The main focus of this paper is to show the concepts, architectures, interaction techniques, and general approaches to the analysis and specification of a multi-agent system for the making of intelligence and interactive decisions inside the learner's learning process. These…

In this paper, we present a new approach for the estimation of Markov decision processes based on efficient association rule mining techniques such as Apriori. For the fastest solution of the resulting association-rule based Markov decision process, several accelerating procedures…

Two bis crown ether receptors were synthesized and tested as host molecules for protonated forms of alkyl amines and amino acid esters. Molecular recognition studies were conducted in CH2Cl2:MeOH (92:8) by spectrophotometric UV/Vis titrations and by spectrometric ¹H NMR titrations…

Vinylcyclopropane and bicyclopropyl C6 compounds are studied as diene precursors in the Diels-Alder reaction. Their rearrangement under different thermal and microwave conditions leads to specific isomeric hexa-, penta- or butadienes, condensed with maleic anhydride as a dienophile. Adduct stereochemistries were…

A chemical study of Psacalium sinuatum afforded the furanoeremophilane decompostine, the modified eremophilanes: cacalol, cacalol acetate, dehydrocacalol, maturinin, cacalohastin, dehydroca-calohastin, adenostin B, cacalone-epi-cacalone mixture, dimaturin, adenostylide, radulifolin F, and epi-radulifolin F, in addition to hyperin, sucrose and a mixture of…

Density functional theory and molecular dynamics were used to study the adsorption of CO on a graphene layer modifie with high titanium coverage (C2Ti) at atmospheric pressure and 300 K. We found that the CO molecule is adsorbed and dissociated.

The diurnal weevil Optatus palmaris Pascoe was found on Annona muricata L. (Anonaceae) fruits in Nayarit, Mexico which represents a new plant host record and extends the weevil distribution. Other plant hosts and damages produced are mentioned.
