The image enhancement process of a digital image is a part of digital signal processing which it plays an important role in some industrial segments for instance object classification or bio-identification satellite exploration or aerial images robot vision cancer treatment etc. These image applications are necessary to consume many resources in physical hardware and computer programming including the intelligent algorithm development of complexly advanced processing in order to enhance digital images – as well as be easy to analyse by humans. This research is aimed to present on Contrast Enhancement using Bi-Histogram Equalization via Two Dimensional Discrete Wavelet Transform (BHE2DWT) in order to compose the coefficient wavelet from other signals. At the end of the process information on the approximation band from DWT will be divided into two sub-histograms and then histograms will be independently equalized. After that resulting histograms will be decomposed by IDWT. Resulting images will be not only more displaying in high contrast than their original images but also preserve the absolute mean brightness error (AMBE) to close their original images.

The purposes of the research was to develop the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon including found out the quality by the experts and the system users’ satisfaction. The research tools were as follows: 1) the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon 2) quality evaluation form and 3) a questionnaire on users’ satisfaction. Tool for system development of this research were Microsoft FrontPage and Macromedia Flash Version 8.0. The research sampling group consisted of 30 the administers and staffs educational from assurance departments. The results of this research was found that the quality evaluated by experts in content towards the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was as a good level the average mean was as 4.15 and the standard deviation was as 0.63 in order words. The quality evaluated by experts in multimedia was 4.16 on the average or at a good level and the standard deviation was as 0.41 in order words. The users’ satisfaction on the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was 3.97 on the average or at a good level and the standard deviation was as 0.06. Therefore the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was able to be used properly.

The objectives of this research are to estimate the morbidity rates of Hypertension and Ischemic heart disease in each province of Thailand to investigate factors influencing on the morbidity rates and to construct the disease maps of those two diseases. The generalized linear mixed model (GLMM) in which the responses have a Poisson distribution and the spatial effects are a multivariate conditional autoregressive model (MCAR) are adopted. The provincial secondary data sets consisting of a number of Hypertension and Ischemic heart disease patients an average income per head and a student proportion were collected. The results show the average income per head (Relative Risk (RR) = 1.0002) and student proportion (RR = 1.0186) influence the morbidity rates of Hypertension and Ischemic heart disease. Hypertension and Ischemic maps are easy for readers to see which areas are at high risk. They are a useful tool for planning and controlling the Hypertension and Ischemic heart disease.

This article presents the application of the constant Volts per Hertz control to control a three phase induction motor has torque and speed characteristics similar to wind turbine. Due to this method is not complicated and does not require the parameters of motor. As a result the accuracy of control is independent of variation of the parameters of motor. Furthermore the equation for compensate the difference between the moment of inertia of wind turbine and motor which is consistent with the mentioned control method is proposed. In order to make the dynamic responses of the wind turbine simulator similar to the wind turbine and to overcome the problems of noise amplification from differentiation that leads to instability of the system. The simulation results in Matlab/Simulink program show that the proposed wind turbine simulator can imitate the wind turbine accurately both in dynamic and steady state conditions

This research was to apply graphical method as the input data combined with using database for developing reinforced concrete slab analysis and design. Visual Basic language was used for creating the GUI (graphic user interface) and coding and database file was used for storing data. The position of beam column and slab can define by drawing on GUI and this program will automatic translate to be the distances for using as data in process of analysis and slab design. Results from analysis and design were compared with manual calculation that they are a litter bit error because of rounding error. Moreover they can be more economically and more conveniently than results from VisStructure 4
