Every H-bridge module is associated with a 185-W ssolar panel. Simulation results are exhibited to confirm the achievability of the proposed approach in MATLAB/SIMULINK environment
An Explorative Study On Quarry Dust Blended Geo Polymer Concrete For Various Concentrations Of Alkaline Activated Solution
Get PDFConcrete is the most widely used construction material in the world and Ordinary Portland Cement (OPC) is the major ingredient used in concrete. The production of cement releases large amount of carbon dioxide (CO2) to the atmosphere that significantly contributes to greenhouse gas emissions. It is estimated that one ton of CO2 is released into the atmosphere for every ton of OPC produced. This project mainly aims at the study of effect of concentration of alkaline activated solution on the properties of geo polymer concrete (GPC) with the replacement of fine aggregate with quarry dust using sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) solutions as alkaline activator. The replacement of sand with quarry dust in GPC mix enhanced the mechanical properties at ambient room temperature curing at all ages. The Geo-polymers are comprised of alumina-silicate materials which completely replaces the Portland cement in concrete. The alumina-silicate materials which are dissolved in alkaline activated solution i.e., Sodium Hydroxide or Potassium Hydroxide which subsequently polymerizes into molecular chains and networks to create the hardened binder which are referred as inorganic polymer cements. The main objective of this project is to investigate the compressive strengths for various concentrations of alkaline activated solution with the replacement of river sand by quarry dust. The Mix design procedure is examined with M-20 grade of geo polymer concrete. The compressive strength and workability of the concrete are studied for various grades of the Geo-polymer concrete
IoT Based Smart Trash /Garbage Collection System
Get PDFWaste Management is one of the major problem in our day to day life. The current observation is that trash-bin is not efficiently managed, it is not emptied from time to time thus leading to a critical situation which has many adverse effect on the environment and the surrounding inhabitants. Thus waste should be managed efficiently right from the time to time collection of the waste of particular areas and then treatment should be done. Hence, we are making this in real time scenario by connecting to the Internet of Things (IoT) concept. To overcome the problems caused by the waste disposal we can use the concept of smart-trash bins. The system makes use of MSP 430 microcontroller, LCD screen, Wi-Fi module for sending bin status data. The LCD screen is worn to exhibit the status of the level of refuse together in the bins. Whereas a web page is built to show the status to the municipal right or user to monitor it. The web page offers a graphical vision of the garbage bins and things to see the garbage collectively. It also analyses the received data and represents each city bin status for a particular time period in graphical manner, such that they can analyze the cleanliness in the city
A Novel Control Scheme for a Stand-Alone Wind Energy Conversion System
Get PDFThis work presents control plot for a remain solitary wind vitality change framework. Vitality is the thought to be the essential contribution for improvement. At present attributable to the exhaustion of accessible ordinary assets and concern with respect to natural corruption, the sustainable sources are being used to meet the steadily expanding vitality request. Because of a moderately minimal effort of power creation wind vitality is thought to be one of the potential wellsprings of clean vitality for what's to come. In any case, the nature of wind stream is stochastic. So thorough testing is to be completed in research facility to create effective control methodology for wind vitality change framework (WECS). The investigation of WECS and the related controllers are, in this way, ending up noticeably more huge with each passing day. Display vitality require intensely depends on the customary sources. In any case, the restricted accessibility and consistent increment in the cost of regular sources has moved the concentration toward sustainable wellsprings of vitality. Of the accessible option wellsprings of vitality, wind vitality is thought to be one of the demonstrated advancements. With a focused cost for power era, wind vitality transformation framework (WECS) is these days sent for meeting both matrix associated and remain solitary load requests. In any case, twist stream by nature is discontinuous. So as to guarantee consistent supply of energy appropriate stockpiling innovation is utilized as reinforcement. In this venture, the supportability of a 4-kW half breed of wind and battery framework is explored for meeting the necessities of a 3-kW remain solitary dc stack speaking to a base telecom station. A charge controller for battery bank in light of turbine greatest power point following and battery condition of charge is produced to guarantee controlled charging and releasing of battery. The mechanical security of the WECS is guaranteed by methods for pitch control procedure. Both the control plans are incorporated and the adequacy is approved by testing it with different load and twist profiles in MATLAB/SIMULINK
Efficient User Revocation Technique for Data Forwarding In Untrusted Cloud
Get PDFWe propose a safe information sharing plan for dynamic individuals. Initially, we propose a secured way for key transport with no sheltered correspondence channels, and the customers can securely get their private keys from get-together chief. Second, our arrangement can finish fine-grained get the chance to control, any customer in the social affair can use the source in the cloud and denied customers can't get to the cloud again after they are disavowed. Third, we can shield the arrangement from connivance strike, which suggests that revoked customers can't get the primary data report paying little mind to the likelihood that they plot with the untrusted cloud. In our approach, by using polynomial limit, we can fulfil a protected customer denial plot. Finally, our arrangement can achieve fine capability
