Abstract:

In this research, wood ash collected from the uncontrolled burning of saw dust and examine for its suitability as a partial replacement of cement into normal concrete. Saw dust has been collected from a wood polishing unit. Chemical and physical properties of wood ash are presented. The mechanical parameters (Compressive Strength, Split tensile strength and Flexural strength) of concrete with blended wood ash cement are investigated and studied. Water to binder ratio 0.4 and seven different percentages of wood ash as partial replacements as been taken i.e., (0%, 2%, 4%, 6%, 8%, 10%, &12%). Results of compressive strength, split tensile strength and flexural strength showed that that strength parameter was increased at 4% partial replacement and decreased by increasing the wood ash. From this study concluded that wood ash can also used as partial replacement material.

Abstract:

Today’s Business scenery is influenced by Social media propagation. The companies need the information about the How, when and where the business to exit , where the customer exist and needs of the customer changes significantly because of implementation of social web. In relationship marketing previous studies proposes before going to purchase of any product customer will need the information the product will going to be right or wrong to him and to maintain the product for a long period through commitment and responsible and emotional bonding with the company. Therefore, the success of any marketing campaign is depending on trust, commitment, responsibility and bonding of the customer with the company. Indian Corporate has just begun to invest in Social media and are thinking of effective engagement strategies with their audience. The study revealed certain important implications for practicing managers.

Abstract:

The I-V characteristics of solar cell are affected due to solar irradiation and local temperature conditions. The solar cell array output power varies due to variations in radiation and cell temperature. Various maximum power point tracking (MPPT)algorithms are developed for extraction of maximum powerfrom a solar array when it operates at MPP which varies continuously whenever there is change in solar panels temperature or irradiance. The solar cell array is integrated with intermediate converter to utilize extracted maximum power from the solar panel. This integrated system operated at high efficiency and the low operating cost. This paper discusses about Perturb & observes algorithm implementation by considering only voltage profile of solar cell module. The integrated system comprising of solar array, boost converter along with MPPT is simulated using MATLAB/SIMULINK tool.

https://doi.org/10.26782/jmcms.spl.5/2020.01.00034

Abstract:

Voltage regulation is vital in DC microgrids and the power generated at DC Bus of DC Microgrid is fed to AC side via. Interlinking converter in an AC-DC microgrid. Many Droop control techniques are used to efficiently control the voltage regulation at DC bus and sharing load demand among DGs (distributed generators) as per their individual droop characteristics in a decentralized manner. Low rating hybrid residential microgrids are eventually increasing popularity which are to be controlled to inject power into grid in grid-tied mode and to meet power balance in Islanded modes. The Proposed Unified dp / dv control strategy for a Multi-port DCDC converter, not only improve transient performance of DC-DC converter in tracking MPP compared to other methods, but also improves DC bus voltage regulation and battery SOC control. This control eliminating the switching between MPPT and voltage regulation modes. This Multi input DC-DC converter fed by Solar PV wind Battery storage is feeding power to critical DC load and connected to AC side via. Interlinking converter. The proposed System is implemented in MATLAB/Simulink to verify the effectiveness of this control strategy.

Abstract:

The Electronic wastes are one of the major problems faced by the world due to its unregulated accumulation. The recycling and reusing are the effective ways to reduce the E-waste accumulation in the environment. The E-waste stream consists of Compact Discs /DVDs wastes. The polycarbonate is the main element used for the manufacturing of Compact Discs. Polycarbonate in landfills is definitely an environmental nightmare since it contains the Bisphenol-A which is a toxic material. So these wastes should be properly recycled and it can be used in polymer composites. Fiber-fortified polymeric composites have across the board applications including designing ideas, because of main properties of light mass, solidness and high quality weight proportion. While dealing with the polymer composites the reinforcement used is glass fiber due to its availability and cost effectiveness. The effect of addition of Compact Disc particles as filler in woven glass fiber-epoxy composites has been investigated. The hand lay-up and vacuum bag moulding processes are used for the preparation of the test specimens. The tensile and flexural strength was improved with the filling of Compact Disc particles in the woven glass fiber composites.
