MacEwan University Wi-Fi Analysis
MacEwan Unversity has recently upgraded its wireless infrastructure on campus. The goal was to determine whether or not wireless bandwidth speeds were consistent across an area of the school, and if they were not, which areas had the strongest and weakest connections. The results could be taken as a reflection of the new system’s effectiveness and coverage. To assess wireless bandwidth speeds, both the upload and download speeds were measured across regions of the campus library using the mobile app Speedtest.net by Ookla which downloads chunks of data to a mobile device to measure connection speed. To ensure that the samples were representative, speeds were measured through various times of the day and different days of the week. These temporal dimensions were used as blocks in the experimental design. Preliminary data collection also indicated a significant difference in mobile device used, and so the use of either Apple’s iPhone 6 or Samsung’s Galaxy S3 was also selected as a block in order to prevent the age of the device becoming a nuisance factor in the experiment. In the end, the results indicated that wireless speeds were inconsistent across the library. The results provided a heat map which showed that some areas had a significantly higher bandwidth speed than other areas. The results of this study could be used to plan future changes to wireless router layout and influence new infrastructure decisions. In addition, the research methodology could be further developed and extended to any Wi-Fi or cellular service.

An Ecological Analysis of the Potential for Moss-Based Green Roof Design
Green roofs are a maturing application of best management practices for
controlling urban stormwater runoff. The majority of green roofs are planted with
drought resistant, higher plant species, such as the genus Sedum. However, other plant
varieties, such as mosses, may be equally applicable. Residential roofs and natural
terrestrial communities were sampled in both Maryland and Tennessee to determine moss
community structure and species water composition. This served as a natural analog for
potential green roof moss communities. During sampling, 21 species of moss were
identified throughout the 37 total sites. The average percent moss cover and water
composition across all roof sites was 40.7% and 38.6%, respectively and across all
natural sites, 76.7% and 47.7%, respectively. Additional maximum water holding
capacity procedures were completed on sedum and 19 of the 21 sampled moss species to
assess their individual potential for stormwater absorption. Sedum species on average
held 166% of their biomass in water, while moss species held 732%. The results of this
study are used as a basis to propose moss species that will improve green roof
performance
