The cable tower of Liede Bridge is a double-column curved-lever arched-beam portal framed structure. Being novel and unique in structure, its cable tower differs in complexity from traditional ones. This paper analyzes the ultimate load capacity of cable tower by adopting the finite element calculations and model tests which indicate that constitutive relations applied here give a better simula...

Using absorption refrigeration cycles instead of vapor compression refrigeration cycles can drastically decrease energy consumption. In these systems, high level of energy consumption is reduced due to the partially elimination of vapor compression refrigeration systems. On the other hand, utilization of waste heat of the plant, which is a very good opportunity for energy saving,  is possible. ...

The prefrontal cortex (PFC) plays an important role in cognitive function, involved in Executive Functions (EFs) such as planning, working memory, and inhibition. Activation in the PFC also occurs during some motor activities. One commonly used tool to assess EF is the Tower of Hanoi, demonstrating sensitivity to PFC dysfunction. However, limited neuroimaging evidence is available to support th...

this paper is an attempt to numerical modeling and experimental study of air flow in the yazdi wind-towers. wind towers has been known as one of the most effective climatic elements in iranian traditional architecture. this paper is an attempt to evaluating yazdi wind-tower to discussion the two main questions: 1. what is the role of orientation of wind-towers span, regarding to climate and hei...

Abstract In wet flue gas desulfurization technology, the key factor affecting SO 2 absorption is control of slurry pH value in tower. However, most commonly used methods have some defects and cannot fully meet system requirements. On basis analysis for problems process, this paper discussed a strategy based on internal model algorithm. The simulation test showed that method had good dynamic per...

this article is a comparative evaluation of airflow in two kinds of yazdi and kermani wind-towers. in the late decades of twenty century regarding to high population growth rate and energy crisis, vernacular architecture and its passive methods for gaining thermal comfort, has been strongly focused. moreover, a huge scientific movement setup for researches deep in exploring passive cooling and ...

7 A flue gas washer is a plant for the absorption of noxious components of industrial gas output. The type of flue gas washers that is considered here is a spray tower. In the tower gas is raising upward and water drops with suspended limestone fall downward. Thereby sulfur dioxide is washed out of the gas. In industrial practice, the plant is operated under long term constant gas and water inp...

The utilization of remotely sensed observations for light use efficiency (LUE) and tower-based gross primary production (GPP) estimates was studied in a USDA cornfield. Nadir hyperspectral reflectance measurements were acquired at canopy level during a collaborative field campaign conducted in four growing seasons. The Photochemical Reflectance Index (PRI) and solar induced chlorophyll fluoresc...

The in situ boundary layer measurement site in Białystok (Poland) has been upgraded with a fully automated observatory for total greenhouse gas column measurements. The automated Fourier Transform Spectrometer (FTS) complements the on-site in situ facilities and FTS solar absorption measurements have been recorded nearly continuously in clear and partially cloudy conditions since March 2009. He...
