Title: State of the art of Japanese Power Grid and Future Sustainable Green Energy Grid

     The earthquake and tsunami in the Kanto and Tohoku districts on 2011 greatly changed the energy situation in    Japan.  The center of energy in Japan until 2011 was nuclear energy. However, after 2011 the use of nuclear energy became difficult. As a result, Japan's energy self-sufficiency rate is 6%, which value is the world's lowest level.  Means to increase the energy self-sufficiency rate is the use of renewable energy such as solar power and wind power.  For this purpose, Japanese government plans to raise the use of renewable energy to 25% in 2030 and 50% in 2050.Therefore, the situation of the earthquake and tsunami in 2011, energy self-sufficiency rate in Japan and construction situation of smart grid are introduced in this paper. And this paper also introduces testing equipment of PCS and power storage system, which are key technologies to construct smart grid.  Also new power flow calculation method, which is able to calculate frequency, and concept of the future sustainable green energy grid are introduced in this paper. The new concept of energy grid is renewable energy power to hydrogen.

Title: Noise Robust Speech Recognition for AI-ROBOT

     This topic introduces the design of a noise robust speech recognition system. It is suitable for communication robots including an AI-ROBOT. For the valuable communication robots, a strong noisy robust speech recognition has been demanded. Although the dialog mechanism as human communications is one of interesting features into a robot, the command-based communications to a robot may be also important. When we consider the development of a command-based automatic speech recognition (ASR) system, we can design a strong robust ASR against various noise circumstances.
In this presentation, new advanced speech analysis techniques named time varying speech features have been introduced. In order to develop the robustness under low SNR, Dynamic Range Adjustment (DRA) and Modulation Spectrum Control (MSC) have been proposed for the obtained time-varying speech features and they focus on the speech feature adjustment with an important speech components. DRA normalizes dynamic ranges and MSC eliminates the noise corruption of speech feature parameters.
Even if these proposed algorithms are applied to noisy speech, it is difficult to recognize several similar pronunciation phrases. Discrimination of similar pronunciation phrases is more difficult than that of normal phrases under low SNR circumstances. In this topic, we introduce the use of fast Fourier transform (FFT) based mel-frequency cepstral coefficients (MFCC) and time-varying linear predictive coding (tvLPC) based MFCC. Due to the presence of intra-frame variations in tvLPC, it is expected that this approach can improve speech recognition. Evaluation results demonstrate that the proposed approach achieves better speech recognition performance at low SNR conditions.

Title: Intelligent Robot as a Cyber Physical System in Society5.0

     IoT technologies including the concepts of CPS (Cyber Physical System), Industry4.0, Industrial Internet, Connected Industries, and Society5.0 are indispensable for designing and building future social intelligent robot systems. Human-Robot interaction, Safety mechanism and control, and Soft robotics are also important technologies. Human-Symbiotic Robot is a typical application of those technologies.
In this speech, first, I introduce Society 5.0 and its concept proposed by Japanese government. And I show several approaches to realize intelligent Human-Symbiotic Robots based on that concepts. In designing those systems, computational intelligence and mechanical design are important two key technologies. In the process of integrating both technologies, the advantages and disadvantages of those technologies should be considered. Computational intelligence realizes universal adaptability, and special mechanical design realizes ideal specifications and low cost. Both approaches should be merged together to realize intelligent systems such as Human-Symbiotic robots. I call its approach "Embodiment Informatics". I will introduce several research topics in Embodiment Informatics.

Title: Differential-Phase-Shift Quantum Key Distribution

     Unlike classical cryptography, whose security relies on unproven mathematical assumptions, quantum key distribution (QKD) can information-theoretically distribute secret key bits between distant parties. According to quantum mechanics, any eavesdropping on a quantum channel will be disclosed.

Differential-phase-shift (DPS) is an important QKD protocol, since it can be implemented with very high repetition rate. More importantly, round-robin-differential-phase-shift (RRDPS) protocol, which is a variant of DPS protocol, has several notable advantages over other protocols. The main merit is that signal disturbance monitoring can be removed during the RRDPS protocol. The removal of monitoring is quite meaningful in practice.

We obtain an improved theoretical bound on the information leakage. Consequently, we verify our theory through a proof-of-principle experiment, which can run at a distance of 30 km without signal disturbance monitoring and decoy states. In addition, a demonstration at 140 km is also realized with monitoring signal disturbance and decoy states.

Title: Smart Grids: Research consideration and current skills for new jobs
DC micro grid,
Currently, there is a drop in the price of distributed energy resources, especially solar PV, which leads to a significant growth of their installed capacity in many countries. On the other hand, Energy efficiency and renewable energy entail multiple benefits beyond energy savings and CO2 emission reductions. In recent years, EU countries have many policies to promote energy efficiency and renewable energy through the concept of AC smart grid. 
Development of DC loads in domestic such as LED lighting, computers, telephones, televisions, efficient DC motors and electric vehicles leads to rethink the strategy of energy distribution. Corresponding to this change, DC microgrid distribution system becomes more attractive than the traditional AC distribution system. The main advantages of DC microgrid are higher energy efficiency, easier in integrating with distributed energy sources and storage system.
While many studies concentrate AC smart grids and energy management, our work has focus on DC microgrid and the corresponding DC protection because it still receives inadequate attention and lack of regulations and experiences. Protection in DC grid is more complex than AC grid due to the continuous arc, higher short circuit current value and fault rate of rising.

New skills for new jobs,
Energy efficiency objective is currently an EU regulation and it has forced our education curricula to adapt the classical knowledge learning in our electrical degree’s to fit the industrial needs.
