      parameters
    The essential dimension is a numerical invariant of the group; it is often equal to the minimal number of independent parameters required to describe all algebraic objects of a certain type.
          
    We show that the structure of a block outside the critical hyperplanes of category O over a symmetrizable Kac-Moody algebra depends only on the corresponding integral Weyl group and its action on the parameters of the Verma modules.
          
    Quantitative parameters in an analog of the Beurling-Pollard theorem differ from those for A.
          
    Quantitative parameters in an analog of the Beurling-Pollard theorem differ from those for A.
          
    In this article we consider the question when one can generate a Weyl- Heisenberg frame for l2(?) with shift parameters N, M-1 (integer N, M) by sampling a Weyl-Heisenberg frame for L2(?) with the same shift parameters at the integers.

      parameter
    In the second example, we obtain a proof of the Chalyh-Veselov conjecture that the Calogero-Moser system with integer parameter is algebraically integrable, using the results of Felder and Varchenko.
          
    The quantum toroidal action on the Fock space depends on a certain parameter κ.
          
    We find that with a specific choice of this parameter, the action on the Fock spaces gives rise to the toroidal action on irreducible level-1 highest weight modules of the affine quantum algebra.
          
    Similarly, by a specific choice of the parameter, the level (1,0) vertex representation of the quantum totoidal algebra gives rise to a structure on irreducible level-1 highest weight-modules.
          
    As a consequence, there is either a unique set, or an (almost) unique two-parameter set of Weyl group invariant quantum zonal spherical functions associated to an irreducible symmetric pair.

      parametric
    We consider 3-parametric polynomialsPμ*(x; q, t, s) which replace theAn-series interpolation Macdonald polynomialsPμ*(x; q, t) for theBCn-type root system.
          
    We also prove a binomial formula for 6-parametric Koornwinder polynomials.
          
    As a consequence this also holds for all functions or curves obtained as the limit of this procedure, such as the Bernstein polynomials, Bézier and spline parametric curves, etc.
          
    An algorithm is derived for determining such a set of perturbation polynomials which are subject to certain constrains at the endpoints of a prescribed parametric interval and minimized in a certain sense.
          
    In this paper, the estimation method based on the "generalized profile likelihood" for the conditionally parametric models in the paper given by Severini and Wong (1992) is extended to fixed design semiparametric nonlinear regression models.

      parameter e
    The estimated thickness of the explosive-instability zone in the icy crust of Ganymede (under the assumption that the crust is ~75 km thick) ranges from ~7 to ~27 km at depths from ~40 to ~67 km, depending on the scaling parameter E = 0.2-1.
          
    For Titan, if its crust is ~100 km thick, the thickness of the unstable layer is similarly estimated to range from ~15 to ~55 km at depths from ~37 to ~92 km for a scaling parameter E lying within the range 0.2-1.
          
    The sums were found in an investigation of the limit of the Coulomb Green's function G(r, r', E), where the energy parameter E approaches an atomic energy level: E → En, En = -Z2/2n2.
          
    Components of plasma of a barrier discharge in xenon are calculated for various values of the parameter E/N.
          
    It is shown that the energy stored in the inductance of the discharge circuit can form a prepulse capable of depositing most of the energy in the active mixture for nearoptimum values of the parameter E/p.

    本文利用近似法求出两种极值調节系統在随机干扰影响下搜索損耗的数学期望,因而可以在具体条件下比較两种調节器的优缺点。在正态平稳随机干扰下,相关搜索法对較强的輸入端干扰是适宜的;反之,在較弱的輸入端干扰时,一般步进搜索法比較有利。計算結果也給出了在各种干扰强度下步进法的最佳步长及相关法的最佳搜索信号振幅,这些都是調节器的重要参数

    This is a continuation of a previous paper "The Dynamic Behaviors of a Self-biased Bistable Multivibrator". A criterion is obtained in which the effect of distributed capacitances and component tolerance under worst combinations are considered as the bases for design. Experimental results show that the method of design introduced in this paper is effective.

    本文是“触发器动态研究”一文的继续,介绍了一个比较简单的动态设计方法。文中考虑了各种分布电容的影响。当电路参数发生变化且处于最不利搭配时,触发器仍具有“交点在U_T前沿的单调翻转过程”。实验结果表明,本文所介绍的设计方法是有效的。

    The thermodynamic functions of an ideal subetance represented by van der Waals equation are obtained with the help of the condition that these functions reduce to those of a perfect gas in the limiting case of vanisning prassure. The volumes of the liquid state and gas state in coexistence as determined by Maxwell's rule of equal areas are expressed in a parametrie form. The nature of the dependence of the constants a and b on the chemical composition of the gas is briefly considered.
