PERFORMANCE OF LFAC TRANSMISSSION SYSTEMFOR TRANSIENTSTATE
No full textThis paper deals with thetransientperformance of a low-frequency ac (20Hz) transmission system for a wind rampevent. The LFAC system is interconnected with the 50Hz grid with a Cycloconverter. The wind power from the offshore is in the form of dc, and is interconnected to the LFAC transmission line with a twelve-pulse thyristor inverter. Thegraphs of transient response of proposed system parametersare plotted.The circuit model of LFAC system is simulated in MATLAB/SIMULINK
MATCH-MOBILE AUTO-INSURANCE CLAIM AND HELPSYSTEM
No full textThe project is about to develop a mobile application using the platform independent technologies. It supports all the types of platform like android, windows etc.When it comes to vehicle accidents, people are stressed out and overstrained, even if it is just a carbody damage and no one ishurt. They often lack adequate and immediate assistance and may worry about the lengthy and paper-based loss report to their insurance carrier. At the same time, it is crucial for insurance companies to receive early and detailed case circumstances in order to decrease costs and assist customers with value-added services.Weproposed tobuild a mobile application MATCH to meet the said objectives.MATCH will provide an easy mechanism to capture images of the damaged vehicle and immediately submit the first intimation report to the insurance company from a Smartphone. It will also display a map showing the nearby hospitals and towing assistance services along with their contact numbers.This application will be most useful in future to reducethe human effort and to claim using a single click from the application

A REVIEW ON “DESIGN OF CONNECTING ROD FOR WEIGHT REDUCTION USING ALTERNATIVE COMPOSITE MATERIAL”
No full textConnecting rods are the integral parts of an internal combustion engine. The efficiency of any engine can be defined as less the weight ofany engine lesser the energy required hence it is important to reduce the weight. There is a demand for high speed and efficient vehicle. For a high-speed vehicle, the manufacturer has to design lighter, faster, and more efficient engines. In this context, it has become important to optimize the design of Crankshaft assembly which is amongst larger volume production components in the internal combustion engine. Weight reduction of a connecting rod will increase the fuel efficiency of the engine. It is found from the literature that to satisfy the objective of weight reduction, the use of composite materials plays a vital role. Aluminum SiC fly ash composite can be used as an alternate material. It gives the required strength and lightweight. In the view, the project is undertaken to use the Aluminium SiC fly ash composite material for the design of connecting rod for weight reduction
THE INFLUENCE OF THE FAMILY ENVIRONMENT ON STUDENT LEARNING OUTCOMES IN IPS LESSON IN SDN 83 KOTA TENGAH KOTA GORONTALO
No full textPurpose this study was to determine how much influence the family environment has on student learning outcomes in social studies lessons at SDN 83 Kota Tengah Kota Gorontalo. The method used in this research is quantitative method with data collection through observation, questionnaires and documentation using simple regression data analysis. The results showed the students at SDN 83 Kota Tengah Kota Gorontalo, it was concluded that the family environment was one of the factors that had an influence on student learning outcomes. The influence of the contribution of 35.4% to the student learning outcomes variable, while the other 64.6% is influenced by other factors outside the variables studied. So the findings of this study are in accordance with the mindset put forward in the conceptual framework in which a good family environment tends to have a positive effect, so that children's learning outcomes are good. Conversely, if the family environment is not good, a large trend will have a negative impact on student developmen
EXPERIMENTAL STUDY OF HEAT TRANSFER FROM PLATE FIN ARRAY IN MIXED CONVECTION MODE
No full textThe work summarized in this paper presents an experimental study of heat transfer from plate fin in mixed convection mode enhancement by the use of plate fins is presented. After a brief review of the basic methods used to enhance the heat transfer by simultaneous increase of heat transfer surface area as well as the heat transfer coefficient, a simple experimental method to assess the heat transfer enhancement is presented. The method is demonstrated on plate fins as elements for the heat transfer enhancement, but it can in principle be applied also to other fin forms
DESIGN, ANALYSIS AND MANUFACTURING OF SPECIAL MANDREL FOR GEAR TEETH GRINDING
No full textIn the present techno economic scenarioevery manufacturing industry takes great effort in cutting down costs by reducingerrors in manufacturing and resources. Our present investigation is an attempt made in the same direction by designing a special mandrel which willeliminate run-out error of gear, reduce inventory costand increase productivity by reducingthe machiningtime.Geer teeth Grinding, as a final process,exerts great influence on quality and accuracy of surface layer of teeth of gears. The mandrel and sleeve is designedin suchawaythat it can accommodate a range of gear sizes on a single mandrel instead of using separate mandrel for each gear. For example: For gear sizes of internal diameter 31-40 mm only one mandrel is required along with expandable sleeves.As per the problemidentified we designed a mandrel and sleeve, in CATIA-V5. Further it was analysed in the software for any aberrations. It wasthensimulated for real time working conditions. After complete analysis and approval of design , all modes of failureswere tested and design was finalized and selected for fabrication
SEED SOWING MACHINE
No full textAgriculture is the backbone of Indian economy. About half of the total population of our country has chosen agriculture as their occupation. The states like Maharashtra, Punjab, Kerala are highly involved in agriculture. Hence the objective of our project is to develop a better Mechanical machine to help the agriculture field which reduces the amount of work and time spent on crop. Sowing machine which are suitable to all types of farms and corps. the equipment is robust in construction and also it is should be reliable which is basic requirement of Sowing machine. As there is a scope for developing the sowing machine and which is operated manually but reduces the efforts of farmers, thus increasing the efficiency of planting also reduces the problem encountered in manual planting. The application of this machine can be implemented for various plants and different sizes of seeds, also variations in the space between seeds while planting can be varied as per requirement. This also increases the plant efficiency and productivity. For effective handling of the machine by any farmer or by any untrained worker it has been simplified in design also its adjustments and maintenance methods are also simple
APPLICATION OF THE WAY MODELING METHOD TO IMPROVE STUDENTS 'SPEAKING SKILLS IN CLASS V SDN 4 BULANGO TIMUR
No full textThe problem studied in this research is "Can the application of the modeling method the Way improve the speaking skills of students in class V SDN 4 Bulango Timur?" The purpose of this study was to improve students' speaking skills through the application of the Modeling the Way method in class V SDN 4 Bulango Timur. The research method used is classroom action research (PTK). Data collection techniques through observation, tests, and documentation. In the initial observation, 7 students or 36% of the 19 students spoke fluently. In the first cycle after using The Way modeling method increased to 12 people or by (63%). In the second cycle, it increased again to 18 students or (94%) from 19 total students. Based on these results, it can be concluded that the Modeling the Way method can improve the speaking skills of students in class V SDN 4 Bulango Timur.
