Noise Attenuation Due to Vegetation
It is well-known that noise decreasing techniques are based on two types of methods: one active and another passive. The latter often employs the vegetation which is planted forming green protection zones areas. In this...
Passive and semi-active bracing systems for seismic protection: a comparative study
This paper analyses comparatively the seismic response of structures equipped by two types of dissipative bracing systems: passive devices with variable friction and semi-active devices with magnetoreological fluids. Bot...
Seismic Isolators - Double Sliding Bearings
The seismic protection of buildings by seismic isolation is continuously improving since many years. Many new materials and different shapes are contributing to the development of recent high performance devices. As seis...
Exact Controllability in Oblique Gridworks Structures
The article studies the problem of the exact internal controllability on a gridwork structure that depends on two small parameters ε and δ . The controll is provided by the HUM method (Hilbert Uniqueness Method). We appl...
MODERN METHODS FOR NOISE CONTROL
Noise can be defined as unwanted sound. There are many cases and applications that reducing noise level is of great importance. Loss of hearing is only one of the effects of continuous exposure to excessive noise levels....
