Recent research in the area of Second Language Acquisition has proposed that bilinguals and L2 learners show syntactic indeterminacy when syntactic properties interface with other cognitive domains. Most of the research in this area has focused on the pragmatic use of syntactic properties while the investigation of compliance with a grammatical rule at syntax-related interfaces has not received...

This paper reports an analysis of the acquisition of plosives and implosives by a Fulfulde monolingual child aged from 5 months to 10 months and 29 days. Analyses revealed that before 11 months the child was making use of complex consonant-like implosives and prenasal plosives. We provided new aerodynamic analyses of adult‟s implosive /ɓ/. These aerodynamic data revealed that in Fulfulde this p...

The purpose of this paper is to discuss and clarify the explanations commonly cited for the aerodynamic lift generated by a wing, and to then analyse, as a case study of engineering discovery, the aerodynamic revolutions which have taken place within Formula 1 in the past 40 years. The paper begins with an introduction that provides a succinct summary of the mathematics of fluid mechanics.

This article discusses stress analysis and the shape characteristics of the inflatable wing, and then introduces the design method of inflatable wing, in order to accurately approximate a standard airfoil. It specifically analyses the aerodynamic characteristics of the inflatable wing with the method of CFD, along with comparing to standard airfoil, afterwards we carries out the manufacture of ...

Richtmyer-Meshkov instability (RMI) plays an important role in a broad variety of phenomena in nature and technology and is of special interest in the fields of shockturbulence interaction, supersonic aerodynamic flows, and inertial and magneto-inertial fusion. The instability develops when a shock refracts an interface between two fluids with different values of the acoustic impedance, and RMI...

A novel approach to perform trajectory and aerothermodynamic analysis using the state-of-theart OLAP multi-dimensional database technology will be presented in this publication. An Online Analytical Processing (OLAP) Database Management System integrated to a trajectory code has been developed. The database contains a list of planetary probe architectures and includes vehicle dimensions, trajec...

Applicable Pollutants: Particulate Matter (PM), including particulate matter less than or equal to 10 micrometers (:m) in aerodynamic diameter (PM10), particulate matter less than or equal to 2.5 :m in aerodynamic diameter (PM2.5), and hazardous air pollutants (HAPs) that are in particulate form, such as most metals (mercury is the notable exception, as a significant portion of emissions are in...

Computers have had a twofold impact on the science of aerodynamics. On the one hand numerical simulation may be used to gain new insights into the physics of complex flows. On the other hand computational methods can be used by engineers to predict the aerodynamic characteristics of alternative designs. Assuming that one has the ability to predict the performance, the question then arises of ho...

This paper discusses the contribution of aerodynamic techniques to record phonetic data in the field. New tools allow using automatic calibrations procedures as well as quantifying data in a reliable way. This permits addressing research questions such as patterns of variations of phenomena. Analytic methods show how to interpret data from physical principles and integrate those in adequate mod...

By using a combined analytical–computational methodology, a unified modelling of aerodynamic indicial functions covering the incompressible, subsonic compressible, transonic, and supersonic flight speed regimes is presented. The procedure is carried out in conjunction with a computational fluid dynamic analysis. For a plunging–pitching airfoil, selected unsteady aerodynamic load expressions hav...
