Abstract With the development of information technology, research on hydropower stations intelligence has gradually become an important indicator for evaluation industry. Therefore, it is great significance to carry out intelligent transformation relevant equipment and systems in by integrating emerging technology. In view implementation content project gate control system a large station, this...

The lift station is becoming increasingly common as a component of the sewerage systems of Indiana. Cities and towns that have operated for years without the necessity of a lift station (other than one integral with sewage treatment plant) are finding it necessary to include a lift station in plans for extension of sewers. Those cities and towns which have not yet found it necessary to include ...

In this study, intraday correlations between station centralities and ridership at stations of the Athens metro system in Greece are explored. An unweighted L-space representation physical network is developed, degree, closeness betweenness selected as centrality measures. Hourly smart-card data used for representing passenger flows. For classification, principal component analysis k-means clus...

Energy efficiency in cellular networks is a growing concern for cellular operators to not only maintain profitability, but also to reduce the overall environment effects. According to technical analysts, the base stations are the most energy intensive part of a typical cellular network. Saving power in base stations is therefore the primary focus in energy efficient operation. The main goal of ...

It is common for hotspots in airports, cafes, and malls to deploy info-stations on their access points to provide local information such as flight schedule, multimedia access, sales and discount deals. The dissemination service, however, is limited by the wireless throughput in hotspots and cannot scale to a large number of users. This paper designs a new architecture that significantly improve...

The potential coupling of nitrogen (N2) fixation and sulfate reduction (SR) was explored in sediments of the Peruvian oxygen minimum zone (OMZ). Sediment samples were retrieved by a multiple corer at six stations along a depth transect (70–1025 m water depth) at 12 S, covering anoxic and hypoxic bottom water conditions. Benthic N2 fixation, determined by the acetylene reduction assay, was detec...

[1] Geomagnetically induced currents (GICs) can disrupt power grid operations, causing significant interference for many people; therefore, predictions of ground-based magnetic perturbations and their time derivatives are quite important. This study quantifies how well the University of Michigan’s Global MHD code predicts approximately 150 ground-based magnetometer traces for a number of storm-...

Factors conditioning formation and properties of suspended matter resting on the sea floor (Fluffy Layer Suspended Matter – FLSM) in the Odra river mouth – Arkona Deep system (southern Baltic Sea) were investigated. Thirty FLSM samples were collected from four sampling stations, during nine cruises, in the period 1996–1998. Twenty six chemical properties of the fluffy material were measured (or...
