We discuss the use of the Crystal Ball detector for the study of e+eannihilations near charm threshold: at the $(3097), $'(3685), $"(3770) and in the "continuum" 37701&<4500 MeV. This paper will concentrate on the special techniques available to the Crystal Ball which allow measurement of inclusive y, noand n cross sections. Preliminary results for these processes at particular center of mass e...

The first part aimed at initiating a European database of empirical critical loads of nitrogen. Empirical critical loads are based on effects of (elevated) nitrogen deposition on ecosystems. A compilation of all relevant studies led to well established ranges (UBA, 2004). The value for the empirical critical load can be picked from this range, depending on other local factors, such as temperatu...

We present an immersed boundary method for mass transfer across permeable deformable moving interfaces interacting with the surrounding fluids. One of the key features of our method is the introduction of the mass flux as an independent variable, governed by a non-standard vector transport equation. The flux equation, coupled with the mass transport and the fluid flow equations, allows for a na...

We present a distributed spin-down algorithm for conserving energy in an object-based storage device (OSD) cluster. It differs from traditional spin-down algorithms in that it is cooperative—the decision to spin-down an OSD considers not only its own internal state, but also the state of the other OSDs. Each OSD executes an instance of the spin-down algorithm and adapts to the overall workload....

The performance of streaming media servers has been limited due to the dual requirements of high throughput and low memory use. Although disk throughput has been enjoying a 40% annual increase, slower improvements in disk access times necessitate the use of large DRAM buffers to improve the overall streaming throughput. MEMS-based storage is an exciting new technology that promises to bridge th...

This presentation aims to describe a method to use a Object-based Storage Device (OSD) Cloud Storage system based on p2p network distributed files as a block level storage system with iSCSI protocol. This coupling of designs allows the user to take advantage of the replication, reliability, scalability and large storage capacity of a Cloud Computing provider without the need for specific or ded...
