Abstract    Historical monument of Menar-Jonban (shaking tower) is located in the famous city of Isfahan in central Iran. Initial construction of this interesting and unique masonry monument belongs to 700 years ago. This monument has two vibrating circular towers of 7.5 m height. These towers are separated from each other by a distance of 9.2 m and constructed on top of an ancient tomb of 10 m...

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 he...

In the millennial era, development of information and communication technology is very fast, one telecommunications infrastructure a monopole type tower. This tower 3 types telecommunication towers whose main construction made steel. The structure supported by tread foundation, which shallow foundation. factor in design foundation bearing capacity factor. Calculation can be done directly field ...

The most relevant differences existing between wheeled and legged robots, from the point of view of the expected navigation tasks to be performed using each kind of locomotion, are reviewed. We propose a new framework for legged robot navigation that replaces many implicit assumptions usually made for wheeled robots by new ones that are better suited to legged robots. Based on this, specific te...

We present a general trajectory generation scheme for a class of “kinematic” legged robots. The method does not depend upon the number of legs, nor is it based on foot placement concepts. Instead, our method is based on an extension of a nonlinear trajectory generation algorithm for smooth systems to the legged case, where the relevant mechanics are not smooth. Our extension is based on the rea...

Editorial Corridors and Towers When C P Snow wrote "The Corridors of Power" he sought to demonstrate the inner workings of the political process in Whitehall. Now that we are coming towards the end of the useful life of the building known as the "RVH corridor" it is time to consider some of the inner workings of our own profession. Wards 1-20 in the Royal Victoria Hospital represent only a smal...

We formulate variants of the cardinals f, p and t in terms of families of measurable functions, in order to examine the effect upon these cardinals of adding one random real.

Given two isospectral not isometric manifolds, we construct a new couple of such manifolds as the total spaces of two Riemannian submersions with totally geodesic fibers isometric to the given ones and of basis any other given manifold. By iteration, we obtain families of isospectral not isometric manifolds.
