Complete randomization in many industrial and agricultural experiments is frequently impractical due to constraints in time, cost or existence of one or more hard-to-change factors. In these situations, restrictions on randomization lead to split-plot designs (SPD), allowing certain factor levels to be randomly applied to the whole plot units and remaining factor levels randomly to the subplot ...

abstract to evaluate the effects of the irrigation termination in different growth stages on yield and its components of autumn’s canola cultivars in isfahan region. an experiment was conducted in 2005-2006 in kabotar abad research station. a split plot layout within a randomized complete block design with tree replication was used. main plots were seven level of the irrigation cut-off time (d1...

This paper presents the design and analysis two-stage operational transconductance amplifier (OTA) for use in switched-capacitor (SC) circuits. The existing design methods for two-stage OTAs often lead to sub optimal solutions because they decouple inter-related metrics like noise and settling performance. In our approach, the cadence tool is used to analysis the transient response, AC response...
