Geometrically-exact time-integration mesh-free schemes for advection-diffusion problems derived from optimal transportation theory and their connection with particle methods [PDF]

, 2017
We develop an Optimal Transportation Meshfree (OTM) particle method for advection-diffusion in which the concentration or density of the diffusive species is approximated by Dirac measures.

FollowMe: Efficient Online Min-Cost Flow Tracking with Bounded Memory and Computation [PDF]

, 2014
One of the most popular approaches to multi-target tracking is tracking-by-detection. Current min-cost flow algorithms which solve the data association problem optimally have three main drawbacks: they are computationally expensive, they assume that the ...

The Deflection of the Two Interacting Coronal Mass Ejections of 2010 May 23-24 as Revealed by Combined In situ Measurements and Heliospheric Imaging [PDF]

, 2012
In 2010 May 23-24, SDO observed the launch of two successive coronal mass ejections (CMEs), which were subsequently tracked by the SECCHI suite onboard STEREO.

A Unified Successive Pseudo-Convex Approximation Framework [PDF]

, 2016
In this paper, we propose a successive pseudo-convex approximation algorithm to efficiently compute stationary points for a large class of possibly nonconvex optimization problems.

Performance Modelling and Optimisation of Multi-hop Networks [PDF]

, 2012
A major challenge in the design of large-scale networks is to predict and optimise the total time and energy consumption required to deliver a packet from a source node to a destination node.

Weak-inertial flow between two rough surfaces [PDF]

, 2005
“Oseen–Poiseuille” equations are developed from an asymptotic formulation of the three-dimensional Navier–Stokes equations in order to study the influence of weak inertia on flows between rough surfaces.

Phase Structure and Compactness [PDF]

, 2010
In order to study the influence of compactness on low-energy properties, we compare the phase structures of the compact and non-compact two-dimensional multi-frequency sine-Gordon models.

Study of the collapse of granular columns using DEM numerical simulation

, 2005
Numerical simulations of the collapse and spreading of granular columns onto an horizontal plane using the Contact Dynamics method are presented. The final shape of the deposit seems to depend only on the aspect ratio $a$ of the columns; these results ...

Study on the peak shaving operation of cascade hydropower stations based on the plant-wide optimal curve

International Journal of Electrical Power & Energy Systems
A large number of renewable energy sources (RESs), such as wind and photovoltaics (PV), have increased the importance of hydropower stations with regulating capacity in peak shaving operation.

Numerical Computation of the Stable and Unstable Manifolds of Invariant Tori

, 2005
We develop an iterative technique for computing the unstable and stable eigenfunctions of the invariant tori of diffeomorphisms. Using the approach of Jorba, the linearized equations are rewritten as a generalized eigenvalue problem.
