- Description: This paper presents parts-of-speech tagging as a first step towards an autonomous text-to-scene conversion system. It categorizes some freely available taggers, according to the techniques used by each in order to automatically identify word-classes. In addition, the performance of each identified tagger is verified experimentally. The SUSANNE corpus is used for testing and reveals the complexity of working with different tagsets, resulting in substantially lower accuracies in our tests than in those reported by the developers of each tagger. The taggers are then grouped to form a voting system to attempt to raise accuracies, but in no cases do the combined results improve upon the individual accuracies. Additionally a new metric, agreement, is tentatively proposed as an indication of confidence in the output of a group of taggers where such output cannot be validated.

Applications of thermal spray technology for surface protection

- Description: With the rapid development of modern industry, the quality of surfaces of structures, products and components is important in terms of many aspects such as efficiency, reliability, appearance, maintenance costs and economy. A local failure on the surface usually causes the entire component to be rejected or it may lead to a failure of a machine or structure. It is estimated that in developed countries, the loss caused by corrosion is up to 2-4% of gross national product [1]. Thus, many countries have made great efforts to improve the surface performance of parts in order to enhance the reliability of mechanical equipment and prolong their service life.

- Description: The Faculty of Arts has been requested to drive one of the NMMU research themes, namely "Social cohesion". Being a memeber of the Faculty of Arts and from the School of Governance and Social Sciences I have decided to provide some input regarding this theme. South Africa experienced violent xenophobic attacks on non-South African Africans during May 2008. In a report in The Times (17 June 2008) under the title Mandela calls for 'Social cohesion', former president Nelson Mandela urged the youth of South Africa to work for social cohesion in the country. "The struggle for democracy has never been a matter pursued by one race, class, religious community or gender among South Africans. As future leaders of this country, your challenge is to foster a nation in which all people, irrespective of race, colour, sex, religion or creed, can ascertain a social cohesion fully," (http://www.TheTimes-Mandela calls for 'social cohesion'.htm). My perspective regarding humans is, to paraphrase the late Clyde Kluckhohn, that: Every human is like all other humans, some other humans and no other human.
