This paper describes an unconstrained measurement system for scratching motion. We have proposed an unconstrained bed monitoring system by piezoceramic sensors that could detect heartbeat respiration and body movement. The system could measure the bed vibrations due to the motion of the person on the bed. In this paper, we apply this unconstrained bed sensing method to the system for detecting scratching motion. The proposed sensors are placed under the bed feet. When the subject is lying on the bed, the output signals from the sensors are proportional to the magnitude of the vibration due to the body movement of the subject. Hence, it is possible to detect the subject's scratching motion from the output signals. Furthermore, also with output signals from the three ceramic sensors, the proposed system can detect the direction of the body movement, which enables us to estimate the scratched area. We evaluated three scratching motions using the proposed system in the validity experiment as follows: Case 1 is the subject's scratching the right cheek with right hand;Case 2 is the subject's scratching the back after turning over, and;Case 3 is the subject's scratching the shin with another foot. As the results of the experiment, we identified the scratching signals that enable the determination when the scratching occurred. Furthermore, the difference among the amplitudes of the output signals enabled us to estimate where the subject scratched.

Three-dimensional dynamic modeling and numerical simulation of manipulating deformable linear objects (DLOs) such as hoses, wire and cables are studied in this paper. Several coordinate systems are introduced first to describe the deformation of DLOs. The dynamic three-dimensional deformation of an inextensible linear object is formulated using finite element method (FEM) and lagrange motion equations. The proposed method provides more efficient simulation of dynamic manipulating DLOs with faster computation speed. Two simulation examples are illustrated to confirm the effectiveness of our methods. One is a comparison simulation study and the other shows the three-dimensional dynamic character of the DLO. © 2011 Chinese Assoc of Automati.

Researches on robotic manipulation mainly focus on rigid objects. Whereas, manipulating deformable linear objects (DLOs) such as hoses, wires, cables is common in daily life and many domains such as manufacture, medical surgery and so on. The DLOs are more challengeable to handle, as the uncertainty results from oscillation at the end of DLOs may cause failure in the operation. During manipulating DLOs, especially moving them rapidly, the dynamic characteristics can not be neglected. In this paper, based on the dynamic model of DLOs, we illustrate a skill-based manipulating strategy for eliminating the vibration at the end of DLOs. The method is position-based and inspired from human manipulation skills. From our life experience, when people manipulate DLOs by hand, the oscillation will be significantly reduced if we suddenly lift it up with a certain acceleration. Based on the idea and dynamic model of DLOs, the control strategy by using fuzzy and PI controller is illustrated. The effectiveness of the proposed strategy is confirmed by numerical simulation results. The simulation results show that the proposed method can damp the vibration effectively. © 2011 IEEE.

The carrier recovery is one key technique in the demodulation of high order quadrature amplitude modulation (QAM) signals. A carrier recovery algorithm which switches between multi-threshold polarity decision mode and decision directed mode according to the standard deviation of the frequency of numerically controlled oscillator (NCO) is proposed. The proposed algorithm can detect a proper time for the mode switch to yield lower steady state error. The simulation results demonstrate the effectiveness of the proposed algorithm in improving the performance of blind carrier recovery.

Parametric ship roll resonance is a phenomenon where a ship can rapidly develop high roll motion while sailing in longitudinal waves. This effect can be described mathematically by periodic changes of the parameters of the equations of motion, which lead to a bifurcation. In this paper, the control design of an active u-tank stabilizer is carried out using Lyapunov theory. A nonlinear backstepping controller is developed to provide global exponential stability of roll. An extension of commonly used u-tank models is presented to account for large roll angles, and the control design is tested via simulation on a high-fidelity model of a vessel under parametric roll resonance. © 2009 EUCA.

Minimum changes bandwidth allocation (MCBA) is an optimal video transmission scheme resulting in the minimum number of rate changes with the minimum peak rate, which can reduce renegotiation frequency in statistical multiplexing service. The existing MCBA algorithm with searching frontiers, however, has a high computational complexity, which depressed the applicability of MCBA. In this paper, we design a fast algorithm of MCBA that examines for the bounded point based on the convex envelopes of the overflow and underflow curve. As a result, our algorithm can work out an MCBA scheme in a shorter time because we can find the bounded point with a linear complexity, and calculate each transmission rate within several iterations. The simulation using real video traces confirmed the philosophy and efficiency of our algorithm.

In a measurement system, new representation methods are necessary to maintain the uncertainty and to supply more powerful ability for reasoning and transformation between numerical system and symbolic system. A grey measurement system is discussed from the point of view of intelligent sensors and incomplete information processing compared with a numerical and symbolized measurement system. The methods of grey representation and information processing are proposed for data collection and reasoning. As a case study, multi-ultrasonic sensor systems are demonstrated to verify the effectiveness of the proposed methods.

A service exposure test of advanced austenitic alloys was performed at Eddystone Power Station Unit 1. The alloys tested were TP347HFG;SUPER304H and HR3C as well as 17-14CuMo as a reference material. They were installed in the final super-heater section in 1991 and were removed in 2004. The service exposure duration is 75,075 h with the steam temperature and pressure estimated 615 degrees C and 35 MPa, respectively. Post exposure examination has proved no marked hot-corrosion and steam oxidation have occurred for the TP347HFG SUPER304H and HR3C specimens, while severe hot-corrosion and exfoliation of steam-oxide films was pronounced in 17-14CuMo specimens. It is also found that HR3C exhibits the highest tensile strength with a lowest ductility and TP347HFG does vice versa, while the strength of SUPER304H is equivalent to that of 17-14CuMo with much better ductility. Short-term creep rupture strengths of these alloys have been reduced to some extent after the long-term service exposure and a longer-term creep rupture testing has been in progress. Microstructural evolution of the TP347HFG, SUPER304H and HR3C as well as 17-14CuMo during the long-term service exposure have been analyzed using a detailed TEM examination and the chemical analysis of extraction residue of the exposed specimens.
