Rössler and Chen systems with time delay are shown to be hyperchaotic, which exhibits a more complex dynamics, including multiple positive Lyapunov exponents and infinite dimension. The hyperchaos has better application potential where hyperchaos synchronization is concerned. Univariate impulse control requires smaller perturbation to the response system, thus promising better performance. However, synchronization of two hyperchaotic systems using this control method is a challenging task due to the difficulty to guarantee synchronization stability using a minimum number of manipulated variables. In this paper, a univariate impulse control method is proposed for the synchronization of two hyperchaotic dynamics generated by time delay. A theorem is developed and proved to provide the sufficient conditions for the synchronization of time delay systems using the univariate impulse control. The upper bound of the impulse interval is proved to guarantee the asymptotic synchronization. Simulation and circuit experiment show the correctness of the analysis and the feasibility of the proposed method.

Secure communication using hyperchaos has a better potential performance, but hyperchaotic impulse circuits synchronization is a challenging task. In this paper, an impulse control method is proposed for the synchronization of two hyperchaotic Chen circuits. The sufficient conditions for the synchronization of hyperchaotic systems using the impulse control are given. The upper bound of the impulse interval is derived to assure the synchronization error system to be asymptotically stable. Simulation and circuit experiment show the correctness of the analysis and feasibility of the proposed method. Copyright © 2019, The Authors. All rights reserved.

The paper first makes an overview on the genetic properties of the odd integers by summarizing tens of theorems that have been proved in literatures, and then presents several new theorems related with the genetic properties and with the divisor's distribution of a composite odd integer. Based on the theorems, the paper also proposes a guideline of designing parallel algorithm to factorize an odd integer. Numerical experiments show the genetic property is helpful for solving the hard problem of integer factorization. © 2018 IEEE.

Abstract-Temperature sensing characteristics of surface acoustic wave Brillouin scattering in 1-1.3 $\mu\mathrm{m}$ diameter optical microfibers are simulated by using the elastodynamic equation including the electrostrictive stress. A multi-peak Brillouin gain spectrum with rather high scattering efficiency is observed. The highest temperature sensitivity of the surface acoustic mode is 0.568 MHz/°C. Meanwhile, the temperature sensitivity of the surface acoustic mode is less affected by fiber diameter changes, ranging from 0.05 to 0.25 MHz/°C/$\mu\mathrm{m}$. It can be found that using SAW BS for temperature sensing would put less stress on manufacturing constraints for optical microfibers. Moreover, the results provide guidance for the further improving the performance of temperature sensing in the microelectronics field.

Valuated binary tree is emerging its magical characteristics in study of integers. As the father tree of all valuated binary subtrees, T3 tree plays a very important role in studying the odd integers for its owning both the common properties of a general valuated binary tree and its own traits of covering all the odd integers bigger than 1. The article investigates the properties of the T3 tree as well as the multiplications on the tree. It exhibits the distribution of a node's multiples, the distribution of the product of two nodes and the distribution of the square of a node. Some other contents such as fundamental properties of the T3 tree and path connecting a product to its divisor-nodes are also investigated with detail mathematical proofs. The theorems and corollaries proved in the article lay a foundation for future work.

Basically, wind turbines capture wind power and convert it into electricity. Conventional operation using a single set of rotating blades of the wind turbine, thus it will limit the rotation of the generator's stator. This condition will cause the generated output voltage is limited. The purpose of this project is to design and develop a double rotational generator with a double rotational vertical axis wind turbine that has the ability to produce double output voltages and functional in both high and low wind speed condition. Therefore, a certain shape and size of the blade are divided efficiently designed for this project. The output voltages generated by cutting the magnetic flux generator which combines the use of permanent magnets and a set of winding. The project performance was analyzed based on the effect of wind speed on the output voltages that induced by cutting magnetic flux.

This paper presents a linear time invariant model identification for beetle mimicking flapping wing micro air vehicle (FWMAV) in hovering mode. The identification is facilitated by assuming the wings of the beetle rectangular in shape and the body is considered cylindrical. The main thrust is provided by flapping the wings of the FWMAV whereas the trailing-edges-change mechanism was kept off. The measurable aerodynamic forces and moment's measured data are utilized in the states' reconstruction. The state reconstruction was carried out via the discrete time integration of linear and angular acceleration. Having reconstructed the states, the standard least mean square estimation (LMSE) based estimation approach is used to estimate the system's stability and control derivatives. The results of the estimation are validated with the experimental data, and show the success of the estimation approach. © 2016 IEEE.

Vehicle detection in real-time from rear-side of a host vehicle is one of important problems in Lane Change Assistance. In this paper, we propose a vision system for real-time vehicle and lane detection and tracking using two cameras, which are equipped under the wing mirror both left and right side. From the input images, EDLines algorithm is used for line segment detection in real-time. According to the achieved data, lane detection is developed by analyzing angles of the line segments, and area between two lanes on the same side of vehicle is defined. In the vehicle detection, based on the brightness and darkness between vehicle and road, vehicle is detected in real-time using the simple algorithm. Finally, kalman filter is used in vehicle tracking for vehicle information such as distance or speed.

In this paper, the state feedback control design problem for stabilizing a two-wheeled wheelchair in balancing mode is considered. The system is modeled as double-inverted pendulum on two wheels. The calculation of state feedback control gains is conventionally handled by LQR method via Riccati equation. Unfortunately, the method still possesses trial and error approach when choosing some parameters, in particular tuning the elements of Q and R weighting matrices. Therefore, an intelligent numerical method to resolve this problem is proposed by adopting PSO algorithm. The simulation work is carried out to evaluate the effectiveness of the proposed method. The result shows that the numerical method reduces tuning time and improves the performance of the system.

In this paper, a nonlinear adaptive control of a 3D overhead crane is investigated. A dynamic model of the overhead crane is developed, where the crane system is assumed as a lumped mass model. Under the mutual effects of the sway motions of the payload and the hoisting motion, the nonlinear behavior of the crane system is considered. A nonlinear control model-based scheme is designed to achieve the three objectives: (i) drive the crane system to the desired positions, (ii) suppresses the vibrations of the payload, and (iii) velocity tracking of hoisting motion. The nonlinear control scheme employs adaptation laws that estimate unknown system parameters, friction forces and the mass of the payload. The estimated values are used to compute control forces applied to the trolley of the crane. The asymptotic stability of the crane system is investigated by using the Lyapunov method. The effectiveness of the proposed control scheme is verified by numerical simulation results. © 2015 Institute of Control, Robotics and systems - ICROS.
