Abstract The new challenges related to the monitoring of Earth’s shape and motion have led global geodetic observing system set more stringent requirements on precision stability terrestrial reference frame (TRF). achievement this ambitious goal depends improvement space geodesy techniques, satellite laser ranging (SLR) in particular, being main instrument for TRF realization. In work, we study...

although studies on the relation between size and efficiency are ample, studies on the relation between size, fragmentation, and efficiency are limited. it is the purpose of this study in which a single-stage stochastic parametric approach is used. for this purpose production of wheat in iran is a good case because wheat is the core commodity of the iranian agricultural system which is dominate...

The translation of Digital products applicable to military application has been affected by the DoD's need for lower cost products. Products developed for military application must retain robust mechanical characteristics; however, each product may be tailored to meet government specifications such as mean time between failure and temperature range. Design changes for military use have had a be...

In a previous paper Low91] we presented two new models of timed CSP. The rst model included biased operators in the syntax, which could be used to model diierent priorities on actions. The second model extended this by adding a probabilistic choice operator to the syntax; this allowed us to give a semantics which modelled the probabilities of diierent behaviours occurring. In Low92b] we present...
