    Opis:
    Fractional-slot concentrated-winding permanent magnet synchronous machines (FSCW-PMSMs) have a good prospect of application in the drive system of electric and hybrid electric vehicles. However, the armature magnetomotive force (MMF) of FSCWPMSM contains a large number of space harmonics, which induce large magnet eddycurrent loss (ECL). To solve this problem, a dual three-phase 10-pole and 24-slot winding layout is proposed.MMFharmonic analysis shows that the 1st, 7th and 17th space-harmonic winding factors of the proposed winding can be reduced by 100%, 87% and 87% respectively, compared with a dual three-phase 10-pole and 12-slot winding. Electromagnetic performances of the proposed machine under rated sinusoidal current supply and space vector pulse-width-modulated (SVPWM) voltage supply are investigated based on 2D finite-element analysis. It is shown that the proposed machine can meet the requirement of torque and efficiency in the full speed range. Especially, magnet ECL can be reduced greatly due to the reduction of the 7th and 17th space harmonics.

    Opis:
    We first prove that the property of strict monotonicity of a~K\"othe space \((E,\|.\|_E)\) and\slash or of its K\"othe dual \((E',\|.\|_{E'})\) can be used successfully to compare the supports of \(x\in E\backslash\{\theta\}\) and \(y\in S(E')\), where \(=\|x\|_E\). Next we prove that any element \(x\in S_{+}(E)\) with \(\mu(T\backslash\operatorname{supp} x)=0\) is a~point of order smoothness in \(E\), whenever \(E\) is an order continuous K\"othe space. Finally, we present formulas for the characteristic of monotonicity of Orlicz function spaces endowed with the Orlicz norm in the case when the generating Orlicz function does not satisfy suitable \(\Delta_2\)-condition or the measure is non-atomic infinite, and some lower and upper estimates for the characteristic of monotonicity of this spaces when the measure is non-atomic and finite.

    https://doi.org/10.26485/0459-6854/2018/68.1/6 Izooptyki, to krzywe, które były znane i rozważane od XVIII wieku. W ostatnim półwieczu badali je między innymi przez Benko, Cieślak, Góźdź, Miernowski i Mozgawa w wielu pracach, na przykład w [1], [2], [3] i [7]. W tej publikacji chcemy zaproponować nowy sposób patrzenia na izooptyki. Dla danego owalu rozważamy jego krzywą dualną na cylindrze Blaschke’go i konstruujemy krzywą dualną do jego izooptyki. Niektóre własności, na przykład utratę wypukłości,  łatwiej jest zaobserwować na krzywej dualnej niż na wyjściowej krzywej. Z analizy w lasności krzywych dualnych do izooptyk otrzymujemy nową postać warunku na wypukość izooptyk.

Nowadays they have been examined inter alia by Benko, Cie´slak, G´o´zd´z, Miernowski and Mozgawa in many papers for example in [1], [2], [3] and [7]. We want to propose a new point of view isoptics. For a given oval we consider a dual curve on Blaschke cylinder and we construct a dual curve for its isoptic. Some properties, for example the loss of convexity is easier to observe on the dual curve than on the given curve. From the analysis of properties of dual curves to isoptics we get a new form of the condition for the convexity of isoptic curves.

    Opis:
    When integral kernel of an integral transform is being formed, it should be the outcome of scalar product differentiation rule if the kernel is supposed to be eventually used as an integrand in a prospective integration. Yet it has already been shown that despite ensuing from properly performed differentiation, the resulting integral kernel contains, beside the covariant differential that is suitable for integration, also a certain contravariant term, which is not appropriate for integration in the same space as the covariant differential. But the contravariant term also can be turned into proper, though multiplicatively inverse covariant differential, if placed within a space that is reciprocal to the given primary space in which the first, covariant differential, is represented naturally. This uncharacteristic conversion of the contravariant expression from the primary space into the reciprocal covariant differential in the dual reciprocal space that is paired with the given primary space, can be considered as indirect proof that pairing of mutually dual reciprocal spaces is necessary in order to properly form operationally legitimate and geometrically valid differential structures. Consequently, the pairing of an infinitesimal descending singularity of the 2D domain of complex numbers with an infinitely ascending singularity deployed in the 1D domain of real numbers requires certain dual reciprocal spatial or quasispatial structures, for the downward transition from 2D descending complex singularities to the 1D ascending “real” singularities to be meaningfully/unambiguously implemented. Furthermore, just as integration by parts formula is a counterpart of the regular product differentiation rule, a new multispatial scalar product integration rule is proposed as a counterpart to the singlespatial product differentiation rule, and introduced by analogy to the latter, “regular” product integration rule.

    Opis:
    Pairing of infinitesimal descending singularity of the 2D domain of complex numbers with an infinitely ascending singularity deployed in the 1D domain of real numbers, where the real singularity can be equated operationally with never-ending, whether countable or not, infinity, requires the employment of a pair of mutually dual reciprocal spaces in order for each of the spaces of the twin quasigeometric structure to be truly operational. Creation of twin quasigeometric structures comprising paired dual reciprocal spaces that are really operational and truly invertible, is the necessary condition for making the notion of operationally sound infinity viable. Although acceptance of the multispatial reality paradigm seems optional, it is shown that even performing legitimate scalar differentiation (in accordance with product differentiation rule) can yield either incomplete or incorrect evaluations of compounded scalar functions. This curious fact implies inevitable need for awareness of conceptual superiority of the multispatial reality paradigm over the former, unspoken and thus unchallenged in the past, single-space reality paradigm, in order to prevent even inadvertent creation of formwise illegitimate, or just somewhat incomplete, pseudodifferentials, which can be obtained even with the use of quite legitimate operational rules of scalar differential calculus.

    Opis:
    We show that the strong dual X' to an infinite-dimensional nuclear (LF)-space is homeomorphic to one of the spaces: $ℝ^ω$, $ℝ^∞$, $Q×ℝ^∞$, $ℝ^ω×ℝ^∞$, or $(ℝ^∞)^ω$, where $ℝ^∞ = lim ℝ^n$ and $Q=[-1,1]^ω$. In particular, the Schwartz space D' of distributions is homeomorphic to $(ℝ^∞)^ω$. As a by-product of the proof we deduce that each infinite-dimensional locally convex space which is a direct limit of metrizable compacta is homeomorphic either to $ℝ^∞$ or to $Q×ℝ^∞$. In particular, the strong dual to any metrizable infinite-dimensional Montel space is homeomorphic either to $ℝ^∞$ or to $Q×ℝ^∞$.

    Opis:
    In this paper, we prove that the topological dual of the Banach space of bounded measurable functions with values in the space of nuclear operators, furnished with the natural topology, is isometrically isomorphic to the space of finitely additive linear operator-valued measures having bounded variation in a Banach space containing the space of bounded linear operators. This is then applied to a stochastic structural control problem. An optimal operator-valued measure, considered as the structural control, is to be chosen so as to minimize fluctuation (volatility). Both existence of optimal policy and necessary conditions of optimality are presented including a conceptual algorithm.
