Qualitatively Incorrect Features in the TDDFT Spectrum of Thiophene-Based Compounds

Anne-Clémence Corminboeuf, Basile Curchod, Alberto Fabrizio, Antonio Prlj, Leonard Floryan

Ab initio molecular electronic structure computations of thiophene-based compounds constitute an active field of research prompted by the growing interest in low-cost materials for organic electronic devices. In particular, the modeling of electronically e ...

Multi-Commodity Network Flow for Tracking Multiple People

Pascal Fua, François Fleuret, Jérôme Berclaz, Horesh Beny Ben Shitrit

In this paper, we show that tracking multiple people whose paths may intersect can be formulated as a multi-commodity network flow problem. Our proposed framework is designed to exploit image appearance cues to prevent identity switches. Our method is effe ...

3D Turbulence Measurements Using Three Synchronous Wind Lidars: Validation against Sonic Anemometry

Fernando Porté Agel, Giacomo Valerio Iungo, Fernando Carbajo Fuertes

This paper presents a technique to measure the time series of the three components of the wind vector at a point in space from synchronous measurements of three scanning Doppler wind lidars. Knowing the position of each lidar on the ground and the orientat ...

Models of non-relativistic quantum gravity: the good, the bad and the healthy

Sergey Sibiryakov, Diego Blas Temino

Horava's proposal for non-relativistic quantum gravity introduces a preferred time foliation of space-time which violates the local Lorentz invariance. The foliation is encoded in a dynamical scalar field which we call 'khronon'. The dynamics of the khrono ...

Tracking Multiple People under Global Appearance Constraints

Pascal Fua, François Fleuret, Jérôme Berclaz, Horesh Beny Ben Shitrit

In this paper, we show that tracking multiple people whose paths may intersect can be formulated as a convex global optimization problem. Our proposed framework is designed to exploit image appearance cues to prevent identity switches. Our method is effect ...

Theoretical Model of Polymer Plasma Laser Ablation

Maria-Alexandra Paun

Polymer plasma laser ablation has been investigated theoretically. An elegant mathematical tool using the fractal structure of space-time was developed. The model was verified with good accuracy on the existing experimental results. ...

Investigations of time dependent flow phenomena in a turbine and a pump-turbine of Francis type : rotor-stator interactions and precessing vortex rope

Amirreza Zobeiri

The present work deals with time dependent phenomena, which develop in turbines and pump turbines of Francis type. These phenomena may cause serious damages to hydropower plant. The overall objective of this study is to bring a better understanding of two ...
