This seminar presents the manufacturing processes of thermoplastic structures including piezoceramic patches (PZT). The objective of the study reported here was to find a trade-off between the manufacturing conditions and the thermal endurance of the PZT patches. We studied the influence of high temperatures on the PZT efficiency during manufacturing. Two processes were considered: injection molding and thermoforming. The studied object consists of a polypropylene plate containing a PZT patch integrated at different positions. On the one hand, ....etc

Bridges are lifeline structures. They act, as an important page link in surface transportation network and failure of bridges during a seismic event will seriously hamper the relief and rehabilitation work. There are many cases of damage of bridges in the past earthquakes all over the world. Due to their structural simplicity, bridges are particularly vulnerable to damage and even collapse when subjected to earthquakes. The fundamental period of vibration of a majority of bridges is in the range of 0.2 to 1.2 second. In this range, the structur ....etc

ABSTRACT
Miniaturization is the order of the day. Until recently a decade ago traditionally watch parts were considered to be the micro components one can think off. Recent changes in societyâ„¢s demand have forced us to manufacture variety of micro components used in different fields starting from entertainment electronics to be bio medical implants. Present day manufacturing processes used for miniaturization are the micro electronic fabrication techniques used for Micro Electro Mechanical Systems ....etc

Most of the examples of collective behavior mentioned above are instances of crowd behavior. The classic treatment of crowds is Gustave LeBon, The Crowd: A Study of the Popular Mind (1896), in which LeBon shows himself to be a frightened aristocrat.

He interprets the crowd episodes of the French Revolution as irrational reversions to animal emotion, and]] such reversions as characteristic of crowds in general. Freud expresses a similar view in his Group Psychology and the Analysis of the Ego (1922).

This topic is devoted to the analysis of the mechanical behavior of filament-wound pipes. The process of filament winding makes it possible to produce rotating parts made of composite material containing polymers reinforced with long fibers. Most of the time, this process consists in winding a fiber tow coated with a thermosetting polymeric matrix around a mandrel, and thus covering the entire mandrel after successive passages. Following a polymerization phase, the mandrel can be removed in order to get only the composite structure. In certain ....etc

It is often desirable for structural steel members to pass through a fire wall
or common wall rather than being curtailed on each side of the wall. In such cases, the penetrating member will often be fire protected for a certain length on each side of the wall so as to minimise the possibility of fire spread through heat conduction and excessive temperature rise of the member on the unexposed side of the wall. This latter aspect is necessary to ensure that lateral restraint will continue to be provided to the top of the wall by the member on t ....etc
