The tools and standards of best practice adopted by natural science (NS) and cultural heritage (CH) professionals will determine the digital future of NS and CH digital imaging work. This tutorial discusses emerging digital technologies and explores issues influencing widespread adoption of digital practices for NS and CH. The tutorial explores a possible(More)
The amount of information that can be retained in working memory (WM) is limited. Limitations of WM capacity have been the subject of intense research, especially in trying to specify algorithmic models for WM. Comparatively, neural circuit perspectives have barely been used to test WM limitations in behavioral experiments. Here we used a neuronal(More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract This paper explores the coupling of the Perfectly Matched Layer technique (PML) with the Thin Layer Method (TLM), the combination of which allows making highly efficient and accurate simulations of layered half-spaces of infinite(More)
This paper proposes a localization system for a mobile robot based on odometric data and RGB-D (Red, Green, Blue image and Depth map) measurements relative to a landmark, available from sensors installed on board. The localization system is composed of two cascaded estimators: i) a kinematic optimal attitude estimator; and ii) a position This work was(More)
Abstract This paper explores the coupling of the Perfectly Matched Layer technique (PML) with the Thin Layer Method (TLM), the combination of which allows making highly efficient and accurate simulations of layered half-spaces of infinite depth subjected to arbitrary dynamic sources anywhere. It is shown that with an appropriate complex stretching of the(More)
Portus Legged League team is being developed by a research group with a long and successful experience in RoboCup (simulation, small-size and middle-size leagues) and results from the combined efforts of two research laboratories (LIACC and ISR-P) and from our previous teams (FC Portugal – simulation league and 5DPO – small and middle size leagues). We(More)
