Ricci flow coupled with harmonic map flow [PDF]
, 2011 We investigate a new geometric flow which consists of a coupled system of the Ricci flow on a closed manifold M with the harmonic map flow of a map phi from M to some closed target manifold N with a (possibly time-dependent) positive coupling constant ...

FLOW INSTABILITY IN A BAFFLED CHANNEL FLOW [PDF]
Journal of computational fluids engineering, 2011 Abstract Flow instability in baffled channel flow, where thin baffles are mounted on both channel walls periodically in the direction of the main flow, has been numerically investigated. The geometry considered here can be regarded as a simple model for finned heat exchangers.

Analyticity and the Unruh effect: a study of local modular flow [PDF]
Journal of High Energy PhysicsThe Unruh effect can be formulated as the statement that the Minkowski vacuum in a Rindler wedge has a boost as its modular flow. In recent years, other examples of states with geometrically local modular flow have played important roles in understanding

, 2018 In this paper we propose an in-depth analysis of a method, called the flow network method, which associates with any network a complete and quasi-transitive binary relation on its vertices.

Modal and nonmodal stability analysis of electrohydrodynamic flow with and without cross-flow [PDF]
, 2015 We report the results of a complete modal and nonmodal linear stability analysis of the electrohydrodynamic flow (EHD) for the problem of electroconvection in the strong injection region.

PWC-Net: CNNs for Optical Flow Using Pyramid, Warping, and Cost Volume [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 We present a compact but effective CNN model for optical flow, called PWC-Net. PWC-Net has been designed according to simple and well-established principles: pyramidal processing, warping, and the use of a cost volume. Cast in a learnable feature pyramid,

An Information Flow Model for Conflict and Fission in Small Groups [PDF]
Journal of Anthropological Research, 1977 Data from a voluntary association are used to construct a new formal model for a traditional anthropological problem, fission in small groups. The process leading to fission is viewed as an unequal flow of sentiments and information across the ties in a ...

Parity flow as ${\mathbb Z}_2$-valued spectral flow [PDF]
, 2019 This note is about the topology of the path space of linear Fredholm operators on a real Hilbert space. Fitzpatrick and Pejsachowicz introduced the parity of such a path, based on the Leray-Schauder degree of a path of parametrices.

Attention Based Spatial-Temporal Graph Convolutional Networks for Traffic Flow Forecasting
AAAI Conference on Artificial Intelligence, 2019 Forecasting the traffic flows is a critical issue for researchers and practitioners in the field of transportation. However, it is very challenging since the traffic flows usually show high nonlinearities and complex patterns.

Stream lamination and rapid mixing in a microfluidic jet for X-ray spectroscopy studies
Flow, 2023 Microfluidic mixers offer new possibilities for the study of fast reaction kinetics down to the microsecond time scale, and methods such as soft X-ray absorption spectroscopy are powerful analysis techniques.
