 Abstract

This present paper deals with the concrete mix of M25 grade which was made using OPC 53 grade of cement and in which rubber particles, recycled aggregates and steel fibers are used to replacing the cement, natural coarse aggregates and natural fine aggregates. Rubber particles in structural concrete is a sustainable solution to dealing with solid waste. This technology reduces the serious impact on ecological environments caused by a shortage of natural mineral resources. The aim of the present study is to investigate the coupling effects of incorporating rubber particles on the compressive and split tensile performances of selected M25 grade concrete. Casting of Cubes and Cylindrical Specimens of (150*150 mm) and (150 mm diameter and 300 mm Height) in Sizes to find out the fresh and hardened properties of M25 grade concrete mix for 7 and 28 days.

 Abstract

Falls have serious consequences and are prevalent in acute hospitals and nursing homes caring for older people Fall lead to many adverse consequences for the patients apart from physical injuries such as anxiety, depression and loss of independence. Technological interventions to reduce the risk of falling aim to monitor automatically monitor bed-exit events and subsequently alert healthcare personnel to provide timely supervisions. In that sense, the present work proposes an innovative IoT-based system for detecting falls of elderly people in indoor environments, which takes advantages of low-power wireless sensor networks and smart devices. For this purpose, we recognize the potential to employ a low resolution acceleration sensing modality in contrast to powering and sensing with a conventional MEMS (Micro Electro Mechanical System) accelerometer. A 3D-axis passive accelerometer with gyroscope embedded into a wearable sensor device is used, which is responsible for collecting data from movements of elderly people in real-time. The accelerometer data from the devices are continuously sent to a multithreaded server which hosts a pre- trained machine learning model that analyzes the data to determine whether a fall has occurred or not. Finally this system provides service built on cloud. If a fall is detected, an alert is activated and the system reacts automatically by sending notifications to the groups responsible for the care of the elderly people.

Abstract� The whole world is focusing on the utilization of renewable energy sources in order to mitigate the world power crisis. Power electronics is being used in a large scale for the renewable energy conversion in a more efficient manner. It has a great impact on controlling as well as interfacing the renewable system with both the grid and standalone applications. Hence more and more emphasis is given on design and control of power converters. In this paper different renewable energy systems (wind, solar) with different aspects of their power conversion have been discussed. Some basic principles of their operations with their recent technology advancements are reviewed. It is the reality that power electronics plays a vital part on interfacing and hence increasing the overall performance.

 Abstract

The present study was conducted to see the effect of cow urine on fertility levels and cow urine spray on growth and yield of Wheat (Triticum aestivum). Wheat (Triticum aestivum) is one of the important crop in the whole world and is consumed by nearly 65% of the Indian population. Among different organic sources cow urine is very unique product obtained from dairy and it has a high potential to prove as a organic fertilizer ,antimicrobial agent and disinfectant.The cow urine has proved to be a boon in the areas of agriculture, science and technology, industry, energy, medicine etc. for the development of any nation, there is a need in addition being eco-friendly in nature. Cow urine contains 95% water, 2.5% mineral salts and enzymes and remaining 2.5% contains the urea.In organic farming cow urine is used for enhancing the fertility level of plant and also the soil fertility. The nutritional effect of cow urine on plant growth was also tested with Wheat (Triticum aestivum) plant and protein and chlorophyll content was also estimated.

This paper reviews the power electronic applications for wind energy systems. Various wind turbine systems with differ- ent generators and power electronic converters are described, and different technical features are compared. The electrical topolo- gies of wind farms with different wind turbines are summarized and the possible uses of power electronic converters with wind farms are shown. Finally, the possible methods of using the power electronic technology for improving wind turbine performance in power systems to meet the main grid connection requirements are discussed.

 Abstract

The flat plate slab is gaining popularity among architects. The flat plate slab provides a way for architect to achieve completely flat ceiling with no beam protrusion. There is also improvement in the construction speed and cost savings from using this system which requires only simple formwork. But when load acting on the slab is large or clear span between columns is more so it is required to increase the slab thickness; hence the self-weight of slab is increased due to increased volume of slab and also more amount of steel is required to resist this increased weight of slab. 2This paper deals with voided slabs using U-boot beton technology made by recycled polypropylene. The technology is designs for light weight slabs in RCC. It is solution to build slabs of large spans with more bearing capacity.

 Abstract

The steady increase in population and overcrowding has become an unavoidable factor in any public gathering or on the street during any festive occasions. The development in technology has made monitoring smart and methods of tracking humans has advanced. In order to provide an aid to this problem, our project is proposing to provide technical support to manage the crowd by detecting humans and keeping in track the count of the people in the scene. In our study, we develop a system using Raspberry Pi 3 board that consists of ARMv8 CPU that detects the human heads and provide a count of humans in the region using OpenCV-Python. A Haar cascade classifier is trained for human head detection. Human tracking is achieved by indicating the direction of movement of the person. The results of the analysis will be helpful in managing the crowd in any area with high density of crowds.

 Abstract

Current Cloud Computing is primarily based on proprietary data centres, where hundreds of thousands of dedicated servers are setup to host the cloud services. In addition to the huge number of dedicated servers deployed in data centres, there are billions of underutilized Personal Computers (PCs), usually used only for a few hours per day, owned by individuals and organizations worldwide. The vast untapped compute and storage capacities of the under- utilized PCs can be consolidated as alternative cloud fabrics to provision broad cloud services, primarily infrastructure as a service. This approach, thus referred to as �no data centre� approach, complements the data centre based cloud provision model. In this paper, we discuss our opportunistic Cloud Computing system, called ADK that runs on scavenged resources of underutilized PCs within an organization/community- namely our college. Our system tries to identify that the �no data centre� solution indeed works.

 Abstract

In this study, work has been carried out to investigate tensile, hardness and impact properties of composite of material constitutes sugarcane bagasse powder and epoxy resin. These composite are adhered using epoxy resin HY951 resin and LY551 hardener suitably mixed in appropriate volume. Hybrid composites were prepared using sugarcane bagasse powder, while overall powder weight fraction was fixed as 20gram. Here for preparing samples Hand layup method is used, specimens are prepared. This constitute have good tensile & bending strength & their density. These composites can be used in various purposes because of its unique features of waste utilization, environment friendly, bio-degradability, good strength and a good alternative to plastics.
