Abstract As the second stage of CEPC-SPPC project, SPPC (Super Proton-Proton Collider) aims at exploring new physics beyond Standard Model. The key design goal for accelerator complex is to reach 75 TeV in center mass energy with a circumference 100 km collider and an injector chain four accelerators cascade support collider. important part conceptual study, longitudinal beam dynamics was studi...

Distributed memorymachines have been around for quite a long time, but, in spite of their excellent performance/price ratio, they are not widely used for scientiic applications. The main reason for that setback is that no compiler is available for these applications, usually written in Fortran, and for this machine architecture. We developped in PUMA Esprit Project a prototype compiler, taking ...

The quality of video transmitted by mobile ad hoc networks (MANETs) can be influenced by several factors, including protocol layers; parameter settings of each protocol. In this paper, we are concerned with understanding the functional relationship between these influential factors and objective video quality in MANETs. We illustrate a systematic statistical design of experiments (DOE) strategy...

This paper presents a new concept to implement a tunable filter metamaterial with dual negative refraction composed of ferrite slabs and metallic resonators, including split-ring resonators (SRR), and short wire pairs. The ferrite slabs under an applied magnetics bias provide one magnetic resonance frequency band and the metallic resonators provide another one. The continuous wires within the m...

comments on related versions. Abstract We provide a general model for comparing stepwise and lumpy investments, considering stage specific volatilities, drifts and possibility of project failure. Stepwise investments allow for interim project value realizations, instead of considering only a final project value as in sequential investments. We conceive of an environment in which stepwise invest...
