Yeakel et al. present an innovative examination of Egypt’s ecological history (1), in which they rely upon paleontological evidence and artistic representations of animals to reconstruct patterns of species extinctions over six millennia. Focusing on ungulates and their mammalian predators, and drawing upon mammalogist Dale Osborn’s 1998 volume, The Mammals of Ancient Egypt (2), Yeakel et al. (...

In this work at the first step calcium hydroxide nano-particles were synthesized via sono-chemical method at room temperature. At the second step aminated multi-walled carbon nano-tubes was prepared via chemical modification of surfaces of CNT. Finally modified-MWCNT and Ca(OH)2 were added to paraloid matrix by aid of ultrasonic irradiation. Paraloid-modified-MWCNT-Ca(OH)2...

This paper is about simulating the spread of opinions in a society and about finding ways to counteract that spread. To abstract away from potentially emotionally laden opinions, we instead simulate the spread of a zombie outbreak in a society. The virus causing this outbreak is different from traditional approaches: it not only causes a binary outcome (healthy vs infected) but rather a continu...

A cultural algorithm, together with a set of new operators for the timetabling problem(TP), is proposed in this paper. The new operators extract information about the problem during the evolutionary process, and they are combined with some previously proposed operators, in order to improve the performance of the algorithm. The proposed algorithm is tested with a benchmark of 20 instances, and c...

—Evolutionary computation is a generic term used to make reference to the solution of computational problems planned and implemented based on models of an evolutionary process. Most of the evolutionary algorithms propose biological paradigms, and the concepts of natural selection, mutation and reproduction. However, other paradigms that can be adopted in the creation of evolutionary algorithms ...

We studied a complete Holocene sediment record from shallow (zmax = 9.7 m) Lake Harris, Florida (USA) to infer the historical development of the lake and its current eutrophic status. We used (210)Pb and (14)C to date the 5.9-m sediment sequence (core LH-6-13) and determined accumulation rates for bulk sediment, organic matter, calcium carbonate, phosphorus fractions and biogenic silica fractio...

Many problems involve not structured environments which can be solved from the perspective of Bioinspired Algorithms (Cultural Algorithms). In this paper, a proposed algorithm is used to resolve a famous game known as Japanese puzzles, which are analyzed for obtain the optimal solution. The authors show that Japanese Puzzles are constrained combinatorial optimization problems, which can be solv...

Memetic Theory in Artificial Systems and Societies (METAS) is the first edition of a series of international symposia dedicated to qualitative and quantitative aspects of memetic research as applied to artificial (and natural) systems and societies. This symposium will bring together researcher working at the cutting-edge of memetic theory, cultural algorithms and the transmission of culture-li...

Classification rule mining is a class of problems which is the most sought out by decision makers since they produce comprehensible form of knowledge. The user should be ready to specify the properties of the foundations. The foundations discovered should have a number of these properties to render them helpful. This work proposes to enhance the cultural algorithm by application of ANT clusteri...
