Harmonics of the mains frequency (50 Hz) have been systematically observed in transverse beam spectrum Large Hadron Collider (LHC) since start its operation form dipolar excitations. In presence strong nonlinearities such as beam-beam interactions, many these 50 Hz harmonics reside vicinity betatron tune they can increase diffusion particles distribution, leading to proton losses and eventually...

In this paper, a methodology for self-calibrating a multi-beam laser tracking measurement system with planar constraints is proposed. A model for the multiple-beam laser tracking system is derived. Through error analysis it is shown that using even rough angular measurement of the gimbal joint positions may improve the overall system calibration results. Parameter observability issues are studi...

In this article, we propose a new particle filtering scheme, called a switching particle filter, which allows robust and accurate visual tracking under typical circumstances of real-time visual tracking. This scheme switches two complementary sampling algorithms, Condensation and Auxiliary Particle Filter, in an on-line fashion based on the confidence of the filtered state of the visual target....

Visual object tracking is the active area of research in the computer vision. Various techniques have being developed for the object tracking .Particle filter deals with the tracking of the objects having non linear motion .Particle filter has been used in for various fields and application efficiently. Proposed Technique is based on combination of kalman filter, mean shift and particle filter....

The treatment of moving tumors with a scanned ion beam is challenging due to interplay effects and changing beam range. We propose multigating, as a method for 4D-treatment optimization and delivery. In 3D beam tracking, tracking vectors are added during delivery to beam spot positions based on the detected motion phase. This has the disadvantage of dose errors in case of complex motion pattern...
