The research designed controllers for buildings which are subjected to earthquakes. The designed nonlinear controllers ought to be able to significantly reduce the floor displacements when a building is subjected to earthquakes. All the controllers were simulated based on the…

SVM and Simulated Annealing Algorithms were applied to grid resources prediction. In order to build an effective SVR model, the parameters must be selected with attention. Here, a simulated annealing algorithm-based SVR (SA-SVR) model has been developed to determine the…

In order to save energy of the aluminum industrial production, the K-means algorithm and threshold cluster analysis algorithm were used, and the classification of the energy consumption data of the aluminum industrial production is completed with Matlab simulation. We compared…

Computer Aided Instruction (CAI) is the very important application field of engineering. Computer auxiliary examination management system is the important link of the Computer Aided Instruction, and it is an effective means for teaching evaluation. We found an application of…

In this paper, an investigation for the enhancement strategy of bandwidth performance and analysis of different types of losses associated with reflectarray antennas was carried out. Studies are carried out using different commercially available dielectric materials with dielectric permittivity values.…

It is widely agreed that the radio waves are more complex in confined environments, such as coal mine tunnels and buildings. In this paper tried to interpret propagation characterists of radio wave in the confined environments of mine tunnel. We…

System error measurement is the essential step in actuator frequency characteristic testing and is studied to provide qualified results for system error compensation. We explored the approaches using swept sine and fast Fourier transform. We found that digital smoothing is…

In this paper, we designed a controller for an interval system and fixed cost function. The closed-loop system stability and cost function is guaranteed to be no more than a certain upper bound with all admissible uncertainties as well as…

The growing demand of digital oilfield in oil and gas industry leads extensive research on the development of engineering software for the analysis of real-time oil and gas drilling data. The Intelligent Drilling Advisory system is an engineering software and…

With the growing demand for real time services in wireless sensor networks, quality of service based routing has attracted more attention. But offering some quality of service guarantee in sensor networks raises significant challenges. The network needs to cope with…
