The present study focuses on the impact of eddy viscosity turbulence models benchmark INSEAN E779A marine propeller hydroacoustic performance under non-cavitating and open water conditions. In numerical calculations, Realisable k-epsilon (k-?), k-? Shear Stress Transport (k-? SST) Spalart-Allmaras models, which are widely used in hydrodynamic fields, selected. Hydroacoustic model is predicted w...

Analogy has been shown to be important in many key cognitive abilities, including learning, problem solving, creativity and language change. For cognitive models of analogy, the fundamental computational question is how its inherent complexity (its NP-hardness) is solved by the human cognitive system. Indeed, different models of analogical processing can be categorized by the simplification str...

Analogical reasoning is one of the most important techniques used by people, yet it has proved very difficult to represent the process in formal terms amenable to operational implementation in computer algorithms. In this paper we analyse the concept of an analogy and its application to reasoning processes. An analogy is seen to be a partial correspondence between two sYstems. In representing i...

In appreciation of Ffowcs-Williams and Hawkings’ seminal contribution on describing the sound radiation from moving objects, this article discusses a concept taking into account local non-trivial flow effects propagation. The approach is motivated by fact that numerical simulation propagation complete full scale aircraft means volume-discretizing (CAA = Computational AeroAcoustics) methods proh...

I argue that Stephen Wykstra’s much discussed Parent Analogy is helpful in responding to the evidential problem of evil when it expanded upon from a positive skeptical theist framework. This framework, defended by John Depoe, says although we often remain dark about first-order reasons God allows particular instances suffering, can have second-order would create world with seemingly gratuitous ...
