In order to study the distribution of stress and deformation variable cross-section continuous box girder bridge, in this paper, finite element method is used establish model bridge. Considering layout lane load, combination working conditions calculated, bridge are analysed. The results show that maximum generally occurs at beam span middle section or support, sometimes value vehicle load poin...

We consider fluting oscillations in a thin straight expanding magnetic flux tube the presence of background flow. The is divided into core region that wrapped transitional region, where damping takes place. method multiple scales used for derivation system governing equations. This applicable to study both standing and propagating waves. Furthermore, equations obtained tubes with sharp boundary...

The paper utilizes Port State Control inspection data for discovering interactions between the numbers of various types of deficiencies found on ships and between the deficiencies and ship’s involvement in maritime traffic accidents and incidents. Bayesian network models for describing the dependencies of the inspection results, ship age, type, flag, accident involvement, and incidents reported...

INTRODUCTION High levels of rheumatoid factors (RF) are detectable in serum of the majority of patients with rheumatoid arthritis (RA), but 5-10% of patients remain seronegative (SN). Despite clinical and genetic similarities between these two subsets of RA, it has been proposed that they may be regarded as distinct clinical entities. METHODS In the present study a panel of monoclonal antibod...

Is Demand-Pulled Innovation Equally Important in Different Groups of Firms? Previous empirical literature mainly cross-sectional has tested the demand-pull hypothesis and found that overall, evidence does not conflict with the idea that innovation may be driven by output. Using a balanced panel of 216 Italian manufacturing firms over the 1995-2000 period, and checking for fixed effects, time, s...

Development economists have superseded any necessity of using Arrow’s methodological individualism (MI) in focusing on cross-cultural, cross-national, or developmental economics. This study examines whether analysis of cross-cultural economic models might include a concept of economic generosity as a type of economic structuration that deviates from MI principles and is closer to what economist...

A class of Gaussian latent-variable models for cross-covariance is specified, and the set of distributions over the observed variables to which they correspond is precisely characterized. In this class the observed variables, or indicators, are divided into two blocks, X and Y. A pair of latent variables is postulated, one for each block, ξ for X and ω for Y. The indicators are linear functions...

Cross-lagged panel analysis is an analytical strategy used to describe reciprocal relationships, or directional influences, between variables over time. Cross-lagged panel models (CLPM), also referred to as cross-lagged path models and cross-lagged regression models, are estimated using panel data, or longitudinal data where each observation or person is recorded at multiple points in time. The...

The web crossed truss boom is one of the commonly used structures crawler cranes. However, existing calculations fail to consider limiting effect members' bending resistance on chord members, and cannot give full play load-bearing capacity structure. This paper takes top section Crawler crane as research object. single-span theoretical model established according Timoshenko's elastic stability ...
