Dengue fever is a tropical disease caused by dengue virus. This virus is transmitted by mosquitoes. Dengue can also be transmitted via infected blood products and through organ donation. There are many infected people in each year. Thus, if the number of patients can be predicted, vaccines for dengue fever will be able to prepare for serving all patients in that area. This research proposed a two-step prediction method that combines time series forecasting analysis and supervised learning techniques to predict the number of dengue fever patient cases. In generally, the result of prediction from only the number of patient cases is not good enough for application; accuracy and confidence are low. In this research, the environmental factors are considered and predicted. Then, these factors are used for predicting the number patient cases. The experimental results show that the proposed two-step prediction technique is a good choice for dengue fever prediction. The accuracy is better than the simple prediction technique.

The quality of a finished MESFET is assessed by evaluating its DC and AC characteristics, whilst the target characteristics can be achieved by optimizing the device parameters prior to its fabrication. In this research the I - V and R.F characteristics of submicron SiC MESFET are simulated. In order to achieve optimum values of simulated intrinsic parameters, an objective function based on experimental data for both phase and magnitude is defined. The device intrinsic small signal parameters are then evaluated by using the simulated data. By using particle swarm optimization, different gains of the device and insertion loss are also taken into account which helped in formulating a good agreement between simulated and experimental data.

The objective of this study is to compare Bayesian models and Bayesian maps under several different heterogeneity variance priors after controlling with the same data and the same mean prior in the application of standardized morbidity ratio (SMR) of HIV/AIDS infection in Thailand 2013. Three noniterative estimators of heterogeneity variance priors for SMRs as dispersion measures among areas are compared to produce the best fitting model and map. The data source of the number of newly diagnosed HIV/ AIDS cases infected out of the persons who come to receive medical treatments including blood test is provided by the National AIDS Program (NAP), collected by the National Health Security Office (NHSO). The results showed that the first heterogeneity variance prior estimate derived from the marginal variance estimator of observed number of HIV/AIDS cases performs best with the smallest deviance information criterion (DIC), the largest log-marginal-likelihood, and the highest posterior probability, leading to a suitable map with five high risk classes of SMR classification under Bayesian mapping. Practically, the prior information on the mean is the most popular use to improve Bayes estimates; however, a recommendation based upon an acceptable prior on the heterogeneity variance after controlling the same mean prior from this study result is also adopted as an alternative choice.

A technique has been proposed for a more accurate estimation and compensation of mutual coupling in transmitting antenna array system. The compensation consists of the modification in feed voltage based upon the value of the mutual impedance found using FEKO. Pattern multiplication technique has been used to obtain the coupling-free azimuthal gain pattern with specific feed voltage. With the same feed voltage the pattern has been obtained in FEKO to observe the effect of mutual coupling. Finally, the coupled gain pattern has been obtained with the compensated feed voltage. All the three radiation patterns have been compared to see the effect of the coupling as well as the effectiveness of the compensation technique.

This paper proposes the series connected bidirectional soft switching resonant converter (BSRC). The BSRC is composed of 4 switches to increase the DC bus voltage for transferring the energy of PV and energy storage. The modes of operation divide in two modes for operating bidirectional voltages. The first part is the boost mode which is controlled for the constant 48 volts from batteries $(mathbf{V}_{mathbf{B}mathbf{a}mathbf{t}mathbf{t}pmb{1,2}})$ to the DC voltage buses $(mathbf{V}_{mathbf{H}mathbf{i}mathbf{g}mathbf{h}})$ and second is buck mode at 24 volts for charging the batteries. The asymmetrical duty cycle control techniques (ADC) is proposed to control the constant input voltage for charging battery and DC voltage buses. The simulation and experimental results were given to verify the operation principles of the proposed BSRC and to evaluate its power regulation.

Electric power demand prediction is an important task for the efficient, economic, reliable and accurate power system operations which can be unit commitment, maintenance scheduling, etc. Considering importance of load forecasting different models are proposed for power demand forecasting. ANN is the most widely used method for power demand forecast from years. Simulation results obtained show that ANN is capable of forecasting electricity loads effectively. In this paper different ANN has been applied in short-term demand forecasting that is, the one hour-ahead hourly forecast of the electricity power demand using MATLAB R14a. The simulation results have shown highly accurate one hour ahead load forecast.

Battery monitoring system for dc distribution applying in a substation is presented in this paper. Both MEA and PEA substation uses lead acid type batteries for a de distribution using as a backup source. Therefore, a battery monitoring is a key function in a charger to check battery condition; however, a traditional charger used in a substation does not have this function. A lead acid battery first order equivalent circuit is utilized to analyze the battery condition by probing an internal resistance of a battery. A first order equivalent circuit is used to determined battery parameters using transient response analysis. PSIM is also used to simulate the proposed equivalent circuit properties comparing to experimental result. The experimental results are conducted by using three lead acid batteries which are used in a PEA substation. The travelling wave theory is also applied to determine the health of under tested batteries. Both simulation and experimental results show that the proposed technique is promising technique to implement in a charger function for detecting a battery condition as a proactive maintenance.
