We build a stellar-dynamical model of the Milky Way barred bulge and disk, using a newly implemented adaptive particle method. The underlying mass model has been previously shown to match the Galactic near-infrared surface brightness as well as gas-kinematic observations. Here we show that the new stellar-dynamical model also matches the observed stellar kinematics in several bulge fields, and ...

This paper compares the heuristic Global Search Techniques; Genetic Algorithm, Particle Swarm Optimization, Simulated Annealing, Generalized Pattern Search, genetic algorithm hybridized with Nelder–Mead and Generalized pattern search technique for tuning of fuzzy PID controller for Puma 560. Since the actual control is in joint space ,inverse kinematics is used to generate various joint angles ...

The age of the nearest particle pair is introduced as difference between current time and most recent when was formed. evolution equation for age-included distribution function derived. With assumption random destruction pairs, predicts exponential probability ages pairs. Particle-resolved numerical simulations with moving particles are performed to verify this prediction. then used derive part...

We present analytic results for the two tennis-court integral families relevant to $2\to2$ scattering processes involving one massive external particle and massless propagators in terms of Goncharov polylogarithms up transcendental weight six. also physical kinematics ladder-box family real-valued polylogarithmic functions, making our solutions well-suited phenomenological applications.

In this paper we propose an original approach to solve the Inverse Kinematics problem. Our framework is based on Sequential Monte Carlo Methods and has the advantage to avoid the classical pitfalls of numerical inversion methods since only direct calculations are required. The resulting algorithm accepts arbitrary constraints and exhibits linear complexity with respect to the number of degrees ...

Inverse kinematics is a fundamental problem in manipulator robotics: set of joint angles must be calculated so that the robot arm can manipulated to corresponding desired end effector position and orientation (also known as “pose”). Traditional solution techniques include analytical solvers, which provide closed-form expressions for positions functions end-effector pose. When inverse solvers ar...
