Can the subaltern speak through WhatsApp? Unearthing the labour/knowledge of digital methodologies
Abstract Prompted by the challenges that Syrian refugees posed to a qualitative WhatsApp survey, this article dissects what researchers and research participants actually do when they ‘produce’ knowledge through digital methods such as WhatsApp. While many refugee participants saw the survey as an opportunity to express their views on social tensions ...

On the Development of Turbulent Wakes from Vortex Streets [PDF]
Wake development behind circular cylinders at Reynolds numbers from 40 to 10,000 was investigated in a low-speed wind tunnel. Standard hot-wire techniques were used to study the velocity fluctuations. The Reynolds number range of periodic vortex shedding

The proposed deep learning framework integrates ResNet‐50 and LSTM models to detect and classify terrestrial ecosystems from satellite imagery. The workflow begins with image preprocessing using bilateral, guided, and median filters to enhance image quality and preserve edges.

In this study, systematic experiments are conducted on a vertical rigid cylinder with two degrees of freedom in the subcritical Reynolds-number regime. The selected flow conditions cover the excitation stage, the lock-in stage, and the post-lock-in stage

On the phenomenon of vortex street breakdown
A von Kármán vortex street generated in the usual way was subjected to a deceleration, thereby changing the ratio of longitudinal to lateral spacing between the vortices. Distortion of the individual vortices followed which resulted in annihilation of concentrated vortex regions and creation of a stationary wake flow.

Numerical simulation of flow around an orbiting cylinder at different ellipticity values [PDF]
This paper deals with the numerical simulation of low Reynolds number flow (Re=120–180) past a circular cylinder in orbital motion. The Navier–Stokes equations, pressure Poisson equations and continuity are written in primitive variables in a noninertial

ABSTRACT This article examines what becomes possible for interpretive literacy research when time is treated not as a neutral backdrop but as a central problematic. We argue that research does not merely trace temporal sequences; it actively creates temporalities that shape what becomes sensible, thinkable, and sayable within literacy studies.
