“…Here, the development and operation of safety-critical systems implies an implicit need of managing data, information and knowledge that is generated by the different engineering teams. In this light, it is necessary to emphasize the research advances in Aerospace [105,137,138,150] and Automotive [64,65,72,89,139] engineering. In both cases, the "one-size fits all" is again not true.…”

The present paper introduces and reviews existing technology and research works in the field of scientific programming methods and techniques in data-intensive engineering environments. More specifically, this survey aims to collect those relevant approaches that have faced the challenge of delivering more advanced and intelligent methods taking advantage of the existing large datasets. Although existing tools and techniques have demonstrated their ability to manage complex engineering processes for the development and operation of safety-critical systems, there is an emerging need to know how existing computational science methods will behave to manage large amounts of data. That is why, authors review both existing open issues in the context of engineering with special focus on scientific programming techniques and hybrid approaches. 1193 journal papers have been found as the representative in these areas screening 935 to finally make a full review of 122. Afterwards, a comprehensive mapping between techniques and engineering and nonengineering domains has been conducted to classify and perform a meta-analysis of the current state of the art. As the main result of this work, a set of 10 challenges for future data-intensive engineering environments have been outlined.

This paper studies the problem of sound propagation above a finite impedance plane. For this purpose, a spherical wave based half-space transfer function with velocity is derived and then is applied in the equivalent source method (ESM) to consider the influence of reflections caused by the finite impedance plane. With the half-space transfer function matching the surface velocity to the equivalent sources, the ESM is applied to estimate the sound filed above a finite impedance plane. Through two numerical simulation experiments, in which two vibrating objects, e.g., an oscillating sphere and a simply supported plate, are respectively used, the proposed model is examined. The results validate that the proposed model is feasible and effective to estimate the sound field above a finite impedance plane.

“…While the scattering of linear, or low-amplitude, waves by single and multiple scatterers is a well-developed field with an extensive literature (see, e.g., Refs. [1][2][3][4], less is known about the effects of scatter-ing on nonlinear waves. Abbasov studied the generation of sec-ond harmonics of initially sinusoidal waves incident upon a rigid cylinder.…”

Geometric acoustics, or acoustic ray theory, is used to analyze the scattering of high-amplitude acoustic waves incident upon rigid circular cylinders. Theoretical predictions of the nonlinear evolution of the scattered wave field are provided, as well as measures of the importance of accounting for nonlinearity. An analysis of scattering by many cylinders is also provided, though the effects of multiple scattering are not considered. Provided the characteristic nonlinear distortion length is much larger than a cylinder radius, the nonlinear evolution of the incident wave is shown to be of much greater importance to the overall evolution than the nonlinear evolution of the individual scattered waves.
