviation arising from non-CO2 effects are largely independent from CO2 emissions, but rather depend on the atmospheric state. Previously complex climate-chemistry models were used to evaluate the non-CO2...conference paper 2022

Wang, Zhongkai (author), Choi, Minsoo (author), Wright, John (author), Lee, Kyoungtae (author), Liu, Zhaokai (author), Yin, Bozhi (author), Han, Jaeduk (author), Du, S. (author), Alon, Elad (author)We present a ring-oscillator-based sub-sampling phase-locked loop (PLL) using a generator-based design flow. A hybrid loop with a delta-sigma ($\Delta \Sigma$) modulator is applied to reduce the loop filter (LF) area and the control ripple. The generator automatically produces the ring oscillator and PLL to meet the provided specifications. The...conference paper 2022

Blondeel, Tim (author), Yin, F. (author), Gangoli Rao, A. (author)The fuel efficiency of turbofan engines has improved significantly, hence reducing aviation's CO2 emissions. However, the increased operating pressure and temperature for fuel efficiency cause adverse effects on NOx emissions. Therefore, a novel engine concept, which can reduce NOx emissions without affecting the cycle efficiency, is of high...conference paper 2022

Yin, Jiapeng (author), Unal, Christine (author), Russchenberg, Herman (author)Nowadays, there is an intensive use of wind turbines worldwide to generate green and renewable energy. In addition, the sizes of wind turbines keep increasing for higher efficiency. However, echoes from wind turbines are severe clutter for weather radar, deteriorating its performance significantly. In this work, the spectral polarimetric filters...conference paper 2018

Yin, J. (author), Unal, C.M.H. (author), Russchenberg, H.W.J. (author)For the polarimetric-Doppler weather radar, sometimes there are artifacts caused by radar system itself or external sources displaying in the radar plan position indicator (PPI). These artifacts are not confined to specific range bins and also they are non-stationary when observed in the Doppler domain. This paper puts forward a method to...conference paper 2017
