In the literature, different axiomatizations of Public Announcement Logic (PAL) were proposed. Most of these axiomatizations share a ‘core set’ of the so-called reduction axioms. In particular, there is a composition axiom which stipulates how two consecutive announcements are composed into one. In this paper, by designing non-standard Kripke semantics for the language of PAL, we show that with...

A rst order system, PAL, that can learn Chess patterns in the form of Horn clauses from simple example descriptions and general purpose knowledge about Chess is described. This is the rst time that Chess patterns which can be used for over-the-board play have been learned. To test if the patterns learned by PAL can be used to play, a simple playing strategy for the King and Rook against King (K...

The Writing Pal (W-Pal) is an intelligent tutoring system that was developed to improve students’ writing proficiency; however, it remains relatively unclear whether and how this system promotes self-regulated learning. In previous studies, we have begun to investigate the characteristics of students’ self-assessments, as well as whether interactions with W-Pal can lead to more accurate self-as...

Public announcement logic (PAL) is a paradigm case of dynamic epistemic logic, which models how agents’ epistemic states change when pieces of information are communicated publicly. PAL extends epistemic logic with the operator [A], where the intended reading of [A]φ is “After a public announcement that A, φ holds.” This logic has recently received two improvements. One improvement, studied in ...

Surender Pal Joshi one of the finest artist India. Who was very much established in his field. He had own style for art works and that is why he also known as an experimentalist, always ready to come up with new experiments. His hold a wonderful charm everyone who sees them, tends get mesmerized. born year 1958 village close Dehradun. did primary secondary education from Dehradun itself. After ...

Peer assisted learning (PAL) is well documented in the medical education literature. In this paper, the authors explored the role of PAL in a graduate entry medical program with respect to the development of professional identity. The paper draws on several publications of PAL from one medical school, but here uses the theoretical notion of legitimate peripheral participation in a medical schoo...

Embedded control systems are today created using tools that give insufficient support for rapid prototyping and code reuse. New tools for implementation of embedded controllers are necessary. This paper presents a software framework for implementation of embedded control systems. The PAL language is presented. PAL is designed to support implementation of control algorithms in particular. A run-...
