In this article, a novel simplified dual-composite right/lefthanded transmission line (S-D-CRLH-TL) is proposed according to the theory of dual-composite right/left-handed transmission line. The electromagnetic characteristics of S-D-CRLH-TL are analyzed by simulator, and the results indicate that the proposed structure has two narrow stopbands; they can be controlled by changing the geometry p...

-Compost filter socks are generally used to control sediment on construction sites or land disturbing activities. Higher sediment removal efficiencies of compost filter socks, relative to silt fence, have been attributed to its larger surface area and sediment storage capacity, due to its tubular construction. Compost has been used widely to bioremediate polluted soils. By adding new materials ...

By first principle calculations, a dual spin filter effect under finite bias voltages is demonstrated in an antiferromagnetic junction of symmetric zigzag graphene nanoribbon (ZGNR). Unlike conventional spin filter devices using half metallic materials, the upand down-spin electrons are unidirectionally filtered in the counter direction of the bias voltage, making the junction a dual spin filte...

The following methods of CPFSK signals demodulation are compared for phase and polarization diversity receivers: single filter, dual filter, delay and multiply. BER values are obtained in each case showing that for negligible laser linewidths the delay demodulation method outperforms the dual-filter method by approximately 3 dB, and the single-filter method by 6 dB. Since the noise bandwidth fo...

An identity of F.H. Jackson is used to derive general bilateral summation formulae for q-series which unifies several generalizations of Gasper’s bibasic summation formula with different independent bases, and we also obtain the dual formula for the different generalization related to Gasper’s formula.

Bioretention cells (BRCs) have shown potential for storm water quantity and quality control. However, the phosphorus (P) removal in BRC has been variable due to differences of soil properties in filter media. The objectives of this research were to identify and evaluate P accumulation in filter media and to quantify effluent P reduction in BRC. Each cell has a sand and fly ash media designed to...
