Since the liver perfusion computed tomography (CT) imaging was described. It has been generally used with the development of imaging techiques and poes-processing software. Just like the Magnetic Resonance (MR) Imaging has become the research focus of liver perfusion. In this paper we describe an automated method to detect the hepatopathy based on MR perfusion

Coherent detection can detect all the information encoded in the optical signal, which allows information symbols to be encoded in all the degrees of freedom available in a fiber, leading to improved power and spectral efficiency. Because of the business requirements of high-definition television and video conferencing, the capacity of network grows rapidly recently, which

Differential evolution of differential evolution algorithm is an emerging technology. It has less parameter settings, high efficiency of search, and lower complexity et al. At present, it has been successfully applied to robots, communications, neutral network training and other fields. Blind detection technology is firstly studied intensively 30 years ago. In this technology, the transmitted

Psychiatric disorders have become a serious public health and social problem, while there is still few quantitative criteria to diagnose these diseases well. One of the effective approaches to detect and diagnose neurological disorders is to use Deep Transcranial Magnetic Stimulation (DTMS) as the input to arouse brain specificity, and the corresponding EEG signal as

The adaptive filter can adjust their own parameters by iterative process using the adaptive filtering algorithm, when the statistical properties of the input signal is unknown or changes. Adaptive filter has been widely used in channel estimation, echo cancellation, noise cancellation, image restoration field and so on. Since the ability of handling digital signals, it

There are many complex systems in nature, the sturctures of their components may be quite simple, however, they can display very rich and complex global behaviors since there are local interactions among the components.Cellular automata are ideal mathematical models in studying complex systems. Cellular automata can be seen as discrete dynamical systems. The time, space
