Values of binary mutual diffusion (interdiffusion) coefficients, obtained by using the Taylor dispersion method, for aqueous solutions of γ-cyclodextrin in the concentration range from (0.002 to 0.010) mol ·dm and temperatures (298.15 and 310.15) K are reported. From these experimental results, the hydrodynamic radius values for the γ-cyclodextrin are estimated. Also, the measured diffusion coe...

A formal algorithm of a two-way stratification design described by Bryant et al. (1960) is presented. Also a simple modification is proposed which improves the design.

We introduce a novel method of modelling Tullock rent-seeking contests that avoids the complexities encountered by the ‘best response function’ approach. We analyse contests in which there are many risk averse players differing in their attitudes to risk. We establish that, if every player has a constant degree of absolute risk aversion, a unique equilibrium exists. We also establish comparativ...

The discrete cosine and sine transforms are generalized to a triangular fragment of the honeycomb lattice. The two-variable orbit functions of the Weyl group A2, discretized simultaneously on the weight and root lattices, induce the family of the extended Weyl orbit functions. The periodicity and von Neumann and Dirichlet boundary properties of the extended Weyl orbit functions are detailed. Th...

This paper proposes the use of the Hartley Phase Cepstrum as a tool for signal analysis. The phase of a signal conveys critical information, which is exploited in a variety of applications. The role of phase is particularly important for the case of speech or audio signals. Accurate phase information extraction is a prerequisite for speech applications such as coding, synchronization, synthesis...
