A large single-year reversal in the phase of the North Atlantic Oscillation (NAO) during 1996 led to a dramatic shift in the slope-water circulation patterns of the northwest (NW) Atlantic. Analyses of time-series data collected from the region over the past half century show that both physical and biological responses are commonly elicited by such phase reversals in the NAO. Here, we use a mod...

We propose two real-time sound recognition approaches that are able to distinguish a predefined whistle sound on a NAO robot in various noisy environments. The approaches use one, two, and four microphone channels of a NAO robot. The first approach is based on a frequency/band-pass filter whereas the second approach is based on logistic regression. We conducted experiments in six different sett...

We describe an integrative cognitive architecture for human-like, human-level, embodied general intelligence, founded on integrating the OpenCogPrime framework for cognition, language and high-level learning with a hierarchical temporal memory for lower-level perception and action. The core conceptual principle of the architecture is ”cognitive synergy”, wherein different components are specifi...

A general perceptual model is proposed for Eldercare Robot implementation that is comprised of audition functionality interconnected with a feedback-driven perceptual reasoning agent. Using multistage signal analysis to feed temporally tiered learning/recognition modules, concurrent access to sound event localization, classification, and context is realized. Patterns leading to the quantificati...

Phthalocyanine (Pc) 4, like many photosensitizers for photodynamic therapy (PDT), localizes to intracellular membranes, especially mitochondria. Pc 4-PDT photodamages Bcl-2 and Bcl-xL, antiapoptotic proteins interacting with the permeability transition pore complex that forms at contact sites between the inner and outer mitochondrial membranes. These complexes and the inner membrane are unique ...

The main goal of this paper is to analyze the general problem of using Convolutional Neural Networks (CNNs) in robots with limited computational capabilities, and to propose general design guidelines for their use. In addition, two different CNN based NAO robot detectors that are able to run in real-time while playing soccer are proposed. One of the detectors is based on the XNOR-Net and the ot...

In this paper we introduce an online object manipulation system for the NAO robot that is able to detect and grasp an object out of a human hand and then give it back in real-time. Known objects are rendered from 3D models and detected stereo contour-based by using a new stereo vision head for NAO. In order to grasp objects, motion trajectories are generated by an A* planner while avoiding obst...

We are addressing the problem of creating empathic robot tutors to support school students studying geography topics on a multitouch table. A multi-role serious game Enercities-2 has been developed from an earlier single-user version in which a Mayor, Economist and Environmentalist have control over differing resources. The game explores the tension between individual and collaborative success....
