Epistemological Alienation in Scientific Psychology.

This article presents the concept of epistemological alienation in order to examine psychology's epistemological quantitative Paradigm and its connection to political reality. Politzer's work of how mainstream psychology turns the first-person language of the individual into a mechanistic third-person pseudoscience is thoroughly discussed. Consequently, through some marginalized voices within psychology, it is examined how psychologists disregard the subject's own voice, intentionality, meaning and judgment-forming mechanisms promoting instead a naturalistic and mechanistic language, based heavily on psychometric methodology and a false and altered account of psychology's history.

Flow visualisation of a normal shock impinging over a rounded contour bump in a Mach 1.3 free-stream.

Abstract: An experimental study has been conducted to visualise the instantaneous streamwise and spanwise flow patterns of a normal shock wave impinging over a rounded contour bump in a Mach 1.3 free-stream. A quartz-made transparent shock generator was used, so that instantaneous images could be captured during the oil-flow visualisation experiments.

Static and Wind-on Performance of Polymer-Based Pressure-Sensitive Paints Using Platinum and Ruthenium as the Luminophore.

An experimental study has been conducted to investigate the static and wind-on performance of two in-house-developed polymer-based pressure-sensitive paints. Platinum tetrakis (pentafluorophenyl) porphyrin and tris-bathophenanthroline ruthenium II are used as the luminophores of these two polymer-based pressure-sensitive paints. The pressure and temperature sensitivity and the photo-degradation rate of these two pressure-sensitive paints have been investigated.

Penetration Characteristics of Air, Carbon Dioxide and Helium Transverse Sonic Jets in Mach 5 Cross Flow.

An experimental investigation of sonic air, CO and Helium transverse jets in Mach 5 cross flow was carried out over a flat plate. The jet to freestream momentum flux ratio, J, was kept the same for all gases. The unsteady flow topology was examined using high speed schlieren visualisation and PIV.

Luminescent measurement systems for the investigation of a scramjet inlet-isolator.

Scramjets have become a main focus of study for many researchers, due to their application as propulsive devices in hypersonic flight. This entails a detailed understanding of the fluid mechanics involved to be able to design and operate these engines with maximum efficiency even at their off-design conditions. It is the objective of the present cold-flow investigation to study and analyse experimentally the mechanics of the fluid structures encountered within a generic scramjet inlet at M = 5.
