Loaded-frequency selective surface
Frontiers of Electrical and Electronic Engineering in China, 2005AbstractIn this paper a new frequency‐selective surface (FSS) with loadings, is introduced and analyzed using period moments methods. The simulated results show that FSS may operate in different bands and especially generate a large reduction in the resonant frequency for a fixed unit‐cell size through different loadings.

Equipment Selection for Surface Mining: A Review
Interfaces, 2014One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader fleet. We refer to this problem as the equipment selection problem (ESP). In this paper, we describe the ESP in the context of surface mining and discuss related problems and applications.

Miniaturized frequency selective surface and broadband frequency selective surface design
2016 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2016This paper presents the results of our research in the field of frequency selective surface in recent years. Aiming at the traditional passive frequency selective surface (FSS) in this paper, we mainly do two aspects of research work, which is the research of the small frequency selective surface and the research of the ultra wide band frequency ...

Surface Selective Deconstruction
Fractals, 1997Two toy models for surface and interface disaggregation are introduced and some considerations on their relevance for real physico-chemical processes are presented. The models are studied by means of Monte Carlo simulations in 1+1 dimensions and the scaling laws of the interface width w(L, t) are determined.

Selection of Appropriate Support Surfaces
Journal of Wound, Ostomy and Continence Nursing, 1995Many claims are made regarding the appropriate selection of support surfaces. ET nurses do not need to "reinvent the wheel" when they decide which system is best for their patients, but they do need to be aware of the most current scientific and expert recommendations.

Natural selection on Plasmodium surface proteins
Molecular and Biochemical Parasitology, 1995Numbers of synonymous (ds) and nonsynonymous (dN) nucleotide substitutions per site were analysed in eight polymorphic Plasmodium genes: circumsporozoite protein gene (CSP), sporozoite surface protein 2 (thrombospondin related anonymous protein, TRAP), merozoite surface antigen 2 (MSA-2), apical membrane antigen 1 (PF83), liver-stage antigen-1 (LSA-1),

Selection of surfacing treatments
Tribology International, 1978Abstract Satisfactory performance of surfaced components depends upon careful selection procedures, as well as good surfacing practice. After a review of available surfacing treatments and a comparison of their principal characteristics, a systematic approach to the problems of selection against wear is discussed, and the ancillary factors that must ...

Thermoelectroconvection near charge-selective surfaces
Physical Review E, 2015A new kind of instability caused by Joule heating near charge-selective surfaces (permselective membranes, electrodes, or systems of micro- and nanochannels) is investigated theoretically using a model based on the Rubinstein-Zaltzman approach. A simple relation is derived for the marginal stability curves: Joule heating can either destabilize or ...

The Journal of Chemical Physics, 1982
The modification of the absorption, emission, and Raman scattering intensities of molecules near metal surfaces is discussed with emphasis on the last. These modifications are usually referred to as surface selection rules. We show that in Raman scattering, the ‘‘rule,’’ which states that only those modes will be active which belong to the irreducible ...
