Velocity model technique is routinely used to convert data from the time-to-depth domain to support prospect evaluation, reservoir modelling, well engineering, and further drilling operation. In Vietnam, the conventional velocity model building workflow oversimplifies the interval velocities as only well interval velocities are populated into 2D grids for depth conversion or oversimplified calibration interval velocities by applying a single scaling factor function.

The finite element method (FEM) has been successful in simulating complex physical systems in science and engineering. A big challenge of using the FEM is how to reduce computation time in large-scale problems. In this paper, we propose combining the FEM and an Adaptive Mesh Refinement (AMR) technique for solving an incompressible fluid flow on unstructured grids.

A 560m2 naturally ventilated greenhouse (Fig. 1) was constructed at the research farm of Department of Soil and Water Engineering, Punjab Agricultural University, Ludhiana. A similar greenhouse was also constructed at Krishi Vigyan Kendra, Faridkot. Capsicum was cropped during the studying period at both experimental areas in different period of time. Temperature inside the greenhouse at various places was recorded on hourly basis from 0700 hours to 1800.

The agriculture sector nowadays in Palestine relies mostly on conventional energy sources and traditional irrigation ways. Considering some factors such as high costs of fossil fuels and providing new electrical network, especially to remote areas and where grid electricity is either inaccessible or expensive to expand, therefore a solar photovoltaic (PV) powered irrigation system can be a practical choice for irrigating.
