Open educational resources for all? Comparing user motivations and characteristics across The Open University’s iTunes U channel and OpenLearn platform. [PDF]

open access: yes, 2013
With the rise in access to mobile multimedia devices, educational institutions have exploited the iTunes U platform as an additional channel to provide free educational resources with the aim of profile-raising and breaking down barriers to education ...

Automated Workflow for Phase‐Field Simulations: Unveiling the Impact of Heat‐Treatment Parameters on Bainitic Microstructure in Steel

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, OpenPhase software is used to simulate low‐carbon bainitic steels. The lower holding temperature sample exhibits smaller and finer grains. Grain thickness measurements of bainitic ferrite from simulations align with the experimental observations at high temperature. Bainitic steels are extensively utilized across various sectors, such as

Research, relativity and relevance : can universal truths answer local questions [PDF]

open access: yes, 2004
It is a commonplace that the internet has led to a globalisation of informatics and that this has had beneficial effects in terms of standards and interoperability.

Development and Validation of a One‐Dimensional Finite Difference Simulation Scheme for Polymer Laser Powder Bed Fusion with Application to the Effect of the Inter Layer Time

open access: yesAdvanced Engineering Materials, EarlyView.
The study presents an efficient simulation approach for the polymer laser powder bed fusion process polymers process, validated with polyamide 12, polyamide 6, and polyetherketoneketone. It shows that inter layer time affects part density, with 90s yielding dense parts.

Thermodynamics in Higher Dimensional Vaidya Space-Time [PDF]

open access: yesarXiv, 2012
In this work, we have considered the Vaidya spacetime in null radiating fluid with perfect fluid in higher dimension and have found the solution for barotropic fluid. We have shown that the Einstein's field equations can be obtained from Unified first law i.e., field equations and unified first law are equivalent.

Waiting for the barbarians : seeking solutions or awaiting answers? [PDF]

open access: yes, 2010
Cavafy's (1961) famous poem describes the paralysis induced when waiting for an event that never happens, finding distraction in other things while expecting imminent cataclysm.

Academic digital libraries of the future : an environment scan [PDF]

open access: yes, 2009
Libraries are attempting to face a future in which almost every fixed point has disappeared. Users are changing; content is changing; research is taking new forms. Indeed the very need for libraries is being questioned in some quarters.

A Brief History of Generative Models for Power Law and Lognormal Distributions

open access: yesInternet Mathematics, 2004
Recently, I became interested in a current debate over whether file size distributions are best modelled by a power law distribution or a lognormal distribution.

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...
