Intelligent infrastructures systems for sustainable urban environment

Extensive research is now under way around the world to develop advanced technologies to enhance the performances of infrastructure systems. While these technological advances are incremental in nature, they will eventually lead to structures which are distinctly different from the actual infrastructure systems. These new structures will be therefore capable of Structural Health Monitoring (SHM), involving applications of electronics and smart materials, aiming to assist engineers in realizing the full benefits of structural health monitoring.intelligent infrastructures, environment, optimization

Using the WinQSB Software in Critical Path Analysis

In the present paper will be appealed sub modules from the PERT/CPM module of WinQSB software, adequate to solve the scheduling problems.CPM, PERT, critical path, normal duration, crash duration

Vibration isolated workplace

The paper presents the concern of the authors to realize a vibration-isolated workstation for own use. In this mean the authors have both modelled and experimented small scale devices, usable in vibration damping and control. The theoretical models use the spring(s)-damper(s)-mass model. The results of simulations were compared whit experiments made using Ni-Ti alloys with different shapes. The used theoretical model present sufficient accuracy for practical issues. The authors concluded that: regarding the device’s shapes the best results were obtained for semi-cylindrical elements; the mass of the stiff plate and equipment placed on it has also an important role in the damping system
