of formation ∆ f Ho of a large number of atoms, free radicals, ions, clusters and compounds is available from the websites of NIST, NASA, CODATA, and IUPAC . Most authors prefer to use the BDE values at 298 .15 K . The following seven tables provide essential information of ex-perimental BDE values of R−X and R+−X bonds .
ing on standardizing SystemVerilog in 2001, additional issues were identified that could possibly have led to incompatibilities between Verilog 1364 and SystemVerilog. The IEEE P1364 Working Group was estab-lished as a subcomittee of the SystemVerilog P1800 Working Group to help ensure consistent resolution of such issues.

LDPC Codes – a brief Tutorial Bernhard M.J. Leiner, Stud.ID.: 53418L bleiner@gmail.com April 8, 2005 1 Introduction Low-density parity-check (LDPC) codes are a class of linear block LDPC codes. The name comes from the characteristic of their parity-check matrix which contains only a few 1’s in comparison to the amount of 0’s.
