The authors would like to bring to the kind attention of the readers the following corrections to the paper 1 . Equation 23 in page number 917 is as follows f b00. 1 It should be noted that in 23 and all equations in the rest of the paper that contain the term b00 this term is the constant term of the polynomial B z1 z2 which is the stable version of the 2D PLSI polynomial B z1 z2 . Since we have assumed that bij s are the coefficients of the 2D PLSI polynomial the coefficients of the polynomial B z1 z2 are b ij s. Equation 46 in page number 920 is as follows A z1 zf 0.6 0.9z2 0.3z2 0.9z1 1.5z1z2 0.9z1z2 0.3z2 0.9z2z2 0.6z2z2 0.6z2z2 0.5z1z-1 0.8z2z-1 0.7z1z-2 z2z-2. 2 This equation may be corrected as follows A z1 zf 0.6 0.9z2 0.3z2 0.9z1 1.5z1z2 0.9z1z2 0.3z2 0.9z2z2 0.6z2 z2 0.5z1z-1 0.8z2z-1 0.7z1z-2 z2z-2. 3 Engineering Kigali Institute of Science and Technology KIST Rwanda for bringing to our attention one of the above corrections.
