Effect of CO2 sequestration on soil liquefaction in geological pits
No full textThis paper deals with review of the previous related research on
evaluation of soil liquefaction due to
Carbon sequestration by various Carbon Capture Sequestration processes
in geological pits. It provides
critical literature recommendations on evaluation of soil liqu
efaction potential assessment. The detection
of soil liquefaction by using seismic records has been developed by
various researchers. With this
information, the evaluation of soil liquefaction are well under
stood and this lead to a more precise
and confident output. Gaining support for CCS will require engaging
the interest and building the
support of a variety of stakeholders, each with differ
ent perspectives and goals. Although, CCS
builds upon a technology base developed over more than half a century by the
oil and gas industry. In the
past, the industrially released CO
2
had been introduced to ocean which was harming the aquatic animals.
In view of this, the sequestration of CO
2
into ocean was internationally banne
UNDERWATER METAL DETECTING ROBOT USING WIRELESS COMMUNICATION
No full textIn recent trends the robots are working in many vast applications. This paper concept willincrease and enhance monitoringfunction done by the robot. The robot is going under the water which uses wireless communication system. Here we use ZigBee communication to communicate with under water robot. In that ZigBee communication, the data will be transmitted and also received from the robot. Data will be provided to the ARM controller first, after depending upon the commands, the robot will be operated. Commands are used to specify the operation such as moving forward, moving left, moving right, up & down, or current position. Basically the ZigBee communication system is the simple and having advanced communication unit. The receiver and transmitter pins of ZigBee areconnected to transmitter and also to the receiver of ARM controller respectively. Main application of this robot is under water metal detection which also measuring two parameters of water one is its pH & second is temperature
Failure analysis of buttress, acme and modified squa re threaded mild steel (is2062) tie rods
No full textSteel tie rods are imperative load bearing capacity segm
ents in applications where high levels
of per stresses are needed. The tie rod bearing capacity has
not just by the strength of the
segment, but also it depends on the thread strength. Investigation of
the thread strength
connections and finding the best possible amount of threads engagement is
crucial to make
sure structural protection. In this document the results of tensil
e rupture experiments on mild
steel IS2062 tie rods having threaded connections like Buttress, ACM
E and Modified square
experiment setup provided by jyothi spectro analysis Hyderabad. In t
his experiment we test
on mild steel tie rod specimens to determine ultimate load as w
ell as deformations. The
results of these experiments suggest the least number of turns

DESIGN & FABRICATION OF VIBRATING TABLE FOR CONCRETE MOLDS
No full textInthis project the proposed concept is to replace the manual work of removing air bubble from concrete block by providing vibrations to the concrete block with the help of cam and motor arrangement. Concrete is a composite mixture of aggregate, water and cement. When mixed together in specific ratios, they form a mass fluid which can be easily mouldedinto different shapes for various functions. In order to attain the specific required strengths, concrete needs to be free of entrapped air and voids. This is done by consolidation of concrete. Consolidation is the process of removing entrapped air from concrete mould. Removal of these voids improves the outside surface of the mouldedconcrete that allows the use of a lower water with cement that allowing a muchstronger finished product and that was achieved by providing vibrations to it with the help of vibrating table
ESTIMATION OF CREEP PARAMETERS IN AN ISOTROPIC UNIFORM COMPOSITE CYLINDER
No full textIn applications such as pressure vessel for industrial gases or a media transportation of high-pressurized fluids and piping of nuclear reactors, the cylinder has to operate under severe mechanical and thermal loads, causing significant creep hence reduced service life (Gupta and Phatak, 2001; Tachibana and Iyoku, 2004; Hagihara and Miyazaki, 2008). As an example, in the high temperature engineering test reactor, the temperature reaches of the order of 900oC (Tachibana and Iyoku, 2004). The piping of reactor cooling system are subjected to high temperature and pressure and may be damaged due to high heat generated from the reactor core (Hagihara and Miyazaki, 2008). A number of studies pertaining to creep behaviour of the cylinder assume the cylinder to be made of monolithic material. However, under severe thermo mechanical loads cylinder made of monolithic materials may not perform well. The weight reduction achieved in engineering components, resulting from the use of aluminum/aluminum base alloys, is expected to save power and fuel due to a reduction in the payload of dynamic systems. However, the enhanced creep of aluminum and its alloys may be a big hindrance in such application
DESIGN AND FABRICATION OF SEAT BELT ACTIVATED HAND BREAK
No full textSeat belt is implemented in car to ensure drivers safety. The increase in number of loss of life in accidents is due to driver’s negligence to wear seat belt though it is strictly enforced by law. The aim of our paper is to make seat belt wearing compulsory for vehicle propulsion. We can achieve it by using pneumatic setup along with handbrake. The modification to be done ensures that the driver wears seat belt during driving. Here the seat belt of the car activates the hand brake (parking brake) through a pneumatic cylinder. When the seat belt activates the push button type DC valve an outward stroke is been obtained in the pneumatic cylinder through an air compressor which is used to release the hand brake. Similarly, during the retracing stroke of the piston the hand brake is been engaged
TWO STAGE BIDIRECTIONAL DC-DC CONVERTER FOR BATTERY HYBRID POWER GENERATORS
No full textIn this paper a two stage bidirectional resonantdc-dc converter is introduced for battery hybrid power generators. The bidirectional dc-dc converter consists of two stage, one is series resonant converter and another is non isolated half bridge dc-dc converter. The zero current switching is applied to series resonant converter so that magnetic components and EMI filters can be optimized. The PI controller is used for non-isolated converter. The high side voltage and low side voltage are regulated efficiently due PI controller. The application two stage bidirectional dc-dc converter is in uninterrupted power system to provide additional power to critical ac loads. The MATLAB simulation of step-up and step-down mode of bidirectional dc-dc converter is provided validate performance of proposed two stage bidirectional dc-dc converter
DESIGN AND ANALYSIS OF GO-KART STEERING SYSTEM
No full textThis work include the theory, design and analysis of go-kart Steering system. Usually a go-kart or owner who wants to improve the handling of the vehicle will have to purchase the latest in wheels, tires and other optional equipment, but end up finding that those things in fact handles worse. The first stage in achieving a good handling kart that will provide the greatest percentage of power efficiency is to go right back tobasics.The most conventional steering arrangement is to turn the front wheels using a hand–operatedsteering wheel which is positioned in front of the driver, via the steering column, which may contain universal joints (which may also be part of the collapsible steering column design), to allow it to deviate somewhat from a straight line. From the work steering ratio 3.8376 :1 is achieved, Ackerman angle 13.522 And turning radius of 3.8255m to enhance the steering effect
