Onset of lasing in small devices: the identification of the first threshold

no code implementations1 Mar 2018 Tao Wang, Gian Piero Puccioni, Gian Luca Lippi

We present a simple and flexible technique for identifying the onset of coherent emission in lasers, from the mesoscale to the nanoscale, which makes use of photon counting and a small amplitude modulation added to the pump.

A Multi-parent Memetic Algorithm for the Linear Ordering Problem

no code implementations18 May 2014 Tao Ye, Tao Wang, Zhipeng Lu, Jin-Kao Hao

In this paper, we present a multi-parent memetic algorithm (denoted by MPM) for solving the classic Linear Ordering Problem (LOP).

Modeling Attractiveness and Multiple Clicks in Sponsored Search Results

no code implementations1 Jan 2014 Dinesh Govindaraj, Tao Wang, S. V. N. Vishwanathan

Our model seamlessly incorporates the effect of externalities (quality of other search results displayed in response to a user query), user fatigue, as well as pre and post-click relevance of a sponsored search result.

Time-dependent Hierarchical Dirichlet Model for Timeline Generation

no code implementations8 Dec 2013 Rumeng Li, Tao Wang, Xun Wang

Existing approaches neglect such hierarchical topic structure involved in the news corpus in timeline generation.
