Data Acquisition and Control Software for Automated Resistivity Measurements (2014)
Presentation / Conference Contribution
Toll, D., & Hassan, A. (2014, July). Data Acquisition and Control Software for Automated Resistivity Measurements. Presented at 2nd International Conference on Information Technology in Geo-Engineering, Durham, UK

Automated multi-electrode resistivity systems now allow rapid and efficient data acquisition of electrical resistivity measurements to address a wide range of hydrogeological, geotechnical and environmental problems. In this work, a flexible data acq... Read More about Data Acquisition and Control Software for Automated Resistivity Measurements.

Data Acquisition Software for Controlling Serial Ports with Cloud Data Storage (2014)
Presentation / Conference Contribution
Asquith, J., & Toll, D. (2014, July). Data Acquisition Software for Controlling Serial Ports with Cloud Data Storage. Presented at 2nd International Conference on Information Technology in Geo-Engineering, Durham, UK

A common requirement of laboratory and field data collection is for automated data logging software to control instrumentation and report on the results. Large projects may require a range of different instrumentation each with its own preferred meth... Read More about Data Acquisition Software for Controlling Serial Ports with Cloud Data Storage.

Soil atmosphere interactions for analysing slopes in tropical soils (2014)
Presentation / Conference Contribution
Toll, D., Rahim, M. M., Karthikeyan, M., & Tsaparas, I. (2014, September). Soil atmosphere interactions for analysing slopes in tropical soils. Presented at The 14th International Conference of the International Association for Computer Methods and Advances in Geomechanics, Kyoto, Japan

Modelling of soil-atmosphere interaction for slopes requires a proper understanding of the soil parameters (soil retention curve and the permeability function). This paper reports on numerical investigations of an instrumental residual soil slope in... Read More about Soil atmosphere interactions for analysing slopes in tropical soils.

Information Technology in Geo-Engineering (2014)
Book
Toll, D., Zhu, H., Osman, A., Coombs, W., Li, X., & Rouainia, M. (Eds.). (2014). Information Technology in Geo-Engineering. IOS Press

Information technology continues to evolve and remains central to all aspects of geo-engineering. Key issues are the effective use and re-use of data, particularly within Building Information Modelling (BIM) frameworks; the use of smart monitoring; a...

Investigation of the directional dependence of soil resistivity in cracking clays (2014)
Presentation / Conference Contribution
Hassan, A., & Toll, D. (2014, July). Investigation of the directional dependence of soil resistivity in cracking clays. Presented at 6th International Conference on Unsaturated Soils, Sydney, Australia

Electrical resistivity is a physical property that defines how a material resists the flow of electricity. The resistivity method is therefore based on the principle that the potential drop across a pair of electrode (P1 and P2) associated with DC or...

Interpretation of stresses and strains in unsaturated fine-grained soils (2014)
Presentation / Conference Contribution
Murray, E., Toll, D., & Sivakumar, V. (2014, July). Interpretation of stresses and strains in unsaturated fine-grained soils. Presented at 6th International Conference on Unsaturated Soils, Sydney, Australia

The derivation of Eq. (1) relies on the soil particles and water phase combining and forming aggregates under equilibrium conditions. This may be shown to minimise the thermodynamic potential and is a requirement of equilibrium conditions. The equati...
