Xi'an Bell Tower (the Bell Tower) is a state-level ancient relic in China. The vibration caused by metro will exert adverse effect on the Bell Tower. This paper aims at presenting 3D-FEM models to predict the peak period velocity (PPV) of rammed earth base when the metro passing through the Bell Tower. The calculation results are compared with those of field test. Both results were found to be ...

The purpose of this paper is to prove the Frame-Stewart algorithm for the generalized Towers of Hanoi problem as well as finding the number of moves required to solve the problem and studying the multitude of optimal solutions. The main idea is to study how to most effectively move away all but the last disc and use the fact that the total number of moves required to solve the problem is twice ...

Combinatorial properties of the multi-peg Tower of Hanoi problem on n discs and p pegs are studied. Top-maps are introduced as maps which reflect topmost discs of regular states. We study these maps from several points of view. We also count the number of edges in graphs of the multi-peg Tower of Hanoi problem and in this way obtain some combinatorial identities.

Recently, there has been increased interest in moving the RF electronics in basestations from the bottom of the tower to the top, yielding improved power efficiencies and reductions in infrastructural costs. Tower-top systems have faced resistance in the past due to such issues as increased weight, size, and poor potential reliability. However, modern advances in reducing the size and complexit...

he present paper deals with the study of static and dynamic analysis of transmission line tower (X type of bracing system). A typical type of transmission line tower carrying 220KV single circuit conductor is chosen as case study existing in bijapur district. The analysis and modeling of tower is carried out using FE based ANSYS software. The model is created in CATIA and then imported to ANSYS...

In order to locate a 150m wind monitoring tower to measure the wind characteristics, we investigated the site near Paradip, Odisha (India) to locate wind tower and collected some wind data to incorporate into the design of tubular steel tower. This paper seeks to understand the design of tubular steel tower and its performance parameter up to 150m height, also it provides the stability analysis...

Procedurally reeective programming languages enable user programs to semantically extend the language itself, by permitting them to run at the level of the language implementation with access to their context. The reeective tower, rst introduced by Brian Smith 9, 10], is the principal architecture for such languages. It is informally described as an innnitely ascending tower of meta-circular in...

Procedurally re ective programming languages enable user programs to semantically extend the language itself, by permitting them to run at the level of the language implementation with access to their context. The re ective tower, rst introduced by Brian Smith [9, 10], is the principal architecture for such languages. It is informally described as an in nitely ascending tower of meta-circular i...

In this paper, tuned mass dampers with optimal parameters for long span transmission tower-line system are investigated. Equations of motion for a structure-TMD system are derived, and the parameters of TMD, stiffness and damping are optimized, respectively. According to a real project, three-dimensional finite element models of both transmission tower and transmission tower-line system are cre...

The article presents the transients analysis of the substation grounding systems and transmission line tower footing resistances which can affect to the back-flashover (BF) or overvoltage across insulator chain in an HV power systems by using EMTP-RV software. The related transient modeling of the grounding systems is based on a transmission line (TL) model with considering the soil ionization....
