Inductor coupled converter

This research work presents a high gain direct current–direct current (DC–DC) converter which is derived from a traditional boost converter. Distributed renewable energy sources such as photovoltaic (PV) modules, wind, and fuel cells are becoming possible alternatives. However, to connect these systems to the grid, reliable DC–DC boost converters with high voltage gain is becoming a requirement. Firstly, a new open-loop DC–DC boost converter with superior performance in terms of voltage step-up ratio and reduced voltage stress on the switches, compared to other existing high gain DC–DC boost converter counterparts is proposed. Along with analyzing the operation principle of the proposed converter. This converter can easily achieve a gain of 20 while benefiting from the continuous input current, effectively maintain the voltage output at the required level, closed loop dc-dc converter with Proportional–Integral-Differential (PID) controller, a multi-loop with Proportional–Integral (PI) was proposed and simulated. a charge controller was designed and operated along with closed loop dc-dc converter to supply load with two different voltage requirements. Based on the simulation results the proposed controller can maintain the output voltage at the required level with respect to the changes in load.

COVID-19 facemask and Social Distancing Detector

The world is facing a huge health crisis due to the rapid transmission of COVID-19. The World Health Organization (WHO) issued several guidelines for protection against the spread of coronavirus. The impact of COVID-19 has fallen on almost all sectors of development, mainly the healthcare system is going through a crisis. According to WHO, the most effective preventive measure against COVID-19 is wearing a mask and maintaining social distance in public places. This paper introduces face masks and social distancing detectors that can be used by the authorities to make mitigation, evaluation, prevention, and action planning against COVID-19 which is causing a health crisis. Detection of people who are not wearing masks and not maintaining social distance is a challenge due to the Outbreak of the Coronavirus pandemic which has created various problems. This paper aims at explaining the design of a system that helps in solving the above issues, i.e detection of mask and social distance.

Review on Improving the capacity of black cotton soil by using different materials example bio-enzymes and bagasse ash, etc.

Soil is the main part of the foundation; it is very important to build a strong and durable structure. If soil is not stable then, there may cause the failure of the structure. In black cotton, the soil has a very low bearing capacity and high swelling and shrinkage characteristics it forms a very poor foundation, that cannot be affordable, India is the largest area occupied by black cotton soil. India is an agricultural country that comes in the top ten countries in the world it contributes many times through the agricultural field. India consists of 30-40% of Black cotton soil. Maharashtrian Western produces sugarcane on a large scale and bagasse formed by sugarcane. And to improve the strength of soil the stabilization (making more stable) of soil by conducting experiments on Black cotton soil by replacing bagasse ash (4%, 8%,12%,16%,20%). Another material mixed in black cotton soil is bio-enzyme (Terrazyme) with different dosages of 250ml/2m^3,250ml/1.5m^3,250ml/1m^3,250ml/0.5m^3 respectively. Due to this the strength of soil increases.

The efficiency of food waste material for the removal of metal and metalloid from a multi-element solution

Excessive release of wastewater particularly rich in heavy metals from industrial activities is a critical environmental problem worldwide. Many metals, which are toxic and can cause various environmental problems Therefore, their removal from polluted solutions becomes one of the focuses of environmental remediation. The studies have shown the potential of food waste materials as low cost adsorbents for the removal of heavy metals and toxic elements from wastewater. Adsorption processes are being widely used by various researchers for the removal of heavy metals from waste streams and activated carbon has been frequently used as an adsorbent. Despite its extensive use in water and wastewater treatment industries, activated carbon remains an expensive material. In this study, the adsorption capacities of food waste materials along with agricultural and industrial waste by-products such as rice husk and fly ash were evaluated by comparing the adsorbents’ efficiency for the removal of elements from complex element solutions, maintaining homogeneous experimental conditions. The examined materials resulted to be extremely efficient for the adsorption of many elements from multi-element solutions as well as from a heavy metal wastewater. The objective of this research is to study the utilization possibilities of less expensive adsorbents for the elimination of heavy metals from wastewater.

Management of fractured endodontic instruments by file bypass technique: A report of two cases

The separation of an endodontic instrument within the root canal system can be one of the most stressful and unpleasant situations with which the clinician can be confronted. These fractures often occur due to incorrect use of instruments. Different devices and techniques have been developed to retrieve fractured instruments during the endodontic procedures The clinician is confronted with a few options when considering this situation. These options can include leaving the fragment where the fracture occurred and incorporating the fragment to form part of the final obturation or removal from the root canal. It can be stated that the bypass technique can be considered a simple and effective technique for the management of broken instruments into the root canal.

Advance skin diseases diagnosis and leaveraging using image processing

Air pollution has a variety of effects on human skin. In heavily populated areas, skin problems are very frequent. These diseases have a severe effect on people's life because they create a significant demand for disease diagnosis. The suggested study on a skin disease detection system uses image processing to get an accurate diagnosis. By studying the input image, the process detailed here seeks to discover skin illness. Filtering the input to eliminate noise, converting the image to a grayscale image, and image segmentation are all part of the approach. Feature extraction is used to reduce the quantity of data that the classifier has to process. The SVM (Support Vector Machine) is then used in the image classification to identify the skin disease. The greater use of technology has resulted in a more efficient and accurate manner of diagnosing the disease, allowing it to be treated more quickly. Skin illnesses such as rosacea, melanoma, psoriasis, and acne can be detected with an accuracy of 89 percent using the proposed method.
