In a steam power plant, the temperature of the cooling water leaving the condenser for recyclingshould decrease. This is achieved in a cooling tower. The Heller cooling tower does not require waterfor operation, thus, it is a suitable system for use in thermal power plants throughout Iran. Wind is anenvironmental factor that unfavorably affects the performance of a cooling tower. Previous studi...

According to the design requirements of super long-span pedestrian landscape cable-stayed bridge in Lake view Park, a kind sightseeing tower-style three-tower structure system was proposed. Sightseeing tower type and duck egg arched replace traditional structure. Through establishment Midas finite element analysis model, dynamic modal research carried out. The shows that: are combined into one,...

Today, tower cranes are in widespread use on construction sites all around the world. An important issue that arises when operating these cranes is the oscillatory behavior that occurs during payload transportation, which can have severe effects on safety as well as accuracy of payload delivery. Due to the nonlinear nature of the rotating crane motion, controlling these oscillations is a comple...

Unattended measurements of carbon dioxide (CO2) mixing ratio at three altitudes up to 496 m above the surface on a television transmitter tower in the southeastern United States have been made for a period of 4 yr. This report describes the design of the automatic tower measuring system in detail. A nondispersive infrared (NDIR) analyzer is used to measure the CO2 concentration continuously. Re...

This paper presents a universal engineering model, which can be used to formulate both counterflow and crossflow cooling towers. By using fundamental laws of mass and energy balance, the effectiveness of heat exchange is approximated by a second order polynomial equation. Gauss-Newton and Levenberg-Marquardt methods are then used to determine the coefficients from manufactures data. Compared wi...

This paper explores the interaction between implicit and explicit processes during skill learning, in terms of top-down learning (that is, learning that goes from explicit to implicit knowledge) versus bottom-up learning (that is, learning that goes from implicit to explicit knowledge). Instead of studying each type of knowledge (implicit or explicit) in isolation, we stress the interaction bet...

A technical challenge in deploying a floating offshore wind turbine shallow water is dissolution of the poor performance catenary mooring system due to decreased absorbable potential energy. It common practice improve by using buoys and sinkers enhance energy absorbed system. In this research, tower-shaped buoy (tower-buoy) proposed which sinker integrated structure. design, relatively large ar...

Modelling and computational simulation are crucial for the large-scale engineering of biological circuits since they allow the system under design to be simulated prior to implementation in vivo. To support automated, model-driven design it is desirable that in silico models are modular, composable and use standard formats. The synthetic biology design process typically involves the composition...
