In view of their physics goals, future neutrino factories from muon decay aim at an overall flux precision of O(1%) or better. We analytically study the QED radiative corrections to the neutrino differential distributions from muon decay. Kinematic uncertainties due to the divergence of the muon beam are considered as well. The resulting corrections to the neutrino flux turn out to be of order ...

Kinodynamic planning attempts to solve a robot motion problem subject to simultaneous kinematic and dynamics constraints. In the general problem, given a robot system, we must nd a minimal-time trajectory that goes from a start position and velocity to a goal position and velocity while avoiding obstacles by a safety margin and respecting constraints on velocity and acceleration. We consider th...

We identify and resum corrections associated with the kinematic recoil of the hard scattering against soft-gluon emission in single-particle inclusive cross sections. The method avoids double counting and conserves the flow of partonic energy. It reproduces threshold resummation for high-pT single-particle cross sections, when recoil is neglected, and QT resummation at low QT , when higher-orde...

Humans, including children [7], can describe mechanisms using whatever knowledge and information they have . That is they often switch between dynamic and kinematic descriptions depending on th e information available to them . Furthermore, they seem to perform such reasonings subconsciously . For instance, they can describe how meshed gear trains work by just addressing how rotationa l velocit...

In this paper we derive and analyze a discontinuous stabilizing feedback for a Lie algebraic generalization of a class of kinematic nonholonomic systems introduced by Brockett. The algorithm involves discrete switching between isospectral and norm-decreasing ows. We include a rigorous analysis of the convergence. 1. Introduction. In this paper we present a stabilization algorithm for a Lie

this work intends to deal with the optimal kinematic synthesis problem of tricept parallel manipulator. observing that cuboid workspaces are desirable for most machines, we use the concept of effective inscribed cuboid workspace, which reflects requirements on the workspace shape, volume and quality, simultaneously. the effectiveness of a workspace is characterized by the dexterity of the manip...

Since a parallel structure is a closed kinematics chain, all legs are connected from the origin of the tool point by a parallel connection. This connection allows a higher precision and a higher velocity. Parallel kinematic manipulators have better performance compared to serial kinematic manipulators in terms of a high degree of accuracy, high speeds or accelerations and high stiffness. Theref...

We consider the robot motion planning problem in the presence of non-integrable kinematic constraints, known as non-holonomic constraints. Car-like non-holonomic mobile robots are used for solving this problem, and several implemented planners are discussed. We claim that the randomized methods are more capable of efficiently solving many challenging, high-dimensional problems. Results with ran...
