Numerous works have been dedicated to the development of signal processing methods aimed at measuring the degree of association between EEG signals. This interdependency parameter is often used to characterize the functional coupling between different brain structures or regions during either normal or pathological processes. In this paper we focus on the(More)
In this paper an application of intelligent systems for optical networks design is proposed. The Routing and Wavelength Assignment (RWA) in Dense-Wavelength-Division-Multiplexing (DWDM) optical networks under dynamic traffic patterns is addressed. We mainly focus on how to apply Artificial Bee Colony (ABC) algorithm to solve dynamic RWA problem by(More)
By assuming the brain as a multi-stable system, different scenarios have been introduced for transition from normal to epileptic state. But, the path through which this transition occurs is under debate. In this paper a stochastic model for seizure genesis is presented that is consistent with all scenarios: a two-level spontaneous seizure generation model(More)
In order to predict epileptic seizures many precursory features, extracted from the EEG signals, have been introduced. Before checking out the performance of features in detection of pre-seizure state, it is required to see whether these features are accurately extracted. Evaluation of feature estimation methods has been less considered, mainly due to the(More)
Capability and complexity of applied programs are growing rapidly. These factors cause to increase volume and complexity of connection patterns in-chip. An appropriate connection infrastructure in-chip, called Network on Chip(NOC), is required to face efficiently this complexity. For measuring the performance of this type of network, criteria such as(More)
In this paper, a model-based approach is presented to quantify the effective synchrony between hippocampal areas from depth-EEG signals. This approach is based on the parameter identification procedure of a realistic Multi-Source/Multi-Channel (MSMC) hippocampal model that simulates the function of different areas of hippocampus. In the model it is supposed(More)
