Software Process Improvement requires significant effort related not only to the identification of relevant issues and providing an adequate response them, but also implementation adoption changes. Best practices provide recommendations software teams on how address identified objectives in practice, based aggregated experience knowledge. In paper, we present GEANT observations from process ado...

The discovery potential of Standard Model Higgs searches at the LHC at 14 TeV center-of-mass energy is reviewed. Decay channels such as H → γγ, H → ZZ → 4l, H → WW ⋆ and H → ττ are considered. Results are based on the most recent full GEANT-based simulations performed by the ATLAS and CMS experiments.

This paper analyzes the performance of two implementations of J-Flow, the flow measurement tool deployed on most Juniper routers. Our work relies on both controlled experiments and analysis of traces collected at Abilene and GEANT, which provide most of the flow traces used in the research community. We uncover two measurement artifacts in J-Flow traces: a periodic pattern and measurement gaps....

Real-time track tracking in high energy physics experiments at colliders running luminosity is very challenging for trigger systems. To perform pattern-recognition and fitting online system, the artificial Retina algorithm has been introduced field. can be implemented state of art FPGA devices. Our developments use an iterative way to identify barrel-shape tracker embedded a magnetic field with...

In the proposed E-166 experiment at SLAC, 50 GeV electrons pass through a helical undulator, and produce circularly polarized photons, which interact with a tungsten target and generate longitudinally polarized positrons. The background is an important issue for an experiment under consideration. To address this issue, simulations were performed with the code GEANT3 to model the production of s...

The observation of exotic stable massive particles (SMPs) with electric, magnetic or colour charge (or combinations thereof) would be of fundamental significance. Searches are therefore routinely made for SMPs bound in matter, and for SMPs at cosmic ray and collider experiments [1, 2, 3, 4]. Furthermore, SMPs with masses at the TeV scale are anticipated in a number of beyond-the-Standard-Model ...

We have made a basic study of a polarized positron source for the next generation linear collider, JLC[1][2]. This is based on a new idea that polarized positrons are pair-created from polarized γ -rays produced through Compton scattering of circularly polarized laser lights o relativistic electron beams[3][4]. Since a pulse duration of γ -rays thus produced is extremely short i.e. 20 psec, the...

Geant4 [ref G1, ref G2] is a simulation toolkit written in C++ using Object-Oriented principles, and re-engineered from the Fortran-based Geant3. As of Geant 3.21, the Fortran code is officially no longer supported. Geant4 is developed and maintained by a world-wide collaboration including centers at CERN, SLAC, FNAL, KEK and others. The code is available without cost at http://geant4.cern.ch, ...

This paper describes an efficient way to implement managed bandwidth services. The proposed solution is based on MPLS technology and especially with the creation of virtual private networks. The virtual private networks will be layer 3 VPNs (IP VPNs) and are described all the mechanisms and the MPLS features that are necessary for the MBS service implementation. The paper also describes how the...
