High performance monitoring and control of real-time environments over network is of importance to modern process control. The designed system focuses on meeting the special requirements of the control-level within factory communication systems to transmit real-time data via a switched Ethernet network. The architecture of the embedded-web based distributed(More)
In this paper, a face and eye tracking system for the detection of driver drowsiness is proposed. In order to meet real-time requirements, we use a probability measure based on information theory, which perform fast and robustly. The proposed system consists of two-steps: ROI extraction at the first frame, and eyes tracking at all frames. First, face is(More)
In this paper, we propose a new method called arbitrary shape region of interest (ROI) coding based on the integer-to-integer shape adaptive discrete wavelet transform (ISA-DWT). Firstly, the whole image is encoded to measure whether the reconstructed ROI PSNR is higher than the target. If it is true, it means that the estimated ROI PSNR is higher than the(More)
The electric properties (EPs) of biological tissue, i.e., the electric conductivity and permittivity, can provide important information in the diagnosis of various diseases. The EPs also play an important role in specific absorption rate calculation, a major concern in high-field MRI, as well as in nonmedical areas such as wireless telecommunications. The(More)
Holes in the skull and the scalp are associated with intracranial monitoring procedures. The purpose of the present study is to evaluate the effects of holes on extracranial electroencephalogram (EEG) and intracranial electrocorticogram (ECoG) recordings. The finite difference method (FDM) was used to model the head volume conductor with a hole of varying(More)
This paper describes the hardware configuration and software structure of an Internet-based control engineering laboratory. The laboratory provides a remote access to many experiment plants which all have distinguished features that render them worthwhile for experimentation for either control education or research. After logging on the laboratory to choose(More)
We propose a new algorithm to derive the anisotropic conductivity of the cerebral white matter (WM) from the diffusion tensor MRI (DT-MRI) data. The transportation processes for both water molecules and electrical charges are described through a common multicompartment model that consists of axons, glia, or the cerebrospinal fluid (CSF). The volume fraction(More)
A finite difference method (FDM) has been implemented to solve the electroencephalogram (EEG) forward problem. This method has been evaluated by means of computer simulations, by comparing with analytic solutions in a three-sphere concentric head model. The effects of dipole eccentricity, spacing of finite difference model and number of grid nodes on(More)
