Although reclaimed water for potable applications has many potential benefits, it poses concerns for chemical and microbial risks to consumers. We present a quantitative microbial risk assessment (QMRA) Monte Carlo framework to compare a de facto water reuse scenario (treated wastewater-impacted surface water) with four hypothetical Direct Potable Reuse (DPR) scenarios for Norovirus, Cryptospor...

Given a short term mining plan, the task for an operational mine planner is to determine how the equipment in the mine should be used each day. That is, how crushers, loaders and trucks should be used to realise the short term plan. It is important to achieve both grade targets (by blending) and maximise the utilisation (i.e., throughput) of the mine. The resulting problem is a non-linear sched...

The problem of how to plan coal fuel blending and distribution from overseas coal sources to domestic power plants through some possible seaports by certain types of fleet in order to meet operational and environmental requirements is a complex task. The aspects under consideration includes each coal source contract’s supply, quality and price, each power plant’s demand, environmental requirem...

Active teaching is increasingly accepted as a better option for higher education STEM courses than traditional lecture-based instruction. However, concerns remain regarding student preferences and the impact of increased course structure on teaching evaluations. Undergraduates in a non-majors neuropharmacology course were enrolled in an enriched blended course format, providing online case-base...

Stockpiling and blending play a major role in maintaining the quantity and quality of the raw materials fed into processing plants, especially the cement, iron ore and steel making, and coal-fired power generation industries that usually require a much uniformed feed. Due to the variable nature of such materials, they even come from the same source and the produced ores or concentrates are seld...

The paper reports work in progress on the investigation of the new ACT-R blending mechanism in its scope to account for data from two experiments with Broadbent’s TRANSPORTATION task. Two simple models are proposed that store and retrieve problem solving episodes to learn controlling the TRANSPORTATION scenario. Preliminary results with the models provide clear evidence for the empirical adequa...

The pooling problem is a nonconvex nonlinear programming problem (NLP) with applications in the refining and petrochemical industries, but also the coal mining industry. The problem can be stated as follows: given a set of raw material suppliers (inputs) and qualities of the supplies, find a cost-minimising way of blending these raw materials in intermediate pools and outputs so as to satisfy r...

The research on constructing algebraic blending surfaces between given surfaces is one of the most important problems in geometric modeling and computer graphics. To solve the problem better, this paper gives novel methods using theories of Gröbner bases to construct the required blending surfaces. According to the main theorems, we obtain the algorithms for constructing the blending surface, w...

To deal with the problem of high cost and low accuracy existed in conventional methods for the lead-zinc sintering blending, a qualitative and quantitative synthetic methodology for sintering blending optimization is presented in this paper. First, two prediction models are built based on a process neural network and the improved grey system theory. Next, these two models are integrated into on...
