High-speed trains in Thailand use AC traction system with 2×25 kV and 50 Hz power system. In traction system, it consists of power electronic devices; therefore, trains can be considered as moveable sources of harmonics in power system. For supplying electrical power to trains, three-phase high voltage (HV) to two-phase medium voltage (MV) by special transformers has been used. This paper focuses on developing 2×25 kV highspeed railway (HSR) system consisting of catenary system, highspeed rail loads and various kinds of specially connected transformer models. Three types of specially connected transformers, i.e. V-V transformer, Scott transformer and Modified Woodbridge transformer, are modeled and verified by DIgSILENT PowerFactory software. The impacts on voltage distortion from HSR system connected to utility grid at point-of-common coupling (PCC) with different types of special transformers are analyzed and compared. It is found that harmonics currents can have different impacts on utility grid by different specially connected transformers. Selecting an appropriate range of short-circuit power from an early stage of construction of high-speed railway until future expansion of high-speed rail loads is crucial to evaluate the total life cycle cost of the developed HSR project.

In this paper a new cascaded multi level inverter is proposed. It consists of a basic module which can generate fifteen level output considering zero level. PWM switching scheme is used here for generating the pulses for the switches in the proposed topology. This topology shows the advantages over some of existing topology reported in the literature in respect of number of switches, drivers, sources etc. It can also be applied for symmetric as well as asymmetric configuration. Validation of the proposed topology has been ascertained by simulation in Matlab environment and hardware set up has been developed for fifteen level multi level inverter. Hardware and simulation results are in close agreement with each other.

The paper deals with the stability analysis of DC micro-grid system (DC MGs). The eigenvalue theorem is applied with the proposed model derived from the DQ method and the generalize state-space averaging (GSSA) method. It can be found from the stability study that the irradiance of PV arrays can significantly affect to the stability margin of DC MGs. The simulation results via the exact topological model of MATLAB are used to confirm the theoretical results. A good agreement between the simulation and theory can be achieved. Moreover, the effect of irradiance changing on stability issue is very important. This effect has to be considered for DC MGs to avoid the unstable operation.

The electronic based system and health information technology were used and integrated in healthcare service because the electronic systems provide better quality, efficiency, and outcome of healthcare service. By improving the quality of care, the electronic system was to adapt and adopt into the healthcare service including the nursing service of long term care. In Home Health Care unit, Ramathibodi hospital, it was 2 systems in this service, the paper based and electronic based systems. Surveying the existing system found that the electronic based was supported only one process, which is the consulting process, but other processes mostly had to record in paper based. This paper developed the electronic record system applied into their services. Also, before implementing the new system into the working process, the comparing effectiveness and efficiency between existing as paper based and the new system as electronic based were defined. There were aspects of the number of incidents of data error, incompleteness, inconsistency and different time between using both systems to record.

A novel image analysis method for identifying nutrient deficiencies in plant based on its leaf is proposed. First, the proposed method divides an input leaf image into small blocks. Second, each block of leaf pixels is fed to a set of convolutional neural networks (CNNs). Each CNN is specifically trained for a nutrient deficiency and is utilized to decide if a block is presenting any symptom of the corresponding nutrient deficiency. Next, the responses from all CNNs are integrated to produce a single response for the block using a winner-take-all strategy. Finally, the responses from all blocks are integrated into one using a multi-layer perceptron to produce a final response for the whole leaf. Validation of the proposed method was performed on a set of black gram (Vigna mungo) plants grown under nutrient-controlled environments. Five types of deficiencies, i.e., Ca, Fe, K, Mg, and N deficiencies, and a group of plants with complete nutrients were studied. A dataset consisting of 3,000 leaf images was collected and used for experimentation. Experimental results indicate the superiority of the proposed method over trained humans in nutrient deficiency identification.

Preliminary study of psychological stress on physiological parameters has been reported. Six healthy college students (male=3, female=3) participated in the modified Trier Social Stress Test (TSST). Their Electrocardiogram (ECG), Photoplethysmogram (PPG) were monitored in 5-stage experiment. Two Pulse Transit Time (PTT) were generated within each cardiac cycle from the period of R-wave presented in ECG to (1) the peak (systolic pressure) in PPG; “PTT+” and (2) the valley (diastolic pressure) in PPG; “PTT-”. The mean and standard deviation of these two PTTs were reported across the stages. More data will be recruited for statistical comparison in the future.

Currently, wireless sensor network has important in the role of the short-range wireless communication, especially in, an indoor localization. However, there are more factors of the indoor environment caused to reduce the precise localization and also increase the error of distance. This paper presents a new method to evaluate the wireless sensor network (WSN) technology for the indoor localization. The proposed methods are using received signal strength indicator (RSSI) to compute the error of distance based on weighting algorithms. Whereby the weight range localizer (WRL) and relative span exponential weight range localizer (RS-WRL) is proposed in this paper. As the results, the cumulative distribution function (CDF) probability indicates the error of distance as properly, and this method can help to increase the precision of range based localization method in an application of indoor environment.

This paper presents an optimal zero-sequence selection based on two-phase space vector pulse width modulation for five-leg inverter fed dual two-phase induction motors. The proposed zero-sequence selection of common b is determined which can reduce the peaks of resultant duty cycle before overmodulation resulting in an extension of a linear range of modulation index. As a result, the proposed strategy offers better DC-bus utilization when compared to a conventional strategy for a five-leg voltage source inverter.
