Radome diagnostics are acquired in the design process, the delivery control and in performance verification of repaired and newly developed radomes. A measured near or far field may indicate deviations, e.g., increased side lobe levels, but the origin of the flaws are not revealed. In this paper, radome diagnostic is performed by visualizing equivalent currents on a radome surface. We localize pha

The present invention relates to a membrane pump and an apparatus comprising such a membrane pump. The membrane pump comprises a pumping chamber and a flexible member separating the pumping chamber into a first accumulation container and a second accumulation container. The flexible member is configured to be movable within the pumping chamber so as to vary a volume relationship between the first

Organic material, about half of which is water soluble, constitutes nearly 80% of the wet-season aerosol mass in the Amazon Basin, while soluble inorganic salts (predominantly ammonium bisulfate) represent about 15%. A detailed analysis of number distributions and the size-dependent chemical composition of the aerosol indicates that, in principle, the sulfate fraction could account for most of the

The present paper suggests a method to consider uncertainties in engineering structures in a computational scheme. Latin hypercube sampling is used to prepare input data of probabilistic parameters for subsequent deterministic simulations where the mechanical response is evaluated. The approach is applied on a pallet rack system where damaged columns and connector stiffnesses are considered as pro

Despite the widely recognized importance of replications in software engineering, industrial replications in software engineering are still rarely reported. Although the literature provides some evidence about the issues and challenges related to conducting experiments and replications the practitioner's view of the issues and challenges has not been fully explored. This paper reports an industria
