The development of the wastewater collection and treatment in Romania, as a result of the Adhesion Treaty, will lead to the production of higher and higher sludge quantities. Thus, an approximate increase of five times of the sludge quantity will result after treatment, by the year 2025, when all the localities over 2000 inhabitants should have sewerage networks and should be connected to a wastewater treatment plant which includes a sludge processing line. The treatment of the sludge is a necessity before being removed for storage or subsequent recovery. Purpose of treatment is to reduce or to eliminate potential decay and bad odours, as well to reduce the water content. The operators of the waste water treatment plants must identify the best environmental solutions and practices for the treatment, recovery/disposal of sludge, both sustainable and efficient in terms of costs.

The analysis refers to the possibility of creating a robotic parking lot placed in the centre of Bucharest, seismically isolated with the help of damping technologies. The effectiveness of non-conventional seismic damping technologies will be studied as an alternative to classical technologies. The elimination of the damages caused by earthquakes or other disruptive forces can be achieved through innovative solutions to reduce the amplitude of the seismic response of circular parking lots, without the occurrence of controlled structural degradation, as stipulated by the seismic design code P100-1/2018.

In order to solve the issue of parking places in Bucharest, a circular automated parking lot will be designed above the river Dâmbovi'a.

This paper studies the anti-vibration isolation of the elevator from a multi-storey car park. Too strong an excitation force cannot be applied to a resonant system, because it will develop vibrations of very large amplitudes. The damping is the one that controls the motion of a resonant system at its natural frequency. In order to reduce the response to the seismic acceleration, dampers will be used. The system's own pulsations will be calculated according to several models pulsation vibrator determined in the laboratory). [ABSTRACT FROM AUTHOR]

The ideal solution to protect the buildings from earthquakes is to control and limit the transfer of the seismic energy to a construction by the maximum dissipation of the seismic energy transferred to the building, which is achieved by the use of mechanical devices with which the seismic behavior of buildings is controlled. The protection of the structures exposed to the risk of earthquake is based on the three fundamental operational modes: insulation, connection, dissipation of energy. The centrically braced metallic frames provide resilience, rigidity and ductility, being thus ideal for the bracing of the seismic systems. Seismic insulation systems are designed to reduce the impact of earthquakes on buildings by means of special devices.

In the event of an earthquake, the energy radiates outward as seismic waves. The inner waves (longitudinal and transversal) move from the hypocenter to the outside, and the superficial waves move to the surface of the earth, those resulting from the inner waves that reach the surface of the soil.The P and S type of internal longitudinal and transversal seismic waves represent disruptive forces for any system. We propose to evaluate the own pulsation in case of the free vibrations of an overground parking. it is necessary that the wave pulsation to be different from the own pulsation of the system to be researched in order to avoid the phenomenon of resonance that is leading to the destruction of the system. We will consider the System Model with a degree of freedom for which we will determine its own pulsation and frequency. [ABSTRACT FROM AUTHOR]

It is considered an elevator that moves a vehicle within a multi-level parking lot. The electric drive engine of the elevator is a disturbing factor characterized by the pulsation ta, a vibration generator. The obtaining of a low own pulsation is achieved by the use of elastic insulators. In order to avoid the phenomenon of resonance, it is necessary the anti-vibration isolation of the system, which can be done by means of springs mounted on the foundation or by means of a rubber elastic rug mounted on the foundation. Advantages of the spring foundation: the creation of foundations with own frequencies, however low; taking over a variety of disruptive loads. Advantages of the rubber foundation: Taking over strong shocks, realization of low own pulsations; noise reduction silencer. Elements required for system anti-vibration isolation.

The overground parking lot including a robot-driven elevator has the advantage of complete automation.
