a individuated by their constituent properties, where the constituent properties are those the subject is inclined to predicate on the strength of his hallucination.38 Charles, who starts out as real and then is evidently unreal, (if I may put it that way) is not to be found among such this-worldly abstracta. Once again, even an abstract entity that includes the property of being first real and...

This paper presents a virtual manipulation environment dealing with elastic objects. An original fast computation elastic model ‘the gradational resolution model’ is introduced for real-time interaction, in which the number of elastic elements are efficiently reduced for acceleration. Joystick force feedback is used for sensible interaction. Two kinds of collision algorithms are examined by joy...

In this paper I make the arguments that I see supporting a view of how we can come to know the world we live in. I start from a position in second order cybernetics which turns out to be a Radical Constructivist position. This position is essentially epistemological, and much of this paper is concerned with the act of knowing, crucial when we try to develop an understanding of what me mean when...

In this paper, a novel multi-objective bus stop location model is proposed, which considers not only the coverage of demand and minimization of access time but also the necessities of suitable stops for transit network design phase. Three objective functions are considered including minimizing (I) sum of the total access distance (time), (II) the weighted combination of stops, and (III) the num...
