The purpose of this paper is to analyze apparent age feature based on age perception. In order to construct the apparent age database, age estimation experiment is performed to the HOIP facial database by 60 subjects. We defined 46 age features which contribute to the age perception from facial image. This process is performed based on research on age acknowledgment in field psychology and technological conventional method about real-age estimation from facial image. The apparent age feature used potentially when human performs age estimation is decided from 46 defined features by using the AIC and the multiple linear regression analysis. By using the proposed method, facial features that influenced on the apparent age in each gender was confirmed.

Automatic electroencephalogram (EEG) interpretation based on referential derivation is easily interfered by ear lobe activation. In order to improve the quantitative EEG interpretation of dominant rhythm, bipolar derivation was proposed in this study. Coherence and phase obtained from cross spectrum analysis were used to determine the focus of dominant rhythm. Existence, peak frequency, amplitude and asymmetry of dominant rhythm were interpreted within the frequency band from 4 to 13Hz. The automatic interpretation of dominant rhythm based on bipolar derivation was compared with the visual inspection of electroencephalographer (EEGer) and showed good consistence.

EEG is represented to referential derivation with ear lobe reference and bipolar derivations for quantitative interpretation. When the ear lobe was activated, referential derivation with ear lobe reference was contaminated by ear lobe artifacts. In this study, the focus and extension of EEG components were estimated based on the cross spectrum of bipolar derivation. A referential derivation was constructed by choosing the electrodes out of the focus and extension area to obtain the distribution of EEG components. The constructed referential derivation can avoid the artifacts of ear lobe activation for quantitative EEG interpretation.

Quantitative analysis and detection of abnormalities for electroencephalogram (EEG) recordings during evoked activities are essential for clinical diagnosis on neurological disorders. However, the process of interpreting EEG is time consuming and requires experienced electroencephalographers (EEGers). In this study, a method of automatic EEG interpretation during hyperventilation was proposed. The purpose is to provide a quantitative interpretation of EEG which is able to conform to EEGers' visual inspection. The final integrated results of automatic interpretation were compared with EEGers' evaluation, and showed high consistence.

IEEE India Conference (INDICON)

作者： Zeynab Naseri Mohammad Haeri Advanced Control System Lab Electrical Engineering Department Sharif University of Technology Tehran Iran

In this paper, the problem of resource allocation at an Ad hoc network with nodes not using any infrastructure to cooperate with each other is considered. By using a simple interference model in wireless links, the convergence and stability of a fair resource allocation scheme in the absence of delay is investigated. Also, the local stability of the scheme in the presence of upper-bounded delay is verified. Simulations results illustrate the convergence and fairness of this scheme considering different initial states for different sources. The performance of the scheme in the presence of different disturbances for each flow in transient and steady state along with its local stability in the presence of upper-bounded delay is also examined.

International Conference on control, Automation and systems ( ICCAS)

作者： Narges Nazari Mohammad Haeri Mohammad Saleh Tavazoei Advanced Control System Lab Department of Electrical Engineering Sharif University of Technology Tehran Iran

This paper deals with the identification of fractional order systems via orthogonal rational functions. These functions have widely been used in system identification of classical integer order systems. It has been shown that due to some properties such as the presence of non-exponentional aperiodic multimodes in the fractional order systems, it is much better to use fractional orthogonal rational functions in approximation of these systems. One problem which arises in this area is the estimation of fractional order of these orthogonal rational functions. In the existing methods, these parameters have been found by trial and error which requires a large amount of calculations. To reduce the computational effort, a new strategy is suggested in the present work to estimate the fractional order. The proposed strategy is constructed based on pre-processing the step response of the system in hand.

This paper discussed a nonlinear trajectory tracking problem for stratospheric airship platform and a novel approach of the nonlinear control scheme is applied. Target airship model is the 200 m stratospheric airship platform capable of flying upto 20 km altitude. Full 6-DOF nonlinear dynamics of unmanned airship are defined according to the target airshippsilas configuration including the moving wind field. Based on this airship model, a backstepping design formulation for the trajectory tracking control is described. The tracking control strategy of vectorial backstepping is applied to derive the tracking control law and global asymptotically stability is proved by Lyapunov stability analysis. Finally, numerical simulations have been carried out to assess the performance of the proposed tracking controller.

Humanitarian demining: Reality and the challenge of technology - The state of the arts

International Journal of advanced Robotic systems 2007年第2期4卷 151-172页

作者： Habib, Maki K. Department of Advanced System Control Engineering Graduate School Sciences and Engineering Saga University Japan

In the context of humanitarian demining it is essential to have a reliable and accurate sensor or an integration of heterogeneous/homogeneous sensors with efficient and reliable data fusion and processing techniques. In addition, it is necessary to overcome the constrain on the resources to speed up the demining process in terms of time, cost, and safety enhancement of personnel and operation. A portable handheld mine detection approach to sensor movement is slow and hazardous for individual deminers. Armored vehicles may not thoroughly protect the occupants and may be of only limited usefulness in off-road operations. Robotized solutions with effective sensing capabilities properly sized with suitable modularized mechanized structure and well adapted to local conditions of minefields can greatly improve the safety of personnel as well as work efficiency and flexibility. Such intelligent and flexible machines can speed the clearance and perform verifying processes when used in combination with handheld mine detection tools. Furthermore, the use of many robots working and coordinating their movement will improve the productivity of the overall mine detection process through the use of team cooperation and coordination. This paper evaluates the available mine clearance technologies and disscusses their development efforts and limitations to automate tasks related to demining *** addition, it introduces technical features and design capabilities of a mobile platform needed to accelerate the demining process and achieve safety with cost effective measures.

IEEJ Transactions on Sensors and Micromachines 2007年第5期127卷 290-296+4页

A sphere-shape angular position sensor for measurement inclination angle and inclined direction simultaneously based on multifunctional sensing approach is proposed, which is characterized in the following respects, such as the measurement of two angles, a full-range measurement, and has a compact and single structure. Three coils wound on the surface of a plastic ball with half sphere compose three inductances as the outputs of sensor. Magnetic fluid is selected as the inertial element attributed to its liquidity and electromagnetism character. We herein discuss the working principle of the sensor, its detailed configuration and its geometrical analysis. A prototype is built, the measuring results of which examines the feasibility of proposed method. Two angular parameters are successfully evaluated by using 2-D cubic spline interpolation.
