Gestural and facial communication with smart phone based robot partner using emotional model

János Botzheim Jinseok Woo Noel Tay Nuo Wi Toru Yamaguchi Naoyuki Kubota

Publication Name: World Automation Congress Proceedings

Publication Date: 2014-10-24

Volume: Unknown

Issue: Unknown

Page Range: 644-649

Description:

When conducting natural communication in addition to perform verbal communication, a robot partner should also understand non-verbal communication such as facial and gestural information. The word 'understand' for the robot means how to grasp the meaning of the gesture itself. In this paper we propose a smart phone based system, where an emotional model connects the facial and gestural communication of a human and a robot partner. The input of the emotional model is based on face classification and gesture recognition from the human side. Based on the emotional model, the output action such as gestural and facial expressions for the robot is calculated.

Time optimal control of ground vehicles

Publication Name: Sisy 2014 IEEE 12th International Symposium on Intelligent Systems and Informatics Proceedings

Publication Date: 2014-10-14

Volume: Unknown

Issue: Unknown

Page Range: 245-250

Description:

The paper deals with the time optimal control of automatically driven cars modeled with gear shift as discrete control input beside the continuous ones in a test path between corridors. The car is required to avoid a static obstacle or performing double lane change. The problem can be formulated as a mixed-integer optimal control problem (MIOCP). The resulting MIOCP is solved by reformulating it to static mixed-integer nonlinear program (MINLP) using time discretization and direct multiple shooting method. Non-commercial open software packages are applied that substantially use the gradients of the objective function and the Jacobians of the constraints exploiting sparsity. A novel algorithm and implementation is presented for computing the derivatives of the complex state trajectory joining equations. This algorithm was given in the form of matrix differential equations whose structure allowed to compute their solution using RK4 in matrix form. The elaborated method can be applied both for combustion engine and electric driven cars. It can form the basis to generate an offline database of a central general collision avoidance system (CAS) for varying path parameters on a grid which can support real time applications.

A control strategy to minimize magnet losses in vehicle PMSM by field-weakening operation

I. Szenasy Zoltán Szeli Z. Varga Péter Kőrös

Publication Name: 2013 World Electric Vehicle Symposium and Exhibition Evs 2014

Description:

An applied control of PMSM is the flux weakening operation for extending the region over nominal speed on nominal voltage. This paper deals with these questions and its impacts. The proved method increases the torque angle and with this the d axis directed component of the stator current vector for reduce the main flux, but the loss developing in magnets became significant. These impacts and its reduction need several investigations. Our work indicates the possibilities and limits of flux-weakening for a given PMSM, and a usable control strategy.

Trust-based knowledge management system building

Bencsik Andrea Irma Rácz

Publication Name: Knowledge Management for Competitive Advantage During Economic Crisis

Publication Date: 2014-09-30

Volume: Unknown

Issue: Unknown

Page Range: 16-37

Description:

This chapter introduces the importance of trust in knowledge management system building. It argues that the relationships among organizational culture, problems of knowledge sharing, and HR features are in close correlation with each other. The main aspect of the chapter is to show the general requirements and pre-requisites of knowledge management system building based on trust. The authors aim to reveal the theoretical aspect of trust-based culture and knowledge management system building, and the HR's tasks connected to these two ideas. The chapter presents three case studies on three different companies' practices, a multinational, big company, and an institution. This chapter shows samples, best practices, critical steps that can ensure success to the companies that want to start building a knowledge management system.

An overview of research trends in CogInfoCom

Page Range: 181-186

Description:

Cognitive infocommunications (CogInfoCom) is an interdisciplinary field that targets engineering applications based on emergent synergies between ICT and the cognitive sciences. The unique perspective of CogInfoCom enables researchers to focus on both the qualitative and quantitative analysis of cognitive capabilities in application areas where humans are becoming increasingly entangled with and dependent on intelligent networked services. An international conference on the field has been held every year since 2010, and the two most recent events have been supported by the IEEE. In this paper, we provide an overview of the various research directions which have been represented at the conference series, and which have as a result gained strong relevance to CogInfoCom during the past few years.

Publication Name: Ines 2014 IEEE 18th International Conference on Intelligent Engineering Systems Proceedings

Publication Date: 2014-09-24

Volume: Unknown

Issue: Unknown

Page Range: 203-207

Description:

The paper summarizes our ideas and solutions in the subject of developing a rapid prototype-capable robot platform. Constructing a robotic platform for scientific researches means to find a robust electrical and mechanical system which is connected to a high computational device and it is easily programmable. Usually the first two features can be funded in industrial robots which unfortunately do not possess the last two. The presented solution refers to a mobile robot (Neobotix MP500) tuned with an extra computer and programmed with LabVIEW.
