Non Binary Low Density Parity Check (NB-LDPC) codes, a category of LDPC codes have better decoding performance in high order Galois field. A construction method called hierarchically diagonal matrix (HDM) is proposed in this paper. The constructed HDM is analyzed for IEEE 802.11 n specification of code length 648, rate 1/2 over GF (4). Codes constructed based on the hierarchical matrix perform well...
Increased environmental awareness and quick depletion of natural resources are driving the researchers to develop viable alternative fuels from renewable resources that are environmentally more acceptable. The use of oxygenates to replace the lead additives in gasoline are being considered as an alternative. In this work, oxygenated fuel is prepared by mixing 80% of gasoline with 10%, 5% and 5% (composition...
The present investigation shows that the agricultural by-products like bengal gram husk, tur dal husk, and tamarind husk can be used as an effective adsorbent for the treatment of wastewaters containing metals like chromium (VI), iron (III), nickel (II) and mercury (II). The term biosorption commonly refers to the passive binding of metal ions or radioactive elements by dead biomass. It has to be...
The effect of Phanerochaete Chrysoporium whole cells and their ligninolytic enzymes on models of colored industrial waste waters was evaluated. Model of reactive dyes waste waters from textile industry have been defined on the basis of discharged amounts, economic relevance and representativeness of chemical structures of the contained dyes. Phanerochaete Chrysoporium provided on effective decolourisation...
