Get PDFรายงานวิจัย -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2564This research presents the processing of fresh guava into guava juice product. to be kept for consumption and distribution in the local area It is an alternative career path that helps rural farmers earn more. and create additional careers for the family But farmers still lack the correct technology, tools and processing methods in each production process. Therefore, there was a problem of insufficient cleanliness, taking a lot of time, resulting in unacceptable quality and the production is low, the postharvest engineering research group has conducted research to find suitable guava juicer. This study is based on working principles of food processing equipment in general use. Come as a guideline to develop, improve and create prototypes. The original guava juicer was a grater roller squeezer. There is a guava-sized subsystem consisting of a sub-chamber with grated rollers and the waste water barrier system consists of a juice sieve chamber, a waste separation room, a spiral conveyer and a sweeper set. various parts that come in contact with the guava juice is made of stainless steel The power source uses a 1-horsepower electric motor, a single-phase electrical system, a voltage of 220 volts. The machine has the ability to block water at a rate of 250 kg / hour. The juice obtained must be filtered out again with a centrifugal bag filter capable of filtering water at a rate of 50 liters/hour. The prototype guava juice machine costs 40,000 baht, and the centrifugal filter bag costs 5,000 baht. With just one such machine, each of these machines can produce 28,000 liters of guava juice/year (112,000 bottles a year), able to get a return in 0.08 years, with an average processing cost of 4.48 baht/bottle, which is appropriate in engineering economics. In investment, use a ready-to-drink guava juice machine. Fresh guava ingredients are available throughout the year and have 200 business days/year.Rajamangala University of Technology Phra Nakho

At present, electric power is an important factor driving the country both in industry and transportation. The demand for electric power tends to increase, the production is insufficient to meet the demand. Therefore, it is necessary to make the most of the energy resources available in the system. An effective system must be analyzed to detect possible errors. A sudden increase or decrease in load in the system may result in inadequate production and distribution efficiency. Therefore, this project is presented for the analysis of power flow in a 3 bus, 5 bus and 30 bus power system model using a math simulation program. It is divided into 3 case studies: Case 1, power flow under normal conditions, Case 2, transmission line disconnection, Case 3, adding distributed power generation sources.Rajamangala University of Technology Phra Nakho

Most used in Bangkok, which is a popular vehicle. Therefore, this type of vehicle was chosen to collect data to study behavior and create a driving cycle the selection of the data collection route includes: Ratchadaphisek Road - Rama IV Road Phaholyothin Road and Rama III Road - Narathiwat Road, etc. Which the road is in the business district which has a heavy traffic volume. At present, there is an epidemic of Covid-19 the government therefore has measures to lockdown. It affects the traffic conditions greatly compared to the normal situation. Therefore, data collection was performed on-board measurement. and grouping the time series clustering. In the part of the equipment used to store data, including : KYOWA Model EDX-200A, It is a highly accurate data storage device. by connecting to Global Positioning System: GPS sensor and connect to notebook
The results of the data collection to create a driving cycle of 3 routes in the morning and evening (Peak time).It was found that most of the speed patterns used to create driving cycles were low speed patterns. The frequency of the speed range is close to the real driving and the speed range is in the range of 0-10 km/h. Which show that the traffic conditions on 3 routes are very dense. but driving in some parts can use speed and have the following movement patterns including : acceleration, deceleration,constant speed, stationary.

Thai fruit wholesaling. The objectives were to 1) study the level of focus on entrepreneurial
orientation, value creation, service innovation, and business performance of Thai fruit
wholesalers in Talaad Thai, Pathum Thani Province, 2) to create and test the structural
equation model of the entrepreneurial orientation, value creation, service innovation and
business performance of Thai fruit wholesalers in Talaad Thai, Pathum Thani Province,
3) to study the direct effect and indirect effect of entrepreneurial orientation, value creation,
and service innovation influencing the business performance of Thai fruit wholesalers in
Talaad Thai, Pathum Thani Province. The sample group used in this research consisted of
600 Thai fruit wholesalers in Talaad Thai, Khlong Nueng, Subdistrict Khlong Luang, District
Pathum Thani Province. The instrument used for the data collection was a questionnaire
using accidental sampling. Descriptive statistics such as frequency, percentage, mean,
standard deviation, and inferential statistics such as correlation coefficient (r) and structural
equation model (SEM) were used to evaluate the data. The research results revealed that the elements of the entrepreneurial orientation
factors, value creation, service innovation, and business performance were, on average, at
the highest level. When testing the relationship between every element in the entrepreneurial
orientation factor, value creation, service innovation, and the business performance were
found to have a statistically significant relationship. In the analysis of the structural equation
model (SEM), it was found that service innovation was directly influenced by entrepreneurial
orientation with a statistical significance of 0.01 with a coefficient of 0.877, and 77 percent
of causal variables were predicted. The business performance was directly influenced by
an entrepreneurial orientation, value creation and service innovation with 0.92, -0.49 and
0.49, respectively, indirectly influenced by entrepreneurial orientation with -0.064. The highest
total effect on entrepreneurial orientation was 0.880. The entrepreneurial orientation and
service innovation had a significant impact on business performance at 0.01 and had
predictive coefficients of 78% and 85%, respectively.Rajamangala University of Technology Phra Nakho

The Design of power harvester for passive RFID Tags
Get PDFRMUTP Research Journal, Vol. 16, No. 2, July-December 2022, pp.74-85This paper presents the design of a power harvester for passive RFID Tags. An impedance matching circuit chooses a high-pass L network inserted between the antenna and rectifier circuit to maximize the power transferred to Tags, using an impedance transformation technique. A simple circuit including only a shunt inductance was selected as a matching. The rectifier utilizes a Self-Vth-Cancellation (SVC) circuit is an archived self-threshold voltage cancellation and self-power regulation function with a simple circuit design. An antenna is modeled as an RF source with a series impedance Zs of 50Ω while the rectifier is modeled as a load impedance ZL, which is estimated from the process and design parameters of the NMOS and PMOS transistors used in the SVC rectifier. As the combined circuit was simulated using input in the UHF band of 953 MHz and the devices’ model of the 0.35μm CMOS technology. The simulation results were compared with the single-stage rectifier of the SVC technique in the issue of the Power Conversion Efficiency (PCE). The achieved DC output of the rectifier yields the power conversion efficiency of 43.7% at input RF power -10.22dBm while a DC output voltage of around 643.8mV and a current load of 64.4μA.Rajamangala University of Technology Phra Nakho
