Kinematics and Dynamics of Messier 31 1
We present a new deep 21-cm survey of the Andromeda galaxy, based on high resolution observations performed with the Synthesis Telescope and the 26-m antenna at DRAO. The Hi distribution and kinematics of the disc are analyzed and basic dynamical properties are given. The rotation curve is measured out to 38 kpc, showing a nuclear peak at 340 km s, a dip at 202 km s around 4 kpc, two distinct f...
متن کاملMathematical Dynamics, Kinematics Modeling and PID Equation Controller Of QuadCopter
Abstract Quadcopter is the Unmanned Aerial Vehicle that can vertical tack off and landing. its useful platform for many applications in Commercial, civil or military . In this article ,we present the Dynamics and Kinematics model of quadcopter and the effect of forces by introducing two frames on the ground and it’s body, also we design and implement the PID controller t...
متن کاملH α Kinematics of the SINGS Nearby Galaxies Survey . I ⋆
This is the first part of an Hα kinematics follow-up survey of the SINGS sample. The data for 28 galaxies are presented. The observations were done on three different telescopes with FaNTOmM, an integral field photon counting spectrometer, installed in the respective focal reducer of each telescope. The data reduction was done through a newly built pipeline with the aim of producing the most ho...
متن کاملKinematics and Dynamics of two Cooperating Robots in Spatial Moving of an Object
The kinematics and dynamics of two industrial cooperating robots are presented in this paper. The NOC (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. The joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. To this end, minimizing the cr...
