A mathematical model has been developed to determine the timing of the tasks that can be performed on a variety of units to produce a variety of end states and to monitor the flow of the material through the network. The mathematical model is based on the work of Kondili et al. (1993) and is extended with the ability to monitor and restrict the...

A pilot-scale PHA microbial enrichment reactor fed on OFMSW leachate was monitored in order to assess the influence of free ammonia nitrogen (FAN) on its performance. The enrichment reactor consisted of a SBR with a 12-hours cycle which included a feast phase, a settling phase and a famine phase with external nitrogen addition. Based on the...

As freshwater resources are predicted to become more scarce in the future, desalination will become a more prevalent treatment method. Microbial desalination, defined as the use of microbial processes to remove ions from a saline solution, may have potential as a new desalination method to produce water for domestic, agricultural or industrial...

With the growing population and industrial development, there is more stress on natural water resources. Additionally, environmental laws make the disposal of waste streams from industries difficult. In this scenario, it is crucial to treat waste streams to recover water and possibly minerals, for reuse in the industry, reducing the dependency...

Nowadays in large-scale process industry, high purity of products is not only desired but crucial. Products must meet high-purity standards to conform with market and customers’ requirements. Two chemical processes, reaction and distillation, are essential to achieve these objectives. To overcome certain disadvantages and/or limitations that...

In oil supply chains, crude oil needs to be transported from oil fields to refineries, and refined products need to be transported from refineries to regional depots. On land, pipelines are the preferred mode for long-distance oil transportation, because they are safe, efficient, silent, and cheap compared to other modes of transport. Pipelines...

Collaboration in the supply chain is nowadays seen in the scientific community as the “next best thing” in supply chain optimization (Ballot, 2015; Barratt & Oliveira, 2001; Barratt, 2004; Ireland & Bruce, 2000). Although widely investigated and often mentioned in literature, the concept of supply chain collaboration is not precisely defined ...

The production of anodes at Aluchemie is improved using a genetic algorithm. This is a parallel batch scheduling problem, where the batching and handling time constraints are predetermined. The GA has customized crossover and mutation functions. Using this GA, an improvement of 4.4% achieved.

Sensing in smartphones consumes a significant amount of energy and leads to quick depletion of the battery. Most of the existing solutions to overcome the short battery lifetime caused by periodic sensing are personalized. They tend to learn and predict the user activities. Thus, fewer samples are required to recognize user state and sensing...

Tsompanopoulos, E. (author)
Based on satellite observations of Earths time variable gravity field from the Gravity Recovery and Climate Experiment (GRACE), it is possible to derive variations in terrestrial water storage. Tiny variations of gravity from monthly into a decade time scales are mainly due to redistributions of water mass inside the surface fluid envelops of...
