This paper deals with unequal error protection for code symbols of convo-lutional codes. The unequal error protection can be achieved due to different distanceproperties of output sequences and is sometimes described in terms of the correspondingeffective free distances. However, in many situations the effective free distance does notprovide enough information on the error-correcting capability. W
Most people agree that the total ecological impact of society has become more than this planet can endure. This is because we consume our resources (such as oil and water) faster than they can regenerate and because we release more substances into the environment than can be assimilated (e.g. CO2). In other words: our society is not sustainable on a long term basis. Biocatalysis is being promoted
This paper reviews work on self-tuning regulators. The regulator algorithms, their theory and industrial applications are reviewed. The paper is expository—the major ideas are covered but detailed analysis is given elsewhere.
