In this paper, the two-dimensional vibration controls of a power transmission tower with a pounding tuned mass damper (PTMD) under multi-component seismic excitations are analyzed. A three-dimensional finite element model of a practical power transmission tower is established in ABAQUS (Dassasult Simulia Company, Providence, RI, USA). The TMD (tuned mass damper) and PTMD are simulated by the fi...

The purpose of multi-tower crane motion planning is to find a collision-free construction process for multiple tower cranes operating in a construction site. This problem can be reduced to the path searching problem in highdimensional space and an important amount of research related to the path search algorithm has been published in various fields. In this paper, we analyzed the features of hi...

This result has an application to the hyperbolic subset of the p-adic Mandelbrot set, whose complex analogue has been much studied [2, 4, 5, e.g.]. Much of the proof of (2) is an analysis of the Galois tower formed by the splitting fields of iterates of y2+x ∈ Fp(x)[y]. Similar towers have been studied recently by Morton [7], Odoni [8], and Aitken, Hajir, and Maire [1]. I introduce a stochastic...

Requirement Engineering acts as foundation for any software and is one of the most important tasks. Entire software is supported by four pillars of requirement engineering processes. Functional and non-functional requirements work as bricks to support software edifice. Finally, design, implementation and testing add stories to construct entire software tower on top of this foundation. Thus, the...

in this paper, to address the effect of reactor performance and configuration of biodiesel production on subsequent process parameters (including mass & energy consumption, required facilities etc.) two diverse biodiesel production processes (from plant oil) were implemented/designed using aspen hysys v7.2. two series reactors were taken into account in these designs where in the first and seco...

cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. this paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. the tower is filled with 6 type packing. in this study temperature and pressure drop and tower characteristics was used in determining experimentally the ther...
