This research is Design and Development of Online Network. Providing the Academic Community with the Faculty of Architecture and Design. Rajamangala University of Technology Phra Nakhon. The purpose is 1) To develop online network. Community-based academic service to the Faculty of Architecture and Design 2 ) To design the image of the website. Networking Community-based academic service to the Faculty of Architecture and Design 3 ) To test and evaluate online network performance. Community-based academic service to the Faculty of Architecture and Design Rajamangala University of Technology Phra Nakhon The data was randomly sampling from 240 users and was analyzed by frequency average standardization and ranking.The research finds that the overall satisfaction toward the website development of the manager faculty were moderately at excellent level 4.58 and the standard deviation ofIt also found that the first satisfaction level toward website was in the content and graphic and overall satisfaction of specialist were moderately at good level 4.37 and the standard deviation of 0.69
การพัฒนาคุณสมบัติของต้นแบบแผ่นมวลเบาจากเศษใยยางพาราและเถ้าไม้ยางพาราสำหรับประยุกต์ในระดับภาคสนาม
The development of lightweight flat sheet prototype from para rubber leaves and para para rubber wood fly ash for field work application can offer an alternative method of adding value to agricultural wastes and help to conserve the environment with green products. The natural fiber especially agricultural waste fiber is an encouraging prospect. Natural fiber composites have been used for building applications. The aim of this research was to investigate the potential use of para wood ash to producing a cement composite as an environmentally material. Material. The cement paste with 5-2 % weight of para wood ash. The specimens were cured at 25± 2 oc for 24 hours. The properties of cement composites mixed with different proportions of para wood ash were compared with Ordinary Portland Cement (OPC). In addition the morphology of para wood ash was examined by using scanning electron microscope. The density increased with the increase in the percentage of para rubber leaves from 1% 2% 4% and 6%. The finding is attributable to the enhanced packing density by the fine para wood ash particles size was found 5-10 um.Moreover para wood ash particles could arrange to fill the inter-particle voids in cement pastes which resulting to increase the compressive strength of cement paste. Consequently para wood ashes could incorporate in the construction materials to enhance the mechanical properties and durability performance of the cement composites
การสร้างคุณค่าร่วมที่มีผลต่อการตัดสินใจเลือกใช้บริการเครือข่ายโทรศัพท์เคลื่อนที่
The objectives of this research is to study (1) The demographic of mobile users effected to mobile network’s decision making (2) The creating shared value of mobile network effected to mobile network users’ decision making. The sample population consisted of one thousand two hundred mobile network users. The instrument of research was a questionnaire. The Statistical Package for the Social Sciences (SPSS) for Windows computer program was applied for analyzing formulating and tabulating the data collected. The techniques of descriptive statistics used were percentage mean and standard deviation. Techniques of inferential statistics utilized were t-test one-way analysis of variance (ANOVA) in order to analyze differences between variables taken as a group. If there is a statistically significant differences found between pairs in a group Scheffé’s pair testing were deployed. Multiple Regression Analysis were applied in order to analyze the demographic of mobile users and creating shared value of mobile network effected to mobile network users’ decision making. The results were as following: 1. The all factor demographic of mobile users effected to mobile network’s decision making effected to mobile network’s decision making. 2. The creating shared value of 3 brands effected to mobile network’s decision making effected to mobile network’s decision making.
การพัฒนาเถ้าแกลบและเถ้าถ่านหินเพื่อใช้แทนที่ปูนซีเมนต์ปอร์ตแลนด์ในงานคอนกรีตกำลังสูง
This research presents a study of the use of classified fly ash and ground rice husk ash as a pozzolanic material in producing high-strength concrete. Portland cement (CT) is partially replaced with classified fly ash and ground rice husk ash by weight of the cementitious materials. Compressive strength porosity and chloride penetration were investigated. The results show that the compressive strength resistance to chloride and low porosity of high-strength concrete improves substantially with partial replacement of Portland cement with fly ash and rice husk ash.
การศึกษากระบวนการทำงานของ Mirai botnet ในความปลอดภัยด้านไซเบอร์ของ มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร
This research aims to study the Mirai Botnet working process which made high bandwidth impacted to Internet system. From 90000 clients of Deutsche Telekom cannot access to Internet that overall bandwidth growth nearly 1 TB per second in the history DDoS attacking behavior. As Mirai exaggerated attacking to ISPs and may be involved UniNet as a big umbrella which RMUTP network interconnected as well. The author would like to study in depth to several weak points of the end devices or IoT on Internet. In the Mirai code used the IoT devices such as the Internet cameras the CPUs based on ARM ARM7 Motorola 6800 SPC PowerPC X86 and SuperH (SH4). As the results of valuable attacking code studied based-on IPV4 attack without IPV6. The source code has more than 5500 lines with 16 files and 138 functions included 62 set of user accounts and passwords. Usage the 9 flooding techniques for port attacking via 22 23 and 80 with the IP scanning exceptions for DoD IANA GE and HP IP addresses. The Internet camera devices have to disable 22 23 and 80 ports or doing suitable usability techniques to manage for several flooding protection from system harmfully.
