Vibration reduction in harmonically forced undamped systems is considered using a new vibration absorber setup. The vibration absorber is a platform that is connected to the ground by a spring and damper. The primary system ...

A Reconfigurable Computer (RC) is a hardware platform that typically includes several programmable devices, memory devices, and possibly specialized devices such as analog-to-digital converters. Such high-performance ...

The method of direct partition of motion (DPM) has been widely used to study the dynamics of non-autonomous oscillatory systems subject to external high frequency excitation. In this work, we explore the non-trivial dynamics ...

We investigate the dynamics of a spinning top whose pivot point undergoes a small amplitude high-frequency vertical vibration. The method of Direct Partition of Motion is used to obtain an autonomous equation governing the ...

Lebanon and southwestern Syria comprise a prominent, 200-km long restraining bend along the Dead Sea fault system (DSFS) - the continental transform boundary between the Arabian and Sinai plates. Within this "Lebanese ...

A targeted experimental program was carried out to establish basic reference physical and mechanical properties of commercially available pre-cast marble chip terrazzo tiles and to investigate the effects of varying ...

Criteria air pollutants: PM10, CO, SO2 and NO2, as well as general meteorological conditions were monitored for the first time ever at five locations in and around the cement industry zone situated in Northern Lebanon in ...

A general modification to the models used for the study of the effect of fiber volume on the strength properties of short fiber reinforced cements is presented. It considers the composite as a mix of cement paste, fibers, ...
