Massive Quasi-Clique Detection
- In Latin American Theoretical Informatics (LATIN
, 2002
"... We describe techniques that are useful for the detection of dense subgraphs (quasi-cliques) in massive sparse graphs whose vertex set, but not the edge set, fits in RAM. The algorithms rely on efficient semi-external memory algorithms used to preprocess the input and on greedy randomized adaptive se ..."

"... when the channel is under the effect of log-normal shadowing. Specifically we propose a distributed power conserving PU detection architecture and investigate the impact of PU detection accuracy on DSAN performance. We measure DSAN blocking probability as a function of the number of PU channels and ..."

Revision: final Dissemination level: PU
"... This report presents the results of WP2 for the third year of NIFTi. Vision plays an essential role in the robot perception and also serves as the primary source of information for robot tele-operation. We focused on vision for shared situation awareness (MS2.3). We contributed in machine learning f ..."

for image understanding, object detection, navigation and orientation, and human/fire detection. We developed an algorithm for measuring terrain profile and applied it on automatic flipper control based. Machine learning approach was adopted for terrain classification from vibrations. We added thermal
Revision: final Dissemination level: PU
"... One of the main objectives of NIFTi is to have an Unmanned Ground Vehicle (UGV) explore a disaster area. This requires specific motion capabilities around which the NIFTi UGV has been designed. Additionally to these physical capabilities, controlling robot motion in unstructured and uneven terrain i ..."

Revision: final Dissemination Level: PU
"... Revision final This report presents a summary of our results on tracking and identification of humans from a mobile robot in everyday environments. The report starts with a short analysis of the sensor sources that can be used for human tracking from a mobile robot. The report is continued with a su ..."

summary our results on fast and robust people tracking using vision and other sensor sources. This summary is based on a number of published or submitted scientific reports. First, we present some results on detection and tracking of people using only vision. We analyze and propose an improved motion

"... Short-lived nuclides, now extinct in the solar system, are expected to be present in interstellar matter (ISM). Grains of ISM origin were recently discovered in the inner solar system and at Earth orbit and may accrete onto Earth after ablation in the atmosphere. A favorable matrix for detection of ..."
