The ‘smarter’ approach to processing described in this paper is limited to the benefi ts of a more effi cient high pressure grinding roll (HPGR) circuit over a traditional semi-autogenous grinding (SAG) comminution circuit. The effi ciency challenge described concerns comminution circuit designs that are relatively risk averse and compliment current mainstream engineering practice. The HPGR eff...

In recent years, as the demand for low energy and high performance computing has steadily increased, heterogeneous computing has emerged as an important and promising solution. Because most w orkloads can typically run most eff iciently on certain types of cores, mapping tasks on the best available resources can not only save energy but also deliver high performance. How ever, optimal task sche...

This paper reviews experience with two programs sponsored by the US Environmental Protection Agency* the Green Lights and Energy Star O$ce Products programs* that promote the adoption of energy-e$cient technologies through voluntary agreements with private sector "rms. The evidence suggests that Green Lights has induced "rms to make investments in cost-saving lighting systems that "rms failed t...

The BQ-CHECK phantom (PTW Freiburg, Germany) has been designed to be used with a 2D ion chamber array to facilitate the quality assurance (QA) of electron and photon beam qualities (BQ). The BQ-CHECK phantom has three wedges covering the diagonal axes of the beam: two opposed aluminum wedges used to measure electron energy and a single copper wedge used to measure photon energy. The purpose of ...

Measurements of the Nusselt number Nu and of a Reynolds number Re(eff) for Rayleigh-Bénard convection (RBC) over the Rayleigh-number range 10(12)≲Ra≲10(15) and for Prandtl numbers Pr near 0.8 are presented. The aspect ratio Γ≡D/L of a cylindrical sample was 0.50. For Ra≲10(13) the data yielded Nu∝Ra(γ(eff)) with γ(eff)≃0.31 and Re(eff)∝Ra(ζ(eff)) with ζ(eff)≃0.43, consistent with classical turb...

Photon interaction effective atomic number (Z eff ) for partial as well as total photon interaction processes has been computed using logarithmic interpolation method for seven different concretes viz. (i) Ordinary, (ii) Hematite Serpentine, (iii) Ilmenite Limonite, (iv) Basalt magnetite, (v) Ilmenite, (vi) Steel scrap and (vii) Steel magnetite concrete in the wide energy range from 10.0 keV to...

traditional dea models deal with measurements of relative eciency ofdmus regarding multiple - inputs vs. multiple-outputs. one of the drawbacksof these model is the neglect of intermediate products or linkong activities. af-ter pointing out needs for inclusion of them to dea models. we propose hybridmodel that can deal with intermediate products formally using this model wecan evaluate divisio...

Many studies in literature have shown that energy-aware routing (EAR) can significantly reduce energy consumption for backbone networks. Also, as an arising concern in networking research area, the protocol-independent tra c redundancy elimination (RE) technique helps to reduce (a.k.a compress) tra c load on backbone network. Motivation from a formulation perspective, we first present an extend...
