Knowledge representation in robotics is a challenging problem. Both the chosen abstraction and the type of information, in fact, may affect the performance of the robot. In particular, a key problem to take into account is symbol grounding, since the symbols used in the representation need to be connected to the proper elements of the operational environment. In the case of robots that operate ...

Today, historians, philosophers, and scholars of cultural heritage discuss about the relationship between periodizing labels historiography their symbolic employment within current political rhetoric. To understand relevance this issue in Italy, it can be helpful to look at academic public debates around category “Renaissance”. On one hand, article aims map some notable uses historical figure a...

Orthogonal Modulation and FEC Rupert Herzog, Andreas Schmidbauer and Joachim Hagenauer Department of Communications Engineering (LNT), Technical University of Munich (TUM), Arcisstr. 21, D-80290 Munich, Germany email: frupert, andreas, [email protected] ABSTRACT: Iterative decoding is applied to code division multiple access (CDMA) systems with two-stage serial concatenated chan...

Minimum distance (MD), maximum likelihood (ML), and maximum a posteriori (MAP) decoding is considered for synchronization error correcting (SEC) codes with known codeword boundaries when transmitted over the Binary Substitution, Insertion and Deletion channel. It is shown that MD decoding is sub-optimal, unlike ML or MAP decoding. Based on ML and MAP decoding, a new measure called the Change Pr...

Introduction: Optimum symbol decision algorithms for digital transmission must base their decisions on the maximum a posteriori (MAP) probability. They have been known since the early seventies [l], although they are much less popular than the Viterbi algorithm and almost never applied in practical systems. Only re cently interest in these algorithms has been revived, in connection with the pro...

There is reason to suspect that 4C 41.17, a radio galaxy at z = 3:800 0:003, contains a large quantity of enriched molecular gas. We describe a search for CO in 4C 41.17, taking advantage of the fact that the J = 1 ! 0 rotational transition is redshifted into the radio-frequency band centred at 23 GHz for 3:80 < z < 4:25. There is no sign of CO line emission in our resulting spectrum, which cov...

Direct application of network coding at the physical layer physical layer network coding (PNC) is a promising technique for two-way relay wireless networks. In a two-way relay network, relay nodes are used to relay two-way information flows between pairs of end nodes. This paper proposes a precise definition for PNC. Specifically, in PNC, a relay node does not decode the source information from...

GlobeLand30 is the world’s first global land cover dataset at 30 m resolution for two epochs, i.e., 2000 and 2010. On the official website, the data are represented by qualitative thematic maps which show the distribution of global land cover, and some proportional symbol maps which are quantitative representations of land cover data. However, researchers have also argued that the cartogram, a ...

Abstract. We consider the inverse boundary value problem for the system of equations describing elastic waves in isotropic media on a bounded domain in R via a finite-time Laplace transform. The data is the dynamical Dirichlet-to-Neumann map. More precisely, using the full symbol of the transformed Dirichlet-to-Neumann map viewed as a semiclassical pseudodifferential operator, we give an explic...
