A fixed point theorem for G-monotone multivalued mapping with application to nonlinear integral equations
2017
We extend notion and theorem of [21] to the case of a multivalued mapping defined on a metric space endowed with a finite number of graphs. We also construct an example to show the generality of our result over existing results. Finally, we give an application to nonlinear integral equations
IMPROVEMENTS IN THE SYSTEMS-BASED MODELS GENERATOR SIGEM
1994
Program generators, for us, are computer programs that produce other computer programs. SIGEM is an expert system program generator that can help in the modeling process of real systems. It is associated with a methodology well adapted to modeling practice. In this paper, we present and compare this methodology with other similar ones. Static models (databases), dynamic models, rule-based expert systems, literal and/or numerical variables, probabilistic uncertainty in data and in functions, dimensioned variables, discrete event simulation, and other related problems can be treated with this methodology. We suggest a systems modeling methodology and a programming tool to increase generality …
A Nullclines Approach to the Study of 2D Artificial Network
2019

 
 The system of two the first order ordinary differential equations arising in the gene regulatory networks theory is studied. The structure of attractors for this system is described for three important behavioral cases: activation, inhibition, mixed activation-inhibition. The geometrical approach combined with the vector field analysis allows treating the problem in full generality. A number of propositions are stated and the proof is geometrical, avoiding complex analytic. Although not all the possible cases are considered, the instructions are given what to do in any particular situation.
Bounded Seed-AGI
2014
Four principal features of autonomous control systems are left both unaddressed and unaddressable by present-day engineering methodologies: (1) The ability to operate effectively in environments that are only partially known at design time; (2) A level of generality that allows a system to re-assess and re-define the fulfillment of its mission in light of unexpected constraints or other unforeseen changes in the environment; (3) The ability to operate effectively in environments of significant complexity; and (4) The ability to degrade gracefully—how it can continue striving to achieve its main goals when resources become scarce, or in light of other expected or unexpected constraining fact…
Varying Definitions of Abundance and Incomplete Assemblages Challenge the Generality of the Interspecific Abundance—Distribution Relationships
2011
Empirical evidence does not fully support the universal nature of the positive interspecific abundance—distribution relationship. We have earlier documented a negative relationship for butterfly species in Finland, but recently our view was again challenged using a small subset of Finnish butterflies as apparent evidence. Here we scrutinize the critique and identify some general conceptual challenges in analyses of interspecific abundance—distribution relationships. We identify the common problem that the abundance—distribution studies include only a small subset of species, and thus reveal only sample characteristics, not overall patterns in complete assemblages. Small subsets of species a…
Analysis of the Standard Definition of Cosmopolitanism
2021
This chapter investigates the traditional definition of cosmopolitanism which understands cosmopolitanism as moral egalitarianism. It sets out in detail how the three core elements (individualism, universality, and generality) allow so much room for interpretation that the definition hardly provides any information on what moral egalitarianism means. It confirms that cosmopolitanism as moral egalitarianism includes almost all theories of global justice, even such that are commonly seen as opposing positions.
The exploitation of distributional information in syllable processing
2004
There is now growing evidence that people are sensitive to the statistical regularities embedded into linguistic utterances, but the exact nature of the distributional information to which human performance is sensitive is an issue that has been surprisingly neglected as yet. In order to address this issue, we first propose an overview of some basic measures of association, going from the simple co-occurrence frequency to the normative measure of contingency, rw: We then report an experiment collecting judgments of word-likeness as a function of the relationship between the phonemes composing the rimes (VC). The contingency between Vs and Cs, as assessed by rw; was the best predictor of chi…
Areal Typology and Grammaticalization
1996
Grammaticalization processes in East and mainland South East Asian languages show remarkable areal parallels within the domain of the verb and the noun. Since language contact increases processes of reanalysis it supports grammaticalization and its cross-linguistic similarity. Grammaticalization processes are governed by attractor positions (cf. 1.1.3.) and pathways of grammaticalization (cf. 1.1..4.). The former is a good parameter for making areal distinctions, the latter is of areal relevance only within the domain of the verb. Because of attractor positions, grammaticalization processes are not necessarily slow and gradual. The distribution of attractor positions relative to each other …
On a Quantitative Measure for Modularity Based on Information Theory
2005
The concept of modularity appears to be crucial for many questions in the field of Artificial Life research. However, there have not been many quantitative measures for modularity that are both general and viable. In this paper we introduce a measure for modularity based on information theory. Due to the generality of the information theory formalism, this measure can be applied to various problems and models; some connections to other formalisms are presented.
Tuning continua and keyboard layouts
2008
Previous work has demonstrated the existence of keyboard layouts capable of maintaining consistent fingerings across a parametrized family of tunings. This paper describes the general principles underlying layouts that are invariant in both transposition and tuning. Straightforward computational methods for determining appropriate bases for a regular temperament are given in terms of a row-reduced matrix for the temperament-mapping. A concrete description of the range over which consistent fingering can be maintained is described by the valid tuning range. Measures of the resulting keyboard layouts allow direct comparison of the ease with which various chordal and scalic patterns can be fin…
