This study adopted a Geographic Information Systems (GIS) approach to map and assessed the geographic distribution of plastic waste recycling facilities in Kano Metropolis. Specifically, aimed at creating an inventory for Metropolis investigating its pattern. Data collected on centers were obtained from State Ministry Commerce field survey. Global Positioning System (GPS) was then utilized reco...

With the growing availability of large volumes of textual information on the Web, text mining techniques have been gaining a growing interest. One specific text mining problem that is increasingly relevant relates to the detection of textual expressions that refer to opinions on certain topics and services. A second text mining problem, which has also been gaining a growing interest, is the ide...

Ultra low frequency (ULF) wave activity in the high-latitude ionosphere has been observed by a high frequency (HF) Doppler sounder located at Tromsù, Norway (69.7°N, 19.2°E geographic coordinates). A statistical study of the occurrence of these waves has been undertaken from data collected between 1979 and 1984. The diurnal, seasonal, solar cycle and geomagnetic activity variations in occurrenc...

This paper describes a prototype application to use different algorithms for creating optimal evacuation routes in the presence of wildfire with dynamic event-based update. The uses meteorological API that obtains real-time temperature, atmospheric pressure, humidity, speed, and wind direction each location within an area using geographic coordinates (latitude longitude) sensor network. data ar...

Scientists engaged in the research of natural products often either conduct field collections themselves or collaborate with partners who do, such as botanists, mycologists, or SCUBA divers. The information gleaned from such collecting trips (e.g. longitude/latitude coordinates, geography, elevation, and a multitude of other field observations) have provided valuable data to the scientific comm...

September 2013 769 Recent IT technologies and online services are tremendously altering the way people create, use and share geographic information (Elwood, 2008). Enabled by the widespread use of hand-handled GPS, geo-tags, high-resolution graphics and access to the Internet and Web 2.0, spatial data can be collected and produced voluntarily by the untrained general public. This has been terme...

As wireless sensor networks continue to grow in size, we are faced with the prospect of emerging wireless networks with hundreds or thousands of nodes. Geographic routing algorithms are a promising alternative to tradition ad hoc routing algorithms in this new domain for point-to-point routing, but deployments of such algorithms are currently uncommon because of some practical difficulties. Thi...

The increased usage of mobile devices, equipped with digital cameras, has allowed users to take photographs and share them more easily and more quickly than in the past. Everyday thousands, if not hundreds of thousands, of photos are uploaded to social networking websites using computers and mobile devices. It has been said that "a picture is worth a thousand words" but now we must consider the...

Biogeographic patterns of survival help constrain the causal factors responsible for mass extinction. To test whether biogeography influenced end-Cretaceous (K-Pg) extinction patterns, we used a network approach to delimit biogeographic units (BUs) above the species level in a globalMaastrichtian database of 329 bivalve genera. Geographic range is thought to buffer taxa from extinction, but the...

We carry out a sequence of coordinate changes for the planar three-body problem which successively eliminate the translation and rotation symmetries, regularize all three double collision singularities and blow-up the triple collision. Parametrizing the configurations by the three relative position vectors maintains the symmetry among the masses and simplifies the regularization of binary colli...
