Summary Some molecular photoisomers can be isomerized to a metastable high-energy state by exposure light. These molecules then thermally or catalytically converted back their initial state, releasing heat in the process. Such reversible photochemical process has been considered for developing solar thermal (MOST) systems. In this review, we introduce concept, criteria, and state-of-th...

We propose to apply classical development methodologies to the design and implementation of Lexical Databases(LDB), which embody conceptual and linguistic knowledge. We represent the conceptual knowledge as an ontology, and the linguistic knowledge, which depends on each language, in lexicons. Our approach is based on a single language-independent ontology. Besides, we study some conceptual and...

As successful organizations recognize that they need to convert their intellectual resources into customized services, the value of electronic collaboration has increased. Current efforts in managing knowledge have concentrated on producing; sharing and storing knowledge while business problems require the combined use of these intellectual resources to enable organizations to provide innovativ...

About 60% of a companies corporate knowledge is said to be inside peoples heads. Sharing experience and knowledge in companies is unstructured today. Networks of people have proven to be efficient both within organisations and within groups of people sharing the same interest, profession etc. We propose an computer aided approach where experience and knowledge is the core, and by refocusing fro...

We propose to apply relational databases (RDB) development methodologies to the design of lexical databases (LDB), which embody conceptual and linguistic knowledge. We represent the conceptual knowledge as an ontology, and the linguistic knowledge, which depends on each language, in lexicons. Our approach is based on a single languageindependent ontology. Besides, we study some conceptual and l...
