LH frame is obtained from the ECEF frame through the following rotations: [mathematical expression not reproducible].
Early childhood education for sustainability (ECEfS) has been nationally and globally recognised as having the potential to nurture caring, capable and responsible citizens, by providing children with knowledge about sustainability problems, a voice in decision-making about these issues and the skills to do something about it (Davis & Elliott, 2014; Pramling Samuelsson & Kaga, 2008).
where k represents the satellite number (k = 1,2,...,[N.sub.sat]), [lambda] represents the wavelength of transmitted satellite signal, ([v.sub.MS,x], [v.sub.MS,y], [v.sub.MS,z] ) and ([v.sub.sat,x],[v.sub.sat,y],[v.sub.sat,z]) are respectively the user and the satellite ECEF velocities, [u.sub.k] = [[u.sub.x,k],[u.sub.y,k],[u.sub.z,k]] represents the direction unit vector from the satellite to the receiver, and cdt represents the receiver clock drift.
where xyz stand for the coordinates in WGS84, and blh stand for the coordinates in ECEF.
Enhancing customer experience through business process improvement: An application of the enhanced customer experience framework (ECEF).
The user coordinates are in the rotating Earth-fixed frame (ECEF).
Obtainment of Satellites' Coordinates in ECEF. With the almanac files supplied by the website of navcen.uscg.gov and actually broadcasted by GPS satellites, the real-time coordinate of all satellites in orbit are calculated; then the coarse precision satellites' tracks can be obtained.
The World Geodetic System 1984 (WGS84) is used for the geodetic reference and Earth-centred Earth-fixed (ECEF) is the Cartesian coordinate frame of reference used in GPS.
This section explains the detailed DDM simulation process which includes three steps: 1) determine the location of the glistening zone surrounding the Specular Point (SP) in the Earth-Centered, Earth-Fixed (ECEF) coordinate System [10].
The nominal position of the observation site is (-1507932.6167, 6195587.6757, 148897.9990) in the earth-centered, earth-fixed (ECEF) Cartesian coordinate system [13].
The position and velocity components of GLONASS satellites, taken from the navigation message, are re-computed from ECEF (Earth Centered, Earth Fixed) Greenwich coordinate system (PZ-90.02) to an absolute coordinate system.
Por lo tanto, los objetivos planteados en este estudio fueron: a) desarrollar y validar la Escala de Comunicacion en Educacion Fisica (ECEF) y la Escala de Evitacion de Barreras de Comunicacion en Educacion Fisica (EEBCEF) enfocadas a la medida de la comunicacion en Educacion Fisica, b) conocer, a traves de un analisis descriptivo y correlacional, las relaciones entre la comunicacion verbal, comunicacion no verbal, las estrategias de evitacion de las barreras de comunicacion utilizadas por el docente y la motivacion intrinseca del estudiante y c) comprobar mediante regresion lineal la prediccion de la comunicacion verbal, no verbal y las estrategias de evitacion de barreras sobre la motivacion intrinseca.
