Tetsuo Kinoshita "Basic Characteristics of a Macroscopic Measure for Detecting Abnormal Changes in a
Multiagent System," Sensors, Vol. 15, No. 4, pp.9112-9135, Apr. 2015, [IF: 2.033], [Times Cited: ]Abstract: Multiagent application systems must deal with various changes in both the system and the system
environment at runtime. Generally, such changes have undesirable negative effects on the system. To manage andcontrol the system, it is important to observe and detect negative effects using an appropriate observation functionof the system's behavior. This paper focuses on the design of this function and proposes a new macroscopic
measure with which to observe behavioral characteristics of a runtime multiagent system. The proposed measure
is designed as the variance of fluctuation of a macroscopic activity factor of the whole system, based ontheoretical analysis of the macroscopic behavioral model of a multiagent system. Experiments are conducted toinvestigate basic characteristics of the proposed measure, using a test bed system. The results of experiments showthat the proposed measure reacts quickly and increases drastically in response to abnormal changes in the system.
International impact on both academic and social aspects： This work provides a new macroscopic measure
for a multiagent system, which can detect undesirable changes in a multiagent system. This work attracts great
attention because it contributes to achieving a stable operation of a multiagent system by macroscopic
observation.

Engineering, Vol.27, No.10, pp.2700-2716, Oct. 2015, [IF: 2.476], [Times Cited: 8]

Abstract: This work provides an account of how data mining has been applied in managing networks and systems
for the past four decades, presumably since its birth. We look into the field's applications in the key Network andSystems Management (NSM) activities-discovery, monitoring, analysis, reporting, and domain knowledge
acquisition. In the end, we discuss our perspective on the issues that are considered critical for the effective
application of data mining in the modern systems which are characterized by heterogeneity and high dynamism.
International impact on both academic and social aspects： This work attracts rising attention because it gives
comprehensive discussions about data mining technologies and network and systems management, which is thekey technology to achieve future autonomic network and systems management.

Abstract: In this paper, we propose an algorithm for simultaneous indoor self-localization and Sound Source
Localization(SSL)

usingaswarmof

microphone-embedded-micro-quadrocopters(size10cm).

Micro-quadrocopters are extremely noisy, have low CPU power and cannot lift heavy equipment: the small
payload of each micro-quadrocopter only allows us to equip it with one microphone in addition to the inbuilt
motion sensors. To perform robust SSL despite these issues, we propose three functions: (1) Self-localization of
the quadrocopters using sound landmarks placed in the environment, and simultaneous localization of unknown
sound sources; (2) Sound source detection; (3) Distributed data fusion based on noisy information from all
members of the swarm. To achieve these, we propose three algorithms that are robust to noise, can perform with avarying number of quadrocopters, and do not rely on GPS nor motion capture to allow indoor operations: (1) Asound-based Unscented Kalman Filter (UKF) for self-localization of each quadrocopter; (2) A peak-basedalgorithm for sound source detection; (3) A distributed SSL algorithm for swarms with consensus-based
integration using a new filter termed Unscented Kalman Consensus Filter (UKCF). We evaluated the proposed
methods in real world and in simulated environments. The preliminary results show that the sound-based UKF
represents an improvement of 37% on position estimation precision compared to basic dead reckoning approaches,
even when the theoretical assumptions are violated; the distributed UKCF gives an improvement of 85% on SSL
compared to a single-sensor approach in simulation.
International impact on both academic and social aspects： This work contributes to indoor flying of drones
where positioning systems such as GPS cannot be used. It may give an impact on the development of indoor
applications utilizing autonomous drones such as emergency evacuation systems.

Abstract: When a disaster occurs, the demand for information and communication technology (ICT) services
drastically increases. To meet such demands, a national project was undertaken in Japan to develop the Movableand Deployable ICT Resource Unit (MDRU). One challenge regarding the MDRU is securing operators to work
the units in emergency situations. As ICT service users have diverse and frequently changing demands, strong
technical skills and practical knowledge are required for the administration of MDRUs. In this paper, we proposea knowledge-based network management system to alleviate the burden on administrators. To deal with thestructural changes to network systems that frequently occur with changes in ICT service demand, we introduce
modularization techniques into our previous research. The proposed system can be easily reconfigured by
join/disjoin modules corresponding to changes in the system configuration of the MDRU. The results of ourexperiments using the implemented experimental system confirm that the proposed system can be applied toMDRU operation and effectively supports administrators.
International impact on both academic and social aspects： The result of this work attracts great attention
because it is an essential and practical technique to realize automatic management of network systems in the
shortage of manpower such as disaster situation.

We have planned and organized the International Conference on Smart Technologies for Energy, Information andCommunication (IC-STEIC 2014) in Aug. 2014, which is a part of Bilateral Joint Research Projects between
Japan and Korea. Aim of STEIC2014 is to explore and discuss the present and future of the smart technologies
and their applications from a viewpoint of energy, information, and communication. Many researchers from Japanand Korea attended the conference and had deep discussions about smart technologies.

[2016-2018]
We have organized the First International Workshop on Practical Issues, Systems & Applications for Disaster Risk
Reduction in Smart Computing (DRRSC 2019) in Feb. 2019, which is also a part of Bilateral Joint Research
Projects between Japan and Korea. This workshop aims at practical research and study, new consumer electronics,
