Computational models of creative design typically adopt a specific mechanism and apply that mechanism to a design space to demonstrate its potential for generating creative designs. For example, some computational models use analogy as a reasoning mechanism for developing novel designs from previous designs and others use evolutionary algorithms as a way of searching the design space to get to ...

In this paper, we provide formal definitions for object space, space subdivision and ray tracing. We also introduce concept models such as ordered space subdivisions and ordered visualization. From these works, we can evaluate the correctness and performance of our space subdivision scheme for volume visualization. With these definitions, we also analyze some established space subdivision appro...

We present spectral graph skeletons (SGS), a novel graphbased method for action recognition from depth cameras. The contribution of this paper is to leverage a spectral graph wavelet transform (SGWT) for creating an overcomplete representation of an action signal lying on a 3D skeleton graph. The resulting SGS descriptor is efficiently computable in time linear in the action sequence length. We...

The inversion of schema mappings has been identified as one of the fundamental operators for the development of a general framework for metadata management. In fact, during the last years three alternative notions of inversion for schema mappings have been proposed (Fagin-inverse [10], quasi-inverse [14] and maximum recovery [2]). However, the procedures that have been developed for computing t...

The SGS risk management process is implemented in full compliance with international standards e. g. ISO 31000, as a minimum requirement. The SGS team is committed to improving the delivery of risk management in terms of statistical processes, facilitated workshops for identification and assessment, development of better graphical communications of risk, more calibrated assessments, off-setting...

OBJECTIVE This review synthesizes communication interventions that involved the use of speech generating devices (SGD) for individuals with developmental disabilities. METHODS Systematic searches of electronic databases, journals and reference lists identified 35 studies meeting the inclusion criteria. These studies were evaluated in terms of (a) participants, (b) SGD function, (c) SGD charac...

The notion of generating functions of Poisson structures was first studied in [2]. They are special functions which induce, on open subsets of R, a Poisson structure together with the local symplectic groupoid integrating it. A universal generating function was provided in terms of a formal power series coming from Kontsevich star product. The present article proves that this universal generati...

We consider the job-shop problem with sequence-dependent setup times. We focus on the formal definition of schedule generation schemes (SGSs) based on the semi-active, active, and non-delay schedule categories. We study dominance properties of the sets of schedules obtainable with each SGS. We show how the proposed SGSs can be used within single-pass and multi-pass priority rule based heuristic...

We present new algorithms for permutation group manipulation. Our methods result in an improvement of nearly an order of magnitude in the worst-case analysis for the fundamental problems of finding strong generating sets and testing membership. The normal structure of the group is brought into play even for such elementary issues. An essential element is the recognition of large alternating com...
