Many activated sludge wastewater treatment control strategies have been proposed in the literature; however, the literature does not provide a clear basis for comparison of these strategies because of the many confounding influences that have an impact on the system. Complicating the evaluation is the lack of standard evaluation criteria. Simulations provide a cost-effective means for the evaluati

Pharmacists must ensure that patients know how to make the best use of their medication. An education programme was initiated in the southernmost part of Sweden during 1990 in order to improve the communication skills of pharmacy staff and the information given to customers. Customers with prescriptions for Turbuhaler were asked to 'show-and-tell' how they used their inhalers, and the results were

Massive MIMO has been shown, both in theory and through experiments, to offer very promising properties. These include the possibility to decrease output power by at least an order of magnitude while still achieving large gains in spectral efficiency, as compared to today’s access schemes. To efficiently design communication algorithms and evaluate massive MIMO schemes, channel models that capture

To remain effective within the public procurement proc-ess it is important to avoid revisions on contract award deci-sions, which prolong the procurement process and takes its toll on public resources. This paper aims to delineate the grey zone within public procurement legislation and clarify how the court interprets it, which will aid procurement officers in achieving best practice. Findings ind

Outdoor positioning systems are commonly available and typically rely on satellite navigation. The same is not true for indoor positioning systems. Severe multipath, non line-of sight to satellites and moving objects are some of the aspects that make the task of indoor positioning tricky. In this paper, we analyse different tracking methods to estimate and track the delay evolution of a radio chan
