comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Low-density parity-check (LDPC) codes can be applied to many different types of communication systems such as video broadcasting and satellite communications. However, the performance of the codes in practice may deviate a lot from the theoretical limits, achievable only by codes with infinite length. In this thesis, we will conduct a detailed investigation on the performance of short-length LD...
