The construction industry is responsible for one of the highest incidences of work-related accidents in Brazil, as well as in various other countries. In spite of the dissemination of prevention programs and the proposals for developing safety design for the construction industry, construction sites remain dangerous and unhealthy places. Recently, safety has been proposed to be considered from ...

In the paper, a procedure for the automatic rectification of images is described. The procedure uses some targets fixed to the vertices of a 2 m x 2 m square frame. The frame is positioned on the surveyed surface (e.g. a building facade or a road where an accident occurred). The position of the target vertices is obtained through a correlation between the image we should rectify, and the image ...

Rammed earth is a sustainable material with low embodied energy. However, its development as a building material requires a better evaluation of its moisture-thermal buffering abilities and its mechanical behavior. Both of these properties are known to strongly depend on the amount of water contained in wall pores and its evolution. Thus the aim of this paper is to present a procedure to measur...

We develop a system for predicting the level of language learners, using only a small amount of targeted language data. In particular, we focus on learners of Hebrew and predict level based on restricted placement exam exercises. As with many language teaching situations, a major problem is data sparsity, which we account for in our feature selection, learning algorithm, and in the setup. Speci...

My talk is divided into five parts. In the first part the relevance of the chiral fermion issue to fundamental particle physics and to numerical QCD will be explained. In the second part the basic ideas of the overlap construction will be reviewed. In the third part I shall focus on the algebraic (as opposed to kinematic) meaning of the overlap. In the fourth part I shall discuss in greater det...

induction motor especially the squirrel cage type of this motor plays important role in industry. according to the application type, this motor place against various stresses that are caused failure in the motor. the most common failure is related to the stator winding. among these failures are turn-to-turn, coil-to-coil and phase to phase faults. flow the high current do to the induction resul...
