 Abstract

In the present society learning became complex with divergent resources of teaching and learning. Teaching even if restricted to four walls the present-day classroom teaching happens through video conferences, online interactions, social networks, learning apps and so on. Edmodo provides an interactive platform and also a web 2.0 tool for effective virtual classroom learning and global interaction. The present study aims to find out the perceptions of use of Edmodo as Learning Tool by pupil-teacher of different universities of Lucknow. The findings also reflects that there is difference in perceptions of pupil-teacher at university level.

 Abstract

Employing large intelligent surfaces (LISs) is a promising solution for improving the coverage and rate of future wireless systems. These surfaces comprise massive numbers of nearly-passive elements that interact with the incident signals, for example by reflecting them, in a smart way that improves the wireless system performance. Prior work focused on the design of the LIS reflection matrices assuming full channel knowledge. Estimating these channels at the LIS, however, is a key challenging problem. With the massive number of LIS elements, channel estimation or reflection beam training will be associated with (i) huge training overhead if all the LIS elements are passive (not connected to a baseband) or with (ii) prohibitive hardware complexity and power consumption if all the elements are connected to the baseband through a fully-digital or hybrid analog/digital architecture. First, a novel LIS architecture based on sparse channel sensors is proposed. In this architecture, all the LIS elements are passive except for a few elements that are active (connected to the baseband). We then develop two solutions that design the LIS reflection matrices with negligible training overhead. In the first approach, we leverage compressive sensing tools to construct the channels at all the LIS elements from the channels seen only at the active elements. In the second approach, we develop a deep-learning based solution where the LIS learns how to interact with the incident signal given the channels at the active elements, which represent the state of the environment and transmitter/receiver locations. We show that the achievable rates of the proposed solutions approach the upper bound, which assumes perfect channel knowledge, with negligible training overhead and with only a few active elements, making them promising for future LIS systems.

 Abstract

According to the studies conducted by the University of Chicago's Energy Policy Institute, urbanization is a major cause of air pollution, but it is inevitable. This study aims to determine the impact of air quality on land conversion in urban areas and propose a solution for enhancing the quality of air. This study examined variations in air quality resulting from different land use patterns in Bengaluru, including residential areas, forest areas, wide-open spaces, farmland, barren layouts, and plotted layouts that had vegetation. To calculate the air quality index, particle matter, PM2.5, and PM10 were measured using a Plat tower PMS5003 air quality sensor. The plotted layout with vegetation is considered the center, around the radius of 500m to 2000m surroundings with different land-use areas AQI was measured. The values are plotted and analysed. In comparison to other populated areas, the plotted layout with vegetation shows a better AQI. For the betterment of AQI, we need to design a layout in such a way that the planted trees in the layout will absorb the maximum possible PM particles from polluted air. Our proposal says that choosing trees for the layouts and planting them in the right place helps to improve the air quality index.

 Abstract

A. Cam is a mechanical device used to transmit motion to a follower by direct contact. The driver is called the cam and the driven member is called the follower. In a cam follower pair, the cam normally rotates while follower may translate or oscillate. The cam is a rotating part that provides reciprocating or oscillating motion to the follower by direct contact. Jumping happens when cam rotates at critical speed above certain value. At jumping, the speed is so high that the follower does not follow the cam and we get a sound of different type. The Cam-Follower material should have good thermal conductivity, thermal resistance and withstand high contact pressures. Friction composites mainly consist of about ten classes of ingredients such as, binder, fibres, friction modifiers and fillers. The proper selection of cam profile is the most important aspect in a diesel engine, as it determines the magnitude of valve lift. Hence in this case study, the cam follower material of Grey Cast Iron is tested with Stainless steel and Al2014. The main objective of the research is to find the alternative material for Grey cast iron so as to reduce the weight and maintain the strength. Hence wear analysis is done on Tribometer for wear rate and wear volume analysis.

 Abstract

With the growing demand for renewable energy, the demand for PV electricity has expanded even more due to its abundant supply and ease of control. The most critical factor in PV system design is effective solar energy conversion and cost reduction. A photovoltaic system is proposed to be modelled and simulated in this work. The effect of temperature on the power is studied in this paper and for this different temperature were studied The proposed work also perform an analysis using Ansys workbench to check the thermal properties of material used for PV cell in order to make the solar PV cell design optimized. This work examines the impact of temperature on the maximum power thus the proposed model performs analysis for different temperature to evaluate the maximum power generated by the system.

 Abstract

Floods is the most common natural disaster which occur when excess of water flow onto the land and that can have living life and stability losses Some reason are responsible to cause flooding For e.g. rapid snowmelt, blockage of the drainage system, high rainfall, insufficient water pump capacity in flood prone areas, improper environmental damage . there are different type of flooding. they are such as Storm Surge, Coastal Flood, River Flood etc. The aim of this paper to find out flood prediction using Artificial Neural Network. The aim of this project is to monitor real time the flood data and alert notification if there is an occurrence of risk through IOT. The rising water level is use to detect the floods . The system uses different sensors to detect maximum water reach point, storage of tank, rain fall sensor and measure the value at every stage. The sensor senses the data and processed to microcontroller and is transmitted to internet through wi-fi Module. The system sends data to Mysql database and applies Artificial Neural Network algorithm to perform Classification process. The experimental results show real time data that might be useful to prevent from flood. Artificial Neural Network give us Training data accuracy and validation data accuracy, training data loss and validation data loss respectively.
