All around us, the world is changing continuously, evolving every minute of the day. These changes are captured in event data that are partial snapshots of its evolution. The idea of story evolution is to combine these bits of information, reconstructing the real world and its evolution through a digital model of their relationships.

A reliable dynamic simulator (based on a sound process model) is highly desirable for optimizing the performance of individual membrane modules and of entire desalination plants. This paper reports on progress toward development of a comprehensive model of the complicated physical-chemical processes occurring in spiral wound membrane (SWM) modules, that accounts for the...

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 ...

In this paper we investigate a nonlinear evolution model described by the Rosenau-KdV equation. We propose a three-level average implicit finite difference scheme for its numerical solutions and prove that this scheme is stable and convergent in the order of O(τ2 + h2). Furthermore we show the existence and uniqueness of numerical solutions. Comparing the numerical results with other methods in...

In the observations, El Niño events initiated by a subtropical Pacific mechanism (SP-onset Niños) show larger uncertainty in their decay evolution patterns than those tropical mechanism. A 2,200-year simulation of Community Earth System Model reproduces this observed feature and its SP-onset Niños are analyzed to understand cause large uncertainty. Results that onset location Niño, which intera...

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. But the obscurity is still notable relative to the other traditional divine attributes, which are comparatively much better understood. Our perplexities regarding eternality are compounded, I will argue here, by a failure to re...

H ow do smalland medium-sized firms raise external equity capital? In this paper, I describe two markets that entrepreneurs of smalland medium-sized enterprises use in the United States to raise equity: the organized private equity market and the market for angel capital. Both markets are important sources of equity capital for smalland mediumsized firms. However, until recently, not much was k...
