 In the modern world where technology and information systems are a dire for every sectors improvement, tourism industry can also not progress without them. Geographic Information Systems (GIS) helps identify potential resources located, their distribution, about them associated characteristics. Beyond providing cartographic applications, GIS plays an essential role in comfort effectivene...

The effect of base temperature variation on the heat transfer from unsteady state annular heat sink of cooling microelectronic device. Three types of the base temperature variation equations are taken in the present study. The Sine wave variation, Cosine wave variation & exponential variation of the base temperature. The finite element technique based on Galerkin method with axisymmetric rectan...

In recent years remote sensing (RS), geographic information systems (GIS) and global positioning systems (GPS), have been three main technologies for spatial information acquisition, spatial data storage management, spatial data updating, spatial analysis and applications. However, the integration of the three technologies is an important issue and a big challenge to the geo-information communi...

Development of wireless sensor network equipped with GPS for post-seismic building-wise damage identification is presented in this paper. This system is called GPS on Every Roof. Sensor node equipped with GPS antenna and receiver is installed on the top of the roof of each and every building. The position of this sensor node is measured before and after earthquake. The final goal of this system...

The use of GPS devices in health research is increasingly popular. There are currently no best-practice guidelines for collecting, processing, and analyzing GPS data. The standardization of data collection and processing procedures will improve data quality, allow more-meaningful comparisons across studies and populations, and advance this field more rapidly. This paper aims to take researchers...

We propose a method to improve object detection results by introducing GIS data into the fold. Our current system uses post-processing techniques on the object detection results to get rid of most of the false positive detections and acquire some of the true positives. We show that GIS data can greatly improve object detection results on images which have a GPS tag of where the image was taken ...

This paper reports findings from an AHRC-funded project into the use of more than one language in research projects. Using 35 seminar presentations and 25 researcher profiles, we investigated how researchers from differing disciplines became aware of the possibilities, complexities, and emerging practices of researching where more than one language is used: for example, in initial research desi...
