In South Africa canola (Brassica napus L.) is cultivated in rotation with wheat under winter rainfall the Western Cape Province, primarily for seed to make oil. Expansion of crop other 8 provinces proposed reduce shortages locally produced plant oils. At same time, can serve as a rotational these summer provinces. central Free State, information on evapotranspiration and various water use indic...

A proper understanding of factors affecting evaporation and drift losses in sprinkle irrigation is important for developing water conservation strategies. For estimating drift and evaporation losses during the set sprinkler irrigation event, several outdoor single-sprinkler and block irrigation tests have been conducted. Various sprinkler±nozzle±riser height combinations were used and the varia...

The water use efficiency under conventional flood method of irrigation, which is predominantly practised in Indian agriculture, is very low due to substantial conveyance and distribution losses. Recognizing the fast decline of irrigation water potential and increasing demand for water from different sectors, a number of demand management strategies and programmes have been introduced to save wa...

Introduction In modeling real world tasks, one inevitably has to deal with uncertainty. This uncertainty is due to the fact that many facts are unknown and or simply ignored and summarized. Suppose that one morning you find out that your grass is wet. Is it due to rain, or is it due to the sprinkler? If there is no other information, you can only talk in terms of probabilities. In a probabilist...

Static Synchronous Compensator (STATCOM) is a FACTS device whose structure is based on a voltage source converter and is installed in parallel to control the voltage of the transmission line in the power system. In this paper, a flat adaptive control system for STATCOM output voltage control is simulated. By linearizing the nonlinear dynamics and changing the system state variables, the control...
