In the crystal structure of the title compound, C(20)H(12)N(6)O(2), the mol-ecules are located on centres of inversion. The complete mol-ecule is almost planar, with a maximum deviation from the mean plane of 0.0657 (1) Å for the O atom. In the crystal, mol-ecules are stacked into columns elongated in the a axis direction. The centroid-centroid distances between the aromatic rings of the mol-ec...

There is a a set E of positive Lebesgue measure and a function nowhere di¤erentiable on E which is di¤erentible in the Lp sense for every positive p at each point of E. For every p 2 (0;1] and every positive integer k there is a set E = E(k; p) of positive measure and a function which for every q < p has k Lq Peano derivatives at every point of E despite not having an Lp kth derivative at any p...

A new class of formal languages will be defined the Distributed Index Languages (DI-languages). The grammar-formalism generating the new class the DI-grammars cover unbound dependencies in a rather natural way. The place of DI-languages in the Chomsky-hierarchy will be determined: Like Aho's indexed Languages, DI-languages represent a proper subclass of Type 1 (contextsensitive languages) and p...

Conventional numerical di erentiation formulas based on interpolating polynomials, operators and lozenge diagrams can be simpli ed to one of the nite di erence approximations based on Taylor series, and closed-form expressions of these nite di erence formulas have already been presented. In this paper, we present new nite di erence formulas, which are more accurate than the available ones, espe...

In this thesis, I propose a robust and easy to implement method to calibrate an IMU without any external equipment. The procedure is based on a multi-position scheme, providing scale and misalignments factors for both the accelerometers and gyroscopes triads, while estimating the sensor biases. The method only requires the sensor to be moved by hand and placed in a set of different, static posi...

Functions We already observed in Section 5.2.2 that a function f : Z → Z is decomposed into elementary functions, i.e., assembly instructions within some basic block. Following the same approach, let us assume that the function f can be expressed as a composition of elementary functions, namely f = λx.h(g1(x, ..., x), ..., gk(x, ..., x)) where h : Zk → Z and gi : Zni → Z. More in general, each ...
