Data type obtained include attitude (Strike, dip and dip direction) of the fracture plane as well as nature of fracture surface, cross-cutting relations, mean separation between the fractures, bedding orientation and relationship and others which may be of use in determining the relative age relationships between the fractures and dividing them into fracture sets and systems.
Since the attitude motion is essential in non-Euclidean space, thus, unlike the existing designs which describe the delayed relative attitude via linear algorithm, we treat the attitude error and the local relative attitude on the nonlinear manifold-Lie group, and attempt to obtain coupling attitude information by the natural quaternion multiplication.
In order to obtain the attitude of the satellite with desired accuracy an extended Kalman filter (EKF) for satellite's angular motion parameter estimation is designed.
In maritime dynamic positions systems, high-performance inertial sensors are employed to obtain continues attitude information; such systems are very expensive, and they are not spread on all common ships.
Each spacecraft carries an Absolute Scalar Magnetometer (ASM) for measuring Earth's magnetic field intensity, a Vector Fluxgate Magnetometer (VFM) measuring the direction and strength of the magnetic field, and a three-head Star TRacker (STR) mounted close to the VFM to obtain the attitude needed to transform the vector readings to an Earth-fixed coordinate frame.
Each of the three satellites carries an Absolute Scalar Magnetometer (ASM) measuring Earth's magnetic field intensity, a Vector Fluxgate Magnetometer (VFM) measuring the magnetic vector components and a three-head Star TRacker (STR) mounted close to the VFM to obtain the attitude needed to transform the vector measurements of the VFM magnetometer to a known coordinate frame.
These discussions enabled the youths to validate the information they received during class, to consolidate what they learned during the prevention sessions, and favour the dissemination of this knowledge beyond the scope of the academic environment.The results obtained regarding youths" attitudes and knowledge demonstrate that attitude modification takes place progressively.
The Attitudes towards Children who Self-harm Questionnaire (ACS) was used to obtain participants' attitudes towards self-harm.
As a result, through the attitude obtained via the IMU, the flow of the pumps is adapted automatically to any orientation that the probe has, in order to fulfill the motion in the wanted direction.
