This study applied the kunzelstab penetration Test (KPT) or Light Penetrometer to examined penetration resistance values geological profiles and estimate shear strength properties of soils. KPT tests were carried out on steep slopes that exhibit potential slope movement in Chiang Rai province. The principal uses of the KPT are examined; i.e. correction method for N’KPT’ soil profile and allowable bearing capacity of soil foundation. KPT tests were conducted at 13 boreholes each measuring 4.00 m long along the crown of the slope. The results indicated the compacted layer and located the firm layer of soil foundation. The average allowable bearing capacities were 1.53 t/m2 at depth of 1.00-5.00 m and 17.06 t/m2 for 5.00-6.00 m depth respectively. Furthermore this paper presents an analysis of the stability of a slope with the shear strength parameters of the soil and the geological profile were defined based on the results of KPT. The results of factor of safety were below the stable value for analysis cases with groundwater table. Test results demonstrate the usefulness of the KPT method in geotechnical investigations to estimate soil profile and bearing capacity efficiently and economically. This approach is also less time consuming compared to other geotechnical site investigation methods.

The objective of this research to study the basic formulas of tamarind paste products. The results of the study were as follows. The evaluated for likeness as 9-point hedonic scale by an untrained 50 member panel. Consumers rate the taste of tamarind paste at a very like level (8). Subsequently Tamarind substitution of 25 50 and 75% by weight of tamarind was found at the level of 75% substitution. Basic tamarind paste has a pH value of 4.20. Tamarind with karanda of 4.49 (p <0.05). Basic tamarind paste has water activity (aw) of 0.81 and tamarind with karanda of 0.83 (p> 0.05). The color of the basic tamarind paste was L * (brightness) (37.0) a * (redness) (5.26) b * (yellow) (12.28) (P> 0.05) The chemical compositions of tamarind with karnda were 237 kilocalories of total energy 10.7 percent of protein 11.5 percent of fat 10.7 percent of ash 4.77 percent of carbohydrates 23.7 percent of dietary fiber 5.20 percent of moisture 49.3 percent Iron content 1.71% total phenolic compounds 1.49 mg / g gallic acid and antioxidant activity 4.6

This research aimed to investigate the basic recipe product the quantity of banana flour that used instead wheat flour in Thai crispy sponge cake (Sa Lee Krob) and the nutrition value of Sa Lee Krob. 50 samples were expert lecturers from the department of food and nutrition the department of food science and nutrition and the department of industrial food service the faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon. 9- point hedonic scale was used in this study. The result found that the basic of 3th recipe (Bloggang 2018) was acceptable as the standard recipe. There were 4 levels of the substitution of banana flour for wheat flour; 0% 10% 20 % and 30%. 10% was acceptable for the appearance color flavor taste texture and overall liking. The average scores were 7.94 7.92 8.22ม 7.90 and 8.08 respectively. For the color of the basic Sa Lee Krob L* (brightness value) a* (redness value) and b* (yellow value) were different from Sa Lee Krob which is substituted with banana flour (p≤0.05) For the texture of basic recipe of Sa Lee Krob the hardness value was harder than Sa Lee Krob which was substituted with banana flour. The flexibility value ability to combine stickiness value and Chewing resistance value were not significantly different (p>0.05). The nutritional aspects of the basic Sa Lee Krob and the quantity of banana flour substituted wheat flour found that provided less energy but more fiber. The more ash showed that banana flour provided more quantity minerals. Minerals found in banana include potassium magnesium phosphorus and calcium.

This thesis proposes a method for detecting harmonics current in the adaptive active harmonic filter with Recursive Least Square (RLS) algorithm. The proposed method is based on the theory of noise cancellation adaptive filter. Originally the theory was used for audio signal processing but this thesis is applied to the harmonic current detector of an active harmonic filter. The principle and construction of the harmonic current detector in the adaptive active harmonic current filter with Least Mean Square (LMS) algorithm and Recursive Least Square (RLS) algorithm are presented to compare the efficiency of both algorithms. Then simulate these two algorithms with Matlab-Simulink program to simulate the three case studies. All three case studies that simulate are generally available in industrial plants. The simulation results show that the harmonic current detector in the adaptive active harmonic current filter with the LMS algorithm and the RLS algorithm can detect the harmonic currents in the power systems. However the RLS algorithm is more efficient and has less error value than the LMS algorithm. Therefore it is confirmed that the RLS algorithm proposed in this thesis is appropriate to use with the adaptive active harmonic current filter to really work in the industry.

The research purposes were to analyze and search for wastes in the planning process and transportation of the automobile parts of a transport company in Samut Prakan using Makigami Lean and ECRS Techniques. The informants used in this study were the support staff working the planning process and automobile part transportation for the car assembly factory in the industrial estate Rayong Eastern Seaboard. Six employees from different work units took part in the in-depth interview as the research tool for the data collection. Statistics used in the data analysis including percentage and workflow analysis with related management tools. The study indicated that searching for the waste in the technical planning process with Makigami Lean and ECRS Techniques could help reduce the work time for 1060 minutes in each step.
