Experiential Investigation on the Stabilization of Dispersive Soil with Lime

The soils that are highly susceptible to erosion and containing high percentage of exchangeable sodium ions are called Dispersive Soils. In appearance, dispersive clays are like normal clays that are stable and somewhat resistant to erosion, but in reality they can be highly erosive and subject to severe damage or failure. Using dispersive clay soils in hydraulic structures, embankment dams, or other structures such as roadway, embankments can cause serious engineering problems if these soils are not stabilized and used appropriately. This problem is worldwide, and structural failures attributed to dispersive soils have occurred in many countries. This paper presents the stabilization of dispersive soil with lime. The soil sample is taken from Mandalay. Grain size distribution, Atterberg's limit test, compaction test, unconfined compressive strength UCS test and triaxial test are carried out to obtain the properties of soil. Type of studied soil classified by unified classification system is lean clay with sand. Crumb test is performed to know the dispersion degree of study soil. According to crumb test, the study soil is highly dispersive clay soil. Lime is used as stabilizing agent. The amount of lime used is 2, 3 and 4 by dry weight of soil. The studied soil is mixed various contents of lime, and then crumb test is performed. At dispersive soil mixed with 4 of lime, there is no dispersion characteristic in soil. For stabilization of studied soil, 4 of lime is selected to investigate the improvement of strength in treated soil. The treated soil is performed compaction test, unconfined compression strength UCS test and triaxial test. Unconfined compression strength of treated soil at 4 lime is increased as 1.12 times that of natural soil. The shear strength of treated soil increases about 2 times than that of natural soil. The cohesion value of treated soil increases about 1.12 times and the angle of internal friction increases about 1.23 times than that of natural soil. Finally, it is concluded from this study that the lime treated soil is more resistant to erosion and the treated soil is more resistant to shear stress and lateral pressure.

Design and Implementation of Alcohol Detector and Accident Detection System using GSM Modem

Nowadays, the number of vehicles is increasing significantly every year. Many accidents are occurring because of the alcohol consumption of the driver. After drinking alcohol, driving is the most reason for accidents in almost all countries all over the world. Therefore, alcohol detection system and automatic finding car accident place using GSM modem and GPS are presented in this paper. The combination purpose of alcohol detection and car accident detection systems is to save human life. If the car driver drinks alcohol, the alcohol sensor will sense alcohol concentration, will display it on the LCD and will turn off the car engine. In the accident detection system, the vibration sensor senses vibration when an accident occurs. If the sensor senses the car accident, the vibration sensor will give the digital output to the microcontroller. By using the GPS module, the latitude and longitude of the place where the accident happened are sent by message to the assigned phone number through the SIM900 GSM Modem. By implementation of this system, human beings can be protected from harm and other non desirable outcomes on road accidents.

Performance Analysis of FIR Filter using FDATool

The performance analysis of the FIR filter is presented by testing with different windowing methods. The FIR low pass filter was designed with the windowing system. It was simulated by setting different orders for comparing the performances of the filter. And then, it was also tested with different windowing methods. The performances of FIR low pass filter are analyzed by setting various order numbers such as 10, 20, 50 and 100. These identified FIR filters are designed with four windowing methods. They are Kaiser Window, Hamming Window, Blackman Window and Flat Top Window. The FIR filter is designed with FDA Tool and the results are edited with a filter visualization tool. The magnitude response, phase response, pole zero plot, time domain and frequency domain visualization of the filter are described in this paper. Especially, the comparison of the magnitude responses of different order filter design for Kaiser window, Hamming window, Blackman window and Flat Top window are described in this paper.

Indoor Air Quality Monitoring System for Underground Subway Stations

The IAQ has been recognized as a significant factor in the determination of the health and welfare of people. In this study, the air quality monitoring system based on environmental sensors was implemented to display and record the data on PM10, CO2, radon concentration, temperature, and humidity. In addition, a USN monitoring system is implemented to display and record the environmental sensor data measured in an underground subway station. To transmit and receive these measured sensor data, Wi Fi wireless communication is applied.

Wireless Mobile Charger Design Based on Inductive Coupling

This research described the construction and implementation of the contactless wireless mobile phone battery charging which becomes popularity nowadays. The power was transferred to the destination by means of inductive coupling between two coils. In transmitter part, the desired frequency was produced from Arduino by means of PWM Pulse Width Modulation. This frequency was used to drive the induction coil by using MOSFET driver. The MOSFET operated as a switch in terms of T on and T off. The power in transmitter coil was transmitted to surroundings by means of electromagnetic field. The receiver coil was induced by electromagnetic field and produces DC voltage. That converted DC voltage was filtered by capacitor and then regulates to required voltage by using voltage regulator. Optimal frequency range for maximum power transfer is gained by performing theatrical approach and experimental test.
