EVALUATION OF METEOROLOGICAL DROUGHT EFFECTS IN THE REDUCTION OF GROUND WATERTABLE (CASE STUDY: TABRIZ PLAIN)

Evaluation of Meteorological Drought Effects in the Reduction of Ground Watertable (Case study: Tabriz Plain)

Tabriz plain has located in east of Urmia lack.In certent decades alternate and continued droughts have occured in the region and Tabriz plain.Contemporary ground watertable has decreased greatly.Therefore it seems there is a significant interaction between meteorological drought and fall of ground watertable.The goal of this study is to do researc

A Novel Reciprocating Tribometer for Friction and Wear Measurements with High Contact Pressure and Large Area Contact Configurations

There are many moving machine assemblies with conformal tribological contacts at very high contact pressures, e.g., sliding bearings, propeller shaft bearings and machine guideways.Furthermore, applications such as trunnion and guide vane bearing in Kaplan turbines have very low sliding speeds and oscillatory types of motion.Although there is a vas

Topology-Aware Space-Time Network Coding in Cellular Networks

Space-time network coding (STNC) is a time-division multiple access (TDMA)-based scheme that combines network coding and space-time coding by allowing relay nodes to combine the information received from different source nodes during the transmission phase and to forward the combined signal to a destination node in the relaying phase.However, STNC
