In this paper, a novel framework for visual tracking of human body parts is introduced. The presented approach demonstrates the feasibility of recovering human poses with data from a single uncalibrated camera using a limb tracking system based on a 2D articulated model. It is constrained only by biomechanical knowledge about human bipedal motion, instead on relying on constraints linked to a s...

geant4 is an open source simulation toolkit based on c++, which its advantages progressively lead to applications in research domains especially modeling the biological effects of ionizing radiation at the sub-cellular scale. however, it was shown that geant4 does not give a reasonable result in the prediction of antiproton dose especially in bragg peak. one of the reasons could be lack of a re...

An investigation of the beam-beam interaction as a function of transverse separation of colliding proton and antiproton bunches is presented. A mathematical model describing resonant excitation of separated beams is examined. Beam-beam experiments in the Fermilab collider measure beam-beam resonant excitation ~particle losses! at different transverse beam separations in the storage ring. The ex...

In a millimeter wave (mmWave) communication system with transmit/receive (Tx/Rx) beamforming antennas, small variation in device behavior or an environmental change can destroy beam alignment, resulting in power loss in the received signal. In this situation, the beam-tracking technique purely based on the received signal is not effective because both behavioral changes (rotation, displacement)...

The beam delivery system of the carbon ion therapy at GSI has been modified to perform beam tracking [1,2]. Beam tracking is achieved by monitoring the target motion and by adapting the pencil beam in lateral (magnetically) and in longitudinal direction (motorized wedge absorbers). The updated integrated system was experimentally tested for left-right target motion with depth changes that were ...

We describe results from a beam test of a telescope consisting of three planes of single-crystal, diamond pixel detectors. This telescope is a prototype for a small-angle luminosity monitor, the Pixel Luminosity Telescope (PLT), for CMS. We recorded the pixel addresses and pulse heights of all pixels over threshold as well as the fast-or signals from all three telescope planes. We present resul...

Three-particle correlations have been measured for identified π from central 158 A GeV Pb+Pb collisions by the WA98 experiment at CERN. A substantial contribution of the genuine three-body correlation has been found as expected for a mainly chaotic and symmetric source. In nuclear and particle physics, the study of Bose-Einstein correlations between identical particles is widely used. It is an ...

A reference tracking telescope consisting of three stations based on double-sided silicon microstrip detectors has been constructed and tested in a 2 GeV proton beam experiment at GSI. This proof-of-principle device designed for charged particle track measurement with high spatial resolution closely integrates silicon sensors with self-triggering front-end electronics. Each station features the...
