Abstract:

Robotics was initially and for a long time guided by needs in industry. Indeed, the early years of robotics was largely focused on robot manipulators, used mainly for simple and repetitive automation tasks. The first industrial robot manipulator appeared in 1961 in the assembly lines of General Motors.The early control systems for robot manipulators were designed to control independently each axis of the robot as a Single-Input-Single-Output (SISO) linear system. Linear automatic control theory was then extensively used in this basic solution, where the coupling dynamics between the different axes of the robot were often neglected and the robot model significantly simplified. Beyond these issues, the main barriers to progress were the high cost of computation, the lack of good sensors, and the lack of fundamental understanding of robot dynamics. However, the progress of robotics and automation as well as their associated innovative applications has required the consideration of more and more complex tasks needing high performances. These challenging tasks required a deeply understanding of complex nonlinear dynamics of robots. Besides, it has also motivated the development of new theoretical advances in different control fields (robust, adaptive, etc.), which has consequently enabled more sophisticated applications. Nowadays, robotic control systems are highly advanced, including manipulation robotics,underactuated robotics, underwater robotics, aerial robotics, mobile robotics, medical robotics, parallel robotics, wearable robotics, humanoid robotics and more others.

In this lecture the main challenges related to control of robotic systems will be emphasized, and illustrated through different fields in robotics. For each of these fields, the motivations and the need of developing sophisticated control schemes will be first highlighted. Then some proposed control solutions will be illustrated through real-time experiments on different platforms. The experimental results are used to show the efficiency and robustness of the proposed control schemes.

Abstract:

Blind signal separation is an emerging field of research with a broad range of applications. It is motivated by practical problems that involve several source signals and several sensors. Each sensor receives a mixture of the source signals. The problem under consideration consists of recovering the original waveforms of the source signals without any knowledge of the mixture structure. The latter may be instantaneous linear mixture, convolutive mixture or nonlinear mixture. This talk concentrates on the instantaneous linear model, which corresponds to a linear memoryless channel. This model has shown to be a good approximation in various applications such as  jammer mitigation, eye artifact removal in electroencephalography, rotating machine monitoring, airport surveillance, financial time series analysis and telecommunications.

The talk is an introduction to the blind signal separation problem.  An attempt of classification of the existing methods will be provided. Some applications will be presented together with  new challenges  in the field.

The speaker plans to address a broad audience with general background in signal processing.

Abstract:

Recent advances in technology and manufacturing have made it possible to create small, versatile, energy-efficient, cost-effective sensor nodes for specialized applications. These nodes can be made “smart” enough to be capable of self-awareness, adaptation, and self-organization. Thus, when networked, they lend themselves to be the back bone for the next generation, 5th generation, wireless communication networks (G5) as well as the emerging internet of things (IoT).

Sensor and cellular networks for sustainable development cover relevant technologies that increase the quality of human life and encourage societal progress with minimal effect on the earth’s natural resources and environment. The plenary session will be organized as a collection of subjects that capture the current state of the art and explore applications where sensor and cellular networks are used for sustainable development in agriculture, environment, energy, healthcare, transportation, disaster management, and safety and security. These applications are often made possible using supporting technologies such as unmanned aerial vehicles, massive multi-input multi-output systems (massive MIMOs), as well as other technologies such as visible light communication (VLC).

The session will be beneficial to designers and planners of emerging sensor and cellular telecommunication networks, researchers in related industries, and students and academics seeking to learn about the impact of sensor and cellular networks on sustainable development. Specifically, the session will provide technical information about smart sensor and cellular networks and their use in everything from remote patient monitoring through body-wide networks to crop monitoring and smart farming.
