The insulation of stator winding in a rotating machine consisted of mica and epoxy resin materials. The structure was also composed of junctions, so, a diagnostic monitoring condition of this insulation was taken into consideration. First, the results of the polarisation and depolarisation current measurement (PDC) of the test sample (stator winding rate of 13.8 kV) were investigated, as an experiment in the laboratory. The conditions of the experiment were conducted under different thermal stresses of 25°C and 100°C. The test sample was full stator bar. As found, the trend of the temperature of the winding rise if the current of the polarisation and depolarisation was increased. Second, the results of the PDC were calculated from the time domain to the frequency domain. The aim found that the aging point of the insulation system should take into consideration the results of the calculation of the frequency domain. The aging of the insulation system was a variant by the thermal stress, which was an effect from the complex capacitance and polarisation losses in the insulation winding system. Finally, this identified the phenomenon of the aging of the machine insulation system.

Tsunami is known as one of the most destructive natural disasters. Aiming to measure Tsunami, our laboratory proposed a method based on binocular stereo vision. As we calculate the 3D coordinates of sea waves, the sea surface height in surveillance area can be measured in real time. Sea wave extraction and sea wave matching are two key steps in the above method. By conventional image processing methods, the effects of sea wave extraction and sea wave matching are not satisfactory because of uneven illuminance and different filming angles. In this paper, we propose a method of sea wave extraction and sea wave matching based on Convolutional Neural Network (CNN). Firstly, we take photos of the sea surface with two cameras. Given the raw photos, we divide them into small blocks of waves. According to the wave quantity in each block, we can build databases for sea wave extraction. And databases for sea wave matching can be built according to the matching situation of two blocks from left and right photos. Then we make use of the open-source software library Tensorflow to establish two CNN frameworks. After being trained by training databases, experiments on the test database show that the two CNN systems can separately extract and match sea waves from photos with considerable accuracy within several seconds. Besides, our network is self-adaptive to different sea wave images as well as to different camera settings.

Databases and big data integration are keywords which attract attentions from both government and private sectors' administrators. In general, the term big data refers to data of large volume which come in different varieties and high velocity. Typical big data sources are from sensors of various kinds and social media. Transactional data from enterprise information systems with traditional structured databases are also major data sources for management decision support systems. This paper presents some key big data and database integration issues and suggests the level of integration required.

Digital terrestrial television (DTTV) propagation loss should be known characteristics of DTTV propagation channels. In Thailand used DVB-T2 standard for broadcast television channel which shell be study. DTTV propagation loss based in measurement data with system design and analysis of DTTV parameters are importance. In order to predict the result of the broadcast of DVB-T2 in Pathumthani, Thailand, the Hata propagation model is used as the calibration and optimization method for the measurement results. The measurement of the DVB-T2 signal which broadcast from transmitted station are collect as the source of research data. Two broadcast channels were sampling as the broadcasting frequency in this research, i.e., 626 MHz (CH40) and 658 MHz (CH44). The separated distance between transmitted station and received antenna were in range of 2 km. to 7 km. The least square method is use as the optimized propagation model of DVB-T2 signal. The mean error and root mean square error are use as the statistical value for the calibrated model, while relative error is use to indicate the comparison of model component. In the DTTV propagation channel analysis, the root means square error and the optimized method of calibrated model has relative error higher than the calibrated model with mean error. From the results, it shows that the calibrated model of Hata propagation model with mean error is suitable for predict DTTV propagation loss in urban area of Thailand.

Nowadays, people tend to increasingly have more stress because of the bad economy, high living expenses, etc. Listening to music is a key activity that assists to reduce stress. However, it may be unhelpful if the music does not suit the current emotion of the listener. Moreover, there is no music player which is able to select songs based on the user emotion. To solve this problem, this paper proposes an emotion-based music player, which is able to suggest songs based on the user's emotions; sad, happy, neutral and angry. The application receives either the user's heart rate or facial image from a smart band or mobile camera. It then uses the classification method to identify the user's emotion. This paper presents 2 kinds of the classification method; the heart rate-based and the facial image-based methods. Then, the application returns songs which have the same mood as the user's emotion. The experimental results show that the proposed approach is able to precisely classify the happy emotion because the heart rate range of this emotion is wide.
