Pneumatic Muscle (PM) has the advantages of cheapness, light weight, compliance, safe and high power/weight. It is suitable for rehabilitation engineering. To minimize the number of PM for driving a single joint of rehabilitation, a new PM-TS actuator comprising a PM and a Torsion Spring (TS) is proposed. Unlike the traditional agonist/antagonist PM actuator, the PM is arranged in appropriate place as agonist and the torsion spring provides opposing torque as antagonist in the proposed actuator. The dynamic model of a 1-DOF (Degree of Freedom) rehabilitation robotic arm is derived considering the PM-TS actuator. To realize high accurate trajectory tracking control of the robotic arm, an Artificial Bee Colony (ABC) algorithm based Auto-Disturbance Rejection control (ADRC) is proposed, where ABC is employed to optimize the control parameters of ADRC. Simulation results demonstrate the validity of PM-TS actuator, and verify that the ABC based ADRC has satisfactory performance. © 2012 Huazhong Univ of Sci & Tec.

Micromanipulation robot is a system which often does some precise manipulations in micro scale space, such as centimeter or millimeter level space, in which micro visual servo system plays a very important role. In visual servo system, it's difficult to give consideration to two or more things such as location accuracy and real-time property at the same time. In this paper, we introduced a novel approach which suited our system very well and could meet both of the above requirements. It was called ORB, a novel feature extracting method which outperformed many current excellent methods such as SIFT and SURF. © 2012 Huazhong Univ of Sci & Tec.

P systems are distributed parallel computing models in the area of membrane computing, which are inspired by the structure and the functioning of living cells, as well as the organization of cells in tissues, organs, and other higher order structures. P systems with proteins on membranes are a class of P systems, which have proved to be very efficient computing devices. Specifically, it was known that the Quantified satisfiability problem (QSAT) of a Boolean formula can be solved by a semi-uniform family of P systems with proteins on membranes and with membrane division. However, it remains open whether a uniform families of P systems with proteins on membranes can solve in polynomial time exactly the class of problems PSPACE. In this work, we present a uniform solution to QSAT problem by P systems with proteins on membranes in a linear time with respect to both the number $n$ of Boolean variables and the number $m$ of clauses of the instance, which answers the above open problem.

A Dynamic Time Warping (DTW) based voice recognition approach and its template training problem are discussed in this paper. In order to achieve better recognition accuracies, we proposed two kinds of incremental feedback learning methods for DTW-based voice recognition, including the variable gain coefficient (VGC) based method and the time warping average (TWA) based method. Compared with the non-feedback recognition system, the proposed methods are easy to implement and more robust to noise. A number of comparison experiments are performed to demonstrate the effectiveness of the proposed method. It is also shown that the VGC-based method, whose implementation is easy, achieves significantly better performance than conventional batch template training method without feedback learning. © 2012 Huazhong Univ of Sci & Tec.

With the development of society and progress of technology, people are concerned with their health more and more. Currently there are increasing number of handicapped people, which brings tremendous burden to the society and their families. For handicapped people, bathing is a big challenge because of disabilities and some dangers such as falling down or drowning which will cause severe consequence if not be dealt with in time. To alleviate the burden of society and their families as well as guarantee their safety during bathing, we propose an integrated wearable bath safety monitoring system. This system can detect both fall and drowning emergencies during bathing in real-time and alarm to remote monitoring center for help. The effectiveness of the propose safety monitoring system is confirmed by experiments. © 2012 Huazhong Univ of Sci & Tec.

This paper describes a wearable stimulating system to investigate the effects of epidural spinal cord stimulation (ESCS) on the improvement of locomotion performance in rats with incomplete spinal cord injury (ISCI). The preliminary experiment was conducted in a 240 g Sprague Dawley rat. With different spinal cord stimulation intensities, the EMG signal was recorded from hindlimb using needle recording electrode in rats under anesthesia. It is shown that the proposed stimulating system is available for the chronic stimulation in the ISCI rodent model to investigate the mechanism of ESCS on the improvement of locomotion performance for ISCI patients. © 2011 IEEE.

It is difficult to rescue people from outside, and emergency evacuation is still a main measure to decrease casualties in high-rise building fires. To improve evacuation efficiency, a valid and easily manipulated grouping evacuation strategy is proposed. Occupants escape in groups according to the shortest evacuation route is determined by graph theory. In order to evaluate and find the optimal grouping, computational experiments are performed to design and simulate the evacuation processes. A case study shown the application in detail and quantitative research conclusions is obtained. The thoughts and approaches of this study can be used to guide actual high-rise building evacuation processes in future.

DNA tile self-assembly is a promising paradigm for nanotechnology. Recently, many researches show that computation by DNA tile self-assembly maybe scalable. In this paper, we propose the algorithm for elliptic curve Diffie-Hellman key exchange based on DNA tile self-assembly. First we give the DNA tile self-assembly model to compute the scalar multiplication, then we can successfully implement the Diffie-Hellman key exchange over elliptic curve by extracting the result strand of the scalar multiplication.

This paper proposes a fog weather data augmentation method for the unmanned surface vessels (USVs) via improved Generative Adversarial Network(GAN) model. First, a generator scheme for GAN is proposed with the guided generation of the atmospheric scattering model in this paper. A Laplacian Pyramid Based Depth Residuals model is added to the generator which reduces the difficulty of generating fog images caused by the degradation of water surface image and improves the quality of generated images. Finally, fog images are generated from sunny weather images collected with HUST-12C by LPBDR-GAN model and experiments show that generated images are very close to real fog images. © 2023 Technical Committee on control Theory, Chinese Association of Automation.
