decision-tree algorithms provide one of the most popular methodologies for symbolic knowledge acquisition. the resulting knowledge, a symbolic decision tree along with a simple inference mechanism, has been praised for comprehensibility. the most comprehensible decision trees have been designed for perfect symbolic data. classical crisp decision trees (dt) are widely applied to classification t...

In this paper, we aim to study how young people navigate a super-diverse majority-minority context, and they negotiate bright religious ethnic symbolic boundaries. Our is based on 40 in-depth interviews with from various ethnic, social backgrounds in the city of Antwerp. analysis shows that generally draw cultural repertoire commonplace diversity peer relations present as normal element everyda...

The study aimed to examine the developmental trajectories of non-symbolic and symbolic addition capacities in children and the mapping ability between these two. We assessed 106 4- to 7-year-old children and found that 4-year-olds were able to do non-symbolic addition but not symbolic addition. Five-year-olds and older were able to do symbolic addition and their performance in symbolic addition...

New decidability results concerning two-way counter machines and applications. 15 machine instruction that adds (or subtracts) the input variable a to the register corresponds, then, to a transition labeled with (y = a; y := 0) (or (x = a; x := 0), respectively). Transition labels of the form (x y), for 2 f=; <; >g, which correspond to test instructions, can be eliminated by duplicating each st...

Symbolic and non-symbolic number representations are thought to share common neural substrates. However, recent studies have shown that the two numerical systems are more distinct than previously thought. These disparate findings may be explained by the use of sequential presentations of symbolic and non-symbolic quantities, the use of magnitude-reliant tasks, or the use of limited number range...

This study examines the visual aesthetic function of English signs in line with ethnographic approaches as a means of achieving various symbolic and communicative implications in the linguistic landscape (LL) of Jordan. Having coded the data in 6 urban streets of the major Jordanian cities, the social semiotic analysis centers on the visual layout of signs based on the typographical features of...

Since the Sassanid era, many reliefs and seals have left and by reviewing their designs, the mythical and religious attitudes of those people can be understood. The purpose of this article is to decode and interpret the symbolic paintings and to review and study the myths, concepts, and religious rituals of this period. The question is that what the divine and human origin of the symbolic paint...

Much of the energy of the nuclei colliding at RHIC or SPS is converted into final state hadronic particles. About a quarter of this energy is in baryons and antibaryons. There are nearly 10 strange quark pairs per central rapidity participant. Do we really understand the hadronic particle yields? Do we need to introduce post-Fermi-model ideas such as chemical non-equilibrium in order to underst...

Eden is a parallel functional language extending Haskell with processes. This paper describes the implementation of an interface between the Eden language and the Maple system. The aim of this effort is to parallelize Maple programs by using Eden as coordination language. The idea is to leave in Maple the computational intensive functions of the (sequential) algorithm and to use Eden skeletons ...
