This paper presents an on-going research to develop the Inter-Cloud Architecture, which addresses the architectural problems in multi-provider multi-domain heterogeneous cloud based applications integration and interoperability, including integration and interoperability with legacy infrastructure services. Cloud technologies are evolving into a common way to virtualize infrastructure services and to offer on-demand service provisioning. In this way, they add physical/hardware platform independency and mobility to the existing distributed computing and networking technologies. The paper uses existing standards in Cloud Computing, in particular the recently published NIST Cloud Computing Reference Architecture (CCRA) as the basis for the Inter-Cloud architecture. The proposed Inter-Cloud Architecture defines three complimentary componen...

The mean life of the 0.119-Mev state of N16 has been measured and is found to be 7.83(1±0.04)×10^-5 second. This state was produced by means of the N15(d, p)N16 reaction with deuterons having a laboratory energy of 1.76 Mev. The experiment involved periodically directing the deuteron beam onto and then away from the target. The lifetime was determined by measuring the decay rate of the 0.119-Mev γ-ray activity during the periods when the beam was off the target.
Angular distributions have been measured for three groups of protons from the O18(d, p)O19 reaction, those leaving O19 in its states at 0, 0.096, and 1.47 Mev. Deuteron energies of 1.74 and 2.50 Mev in the laboratory system were used. The distributions of protons leaving O19 in its ground state and in its 1.47-Mev state are characteristic of stripping and indicate the formation of the ground state by an l=2 neutron and of the 1.47-Mev state by an l=0 neutron. However, the distribution of protons leaving O19 in its 0.096-Mev state does not lend itself to a stripping interpretation. It has been found that the γ decay of the 1.47-Mev state of O19, following the formation of this state in the O18(d, p)O19 reaction, proceeds mostly to the 0.096-Mev state. The mean life of the 0.096-Mev state has been measured by observing the decay in f...
We present a theoretical analysis of phase separation in the presence of a spatially periodic forcing of wavenumber q traveling with a velocity v. By an analytical and numerical study of a suitably generalized 2d-Cahn-Hilliard model we find as a function of the forcing amplitude and the velocity three different regimes of phase separation. For a sufficiently large forcing amplitude a spatially periodic phase separation of the forcing wavenumber takes place, which is dragged by the forcing with some phase delay. These locked solutions are only stable in a subrange of their existence and beyond their existence range the solutions are dragged irregularly during the initial transient period and otherwise rather regular. In the range of unstable locked solutions a coarsening dynamics similar to the unforced case takes place. For small and...
