This paper presents general definitions of compensation and noncompensation in M C D M within the framework of Multiattribute Preference Structures. The interest of using a more or less compensatory aggregation procedure is discussed. General aggregation procedures, that allow to mix compensatory and noncompensatory features in a consistent way, are introduced. They receive a complete axiomatic...

In this paper a user evaluation is proposed to assess the effectiveness of systems based on multidimensional relevance assessment. First of all, we introduce our approach to multidimensional modeling and aggregation, and the criteria used for the experiments. Then, we describe how the user evaluation has been performed, and finally, we discuss the results obtained.

The expected behaviour of the “difference index” (Metzger, Shapiro, Mosimann & Vinton, 1968) has been examined under simple assumptions. Provided that it is only used to compare the compositions of proteins of equal or near-equal length, it can be interpreted to provide an estimate of the number of differences between the two sequences. Results with several pairs of proteins are in good agreeme...

Two-dimensional fractionation method suitable for analyzing oligonucleotide mixtures in the microRNA size range was devised. In this system, mobility of oligo-nucleotide is affected by its base composition in both dimensions. Thus, complex mixtures of oligonucleotides with similar chain length can be effectively fractionated.

The text describes the procedure used as a part of a collaboration combining visual and sonic processes to build a generative electronic landscape for an installation. Initially the procedure used to develop the algorithm for the visual evolution of the landscape is described in terms of the visual process. Following this, the description of the sonic design of the mix to be controlled by the l...

A composition σ = a1a2 . . . am of n is an ordered collection of positive integers whose sum is n. An element ai in σ is a strong (weak) record if ai > aj (ai ≥ aj) for all j = 1, 2, . . . , i− 1. Furthermore, the position of this record is i. We derive generating functions for the total number of strong (weak) records in all compositions of n, as well as for the sum of the positions of the rec...

Let d be a fixed nonnegative integer. We say that we have an ascent of size d or more at position i if ai+1 ≥ ai + d. In (3) the present authors found the distribution of the number of ascents of size d or more in compositions of n. In this paper we study various statistics relating to the first ascent of size d or more in compositions of n. In particular we find the average initial height, end...

A novel method for estimating the shear wave speed from crawling waves based on the amplitude modulation-frequency modulation model is proposed. Our method consists of a two-step approach for estimating the stiffness parameter at the central region of the material of interest. First, narrowband signals are isolated in the time dimension to recover the locally strongest component and to reject d...

A cardinal related to compositions of Sierpiński–Zygmund functions from the left, cleft(SZ), will be considered. We answer a question of K. Ciesielski and T. Natkaniec. In particular, we show that cl(SZ) = (2c)+ if R is not a union of less than c-many meager sets and c is a limit cardinal. If c = ω1, then cl(SZ) is equal to the bounding number of c.
