This paper presents an approach for collaboration in modeling that builds on ideas of Concern-Oriented Reuse (CORE). CORE is a novel reuse paradigm that supports broad-based model reuse. We leverage the ideas of CORE and version control systems to support collaborative modeling of reusable concerns. We capture our ideas in a metamodel and demonstrate our approach by collaboratively modeling a d...

Much of the previous work on hand-eye coordination has emphasized the reconstructive aspects of vision. Recently, techniques that avoid explicit reconstruction by placing visual feedback into a control loop have been developed. When properly deened, these methods lead to calibration insensitive hand-eye coordination. In this article, recent work on projective geometry as applied to vision is us...

In this article, we propose a new paradigm of control, called a maximum-hands-off control. A hands-off control is defined as a control that has a much shorter support than the horizon length. The maximum-hands-off control is the minimum-support (or sparsest) control among all admissible controls. We first prove that a solution to an L-optimal control problem gives a maximum-handsoff control, an...

background: iran is one of the countries that has ratified the world health organization framework convention of tobacco control (who-fctc), and has implemented a series of tobacco control interventions including the comprehensive tobacco control law. enforcement of this legislation and assessment of its outcome requires a dedicated evaluation system. this study aimed to develop a generic model...
