Preparation of Bioethanol from Brown Seaweed Sargassum Sp.

In this study, brown seaweed Sargassum sp. was used to produce bioethanol by using enzymatic liquefaction and saccharification method. Bioethanol from brown seaweed Sargassum sp. was more commercial than using any other starch based raw materials because it can be easily collected on Chaung Tha beach in Myanmar without any impact on environment. In this regard, the productivity of bioethanol from brown seaweed Sargassum sp. was determined by separate hydrolysis and fermentation SHF with yeasts. Two types of yeasts were used. Saccharomyces cerevisiae was used for glucose fermentation in brown seaweed and selected nitrogen fixing yeast isolate N3,N18,N24 were used for mannitol fermentation which consist plenty in brown seaweed. The effects of enzymatic liquefaction, enzymatic saccharification and fermentation on this sample were studied. From the fermentation studies, brown seaweed Sargassum sp. gave the ethanol percent by weight of 2.56 using Saccharomyces cerevisiae only and 4.1 by using mixture of yeast Saccharomyces cerevisiae and selected nitrogen fixing yeast isolate. The maximum yield of crude ethanol was 32.5 by fermentating yeast mixture of Saccharomyces cerevisiae and nitrogen fixing yeast isolate. When it was fermented by just only Saccharomyces cerevisiae, yield of crude ethanol percent was 20.3.

Text Embedded System using LSB Method

An important topic in the exchange of confidential messages over the internet is the security of information conveyance. For instance, the producers and consumers of digital products are keen to know that their products are authentic and can be differentiated from those that are invalid. The science of encryption is the art of embedding data in audio files, images, videos or content in a way that would meet the above security needs. Steganography is a branch of data hiding science which aims to reach a describe level of security in the exchange of private military and commercial data which is not clear. This system is proposed to hide the text information files within the image based on the LSB method in order to meet security requirement such as confidential and integrity. The least significant bit is the bit which is farthest to the right and holds the least value in a multi bit binary number. This system is implemented by using C programming.

Speed Control System of Induction Motor by using Vector Control Method

In the Vector Control method of induction motors, one of the advantages of the separately excited DC motor of being able to decouple the flux control and the torque is thereby opened up. The field orientation control of induction motor allows decoupling the control of magnetic flux and the control of the torque produced by the stator current. To drive three phase squirrel cage induction motor with a constant speed, vector control technique is used. In this paper, the development of speed control system for three phase squirrel cage induction motor using a vector control method is presented and simulation for proposed system is done with the help of MATLAB SIMULINK.

Speed Control System for BLDC Motor by using Direct Back EMF Detection Mathod

BLDC motors are used in many industrial and traction applications due to high efficiency, low maintenance and high torque. For good performance of BLDC motors, the accurate knowledge of the rotor position is required. The need for the rotor position information in BLDC motors have been satisfied by use of some form of rotor position sensors. But to reduce cost, complexity and also to improve reliability of the system, sensor less drive system is preferred. In this paper, the development of sensor less control system for BLDC motor using a direct back EMF detection method is presented and simulation for proposed system is done with the help of MATLAB SIMULINK.

Design and Simulation of Automated Packaging Machine Process Control by Using PLC

Industry automation becomes the global trend in manufacturing and packaging process is one of the uses in industry. Modern industrial plants require the automatic process control system to control the desired process. The programmable logic controller PLC is very useful for the industrial automation in the modern business world. Industrial automation plays an important role in increasing the yield of a product. And then, among the controlling systems, the PLC control system has more applications than the other numerical control systems. It can be observed that a circuit has a fault by checking the control panel board. Troubleshooting can be done quickly visual observation. The main idea of the paper is to automate the process for packaging the detergent that weights 85 kg. Programmable logic controller SIEMENS SIMATIC S7 300 CPU 214C 2PN DP AC DC relay was used to control and automate this machine by ladder logic diagram software. In this paper, TIA portal V 13 software is used as programming software.

Design of Grounding System for Substation

This paper presents 230 66 kV, substation grounding system and calculation results of required parameters. The grounding system is essential to protect people working or walking in the vicinity of earthed facilities and equipments against the danger of electric shock. This paper provides the floor surface either assures an effective insulation from earth potential or effectively equipment to a close mesh grid. Calculations of grounding grid system in the substation area which the top soil layer resistivity is less than the bottom layer resistivity, can lessen the number of ground rod used in the grid because the value of Ground Potential Rise GPR is insignificantly different. Essential equations are used in the design of grounding system to get desired parameters such as touch and step voltage criteria for safety, earth resistance, grid resistance, maximum grid current, minimum conductor size and electrode size, maximum fault current level and resistivity of soil. Calculations of three separate earthing body earth, neutral earth and main earthing are described.
