What are the technologies that will transform business and drive the research agenda for the IS field in the years to come? Which innovations, platforms, and paradigms will become dominant, and which others will ultimately pass into obscurity? In this panel discussion, we will seek answers to these questions from those with a unique and unmatched perspective. The leaders who have witnessed the ...

Almost everyone knows that the inner angles of a triangle sum to 180o. But if you ask the typical mathematician how to sum the solid inner angles over the vertices of a tetrahedron, you are likely to receive a blank stare or a mystified shrug. In some cases you may be directed to the Gram-Euler relations for higher dimensional polytopes [3, 4, 6, 7], a 19th century result unjustly consigned to ...

e nature of divine eternality is obscure in both historical andmodern discussions. In a way its obscurity is no surprise, given that the nature of time is so mysterious.

This study provides a semi-probabilistic approach to durability design of reinforced concrete structures, subjected carbonation-induced corrosion. The method was developed from an existing and using comprehensive data collated the literature. A statistical model for predicting accelerated carbonation coefficient, as input variables mix proportions test conditions also generated. performance pro...

Abstract Annual resolution sediment layers, known as varves, can provide continuous and high-resolution chronologies of sedimentary sequences. In addition, varve counting is not burdened with the high laboratory costs geochronological analyses. Despite a more than 100-year history use, many existing techniques are time consuming difficult to reproduce. We present countMYvarves, toolbox which us...
