By further analyzing the curvilinear mathematical models themselves, he determined not only how a success rate changes with age but also how the "rate of change" in a success rate changes with age.
UPML equations in an orthogonal curvilinear coordinate system are as follows:
Adjusting for the neighbourhood-level socioeconomic status only, participants residing in curvilinear neighbourhoods, on average, had significantly (p < 0.05) larger waist circumference ([beta] = 4.09; 95% CI 1.68, 6.50 cm) than participants from grid neighbourhoods (Table 2).
Children residing in grid-pattern and curvilinear neighbourhoods consistently accumulated higher MVPA and lower SB than children living in fractured-grid pattern neighbourhoods.
Cylindrical curvilinear semi-rings in a cylindrically-shaped cyclone are arranged in the descending order of radii and due to such arrangement the highest volume is in channel 2 resulting in velocity change of up to 18.9-21.2%, compared to velocity recorded in channel 1.
fragilis has sigmoid-shaped anterior spines (Figure 5) whereas its dorsal and lateral spines are curvilinear. These anterior spines, along with the anterolateral spines, appear to be mostly responsible for digging forward.
Four types of rock art have been identified on Uneapa: cupules, curvilinear, three-dimensional and rectilinear.
The association between education and divorce was also curvilinear, as the and highest educated women shared the lowest rate of first divorce, with 14.4 and 14.2 per 1,000, respectively.
Even though the construct of ACAP has been studied widely during the past two decades (Easterby-Smith et al., 2008; Lane et al., 2006), there have not been any findings yet on curvilinear relationships between ACAP and performance.
Some areas addressed are numerical studies in axial and centrifugal turbomachines, the application of boundary layer techniques to turbomachinery, blade aerodynamic parameterization and optimization methods, and governing equations expressed in non-orthogonal curvilinear coordinates for calculating 3D viscous fluid flow in turbomachinery.
The sensors can operate in a curved position to detect curvilinear measurements at a minimum radius of 200 mm.
