Enhancing higher education experience: The eMadrid initiative at UNED university
(Institute of Electrical and Electronics Engineers Inc., 2015)
In this paper we focus on the achievements of eMadrid initiative in some fields of technology-enhanced learning, mainly involving the improvement of the mechanisms for open educational content retrieval from Internet, ...
Conformastationary disk-haloes in Einstein–Maxwell gravity
(Springer New York LLC, 2015)
An exact solution of the Einstein–Maxwell field equations for a conformastationary metric with magnetized disk-haloes sources is worked out in full. The characterization of the nature of the energy momentum tensor of the ...
IMMAN: free software for information theory-based chemometric analysis
(Kluwer Academic Publishers, 2015)
Abstract: The features and theoretical background of a new and free computational program for chemometric analysis denominated IMMAN (acronym for Information theory-based CheMoMetrics ANalysis) are presented. This is ...
On the illumination compensation of retinal images by means of the bidimensional empirical mode decomposition
(SPIE, 2015)
Retinal images are used for diagnostic purposes by ophthalmologists. However, despite controlled conditions in acquisition retinal images often suffer from non-uniform illumination which hinder their clinical use. In this ...
Programmable diffractive optical elements for extending the depth of focus in ophthalmic optics
(SPIE, 2015)
The depth of focus (DOF) defines the axial range of high lateral resolution in the image space for object position. Optical devices with a traditional lens system typically have a limited DOF. However, there are applications ...
Improving the blind restoration of retinal images by means of point-spread-function estimation assessment
(SPIE, 2015)
Retinal images often suffer from blurring which hinders disease diagnosis and progression assessment. The restoration of the images is carried out by means of blind deconvolution, but the success of the restoration depends ...
Assessing the significance of the correlation between the components of a bivariate Gaussian random field
(John Wiley and Sons Ltd, 2015)
Assessing the significance of the correlation between the components of a bivariate random field is of great interest in the analysis of spatial data. This problem has been addressed in the literature using suitable ...
Design of discrete event systems supported on wireless sensors and actuator networks using colored Petri Nets
(Institute of Electrical and Electronics Engineers Inc., 2015)
Manufacturing systems are highly parallel and distributed processes which require a high level of guarantee in operation and safety. Its concurrent and non-deterministic nature makes its analysis and design very complex. ...
Variational thermodynamics of relativistic thin disks
(Springer New York LLC, 2015)
We present a relativistic model describing a thin disk system composed of two fluids. The system is surrounded by a halo in the presence of a non-trivial electromagnetic field. We show that the model is compatible with the ...
A Hooke's law-based approach to protein folding rate
(Academic Press, 2015)
Kinetics is a key aspect of the renowned protein folding problem. Here, we propose a comprehensive approach to folding kinetics where a polypeptide chain is assumed to behave as an elastic material described by the ...
