    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Naveed Ahmed; Waqas Ahmed; [2010]
    Keywords : Hamming metric; Lee metric; Perfect codes; Minimal distance;

    Abstract : Perfect codes and minimal distance of a code have great importance in the study of theoryof codes. The perfect codes are classified generally and in particular for the Lee metric.However, there are very few perfect codes in the Lee metric. The Lee metric hasnice properties because of its definition over the ring of integers residue modulo q. READ MORE

    Keywords : Helmholtz equation; Local orthogonal transform; operator equation iii;

    Abstract : A method is developed for solving the two dimensional Helmholtz equation in a ductwith varying cross-section region bounded by a curved top and flat bottom, having oneregion inside. To compute the propagation of sound waves in a curved duct with a curvedinternal interface is difficult problem. READ MORE
