USING THE ANALYTICAL HIERARCHY PROCESS TO SUPPORT SUSTAINABLE USE OF GEO-RESOURCES IN METROPOLITAN AREAS

1. Introduction Geo-resources like sand and gravel are important raw materials which are mainly needed for concrete production in civil engineering projects. This makes them valuable, especially in metropolitan areas where construction activities are frequent. In spite of their usefulness for construction purposes, their economic value is relatively low so that transporting them over greater distances is normally not profitable in most cases. To be run economically, sand and gravel pits are th…     

Adaptive compensating method for Doppler frequency shift using LMS and phase estimation

The novel compensating method directly demodulates the signals without the carrier recovery processes, in which the carrier with original modulation frequency is used as the local coherent carrier. In this way, the phase offsets due to frequency shift are linear. Based on this premise, the  compensation processes are: firstly, the phase offsets between the base band neighbor-symbols after clock recovery are unbiasedly estimated among the reference symbols; then, the receiving signals symbols are adjusted by the phase estimation value; finally, the phase offsets after adjusting are compensated by the least mean squares (LMS) algorithm. In order to express the compensation processes and ability clearly, the quadrature phase shift keying (QPSK) modulation signals are regarded as examples for Matlab simulation. BER simulations are carried out using the Monte-Carlo method. The learning curves are obtained to study the algorithm’s convergence ability. The constellation figures are also simulated to observe the compensation results directly.

航海模拟器中海洋环境时空动态变化的仿真

海洋结构物始终受到环境干扰,对海洋环境的仿真会显著影响航海模拟器的真实感。基于数值波浪模型生成海洋环境场,并利用SQLite开发实海域数据库。通过数据库中获取实际的风,海流和海浪信息来与真实海洋保持一致。对环境扰动进行建模,并且将时空变化特征和耦合效应都融入仿真。通过提出的仿真方法再现了真实的航行情况,并利用船载传感器的测量数据进行验证。仿真结果与实测数据吻合良好,说明本方法可以进一步提高海洋模拟器的物理真实感。     

Global input-to-state stabilization with quantized feedback for discrete-time piecewise affine systems with time delays

In this paper, global input-to-state stabilization with quantized feedback for discrete-time piecewise affine systems （PWA） with time delays are considered. Both feedback with time delays and feedback without time delays are considered. Piecewise quadratic ISS-Lyapunov functions are adopted. Both Lyapunov-Razumikhin and Lyapunov-Krasovskii methods are adopted. The theorems for global input-to-state stabilization with quantized feedback of discrete PWA systems with time delays are
