A frequency domain method for estimating wind-induced fluctuating internal pressure of structure with single windward opening is presented in this paper and wind tunnel tests were carried out to verify the theory. The nonlinear differential equation of internal pressure dynamics and iteration algorithm were applied to calculate fluctuating internal pressure and time domain analysis was used to verify the accuracy of the proposed method. A simplified estimation method is also provided and its scope of application is clarified. The mechanism of internal pressure fluctuation is obtained by using the proposed method in the frequency domain and a new equivalent opening ratio is defined to evaluate internal pressure fluctuation. A series of low-rise building models with various openings and internal volumes were designed for wind tunnel tests with results agreeing well with analytical results. It is shown that the proposed frequency domain method based on Gaussian distribution of internal pressure fluctuations can be applied to predict the RMS internal pressure coefficient with adequate accuracy for any opening dimensions, while the simplified method can only be used for structure with single dominant opening. Helmholtz resonance is likely to occur when the equivalent opening ratio is adequately high, and controlling individual opening dimension is an effective strategy for avoiding Helmholtz resonance in engineering. 展开更多

This study aims to develop a framework based on the Nadal formula to assess train derailment risk. Monte Carlo simulation was adopted to develop 10000 sets of random parameters to assess train derailment risk subject to the curvature radius of the track, the difference between the flange angle and the equivalent conicity, and accelerations from 250 to 989.22 gal during horizontal earthquake. The results indicated that railway in Taiwan, China has no derailment risk under normal conditions. However, when earthquakes occur, the derailment risk increases with the unloading factor which is caused by seismic force. The results also show that equivalent conicity increases derailment risk;as a result, equivalent conicity should be listed as one of maintenance priorities. In addition, among all train derailment factors, flange angle, equivalent conicity and unload factors are the most significant ones. 展开更多

This study focused on developing a risk assessment method for explosion at a coal reclaim tunnel (CRT) facility. The method was developed based on an analytical hierarchy process (AHP), which is an expert system that quantifies the factors of explosion incidents, based on events and hierarchies. In this paper, the proposed model was modification from original AHP model, specifically modifying the structure from "alternative's results" to "total risk-rating's results". The total risk-rating is obtained by summing up risk-rating of each factor, where the risk-rating is a multiplication product of the risk value by the AHP weighted value. To support decision-making using the expert system, data on the real conditions of the CRT were collected and analyzed. A physical modeling of the CRT with laboratory-scale experiments was carried out to show the impact of a ventilation system in CRT on diluting the methane gas and coal dust, in order to support the quantification of AHP risk value. The criteria to evaluate the risk of explosion was constructed from six components that are: fuel, oxygen, ignition, confinement, dispersion, and monitoring system. Those components had fifty-two factors that serve as sub-components (root causes). The main causes of explosion in CRT were found to be: mechanical ventilation failure and abnormal ventilation, breakdown of monitoring system, and coal spontaneous-combustion. Assessments of two CRT facilities at Mine A and Mine B were carried out as a case study in order to check the reliability of the developed AHP method. The results showed that the risk rating of Mine A was classified as high and Mine B was classified as medium, which is in a good agreement with the site conditions. 展开更多

Firstly, typical features of a supercell, which occurred in Guangzhou on August 11, 2004, are discussed by using the new generation weather radar data. V-notch, finger-echo, weak echo region, overfiang and echo-wall are observed from reflectivity products. A vertical cross section of the radial velocity is made along the direction of the low-level inflow and across the maximum reflectivity core, which displays a part of strong updraft and downdraft. Secondly, a 3-D convective storm model is used to simulate the supercell. The maximum reflectivity and the core thickness of the simulated radar echo are 75 dBz and 14km, respectively. These values are more than the counterparts that are detected by radar. The reason is that attenuation is not calculated in the model. The wind field structure is also given when the storm is the strongest. Divergence, caused by thunderstorm outflow, is in the low level. In the middle and high level, convergence is dominant, but the plume is not simulated at the top. Finally, the evolution of the simulated vertical motion is documented. The interaction between the environmental wind and the updraft, which is formed by the convergence on the ground at the beginning, makes the storm stronger. Then, downdraft occurs and grows. When it becomes dominant, the supercell collapses. 展开更多

Methods that can efficiently model the effects of rock joints on rock mass behavior can be beneficial in rock engineering. The suitability of equivalent rock mass(ERM) technique based upon particle methods is investigated. The ERM methodology is first validated by comparing calculated and experimental data of lab triaxial compression test on a set of cylindrical rock mass samples, each containing a single joint oriented in various dip angles. The simulated results are then used to study the stress-strain nonlinearity and failure mechanism as a function of the joint dip angle and confining stress. The anisotropy and size effects are also investigated by using multi-scale cubic ERM models subjected to triaxial compression test. The deformation and failure behavior are found to be influenced by joint degradation, the micro-crack formation in the intact rock, the interaction between two joints, and the interactions of micro-cracks and joints. 展开更多

P2P network lending refers to the individual through the oJfline trading platform provided by the Business Company provides small loans to other individuals. According to the sea tree Lingyi data stalistics, as of November 2014. China has 1371 P2P network lending company, than by the end of2013 638 over more than doubled. Since 2014,The cumulative volume of the whole network lending industry is up to 431.2 billion yuan. With the increasing social awareness in the industry, the future of the number and amount of P2P network lending companies in China will continue to grow rapidly. However, at present our P2P network credit risk management issues is serious, lacking of professional risk management personnel,who audit on the borrower's credit mostly limited to the upload information of borrowers. Credit rating is largely dependent on the subjective judgment of the risk control personnel and audit staff, which can not meet the requirements of the transaction participants in the loan security measures.This paper to pat the loan company were empirical research, through the logistic model to find the breach the key influence factors, to construct the borrower's credit risk evaluation methods, and to provide the P2P network lending risk control with specific policy recommendations. 展开更多

Since Korea-Japan annexation in 1910, Japan has promoted the migration and/or tourism into colonial Chosun (old Korea) as an efficient cultural strategy for extending imperialism into Korean peninsula. In many tour guide books, the gisaeng (Korean female entertainers) was not only a symbol of Chosun tradition, but a main icon of Chosun tourism. The high class Korean-styled restaurants (yorijoem) were established as tourist attraction for Japanese inlanders, with singing and dancing gisaengs, ondol (Korean heating floor) house and Korean authentic cuisine, etc. The aim of this paper is firstly to explore the existential change of gisaengs in the yorijoem through its spatial significance in the 1930s, and secondly to explore the identity of Seoul local food culture and its metamorphosis under the colonial modernity. 展开更多

AIM: To investigate the allele and genotype frequencies and associated risk of interleukin (IL)-8-251T>A polymorphism on colorectal cancer (CRC) susceptibility risk. METHODS: Peripheral blood samples of 255 normal controls and 255 clinically and histopathologically confirmed CRC patients were genotyped for IL-8-251T>A polymorphism employing allele-specific polymerase chain reaction. The relative association of variant allele and genotypes with CRC susceptibility risk was determined by calculating the odds ratios (ORs). Corresponding χ 2 tests on the CRC patients and controls were carried out and 95% confidence intervals (CIs) were determined using Fisher's exact test. The allele frequencies and its risk association were calculated using FAMHAP, haplotype association analysis software. RESULTS: On comparing the frequencies of genotypesof patients and controls, the homozygous variant AA was significantly higher in CRC patients (P = 0.002) compared to controls. Investigation on the association of the polymorphic genotypes with CRC susceptibility risk, showed that the homozygous variant IL-8 -251AA had a significantly increased risk with OR 3.600 (95% CI: 1.550-8.481, P = 0.001). In the case of allele frequencies, variant allele A of IL-8 -251 showed a significantly increased risk of CRC predisposition with OR 1.32 (95% CI: 1.03-1.69,P = 0.003). CONCLUSION: Variant allele and genotype of IL-8 (-251 T>A) was significantly associated with CRC susceptibility risk and could be considered as a high-risk variant for CRC predisposition. 展开更多

Plasma torch is a device that transforms electrical energy into heat carried by a gas and its safe operation is necessary to control her temperature. This paper presents the use of the Arduino board in temperature control of a plasma torch through fuzzy control. The plasma torch of this project was built so that a flow of water can circulate through your body, allowing its cooling. The cooling system mounted consists of one radiator, one expansion vase, one water pump and one temperature sensor. The heated water coming the plasma torch is passed by the temperature sensor. This is converted in a voltage and read by an analog input port of the Arduino. This processes the information received and makes the decision to turn on/off the radiator fan and/or powered the frequency inverter water pump to control the temperature. The graph of the fuzzy control showed an oscillation between 104 °F to 122 °F around the chosen reference 113 °F. The results show that it is possible to control the temperature of a plasma torch using the Arduino board and fuzzy logic. 展开更多

Objective. To explore the role of HLA- DRBI genes in the development of rheumatoid arthritis(RA) and the orrelations between HLA-DR alleles and clinical manifestations of patients with RA.Methods. 86 patients with rheumatoid arthritis and 106 race matched controls were studied in whom HLA-DR typing was perfomed by the method of DNA amplification with sequence-specific primers(PCR-SSP). The subtypes of HLA- DR4 were determined by the method of hybridization of PCR products with sequence- specific oligonucletides(PCR-SSO) . The absence or presence of HLA-DR4 and its subtypes was correlated with the clinical and serological characteristics of the patients.Results. Compared with controls, an increased gene frequency of HLA-DR4 (48. 8% vs 17. 9 % , P<0. 001) and a decreased frequency of HLADR7 ( 16. 3% vs 27. 4 % , P = 0. 06 ) were found. The DRB1.0405 account for 61. 9 % of DR4+RA patients and 21. 1% of DR4+ controls(P<0. 01 ). There was no difference between the DR4+ and DR4- patients with respect to age ,sex ,duration of disease ,rheumatoid factor (RF) ,extra-articular manifestations including secondary Sjogren' s syndrome. According to the wrist X- ray stage,the patients of DR4+ were more severe than that of DR4- (P<0. 05).Conclusicon. HLA-DR4 and DR4 subtype of DRB1 0405 are related to the development of RA in Chinese. HLA-DR4 can be a useful prognostic marker in the patients with RA. 展开更多
