Until recently, the interaction between environmental quality, economic activity and growth is predominantly considered in an a-spatial context. Traditional neoclassical growth theor y following Solow/Swan has mainly addressed questions about environmental and resourc e limits to growth. Recently, much attention is also devoted to the environment-growth interface from an endogenous growth persp...

The PRC Adaptive Knowledge-based Text Understanding System (PAKTUS) has been under development as a n Independent Research and Development project at PRC since 1984 . The objective is a generic system of tools , including a core English lexicon, grammar, and concept representations, for building natural language processin g (NLP) systems for text understanding. Systems built with PAKTUS are int...

With the advancement of new communication and virtualization technologies, various tools and models have been proposed for enabling effective management of the e-collaboration processes related to the creation, sharing, and presentation of collective knowledge. In the theoretical perspective, two significant aspects of collaborative knowledge management have been considered: (a) the internal pr...

There have been major advances in the care of preterm infants. Reduction in mortality among very low birth weight infants has lead to a rise in the number of survivors with severe handicaps. The understanding of preterm labour has evolved, leading to a significant change in the management of preterm labour. Despite this, infection still remains a major cause of preterm delivery. In our review w...

Qualitative models provide the domain knowledge for qualitative reasoning systems, and the automatic generation of such models is an important knowledge acquisition task . Qualitative Simulation is a key qualitativ e reasoning technique . It is proposed that simulation systems like Kuipers ' QSIM [Kuipers 86] contain a powerful description language, based as they are on qualitativ e mathematics...

The formation and dissociation of specific noncovalent interactions between a variety of macromolecules play a crucial role in the function of biological systems. During the last few years, three main lines of research led to a dramatic improvement of our understanding of these important phenomena. First, combination of genetic engineering and X ray cristallography made available a simultaneous...

Purpose: The objective of this study was to identify the profile academic research on blended learning in world and propose a agenda for topic. Theoretical framework: Local governance is important advancing SDGs, but how realistic it that public private actors at local levels will take challenge spurring action achieve SDGs rather than relying international organizations national governances. R...

This paper reports a numerical investigation of the transcritical droplet vaporization phenomena. The simulation is based on the time-dependent conservation equations for liquid and gas phases, pressure-dependent variable thermophysical properties, and a detailed treatment of liquid-vapor phase equilibrium at the droplet surface. The numerical solution of the two-phase equations employs an arbi...

There is a growing need to combine information from multiple existing knowledge bases for unanticipated uses, and to maintain such information when the underlying knowledge bases change. The autonomy of diverse knowledge sources is an obstacle to integrating all pertinent knowledge within a single knowledge base. The cost of maintaining integrated knowledge within a single knowledge base grows ...
