1 I n t r o d u c t i o n Intelligent agents must gather information about the world, elaborate theories about it and revise those theories in view of new information that , sometimes, contradicts the beliefs previously held. Belief revision is therefore a central topic in Knowledge Representation. It has been studied in different forms: numeric or symbolic, procedural or declarative, logical o...

1. The first indication of the phenomenon.-When we consider a fluid mass in equilibrium, for example, some water in a glass, all the parts of the mass appear completely motionless to us. If we put into it an object of greater density it falls and, if it is spherical, it falls exactly vertically. The fall, it is true, is the slower the smaller the object; but, so long as it is visible, it falls ...

In reply to a problem of Jean Leray (application of the Nielsen theory to differential equations), two main approaches are presented. The first is via Poincaré’s translation operator, while the second one is based on the Hammerstein-type solution operator. The applicability of various Nielsen theories is discussed with respect to several sorts of differential equations and inclusions. Links wit...

In the 1960s and 1970s, a number of researchers (including ourselves) involved in the study of cardiovascular pathophysiology and particularly in the development of techniques to quantify blood flow, came across the observation that, along with vessel diameter, also blood viscosity plays an important role not only in theory but also in practice. Until then, viscosity was thought to play only a ...

Editor’s Message In his Critique of Pure Reason (1929, Palg rave; http://www.arts.cuhk.edu.hk/ Philosophy/Kant/cpr), Immanuel Kant showe d how it can be that all our knowledge begins with experience, yet in order to mak e sense of those experiences we must know other things first. He focused especi ally on the fact that we frame experiences in space and time but cannot deriv e the ideas of spac...

Memory is not like a tape recorder or a camera or even like computer memory, we Schema theory: People mold memories to fit information that already exists in their Jean Mandler argues that early categorizations are best described.
