This research presented an online approach to verify entire Thai Fingerprint through fingerprint scanner U.are.U 4000 model using Hausdorff Distance Technique for similarity measurements. The Fingerprint Verification Using Hausdorff Distance Technique system consists of image preprocessing minutia feature extraction from two type (ridge ending and bifurcation) and verification process. In the image preprocessing include brightness enhancement contrast enhancement orientation field frequency ridge gabor filtering binarization and thinning which are sufficient to enhance the image for feature extraction. Only features extraction was recorded for fingerprint verification. The experimental result demonstrates 93.33% of verification accuracy.

The purposes of this research were 1) the comparison of tie-dye methods; Binding technique folding technique and stitching technique and 2) three kinds of fabric dyed; cotton linen and rayon comparison and 2 pattern design groups; geometrics and naturalistic patterns. There are 8 motifs were used; quadrangle trianglecircle heart form flower leaf butterfly and worm. The research tools were used; The assessment for 15 connoisseurs (connoisseurship model). Data were analyzed by the statistical package for the social science program and using mean percentage standard deviation one-way ANOVA and chi-square.The result of the study were that binding technique had mean 4.20the second was stitching technique had mean 4.10 and the last was folding technique had 3.69. The result of the tie-dye technique suitability comparative ranking for massproduct that the best technique is binding. The second was stitching technique and the last was folding technique. In this study there were comparative in 5 parts as follows 1.tie-dye method 2. pattern design 3. colour of fabric dyed 4. overall image of fabric dyed 5. capability of techniques.Binding technique folding technique and stitching technique on Cotton were much points in tie-dye method and capability of techniques. Binding technique and stitching technique on Cotton were much points in pattern design and overall image of fabric dyed. Binding technique and stitching technique on Linen were much points in 5 parts. Folding technique on Linen were much points especially in tiedye method and capability of techniques. Binding technique and stitching technique on Rayon were much suitable in 5 parts. Folding technique on Rayon were much especial points in 5 parts except overall image of fabric dyed. Comparison of three kinds of fabric and two pattern groups were that cotton linen and rayon fabrics in geometrics and naturalistic patterns had average the best in binding technique. To compare tie-dye techniques and fabrics and pattern groups had different for some parts statistically significant at level of .05

The purpose of this research study is to investigate student’ attitude and evaluation on remedial program in Technical English 1. 10 subject in this experiment were each first-year Computer Technology and Mechanical Technology undergraduate students at Rajamangala University of Technology Phra Nakhon North Bangkok Campus. The group was divided into 2 groups of 5 student each according to their major subject. The group was divided into 2 groups of 5 students each according to their major subject. The instruments used for data collection were questionnaire and semi-structured interviews. When students learned English they used a remedial program through Web Based Instruction. The questionnaire and semi-structured interviews were given to the students after finishing the remedial program. The finding of this research study revealed that computer Technology undergraduate students used more e-Learning than Mechanical Technology students. Mechanical Technology undergraduate students attitude toward the remedial program are more positive than Computer Technology undergraduate students. Both groups were satisfied with respondent evaluation immediately. Suggestions and implications concerning how to adapt the remedial program through website and how to use e-Learning are give.

Bifurcation diagram is an important mathematical tool for the analysis of ferroresonance in the electrical power system. Bifurcation diagram can clearly present the behaviors of the nonlinear system. The general method for the generation of steady state bifurcation diagram is based on Ordinary Differential Equation (ODE) of the simplified single-phase circuit and the continuation technique. This paper proposes the application of PSCAD/EMTDC simulation program and the bruteforce technique to generate time response of the three-phase power system. A new device tool “Multiple Poincaré Map” is created and used with File Read and XY Plot to produce bifurcation di agrams with respect to changes of controlled parameters. Two examples related to ferroresonances in the distribution systems are presented. Bifurcation diagrams generated with the PSCAD/EMTDC and Multiple Poincaré Map confirm that the results from the simulation are in good agreement with the results from field tests.
