Abstract Wind load is commonly regarded as the dominant lateral in designing tall buildings. Thus, it of necessity to investigate parameters affecting wind-induced loads. One these exterior shape building, which using its aerodynamic modifications, wind loads, can be decreased. In this research, different buildings with trilateral cross-section constructed via polynomial parameterization method...

BACKGROUND Medial elbow distraction during pitching as the primary mechanism contributing to adaptations in ulnar collateral ligament (UCL) appearance during magnetic resonance imaging (MRI) evaluation has not been established. HYPOTHESIS Uninjured high school-aged pitchers with unilateral adaptations of the UCL exhibit a higher peak internal elbow adduction moment than those without UCL adap...

This paper develops an adaptive elastic-net GMM estimator with many possibly invalid moment conditions. We allow for the number of structural parameters (p0) as well as the number of moment conditions increasing with the sample size (n). The new estimator conducts simultaneous model and moment selection. We estimate the structural parameters along with parameters associated with the invalid mom...

The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...

With recent advancements of computers and the advent of a search and optimization tool such as the genetic algorithm (GA), the ability to manipulate numerous aircraft design parameters in reasonable amount of time becomes feasible. It is from this standpoint that when one examines the aircraft design process, that is, the lengthy time and effort spent creating and integrating aerodynamics codes...

We study the problem of parametric estimation for continuously observed stochastic processes driven by additive small fractional Brownian motion with Hurst index H∈(0,1)/{12}. Under some assumptions on drift coefficient, we obtain asymptotic normality and moment convergence maximum likelihood estimator parameter when a dispersion coefficient ε→0.

A full-wave moment-method technique developed for the analysis of quasi-optical (QO) systems is used to model finite grid structures in a lens system. This technique incorporates an electric-field dyadic Green’s function for a grid centered between two lenses. This is derived by separately considering paraxial and nonparaxial fields. Results for the driving point reflection coefficient of a 3 3...

The distance correlation coefficient – based on the product-moment approach – is one method by which to explore the relationship between variables. The Bayesian approach is a powerful tool to determine statistical inferences with credible intervals. Prior information about the relationship between BP and Serum cholesterol was applied to formulate the distance correlation between the two variabl...

This article discusses the peculiarities of self-organization behavior and formation of dissipative structures during friction of antifriction alloys for slide bearings against a steel counterbody. It shows that during self-organization, the moment of friction in a tribosystem may be decreasing with the load growth and in the bifurcations of the coefficient of friction with respect to load. Sel...

This paper presents a procedure that constructs a Markovian Arrival Process (MAP) based on the mean, the squared coefficient of variation and the lag-1 autocorrelation of the inter-arrival times. This method always provides a valid MAP without posing any restrictions on the three input parameters. Besides matching these three parameters, it is possible to match the third moment of the inter-arr...
