This research is to develop a prototype of a salinity intrusion monitoring system using fuzzy logic to extract salinity values. A system is developed according to a fuzzy logic model using FAOs for appropriate agricultural water quality data considering the electrical conductivity (EC) and total dissolved solids (TDS) as indicators of the salinity value by using the Fuzzy Logic Toolbox to produce and test the generated model. Transformation of the generated models to Embedded C format using the Simulink Coder tool installed in the ARM STM32F microcontroller and a 10-fold cross-validation test was used to validate the data extraction. The Root Mean Square Error (RMSE) for the test results was 0.58175 on average. This research result indicates that the generated model is able to extract data that very closely matches the specified data.

Developing women’s clothing design from marigold-dyed linen. The objectives of the project were : 1) to study about linen dying technique with marigold with various kinds of mordant 2) to design and develop women’s clothing from marigold-dyed linen 3) to study the satisfaction of representative samples for the women’s clothing design from marigold-dyed linen. Using simple random sampling method analyzing the data with statistics percentage mean and deviation standard. The sample groups are selected from working women in Dusit District Suan Chitlada Subdistrict and students from Rajamangala University of Technology Phra Nakhon in total 100 participants. Research instruments are questionnaire and 2 women’s clothing prototypes one was dyed with natural mordant and the other chemical mordant. The results indicated that most of the samples aged from 25 and above single graduated with bachelor degree are general office workers and students and earn less than 15000 baht. The result also revealed the satisfaction for the women’s clothing design from marigold-dyed linen a design which was dyed with both natural and chemical mordant. The participants are satisfied with the modern design suited for working age and very useful at a high level with means of 4.07 and 4.05 natural and chemical mordant respectively. Considering the overall result the participant tended to be satisfied with natural mordant dyed dress more with a mean of 4.07

The purpose of this research was to study the dyeing polyamide/elastane fabric with natural indigo using exhaustion dyeing process. The effects from the concentration of the natural indigo dye thiourea dioxide and sodium hydroxide were investigated. The colour of each dyed material was investigated in term of the CIELAB (L* a* and b*) and K/S value. The color fastness to washing rubbing perspirdation light water sea water and chlorinated water of the dyed samples was determined. The bursting strengrh of dyed polyamide/elastane was evaluated. The best vatting condition was at 50 ̊C for 30 minutes. The optimal formula of dyeing polyamide/elastane fabric using natural indigo was prepared by mixing 200 g/L natural indigo paste 60 g/L thiourea dioxide 1 g/L sodium hydroxide. The fabric dyed in the solution of indigo vatting a shade of dark blue colour. The color fastness to light washing water sea water perspiration and chlorinated water were good to very good. However the rubbing fastness results showed fair level. The bursting strength of dyed fabrics is less than the undyed fabric 3.1%. The optimal ratio of discharge printing on polyamide/elastane fabric were compose of 70 % starch print paste and 30 % discharging agent (KMnO4). The pattern design produced from these combinations in the printing areas on fabrics showed an excellent standard of printing quality. The results confirmed that natural indigo dyes have potential applications in polyamide/elastane fabric dyeing and the dyed fabric can be used produce women’s intimate apparel.

Nowadays Eye tracking technology is the next challenges of human computer interaction (HCI). This technology can help people all over the worldaccess computers through systems that use gaze control and especially important for people with physical disability. This research presents a system of assistive technology base on an eye-tracking interface while supported the communication system for independent living of persons with disabilities usability. The primary method of this system consists of a selection of pictogram buttons on three websites which used a low-cost eye-tracking device. The evaluation used the throughput of standards for computer pointing devices as a measurement of user performance to look at an on-screen target and dwell on it for 500ms for selection. The results showed that ten participants with a disability can be pointing and selection their overall mean throughput was 1.08 bits/s. Moreover the overall users of respondents were rather satisfied with the system. Consequently eye tracking technology is a great tool for interaction in the web application for a user with a disability.

Over the past decade eye-tracking technology can help people all over the world access computers through systems that use gaze control. For people with disabilities this technology is a gateway to communication personal expression and inclusion in society. Eye-tracking technology advance has been transferred to the educational area and now the use of interacting with the multimedia materials and resources in the classroom. The objectives of this research are threefold. The first study presented the development of a low-cost eye-tracking device based on video-oculography. The second study examined various factors in which eye movements can be systematically measured to design appropriate of usability in computer-assisted instruction (CAI). The third study created and determine the efficiency of computer-assisted instruction interactive with eyes lesson on knowledge of ASEAN in elementary education for a student with disabled hand control. This research has looked at three design parameters of the dwell-time click alternative interactive button size and placement of the button which suitable for eye tracking interfaces. The evaluation carried out an experiment to compare performance with five students with a disability. Results showed that a combination of big buttons and short dwell-times are most suited for maximizing accuracy and ease of use. Furthermore the efficiency of computer-assisted instruction is 70.0/71.5 and the user’s satisfaction with CAI were at the high level ( =4.27 S.D. 0.79). Consequently eye tracking technology is a great tool to interaction in computer-assisted instruction for Thai students with a disability. x
