Biodiesel (FAME) is increasingly used in diesel fuel formulations, however, even small amounts of biodiesel are not appropriate in certain engine applications. For example, biodiesel in aviation fuel and in back-up electric generators used in nuclear power plants can cause significant issues. Likewise, the presence of trace biodiesel in diesel fuel specified for marine pleasure crafts is proble...

Polynomial relations for generators of su(2) Lie algebra in arbitrary representations are found. They generalize usual relation for Pauli operators in spin 1/2 case and permit to construct modified Holstein-Primakoff transformations in finite dimensional Fock spaces. The connection between su(2) Lie algebra and q-oscillators with a root of unity q-parameter is considered. The meaning of the pol...

This review deals with applications of activation analysis to geological samples : , minerals and rocks . The various activation sources suitable for tb.is purpose are discussed. Applications using isotopic neutron sources are reviewed in some detail , those using neutron generators are discussed on a rrore general basis . Present trends in instrumental neutron-activation techniques are briefly...

This paper presents generators based on decimated sequences of Generalized Feedback Shift Register (GFSR) generators. The equivalence relation between decimated GFSR generators and Tausworthe generators are presented and a k-distributed initialization scheme is derived. We present decimated GFSR generators that are maximally equidistributed. Timing results of these generators are presented.

Two types of linear congruent.ial random number generator are considered: the conventional one using integer arithmetic and another using polynomial arithmetic over finite fields. We show t.hat most of the long-period random number generators currently used or recently proposed, which include multiple re.:ursive generators, shift register generators, add-with-carry and subtract-with-borrow gene...
