The phrase "at a cross section" is correct and usable in written English.
It can be used when discussing a specific point of intersection or analysis within a broader context, often in fields like science, engineering, or social studies.
Example: "The study focuses on the community's needs at a cross section of socioeconomic factors."
Alternatives: "at an intersection" or "at a junction".
In contrast to the classical time-to-collision value, measured at a cross section, the improved safety indicators use vehicle trajectories collected over a specific time horizon for a certain roadway segment to calculate the overall safety indicator value.
The moving traverse method is the most frequently used technique to measure the average air velocity at a cross section.
By such induction of the longitudinal forces at a cross section, the internal couple C o and T o calculated from the conventional beam theory due to the bending moment is redistributed to meet the equilibrium condition over the section.
Measurement results demonstrate that differences in the measured average air velocities between the moving traverse method and the fixed-point traverse method exist at a cross section where the air velocity spans a wide range.
It was found out that the mounted location of a velocity sensor plays an important role in the sensor readings at a cross section, due to the irregular velocity distribution at the plane where the sensor is mounted.
When the laminar flow passes through the curved channels/ducts, the centrifugal force pushes the fluid from the center of the channel when the bulk fluid flows with high velocity to the outer side, while the fluid at the outer wall is pressed either upwards or downwards, thus producing two vortices to fill the entire channel at a cross section along the downstream [6].
Hence, both ERGM and SAOM require a network composed of binary ties captured at one point in time as a cross section or at a limited number of discrete time points.
At right, a cross section of Monopleura salazari.
Like growth rings on trees, the players on Sunday's leader board at Augusta National revealed a cross section of age.
If you were to slice a knife through the earth and look at the cut, a cross section would generally show bands of solid rock bent over like a bell or bent up like a bowl.
(A) Morphology of the untreated E. coli cell at 0 h (a); cross section of the untreated E. coli cell after 12 h (b).
