Severe acute respiratory syndrome (SARS) has claimed 349 lives with 5,327 probable cases reported in mainland China since November 2002. SARS case fatality varied across geographical areas, which might be partially explained by air pollution level. Publicly accessible data on morbidity and mortality were utilized the analysis. Air was evaluated index (API) derived from concentrations of particulate matter, sulfur dioxide, nitrogen carbon monoxide ground-level ozone. Ecologic analysis...
We present a chat system that uses animateddynamic text associated with emotional information to show the affective state of user. The obtains user from physiological sensor attached user's body. This paper describes preliminary experiments and provides examples possible applications our system. Observations informal comparing animated conventional suggest an online interface conveys helps users interact each other more efficiently.
Propagating wavefields from monopole, dipole, and quadrupole acoustic logging-while-drilling (LWD) tools in very slow formations have been studied using the discrete wavenumber integration method. These studies examine responses of monopole dipole systems at different source frequencies a surrounding formation, system operating low frequency formation with S-wave velocities. Analyses are conducted coherence-velocity/slowness relationships (semblance spectra) time domain dispersion...
In the 12th Five-Year Plan, Chinese government set goal of increasing life expectancy by one year. The purpose this study is to examine impact major causes death on people between 1950 and 2010 predict changing trends identify issues requiring future attention. A continuous database organised population data diseases age group were created from Province in Eastern China. classified into four categories International Classification Diseases-10 (ICD-10): infectious parasitic diseases, chronic...
This paper aims to investigate the strength and failure mechanism of fractured rock under seepage pressure. For this purpose, precracked sandstone specimens were prepared with different fissure angles, a pressure loading device was created. Together acoustic emission (AE) system, adopted perform uniaxial compression tests or without The main results are as follows. Combined axial stress‐strain curves, photographic monitoring output AE counts process can be generally divided into four stages:...
Undergraduates doing scientific research is an effective way to cultivate innovative talents.The paper introduces some practices and experiences of Nanjing University Aeronautics Astronautics in strengthening undergraduates' ability as practical school develops a training system cultivating talents, featuring teaching based on engineering practice continuous comprehensive student-centered system.
Abstract Because of a large number Chinese women and the widespread concern about women's living conditions, this study aimed to examine how subjective well‐being mediates association between marital relationship quality life in context. The data used were collected by conducting multi‐stage cluster random sampling method 756 Huai'an city Mainland China. Data included basic demographics, quality, well‐being. Structural equation modeling was adopted analyze data. results structural analysis...
Warping deformation along the length is one of thin-walled C-section composite beam (TC2B). Preloading induced changes in warping should be considered tolerance simulation. The paper presents a simulation for TC2B assembling under preloading. Based on numerical model and small displacement torsor model, preloading-modified probability distribution deviation obtained. assembly downscaled wingbox illustrates effect preloading TC2B. results have shown that with modified more accurate than...
Abstract The technical characteristics of government audits make the purchase social audit services different from other public services. Carrying out performance evaluations outsourced is important for ensuring effective service outsourcing and completing comprehensive high-quality audits. On basis constructing a conceptual framework purchases under background coverage, objectives, principles, processes, models, steps are clarified. From perspective evaluation theory, model an index system...
The suspension spring compression introduce local deformation in the shock tower, and it brings imprecision or uncertainty of computer aided tolerancing (CAT) results assembly. This work presents an integrated motion error analysis method assembly to consider tower. Tolerancing model is constructed CAT software. FEA provides tower introduced by under full loaded condition. represented with modified probability distribution function (PDF) joining point between PDFs points, together...
In the mine construction, surface pre-grouting technology is an important method to prevent water blast in excavation process of vertical shaft when must pass through thick, water-rich and high water-pressure bedrock aquifer. It has been nearly 60 years since was used reform wall rock coal China for first time, existing can basically meet needs constructing 1000m deep shaft. Firstly, article introduces that view Magg's spherical seepage theory Karol's theory, Chinese scholars found diffusion...
According to Gubei Coal Mine 1552 (3) working face soft rock roadway support has different degrees of roof subsidence, floor heaves, and slabs, accompanied by a large number anchor cable breakage failures, through Flac3D numerical simulation, grouting for the With two models full-face grouting, spacing is 3m, 4m, 5m, 6m, three new schemes under environments are obtained. The results show that plastic zone range 3m 4m smallest best control effect on deformation failure roadway. more...
