 Abstract

Wind energy has become a second dominating source in the world renewable energy generation. Conversion and distribution of the wind energy have brought technology revolution by developing advanced wind energy conversion system (WECS) including multilevel inverters (MLI). The conventional rectifier produces ripples in their output waveforms while MLI suffers from voltage balancing issue across dc-link capacitor. This paper proposes a simplified proportional integral derivative (PID)-based space vector pulse width modulation (SVPWM) to minimize the output waveform ripples, resolve the voltage balancing issue and produce betterquality output waveforms. On the other hand, WECS experiences various types of faults particularly in the dc-link capacitor and switching devices of the power converter. These faults, if not detected and rectified at early stages, they may lead to catastrophic failures to the WECS and continuity of power supply. This paper proposes a new algorithm embedded into the proposed PID-based SVPWM controller to identify the fault location in the power converter in real time. Since most wind power plants are located in remote areas or offshore, WECS condition monitoring needs to be developed over the internet of things (IoT) to ensure system reliability. In this paper, an industrial IoT algorithm with associated hardware prototype is proposed to monitor the condition of WECS in real-time environment.

 Abstract

The COVID-19 pandemic has a huge impact on the population with consequences on lifestyles. The aim of the study was to analyse the Impact of Stress, Diet & Physical Activity on Menstrual Cycle during Pandemic Period. A survey was conducted online and offline mode during. Selected population was female young college students with the age range of 18- 26 years, compare them with their usual diet and emotional mood and identify variables that may have influenced changes. Data was collected among 187 adults from Palakkad (selected districts in Kerala) and Coimbatore district in Tamilnadu. The results show that COVID-19 confinement did influence their dietary habits and emotional level and menstrual pattern.

Nowadays there is a rapid increase in the usage of moblies for either voice calls or for the browsing or for watching HD videos online. There is a huge traffic in the usage of frequency band of present technology that is 4G technology. So to overcome this problem so many scientists did research and came up with a solution that to upgrade to 5G technology.5G technology is very fast and has higher bandwidth with higher datarate which is used to over come the problems caused due to higher traffic in the network. One of the important device in the 5G technology is antenna. In this paper, we are going to present the design and Time domain Analysis for Dipole Patch array antenna. The Antenna is made with Rodgers substrate of Di-electric constant which has High Dielectric Strength ?=3.55 to operate at millimeter wave frequencies and is designed to have Compact size, and model. The antenna is taken care of by Co-planar Waveguide Transmission line and has a smaller absolute size.

 Abstract

In recent years, every shopping place focuses on customer relationship management(CRM) to provide better services to the customer as compared to their competitors. To maintain a better relationship with the customer and helps to increase profit and satisfaction. It is important for marketers to identify the potential customers in the market by getting the customer data to gain profitable insight. It is the best way to find the appropriate customer segmentation by using clustering algorithms. The possibility of a hybrid combination of clustering algorithms like k-means and agglomerative individual models has also been discussed.

 Abstract

Media act as a mirror to the society as it keeps track to all the crucial information of the society and deliver that to the public through its various mediums like print, radio, TV, and digital. Media serves as a platform to different groups in the society, and it aware the people about the current happenings. Media becomes as important as our daily needs; it shapes the public opinion and strengthen the society. Today, the media is omnipresent and it caters the need of people. The research study, aims at analysing the impact of media and its effect on society. And this will help in studying the role of media in informing and educating the people about the current events of society. Its main focus is on how frequently people use media and effectiveness of media on social issues. The research study was conducted through secondary data.

 Abstract

The main objective of any company is to generate income, increase sales revenue, analyse the preferences and preferences of customers, meet the requirements and develop the business. To achieve this, you need to attract customers by offering more discounts and quality offers. The retail industry is evolving in India and there is a big change in people's sudden buying behaviour at Big Bazaar stores. It is important for vendors to understand this relationship. The retail sector is a permanent ever green business segment in the Indian market, and every retail company in the market is fighting on its own. To keep the minds of customers and to keep customers for a long time. The current retail sector is moving rapidly towards the next sector. In India, the Big Bazaar has an advantage. Encourage customers to buy products without specific lists through promotions, offers, exhibitions, window shopping and more. Discounts, coupons, combo, truth, low cost customers can buy products without special lists.

The field of Green Chemistry had been inconceivable used towards detections and recognitions in science & technology by smearing twelve basic green chemistry ideologies. , we explained the attainments and developments of green chemistry by using Green Empathies. Each branch of Green Chemistry tree represents to corresponding each of the 12 ideologies, and plants represent the different areas of achievement relevant to that particular ideologies.

 Abstract

This study was undertaken to understand the effects of glass fibre on concrete. Glass fibres are available readily in market at cheaper cost. Glass fibre was used as an admixture to test its effects on concrete. Glass fibre reinforced concrete can be used to increase the strength of concrete thereby improving the life of structure. In this study various percentage of glass fibres were added in concrete and the results were compared with Plain Cement Concrete to understand the Effects of glass fibre on concrete. Concrete beams were casted and allowed to cure for 28 days. The result showed that addition of 1% of glass fire increased the flexural strength of concrete, there were minimal or no changes noted in workability of concrete. On further addition of 2% of glass fibre, although the strength of concrete increased significantly but the workability of concrete decreased. It became very difficult to handle thee concrete and carry out tamping process.
