In this paper, we study residuated lattices in order to give new characterizations for dense, regular and Boolean elements in residuated lattices and investigate special residuated lattices in order to obtain new characterizations for the directly indecomposable subvariety of Stonean residuated lattices. Free algebra in varieties of Stonean residuated lattices is constructed. We introduce in re...
In order to investigate the effect of Filter Cake application on some morpho-physiological characteristics and yield of sweet corn (Zea mays var saccharata) under different irrigation regimes, an experiment was conducted in Ramin Agriculture and Natural Resources University, Khuzestan, in 2012. The experiment was arranged in split-plot design in RCBD (Completely Randomized Block Design) with th...
This paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. The power filter integrates a passive power filter which is a RL low-pass filter placed in series with the load, and an active power filter which comprises an RL in series with an IGBT based voltage source converter. The filter is assumed...
a pilot anaerobic filter was used to remove cod from babolsar fiberboard production wastewater. the anaerobic filter was packed with ceramic packings and operated at different organic loading rates of 2.4 and 8 kg cod/m3 /day, in 20, 10 and 5 days hydraulic retention time (hrti), respectively. the reactor achieved cod removal of 80.3%, 81% and 79% for hrt 20, 10 and 5 days, respectively. in add...
Tracking filters are extensively used within object tracking systems in order to provide consecutive smooth estimations of position and velocity of the object with minimum error. Namely, Kalman filter and its numerous variants are widely known as simple yet effective linear tracking filters in many diverse applications. In this paper, an effective method is proposed for designing and implementa...

This paper reports a four-pole microstrip high-temperature superconducting (HTS) band-pass filter with a quasi-elliptic function response. A microstrip filter configuration that allows a pair of transmission zeros to be placed at the band edges is described. The filter was fabricated using single-sided YB2Cu3O7 superconducting thin film deposited on a LaAl2O3 single crystal substrate of size &n...
