This paper presents an efficient approach to address the task of learning from large number of learning examples in structural domains. While in attribute-value representations only one mapping is possible between descriptions, in first order logic representations there are potentially many mappings. Classic approaches consider all mappings and then define a restricted hypothesis space to cope ...

When dealing with pairwise comparisons of stimuli in two fixed observation areas (e.g., one stimulus on the left, one on the right), we say that the stimulus space is regular well-matched if (1) every stimulus is matched by some stimulus in another observation area, and this matching stimulus is determined uniquely up to matching equivalence (two stimuli being equivalent if they always match or...

In a graph, perfect matching cut is an edge that matching. (pmc) the problem of deciding whether given graph has cut, and known to be NP-complete. We revisit show pmc remains NP-complete when restricted bipartite graphs maximum degree 3 arbitrarily large girth. Complementing this hardness result, we give two classes in which polynomial-time solvable. The first one includes claw-free without ind...

the introductory issue of the journal of financial research contains six articles in farsi and one in english. it also offers a glossary of financial terminology. the first article deals with the efficient capital market hypothesis , and is authored by dr. ali jahankhani & hussein abdoh tabrizi. it explains the concept and theories of capital market efficiency and their historical development i...

The Chinese government implemented the One Child Policy in an attempt to stave off population explosion and its potential negative economic consequences on their infant economy in 1979. This article examines the consequences of this policy on marital matching and family size decisions. Using a simple General Equilibrium model, we show how by constraining marital output on the quantity of childr...

Aggressive encounters between animals often involve significant amounts of signalling before or in lieu of physical fights. When, as is often the case, these apparent threat signals are neither inherently costly nor inherently indicative of fighting ability, we should ask whether they are in fact honest signals, i.e. do they predict that escalation is imminent? While signalling theories have in...

This paper reports on a study the use of default strategy by Broca’s aphasic patient during speech comprehension using sentence to picture matching test. The test was undertaken at National Stroke Association Malaysia (NASAM), Petaling Jaya, Malaysia. current employs theory Grodzinsky’s (1990) Trace Deletion Hypothesis (TDH) as an explanation for Broca patient’s ability comprehend active and pa...

Bounded context switching (BCS) is an under-approximate method for finding violations to safety properties in shared-memory concurrent programs. Technically, BCS is a reachability problem that is known to be NP-complete. Our contribution is a parameterized analysis of BCS. The first result is an algorithm that solves BCS when parameterized by the number of context switches (cs) and the size of ...

Road safety research, in particular road and traffic safety evaluation research, is highly applied and carried out mostly to help reducing the number of road accidents and the injuries resulting from them. This subject has been continuously studied, and in developed countries road safety is improved in a way that, more and more, new measures have less visible impact. Although measures are usual...
