Discussing aspects of AOP

Abstract: Aspect-oriented programming is a new evolution in the line of technology for separation of concerns technology that allows design and code to be structured to reflect the way developers want to think about the system. AOP builds on existing technologies and provides additional mechanisms that make it possible to affect the implementation of systems in a crosscutting way.

Microgrid stability: Classification and a review

Abstract: Microgrid is becoming an attractive concept to meet the increasing demands for energy and deal with air pollutions. Distributed energy sources (DERs) in Microgrid are usually interfaced with the utility grid by inverters, so the characteristics of Microgrid stability are much different from that of a traditional grid. However, the classifications, guidelines, and analysis method of Microgrid stability are well behind of the Microgrid development. In this paper, a Microgrid stability classification methodology is proposed on the basis of the of Microgrid characteristics investigation, which considers the Microgrid operation mode, types of disturbance and time frame. Then a comprehensive review of the body of research on Microgrid stability is presented in order to identify and advance the field. Finally, some challenges and suggestions of Microgrid stability for further researches are discussed.

Neutrino flux prediction at MiniBooNE

Abstract: The booster neutrino experiment (MiniBooNE) searches for {nu}{sub {mu}}{yields}{nu}{sub e} oscillations using the O(1 GeV) neutrino beam produced by the booster synchrotron at the Fermi National Accelerator Laboratory). The booster delivers protons with 8 GeV kinetic energy (8.89 GeV/c momentum) to a beryllium target, producing neutrinos from the decay of secondary particles in the beam line. We describe the Monte Carlo simulation methods used to estimate the flux of neutrinos from the beam line incident on the MiniBooNE detector for both polarities of the focusing horn. The simulation uses the Geant4 framework for propagating particles, accounting for electromagnetic processes and hadronic interactions in the beam line materials, as well as the decay of particles. The absolute double differential cross sections of pion and kaon production in the simulation have been tuned to match external measurements, as have the hadronic cross sections for nucleons and pions. The statistical precision of the flux predictions is enhanced through reweighting and resampling techniques. Systematic errors in the flux estimation have been determined by varying parameters within their uncertainties, accounting for correlations where appropriate.

Ultraviolet disinfection of juice products in laminar and turbulent flow reactors

Abstract: Individual physical and chemical factors were examined in a model fluid for their effects on the efficacy of UV light on the destruction of Escherichia coli K-12 bacteria using laminar and turbulent flow treatment systems. Factors unique to juice, such as Brix and pH, did not exhibit a large effect over the range tested when examined individually. The single factor found to consistently affect the efficacy of UV light inactivation in juice was absorbance. Particulate material resulted in apparent increased rates of UV killing when solutions of equal absorption coefficients were compared. The flow rates and mixing in the turbulent flow also affected microbial inactivation: the higher the flow rates the higher inactivation rates in turbulent flow UV reactor. Regression equations were developed to describe the relationship between the rate of reduction of E. coli K-12 and absorption coefficient in a thin film reactor and for turbulent flow UV reactor. Running biodosimetry test with minimum and maximum flow rates is recommended to ascertain safe UV disinfection.
