Understanding how users tailor their SPARQL queries is crucial when designing query evaluation engines or ne-tuning RDF stores with performance in mind. In this paper the authors analyze 3 million real-world SPARQL queries extracted from logs of the DBPedia and SWDF public endpoints. They aim at finding which are the ...Download Now
Nowadays, a variety of information related to the distance between two wireless devices can be easily obtained. This paper presents a hybrid localization scheme that combines Received Signal Strength (RSS) and Round-Trip Time (RTT) information with the aim of improving the previous localization schemes. The hybrid localization scheme is based ...Download Now
The presence of (Non Line Of Sight) NLOS propagation paths has been considered the main drawback for localization schemes to estimate the position of a (Mobile User) MU in an indoor environment. This paper presents a comprehensive wireless localization system based on (Round-Trip Time) RTT measurements in an unmodified IEEE ...Download Now
