Discussion of “Latent Variable Graphical Model Selection via Convex Optimization”
Latent Variable Graphical Model Selection Convex Optimization
2015/6/17
We wish to congratulate the authors for their innovative contribution, which is bound to inspire much further research. We find latent variable model selection to be a fantastic application of matrix ...
Multiple Space Debris Collecting Mission - Debris selection and Trajectory optimization
Multiple Space Debris Collecting Mission Trajectory optimization Systems and Control
2011/9/29
Abstract: A possible mean to stabilize the LEO debris population is to remove each year 5 heavy debris like spent satellites or launchers stages from that space region. This paper investigates the Del...

2010/12/28
One of the most interesting scienti c challenges nowadays deals with the analysis and the understanding of complex networks' dynamics. In particular,a major issue is the de nition of new frameworks fo...
Bandwidth selection in kernel density estimation: oracle inequalities and adaptive minimax optimality
density estimation kernel estimators Lp–risk oracle inequalities adaptive estimation
2010/11/30
We address the problem of density estimation with L p–loss by selection of kernel estimators. We develop a selection procedure and derive corresponiding L p–risk oracle inequalities. It is shown that ...
Energy-Efficient Relay Selection and Optimal Relay Location in Cooperative Cellular Networks with Asymmetric Traffic
energy-efficient relay selection cooperative communication optimal relay location asymmetric traffic
2010/11/26
Energy-efficient communication is an important requirement for mobile relay networks due to the limited battery power of user terminals. This paper considers energy-efficient relaying schemes through ...

relay selection link adaptation distributed beamforming signaling throughput
2010/11/26
Relay selection enhances the performance of the cooperative networks by selecting the links with higher capacity.Meanwhile link adaptation improves the spectral efficiency of wireless data-centric net...
Joint Uplink and Downlink Relay Selection in Cooperative Cellular Networks
relay selection cooperative networks energyefficient asymmetric traffic weighted energy consumption
2010/11/26
We consider relay selection technique in a cooperative cellular network where user terminals act as mobile relays to help the communications between base station (BS) and mobile station (MS).
Fixation in Evolutionary Games under Non-Vanishing Selection
Non-Vanishing Selection evolutionary game
2010/4/7
One of the most striking effect of fluctuations in evolutionary game theory is the possibility for mutants to fixate (take over) an entire population. Here, we formulate a WKB (Wentzel-Kramers-Brillou...
