In June 2011, the major search engines (Bing, Google, Yahoo! and Yandex) announced the new innovation of schema.org. However, there is a clear need to integrate Virtual Learning Environments (VLEs) with the wider Web and maintain its learning contents freely open in order to support the sharing and reuse of learning resources. This paper focuses on our proposal to schema.org by proposing new vo...

We propose a novel knowledge management system KMS for enterprises. Our system exploits two different approaches for knowledge representation and reasoning: a documentbased approach based on data-driven creation of a semantic space and an ontology-based model. Furthermore, we provide an expert system capable of supporting the enterprise decisional processes and a semantic engine which performs ...

In internal combustion engines, only about a third of the total fuel input energy is converted into useful work. If the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. The main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing ce...

This thesis looked at the effect of clay and silt soil blocking the heat transfer area of the radiator and its effect on the engine coolant through the conduct of experiments and a mathematical model developed. The results indicated that the percentage area covered resulted in a proportional increase of the inlet and outlet temperatures of the coolant in the radiator. The mathematically mode...

Basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. Coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. An efficient approach to studying cooling system for diesel engine is a 3D computational fluid dynami...
