Prediction of solar storms has become a very important issue due to the fact that they can affect dramatically the telecommunication and electrical power systems in the earth. As a result, a lot of research is being doing in this direction, space weather forecast. Magneto-Hydrodynamics systems are being studied in order to analyze the space plasma dynamics, and techniques which have been broadl...

A pure Silicate host namely Sr2MgSi2O7 as a support for a long-lasting afterglow when dopped with rare-earth elements was sought after. To this end the process of obtaining firing temperatures of the above mentioned phase in normal condition was carried out using suggested wet and dry methods. The degree of purity obtained in these preparatory methods as wel...

has developed a rigorous, technology-based learning environment that assists and assesses (hence, " assistments ") middle school students in Earth, Life, and Physical Science so that teachers can assess their students' skills rigorously, frequently, and in the context in which they are developing, namely, during instruction (Mislevy et al, 2002). Our program of work represents a significant adv...

This work gives a detailed analysis of the relative performance between the Earth Simulator and ASCI Q. The Earth Simulator uses vector processing nodes interconnected using a single-stage cross-bar network, whereas ASCI Q is built using superscalar Alpha microprocessors and the Quadrics Elan3 interconnection network. The performance that can be achieved on a system results from an interplay of...
