Heun Functions and Some of Their Applications in Physics

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
Most of the theoretical physics known today is described by using a small number of differential equations. For linear systems, different forms of the hypergeometric or the confluent hypergeometric equations often suffice to describe the system studied.

Optimized Reputable Sensing Participants Extraction for Participatory Sensor Networks

open access: yesMathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014
By collecting data via sensors embedded personal smart devices, sensing participants play a key role in participatory sensor networks. Using information provided by reputable sensing participants ensures the reliability of participatory sensing data.

From Physics Model to Results: An Optimizing Framework for Cross‐Architecture Code Generation

open access: yesScientific Programming, Volume 21, Issue 1-2, Page 1-16, 2013., 2013
Starting from a high‐level problem description in terms of partial differential equations using abstract tensor notation, the Chemora framework discretizes, optimizes, and generates complete high performance codes for a wide range of compute architectures. Chemora extends the capabilities of Cactus, facilitating the usage of large‐scale CPU/GPU systems

A conceptual analysis of Julian Barbour's time [PDF]

open access: yes, 2011
One of Julian Barbourâ s main aims is to solve the problem of time that appears in quantum geometrodynamics (QG). QG involves the application of canonical quantization procedure to the Hamiltonian formulation of General Relativity.

Quantum Gravity: Motivations and Alternatives [PDF]

open access: yes, 2009
The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quantum Gravity.

Under-determination in Cosmology: an Invitation [PDF]

open access: yes, 2012
I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions.

Spacetime and the Philosophical Challenge of Quantum Gravity [PDF]

open access: yes, 2001
We survey some philosophical aspects of the search for a quantum theory of gravity, emphasising how quantum gravity throws into doubt the treatment of spacetime common to the two `ingredient theories' (quantum theory and general relativity), as a 4 ...

Brane-World Gravity [PDF]

open access: yes, 2010
The observable universe could be a 1+3-surface (the “brane”) embedded in a 1+3+d-dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.

Moderate structural realism about space-time [PDF]

open access: yes, 2006
This paper sets out a moderate version of metaphysical structural realism that stands in contrast to both the epistemic structural realism of Worrall and the – radical – ontic structural realism of French and Ladyman.
