Seeing and describing real and imaginary three-dimensional scenes from the observer’s viewpoint is an intuitive activity for non-impaired people, but it is difficult for congenitally blind people, once it involves abstract concepts for them, such as: perspective, depth planes, occlusion, etc. This paper discusses the problem related to understanding three-dimensional concepts by blind people an...

The statistical analysis of discrete data has been the subject of extensive statistical research dating back to the work of Pearson. In this survey we review some recently developed methods for testing hypotheses about high-dimensional multinomials. Traditional tests like the χ-test and the likelihood ratio test can have poor power in the high-dimensional setting. Much of the research in this a...

in today's communities achieving to effectiveness of urban advertising is one of troubles of advertisement industry. this research is trying to answer this question that using three-dimensional design in urban advertising has what place in urban field? this query has been conducted in the method of iconological analysis on chosen urban advertising works of last 15 years in the world with t...

The discussion of models and modeling in this chapter is based, in part, on the results of research on students’ understanding of quantum mechanics (Gardner, 2002) and research designed to probe students’ ability to visualize the rotation of organic molecules (Briggs, 2004). Our perspective on models and modeling has also been influenced by work in both physics education (Halloun, 1996) and mat...

Continuity and change is a core biology theme that refers to how genetic information is carried forward. This paper reports on our initial steps toward representing this core theme in an existing knowledge base and describes the methodological background and open challenges. We define continuity and change from a conceptual modeling perspective, identify its facets that require further ontologi...

Co-simulation is a key tool in the design and operation of a growing number of complex cyber-systems. But efficiently yet accurately combining continuous time components (such as FMUs) with event-based ones can be challenging, both from a modeling perspective and an operational, tools-oriented one. We propose a platform to tackle this problem building up on MECSYCO, a MAS-based DEVS wrapping pl...

Recent database research has given much attention to the specification of "flexible" transactions that can be used in interoperable systems. Starting from a quite different angle, Business Process Modelling has approached the area of communication modelling as well (the Language/Action perspective). The main goal of this paper is to provide some useful structuring mechanisms for interoperable t...
