To improve capacity and reduce interference, directional antennas are being become more and more important in ad hoc networks. A new MAC Protocol is proposed in this paper, termed dynamic TDMA protocol using directional antennas (NDTDD). The NDTDD dynamically allocates time slots for each beam of every node without center coordinator. The time frame is composed of three sub-frames, separately called admission, assignment and reservation sub-frames. The NDTDD takes full advantage of the characters of directional antennas. A node can transmit packets in different beams simultaneously. Each beam of new node can achieve high successful possibility entering the network in admission sub-frame. Coherence of available transmitting reservation slots set and receiving reservation slots set of the whole network is maintained by using only two-hop topology beam information. The reservation mechanism ensures that all beams get reservation slots fairly according to their traffic. The high spatial reuse ratio achieved by directional antennas makes the NDTDD achieve high time reuse ratio for ad hoc networks. Analysis and simulation results are presented to verify how this new protocol performs.

In this work, a high-precision infrared pulse laser ranging system based on FPGA and microcontroller Atmel16 is proposed for active vehicle anti-collision application, and the key technologies of this system including optical device, laser receiver component, and time-of-flight stretching component are studied deeply based on the principle of the pulse laser time-of-flight measurement. The light energy transmission is analyzed in detail to choose the proper transmitted and receiver laser diode. Specially, the method of the time stretching based on the charge and discharge of the high-precision capacitor using the constant-current sources is adopted to realize the measurement of time-off-light. The practical running of system prototype and test results show that the precision is ±0.1m, the repetition rate is 1 kHz, and the distance measurement range is up to 60 m from 1.5 m. So, this system can accurately detect the distance between the cars, and can efficiently avoid traffic accident, therefore, this system has greatly practical and economic value.

Grid calibration of the visual system introduces the rotating linear deformation. Just to compensate actual error with the error obtained from the visual system would result in lower accuracy for equipments. This paper would establish the mathematical transformation model between image coordinate system and world coordinate system. Test results reveal that this optimal compensation effectively improve the compensating accuracy on the whole working plane.

Filters are fundamental components widely used in Electric Information and Control Engineering. Filters based on rectangular waveguide have good performance with low loss, high operation frequencies and high power. But the design and optimizing is a rather complex job. In this paper, a neural network is introduced to optimize two parameters in a waveguide band-pass filter. The result shows that after training, the neural network can predict the S parameter well and make the process of optimizing easier.

The problem of H∞-control based on the dynamic output feedback for fuzzy descriptor system was studied. With a equivalent system constructed, the analysis of H∞-control for fuzzy descriptor system is converted to the analysis of H∞-control for common descriptor system. When the premise variables is unmeasurable, A new method for linear H∞-controller design of fuzzy descriptor system is given which avoid analyzing the subsystems of fuzzy descriptor system.

The theories of concept lattice expansion and recovery were presented in this paper. Firstly, a formal context can be reduced from the viewpoint of objects or attributes by inclusion reduction, and its corresponding concept lattice can be constructed. And then, the concept lattice can be expanded dynamically according to the need, thus, the concept lattice of original formal context can be recovered eventually. Finally, the paper shows that the concept lattice of the original formal context and that of the reduced formal context are monomorphic.

A switching control law is proposed to control the non-symmetrical underactuated surface vessel with non-integrable second-order nonholonomic constraints. First, global invertible transformations are used to transform the kinematics and dynamics of the vessel into two subsystems. Then, a Lyapunov-like function is used to constructed an invariant set based on which the switching control law is designed. This control law guarantees global exponential convergence rates and global asymptotical stability, that is, the global K-exponential stability. The simulation results verifies the effectiveness.

The force due to electromagnetic pick-up can affect the performance of small pipeline turbine flow sensor. Based on electric eddy current, a new pick-up was designed for eliminating the effect of reluctance torque in traditional pick-up. The range ability of DN4mm, DN6mm and DN10mm turbine flow sensor were expanded to 10∶1. The reliability of nonlinearity correction by software is not fully guaranteed as it was applied in bad work condition. In order to solve the problem, a method of nonlinearity correction by hardware, is that Complex Programmable Logic Device (CPLD), was put forward. It was shown by turbine flow sensor prototype experiment with electric eddy current pick-up combining CPLD hardware nonlinearity correction. DN4mm, DN6mm and DN10mm turbine flow sensor obtain the linearity 0.32%, 0.26%and 0.32% respectively in the range ability of 10∶1.
