This procedure has developed the use of TiO2 nanoparticles as an environmentally friendly and highly efficient heterogenous nanocatalyst for the eco-safe, facile and one-pot three-component Biginelli synthesis of biologically active corresponding 3,4-dihydropyrimidin-2-(1H)-one/thione derivatives under solvent-free conditions. This eco-friendly protocol provi...

The promoting effect of niobium in a Li/MgO catalyst for the oxidative coupling of methane (OCM) and for the oxidattve dehydrogenation of ethane (ODHE) has been studied in some detail. it has been found that a Li/Nb/MgO catalyst with 16 wt % niobium showed the highest activity for the C, production in the OCM reaction; the activity at 600 “C was ten times that of the Li/MgO catalyst at the same...

Because of the rapid evolution of mobile and embedded computing devices, it is important for a business that its services are accessible for a large group of possible service consumers. These consumers want to gain access to the offered services from heterogeneous environments. In this context, much work has been done on the (semi-) automatic generation of user interfaces (UIs) for services tha...

This is a position paper that presents a new approach to identifying important nodes or entities in a complex heterogeneous network. We provide a novel definition of an importance score based on a statistical model: An individual is important to the extent that including an individual explicitly in the model improves the data fit of the model more than it increases the model’s complexity. We ap...

As unmanned vehicles (UVs) become increasingly autonomous, the current multiple human to single vehicle ratio is likely to be reversed in that a single human operator may direct a team of UVs at the supervisory control level. A single human operator supervising UVs in the context of a time-critical mission will require dynamic adaptation of the mission plan to account for emergent and unexpecte...

Lately, programmers have started to take advantage of GPU capabilities of cloud-based machines. Using the GPUs can decrease the number of nodes required to perform the computation by increasing the productivity per node. We combine Hadoop, a widely-used MapReduce framework, with Aparapi, a new Java-to-OpenCL conversion tool from AMD. We propose an easy-to-use API which allows easy implementatio...

Although very controversial in the field of evolutionary biology, the notion of evolutionary progress is nevertheless generally accepted in the field of Artificial Life. In this article we adopt the definition proposed by Shanahan (2012) to study the existence of evolutionary progress in an evolutionary simulation which we call HetCA. HetCA is a heterogeneous cellular automata characterized by ...

The problem of moving from one coadapted gene complex to a better one can be divided into two steps: first the advantageous combination has to appear and then it has to take over the population. Selection can have contrasting effects on the two stages. When selection is weak intermediate forms are frequent, and the advantageous combination appears easily. Spreading of that advantageous combinat...

While ontologies exist for the annotation of monomedia, interoperability between these schemes is an important issue. The OntoMedia ontology consists of a generic core, capable of representing a diverse range of media, as well as extension ontologies to focus on specific formats. This paper provides an overview of the OntoMedia ontologies, together with a detailed case study when applied to vid...

The traditional concept of a database view is currently under influence on new ideas, in particular the CORBA approach to distributed objects, objectoriented databases, XML and other Web technologies, semistructured data, and autonomous mobile agents. These new trends cause widening the scope of database views by novel features, which are beyond the current theoretical and conceptual paradigms ...
