Emerging ExG-based NUI Inputs in Extended Realities: A Bottom-up Survey

Bottom-Up Query Evaluation in Extended Deductive Databases

Bottom - Up Query Evaluation in Extended Deductive Databases

Semantics Many concrete semantics have been defined by selecting either a specific model of every logic program (such as the well-founded model) or a set of models (such as the stable models). Furthermore, also semantics which define a program completion comp(P ), simply select a subset of the models of P by adding formulas to P . So it seems that the following definition is very wide: Definiti...

Mobile augmented reality survey: a bottom-up approach

Augmented Reality (AR) is becoming mobile. Mobile devices have many constraints but also rich new features that traditional desktop computers do not have. There are several survey papers on AR, but none is dedicated to Mobile Augmented Reality (MAR). Our work serves the purpose of closing this gap. The contents are organized with a bottom-up approach. We first present the state-of-the-art in sy...

Composition and Decomposition of Extended Multi Bottom-Up Tree Transducers?

Extended multi bottom-up tree transducers are de ned and investigated. They are an extension of multi bottom-up tree transducers by arbitrary, not just shallow, left-hand sides of rules; this includes rules that do not consume input. It is shown that such transducers can compute all transformations that are computed by linear extended top-down tree transducers (which are a theoretical model for...
