This research objective was to design the ginger candy compression machine and determine the efficiency and capacity for saving time and labor in pressing ginger candy for community enterprise groups Pim Malaherb Chiang Rai Province. Ginger candy compression machine consists of the main structure namely the extruder and power transmission systems. The machine was designed with two horsepower motors or 1.5 kilowatts to drive the shaft and to rotate the screw through the flange. This study installs the inverter to control the motor speed at 1000±10 1200±10 and 1400±10 rpm. The extrusion die had an average diameter of 9.7 millimeters. The results found that the motors speed that was suitable for compression was a Rotational speed of 1400±10 rpm. When the speed increased the efficiency and the working rate increased too. The amount of ginger stirred was used at 300 500 600 900 1000 1500 2000 and 3000 grams. The maximum efficiency was 90.85 percent. The efficiency increased with the amount of ginger stirred. The ginger candy compression machines engineering economic analysis results found that the machines operating cost was 18063.6 baht per year. When considering the machines operation at 792 hours per year the payback period was 6 months and 11 days.

This research has focused on the efficiency of using online media computer graphics based on concepts and theories of learning networks for students in computer science faculty of science and technology Rajamangala University of technology Phra nakhon because at present the network access can be accessed anytime the researcher has the idea to measure the effectiveness of learning in computer graphic courses. that students will have much interest 1) The population of this study consisted of 30 undergraduate students who attended the Computer Education and Training subject. The instruments utilized to design the lesson included. Tools used to develop lessons consist of a system LMS 2) The tools employed in evaluating quality of the online lesson consisted of the learning management plans a 20-item pre-and post-test an authentic assessment with rubric scores and a students’ satisfaction questionnaire. The results revealed that 1) The efficiency of the online lesson constructed was at 85/84 which was higher than the criterion set (80/80) 2) The students’ learning achievement was higher at .05 level of significance 3) The students’ satisfaction on the online lesson was at high level 4.31

This research aims to evaluate performance ease of use and security of designer bathroom for People with Visual Impairment. To establish criteria for designing bathrooms for people with visual impairment convenient and secure. The testing of bathroom designed for People with Visual Impairment in the ease of use and safety. From a sample of 30 people from evaluating the performance of People with Visual Impairment bathroom. To establish design criteria have been concluded. Orientation access various functions within the toilet should be placed in a triangular pattern. The size of the space available in each section should have a width close to reaching both the left and right or 1:00 to 1:20 meters approximately which led to the creation of the navigation functions. The surface should look different. But both have the same floor area. Case in point empirically for various functions. Use a light spot Or wall colors yellow orange To those who have blurred vision. Use more convenient The height of the counter should not be less than 0.80 meters so that disabled people have to stoop so dangerous. Detailed breakdown of wet and dry areas. The slope should be greater than the lower level. Or the waterproof (CURB) distance from the gate to reach the final (toilet) should be approximately 2:00 to 2:40 meters that should enhance security by using the cushioning material at the wall. Edge counters And bidets The research was to evaluate the efficiency of People with Visual Impairment bathroom. To establish design criteria To be appropriate And safe to use From designing a bathroom for People with Visual Impairment. The result is a conclusion from the test sample only preliminary. The need for additional testing of water and three forms or compare with typical bathroom. From a diverse group of users to have a complete research results and to determine the design criteria occur.

This research is aimed to establish the small wireless sensor network under the real environment. The objectives this research is aimed to study the data transmission and evaluate the data transmission performance of RPL protocol in wireless sensor network. Four nodes of wireless sensor network have been installation and transmissions between nodes in single-hop and multi-hop have been simulation for testing and analyzing data from the network following the transmission performance index. The research found that the number of hop and building environment are the principle factor to the performance of RPL protocol this might be the major limit to implement the RPL protocol in wireless sensor network

This thesis proposes technical performance evaluation and economic decence for the combination of harmonic correction devices in Industry. Currently an electronic device is popularly applied in power network. Although it is a higher performance device than the existing device it still causes the power quality issues and then network failure. Especially harmonic disturbance in the network it is a harmonic source that generates harmonic current into the network. Many types and solutions are available in the present time therefore the suitable and optimal financial solution must be considered. A network model for the analysis of harmonic correction devices suitable solutions and optimal financial has been established in the simulation software that bases on the power and Break Even Point (BEP) equations. The results of analysis shown that the performance of harmonic correction devices suitable solution and BEP of investment in match to the using of a detuned filter bank and an active harmonic filter (case 8) thus these information will be valued for the end-user.
