Abstract: We introduce a new class of attitude control laws for rotational systems, which generalizes the use of the Euler axis–angle representation beyond quaternion-based formulations. Using basic ...

A new analysis argues that the Milky Way’s central black hole, Sagittarius A*, spins at maximum velocity with its axis aimed almost directly at Earth. The result emerges from a machine learning read ...

I have a code that conducts homogeneous transformation with 4X4 homogeneous transformation matrix on SMPL mesh vertices to convert it from World coordinate to Camera coordinate. I can successfully ...

Off-axis parabolic mirrors (OAP Mirrors) provide ideal focus points for colliding light beams and are frequently utilized in modern optical systems to meet increasingly severe performance criteria.

This valuable work presents the latest version of CTFFIND, which is the most popular software for determination of the contrast transfer function (CTF) in cryo-electron microscopy. CTFFIND5 estimates ...

%the axis angle representation of that R such that exp((w)^(theta))=R. %Where w is the unit axis of rotation (||w||=1) and theta is the angle of %rotation (theta will be between 0 and pi). %this ...
