An auto-switch for multisampling of a wire beam electrode corrosion monitoring system

An auto-switch device has been designed, constructed, and tested for multisensor corrosion measurements. The auto-switch is able to connect/disconnect the selected wire beam electrode and/or electrode pairs under computer control. A computer controlled analog switch-array consisting of 100 inputs has been used as an essential part of the switch bank. The switch-bank is an essential component of a corrosion-monitoring instrument that is expected to find wide application in industry. The performance of the switch-bank is discussed and its effect on the signals is illustrated.

A sequence based dynamic SOM model for text clustering

Text clustering can be considered as a four step process consisting of feature extraction, text representation, document clustering and cluster interpretation. Most text clustering models consider text as an unordered collection of words. However the semantics of text would be better captured if word sequences are taken into account.

In this paper we propose a sequence based text clustering model where four novel sequence based components are introduced in each of the four steps in the text clustering process.

Experiments conducted on the Reuters dataset and Sydney Morning Herald (SMH) news archives demonstrate the advantage of the proposed sequence based model, in terms of capturing context with semantics, accuracy and speed, compared to clustering of documents based on single words and n-gram based models.

Narrative inquiry and auto-ethnography: Interpretive approaches to research

Hermeneutic phenomenology informed two qualitative methodologies used in my doctoral research: narrative case studies and auto-ethnography. Through these methodologies I investigated the phenomenon of place and identity in visual artistic practice. Four narrative case studies of four artists were developed using experience-focused narrative inquiry and thematic analysis. Auto-ethnography was used to investigate the phenomenon of place and identity within my own practice as visual artist. This involved analysis of my artworks that encompassed place and identity and writing from different contexts of my past. Rather than relying on memory recall. This became textural writing in the phenomenon rather than describing what I already knew. This enabled me to challenge conventional ways of telling my story (big stories) and produced “small stories” from which new insights could be interpreted. The insights gained from my auto-ethnography in turn assisted me to encourage story telling to find the small stories of my artist participants.

Auto-amputation of the tongue associated with flupenthixol induced extrapyramidal symptoms.

We report a case of tongue auto-amputation in a mentally retarded patient after a flupenthixol injection. Four days after flupenthixol administration, the patient developed orolingual dyskinetic movements involving mainly tongue biting and protrusion. Self-mutilation in this case may be secondary to flupenthixol induced acute atypical orolingual dyskinesia in the face of mental retardation.
