different conservation tillage practices are nowadays suggested as the best solution for prevention of soil from erosion. this could be done by leaving the previous crop residue on the soil surface. a new idea to plant in the conservation tillage system is the use of punch planters by which one can plant through a heavy depth of previous crop surface residue. the study was conducted using a 2?3...

data envelopment analysis (dea) measures the relative efficiency of decision making units (dmus) with multiple inputs and multiple outputs. dea-based malmquist productivity index measures the productivity change over time. we propose a dynamic dea model involving network structure in each period within the framework a dea. we have previously published the network dea (ndea) and the dynamic dea ...

Evaluation has been an essential component of the teaching and learning process for as long it a part itself, which is something that takes place all time at every educational institution. This because assessment tight link with educators in transferring information to analyze how much students' abilities have developed over course while assembling each assignment learning. study tries shed lig...

Recently, orthogonal time frequency space modulation with index (OTFS-IM) has been proposed to improve the bit-error-rate (BER) performance of OTFS system. However, only some grids in OTFS-IM system are activated, resulting low spectral efficiency (SE). In order solve this problem, a new scheme called multiple-mode (MM-OTFS-IM) is paper. scheme, all activated transmit bits. Each grid subblock a...
