I n recent years, many research activities have focused on design that aims to produce universally accessible systems, taking into account special needs of various user groups. These special needs are associated with many user factors, such as impairments of speech, hearing or vision, cognitive limitations, aging, as well as with various environmental factors [3]. Fields that address this probl...

This paper reviews some of the recent applications of artificial neural networks taken from various works performed by the authors over the last four years at the NASA Glenn Research Center. This paper focuses mainly on two areas. 1) Artificial neural networks application in design and optimization of aircraft/engine propulsion systems to shorten the overall design cycle. Out of that specific a...

Microfluidic systems promise solutions for high throughput and highly specific analysis for biology, medicine and chemistry while consuming only tiny amounts of reactants and space. On these lab-on-a-chip platforms often multiple physical effects such as electrokinetic, acoustic or capillary phenomena from various disciplines are exploited to gain the optimal functionality. The fluidics on thes...

abstract the theory of hardship is a situation in which the implementation of contractual obligation, as a result of unpredictable events that are out of control, becomes economically difficult and expensive without being physically impossible and distorts the balance of the contract. in such a situation, the hardship theory is applied to restore the balance of the contract. this matter has var...

It is like listening to a stewardess in a jet airliner who is explaining the safety measures: you have heard 1000 times before that the human genome has been sequenced and that a flood of data is coming over us. The question is how the massively parallel measurements of large numbers of genes, messenger RNAs, proteins and metabolites are going to help us in prognosis and diagnosis of common hum...

Networks have attracted a great deal of attention the last decade, and play an important role in various scientific disciplines. Ranking nodes in such networks, based on for example PageRank or eigenvector centrality, remains a hot topic. Not only does this have applications in ranking web pages, it also allows peer-to-peer systems to have effective notions of trust and reputation and enables a...
