To store electrical power from solar cells are generally used battery as storage. Recent development in capacitor technology achieves with higher capacitancc smaller and low cost especially dcvelopment of a supcr capacitor (doublc laycrs). This research study used a super capacitor to store electrical power from solar cells. The results show that super and electrolyte capacitor can be used without battery with more power density and fast charge. But capacitor discharging must be controlled. The important disadvantage is super capacitor is used with low voltage and high rate of charge leakage. In case of electrolytic capacitor can use with higher voltage low rate of charge leakage but lower capacitance.

We present the comparison of CDMA MAC protocol with and without beat noise by using 2-D optical CDMA MAC protocol over WDM networks. We use the asymmetric primehop sequence code. Moreover we analyse the effect of the number of available wavelengths in tenns ofaverage number of attempted to transmissions per time slot (offered load) and beat noise is considered. The presented numerical results based on the throughput and delay time versus the offered load. We divide into two parts. The first one we consider the effect of the number of available wavelengths. Another is the effect of with and without beat noise in the 2-D OCDMA over WDM systems.

The objectives of this special project study were to produce and develop an augmented reality storybook for children Boon Long in the City and measure user satisfaction of augmented reality story technology books for children Boon Long in the City. Using a after augmented reality storybook for children Boon Long in the City was created and validated. The book was put to test with a sample group of 30 aged between 3 - 6 years old obtained by a convenient random sampling technique. A set of questionnaires was used to collect data. After statistical analysed data results show overall satisfaction of the book at a high level with a mean of 2.85 a standard deviation of 0.35

The purposes of this research were 1) to study personal factors and family factors of High school students at Prakhanongpittayalai School. 2 ) To study food consumption patterns of high school students at Phrakhanongpittayalai School according to the new normal. 3) Comparison of food consumption patterns according to the new normal of high school students at Phrakhanongpittayalai School classified by personal factors. 4) Comparison of food consumption patterns according to the new normal of high school students at Phrakhanongpittayalai School classified by family factors. The sample was obtained by random sampling of 300 students from high school students at Phrakhanongpittayalai School and using online questionnaires as a research tool. The data were analyzed by using frequency percentage mean standard deviation t-test and one-way analysis of variance. The results revealed that 1) most of the samples are female age 18 years old studying in Mathayom 6 earning between 100- 150 baht per day. The housing types are townhouse apartment or flat. The number of family members is more than 3 people. The education level of their parents is lower than a Bachelors degree and work as employees with an average family income of 15000 – 30000 baht per month. 2 ) Food consumption patterns of high school students at Prakanongpittayalai School according to the new normal found that the overall level was at a high level. When considering each aspect it was found that the aspect with the highest mean was the perception of food consumption according to the new normal followed by the aspect of food consumption characteristics of the family according to the new normal and the least aspect was the food type selection according to the new normal. 3) Comparing dietary patterns of high school students at Prakanongpittayalai School according to the new normal classified by personal factors it was found that gender age educational level parental income per day and housing characteristics were significantly differed in opinions on consumption patterns at the . 05 level. 4) Comparison of dietary patterns according to the new normal classified by family factors found that the occupations of parents and the average family income per month haddifferent effects on the new normal dietary patterns of high school students at Phrakhanongppittayalai School. There was a statistically significant difference at the .05 level except for the number of family members and their parents’ education were not statistically different at the .05 level.
