Full 3D interpretation must be based on really full 3D horizons interpretation. In this paper, we used mathematical model of the similarity principle which express the characterization of the waveform similarity of seismic data, and we analyzed the effect of model parameters on the waveform similarity recognition, then we applied this method to auto-track the reflected wave of coalseam in the 3D seismic...
Catalyst dense loading of an oval loading device was simulated based on the basic principle of discrete element method (DEM). Effects of rotation speed of the loader and the radius of the catalyst particles were analyzed. The results showed that catalyst loading speed was not equal to outflow speed of the hopper, it increased with the increase of the rotation speed and decreased with increase of the...
An unsteady-state mathematical model of the heat transfer and flow of the integrated system under no-load condition has been developed. The influence of heat collector structural parameters on the system has been researched. The results show that the negative pressure, draft force, velocity and airflow temperature rise of integrated system increase significantly with the increasing of collector diameter...
An unsteady-state mathematical model of the heat transfer and flow of the integrated system under no-load condition has been developed. The field distribution characteristics of the pressure, velocity and temperature of the integrated system have been researched. An optimization method based the temperature field distribution at the region where the wind turbine is placed has been proposed. The results...
Cerium incorporated ordered manganese oxide OMS-2 type catalysts containing cerium with different cerium contents in the form of incorporated cations were synthesized. The physicochemical properties of the materials were investigated employing XRD and FTIR. Catalytic activity was tested in the selective vapor phase oxidation of toluene to Benzaldehyde. Effects of content of cerium, reaction temperature,...
Localized induction heating for wafer level packaging is discussed. This paper is to investigate the relationships between the geometry of solder loop and temperature distribution in induction heating. Using finite element method (FEM) and IR thermal imager, temperature distribution and variation are explored, which shows that the temperature on the solder loops is a function of the area and edge...
Selective induction heating for wafer level bonding is presented. The purpose of this paper is to investigate the relationships between the geometry of solder loop and temperature distribution in induction heating.

Conventional Savonius rotor is a ldquoS-shapedrdquo cross-section rotor, the power performance coefficient (CP=0.15) is rather low. This study introduces a new type-helical Savonius rotor, applies calculation fluid dynamics (CFD) to analyze and improve the performance of the rotor from aspects ratio(H/D), number of blades, overlap distance and helical angle(thetas). The results show the performance...
In this paper, a non-linear and one-directional coupled finite element framework has been implemented to simulate induction heating process of wafer-level packaging. Based on numerical results of induction heating, thermally-caused warpages and stresses of the single-sided ceramic wafer have been evaluated. Some primary experiments have also been conducted to verify the numerical method. Using three-dimensional...
Highway has become an important traffic way, large number of cars are running on highway everyday, and a convenient and fast method for highway toll is an important research aspect in intelligent transportation system (ITS). radio frequency identification (RFID) technology used in highway electronic toll collection (ETC) system is a new research field. This paper introduces the RFID antenna design...
