The impact of Tween20 surfactant, applied in native form or as colloidal gas aphrons (CGAs), on the extractability/purification enhancement antioxidant compounds from grape skins (GS), compared to conventional solid–liquid extraction (SLE), was evaluated. Three strategies were developed (S1: partial ethanol replacement during SLE with aqueous solutions; S2: CGAs application GS-extract suspensio...

The switched reluctance motor is a singly excited, doubly salient machine which can be used in generation mode by selecting the proper firing angles of the phases. Due to its robustness, it has the potential and the ability to become one the generators to be used in harsh environment. This paper presents an energy conversion by a Switched Reluctance Generator (SRG) when bifilar converter ci...

We construct a pseudorandom generator which uses O(log m + log d + log 3=2 1==) bits and approximates the volume of any combinatorial rectangle in f1; : : : ; mg d to within error. O(log m + log d + log 2 1==) bits. For a subclass of rectangles with at most t log 1== nontriv-ial dimensions and each dimension being an interval, we also give a pseudorandom generator using O(log log d + log 1== lo...

We briefly discuss the current status of NLO QCD automation in the Monte Carlo event generator WHIZARD. The functionality is presented for the explicit study of off-shell top quark production with associated backgrounds at a lepton collider.

In this paper we consider the question of whether NC circuits can generate pseudorandom distributions. While we leave the general question unanswered, we show • Generators computed by NC circuits where each output bit depends on at most 3 input bits (i.e, NC03 circuits) and with stretch factor greater than 4 are not pseudorandom. • A large class of “non-problematic” NC generators with superline...

The on demand generation of source code and its execution is essential if computers are expected to play an active role in information discovery and retrieval. This paper presents a model of implementation of a source code generator, whose purpose is to generate source code on demand. The implementation of the source code generator is fully configurable and its adoption to a new application is ...

this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...
