The human eye is affected by large chromatic aberration. This may limit vision and makes it difficult to see fine retinal details in ophthalmoscopy. We designed and built a two-triplet system for correcting the average longitudinal chromatic aberration of the eye while keeping a reasonably wide field of view. Measurements in real eyes were conducted to examine the level and optical quality of t...

In this paper, we introduce a class C, of domains of RN , N ≥ 2, which satisfy a geometric property of the inward normal (such domains are not Lipschitz, in general). We begin by giving various results concerning this property, and we show the stability of the solution of the Dirichlet problem when the domain varies in C.

A general purpose kinetic parallel flow solver was developed based on DSMC methodology. Basic characteristics of the solver and some examples of its application are outlined in the paper.

This review starts with a brief history and description of adaptive optics (AO) technology, followed by a showcase of the latest capabilities of AO systems for imaging the human retina and an extensive review of the literature on where AO is being used clinically. The review concludes with a discussion on future directions and guidance on usage and interpretation of images from AO systems for t...

In this paper we study the asymptotic behavior for the tail probability of the randomly weighted sums and their maximum where the usual assumption of independence of random variable X and indepedence between the variable X and the weighted θ are relaxed. We suppose that, the variable X follows a conditional dependence intoduced by Geluk and Tang [6] and the pair (X, θ) follows a certain depende...

The Spanish health system has undergone spectacular development in recent decades. It now provides universal access, almost without direct costs for patients, and achieves high levels of quality and excellence. However, in parallel with other Western countries’ health systems, the Spanish system is showing signs of strain as it faces ever-greater costs as a result of the increased resources nee...

Recently, utilization of renewable resources to replace petroleum as a primary feedstock for liquid fuels, chemicals and materials has become a topic of interest around the world. It is intriguing due to rising oil prices, the negative effects of petroleum on the environment and the advantages of renewable resources, such as their abundance and sustainability. Herein, the possibilities for biob...

Zusammenfassung: Im Rahmen des Forschungsprojektes „Mediencommunity 2.0“ werden Möglichkeiten nutzerorientierter Einbindung von Web 2.0-Medien zur Verbesserung der Qualität der Anpassungsund Aufstiegsqualifizierung in der Druckund Medienbranche überprüft. Die didaktische Konzeption von Rahmenbedingungen für informelle, non-formelle und formelle Lernprozesse in der Lernercommunity verfolgt einen...
