Concentrations of PM10, PM2.5 and PM1 were monitored at 24 CAWNET (China Atmosphere Watch Network) stations from 2006 to 2014. The highest particulate matter (PM) concentrations were observed at the stations of Xian, Zhengzhou and Gucheng, on the Guanzhong Plain and the Huabei Plain (HBP). The second highest PM concentrations were observed in northeast China, followed by southern China. Accordi...

We develop a model to optimize the location of public fast charging stations for electric vehicles (EVs). A difficulty in planning the placement of charging stations is uncertainty in where EV charging demands appear. For this reason, we use a stochastic flow-capturing location model (SFCLM). A sample-average approximation method and an averaged two-replication procedure are used to solve the p...

BACKGROUND In this brief report, we describe two ways in which we assessed the Scholar CanMEDS role using a method to measure residents' ability to complete a critical appraisal. These were incorporated into a modified OSCE format where two stations consisted of 1) critically appraising an article and 2) critiquing an abstract. METHOD Residents were invited to participate in the CanMEDS In-Tr...

The data used in developing the frequency relations consisted of both daily and hourly precipitation records from Illinois and from nearby stations in surrounding states. The daily data, mostly from nonrecording raingages, spanned the 83-year period from 1901 through 1983. They included data from the 61 precipitation-reporting stations discussed previously (figure 71, whose records had been car...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S aureus (MSSA) were isolated from environment surfaces sampled from 33 Washington State fire stations. METHODS Samples were collected by fire personnel using commercial testing swabs. One to 6 surfaces were sampled per swab with 20 swabs per station. Biochemical tests were used to confirm MRSA and MSSA ...

OBJECTIVES To locate the road emergency stations in Fars province based on using spatial multi-criteria decision making (Delphi method). METHODS In this study, the criteria affecting the location of road emergency stations have been identified through Delphi method and their importance was determined using Analytical Hierarchical Process (AHP). With regard to the importance of the criteria an...

This article presents a distributed real-time control system for the southern grid of the Cameroon power system. The southern grid, which supplies over 90 % of the power output in Cameroon, incorporates two remotely located hydro-electric generating stations, a power distribution center, several thermal plants and hundreds of kilometers of transmission lines. The proposed distributed control sy...

The next deployments of IEEE 802.11 WLAN will involve the coexistence of the legacy best effort stations and the new recently standardised QoS-aware stations in QoS Basic Service Set (QBSS). However, if no control is applied to the legacy stations, this coexistence may deteriorate QoS support provided by the new IEEE 802.11e standard. In this paper the influence of IEEE 802.11b DCF stations on ...
