The purposes of this study were to investigate the component of information and communication technology (ICT) competency for Thai e-commerce personnel and presents The model of competency development in ICT for Thai e-Commerce personnel. The questionnaire was administered to collect quantitative data from 385 electronic business personnel samples and the in-depth interview method was applied to obtain qualitative data from 10 experts in information and communication technology from public and private sectors. The collected data were analyzed by frequency distribution percentage distribution mean standard deviation and Exploratory Factor Analysis (EFA). The results revealed three components with 47 variables of ICT competency for Thai for Thai e-commerce personnel which can describe the combined variance at 74.979 percent. Of all variables 36 variables are highly necessary to identify the competency to design and develop websites and benefit the ability to develop and improve the website according DBD Verified. Six variables refer to the competency concerning the interpersonal skill and responsibility among the personnel inside or outside the organization. Finally five other variables are responsible for the ability to carefully analyze troubles with caution.

This thesis offers the design of the impulse generator 1.2 / 50 μs which applies for studying and generating the lightning impulse to test the endurance of the electricity transmission line. Moreover this study analyses the factors which affects the impulse waveform by using Orcad program. The parts of prototype device can find in the general market. After the efficiency test of the electricity transmission line the result shown that the device should have the high capability to endure the temporarily high impulse. This minimizes the dangerous from the electricity system.

Particle swarm optimization based NBTI modeling for finFET circuits
Particle swarm optimization based NBTI modeling for finFET circuits

Fin Field Effect Transistor (FinFET) technology has increasingly been adopted for use within integrated circuits thanks to its superior electrical integrity and scalability. However a steady increase in vulnerability of FinFET circuits to negative bias temperature instability (NBTI) has recently become one of the major lifetime reliability problems. In this paper we propose a simulation framework to address NBTI in combinational circuits implemented with 14-nm tri-gate FinFET predictive technology. Particle swarm optimization (PSO) algorithm is applied to construct an accurate long-term NBTI degradation model from cycle-by-cycle data history. The proposed simulation methodology provides accurate results with high efficacy in computation time compared to reference models. From the proposed framework the average delay degradation for all experimental circuits under normal operation after 10-year NBTI stress is approximately 6% yet temperature variation in the circuit strongly influences NBTI degradation.

In this paper proposed remote sensing using Normalized Difference Vegetation Index from NOAA STAR cluster value from k-means temperature rainfall number of rainy days and runoff to create runoff prediction model using Artificial Neural Network (ANN) and evaluated runoff models with the R2 and RMSE. The results show that the using of cluster value with other parameters to create predictive models can enhance forecasting results. When using Normalized Difference Vegetation Index with temperature value at lag time 1-2 month and cluster value at lag time 1 month to create model with ANN we have got the best performance which are RMSE=0.09 and R2=0.743. The experimental results shows that remote sensing data and cluster value from k-means can be used to predictive the runoff effectively.
