An improved statistical wake meandering model
Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort
A new statistical wake meandering (SWM) model is proposed that improves on existing models in the literature. Compared to the existing SWM models, the proposed model has a closed description that does not require simulations to create look-up tables while ...
IOP Publishing2024Improvements to the dynamic wake meandering model by incorporating the turbulent Schmidt number
Fernando Porté Agel, Peter Andreas Brugger, Corey Dean Markfort
Predictions of the dynamic wake meandering model (DWMM) were compared to flow measurements of a scanning Doppler lidar mounted on the nacelle of a utility-scale wind turbine. We observed that the wake meandering strength of the DWMM agrees better with the ...
2024Wave-momentum shaping for moving objects in heterogeneous and dynamic media
Romain Christophe Rémy Fleury, Matthieu Francis Malléjac, Bakhtiyar Orazbayev, Stefan Rotter
Light and sound waves can move objects through the transfer of linear or angular momentum, which has led to the development of optical and acoustic tweezers, with applications ranging from biomedical engineering to quantum optics. Although impressive manip ...
2024Model-based constraints for trajectory determination of quad-copters: Design, calibration & merits for direct orientation
Jan Skaloud, Davide Antonio Cucci, Kenneth Joseph Paul
This paper proposes a novel method to improve georeferencing of airborne laser scanning by improved trajectory estimation using Vehicle Dynamic Model. In Vehicle Dynamic Model (VDM), the relationship between the dynamics of the platform and control inputs ...
2023Third-harmonic generation monitoring of femtosecond-laser-induced in-volume functional modifications
Christian Enz, Yves Bellouard, Assim Boukhayma, Andrea Kraxner, Olivier Bernard
During the last two decades, ultrafast in-volume laser-based processing of transparent materials has emerged as a key 3D-printing method for manufacturing a variety of complex integrated photonic devices and micro-parts. Yet, identifying suitable laser pro ...
2023A chip-scale second-harmonic source via self-injection-locked all-optical poling
Tobias Kippenberg, Camille Sophie Brès, Marco Clementi, Junqiu Liu, Edgars Nitiss
Second-harmonic generation allows for coherently bridging distant regions of the optical spectrum, with applications ranging from laser technology to self-referencing of frequency combs. However, accessing the nonlinear response of a medium typically requi ...
2023Recent progress in alkynylation with hypervalent iodine reagents
Jérôme Waser, Eliott Hugo Joran Le Du
Although alkynes are one of the smallest functional groups, they are among the most versatile building blocks for organic chemistry, with applications ranging from biochemistry to material sciences. Alkynylation reactions have traditionally relied on the u ...
ROYAL SOC CHEMISTRY2023On the benefit of concurrent adjustment of active and passive optical sensors with GNSS & raw inertial data
Jan Skaloud, Davide Antonio Cucci, Kyriaki Mouzakidou
In airborne laser scanning a high-frequency trajectory solution is typically determined from inertial sensors and employed to directly geo-reference the acquired laser points. When low-cost MEMS inertial sensors are used, such as in lightweight unmanned ae ...
2022Dual chirped microcomb based parallel ranging at megapixel-line rates
Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Anton Lukashchuk
Photonic integrated systems can be harnessed for fast and efficient optical telecommunication and metrology technologies. Here the authors develop a dual-soliton microcomb technique for massively parallel coherent laser ranging that requires only a single ...
NATURE PORTFOLIO2022Tailored deformation behavior of 304L stainless steel through control of the crystallographic texture with laser-powder bed fusion
Roland Logé, Christian Leinenbach, Efthymios Polatidis, Markus Strobl
Laser-powder bed fusion (L-PBF) has gained significant research interest, not only for its profound advantage of producing near-net shape complex geometries of metallic parts, but also for the possibility of producing tailored microstructures. Here we expl ...
