Transient wave propagation in a waveguide filled with an inhomogeneous dispersive medium is analyzed. The waveguide is inhomogeneous in the longitudinal direction, but is homogeneously filled in the transverse directions. The analysis is performed in the time domain and is based upon a wave splitting technique and the method of propagators. The propagator maps the exciting field from one position
A major question in organizations is how to support Business Processes (BPs) by an Enterprise Resource Planning (ERP) system. In this paper we present thoughts on designing implementation processes of ERPs using a Service Oriented Architecture (SOA) based perspective: The starting point is based on the idea of decomposing an ERP from a SOA based perspective and thereby supporting automation of imp
Modern chips may contain a large number of embedded test, debug, configuration, and monitoring features, called instruments. An instrument and its instrument data, instrument access procedures, may be pre-developed and reused and instruments may be accessed in different ways through the life-time of the chip, which requires retargeting. To address instruments reuse and retargeting, IEEE P1678 spec
The author shows that the proofs of \n B. H. Arnold\en [Amer. Math. Monthly 56 (1949), 465--466; MR0031725 (11,195h)] and \n I. Niven\en [ibid. 57 (1950), 246--248; MR0035738 (12,4c)] of the fundamental theorem of algebra, based on the Brouwer fixed point theorem, are incomplete. Both Arnold and Niven recognized that the proofs are invalid, and they remarked that no easy remedy seems to save their
A comparison between experimental measurements of the electromagnetic field in boreholes and a mathematical model is made. The transmitting antenna is a rectangular wire loop on the ground and the three orthogonal components of the magnetic field are measured below the ground in the borehole. In the mathematical model the ground is assumed to be a stratified half space with a rectangular wire ante
In this paper the connection between exogamy and partnership dissolution is analyzed using individual level register data for natives and immigrants moving to Sweden after 1968. We study both formally married and cohabiting unions, from the birth of the first child until dissolution of the partnership. Using event history models we study the impact of type of union (endogamous, exogamous with a na
Résumé : Le français écrit est caractérisé par de nombreuses marques morphologiques qui ne se prononcent pas. Cet article pose la question de savoir quand et sur quels constituants de la phrase les apprenants de français L2 font l’accord en nombre, souvent silencieux, à l’écrit. Dans une optique de développement qui s’inspire des travaux de Bartning et Schlyter (2004) dans le domaine du français p
Inorganic binders and dry mortars were stored in room climate and in a freezer over a four-year period. The rate of reaction and flow properties (only dry mortar) were tested to study the influence of storage time and storage temperature on the materials. Material properties were found to change in time and material stored at room temperature showed significantly higher changes than material store
This thesis deals with Chiral Perturbation Theory (ChPT), an effective field theory for the strong force used to describe meson interactions. The work done can be split in two parts. The first one is on ChPT in its standard formulation. This theory has been very successful so far in describing low energetic processes. However, it is still not entirely clear how much it can be trusted for precision
