Civil engineering Relationship between mass and modal frequency of a concrete girder bridge UTAH STATE UNIVERSITY Marvin W. HallingPaul J. Barr DeanMichael WIn April of 2008, the Federal Highway Administration (FHWA) launched the Long Term Bridge Performance (LTBP) program. The program was ...
Results After adjusting for age, ethnic background, subjective socioeconomic status, frequency of breakfast consumption, and physical activity, heavy social media use (>2 hours/day) was associated with higher BMI z-scores among males (β=0.323, 95% CI: 0.094; 0.551) than among females (β=...
magnitudes (p< 0.05) were found for all upper and lower extremity lean mass and functional values. No relationship was apparent between lean mass and functional asymmetry magnitudes (p-value range = 0.131–0.889). Despite finding perfect consistency in asymmetry direction (k-value = 1.00) for th...
In general, the integral form of a balance equation describes the relationship between certain quantities within a finite volume and across its bounding surface. Differential balance equations, on the other hand, express the relationships for the derivatives of these quantities at a given point of ...
We explored whether BMI aged 20 years modified the relationship between subsequent weight changes to BMI at cohort entry and breast cancers, stratified at the 75th percentile of BMI aged 20 years (23.4 kg/m2).A BMI ≥23.4 kg/m2...
We examine the relationship between the high-frequency (425 MHz) type II radio burst and the associated white-light coronal mass ejection (CME) that occurr... KS Cho,N Gopalswamy,RY Kwon,... - 《Astrophysical Journal》 被引量: 16发表: 2013年 A Type II Radio Burst without a Coronal Ma...
Using the Yale Rotation and Evolution Code (YREC), a grid of stellar models has been constructed. Meanwhile, the frequency of maximum oscillations' power νand the large frequency separation Δν are calculated using the scaling relations. For the stars, the masses of which are from 0.8 M to...
For multivariable-adjusted analyses, the following additional adjustment variables were used: income status (first [low income], second, third and fourth quartile), smoking status (current smoker, former smoker, never smoker, and missing information [n = 357,470]), frequency of alcohol use ...
The EMG spectral median frequency (MF) decrease over time was used for the assessment of back and hip extensor fatigability. In experiment 1, the rate of change in paraspinal MF was greater in men than in women, indicating greater paraspinal fatigability in men. Multiple regression analysis ...
8. The modal equivalent MDOF system has the distinction and advantage that it can characterize well the one-dimensional ground properties, under shaking, such as natural frequency and hysteretic damping. Comparisons of the amplification function of the modal equivalent MDOF system with the theoretical ...
