due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
The compact relationship between stratospheric temperatures (as well as ozone) and tropospheric generated planetary wave activity have been widely discussed. Higher wave activity leads to a strengthening of the Brewer-Dobson (BD) circulation, which results in warmer/colder temperatures in the polar/tropical stratosphere. The influence 5 of this wave activity on stratospheric water vapor (WV) is...
cognitive studies of translation process have recently been awarded a great deal of attention. there exists a psychological angle to almost all translation activities. the present study, thus, deals with analysing the relationships between iranian prospective translators tolerance for ambiguity (ta) and their willingness to translate (wtt). the research was conducted as a mixed methods study, d...
[1] The strong jet, with a speed between 500 and 600 m/s, is inferred in the equatorial region of Saturn by combining the nadir and limb observations of Composite Infrared Spectrometer (CIRS) aboard the Cassini spacecraft. A similar jet was discovered on Jupiter (F. M. Flasar et al., 2004a). These discoveries raise the possibility that intense jets are common in the equatorial stratospheres of ...
Abstract As a major source of moisture in Central Asia (CA), snowfall may significantly impact agriculture and economics CA. The study has investigated the dominant modes frequency during winter over CA associated mechanisms. first EOF mode (EOF1) corresponds to homogeneous pattern In contrast, second (EOF2) is characterized by reversed anomalies northern southern mechanisms interannual variati...
The impact of polar stratospheric ozone loss resulting from chlorine activation on polar stratospheric clouds is examined using a pair of model integrations run with the fully coupled chemistry climate model UM-UKCA. Suppressing chlorine activation through heterogeneous reactions is found to produce modelled ozone differences consistent with observed ozone differences between the present and pr...
