Classifying expansions of the real field by complex subgroups
… real field by multiplicative subgroups of the complex numbers. We first consider expansions by a subgroup generated by an element of the unit circle and a positive real number. We then consider expansions by a subgroup generated by a complex number and a positive real number. In both of these …

Números complexos graduados e avaliação de desempenho de classificadores
… a linguistic approach based in Fuzzy Complex Numbers for the multi-criteria evaluation of classification algorithms was proposed. However, when the absolute values are very close, this approach suggests a ranking with a large number of ties. In order to solve this problem, this work …

ΧΑΡΑΚΤΗΡΙΣΜΟΣ ΔΥΝΑΜΟΣΕΙΡΩΝ ΜΕ ΜΕΡΙΚΑ ΑΘΡΟΙΣΜΑΤΑ ΠΑΝΩ ΣΕ ΠΕΠΕΡΑΣΜΕΝΟ ΠΛΗΘΟΣ ΚΥΚΛΩΝ
… A NONDENUMERABLESUBSET OF (0,2Π) LIE ON A FINITE NUMBER OF CIRCLES (A PRIORI DEPENDINGON X) IN THE COMPLEX PLANE. THE MAIN RESULT OF THIS PAPER IS THAT FOR EVERY MEMBER OF THE CLASS K, THERE EXIST A COMPLEX NUMBER Ω, /Ω/=1, AND TWO POSITIVE INTEGERS Ν,Κ, N<K, SUCH THAT FOR THE COEFFICIENTS CN WE …

Rank 3 permuation characters and maximal subgroups
… character or permutation module over the complex number field of G on the cosets G/H. Let H and K be subgroups of G. We say 1 \(\frac{G}{H}\) \(\leq\) 1\(\frac{G}{K}\)if 1 \(\frac{G}{K}\) \(\leq\) -1\(\frac{G}{H}\)is either 0 or a character of G. Also a finite group G is called nearly …

An investigation into the synthesis, structural characterisation, thermal and polymorphic behaviour of organic crystalline materials
The organic solid state appears in a complex number of forms. The design, synthesis and application of solid state organic materials have a big impact upon society, e.g. pharmaceuticals. Traditionally, the process of selecting active pharmaceutical ingredients (APIs) was limited to free drug or …

Calculation of gas-wall heat transfer from pressure and volume data for spaces with inflow and outflow
… been successfully predicted with the use of a complex Nusselt number. Since a complex,number has both a magnitude and a phase, a complex Nusselt number can describe the phase shift between temperature difference and heat transfer. Quasi - steady heat transfer models, such as Newton's Law of …

Finite dimensional representations of sympletic reflection algebras for wreath products
… ... and to the parameters (k, c), where k is a complex number (occurring only for n > 1), and c a class function on the set of nontrivial elements of ... In particular, we construct, for the first time, families of irreducible finite dimensional modules when ... is not cyclic, n > 1, and (k, c) …

Frequency dependent impedance of stranded conductors using the subdivision method
… resistances and inductances are placed into a complex impedance matrix which is then reduced through mathematical manipulations to obtain a single complex number that represents the equivalent resistance and inductance of the whole conductor. The advantage of this method is that it …

Measurements of in-cylinder heat transfer with inflow-produced turbulence
… been successfully predicted with the use of a complex Nusselt number; since a complex number has both a magnitude and a phase, a complex Nusselt number can describe the phase shift between temperature and heat transfer. Quasi-steady heat transfer models, such as Newton's Law of Cooling, do not …

Random perturbations of delay differential equations at the verge of instability and periodically driven nonlinear oscillators
… eigenvalues) lie on the imaginary axis of the complex plane, and all other roots have negative real parts (stable eigenvalues). The effect of deterministic perturbations on such DDE is analytically well-studied in the literature. For noise perturbations with noise as a Wiener process, the …
