Abstract: A control scheme is developed to address the attitude tracking problem of a rigid spacecraft. A sufficient condition to accommodate actuator misalignment is presented. The controller ...

MPI-Rockstar is a massively parallel halo finder based on the Rockstar phase-space temporal halo finder code (Behroozi et al., 2013), which is one of the most extensively used halo finding codes.

This contribution is part of the special series of Inaugural Articles by members of the National Academy of Sciences elected in 2015. Gravitational radiation provides a probe of unprecedented power ...

This paper presents a novel theoretical framework that bridges electromagnetic and gravitational fields through generalized gauge transformations. The author demonstrates how curvature tensor ...

ctplanet provides several functions and example scripts for generating crustal thickness maps of a planet from gravity and topography data, and the calculation of hydrostatic relief along density ...

Abstract: A rapid recurrent neural network (RNN)-based physical feasibility test algorithm for base parameters during the identification process of a robot dynamic model is proposed in this paper.

New oblique impact methods for evaluating head injury mitigation effects of helmets are emerging, which mandate measuring both translational and rotational kinematics of the headform. These methods ...

Quite a few Olympic events involve flipping and twisting, including gymnastics, diving, and trampoline. You might ask, "What is the difference between a flip and a twist?" I am going to give my ...

One route to resolving this enigma may be provided by studies of planetary rotation 13,14 that revise the standard equilibrium rotational theory 8,9 to argue that a rotating system can retain ...

Diffusion tensor magnetic resonance imaging (DTI) is a relatively new technology that is popular for imaging the white matter of the brain. This article provides a basic and broad overview of DTI to ...
