The International Thermonuclear Experimental Reactor (ITER) fusion project's council has put back for a year an announcement on its updated timeline for the project - and is proposing other changes in...
Relay Networks With Delays
Relay Networks Delays
2015/8/12
The paper investigates the effect of link delays on the capacity of relay networks. The relay-with-delay is defined as a relay channel with relay encoding delay of d 2 units, or equivalently, a delay ...
A Simple Condition for the Convexity of Optimal Control over Networks with Delays
Convexity Delays
2015/6/19
We consider the problem of multiple subsystems, each with its own controller, such that the dynamics of each subsystem may affect those of other subsystems with some propagation delays, and the contro...
Decentralized Control Subject to Communication and Propagation Delays
Propagation Delays Communication
2015/6/19
In this paper, we prove that a wide class of distributed control problems subject to communication and propagation delays are equivalent to convex optimization problems. The results hold in both conti...
Information State for Markov Decision Processes with Network Delays
Network Delays Decision Processes
2015/6/19
We consider a networked control system, where each subsystem evolves as a Markov decision process (MDP). Each subsystem is coupled to its neighbors via communication links over which the signals are d...
Optimal Control of Distributed Markov Decision Processes with Network Delays
Network Delays Decision Processes
2015/6/19
We consider the problem of finding an optimal feedback controller for a network of interconnected subsystems, each of which is a Markov decision process. Each subsystem is coupled to its neighbors via...
We consider a networked control system, where each subsystem evolves as a Markov decision process with some extra inputs from other systems. Each subsystem is coupled to its neighbors via communicatio...
MULTISTATION ESTIMATING OF GPS SIGNAL ATMOSPHERIC DELAYS BY UNDIFFERENCED OBSERVATIONS
GPS Real-time Algorithms Software Tracking
2015/5/29
Precise RTK positioning is usually performable only on short length bases, to limit distance correlated biases, as atmosphere and ephemerides. However, it is possible to recover some residual biases a...
14 YEARS OF GPS TROPOSPHERIC DELAYS IN THE FRENCH-ITALIAN BORDER REGION: A DATA BASE FOR METEOROLOGICAL AND CLIMATOLOGICAL ANALYSES
Climate Databases Geodesy Meteorology Monitoring International Networks GPS
2014/4/24
GPS data from 181 permanent stations extracted from different networks covering France and the Italian part of the Alps are used to
estimate a homogeneous set of tropospheric parameters over 14 year...
