1. An Encounter with Convolutional Codes over Rings
Abstract : Convolutional codes is one possibility when there is a need for error-correcting codes in communication systems. Using convolutional codes over rings is a relatively new approach. READ MORE

2. Parity check systems, perfect codes and codes over Frobenius rings
Abstract : This thesis consists of five papers related to coding theory. The first four papers are mainly devoted to perfect 1-error correcting binary codes. The fifth paper concerns codes over finite Abelian groups and finite commutative Frobenius rings. In Paper A we construct a new class of perfect binary codes of length 15. READ MORE

3. Efficient Coding Techniques for Networks & Channels with Transmission Errors
Abstract : This thesis consists of two parts, both of whichinvestigate coding techniques for information transmission throughchannels in the presence of errors. Part I discusses topics ofnetwork coding and rateless codes. Part~II considers channel codesfor continuous phase modulation. These two parts are clearlydifferent, but they are also related. READ MORE

4. Manufacturihng of heavy rings and large copper canisters by plastic deformation
Abstract : Plastic deformation processes transform material fromas-received state to products meeting certain requirements inproperties, microstructure and shape. To achieve thistransformation, the relationship between material response andprocess conditions should be understood. READ MORE
