An investigation of classification algorithms for predicting HIV drug resistance without genotype resistance testing

Author: Brandt, P ; Moodley, D ; Pillay, AW ; Seebregts, CJ ; De Oliveira, T Date: 2014 The development of drug resistance is a major factor impeding the efficacy of antiretroviral treatment of South Africa’s HIV infected population. While genotype resistance testing is the standard method to determine resistance, access to these ... Read more
IT infrastructure enabling open access for flood risk preparedness in South Africa

Author: Van Zyl, TL ; Parbhoo, C ; Moodley, D ; Cwela, B ; Umuhoza, D ; Shabangu, P ; Vahed, Anwar Date: May 2009 The paper focuses on the information technology infrastructure required for the evaluation and monitoring of risk relating to floods in South Africa. It may be argued that in the context of developing countries, flood preparedness is more ... Read more
A knowledge-based system for discovering ecological interactions in biodiversity data-stores of heterogeneous specimen-records: a case-study of flower-visiting ecology

Author: Coetzer, W ; Moodley, D ; Gerber, A Date: Nov 2014 We modeled expert knowledge of arthropod flower-visiting behavioral ecology and represented this in an event-centric domain ontology, which we describe along with the ontology construction process. Two smaller domain ontologies were created ... Read more
A knowledge-based system for generating interaction networks from ecological data

Author: Coetzer, W ; Moodley, D ; Gerber, A Date: Nov 2017 Semantic heterogeneity hampers efforts to find, integrate, analyse and interpret ecological data. An application case-study is described, in which the objective was to automate the integration and interpretation of heterogeneous, flower-visiting ... Read more
Knowledge-based system for the detection and classification of unplanned human settlements

Author: Parbhoo, C ; Moodley, D Date: Mar 2007 The discovery, access and sharing of suitable geospatial information in current open and distributed Spatial Data Infrastructures (SDI) still pose a major challenge. These problems usually stem from a lack of consistent semantics that is ... Read more
Modelling uncertain adaptive decisions: Application to KwaZulu-Natal sugarcane growers

Author: Price, Catherine S ; Moodley, D ; Pillay, AW Date: Dec 2019 A dynamic Bayesian decision network was developed to model the preharvest burning decision-making processes of sugarcane growers in a KwaZulu-Natal sugarcane supply chain and extends previous work by Price et al. (2018). This model was created ... Read more
New architecture for the sensor web: the SWAP framework.

Author: Moodley, D ; Simonis, I Date: Nov 2006 Sensor Web is a revolutionary concept towards achieving a collaborative, coherent, consistent, and consolidated sensor data collection, fusion and distribution system.
