This study proposes a modified version of cultural algorithms (CAs) which benefits from rule-based system for influence function. This rule-based system selects and applies the suitable knowledge source according to the distribution of the solutions. This is important to use appropriate influence function to apply to a specific individual, regarding to its role in the search process. This rule ...

Abstract Plasma-based positron sources are attracting significant attention from the research community, thanks to their rather unique characteristics, which include broad energy tuneability and ultra-short duration, obtainable in a compact relatively inexpensive setup. Here, we show detailed numerical study of beam characteristics at dedicated user target areas proposed for EuPRAXIA facility, ...

The feasibility of novel gamma-ray light sources based on the channeling phenomenon ultrarelativistic charged particles in oriented crystals is demonstrated by means rigorous numerical modeling that accounts for interaction a projectile with all atoms crystalline environment. Accurate predictions are provided brilliance radiation emitted diamond-based undulator 10 GeV positron beam available at...

Vitrimers are polymeric materials that behave as thermosets at room temperature but, when heated, they exhibit a plastic flow similar to thermoplastics, enabling their reprocessability. A series of new bio-based polyamide-polyamine vitrimers synthetized starting from tris(2-aminoethyl)amine and epoxidized methyl oleate, material can be easily prepared renewable resources obtainable both natural...

The acceleration and deceleration of photons m a plasma provides the means lbr a series of new radiation sources. Previous work on a DC to AC Radiation Converter (DARC source) has shown variable acceleration of photons having zero frequency (i.e., an electrostatic field) to belx~een 6 and 100 GHz (I-3). These sources all had poor guiding characteristics resulting in poor power coupling froln th...

Characterizing deepwater reservoirs, their stratigraphy and structure can be highly uncertain due to the extremely limited data. The existence of subseismic scale fine-grained layers can significantly affect oil production of a reservoir, which requires explicitly modelling the uncertainty of these fine-grained fluid barriers. Conventional modeling techniques, such as twopoints statistics, mult...
