  • Chernov’s Compensation Principle and the effect of rodent community completeness on the variability of bank vole (Clethrionomys glareolus) population in the Middle Urals
    Russian Journal of Ecology, 2017
    Co-Authors: A. G. Vasil’ev, I. A. Vasil’eva, Yu. V. Gorodilova, N. L. Dobrinskii
    Abstract:

    Using methods of geometric morphometrics, significant differences have been revealed in manifestations of variability and morphological disparity in allochronous samples from the population of model species, the bank vole (Clethrionomys glareolus Schreb. 1780), in the Middle Urals at different levels of rodent community (taxocene) completeness in different years. Two states of the taxocene—oligospecific (two species) and polyspecific (five species)—and the level of relative abundance of bank voles (high or low) have been taken into account. Comparative analysis of variation in the size and shape of the mandible in same-aged (late-summer) young of the year has shown that significant morphogenetic differences exist between the animals sampled from the rodent taxocene at its different states (oligospecific and polyspecific) and, to a lesser extent, at high and low levels of abundance. The level of variation and the parameter of intragroup morphological disparity (MNND) in the mandible shape reach a maximum when the community has a reduced composition and decrease to a minimum when its composition is complete (i.e., in the oligo- and polyspecific taxocene). A parallelism is observed in the manifestation of morphofunctional changes of the mandible in male and female voles under conditions when the taxocene has high abundance and oligospecific composition or low abundance but polyspecific composition. Different morphogenetic responses of the population to oligo- and polyspecific composition of the community are considered as a compensatory increase of morphological disparity in the dominant species (the bank vole) under conditions of incomplete composition of the taxocene and low population density, in accordance with Chernov’s ecological Compensation Principle.

  • the probabilistic evaluation of net present value of electric power distribution systems based on the kaldor hicks Compensation Principle
    IEEE Transactions on Power Systems, 2018
    Co-Authors: Gerald T. Heydt
    Abstract:

    The decision to proceed with a distribution engineering expansion project is often preceded by some form of cost to benefit analysis. The Kaldor–Hicks Compensation Principle is a criterion that assists in this analysis by the evaluation of net present value over the expected project life. This paper discusses this Principle applied to power distribution systems. A probabilistic formulation is proposed to capture uncertainty in cost and benefit data. In effect, the approach models ranges of value of project parameters. While the method does not determine whether to proceed with a given project, it does give a measure of the value of the engineering economic efficiency. The method is especially valuable for cases of “next generation” systems, and this is illustrated in this paper.

  • A Feedforward Decoupling Dynamic Matrix Control of Heavy Oil Separated Process with Smith Predictive Compensation Principle
    2019 12th Asian Control Conference (ASCC), 2019
    Co-Authors: Di Zhang, Yalin Wang
    Abstract:

    The actual refining processes exist delays and the control effect is sensitive to the disturbance and the model mismatch, which are likely the reasons of control failure. Motivated by this problem, a feedforward decoupling dynamic matrix control with Smith predictive Compensation Principle (SF-DMC) is proposed for the heavy oil separated process. In the aspect of algorithm, the dynamic matrix control (DMC) is combined with the Smith predictive Principle to compensate the delays and the influence of disturbance. Based on the model analysis, the primary interaction relationships between the manipulated variables and the controlled variables are reserved, and the minor interaction relationships of the manipulated variables and the controlled variables are introduced as feedforward to improve the control performance. Finally, the double-input and double-output classical heavy oil fractionation tower model is used to confirm the effectiveness of the proposed method.

  • The Role and Resolution of the Compensation Principle in Society: Part One — The Role
    Essays on the Economic Role of Government, 1992
    Co-Authors: Warren J. Samuels
    Abstract:

    In this chapter the Compensation problem is explored in the light of radical indeterminacy, selective perception and the nature and operation of the legal system. The Compensation Principle is shown to be functional as psychic balm and legitimation of the institution of property and the basic organisation of society, and not the protection of particular property rights, except selectively. Conventional legal and economic treatment of Compensation issues — for example, the conflicting, conclusionary and tautological taking issue — is thus shown not to reach the fundamentals of the system of property, the legal system and the roles thereof in society.

  • Intra- and Interpopulation Odontological Variability in the Gray Red-backed Vole (Craseomys rufocanus) and Yu.I. Chernov’s Compensation Principle
    Russian Journal of Ecology, 2020
    Co-Authors: A. G. Vasil’ev, V. N. Bol’shakov, I. A. Vasil’eva
    Abstract:

    — Methods of geometric morphometrics have been used to study geographic and chronographic forms of variation in the shape of the upper third molar (M3) in the gray red-backed vole C. rufocanus, a petrophilic rodent specialized to mountain habitats in the Urals. It has been shown that sexual dimorphism in M3 shape increases in the direction from the Southern to the Polar Urals. In the Middle Urals, differences in M3 shape (more distinct in males than in females) have been revealed between samples taken in years of high and low abundance of the species, which are apparently conditioned by a switch in tooth morphogenesis. This is suggestive of change in the morphofunctional properties of teeth and in related trophic preferences of males and females, i.e., in the possibility for them to consume different spectra of food resources. The increase in M3 sexual dimorphism in the south–north direction and in low-mountain biotopes (not common for the species) is in agreement with Chernov’s Compensation Principle manifested at the intra- and interpopulation levels, as it helps to alleviate trophic competition between males and females. The phenotypic plasticity of teeth provides for population-cenotic stability of the species in climatically unfavorable years and in atypical biotopes and environmental conditions of the Polar Ural Mountains.
