This research aims to provide a suitable method analyze high-frequency electromagnetic scattering from extra-high voltage (EHV) transmission line towers with different tower types using characteristic mode theory (CMT). Different the traditional idea of passive protection based on spatial avoidance, this combines existing and CMT modal decomposition decompose total responses into superposition ...

objective: the purpose of this study is to compare the executive functions children and adolescents who suffer from attention deficit hyperactivity disorder (adhd) with normal children. method: twenty children with adhd were compared to 19 healthy children terms of some executive functions using the computerized version of tower london, continuous performance test (cpt), and stroop color test. ...

We develop a general framework for various lattice-valued, probabilistic and approach uniform convergence spaces. To this end, we use the concept of $s$-stratified $LM$-filter, where $L$ and $M$ are suitable frames. A stratified $LMN$-uniform convergence tower is then a family of structures indexed by a quantale $N$. For different choices of $L,M$ and $N$ we obtain the lattice-valued, probabili...

Tower cranes are major and expensive equipment that are extensively used at building construction projects and harbors for lifting heavy objects to demand points. The tower crane locating problem to position a tower crane and supply points in a building construction site for supplying all requests in minimum time, has been raised from more than twenty years ago. This problem has already been so...

Climate change continues to affect the lives of individuals across world, creating a rise in demand for new technologies that can slow down impacts climate change. Shanghai, one largest cities has highest carbon emission levels. In recent years, research and development energy-efficient have gained more attention. The Shanghai Tower is pioneer green building design prominent example Shanghai’s ...

I describe an architecture for linking perception and action in a robot. It consists of three “towers” of layered components. The “perception tower” contains rules that create increasingly abstract descriptions of the current environmental situation starting with the primitive predicates produced by the robot’s sensory apparatus. These descriptions are deposited in a “model tower” which is cont...

In view of the insufficient analysis coupled joint seismic response intake tower–reservoir water–foundation boundary under oblique incidence SV wave space, a three-dimensional dynamic equation space is established in this paper. The external input method viscoelastic artificial combined with equivalent load and acoustic medium theory are used to simulate action reservoir water, angle change rea...

A downburst is one of the high-intensity winds that cause transmission tower failures. In recent years, downbursts have brought great disasters to economies and lives people all around world. this paper, dynamic stability tower-line system under a analyzed. The deterministic-random mixed model used generate wind field ANSYS software employed establish finite element system. response characteris...

In this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. The trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. The industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. The study was composed of two parts. In the first section...

Transmission tower is a very important component of power system, and heavy iced transmission line has became one of the important factors against its safety and stability in China's power system these years but the transmission line designed from traditional standard can't endure the more worse environment. In this paper, for positioning the weak points of the transmission line under heavy ici...
