Abstract: In line with technological developments, cell phones are not only used as a means of communication, but are also used for other activities. However, there is an indirect negative impact caused by the electromagnetic field radiation from this device. As well as disrupting the work system in the human body, including changes in heat energy in the tissues of the human body. Research on the effect of electromagnetic radiation on human body fluids has been carried out with simulations using replacement fluids at a frequency of 900 Mhz. Signal generators are used to simulate the emissivity of a cell phone with a transmit power of more than 3.4 times or 5.34 dB of the power emitted by a cell phone. The results of measurements and calculations in the study showed no significant effect on temperature increases or changes in body fluid color. The result of the calculation of the SAR (Specific Absorption Rate) value of the maximum emissivity signal produced is 109.46 dBµV - 0.3 V/m, for the conductivity and density of body fluids is 7.46 kg/m3, and shows that it is still below the threshold. the radiation limit permitted by the FCC is 1.6 W/kg, and ICNIRP 2.0 W/kg. It should be noted that the measurement results obtained are the results of measurements including environmental conditions where there is still wave interference from other sources (noise), as well as a relatively short measurement time.Abstract: In line with technological developments, cell phones are not only used as a means of communication, but are also used for other activities.

Abstract: This paper presents a practical application of Harvesting Ocean Power of Break Waves in the Indian ocean shores, conversion into Electrical Energy, and distribution to the Coastal States. The Indian peninsula has ten coastal states that can generate electricity from Wave Energy Converters (WEC). Unlike Western countries, off-shore WECs of each more than 500 kW are built-in Oscillating Water Column (OWC) of Floating Wind Power, Heavy Buoy Device, etc. We employ 30 to 35 numbers array of PM alternators of each 30 to 50 kW. They are positioned in a zigzag pattern at 100 to 150 meters long on the Shallow Water shore, where the Breaking Sea Waves evolve to give one MVA power or more. The generated power is brought to the shore stations for conditioning and converting to three-phase 440 Volts 50 Hz power for distributions. We have the potential to transform Break Wave Power of 40,000 MVA through the length of the Indian Ocean shore.Abstract: This paper presents a practical application of Harvesting Ocean Power of Break Waves in the Indian ocean shores, conversion into Electrical Energy, and distribution to the Coastal States.

Abstract: The low productivity experienced in our industries is as a result of not imbibing intelligence in its production mechanism. We know that induction motors are reliable, robust and with good operating characteristics. A means of starting, regulating and controlling operating parameters are very necessary to improve motor efficiency. This low productivity witnessed in our brewery industry is surmounted by modeling of alternating current (a.c) motor performance for increased production output using fuzzy logic controller. To achieve this it is done in this manner, characterizing and modeling a conventional AC motor so as to establish its operational features while working on variable frequency drive (VFD) control model with known production output, designing a rule base for the use of fuzzy controller for a stable and improved production output of AC motor and designing SIMULINK model for the performance of AC motor under operational condition for an increased output using fuzzy controller for a brewery industry. The results obtained are the highest conventional quantity of bottles of beer produced was 3240 while that of fuzzy controller was 3245 at a stable time of 4 through 10 seconds. With these results obtained, it shows there is an improvement in the production capacity in brewery industry when fuzzy controller is incorporated in the system.Abstract: The low productivity experienced in our industries is as a result of not imbibing intelligence in its production mechanism.

Abstract: IGCC power plant is the one in which coal is gasified and then the energy is used to drive both gas turbine and steam turbines to produce energy. As the industrial revolution is progressing more and more carbon dioxide is being added to the environment every single day which is leading the world towards the biggest environmental hazards we have ever faced, global warming being the leading consequence, so capturing the carbon dioxide which is emitted from sources like power plants is of the utmost importance. The main idea of this research paper is to provide an innovative way of capturing carbon dioxide emissions from a coal powered power plant. This research paper discusses the design and modeling of a carbon capturing membrane which is being used in an IGCC power plant to capture carbon dioxide from its exhaust gases. The modeling and design of the membrane is done using CFD software namely Ansys workbench. The design and modeling is done using two simulations, one describes the design and structure and the second one demonstrates the working mechanism of the membrane. This paper also briefly discusses IGCC which is environmentally benign compared to traditional pulverized coal-fired power plants, and economically feasible compared to the natural gas combine cycle (NGCC). IGCC power plant is more diverse and offers flexibility in fuel utility. This paper also incorporates a PFD of integrated gasification power plant with the carbon capturing membrane unit integrated in it.Abstract: IGCC power plant is the one in which coal is gasified and then the energy is used to drive both gas turbine and steam turbines to produce energy.
