The paper describes the research activities conducted on the 13 century Rognosa tower in San Gimignano (Siena, Italy), the historic town inscribed on the Unesco World Heritage List in 1990. A structural nonlinear analysis of the tower has been performed via the freeware finite element code NOSA. The finite element mesh of the tower has been generated using a three-dimensional digital model of t...

Some of the algorithms for solving the Tower of Hanoi puzzle can be applied “with eyes closed” or “without memory”. Here we survey the solution for the classical tower of Hanoi that uses finite automata, as well as some variations on the original puzzle. In passing, we obtain a new result on morphisms generating the classical and the lazy tower of Hanoi, and a new result on auomatic sequences.

The fog entered and escaped through the openings of the tower, displaying iridescent colors and creating ever-changing and fast-moving fog shadows of the tower and the cables (Figure 2). I emailed a few images to Dr Andrew T. Young at the Astronomy Department, San Diego State Univ...

This pearl aims to demonstrate the ideas of wholemeal and projective programming using the Towers of Hanoi puzzle as a running example. The puzzle has its own beauty, which we hope to expose along the way.

in this paper the changes in the heat capacity of cooling towers has been investigated as a result of injecting combustion products of boilers. in the tower, the air is re-heated through mixing with hot flue gas after passing through the heat exchangers. as a result of this process, the draft of the cooling tower is increased. the additional produced draft depends on the ambient temperature and...

Screening of absorbents is essential for improving the removal rate carbon disulfide (CS2) waste air by absorption. In this work, UNIFAC model in Aspen Plus was utilized to calculate excess Gibbs function and absorption potential binary system CS2 with various alcohols, ethers, esters, amines, aromatic hydrocarbons. The results were used quantitatively compare efficiency each solvent theoretica...

Crude biodiesel needs to go through purification process, meet international specifications.. The widely used adsorption column is in the form of a fixed bed column, where contents are stacked mess. This makes adsorbent difficult clean and fill, irregular accumulation can hinder flow fluid be purified. In this study, an with portable circulation system observe influence level on purity biodiese...

Our theme bases on the classical Hanoi Towers Problem. In this paper we will define a new problem, permitting some positions, that were not legal in the classical problem. Our goal is to find an optimal (shortest possible) sequence of discs' moves. Besides that, we will research all versions of 3-pegs classical problem with some special constraints, when some types of moves are disallowed.
