Published: February 2014

The corridor is an important way of evacuation and rescue in building fire. The fire smoke flow prediction software developed successfully was applied to simulate a building with a 28.8 meters long corridor to investigate the effect of the different thermal insulation on fire smoke spread rate. Two representative thermal insulation, external insulation and internal insulation were compared. In 3600s fire time, air temperature in the corridor of external insulation is much lower than that of internal insulation. The air temperature gap gets narrowed between the two insulation methods in the corridor with the prolongation of fire time. Temperature difference increases as the distance increase from the fire ignition place. The corridor gets unsafe of internal insulation in 7 minute since fire ignition, while about half the length of the corridor stay secure of external insulation in 10 minutes since fire ignition. That implies more available safe egress time can be gained with external insulation than internal insulation. Smoke spread rate was numerically compared based on the air temperature variation. Smoke spread rate of internal insulation is much higher than that of external insulation and the corresponding ratio is 1.732:1.

Authors: Chen Jia Yin , Liu Guo Jun
Published: February 2014

Surface plasmon polariton (SPP) waves exhibit local characteristics that can break diffraction limits; for this reason, the production of subwavelength optoelectronic device has been the focus of current studies. To determine the importance of surface plasmon wave applications, we aim to investigate whether or not the theoretical dispersion obtained in the plasma and metal (Drude model) exhibits the same expression, satisfy the relationship of SPPs by controlling the electron density of the plasma and the frequency of the incident electromagnetic wave, and derive the system performance parameters and plasma density parameters by changing the grating geometry and dielectric constant of the surrounding medium by using the grating structure based on surface plasmon propagation characteristics associated with sensor research. The simulation results of then design structure showed that transmission bandwidth rapidly decreases and transmission peak gradually decreases as metal dielectric thickness decreases. An SPP sensor can effectively eliminate light instability in the two wavelengths of light intensity difference to obtain anti-interference and improve the range of the measuring instrument by using two fiber-grating structure filters. Therefore, studies on surface plasmon devices for integrated application are of promotional importance.

Authors: Wang Xin Rui , Yang Yun Feng
Published: February 2014

A novel medical image retrieval method based on Simplified Multi-wavelet Transform and Shape Feature was proposed in the paper, which included coarse and fine retrieval procedure. In the procedure of the coarse retrieval, Canny operator was used to extract edges of images. Moreover, contour lines were obtained by using the method of scan lines. At last, the coarse retrieval results of the images can be accomplished by using contour lines of images. In the procedure of the fine retrieval, the simplified multi-wavelet transform was used to decompose images at first, then, only the high frequency coefficients in the vertical directions were selected as retrieval objects. And hierarchical retrieval strategy was selected to accomplish the fine retrieval. This method not only can reduce the computational complexity effectively, but also can make full use of high frequency information of original images. Experiments showed that the accuracy of the retrieved results can be ensured.

This paper design a portable ECG monitor based on mobile phone. Using the single-lead heart rate monitor analog front-end of AD8232 chip produced by ADI co. Ltd., the monitor can measure human ECG signal and heart rate with only two electrode pads placed on chest, and display the ECG signal on the mobile phone via Bluetooth communication in real time. It also can simply measure the heart rate by touching the two electrodes of the monitor directly. The system has many functions like ECG signal analysis, heart rate counting, arrhythmia detection, signal playback, leads off detection, fast recovery ECG. The result shows that the portable ECG monitor is low cost, low power consumption, small size and easy to carry, etc.

A novel visual tracking algorithm based on particle filter with multi-algorithm fusion is proposed. Mean shift is employed to make particles distribute more reasonably in order to maintain tracking accuracy by using fewer particles, and the genetic evolution ideas is introduced to increase the diversity of samples by applying selection, crossover and mutation operator to achieve particles resampling. The experiments show that the tracking performance of the proposed method, compared with Mean Shift Embedded Particle Filter (MSEPF), is significantly improved.

Based on ideal point principle, an economic/environmental dispatch model considering valve point effects was constructed. The model combined optimization and decision-making process of multi-objective optimization problem and its dynamic transformation can be achieved simply by changing the weights of each of the target model. The adaptive immune vaccine algorithm was applied to optimizing the model. Meanwhile, the target expected completion rate was brought up to measure the completion degree of the environmental and economic indicators. The simulation results showed that the method proposed can reduce the pollution of the environment effectively with low fuel cost.

This paper was presented one new modified controller scheme for inertial gyro control system. Based on Narendras hybrid adaptive law, the modified algorithm was variable metric that took use of parameter matrix Γk to obtain two updating laws in turn online. The key modified contents were: 1) the output y (t) was passed by one low-pass filter, 2) the parameter was updating in term of one proper initial Γ0 and the measurable values. The objective of the proposed new adaptive robust control schemes was to achieve fast convergence of parameter updating, and promise good robust stability of control system during tracking, reduce the tracking error at start-time with filtered output.

With some residual coal and much leaking air in gob area, fire happens frequently in those areas. Thus, it has become one of main factors of restricting mine development. With the technology of optical fiber pyrometer, the monitoring system has been designed for temperature distribution in coalmine gob area. In addition, by combining it with line laying system, power supply system, data collection system and data analysis system, temperature distribution in coalmine gob area could be monitored in time to provide firing warning of the spontaneous fire happening in the residual coal and fire would be reduced effectively. By comparing optical fiber thermometric system with the temperature measurement system, it shows that the former have a clear advantage in the aspects of time, the location of ignition point, reaction speed and costs maintenance.
