This research analyzes the parameters affecting the penetrating resistance of shells on the armor surface by the finite element method. In this study the results were compared with real bulletproof armor firing tests and finite element simulations. modeling of bulletproof and bulletproof armor using Solid Works program. Creating and simulating armor firing pattern using ANSYS Explicit Dynamic program. damage test is based on National Institute of Justice (NIJ) level 3 standards with bullets the material of the ammunition is 7.62 mm tungsten carbide (WC). there are two types of bulletproof armor used in this simulation 1) SKD11 2) Aluminum AL7075. The simulations is into 1 category Simulation of stacked armor plates. The sizes of the armor plates are 6 8 and 10 mm and the angles of firing of bulletproof armor are 0 30 and 45 degrees. result of this simulation armor thickness and firing angle are factors of penetration resistance.

The purpose of this project is to construct a horizontal electric train controlled by the Arduino. For the cost that is cheaper than the market and users can be self - reliant in daily life In which the car size is equal to the electric train that is sold in the general market. The organizers can write an arduino program to control the movement of the car from the joystick lever. The built weighing 25 kilograms is powered by a 12 volt battery that provides power to the circuit to control the direction of the car. The car can support a maximum weight of 100 kilograms and can be adjusted to more than 160 degrees. Experimental results Found that the operation of the electric train is adjustable controlled by Arduino Able to work according to objectives. This Arduino - style electric train can adjust the sitting position to your desired position. The control to change direction can be forced forward backward left right turn from the lever from the joystick as needed. As for the road characteristics it can be used as smooth and sloping roads.

This thesis emphasizes the improvement approaches of quality on digital data to be more sharpness by two- dimensional technique. Today the availability from the improvement of Digital Image Processing is used widely in various occupations such as medical field with reading the results from CT scanning military field with the improvement of aerial map for country prevention agricultural field with leaf analysis of its disease and the educational field with the image processing and robot vision to increase its effective learning and remembering development. It can be seen that the image development through its sharpness is really crucial therefore this thesis used the Gray Scale for transforming by two-dimensional wavelet and LL Band got from this wavelet transform to be improved by histogram technique. The histogram was divided into 4 parts based on its cumulative density at 0.25 0.5 0.75 and 1 then smoothed the data by separation after that brought the results to invert wavelet which gives the new image through improved LL band. The research result revealed that the mean of the Absolute Mean Brightness Error (AMBE) was decreased while enable the image sharpness to suitably increase 80%.

. This research aimed to study the acidification processes of carving vegetable using acid conditioning machine under emperature and pressure control which was developed in this study. Four acidification procedures were done at normal atmospheric pressure (method 1) under vacuum pressure for 10 (method 2) and 20 min (method 3) and vacuum pressure alternating with normal atmospheric pressure for each of 1 hour. There were two main parts of acid conditioning machine including the temperature controller inside the pickle tank and heat conductor tank and the pressure controller inside the pickle tank. The pickling temperature was stabled at 40oC under the pressure of 0.5 Bar. PLC (Programmable Logic Controller) program was used to write the ladder for controlling all processes and display through SCADA system. The results showed that the acidification method by soaking the carved-rose carrot under vacuum pressure alternating with normal atmospheric pressure showed the shortest time to equilibrium by 7 hours. Then the carved-rose carrot was packed in the glass jar followed by sterilized in boiling water for 15 minutes and stored at room temperature for 7 days. Total bacteria count Escherichia coli and Yeast-mold were not exceeded than the standard limit. Staphylococcus aureus was not detected throughout the storage periods

In spite of the copyright law in Thailand where distributing or obtaining a copyrighted work without the permission of the copyright holder is against the law illegal streaming and downloading of music is dramatically increasing. This changing behaviour of consumers has an incredible impact on the music industry as a whole. Our paper analyses the influence of intellectual property infringement on Thailand’s music industry income. The research tools employed in this study are a questionnaire and an in-depth interview to enable analysis. We found that after the evolution of musical technology in the 1990s internet-based music consumption has become significantly more popular and increasingly consumers are streaming sharing and discovering digital music all across the globe including in Thailand. With this new development of digital music the dynamics of the music industry have been affected significantly both in terms of income and number of entrepreneurs. Multiple regression analysis results show that the amount of unauthorized downloading of copyrighted music has a negative effect on Thailand’s music industry income. In contrast the number of property disputes from illegal downloading of copyrighted music has a positive effect on this industry income. The results suggest that entrepreneurs should pay attention to warranty information on products and prices and security of financial transactions in order to encourage consumer authorized online purchasing. In addition law enforcement can help achieve the goal of decreasing online music piracy.
