A procedure to determine the best image range of distances that can be obtained from an aphakic eye is presented. Corneal surfaces are calculated from videokeratographic data. Light distributions at different distances inside the eye are calculated with a near-field…

In this work, we have applied the fractional Fourier transform to obtain the Fresnel diffraction patterns in a theoretical eye. The FRT approach to Fresnel diffraction is easily implemented in a Gullstrand-Emsley theoretical eye, and it allows us to obtain…

The definitive version is available at www3.interscience.wiley.com, Aim  To identify Antarctic palaeoendemic taxa and their probable glacial refugia from regional groups of endemic species records.


Location  Antarctica.


Methods  We compiled a list of Antarctic non-marine invertebrates…

In this work we have studied the influence of the gaze stabilizing movements of the eye on the quality of the retinal image of the human eye obtained by double pass methods. The results obtained agree with the expected differences…

This paper sets out to examine the impact of fiscal policy changes in a time of severe pressure on government
budgets and considers the role of the perception of taxation upon government policy formulation. The
paper discusses how perceptions of…

This paper presents a novel algorithm which registers pressure information from tactile sensors installed over the fingers of a robotic hand in order to perform manipulation tasks with objects. This algorithm receives as an input the joint trajectories of the…

In June 2007, at the Annual General Meeting in Mexico City, IASPM discussed and approved the creation of an online journal with the aim of offering an alternative to recognized academic journals, as practical confirmation that the organization is a…
