Plenary Talks

The possible future revision of the International System of Units, the SI

Dr. Estefanía de Mirandés

Dr. Estefanía de Mirandés and Dr. Alain Picard

Bureau International des Poids et Mesures, France

Abstract:

The International Bureau of Weights and Measures (BIPM) and National Metrology Institutes (NMIs) have spent many years advancing and improving the International System of Units (SI) by extending the frontiers of metrology to allow a definition of the SI base units in terms of invariants of nature - the fundamental physical constants h, e, k and NA for the definition of the kilogram, ampere, kelvin and mole, respectively.

The numerical values of the fundamental constants h, e, k and NA and their associated uncertainties will be established by CODATA using a sophisticated method to minimize the uncertainty of these values while ensuring consistency among the recommended values for all physical constants.

If the results of experiments are satisfactory and the needs of users are met, formal proposals for changes in the definitions of the kilogram, ampere, kelvin and mole can be presented to a future General Conference on Weights and Measures (CGPM).

The lecture will present the possible future revision of the SI, the current status of determination of the Planck, Avogadro and Boltzmann constants, the criteria for acceptance of the new definitions and the consequences for users when the ‘New SI’ is adopted at a future meeting of the CGPM.

CONTROL AND OPTIMIZATION IN CYBERPHYSICAL SYSTEMS:
FROM SENSOR NETWORKS TO “SMART PARKING” APPS

Dr. Christos G. Cassandras

Boston University, USA

Abstract:

Sensor networks are multi-agent systems consisting of distributed nodes that cooperate to meet a common objective, often in an uncertain environment. Viewed as a cyberphysical control system, a sensor network encompasses three interconnected functionalities: coverage, data source detection, and data collection. We will describe an optimization framework for controlling the location and movement of nodes so as to combine these functionalities. We also address the issue of information exchange among nodes aiming to minimize inter-node communication. We show that event-driven, rather than synchronous, communication can guarantee convergence to optimal solutions while drastically reducing the need for inter-node communication, thus also reducing energy consumption and extending the network's lifetime.

Despite significant advances, these systems remain largely used for data collection from physical sources. There has been limited progress on the processing of data to drive actuation and form a complete closed-loop cyberphysical control system. We describe one such system recently developed for dynamic resource allocation in an urban environment. Termed a “smart parking” system, it dynamically assigns and reserves an optimal resource (parking space) for a user (driver) based on an objective function that combines proximity to destination and parking cost, while also ensuring that the overall parking capacity is efficiently utilized. When an optimal allocation is updated, it is guaranteed to avoid reservation conflicts and to preserve a monotonically nonincreasing cost for every user relative to current assignment. We will describe an implementation of this system at a Boston University parking facility based on driver requests entered through a smartphone app.

University of Tokyo, Japan

Abstract:

The Great Eastern Japan Earthquake and Tsunami occurred in March 11, 2011, and the accident of Fukushima Daiichi Nuclear Power Plant occurred due to the earthquake and the tsunami. There have been lots of needs of remote-controlled machine technology including robot technology (RT) for the response of the disaster and the accident. Especially, in the case of accident of the nuclear power plant, various tasks are required to accomplish in the high-radiation environment, and utilization of remote-controlled machine technology was essential. In this presentation, it is introduced how the technology has been introduced and utilized in the emergent situation of the disaster, and what kind of technology is still demanded for the middle-range and long-range missions towards decommission of the nuclear power plants. It is also analyzed why the robot technology developed in the projects in Japan so far could not be introduced smoothly in the emergent situation, and issues are discussed how we should prepare for the disasters and accidents that can occur in future, including not only practical technology development but also maintenance of technology, training of operators, their system and organization such as mockups and test fields, and political strategy to realize it.

Robust 3-D Vision Techniques: Algorithms and Applications

Dr. In So Kweon

Dr. In So Kweon

KAIST, KOREA

Abstract:

For the 3D reconstruction of static and dynamic scenes, we have developed several robust computer vision methods ranging from the image enhancement to the design of novel camera systems. In this talk, we first present a sparse-model based approach to recover the camera response function, which is crucial for many color image processing problems such as high dynamic range imaging and photo-consistent mosaicking. We also present a sensor-fusion based approach to obtain super-resolution (SR) depth images from low-resolution depth images and high-resolution color images. A learning-based optimization framework successfully recovers the SR depth images. The second part of the talk introduces new camera systems to capture the 3D information accurately and efficiently. The camera systems include (i) “camera + depth” fusion camera systems, (ii) a fast bundle adjustment based approach for large-scale datasets, (iii) a novel coded-light photometric stereo for modeling 3-D dynamic scenes. Specifically, we present a hand-held fusion sensor system, consisting of four cameras and two 2D laser scanners, to capture 3D information of large-scale scenes. This new approach allows boosting the advantages of two sensor systems and complements the weakness of the two. As an important application of 3D vision techniques, we demonstrate the robustness of the methods by automatically reconstructing a large-scale environment, such as KAIST campus.
