This paper proposes a new method for rejecting the Continuous Wave Interferences (CWI) in the Global Positioning System (GPS) receivers. The proposed filter is made by cascading an adaptive Finite Impulse Response (FIR) filter and a Wavelet Packet Transform (WPT) based filter. Although adaptive FIR filters are easy to implement and have a linear phase, they create self-noise in the rejection of...

In this paper using nested Rectangular resonator we have designed an add-drop filter based on photonic crystal structures suitable for optical communication applications. The drop efficiency and the quality factor of our proposed filter is 100% and 2508. In this filter the quality factor is significantly improved with respect to other published reports. The simulation results are obtained using...

In order to comply with current trends concerning sustainability, saving of primary materials and energy savings, this paper addresses Eco-concrete. The major focus thereby is on the increased efficiency of cement use. Applying a new mix design method for concrete, cement contents can be decreased and partially be substituted by other fine powders, preferentially by waste powders which have no ...

in the several past years, extended kalman filter (ekf) and unscented kalman filter (ukf) havebecame basic algorithm for state-variables and parameters estimation of discrete nonlinear systems.the ukf has consistently outperformed for estimation. sometimes least estimation error doesn't yieldwith ukf for the most nonlinear systems. in this paper, we use a new approach for a two variablesta...

landfill gas is generated by organic waste decomposing under anaerobic conditions. landfill gas contributes to the emission in the atmosphere of greenhouse gases and causing global warming. humidity of environment is an effective parameter on rate of gas generation in landfills. saravan landfill is investigated as study area in this research. it located in 20 kilometers of rasht-tehran highway....

as regards the kind of use and production of biomass, lettuce plant has a potential to be used as a bioreactor for producing recombinant proteins as well as edible vaccines. for this propose optimized tissue culture as well as gene transformation of lactuca sativa are needed. seeds of 5 cultivars namely tn-96-35, tn-96-36, tn-96-39, tn-96-41, tn-96-53, and tn-96- 54 were disinfected by being so...

In this paper, a set of operators suitable for digit-serial FIR filtering is presented. The canonical and inverted forms are studied. In each of these structures both the symmetrical and anti-symmetrical particular cases are also covered. All circuits have been implemented using an EPF10K50 Altera FPGA. Main results show that the canonical form presents the less occupation and the higher throug...
