We generalize ∇(A), which was introduced in [Sch∞], to larger cardinals. For a regular cardinal κ > א0 we denote by ∇κ(A) the statement that A ⊆ κ and for all regular θ > κ, {X ∈ [Lθ[A] ] <κ : X ∩ κ ∈ κ ∧ otp(X ∩ Ord) ∈ Card} is stationary in [Lθ[A] ] . It was shown in [Sch∞] that ∇א1(A) can hold in a set-generic extension of L. We here prove that ∇א2(A) can hold in a set-generic extension of L...

Let C[[x1, . . . ,xn]] (brie£y C [[x]], where xˆ (x1, . . . ,xn) is the vector of indeterminates) be the ring of formal power series in n indeterminates x1, . . . ,xn with complex coe¤cients.We consider in this paper formal power series transformations F by which we understand automorphisms F of C[[x]] which are continuous with respect to the order topology (i.e., order preserving) and leave ev...

The main objective of this study is to propose a methodology to build a parametric linear model of Flexible Multibody Systems for control design. This approach uses a combined Finite Element State Space Approach based on component modes synthesis and double-port approach. The proposed scheme offers the advantage of automatic assembly of substructures, preserving the elastic dynamical behavior o...

Fever: a Clinical Study. By T. J. Maclagan, M.D. London: J. & A. Churchill. 1888. Dr. Maclagan has above all things the pen of a ready writer, and this book forms no exception in respect of quality to his previous publications. It is so pleasant to peruse a book whose grammar is irreproachable, and style attractive. In the space of something over 160 pages, Dr. Maclagan enunciates his theories ...

The aim of this paper is to give some connections between the structure of an abelian finite group and the structure of its subgroup lattice. Let (G, +) be an abelian group. Then the set L(G) of subgroups of G is a modular and complete lattice. Moreover, we suppose that G is finite of order n. If L n is the divisors lattice of n, then the following function is well defined: ord : L(G) −→ L n , ...

We study the q-Cli ord algebras Clq2(N; c ), called FRT{Cli ord algebras, introduced by Faddeev, Reshetikhin and Takhtajan. It is shown that Clq2(N; c ) acts on the q-exterior algebra (O q2 ). Moreover, explicit formulas for the embedding of Uq2(soN ) into Clq2(N; c ) and its relation to the vector and spin representations of Uq2(soN ) are given and proved. MSC 2000: 81R50, 15A66

100-150 ord) Responding to the climate change challenge requires a massive development and diffusion of carbon neutral technologies and, thus, emergence and growth of new socio-technical systems. This paper contributes to an improved understanding of the formative phase of new technological innovation systems (TIS) by outlining a framework for analysing TIS dynamics in terms of structural growt...

Control of dispersion in fibre optical waveguides is of critical importance to optical fibre communications systems and more recently for continuum generation from the ultraviolet to the mid-infrared. The wavelength at which the group velocity dispersion crosses zero can be set by varying fibre core diameter or index step. Moreover, sophisticated methods to manipulate higher-order dispersion so...

Sammensatte ord skaper problemer ved ulike former for automatisk analyse av vokabularet i en tekst, f.eks, ved frekvensstudier. Problemet består i at menings­ innholdet i et sammensatt ord i mange tilfeller også kan beskrives i et uttrykk med de tilsvarende usammen­ satte ordene. I tekstsøking kan f.eks, de sammensatte ordene føre til at man ikke finner de dokumentene man søker etter fordi det ...
