introduction: it was often believed that countries with natural resource abundance would undergo the process of development with a more accelerated pace in comparison to other countries. the experimental results, however, demonstrate a higher rate of success for countries which lack the said resources. the paradoxical effects of the possession, or a lack there of, natural resources on different...

The purpose of this paper is to give a theoretical description of clockcharts, and their implementation in the StateClock tool for COSC4352 students. 1.0 Temporal logic and fair transition systems In the sequel, we use relative quantification where Q is a quantifier (e.g. ∀ or ∃), T is the type of the dummy variable x, R is the range of the dummy variable and P a predicate [Gries, 1993 #369]. F...

In this paper we present sQueezeBF, an effective preprocessor for QBFs that combines various techniques for eliminating variables and/or clauses. In particular sQueezeBF combines (i) variable elimination by Q-resolution and equality reduction, and (ii) clause simplification via subsumption and self-subsumption resolution. The experimental analysis shows that sQueezeBF can produce significant re...

This work addresses the problem of rule learning from simple robot experiences like approaching or passing an object. An experience is a sequence of predicates computed by a perceptual system. A difficult problem encountered in this domain by rule induction algorithms is that of noise, not only in the classification of the examples, but also in the facts describing them. Due to perceptual limit...

Recently, arithmetic coding has attracted the attention of many scholars because of its high compression capability. Accordingly, this paper proposed a Joint Source-Cryptographic-Channel Coding (JSCC) based on Arithmetic Coding (AC). For this purpose, embedded error detection arithmetic coding, which is known as continuous error detection (CED), is used. In our proposed method, a random length ...
