  • spin wave logic devices based on isotropic forward volume magnetostatic waves
    Applied Physics Letters, 2015
    Co-Authors: Stefan Klingler, Philipp Pirro, Thomas Bracher, B Leven, B Hillebrands, A V Chumak
    Abstract:

    We propose the utilization of isotropic forward volume magnetostatic spin waves in modern wave-based logic devices and suggest a Concrete Design for a spin-wave majority gate operating with these waves. We demonstrate by numerical simulations that the proposed out-of-plane magnetized majority gate overcomes the limitations of anisotropic in-plane magnetized majority gates due to the high spin-wave transmission through the gate, which enables a reduced energy consumption of these devices. Moreover, the functionality of the out-of-plane majority gate is increased due to the lack of parasitic generation of short-wavelength exchange spin waves.

  • analytical model for frp confined circular reinforced Concrete columns
    Journal of Composites for Construction, 2008
    Co-Authors: Rami Eid, Patrick Paultre
    Abstract:

    One disadvantage of most available stress–strain models for Concrete confined with fiber-reinforced polymer (FRP) composites is that they do not take into consideration the interaction between the internal lateral steel reinforcement and the external FRP sheets. According to most structural Concrete Design codes, Concrete columns must contain minimum amounts of longitudinal and transverse reinforcement. Therefore, Concrete columns that have to be retrofitted (and therefore confined) with FRP sheets usually contain lateral steel. Hence, the retrofitted Concrete column is under two actions of confinement: the action due to the FRP and that due to the steel ties. This paper presents a new Designed-oriented confinement model for the axial and lateral behavior of circular Concrete columns confined with steel ties, FRP composites, and both steel ties and FRP composites. Comparison with experimental results of confined Concrete stress–strain curves shows good agreement between the test and predicted results.

  • code provisions for high strength Concrete an international perspective
    Concrete international, 2003
    Co-Authors: Patrick Paultre, Denis Mitchell
    Abstract:

    This article compares some of the provisions from five different codes of practice--the American Concrete Institute Building Code Requirements for Structural Concrete, the Comite Euro-International du Beton Model Code, the European Committee for Standardization for Design of Concrete Structures, the Canadian Standards Association for Design of Concrete Structures and the Standards Association of New Zealand Concrete Design Standard--for the structural Design of elements made with high strength Concrete. While codes from different countries have similar objectives, they sometimes have significant differences in their requirements for the Design of high-strength Concrete members. These differences often reflect the region/country's prior state of the art and tradition. Provisions concerning compressive strength limits, load and resistance factors, specified and characteristic strengths, modulus of elasticity, Concrete tensile strength, minimum reinforcement for flexure, stress distributions for determining the nominal resistances under flexure and axial loads, and column confinement for seismic Design are compared.

  • trajectory tracking control of port controlled hamiltonian systems via generalized canonical transformations
    Automatica, 2003
    Co-Authors: Kenji Fujimoto, Kazunori Sakurama, Toshiharu Sugie
    Abstract:

    This paper addresses trajectory tracking control of port-controlled Hamiltonian systems via generalized canonical transformations and passivity-based control. The main strategy adopted in this paper is to construct an error system, which describes the dynamics of the tracking error, by a passive port-controlled Hamiltonian system. After obtaining the error system, tracking control of the original system can be achieved by stabilizing the error system via passivity-based approach. First, a fundamental framework is provided for constructing the error system via generalized canonical transformations. Then a Concrete Design procedure is derived for a class of electro-mechanical systems. Furthermore, the proposed method is applied to a magnetic levitation system and laboratory experiments demonstrate its effectiveness.
