Increasing material’s strength has been a significant matter since the beginning of engineering to up to now. It has always been paid attention by engineers. A variety of methods has been presented for increasing strength, stability, working range and material working life by development of engineering sciences and more identification on material properties and the material behavior, which are ...

A brief overview of formation method of flexible learning objects is presented in this article. The basis of this method is e-learning material that is structured and separated from display rules. The learning objects that have such e-learning material may be adapted to individual needs and may be used in different learning contexts without changing e-learning material. To change the presentati...

Course material for electronic learning environments is often structured using ontology and schema languages. During the specification and development of course material, many mistakes and errors can be made. In this paper we introduce schema-analysis as a technique to analyse structured documents, and to point out (possible) mistakes introduced by an author during authoring. With this techniqu...

The effects of an advance organizer, a preview of text structure and two arrangements of text material on prose learning and delayed retention were investigated. Text material was preceded by either an advance organizer, a preview of structure, or a neutral control passage. Two text structures were developed: 1) a hierarchical structure; 2) a hierarchical and categorical structure. Subjects wer...

Copper vanadate nanostructures were prepared via ex-situ precipitation approach in presence of Schiff-base ligand (N,N׳ -buthylenebis(acetylacetone iminato)dianion = acacbn) as a new capping agent. The effect of different Cu sources and pH on the size, morphology and size distribution of copper vanadate nanostructures was investigated. The as-prepared products were characterized using X-ray dif...

A prerequisite for joining the rapidly growing Semantic Web is to expose data as RDF triples. In the cultural heritage world the data in question is very often a mixture of structured database fields and associated textual documents. Transforming relational database (RDB) content to RDF is not altogether straightforward and the issues are examined as a preliminary to the much more difficult ste...

Working memory (WM) performance in humans can be improved by structuring and organizing the material to be remembered. For visual and verbal information, this process of structuring has been associated with the involvement of a prefrontal-parietal network, but for non-verbal auditory material, the brain areas that facilitate WM for structured information have remained elusive. Using functional ...
