Numerical Analysis of Various Configurations of Slab Lines (Short Paper)

IEEE Transactions on Microwave Theory and Techniques, 1986
Numerical solutions are presented for the characteristic impedance of various line structures derived from the slab line, which allow the calculation also of the even and odd impedance of coupled slab lines. Some approximated formulas are also derived, which match the numerical results with good precision for a large range of geometrical dimensions of ...

Monitoring of strain profile variations in the RC slab of a short-span railway bridge

Journal of Civil Structural Health Monitoring, 2016
A novel monitoring scheme oriented towards the structural examination of reinforced concrete slabs subject to railway traffic action is presented. Monitoring is based on the measurement of the mean axial strain profile variation in the cross-section of the slab. The strain profile is reconstructed under the assumption of plane sections by measuring the

Magnetostatic Surface Waves in Ferrite Slab Adjacent to Semiconductor (Short Papers)

IEEE Transactions on Microwave Theory and Techniques, 1974
Magnetostatic surface waves propagating along the ferrite slab adjacent to a semiconductor are discussed in this paper. Our numerical results indicate that the conductivity of the semiconductor plays an important role in the determination of the dispersion relation in the case of nondrifting carriers. The backward wave appears for a finite value of the

Deformation of reinforced concrete slabs under short-term dynamic loading

Proceedings. The 8th Russian-Korean International Symposium on Science and Technology, 2004. KORUS 2004., 2005
The given paper presents the results of experimental research describing peculiarities of deformation of supported on four sides reinforced concrete slabs under short-term dynamic loading. The obtained experimental data are compared to those of theoretical calculations.

Short-circuit phenomena: Heat energy drains in composite cylindrical slabs

International Journal of Heat and Mass Transfer, 1983
Abstract A basic theoretical analysis of steady heat flow through laminated cylindrical slabs is carried out to introduce the concept of short-circuited diffusion phenomena. It is seen in the case of a two-layer slab that elevated energy drains are a salient characteristic of such phenomena.

Nuclear slabs with Green’s functions: mean field and short-range correlations

The European Physical Journal Special Topics, 2019
Computational difficulties aside, nonequilibrium Green’s functions appear ideally suited for investigating the dynamics of central nuclear reactions. Many particles actively participate in those reactions. At the two energy extremes for the collisions, the limiting cases of the Green’s function approach have been successful: the time-dependent Hartree ...

Behavior of the Magnetostatic Wave in a Periodically Corrugated YIG Slab (Short Papers)

IEEE Transactions on Microwave Theory and Techniques, 1977
An analysis for the propagation characteristics of the magnetostatic wave in a YIG slab having periodically corrugated surfaces is presented. The Brillouin diagrams, close to the intersection point (omega,K) of m = 0 and m = -1 space harmonics, are obtained for different slab thicknesses, and the nonexistence of leaky wave modes has been established ...

Parametric Equations for Surface Waves In Dielectric Slab (Short Paper)

IEEE Transactions on Microwave Theory and Techniques, 1987
For the dielectric slab it is shown that 1) the dispersion curve for the nth surface wave can be found using parametric equations in which the normalized inside wavenumber K/sub xl/ and the mode number are the parameters, 2) the dispersion curve for the nth surface wave mode can also be found by using parametric equations in which the mode number and a

Rigorously modeling short bent, graded-index dielectric slab waveguides

IEEE Transactions on Microwave Theory and Techniques, 1993
Circularly short bent, graded-index dielectric slab waveguides are mathematically modeled using both a direct integration method and a source-type integral equation method. The former method is easy to implement, requiring only small amounts of computer time.

Effect of Shrinkage on Short-Term Deflection of Reinforced Concrete Beams and Slabs

SP-246: Structural Implications of Shrinkage and Creep of Concrete, 2007
Shrinkage's influence on tension stiffening in flexure and subsequent short-term deflection effects in beams and slabs is investigated. Shrinkage can significantly affect initial short-term response (particularly for laboratory-tested beams used to develop and validate deflection prediction theoretical models), although shrinkage is typically thought ...
