The Hallade method, devised by Frenchman Emile Hallade, is a method used in track geometry for surveying, designing and setting out curves in railway track. [1] It involves measuring the offset of a string line from the outside of a curve at the central point of a chord. In reality, string is too thick to provide a clear reading and breaks ...
Rankine's method or tangential angle method is an angular technique for laying out circular curves by a combination of chaining and angles at circumference, fully exploiting the theodolite and making a substantial improvement in accuracy and productivity over existing methods. This method requires access to only one road/path of communication ...
As an example, a curve with an arc length of 600 units that has an overall sweep of 6 degrees is a 1-degree curve: For every 100 feet of arc, the bearing changes by 1 degree. The radius of such a curve is 5729.57795. If the chord definition is used, each 100-unit chord length will sweep 1 degree with a radius of 5729.651 units, and the chord of ...
Gunter's chain (also known as Gunter's measurement) is a distance-measuring device used for surveying.It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626).
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

Mills had 37 tackles and 7 1/2 sacks this season and anchored the interior line while All-American Howard Cross II missed the final three regular season games with a high ankle sprain. Cross ...
1 c. chicken broth. 1/4 c. fresh lemon juice. 5. garlic cloves, smashed. Directions. Preheat the oven to 450°F. In a medium measuring cup, whisk together the butter, oregano, salt, and pepper.
There are three forms of least squares adjustment: parametric, conditional, and combined: In parametric adjustment, one can find an observation equation h(X) = Y relating observations Y explicitly in terms of parameters X (leading to the A-model below).
