The purpose of this study is to realize a practical method of providing cyber security for power system communications. Considering communication requirements needed for Smart Grids, power system communications can be classified into five main categories: real-time protection, supervisory control and data acquisition (SCADA), remote access, demand management system (DMS) and advanced metering infrastructure...
Most Thai text-to-speech systems on personal computers can synthesize sound in real time with acceptable quality. However, when porting the Thai TTS systems to limited-resource systems such as mobile devices, computational time has to be reduced. Hence, the quality of synthesized sound is decreased. Even though Flite_Thai, a unit concatenation synthesizer for Thai, can reduce the computational time...
Using 6.3 fs pulse laser, both spectral change in the electronic absorption spectrum and instantaneous vibrational frequency could be observed by real-time vibrational spectroscopy. Ultrafast geometrical relaxation taking place in 60-100 fs could be clarified.
The purpose of this study is to produce practical cyber security for protection relay systems using communication channels, such as pilot protection schemes or wide area protection systems. This paper describes a concept and method of effectively applying unconditionally secure authentication codes (A-codes) to such protection relay systems. From the requirements of real-time communication and long-term...
We developed software that automatically detects unusual motions in a video sequence in real-time by using an efficient implementation of CHLAC and a visual software framework called Lavatube. Video monitoring systems that can automatically detect unusual motions are currently in great demand. CHLAC has been shown to work effectively and favorably for this task. A newly developed parallel processing...
When it comes to the real-time optimization of nonlinear control systems, model predictive control (MPC) and state-dependent Riccati equation (SDRE) methods are known to be effective and reliable. In this paper, we propose a new type of real-time control method for constrained nonlinear systems and demonstrate by some numerical simulations that the proposed method is also effective and reliable. In...
