The Beginning Of A New Era In Design: Calibrated Discrete Element Modelling, Andrew Grima, David Hastie, David Curry, Peter Wypych, Richard La Roche
The Beginning Of A New Era In Design: Calibrated Discrete Element Modelling, Andrew Grima, David Hastie, David Curry, Peter Wypych, Richard La Roche

The reliable storage and flow of bulk materials requires a comprehensive design process and good understanding of the flow properties of a bulk material. Analytical and empirical design techniques form the backbone of many design processes as they have been validated by research, however, theories based on continuum mechanics have many shortcomings and are restricted to 2-D analysis. Discrete element modelling (DEM) is proving to be a popular analysis and simulation method to verify designs for a wide range of bulk material processing and handling operations, such as transfer chutes. With the advances in computing and DEM technology, DEM has …

Conveyor transfer stations play a key role in many industries that handle bulk materials. Transfer stations can be rather sensitive to changes in material properties and can lead to relentless problems regarding reliability, wear, bottlenecking and blockages. Wet and sticky ores are typically difficult to handle materials due to their obnoxious ability to form a cohesive arch, adhere to surfaces and poor flow ability. Mines that are situated in areas with seasonal high rainfalls or that have started to exploit newer and more difficult to mine and handle ores, often from below the water table, experience vast difficulty in reliably …

An Adaptive Design Approach For Geothermal Plant With Changing Resource Characteristics, M Imroz Sohel, Mathieu Sellier, Susan Krumdieck

Geothermal power plants are designed for optimal utilization of geothermal resource. However, geothermal fields typically undergo significant changes in resource characteristics such as pressure, temperature and steam quality over their life span. With appropriate reservoir modelling it is possible to predict the future resource characteristics of a geothermal field to a reasonable degree of accuracy. We propose a new adaptive design approach that would allow geothermal power plants to take into account the change of resource characteristics that occur over a 30-40 years time horizon based on the results of reservoir modelling. Currently, it is difficult and expensive to modify …
Value Co-Creation With Customers Through Design Toolkits: The Importance Of Preference Fit And Psychological Ownership, Tingru Cui, Hua Ye, Hock Hai Teo
Value Co-Creation With Customers Through Design Toolkits: The Importance Of Preference Fit And Psychological Ownership, Tingru Cui, Hua Ye, Hock Hai Teo

The information technologies increasingly enable companies to set up websites for customers to design and purchase their own individualized products. Although customer co-design offer benefits for both suppliers and customers, how to manage the co-design process, especially the central interface features of design toolkit have emerged as a contentious issue among researchers and practitioners. This paper focuses on the effects of both utilitarian and psychological customer-design product value (i.e., perceived preference fit and psychological ownership) on customers' purchase decision. Based on the self-determination theory, we propose that the effectiveness of the value increment mechanisms is influenced by three leading toolkit …
