Effect of Compaction Moisture Content on Strength Parameters of Unsaturated Clay using Triaxial Test


Soil compaction is a process of mechanical densification of soil by pressing the soil particles close to each other and removing the air between them. It is of utmost importance in the broad science of Geotechnical engineering playing a significant role in all types of Geotechnical investigations. The principle soil properties affected by compaction include the shearing resistance. The constitutive equations for volume change, shear strength and flow for unsaturated soil have been generally accepted in Geotechnical engineering Fredlund and Rahardjo, 1993a . The shear strength of an unsaturated clayey soil and soil water characteristic curve depend on the soil structure or the aggregation which in turn depends on the initial water content and the method of compaction. The aim of this research work is to determine the cohesion, angle of internal friction of the clay soil based on the moisture content. For this clay soils classified as CH, CI are used. Soil samples are chosen on the basis of soil type and clay content more than 25 . Maximum dry density and Optimum moisture content is are determined after 24 hour soaking, using light compaction. The hydrometer test are carried out for the grain size distribution. For the present work six different type of clayey soils are consider. The sample are taken from Dahej 02 , Surat 02 and Bhavnagar 01 . All the sample were tested at OMC and MDD as obtain from standard proctor test. The compaction was done at 0.95,1.00 and 1.05 times of OMC. Each sample were tested for triaxial test as well as direct shear at the strain rate of 0.625 mm min and 1.25 mm min. direct shear test and triaxial test are conducted for unconsolidated undrained UU condition.

Design and Fabrication of IoT Enabled Wheelchair cum Stretcher with Home Automation and Patient Monitoring System


The proposed project was aimed at designing and fabricating a wheelchair cum stretcher that can overcome the shortcomings of a conventional wheelchair, with focus on cost effectiveness and utility. This project will eliminate the use of a separate wheelchair and stretcher in hospitals. The proposed idea describes the wheelchair, which can transform itself into a semi chair and stretcher and the mobility of the wheelchair positions are made with the help of knob without any assistance. In addition to it, the proposed project has the IoT enabled home automation to control the household devices and patient monitoring system for regularly monitoring the health of patients at home.

Partial Replacement of Natural Sand by Microfines for Cement Concrete

The purpose of this study was to investigate the PARTIAL REPLACEMENT OF NATURAL SAND BY MICROFINES FOR CEMENT CONCRETE. The suitability of crushed stone dust waste as a fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Two basic mixes were chosen for natural sand to achieve M25 and M30 grade concrete. The equivalent mixes were obtained by replacing natural sand by stone dust partially and fully. The test results indicate the crushed stone dust waste can be used effectively to replace natural sand in concrete. In the experimental study of strength characteristics of concrete using crushed stone dust as fine aggregate it is found that there is increase in compressive strength, flexural strength and tensile strength of concrete.

Mechanical Energy Harvesting using Piezo Triboelectric Nanogenerator


As there is a rapid growth of portable electronic gadgets, sustainable energy sources for these devices become indispensable. The possibility to power them by energy harvested from renewable sources have to be found. Triboelectric nanogenerators are the most viable solution to harvest energy from low frequency mechanical motions. A TENG is an energy harvesting device that converts external mechanical energy into electricity by a conjunction of contact electrification and electrostatic induction and this electricity is used to power our electronic gadgets wirelessly by using wireless module and piezoelectric nanogenerators also do the same on applying the pressure. This device opens a new horizons for ways to produce and store wasted energy from our surroundings and in a near future to power wireless sensors and electronic gadgets using hybrid piezo triboelectric nanogenerators.

An Automatic Load Controller for Domestic Applications

This paper presents a system to avoid the procedure of load shedding. Here the relation with frequency and power is utilized. A system of automatic controlling of devices which will help us to save the power to a greater extend is proposed here. For each device connected to the system, a cutoff frequency is fixed. When the frequency of the power supply goes below this cutoff frequency, the particular device will be automatically turned off and the device will return to its normal operating condition when the frequency reaches its normal value.

Assessment for Water Quality of Mutha River using Correlation


 river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea. Mula Mutha river is one of the major river of Pune city. Mula originates from Mulshi dam and it passes through Poud, Lavasa, Wakad, Balewadi, Baner, Aundh, Khadki, Vishrantwadi, and ends at Sangamwadi. Monitoring of river involves comparison of water quality data between stations, analysis of water quality trends, development of cause effect relationships between water quality data and environmental data. Present work deals with the analysis of physico chemical parameters of Mutha river i.e from Khadakwasla Dam to Sangam Bridge. Water samples are collected from four locations. Water quality assessment is carried out by "correlation coefficient r "is determined using "correlation matrix" to identify the highly correlated and interrelated water quality parameters. The study involves certain physico chemical parameters such as dam pH, Turbidity, Electrical Conductivity, Hardness, Alkalinity, BOD, COD, TDS and correlation between them.

Power Quality Improvement using Shunt Active Power Filter with PI and PID Controller

Problems caused by power quality have great adverse economical impact on the utilities and customers. Current harmonics are one of the most common power quality problems and are usually resolved by the use of shunt passive or active lters. In this paper we have compared the THD values of Shunt active power filter with PI and PID controller application for a given model. The design concept of the adaptive shunt active lter is veri ed through simulation studies and the results obtained are discussed. THD is most suitable to control the shunt active power filter in term of total harmonic reduction THD . MATLAB SIMULINK power system toolbox is used to simulate the proposed system.
