Fault Type Analysis along the San Andreas Fault Zone: A Numerical Approach

Finite Element (FE) modeling under plane stress condition is used to analyze the fault type variation with depth along and around the San Andreas Fault (SAF) zone. In this simulation elastic rheology was used and was thought justifiable as the variation in depth from 0.5 km to 20 km was considered. Series of calculations were performed with the variation in domain properties. Three types of models were created based on simple geological map of California, namely, 1) single domain model considering whole California as one homogeneous domain, 2) three domains model including the North American plate, Pacific plate, and SAF zone as separate domains, and 3) Four domains model including the three above plus the Garlock Fault zone. Mohr-Coulomb failure criterion and Byerlee's law were used for the calculation of failure state. All the models were driven by displacement boundary condition imposing the fixed North American plate and Pacific plate motion along N34°W vector up to the northern terminus of SAF and N50°E vector motion for the subducting the Gorda and Juan de Fuca plates. Our simulated results revealed that as the depth increased, the fault types were generally normal, and at shallow depth greater strike slip and some thrust faults were formed. It is concluded that SAF may be terminated as normal fault at depth although the surface expression is clearly strike slip.

Experimental and numerical analysis of secondary disasters induced by oxygen rich combustion within a tunnel

Various physical parameters, including gas concentrations (O2, CO, CH4, and H2) and temperatures at dif- ferent air velocities, were determined for full scale wood fires in the Chongqing Coal Research Institute fire test tunnel. Both experimental measurements and numerical simulations are discussed. The numer- ical analysis was performed with the computational fluid dynamics software package ''FLUENT''. The results show that the experimental data agree with the simulation results. The results verify that Roberts' theory of burning is correct. They also prove that the air velocity is the key factor that determines the type of combustion. Also, it is shown that secondary disasters are unlikely for oxygen rich combustion with a limited fire load.

Pressure Buildup Analysis Using Type Curves for a Well in a Pressure-Maintained System

The development and application of a new solution is demonstrated for the type-curve analysis and in-terpretation of well test data from a multiwell reservoir system of both production and injection wells with two-phase flow. The buildup type curves or buildup behavior could be obtained through the solution by using su-perposition. But a new outer boundary condition for variable pressure boundary must be introduced to obtain the correct pressure buildup solutions by superposition. A technique is shown to determine the deviation time from the infinite-acting semilog radial flow stabilization in the derivatives of pressure, which is calculated with respect to and plotted vs. shut-in time. Field examples are given to illustrate the use of the proposed method for analyzing transient pressure data from a well located in a multi-well water-injection reservoir. An adaptive genetic algorithm-based method is used to match the pressure and pressure derivative data to estimate reservoir parameters. The validity and applicability of the proposed method are also demonstrated through the examples.

A Spectral Analysis of 155 Seyfert 1 Type AGN

We present the results of optical spectral analysis of a sample of 155 bright X ray selected ROSAT Seyfert 1 type AGN. We measured emission line properties by performing multi component fits to the emission line profiles, covering the effect of blended iron emission. We also obtained continuum parameters, including 250eV X ray luminosities derived from the ROSAT database. The measured properties are gathered for correlation analysis. Strong correlations between Hβ redshift, flux ratios of Fe Ⅱ to Hβ broad component and to Hβ narrow component are found. The observed trends are most likely driven by the Eddington ratio.

Phylogenetic analysis of the genomes of two strains of human adenovirus type 3

Human adenovirus type 3 （HAdV-3） is widely prevalent all over the world, especially in Asia. The objective of this study is to carry out complete genomic DNA sequencing and the phylogenetic analysis for two strains （Guangzhou01 and Guangzhou02） of HAdV-3 wild virus isolated from South China. Nasopharyngeal secretion aspirate specimens of sick children were inoculated into HEp-2 and HeLa culture tubes, and the cultures were identified by neutralization assay with type-specific reference rabbit antiserum. Type-specific primers were also utilized to confirm the serotype. The restriction fragments of HAdV genome DNA were cloned into pBlueScript SK （ ＋ ） vectors and sequenced, and the 5＇ and 3＇ ends of the linear HAdV-3 genome were directly sequenced with double purified genomic DNA as templates. General features of the HAdV-3 genome sequences were explored by using several bio-software. Phylogenetic analysis was done with MEGA 3.0 software. The genomic sequences of Guangzhou01 and Guangzhou02 possess the same 4 early regions and 5 late regions and have 39 coding sequences and two RNA coding sequences. Other non-coding regions are conservative. Inverted repeats and palindromes were identified in the genome sequences. The genomes of group B human adenovirus as well as HAdV-3 have close phylogenetic relationship with that of chimpanzee adenovirus type 21. The genomic lengths of these two isolated strains are 35 273 bp and 35 269 bp, respectively. The phylogenetic analysis showed that HAdV-B species has some relationship with certain types of chimpanzee adenovirus.

A comparative study on crash-influencing factors by facility types on urban expressway

This study aims at identifying crash-influencing factors by facility type of Nagoya Urban Expressway, considering the interaction of geometry, traffic flow, and ambient conditions. Crash rate （CR） model is firstly developed separately at four facility types： basic, merge, and diverge segments and sharp curve. Traffic flows are thereby categorized, and based on the traffic categories, the significances of factors affecting crashes are analyzed by principal component analysis. The results reveal that, the CR at merge segment is significantly higher than those at basic and diverge segments in uncongested flow, while the value is not significantly different at the three facility types in congested flow. In both un- and congested flows, sharp curve has the worst safety performance in view of its highest CR. Regarding influencing factors, geometric design and traffic flow are most significant in un- and congested flows, respectively. As mainline flow increases, the effect of merging ratio affecting crash is on the rise at basic and merge segments as opposed to the decreasing significance of diverging ratio at diverge segment. Mean- while, longer acceleration and deceleration lanes are adverse to safety in uncongested flow, while shorter acceleration and deceleration lanes are adverse in congested flow. Due to its special geometric design, crashes at sharp curve are highly associated with the large centrifugal force and heavy restricted visibility.

Acoustic emission assessment of interface cracking in thermal barrier coatings

In this paper,acoustic emission（AE） and digital image correlation methods were applied to monitor interface cracking in thermal barrier coatings under compression.The interface failure process can be identifie via its AE features,including buckling,delamination incubation and spallation.According to the Fourier transformation of AE signals,there arefourdifferentfailuremodes：surfaceverticalcracks,opening and sliding interface cracks,and substrate deformation.The characteristic frequency of AE signals from surface vertical cracks is 0.21 MHz,whilst that of the two types of interface cracks are 0.43 and 0.29 MHz,respectively.The energy released of the two types of interface cracks are 0.43 and 0.29 MHz,respectively.Based on the energy released from cracking and the AE signals,a relationship is established between the interface crack length and AE parameters,which is in good agreement with experimental results.

Plate reinforced square hollow section X-joints subjected to in-plane moment

The static test of 13 square hollow section(SHS) X-joints with different β and different types of plate reinforcement under in-plane moment in brace was carried out. Experimental test schemes, failure modes of specimens, moment-vertical displacement curves, moment-deformation of the chord, and strain strength distribution curves were presented. The effect of β and plate reinforcement types on in-plane flexural property of SHS X-joints was studied. Results show that punching shear of chord face disappears, brace material fracture appears and concave and convex deformation of chord decrease when either collar plates or doubler plates were welded on chord face. Moment-vertical displacement curves of all specimens have obvious elastic, elastic-plastic and plastic stages. As β increases, the in-plane flexural ultimate capacity and initial stiffness of joints of the same plate reinforcement type increase, but ductility of joints decreases. With the same β, the in-plane flexural initial stiffness and ultimate capacity of doubler plate reinforced joints, collar plate reinforced joints, and unreinforced joints decrease progressively. Thickness of reinforcement plate has no obvious effect on in-plane flexural initial stiffness and ultimate capacity of joints. As thickness of reinforcement plate increases, the ductility of reinforced X-joints decreases. The concave and convex deformation of every specimen has good symmetry;as β increases, the yield and ultimate deformation of chord decrease.

This implies the for some β(0<β<2:1+ε), the dynamicalbehavior of the J-J equation is rather complex.

Fault Location and Classification for Distribution Systems Based on Deep Graph Learning Methods

Accurate and timely fault diagnosis is of great significance for the safe operation and power supply reliability of distribution systems.However,traditional intelligent methods limit the use of the physical structures and data information of power networks.To this end,this study proposes a fault diagnostic model for distribution systems based on deep graph learning.This model considers the physical structure of the power network as a significant constraint during model training,which endows the model with stronger information perception to resist abnormal data input and unknown application conditions.In addition,a special spatiotemporal convolutional block is utilized to enhance the waveform feature extraction ability.This enables the proposed fault diagnostic model to be more effective in dealing with both fault waveform changes and the spatial effects of faults.In addition,a multi-task learning framework is constructed for fault location and fault type analysis,which improves the performance and generalization ability of the model.The IEEE 33-bus and IEEE 37-bus test systems are modeled to verify the effectiveness of the proposed fault diagnostic model.Finally,different fault conditions,topological changes,and interference factors are considered to evaluate the anti-interference and generalization performance of the proposed model.Experimental results demonstrate that the proposed model outperforms other state-of-the-art methods.

The Functional Approach to the Teaching of Translation: A Case Study on Beiying and Its English Translations

This paper reports the attempt to apply the functional approach to the translation teaching practice that guides students in their study of Chinese essays and their English translations. The famed modern Chinese essay Belying and its three English translations were taken for case study from the perspective of Experiential Function in Systemic Functional Linguistics. A process type analysis of Beiying and its English translations was conducted, including analysis of texts, sample processes, distributions of process types in Beiying and analyses of similarities and differences in the distributions. Results are as follows： 1） The similarities between English and Chinese texts lie in the experiential world, which makes translation possible. The process types in the essay text are directly related to genre, and the material process predominates among the process types in essay texts. 2） The differences are that the percentage of the material process in the ST is higher than that in the three English translations, and this shows the characteristics of verb-prominence in Chinese and nominalization in English. 3） Cultural differences in translation are the root-cause of linguistic differences. These results from the case of practicing the functional approach to the teaching of translation can help students gain understanding of English translations of Beiying and can provide some inspiration for the teaching of Chinese-English essay translation and the related studies.
