We introduce a family of preferential logics that are useful for handling information with different levels of uncertainty. The corresponding consequence relations are nonmonotonic, paraconsistent, adaptive, and rational. It is also shown that the formalisms in this family can be embedded in corresponding four-valued logics with at most three uncertainty levels, and that reasoning with these lo...

I have two main aims. The first is general, and more philosophical (§2). The second is specific, and more closely related to physics (§§3 and 4). The first aim is to state my general views about laws and causation at different 'levels'. The main task is to understand how the higher levels sustain notions of law and causation that 'ride free' of reductions to the lower level or levels. I endeavo...

Reuse of models assists in constructing a new model on the basis of existing knowledge, by retrieving a model that matches a preliminary partial input model. It often employs similarity measures for identifying reusable models that are structurally and semantically similar to the input model. However, in many cases the preliminary input model is of a higher level of abstraction than the detaile...

Previous category learning research and the SUSTAIN (Supervised and Unsupervised STratified Adaptive Incremental Network) model of category learning suggest that preferred category level (in a hierarchy of categories) shifts towards lowerlevel (i.e., more specific) categories when stimuli are perceived to be more distinctive. This shift is in accord with work in expertise. In their domain of ex...

in this paper the response modification factor due to ductility and saved strength of cylindrical concrete elevated and ground tanks is obtained using finite element method and nonlinear push over analysis considering the lateral effective modes of tanks. to modeling the behavior of the tank materials, the five parameters william-warnke and prefect elastoplastic models are used for concrete and...

Classification and recognition of human activity is an important field od computer vision based human motion analysis. The main problem of human motion analysis is the great complexity of human motion, which is rooted in the complicated structure of human body itself. In this paper we explore an alternative view of human motion analysis, which is based on the concept of human motion scale. This...
