We present a method for melody detection in polyphonic musical signals based on a model of the human auditory system. First, a set of pitch candidates is obtained for each frame, based on the output of an ear model and periodicity detection using correlograms. Trajectories of the most salient pitches are then constructed. Next, note candidates are obtained by trajectory segmentation (in terms o...

INTRODUCTION Robotic therapy, with its unique advantages over a human therapist, is an appealing option to minimize patients’ recovery time. Massed practice and means of amplifying its positive effectsvia a robotic interface (i.e., error augmentation of the patient’s reaching trajectory) has been extensively studied. However, even with utilizing suchneuro-rehabilitation paradigms, therapy robot...

Lexical choices in descriptions of the spatial world around us are affected not only by geometry, but also by variables such as situational context and the extent to which the spatial relations between the objects referred to are seen as consistent with their typical function. In a study of how people describe complex scenes with multiple objects we examined whether descriptive choices (both lo...

A satellite, in its orbit, is affected by perturbing forces, such as atmospheric drag, solar radiation pressure, Earth oblateness, and gravity of the celestial masses (other than the Earth). In this paper, the effects of these forces on the trajectories of different types of LEO satellites and a sample satellite (Z-SAT) are discussed. A few analyses are done on these orbits and the relevant res...

optimal balancing is a new approach based on optimal control a which modes, controls and the amount of equilibrium scale are calculated simultaneously. this approach has a significant effect on increasing performance of industrial robots which causes maximum decreasing of energy consumption. despite many applications of robotics such as welding and gluing, the path is predefined , but other unk...

In this paper we consider the output synchronization problem for heterogeneous networks of linear agents. The network’s communication infrastructure provides each agent with a linear combination of its own output relative to that of neighboring agents, and it allows the agents to exchange information about their own internal observer estimates. We design decentralized controllers based on setti...

Door passing is the basic capability of an intelligent wheelchair. This paper presents a novel strategy to address the door passing issue by dynamically generating the Bézier curve based trajectory. It consists of door finding, optimization based trajectory generation and tracking control, which are executed repeatedly to increase the ability of passing the door and improve the performance. Whe...

Driver expectation is about driver’s objective response and expectation for various traffic environments. It might directly influence the driving safety and traffic operation. This paper discusses in enough detail the shaping mechanism of driver expectation while considers road geometer parameters, driver behavior and vehicle performance in mountainous road. Combined various geometer parameters...
