Considerable investment has been made to bring technology to schools and these investments have indeed resulted in many “success stories.” However there are two significant gaps in educational uses of technology that must be addressed. The first is a usage gap. Compared to how and how much today’s students use technology outside school, in-school technology usage is much less intensive and exte...

given a mapping $f:xto x$ we naturally associate to it a monotonic map $gg_f:exp xto exp x$ from the power set of $x$ into itself, thus inducing a generalized topology on $x$. in this paper we investigate some properties of generalized topologies which are defined by such a procedure.

a. Mathematical upscaling: derivation of coarse-scale equations directly from atomistic equations using Generalized Mathematical Homogenization theory (Fish, Chen, Li, 2007). b. Computational upscaling: reducing the complexity of solving an atomistic problem to a manageable size that can be adapted based on available computational resources. Our model reduction approach is based on the space-ti...

Boundary objects are artefacts that reside in the interface between communities and are capable of bridging assumed and experienced differences. Bridging is not, however, necessarily neutral or consensual activity. With an emphasis on documents, the present paper discusses the politics of boundary objects by analysing the role of archaeological reports at boundaries between communities with con...

An algorithm for non-intrusively coupling a commercial finite element software with a research code implementing a hierarchical enrichment of finite element spaces is presented. Examples of hierarchical methods supported by the algorithm are the Generalized or eXtended FEM (GFEM), the scale-bridging GFEM with numerically defined enrichment functions (GFEMgl), and the p-version of the FEM. The p...

Categorization axioms have been proposed to axiomatizing clustering results, which offers a hint of bridging the difference between human recognition system and machine learning through an intuitive observation: an object should be assigned to its most similar category. However, categorization axioms cannot be generalized into a general machine learning system as categorization axioms become tr...

a number of redox-active coordination polymers (cps) or metal-organic frameworks (mofs) have been successfully synthesized using transition metals and bridging ligands. this article aims to deal with gathering the aforementioned disperse issues regarding the electroactive cps. it also goes towards illustrating the effects of various factors on the electrochemical behavior of cps including natur...

The effect of dehydration on the coordination and speciation of sulfate at the Fe-(hydr)oxide-H2O interface was investigated using molecular orbital/density functional theory (MO/DFT) and Fourier transform infrared (FTIR) spectroscopy. IR frequency calculations were performed at the UB3LYP/6-31+G(d) level of theory for potential sulfate (bidentate bridging, monodentate, and H-bonded) and bisulf...
