In this study, a developed automatic sleep stage classification system with a portable EEG recording device, (Mindo-4s) is implemented by JAVA-based sleep graphical user interface (GUI) in android platform. First, the parameters of the developed sleep stage classification system, including extracting effective sleep features and a hierarchical classification structure consisting of preliminary wake detection rule, adaptive adjustment scheme, and support vector machine, were trained by our existing sleep database, which collected using polysomnogram (PSG), in MATLAB program. Finally, this classification system would be reedited by JAVA language, and the corresponding JAVA-based sleep GUI software was working in android platform and Mindo-4s. The connection between JAVA-based sleep GUI software and the portable Mindo-4s was through Bluetooth communication. The performance of this JAVA-based sleep GUI can reach 72.43% average accuracy comparing to the result from manual scoring. This JAVA-based sleep GUI can on-line display, record and analyze the forehead EEG signals simultaneously. After sleep, the user can received a complete sleep report, including sleep efficiency, sleep stage distribution, from JAVA-based sleep GUI. Thus, this system can provide a preliminary result in sleep quality estimation, and help the sleep doctor to decide someone needs to have a complete PSG testing in hospital. Using this system is more convenient for long-term and home-based daily caring than traditional PSG measurement. © Springer-Verlag Berlin Heidelberg 2013.

The use of discrete event simulation integrated with energy consumption computation is nowadays very useful for the efficient design of an industrial production plant. In this paper a serial manufacturing line made by four operating machines has been modelled by means of SIMIO discrete event simulator, focusing on the production line energy consumption computation. Each operating machine has been described according to three different aspects. Firstly the mechanical behaviour, that is guaranteed from the simulator modelling functionalities itself. Secondly the control functionalities that have been designed by means of Finite State Machines (FSMs), then translated into the C# programming language and finally integrated into the SIMIO platform. Finally the energy consumptions, that have been computed by modelling the energy states associated to the different operating machine working functions. In the end a simulation experiment has been run and the regarding results have been presented. The power absorbed and the energy consumed from the whole plant and from each single machine have been compared in order to allow the discussion about possible actions to be taken in order to respect the maximum amount of energy supplied to the plant, value that often represents a primary economic constraints for the industrial plant management. Main limitations coming from the proposed work regard the missing of plant power and energy measurement and the level of approximation used to model the different machines energy consumption.

In this work, SISO Quantitative Feedback Theory (QFT) technique is used to synthesize a regulatory feedback controller for a robust control of boiler drum-level considering boiler operation across multiple operating points. A simplified linear model is developed using a step test data generated from the boiler simulator based on the semi-distributed nonlinear model. Model parameter uncertainty is considered based on the model-parameter variations across linearized plant-set obtained across different operating point across transient operation. The feedback controller is designed to meet desired disturbance rejection specification. The design is verified through extensive simulations in time domains with several plants picked from the plant-set and simulation results are discussed. The performance of QFT controller is compared and found better against PI controller tuned for the same disturbance rejection specs.

Situation awareness(SA) continues to receive a considerable amount of attention from the ergonomics community. But, techniques to measure SA have normally used expert judgment or a self-rating method so far. One of the problems of these techniques is inconsistency of results. So, empirical and analytical studies on an objective and quantitative SA measurement methods have been carried out at Nuclear I&C and Information engineering Lab(NICIE Lab) in Korea Advanced institute of Science and Technology(KAIST). Empirical studies are based on physical and cognitive human behaviors, whereas analytical studies are mainly based on Bayesian inference. Eye movement signals and verbal protocol analysis were used for empirical approaches to obtain objective measures. FIR and SAE measures showed feasibility of an eye-tracking method for robust application. TSA score based on a verbal protocol analysis also showed its possibility of team SA(TSA) quantification. Bayesian inference was used for analytical approaches of SA quantification. The analytical quantification method was further expanded to consider some of the important human properties, and a SA modelling tool called ‘Co RSAGE, ver01" was developed.

A long distance measurement system using a stereo camera mounted on a rotation control device is proposed for automatic ship control, and the performance of the system is presented to verify the usefulness of it. As a solution to prevent ship operators from maritime accidents owing to their strain for a long period, the distance measurement system is often required to automatically control the posture or berthing of a ship. Here, we discuss the system structure suitable for used environment and its experimental results. From the experiment conducted to imagine the distance measurement necessary to altering the posture and translational motion between a ship and its facilities, the average error for the range of 20 to 100 m was less than 1 percent.

A method for detecting spikes and slow burst in photic evoked electroencephalogram (EEG) was proposed. The spikes were detected by combining methods of the morphological filter and the similarity coefficient in the time domain. The slow burst was detected by using pole of AR model (auto-regressive model) in the frequency domain. The proposed method was applied for the photic evoked EEG data containing spikes and slow burst, and brought satisfactory coincidence with the results interpreted by a qualified electroencephalographer. © 2012 IEEE.

The non-stationary signal features are averaged in correspondence with the length of analysis time, thus making it impossible to highlight the signal characteristics and caused the difficulties in identifying or diagnosing faults. In this paper, the wavelet order spectrum method using a combination of wavelet transform (WT) and speed frequency ordering. The feature order does not change with variations in speed, thus can effectively identify non-stationary faults in mechanical equipment. In addition, principal components analysis (PCA) is used to extract the main features of the wavelet order spectrum and reduce the volume of data. This is combined with self-organizing maps (SOM) to devise an artificial intelligence method for fault diagnosis in non-stationary states. © (2012) Trans Tech Publications.

作者： Hanchevici, Arian-Bogdan Guta, Sergiu-Adrian Faculty of Automatic Control and Computers Department of Automatic Control and System Engineering Politehnica University of Bucharest Romania INCDTP Division: Leather and Footwear Research Institute 93 Ion Minulescu Bucharest Romania

In this paper we propose a supervised multi-agent control strategy for leather manufacturing processes. In a tannery numerous processes are performed and in order to control them we use an agent for each process. Due to the control from distance, the systems are affected by varying communication delays which can affect the quality of the final product. The supervisor is used to adjust, by using the fuzzy logic, the command provided by each agent. Simulation results are presented. The results show performance improvement when our control strategy is used.

This paper presents a design procedure of the virtual test environment for fail-safe algorithm development of a motor control unit (MCU) in the electric or hybrid-electric vehicle, using a hardware-in-the-loop (HIL) simulator. Mathematical models of the vehicle, the battery, the permanent magnet synchronous motor (PMSM), and the inverter are developed based on the physical and engineering principles and programmed to be executed in real-time. The programmed models emulate the performance of each component and run in the HIL simulator. The signal interface between the HIL simulator and a MCU is also developed by designing appropriate wire harness and signal matching. Fault diagnosis of a MCU is conducted to show the feasibility of the virtual test environment. Several different failure modes of the MCU are implemented and tested by the HIL simulator to show the possibility of fault detection and fault diagnosis algorithms of the MCU in real-time.
