The aim of the current study is to develop a numerical tool that is capable of achieving an optimum shape and design of hyperbolic cooling towers based on coupling a non-linear finite element model developed in-house and a genetic algorithm optimization technique. The objective function is set to be the minimum weight of the tower. The geometric modeling of the tower is represented by means of ...

In this paper, Hop eld neural networks have been considered in solving tower of Hanoi test which is used in determining of de cit of planning capability of human prefrontal cortex. The main di erence of this work from the ones in the literature which use neural networks, is: The tower of Hanoi problem has been formulated here as a special shortest path problem. In the literature, some Hop eld n...

A way to see this work is how it connects existing elements. The goal is not so much to invent all new things, but to compose a new meaningful whole of different elements so that they will complement each other in novel ways. There are already massively multi-player on-line roleplaying games (mmorpg), where people participate in different worlds. Also, there are public displays with which peopl...

CPU speeds are increasing at a much faster rate than secondary storage device speeds. Many important applications face an I/O bottleneck. We demonstrate that this bottleneck can be alleviated through 1) scalable striping of data and 2) caching/prefetching techniques. This paper describes the design and performance of the Tower of Pizzas (TOPs), a portable software system providing parallel I/O ...

Macros are re ective tools that operate on the representation of programs. Though having been used, and still being useful, for more than thirty years, their semantics and pragmatics are still unclear. This paper proposes a new model to understand the macroexpansion process; this model is based on a re ective tower of macroexpansion engines.

Wind turbine towers are large structures designed to withstand the unique loading conditions imposed on them by the turbine’s nacelle and dynamic forces from the rotating blades. Observations and noise measurements of a particular wind turbine showed high noise levels at approximately 48 Hz, which could not be explained from the usual known potential noise sources. Correlated far field noise me...

BACKGROUND An outbreak of Legionnaires' Disease took place in the Swedish town Lidköping on Lake Vänern in August 2004 and the number of pneumonia cases at the local hospital increased markedly. As soon as the first patients were diagnosed, health care providers were informed and an outbreak investigation was launched. METHODS Classical epidemiological investigation, diagnostic tests, environ...

Sherman, Erica, "Fluid dynamic factors as a cause and effect of biofilm formation of Staphylococcus aureus biofilms" (2016). Staphylococcus aureus bacteria are able to form biofilms and distinctive tower structures that facilitate their ability to tolerate treatment and to spread within the human body. The formation of towers, which break off, get carried downstream and serve to initiate biofil...

We examine the relationship between cell phone use and traffi c accidents using a unique measure of cell phone coverage. The distance from an antenna tower accurately predicts whether or not an area has cellular coverage according to provider coverage maps in 2016. Cellular coverage between 2001 and 2011 is proxied for using the the distance between a road segment and the nearest antenna tower....

Introduction Fatigue is the structural damage that leads the components of a wind turbine to sudden brittle failure when it suffers cyclic loading [15]. As the size of wind turbines is growing, fatigue loads become more and more significant for the design of major structural components. Concerning fatigue in a wind turbine tower, the fore-aft tower foot bending moment is considered as the most ...
