The objective of this paper is to construct the solar car prototype. The car uses flexible solar panels with the battery as a power source. Thereafter the performance of the solar car is tested in the actual condition. This solar car’s body was developed by fiberglass and the internal structure was made from the steel. This car uses the 2 kW brushless DC motor to be the prime mover and the motor is driven by the regenerative dc converter. The power sources are 480 watts of the flexible solar panel with a charger to charge power to four of 12V 33Ah battery. The total weight of the solar car is 173 kg. The solar car’s weight including driver is about 233.4 kg. The solar car test drive is on 10 km distance. The result found that the car has: (1) the average speed is equal to 45.98km/h by using only battery (2) the average speed is equal to 51 km/h when the battery is combined with solar panels. This knowledge should be applied to develop the next version of the solar racing car.

The Purpose of this research is to study the Usage and Satisfaction towards Internet of Students at Rajamangala University of Technology Pra Nakorn. This study is a survey research. The instruments used in this research are questionnaire. The sample groups in this research were Rajamangala University of Technology Phra Nakhon 400 persons.

The objectives of this research were to 1) study perceived problems of students for educational management of Home Economics Technology Faculty Rajamanga la University of Technology Phranakhon 2) compare perceived problems of students for educational management classified by gender students year and field of study and 3) study needs of students for educational management of Home Economics Technology Faculty The sample studied were 291 undergraduate students selected by proportional stratified random sampling categorized by students year of study and simple random sampling was also used The data was collected through questionnaires constructed by researcher The statistics used for data analysis were mean standard deviation one way analysis of variance and Scheffes multiple comparison method The results were as follows : 1 Problems concerning instructors content of study and method of teaching were less perceived by students Evaluation and measurement teaching and learning management and instructional media and instruments were perceived as problems at intermediate level The high perceived problems of students were infrastructure concerns particularly the lack of gymnasium stadium and first-aid centre 2 Students from different year and field of study and were different gender had statistically difference of perceived problems for educational management. 3 The highest needs for educational management concerning instructor aspect was lending equity to all students Regarding the aspects of study contents method of teaching evaluation and measurement and teaching -learning management the highest needs were complete and update knowledge practical based teaching evaluating after teaching and appropriate study schedule respectively Enough and clean toilet as well as enough educational equipments were the highest needs for the aspects of infrastructure and educational media and instrument respectively

In this paper we have analyzed the performance of combining security system (SSL Protocol) with current TCP/IP module by porting security shareware into the EDC (Electronic Data Capture) devices. Finally in order to understand the impact on the EDC’s performance we test the throughput of the EDC before and after applying security with various encryption algorithms.
