Cloud robotics is becoming a trend in the modern robotics field, as it became evident that true artificial intelligence can be achieved only by sharing collective knowledge. In the ICT area, the most common way to formulate knowledge is via the ontology concept, where different meanings connect semantically. Additionally, a considerable effort to merge robotics with assisted living concepts exists, as the modern societies suffer from lack of caregivers for the persons in need. In the current work, an attempt is made to merge a robotic and an AAL ontology, as well as utilize it in the RAPP Project (EU-FP7). © Springer International Publishing Switzerland 2015. Source

The microsampling destructions, which are caused by the sampling procedures of analytical spectroscopic methods, are, in most cases, not permitted to art objects, which are extremely valuable, rare, and fragile. Consequently, the development of nondestructive analysis techniques becomes a necessity. In this paper, we present a technique and method for the nondestructive identification of the stratigraphic structure of the paint layers of art objects. Using acoustic microscopy, in combination with time-frequency representations, the continuous or discrete wavelet transform, or the Hilbert-Huang transform, the depth profile of the stratigraphy is determined. © 2011 IEEE.

In the present study HDPE nanocomposites containing different amounts of copper nanofibers were prepared by melt mixing on a Haake-Buchler Reomixer. From SEM micrographs it was found that there is a fine dispersion of nanofibers into HDPE matrix. Tensile strength at break was unaffected from the addition of nanoparticles and only Young's modulus was enhanced. All nanocomposites in the form of thin films were exposed to UV irradiation at 280 nm for several days. As it was verified from FTIR measurements the mechanism of photo-oxidation consists of macromolecular chain scission, formation of compounds with unsaturated, hydroxyl and carbonyl end groups as well. Also, from FTIR spectroscopy and variation of mechanical properties it was concluded that the addition of Cu-nanofibers enhances the UV stability of HDPE. From acoustic microscopy it was verified that the UV degradation is an oxygen diffusion process and the addition of Cu-nanofibers delays its progress. © 2013 Elsevier Ltd. All rights reserved.

Medical advances have increased life expectancy to the point where senior citizens comprise a larger than ever percentage of the general population. The RAPP project introduces socially interactive robots that will not only physically assist, but also serve as a companion to senior citizens. In this paper, a novel system is presented, designed as part of the RAPP project that aims to assist senior citizens with mild cognitive impairment in performing cognitive tests as a means of exercise, while also keeping track of their performance. Our goal is to provide an interactive and intriguing user friendly alternative to the classic cognitive tests that will keep the patient interested and thus increase compliance. Tracking the patient's performance in the cognitive tests can prove invaluable as the data can be further associated with medical treatment or lifestyle changes and conclusively lead to better understanding of the nature of cognitive decline. © 2015 IEEE.

What really happens in terms of social inclusion and exclusion differentiates among European Countries, cultures and social groups and is being affected by socio-economic factors, social perceptions and societal changes. There are also variations among elderly in the European Union concerning their retirement from labor, institutionalization (residential or independent living), opportunities for further development or leisure and many more. A lot of EU projects focus on services that can be easy to access and affordable by elderly, enhancing the independency and autonomous living of the seniors. RAPP (EU-FP7) is addressing this need by offering a solution in the form of a software platform that will support the creation and delivery of robotic applications (RApps) targeted to people at risk of exclusion, especially older people. In this paper we are focusing to technology illiterate elderly, a group of seniors engaged for RAPP by Ormylia Foundation. © Springer International Publishing Switzerland 2015. Source
