Safe reinforcement learning for multi-energy management systems with known constraint functions

open access: yesEnergy and AI, 2023
Reinforcement learning (RL) is a promising optimal control technique for multi-energy management systems. It does not require a model a priori - reducing the upfront and ongoing project-specific engineering effort and is capable of learning better ...

Hidden Node Detection between Observable Nodes Based on Bayesian Clustering

open access: yesEntropy, 2019
Structure learning is one of the main concerns in studies of Bayesian networks. In the present paper, we consider networks consisting of both observable and hidden nodes, and propose a method to investigate the existence of a hidden node between ...

Massive MIMO for Wireless Sensing with a Coherent Multiple Access Channel [PDF]

open access: yes, 2015
We consider the detection and estimation of a zero-mean Gaussian signal in a wireless sensor network with a coherent multiple access channel, when the fusion center (FC) is configured with a large number of antennas and the wireless channels between the ...

Log-biharmonicity and a Jensen formula in the space of quaternions [PDF]

open access: yes, 2018
Given a complex meromorphic function, it is well defined its Riesz measure in terms of the laplacian of the logarithm of its modulus. Moreover, related to this tool, it is possible to prove the celebrated Jensen formula. In the present paper, using among

Temperature, not LuxS, mediates AI-2 formation in hydrothermal habitats [PDF]

open access: yesFEMS Microbiology Ecology, 2009
Quorum sensing provides the basis for coordinating community-wide, microbial behaviors in many mesophilic bacteria. However, little attention has been directed toward the possibility that such phenomena occur in extremely thermal microbial environments.

Stability analysis of reinforced soil slopes based on observation of reinforcement-effected strip

open access: yesYantu gongcheng xuebao, 2017
In order to observe the effected strip of geogrid-reinforcement, a series of geogrid pull-out tests are conducted in a test box which has one Plexiglas wall, applied 4 different vertical pressures on each specimen prepared respectively with 6 granular ...

One-dimensional electroosmosis consolidation model considering variable saturation

open access: yesYantu gongcheng xuebao, 2017
The existing models for electroosmosis are based on the hypothesis of fully saturated soil regime. Variable saturation occurs in the soil regime, thus a new model is expected to improve the calculation accuracy.
