Improving the GNSS positioning stochastic model in the presence of ionospheric scintillation
(Springer, 2009-10-01)
Ionospheric scintillations are caused by time-varying electron density irregularities in the ionosphere, occurring more often at equatorial and high latitudes. This paper focuses exclusively on experiments undertaken in ...
Passageiros de terceira classe: o transporte de emigrantes na história econômica da Navigazione Generale Italiana
(2013)
From the 1860s, the Italian emigration reached many entily, becoming on national problem and a source of revenue for shipping companies operating in the Atlantic. In Italy, the resources were fundamental in financing the ...
On-line SLAM using clustered landmarks with omnidirectional vision
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2010)
The problem of SLAM (simultaneous localization and mapping) is a fundamental problem in autonomous robotics. It arises when a robot must create a map of the regions it has navigated while localizing itself on it, using ...

Semantic mapping using mobile robots
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Robotic mapping is the process of automatically constructing an environment representation using mobile robots. We address the problem of semantic mapping, which consists of using mobile robots to create maps that represent ...
Logical Methods in Computer Science
(2015)
Graph data models have recently become popular owing to their applications, e.g., in social networks and the semantic web. Typical navigational query languages over graph databases - such as Conjunctive Regular Path Queries ...
Quality of TEC Estimated with Mod Ion Using GPS and GLONASS Data
(Hindawi Publishing Corporation, 2009-01-01)
One of the largest sources of error in positioning and navigation with GNSS is the ionosphere, and the associated error is directly proportional to the TEC and inversely proportional to the square of the signal frequency ...
