realistic prediction of concrete shrinkage and creep requires the calculation of the distributions of relative humidity at various times. although the distributions of the relative humidity can be computed by numerical methods from the differential equation for diffusion, simple prediction formulas can facilitate structural analysis. the purpose of this paper is to present a simple formula for ...

This paper presents a finite element formulation for the dynamics analysis of the steady and transient states of a nonlinear piezoelectric beam. A piezoelectric beam with damping is studied under harmonic excitation. A numerical method is used for this analysis. In the paper, the central difference formula of four order is used and compared with the central difference formula of two order in th...
We proposed an approach in modeling and analysis of workflow based on temporal logic of action. A workflow model is divided in to two parts: the description of scheduler as well as database updating and the description of properties, each part is expressed in a TLA formula. The analysis of properties is composed by scheduling analysis and database properties analysis and their proof process is ...
BACKGROUND The association between infant formula feeding at birth and subsequent feeding patterns in a low- or middle-income context is not clear. OBJECTIVE We examined the association of infant formula feeding during the first 3 d after birth with subsequent infant formula feeding and early breastfeeding cessation in Vietnam. METHODS In a cross-sectional survey, we interviewed 10,681 moth...
BACKGROUND AND OBJECTIVE Infant formula is supplemented with long-chain polyunsaturated fatty acids (LCPUFAs) because they are hypothesized to improve cognition. Several randomized controlled clinical trials have examined the effect of LCPUFA supplementation of infant formula on cognitive development. We conducted this meta-analysis to examine the efficacy of LCPUFA supplementation of infant fo...
A measurement of the top quark pair production ([Formula: see text]) cross section in proton-proton collisions at the centre-of-mass energy of 8[Formula: see text] is presented using data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.6[Formula: see text]. This analysis is performed in the [Formula: see text] decay channels with one isolated, high tr...
