the study of the correlations that may exist between neural signals generated by different brain regions is a critical issue in understanding brain functions. there is a lack of an appropriate approach which is capable of (1) estimating the correlation between neural signals, and (2) adapting to the quickly increasing scales and sizes of neural signals. Wavelet coherence is an effective method for investigating the interaction dynamics between neuronal oscillations. Continuous wavelet transform (CWT) is suitable for analyzing neural signals which are non-stationary in nature. CWT forms the basis of wavelet coherence methods. However, the wavelet coherence method has been largely hampered by the high complexity of CWT. Aiming at this problem, this study proposed an improved wavelet coherence method withparallelized wavelet transform upon General-purpose computing on the graphic processing unit (GPGPU), namely, GPGPU-enabled wavelet coherence (GWC). the proposed method has been used to analyze 32-channel ERP recordings. the experimental results indicate that (1) the correlation between different neural signals can successfully indicate the different reactions of brain regions when people are watching videos and (2) GWC solves the performance bottleneck withthe conventional counterparts.

this paper presents a novel approach to the study of heterogeneous networks. NetBoxIT is a modular, and scalable testbed based on virtualized network emulators. these can be interconnected and run in parallel to reproduce complex networks scenarios within a shared, multi-core hardware platform. We examine the testbed performance with simple emulation trials (related to the reference Emergency network under study within the EU 7th FP project "A holistic approach towards the development of the first responder of the future"), to verify its realism in assessing multipart networks evaluations.
the ability to live migrate virtual machines (VMs) between physical servers without any perceivable service interruption is pivotal for building more energy efficient Cloud computing infrastructures in the future. Nev...

Constructing a scientific and effective bank risk forewarning model is an important measure to effectively guard against and defuse risks in commercial banks. this article constructs a bank risk forewarning model using BP neural network and principal component analysis method. Meanwhile, being aimed at that it takes a long time while processing the mass data to train the network, it also decomposes the algorithm for MapReduce, running in parallel to reduce the running time. the experiment result shows that the neural network model achieved higher accuracy of rate 88percents.
In a cloud computing environment, users prefer to migrate their locally processing workloads onto the cloud where more resources with better performance can be expected. ProtoGENI [1] and PlanetLab [17] have further i...

In this paper, we describe the implementation of a real time visualization and feedback system for Wireless Sensor network algorithms. the system is based on a fixed hardware testbed, which is deployed on a vertical flat surface and a feedback loop system that takes information about the current state of the network and projects this state, in a visual way, on the surface itself using a video projector. the protocol used is open and simple to use, and can be easily adapted for different hardware configurations. We call our system Irida.
