In a joint project with life sciences, we investigate the communications and code properties of the DNA. Our share deals with reasoning of the codon/aminoacid encoding structure, the error-protection, and source coding properties, whereas Prof. Mushelishvili’s group concentrates more on the influences of the three dimensional orientation leading to analog control mechanisms in gene

Student: Usama Nadeem Advisor: Prof. Dr.-Ing. Werner Henkel Dawit Nigatu Time frame: Spring 2016   Description: Bidirectional reading processes have been recently incorporated into the Lempel-Ziv family of lossless compression algorithms namely LZ-77, LZ-78 and LZW 84.  Bidirectional compression results in better compression ratios especially if the uncompressed data contains symmetric properties. In this work

  Student:  Nazia Sarwat Islam Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2013         Description: LZ77, LZ78, and LZW84 are universal lossless data compression algorithms for reducing redundancy. A modified version of these algorithms that takes into account both forward and reverse readings is presented in this work. It is shown

Student:  Dawit Andualem Nigatu Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Fall 2013         Description: In the previous project, we used classical multidimensional scaling (CMD) to scale down  the 64 x 64 ECM mutation matrix and 20 x 20 amino acid chemical distance matrix to 2  dimensions (2-D). From the 2-D representations,

Student:  Dawit Andualem Nigatu Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2013         Description: This research contains two separate parts. In the first part, we have used classical multidimensional scaling (CMD) technique to scale down a 64-dimensional empirical codon mutation (ECM) matrix and a 20-dimensional chemical distance matrix to two dimensions
