Time—varying, nonlinear and multivariable coupling are characteristics of temperature. In the temperature control process, the detected temperature is often lags behind the regulation of temperature, which will cause the phenomenon such as the temperature of the controlling system overshoot and temperature...

Nowadays, the Direct-Sequence Spread Spectrum (DSSS) technology has been widely used. It's urgent to research blind detection algorithms on DSSS signal. In this paper, a new method is proposed. It based on a combination of wavelet noise reduction and Estimation-based Time-domain Sliding Correlating Accumulation,...

The High-speed development of Self-regulation temperature control technique gives a lot convenience to most people. Essentially people feel the temperature of water by personal perception. This article discusses the circumstances that people use personal feeling to make a judgment and manual control...

This paper discussed the design of a 0.18 m CMOS process 5.8GHz RF front-end circuit, and the simulation and experiment were carried out. The main circuit design are low noise amplifier and mixer, the noise amplifier is overlay architecture, and using dual output mode single input / transformer coupling;...

The flooding method is utilized to forward the acknowledge message to delete the redundant copies of message. As a result, lots of network resources will be consumed by this kind of operation. A novel message deletion mechanism is proposed in this paper. Taking into account the hop count of ACK message,...

There is a cooperative willingness perception based routing algorithm is proposed in this paper. The average duration of messages forwarding is utilized to measure the cooperative willingness between nodes; moreover combining with the parameter of contact probability between nodes, the relay node can...

Change detection is an ongoing hot topic in multi-spectral imagery applications, how to exploit the available spectral information effectively for change detection is still an open question. Considering the noise interference and redundancy of multi-spectral imagery, it is important and necessary to...

Role car ESP hydraulic system is applied to the appropriate wheel hydraulic braking force, the implementation of active intervention of the vehicle, so that the car during braking, good stability, and therefore directly affect the effective control of the ESP braking car security. Thesis for the dynamic...

Establish two class operational effectiveness evaluation index system of smoke support system, and based on classic smoke support operational scenario, according to system simulation method, conduct program inferring and deducting and evaluate smoke operational effectiveness by integrating it into full...
