Reshaping the Science of Reliability with the Entropy Function

open access: yesEntropy, 2015
The present paper revolves around two argument points. As first, we have observed a certain parallel between the reliability of systems and the progressive disorder of thermodynamical systems; and we import the notion of reversibility/irreversibility ...

Providing a decreasing congestion probability model for urban streets network [PDF]

open access: yesTransport, 2006
Urban streets classification systems are the basis for defining function and, in turn, the design criteria for the world’s streets networks. The traditional classification systems have been based on the mobility and access functions of roads for motor ...

Interictal Spike and Loss of Hippocampal Theta Rhythm Recorded by Deep Brain Electrodes during Epileptogenesis

open access: yesSensors, 2022
Epileptogenesis is the gradual dynamic process that progressively led to epilepsy, going through the latent stage to the chronic stage. During epileptogenesis, how the abnormal discharges make theta rhythm loss in the deep brain remains not clear.
