Density functional theory ,(DFT) calculations have been performed to investigate the properties ofcarbon decorated (C-decorated) models of boron nitride (BN) nanocones. To this aim, the apex andtip of nanocone have been substituted by the carbon atoms to represent the C-decorated models. Theresults indicated that dipole moments and energy gaps could reveal the effects of C-decorations onthe pro...

This paper describes an approach to use embedded descriptions of agent actions in task ontologies and agent communication messages compliant to FIPA ACL [4, 5]. Ontological terms denoting actions are extended with semantical descriptive decorations in such a way that an agent requested to perform a well defined action is able to extract the formal description of the activity bound to this actio...

The design of a pumpkin thrower was assigned to three Mechanical Engineering Technology students as a project for senior level "ETME 475 Mechanical Systems Design" course. As a first step, each student worked on their own pumpkin thrower. During the final phase, students worked on the design and manufacturing of the different parts of the project. During the early Fall semester one student, wit...

A new synthesis of 3H-pyrimidin-4-ones, characterized by four different sets of decorations, is presented. The strategy is based on the synthetic elaboration of readily available α-substituted β-ketoesters that, upon transformation into the corresponding acyl enamines, have been cyclized to give 6H-1,3-oxazin-6-ones. These reactive intermediates have been in turn cleanly converted into highly f...

A structure model of atoms of two sizes, interacting with Lennard-Jones potentials and simulated by molecular dynamics, was observed to freeze into a decagonal quasicrystal dominated by Frank-Kasper coordination shells and closely related to the Henley-Elser model for icosahedral quasicrystals. Idealized structure models can be described as decorations of triangle-rectangle and rhombus tilings....

The analysis of the contents of 690 children’s drawings of the den­ t is t ’s o ffice was carried out w ith the aim of determ ining the presence of »fear-inducing« and »encouraging« elements in these drawings. The results showed that only 9% of children drew encouraging elements like flowers, pictures, decorations, etc. The presence of fear-inducing elements appea­ red to depend on: 1) children...
