Garmsar block is located in Central Iran Basin, and the geological prospecting in this area is in the early stage. Late research reveals this area is potential oil-bearing and some reservoirs have been found in adjacent areas in Central Iran Basin. Qom Formation is proven that has the potentiality of self-generation and self-accumulation. The depositional setting and sedimentary-tectonic setting in...
The Paleogene of the east sag is in the rift period of the lake basin, which is subjected to the effect of the bedrock burial hill and the east branch of the Tan-Lu faulted zone, with the layers present the half graben rift, which is break in east and overlap in west. According to the distribution of the main synsedimentary faulting in the plane and profile, the half graben rift can be further divided...
Generally, the horizontal gravity gradient map resulted from Bouguer anomaly reflect quite well the planar distribution of the faults with large scale in the area of XX block under study. But volcanic rocks developed at some locations in Eocene may disturb, to some extent, the extraction of fault information from gravity anomalies, therefore only gravity data are constrained for proper interpreting...
Based on the neural network theory, this paper proposes the neural network model to solve the surrounding rock displacement prediction of nonlinear problems. This model combines the advantages of wavelet time-frequency analysis and neural network self-learning. The studies had shown that the wavelet neural network had higher prediction accuracy. In addition, it could better reveal the changes of displacement...
At present, as a new trend of the telecommunication industry, mobile application requires refine the technique of data management continuously, therefore, mobile database has been come into being. The thesis mainly focused on the introduction of mobile database and the characteristics of data management, especially analyzed the architecture and functions of the SQL Server CE. On this basis, according...
The allocation of emergency resources is an important part of emergency decision. In this article, a dynamic programming model and goal programming model of emergency resources were presented. At the same time, aiming at solving the faultiness and inflexibility, the article presents a method of making multi-stage emergency decisions based on the theory of risk analysis and repast symphony platform...
The temperature and voltage fluctuation characteristics of pressure sensor was analyzed and found that the sensor output is nonlinear and easy to be affected by temperature and voltage fluctuation over a wide measuring range, a correction model of pressure sensor based on Support Vector Machine was presented. The approximate ability of the SVM to any nonlinear function was utilized to drill the correction...
This paper expounded the basic principle of phase interferometer system, established positioning model of one-dimensional double-base line, improved the bearing accuracy and solved the fuzzy problem. The whole circuit of the positioning system was designed, radio signal communication was implemented by RF transceiver chip, low frequency signal was used as signal frequency to modulate it to carrier,...
Generally, the local structures are studied from second vertical derivative gravity anomaly in reconnaissance survey because of shortage of seismic data and other information. But if igneous rocks are pervasive, thick and large enough, it causes gravity anomalies with a certain extent sizes and amplitudes. So when we start the research of the local structures in this stage, we need to synthetically...
The projective recovery of 3D point structure from multiple images has been one of the classical problems in computer vision. Existing methods for projective reconstruction usually require a priori estimation of a consistent set of projective depths which in turn require the estimation of the projection matrices or the fundamental matrices in advance. Those methods are usually nonlinear, time-consuming,...
SPEEX is a flexible codec based on the Code Excited Linear Prediction (CELP) algorithm and supports a wide range of speech quality. In this paper, several high-level and low-level optimization techniques have been concurrently employed to reduce the MIPS count and complexity of the SPEEX decoder in order to achieve good speech quality on an embedded DSP receiver. We reassign the decoder's stack and...
A W-band VCO MMIC is first time reported in this paper in China, To eliminate the parasitic resistance of the oscillator loop, this chip utilizes the source capacitive feedback forming the negative resistance. Through the reasonable output matching network, the chip also realize the frequency start-up condition and restrain the output harmonic. Finally, Fabricated by the NEDI's 0.15 um GaAs MHEMT...
In this research, which takes the ‘12.23’ Kaixian blowout accident in Chongqing as an example, firstly the basic information of the accident, including the affected area, the accident process and the accident consequences, was described. Secondly, the development of the accident and other correlative things were researched in detail, especially the monitoring result of concentrations of toxic gases...
Because the method of azimuth measurement by the zero point in TACAN has the problems such as large error and weak noise immunity, an accurate measurement method based on sine wave curve-fitting is discussed according to the character of TACAN signal. Least square algorithm is used to estimate parameters of the curve and the error between the signal and the fitted curve is calculated. The measured...

Landform feature lines, as one kind of descriptors of landform skeletons, have been used in many fields, such as surveying, hydrology simulation, landform classification, and vegetation mapping. Due to the fuzziness and multi-scale characteristics of landform features, there are still some obstacles in the process of landform features exaction. The main weakness includes spatial extent, the vagueness...
