English

Subject field(s)
  • Collaboration with the FAO
  • Environmental Management
  • Commercial Fishing
OBS

In each catch, the fish are kept apart and are not released until the end of the last catch. This method leads to a depletion of the population number, which means that the number of fish caught in each catch will decrease. This makes it possible to make a linear regression between the number of fish caught in each catch(Y-axis) and accumulated number of fishes caught in the previous catches(X-axis). Like this, one can make a population estimate by calculating the intercept with the X-axis.

The local orbital reference system is defined at each point of the orbit by three unit vectors. These vectors are derived from the satellite position and velocity vectors: Vector L is colinear with position vector P (on the axis between the Earth’s centre and the satellite). It defines the yaw axis. Vector T is perpendicular to the orbital plane (vector L, vector V). It defines the pitch axis. Vector R completes the set of orthogonal axes. It lies in the plane defined by Vectors L and V and defines the roll axis. It does not coincide exactly with the velocity vector due to the eccentricity of the orbit.

CONT

Spacecraft axes. The three orthogonal axes of rotation: roll, pitch and yaw. If the spacecraft has a recognisable longitudinal axis or a specified forward direction of flight, the axes are analogous to those of an aircraft, where the roll axis is the longitudinal axis; the pitch axis is in the plane of the wings; and the yaw axis is the "vertical" axis, orthogonal to both the roll and pitch axes. The axes are mutually perpendicular, with an "origin" at the vehicle’s centre of mass. For a winged spacecraft such as a Space Shuttle, the similarity with an aircraft is obvious. For expendable launch vehicles the roll axis is the axis which is vertical at launch and the other axes are more-or-less arbitrarily assigned since the vehicle rotates about the roll axis in flight. ... The axes of a cylindrical spacecraft (e.g. Apollo, Suyuz, etc.) are similar to those of an ELV [Expendable Launch Vehicle] at launch, but one orbit assume the axis-definition of an aircraft (i.e. defined relative to the pilot’s seat). The axes of a satellite mirror those of an aircraft "flying along the orbital arc": the roll axis is aligned with the direction of travel; the yaw axis passes through the sub-satellite point; and the pitch axis is orthogonal to the other two. For a satellite in an equatorial orbit, the pitch axis is aligned approximately with the Earth’s spin axis. The pitch axis is also the spin axis for the spin-stabilised satellite.

OBS

In the compilation of engineering drawings the three orthogonal axes are often labelled in Cartesian fashion :x=roll, y=pitch, z=yaw. For the three-axis stabilised spacecraft, the x-axis and y-axis are otherwise known as the east-west and north-south axes, respectively; the z-axis passes through the sub-satellite point. This leads to the definition of the box-shaped satellite's faces as follows : the "plus-x face" faces east; the "minus-x face" faces west; +y faces south;-y faces north; +z is the Earth-pointing face; and-z is the "anti-Earth face.

If the centroidal axis is not colinear with the element x-axis, applied axial forces will cause a bending of the element. If the axis through the shear center is not colinear with the element x-axis, applied shear forces will cause torsional rotation of the element. The nodes should therefore be located at the desired point of application of the forces.

The description of the Station's flight attitude(orientation relative to the plane of its orbit) is referenced to local-vertical/local-horizontal(LVLH) axes that are fixed with respect to the Station's near-circular orbit(i. e., not to the physical Station). The LVLH origin is at the Station's center-of-mass; the z-axis points radially toward the Earth's center(or toward the nadir direction), the x-axis points along the orbital velocity vector(the ram direction, with wake being opposite), and the y-axis completes the right-handed triad. The flight attitude of the Station is then described using a second, Station-fixed, coordinate system whose orientation relative to LVLH is specified using the Eulerian angles of yaw, pitch and roll. Several Station-fixed coordination systems are defined. The most widely used is the Space Station Reference Coordinate System,... in thich the positive x-axis points along the axis of the U. S. lab away from the Zarya and Service Modules; the positive y-axis points starboard along the main truss, and positive z completes a right-handed coordinate system.

The intercept of a straight line, curve, or surface on an axis of coordinates is the distance from the origin to the point where the line, curve, or surface cuts the axis. The intercept on the axis of abscissas, or x-axis, is the x-intercept, and that on the axis of ordinates, or y-axis, the y-intercept.

Basically, charts are drawn according to the system of rectangular co-ordinates. Rectangular co-ordinates are based on two straight reference lines perpendicular to each other in a plane(...) The horizontal line is usually referred to as the X-axis, or the abscissa, whereas the vertical line is referred to as the Y-axis, or the ordinate. The two lines divide the plane into four parts called quadrants(...) The point of intersection of the two lines is called the origin, or zero point. Scales are labeled along the two axes, beginning at the point of origin. The abscissas(...) to the right of the origin are conventionally designated as positive, whereas those to the left of the origin are negative. The ordinates(...) above the origin are positive, and those below the origin are negative. Any point on the plane may refer to two values according to the two scales.

Les points sont repérés par rapport à deux axes, l'un horizontal, dit des abscisses, l'autre vertical, dit des ordonnées. Le point 0 où ils se coupent est l'origine à partir de laquelle on compte les grandeurs positivement vers le haut et vers la droite, négativement vers le bas et vers la gauche.
