Glove prototype for feature extraction applied to learning by demonstration pur...
Cerqueira, Tiago; Ribeiro, Francisco; Pinto, Vítor H.; Lima, José; Goncalves, GilThis article focuses on a sensorial glove prototype capable of acquiring hand motion and estimating its pose. The presented solution features twelve inertial measurement units (IMUs) to track hand orientation. The sensors are attached to a glove to decrease the project cost. The system also focuses on sensor fusion algorithms for the IMUs and further implementations, presenting the algebraic quaternion algorith...
Contribuição sobre o setor bancário
Cerqueira, TiagoA presente dissertação apresenta como objeto de estudo a Contribuição sobre o sector Bancário e sua legalidade. Esta serve como principal financiadora do Fundo de Resolução, que têm como função prestar apoio financeiro às instituições bancárias. A CSB advém de várias diretrizes europeias que discutiam a criação de uma “taxa” que pudesse ser aplicada a todas as instituições financeiras, para que no caso de crise...
A module for the FTT-SE protocol in ns-3
Oliveira, Fábio; Martínez, Ricardo Garibay; Cerqueira, Tiago; Albano, Michele; Ferreira, Luís LinoThe Flexible Time Triggered Switched Ethernet (FFT-SE) protocol allows the concurrent transmission of both real-time (i.e., synchronous and asynchronous) traffic and best-effort traffic over Ethernet. Communications within an FTT-SE network are done based on the reservation of fixed duration time slots called Elementary Cycles (ECs). The construction of the ECs and the media access control are managed by the ma...
A module for the XDense architecture in ns-3
Loureiro, João; Albano, Michele; Cerqueira, Tiago; Rangarajan, Raghuraman; Tovar, EduardoThe acquisition of data regarding some dynamic phenomena can require extremely dense deployments of sensors and high sampling rates. We propose XDense [1], a wired mesh grid sensor network architecture (see Figure 1a) tailored for scenarios that benefit from thousands of sensors per square meter. XDense has scalable network topology and it enables complex feature extraction in real-time from the observed phenom...
RoutesMobilityModel: easy realistic mobility simulation using external informat...
Cerqueira, Tiago; Albano, MicheleThe current implementation of ns-3 provides only synthetic mobility models that disregard the map where the nodes are moving, however, the study of vehicular ad-hoc networks requires the usage of more realistic mobility models. The usage of mobility traces created by traffic simulators such as SUMO is feasible, however, these simulators possess a steep learning curve, which prevents their fruition for most rese...

A module for Data Centric Storage in ns-3
Albano, Michele; Cerqueira, Tiago; Chessa, StefanoManagement of data in large wireless sensor networks presents many hurdles, mainly caused by the limited energy available to the sensors, and by the limited knowledge of the sensors regarding the topology of the network. The first problem has been targeted by the introduction of in-network storage of sensed data, which can save much communication energy. The second issue found some relief with the introduction ...
