Kinetic subspace investigation using neural network for uncertainty quantification in nonpremixed flamelets by Koenig, Benjamin C, Ji, Weiqi, Deng, Sili

“…However, this one-dimensional assumption does not apply to all flamelet regimes. In the current work, we developed a systematic approach to discover low-dimensional active subspace reductions that apply to the entire mixture fraction space of the flamelet, and that function even in cases where the uncertainty response is not uniform across the entire solution domain and the one-dimensional assumption does not apply. …”

Origin of residual strain in heteroepitaxial films by Postelnicu, Eveline, Wen, Rui-Tao, Ma, Danhao, Wang, Baoming, Wada, Kazumi, Michel, Jurgen, Kimerling, Lionel C

“…The model is expressed in terms of three regimes: (1) misfit control for the low temperature growth regime at 400 °C; (2) point defect control via annealing in the point defect recovery regime at 500–650 °C; and (3) thermal expansion control for growth or anneal at T > 650 °C in the dislocation recovery regime. …”

16.100 Aerodynamics, Fall 2002 by Darmofal, David L.

“…This course extends fluid mechanic concepts from Unified Engineering to the aerodynamic performance of wings and bodies in sub/supersonic regimes. 16.100 generally has four components: subsonic potential flows, including source/vortex panel methods; viscous flows, including laminar and turbulent boundary layers; aerodynamics of airfoils and wings, including thin airfoil theory, lifting line theory, and panel method/interacting boundary layer methods; and supersonic and hypersonic airfoil theory. …”

Dynamics of the sub-Ohmic spin-boson model : a comparison of three numerical approaches by Yao, Yao, Duan, Liwei, Lü, Zhiguo, Wu, Chang-Qin, Zhao, Yang

“…The Davydov D1 ansatz and the time-dependent density matrix renormalization group can both be reliably employed in the weak-coupling regime, while the former is also valid in the strong-coupling regime as judged by how faithfully the trial state follows the Schrodinger ¨ equation. …”

Terahertz-optical intensity grating for creating high-charge, attosecond electron bunches by Lim, Jeremy, Chong, Yidong, Wong, Liang Jie

“…Currently, however, the shortest achievable bunches, at attosecond time scales, have only been realized in the single- or very few-electron regimes, limited by Coulomb repulsion and electron energy spread. …”

Privacy: a political approach by Bogue, RC

“…It can thus be shown that a commitment to democracy entails a commitment to certain privacy rights—a finding that circumvents the difficulty in establishing a common basis for privacy protections by appealing to all citizens who live under democratic regimes. In abandoning familiar understandings of privacy, the political approach to privacy does away with the problematic emphasis on consent, adapts privacy to an ever-changing surveillance environment, addresses prominent critiques of privacy rights, and provides a common basis of justification for future privacy legislation. …”

Nonlinear evolution and acceleration of unstable fuel-lean hydrogen/air flame at normal and cryogenic temperatures by Yang, L, Zhang, T, Wang, Y, Fang, X, Leach, F, Chen, Z

“…By changing the equivalence ratio, initial temperature and channel size, the intensity of DLI and DTI varies, resulting in various regimes of flame evolution. It is found that cryogenic flames are more unstable than normal flames. …”

Temporal evolution of mechanical properties in PDMS: A comparative study of elastic modulus and relaxation time for storage in air and aqueous environment by Zhang, Y, Adam, C, Rehnstrom, H, Contera, S

“…The identification of two distinct relaxation times suggests the involvement of two disparate material property regimes in the relaxation process, implying changes in the surface material composition at the interface with air/water. …”

Engineered terahertz emission from spintronic heterostructures: amplitude, phase and chirality by Agarwal, Piyush

“…The study unlocks a path for a broad class of materials, including topological insulators, Weyl semimetals, and two-dimensional semiconductors, for accessing enhanced interfacial effects. …”

Plan Implementation Challenges in a Shrinking City: A Conformance Evaluation of Youngstown’s (OH) Comprehensive Plan With a Subsequent Zoning Code by Ryan, Brent D., Gao, Shuqi

“…Informants attribute the weak conformance between the comprehensive plan and the Youngstown Redevelopment Code to many of the former’s ideas not being legally defensible. Changing political regimes, shifts in public opinion, and the driving need for economic investment were also cited as contributors to this weak conformance. …”

Envisioning Water: Sustainability and Future-Making in Dubai and Los Angeles by Christidi, Nadia

Mechanics of Three-Dimensional Micro-Architected Interpenetrating Phase Composites by Chen, Andrew Y.

“…Using these prototypes, we study the mechanical behavior of the fabricated composites under uniaxial compression, with particular emphasis on the non-linear and failure regimes. We show that independent of the material system, the presence of a load-bearing matrix distributes the stress in the composite, contributing to a high-strength, globally stretchingdominated failure behavior, regardless of nodal connectivity. …”

A Branched Convolutional Neural Network for Forecasting the Occurrence of Hazes in Paris Using Meteorological Maps with Different Characteristic Spatial Scales by Wang, Chien

“…The strategy is to make the machine learn from available historical data to recognize various regional weather and hydrological regimes associated with low-visibility events. To better preserve the characteristic spatial information of input features in training, two branched architectures have recently been developed. …”

Dynamics of time-modulated, nonlinear phononic lattices by Kim, Brian L., Chong, Christopher, Hajarolasvadi, Setare, Wang, Yifan, Daraio, Chiara

“…In the present work, the response of a one-dimensional phononic lattice with time-periodic elastic properties is studied with experimental, numerical and theoretical approaches in both linear and nonlinear regimes. The system consists of repelling magnetic masses with grounding stiffness controlled by electrical coils driven with electrical signals that vary periodically in time. …”
