Poset metrics where first introduced by Brualdi et al. in 1998, generalizing on the work of Niederreiter in 1995. Applications for these metrics, a generalization of the classical hamming metric, include: describing the noise process in a wireless fading system, its use for unequal error protection, applications for decoding in parallel wiretap channels. Computing invariants os such metri…
This project addresses two specific instances in the coding universe, contexts in which the visiting researcher already has previous experience.The first of these is the use of tiling in the hyperbolic plane, or a choice of an hyperbolic lattice, for the development of high density signal constellations (making them suitable for quantization information), which are associated with the gro…

In this project, we intend to analyze to what extent the material Self-corrective Workbooks: Fractions, developed by a team from the Teaching Residency Program of the Licentiate in Mathematics course at Unicamp, contributes to a better conceptual understanding of fraction-related contents, allowing the overcoming of the most prevalent misconceptions. We intend to develop this analysis in …
Error-correcting and cryptographic codes are areas of interface between the subjects of Mathematics, Electrical Engineering and Computer Science. Due to this interdisciplinary nature, with the support of FAPESP through the Thematic Project Security and Reliability of Information: Theory and Practice (Process Fapesp 2013 / 25977-7), we decided to set up a scientific initiation group with n…

Communications systems based in networks may be found in several contexts, some of them, such as the public Internet, the peer-to-peer networks and the wireless ad-hoc networks, have became central in our daily lives. Network coding was recently proposed as an alternative to the traditional approach (store-and-forward) in order to provide an improvement of the network throughput. When mul…
Networks play an important role in natural, social and economic phenomena. Methods derived from graph theory have been used to extract information of the networks, in order to predict the behavior of systems. For instance, social networks can be modeled by using threshold graphs. Ravanmehr et al., generalized such family with the aim of improving the extraction of interaction information …
One of the main goals of the theory of error correcting codes is to minimize the likelihood of errors in coding-transmission-decoding schemes. Considering semantic models for different types of errors that may occur (models that depend on the nature of the information to be transmitted) it becomes worthwhile to substitute the goal of minimizing the likelihood of errors by the goal of mini…
