The objectives of this study were 1) to study the basic formula of Bean-Based Meat Analogue Products Supplemented. 2) To study the appropriate amount of lotus root utilization as supplementation in bean-based meat analogue products and to study the nutritional value of bean-based meat analogue products supplemented with lotus root. 3) To study the acceptance of bean-based meat analogue products supplemented with lotus root. 4) To study the consumer acceptance of bean-based meat analogue products recipes supplemented with lotus root. The results showed that the basic formulation of bean-based meat analogue in the recipe 2 which contains 50 grams of soybeans 60 grams of green peas 40 grams of white beans 10 grams of shiitake mushrooms and 5 grams of beetroot was the most accepted by 5 experts. The results of sensory evaluation showed that lotus root supplementation in a 10% bean-based meat analogue formulation was statistically significantly higher than that of 5% 15% and 20% lotus root supplementation (p≤.05). The results of the calculation by software package showed that the amount of dietary fiber in the basic formula was 15.56 gram which was lower than the formula that supplemented with lotus root. The amount of protein in the basic formula was 41.40 grams which was lower than the lotus root fortified formula. The results of a consumer acceptance test of 30 people using the 9-Point Hedonic Scale rating method showed that the majority of consumers liked the shape and color. As for the taste smell texture and overall liking it was at a moderate level of acceptance and 93.33% accepted the bean-based

his project presents a power flow analysis model for the purpose of studying power flow in a power system model. 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.

This research aims to study how the level of excellence in the accounting profession and the usage of artificial intelligence technology affect the quality of financial reports of certified accounting practice. For the data collection the researcher used questionnaires. The population examined in this research consisted of 88 accountants working for high-quality accounting firms registered in Thailand. Descriptive statistics namely frequency percentage mean and standard deviation and inferential statistics including Pearson’s Correlation Coefficient and Multiple Regression Analysis were used to analyze the data. The study results reveal that accountants registered and working in high-quality accounting firms in Thailand reach a high degree of excellence overall. Furthermore artificial intelligence technology allows these accountants to positively affect the overall financial report quality at the highest level. The results of the research hypothesis test found that: 1) excellence in the accounting profession positively affects the quality of financial reports both overall and in every individual aspect and the result is statistically significant at the 0.01 level; 2) the use of artificial intelligence technology positively impacts the quality of financial reports both overall and in the individual aspect and the result is statistically significant at the 0.01 level.

This thesis was an analysis of the significance of angle of inclination and the thickness of the armor plate on the penetration resistance of bullets on aluminum and stainless steel armor plates determined by the finite element method. In this study the information results obtained from actual firing of bulletproof armor and the finite element simulation according to NIJ 3 standards were compared to create a pattern of bulletproof and bulletproof armor using the SolidWorks program. The simulation model of the armor shooting was created by the Ansys/Explicit Dynamics program. The bullet material was 7.62 mm tungsten carbide (WC). There were three plate types used in the simulation were made of different bulletproof armor materials: 1) stainless steel SUS304 using for the plate thickness of 5 6 8 10 14 20 30 40 45 and 55 mm. 2) aluminum AL7075 using for the plate thicknesses of 6 8 10 and 20 mm. Additionally 3) tungsten carbide using for the plate thicknesses of 6 8 and 10 mm. Each of these plates had a width x length of 300 x 300 mm. The simulation models were divided into two types: Type 1 a simulation firing at one plate at a time. Type II a simulation firing at two layered plates stacked together without any gaps between plates. The front and the back plates made of stainless steel and aluminum respectively or tungsten carbide and stainless steel respectively were determined. The angles of firing at bulletproof armor were set at 0 30 and 45 degrees. The output results were that in Type I the stainless-steel plate with a thickness of 30 mm or more could resist the penetration of bullets. However in Type II 2 stacked layers of the armor plates using the front stainless plate with a thickness of only 20 mm and the back aluminum plate with a thickness of only 8 mm could provide the same constructive results as those of tungsten carbide and stainless steel plates for the front and back plates with both thickness setting at 16 mm. All of them showed the resistance of the penetration to the bullets. More observation was that the increases in angles as a result enhanced more resistance of the bulletproof plates to bullet penetration.

This research project aimed to analyze and design the pattern of a bulletproof metal armor plate as well as build a bulletproof metal armor plate for a small armored regular truck. The methodology consisted of the NIJ standard test and the finite element analysis. The bulletproof plates created were tested for a real firing. Their firing results were compared with those of NIJ-standard using a finite element program in this case applying with the program Ansys/Explicit Dynamic. SolidWorks program is employed as a tool to design and create 3D models of armor plates and bullets. The materials taken in the finite element simulation were SKD11 and SUS304 and the parameters utilized in the research were material types hardness values spacing between the plates and thickness. In the case of two armor plates stacked SKD11 material was designed for the first armor plate to be hit by the bullet. It served to destroy bullets. In addition the second armor plate made of SUS304 material served to absorb energy and obstruct the movement of bullets. For testing a 30-06 caliber M2 AP 166 Gr bullet was selected at a 0-degree angle and the velocities measured and set by the Ansys/Explicit Dynamic program were 901.7 m/s and 880 m/s respectively. The front plate made of SKD11 material with a thickness of 10 mm and the back plate made of SUS304 material with a thickness of 10 mm were fired 1 shot. The results showed that the bullet could penetrate the front armor plate but not penetrate the back-armor plate. In the NIJ 3 standard tests the shooting with a 7.62x51 mm NATO FMJ 148 Gr shell at a 0-degree angle for 5 times with velocities equal to 846.4 841.3 839.1 838.2 and 845.3 m/s was performed on the stacking front and back armor plates both made of SUS304 material with a thickness of 8 mm. The bullet velocity simulated by the Ansys program was 847 m/s resulting in the front plate having a bullet penetration and a slight bulge on the back plate. From the finite element simulation results and the actual test results it was found that the damage to the armor plates detected by both methods was consistent. Therefore the finite element program was selected to simulate the damage of armor plates resistant to penetration according to the NIJ standard Level 4. The results of the research could be concluded that the use of armor plates stacked with suitable different materials in multiple layers would affect the penetration resistance. Increased thickness and optimal spacing between the armor plates were important parameters in penetration resistance. Moreover it revealed that the higher the material hardness the better its ability to resist penetration. In particular this suggestion should be applied to the first armor plate or front armor plate.
