Abstract:

This research conducted a series of experiments to examine electrokinetic performance on dewatering and settlement in soft clay subjected to two configurations of electrode including: 1) anode and cathode were placed at top and bottom boundaries respectively, and vice versa for the other configuration. These configurations were later labeled as 1AT and 1AB, respectively. It was found that the 1AB yielded the best result in terms of settlement (27.08 mm). It was concluded that the influence of electrophoresis and gravity played roles in the magnitude of settlement. Due to the upward moving of clay particles during settlement (influence of electrophoresis), placing an anode above a cathode would generate cracks that interfere with the drainage of water and, hence settlement. This study also confirms that soil dewatering is governed by electro-osmosis process rather than effect of temperature. The reduction of water content during the experiment affects the efficiency of electrokinetic technique, including electric current and electrical resistance. As such, this technique is suitable for any problem that requires a smaller amount of dewatering within the very short time period.

Abstract:

This paper aims to create the model for student in choosing an emphasized track of student majoring in computer science at Suan Sunandha Rajabhat University. The objective of this research is to develop the suggested system using data mining technique to analyze knowledge and conduct decision rules. Such relationships can be used to demonstrate the reasonableness of student choosing a track as well as to support his/her decision and the system is verified by experts in the field. The sampling is from student of computer science based on the system and the questionnaire to see the satisfaction. The system result is found to be satisfactory by both experts and student as well.
