Speed Controlling Of Three-Phase Induction MotorUsing VFD
Published Date - 23 Apr
This paper explains how Variable Frequency Drives (VFDs) work and talks about their performance. It also discusses a simulation model made using MATLAB Simulink and analyzes the results. It looks at something called Total Harmonic Distortion (THD) in waveforms. VFDs are being used more and more in heating, ventilation, and air conditioning (HVAC) systems, like air handlers, chillers, pumps, and tower fans. Understanding VFDs better can help choose and use HVAC equipment and systems more effectively. This paper aims to explain VFD terms, how they work, how they improve Power Factor, how they deal with Harmonics, and includes a simulation project showing how VFDs can save energy. It also compares VFDs with other technologies according to industrial standards.
Design, simulation and installation of 100kwp bifacial solar panels at Nyabira Solar Farm, Zimbabwe for backup power in Harare's manufacturing industries
Published Date - 23 Apr
Renewable energy has come to light as a crucial way to reduce carbon emissions and move toward a more sustainable energy future as the world struggles with the effects of climate change. In this context, the use of solar photovoltaic (PV) systems has become increasingly popular because of its cost-effectiveness, environmental friendliness, and technological innovation. In order to provide backup power for the industrial businesses in Harare, Zimbabwe, this thesis focuses on the design, simulation using PVsyst and PVSOL simulation softwares and installation of 230 modules of bifacial solar panels at Nyabira Solar Farm on a model plane open area of 0.4km as to give out a annual energy generation of 182885 kWh which on ground becomes a successful project when we install the panels at an free open space of 60km .Furthermore a comprehensive financial analysis shows a total installation of USD100000 which includes the prices of the inputs which are bifacial solar panel, inverters and the labour cost.
This study offers a thorough analysis of the different control systems and techniques used in structural engineering, emphasizing the mitigation of dynamic actions like severe winds and earthquakes. The study explores the implementation of active, semi-active, and hybrid control systems in civil engineering structures to enhance their resilience against dynamic forces. Traditional approaches to reducing vibrations, such as building structures with resistance and ductility, are compared with newer concepts of structural control. The paper discusses the development and application of passive, active, hybrid, and semi-active control systems, highlighting their advantages, limitations, and real-world implementations. Furthermore, it explores recent advancements in smart structures and control technologies, including the usage of magnetorheological (MR) dampers, piezoelectric actuators, and fuzzy supervisory control approaches. Experimental validations and numerical simulations are employed to assess the efficiency and performance of these control strategies. Overall, the paper contributes to the understanding of structural control methodologies and their implications for enhancing the safety and resilience of civil engineering structures against dynamic forces.

They control all the plunging and pivoting activities. The warming, supported by DS18B20 temperature sensor, which is straightforward and reasonable, further develops conditions for covering. A 20x4 LCD front board fills in as a 0UI, and illuminates’ clients on the inside condition like the temperature, speed, and goal, in this way, providing the clients with some degree of control on the cycle. DipMatic puts extraordinary accentuation on its reasonableness and simultaneously it doesn't think twice about exactness. DipMatic pursues an incredible decision for changed ventures and applications consequently separating itself.
Review on Recycling of E-Waste with different fibre in concrete Technology
Published Date - 22 Apr
The world is emerging towards the online resources due to Covid-19. It is resulting into large use of electronic and computer devices worldwide. As new upgradation in E-devices is taking place, the old once again creating big problem for ecology and environment on earth surface. And to balance the E-waste produce and avoid the e-waste landfill all over the world. Hence vigorous and determinant attempts are made to use non-biodegradable E-Waste in concrete. The main intention is to add non-biodegradable E-Waste as fibers in concrete to upsurge the mechanical properties of concrete
