This document summarizes a study on soil stabilization using lime and cement additives. The study aimed to analyze the effect of lime and cement on soil properties such as Atterberg limits, maximum dry density, and optimum moisture content. A literature review found that lime reduces plasticity and moisture retention while cement increases strength and durability. The experimental program involved testing soils with different additive types and percentages. Results showed that lime and cement can increase maximum dry density while decreasing liquid limit and optimum moisture content. This indicates soil stabilization using lime and cement can improve engineering properties of soils.
Vibro replacement stone columns are a ground improvement technique to improve the load bearing capacity and reduce the settlement of the soil. On many occasions, it is noted that the local soil is, by nature, unable to bear the proposed structure, so the use of ground improvement techniques may be necessary. Use of stone columns is one such technique. The stone column consists of crushed coarse aggregates of various sizes. The ratio in which the stones of different sizes will be mixed is decided by design criteria

Overview of Soil Stabilization :Cement / Lime :PPTAniket Pateriya
Soil-cement is frequently used as a construction material for pipe bedding, slope protection, and road construction as a sub-base layer reinforcing and protecting the subgrade. It has good compressive and shear strength, but is brittle and has low tensile strength, so it is prone to forming cracks.
Lime can be used to treat soils to varying degrees, depending upon the objective. The least amount of treatment is used to dry and temporarily modify soils. Such treatment produces a working platform for construction or temporary roads. A greater degree of treatment supported by testing, design, and proper construction techniques--produces permanent structural stabilization of soils.
This presentation includes in how many ways plastic can be used in soil stabilization. It covers how a waste material can be used without any additional increase in cost.

Stabilization is the process of blending and mixing materials with a soil to improve certain properties of the soil. The process may include the blending of soils to achieve a desired gradation or the mixing of commercially available additives that may alter the gradation, texture or plasticity, or act as a binder for cementation of the soil.
Certain Soils don’t permit the construction of specific structures on it. The alternative is to improve the strength of the soil by various methods like:
Mechanical modification
Chemical Modification
Lime stabilization
Geo textile etc.,
As a project in undergraduate college, we decided to explore soil and ways to reinforce using plastic fibers. Our study included Geo synthetic meshes as well as chemical stabilizers. Our scope of study study was finalized to be Waste Plastic Fiber Reinforced soil, as plastic was being used experimentally in small projects while waste plastic is easily available.
Stabilization in a broad sense incorporates the various methods employed for modifying the properties of a soil to improve its engineering performance. Stabilization is being used for a variety of engineering works, the most common application being in the construction of road and airfield pavements, where the main objective is to increase the strength or stability of soil and to reduce the construction cost by making best use of locally available materials.

Experimental studies on laterite soil stabilized with cement and aggregateeSAT Journals
Abstract The subgrade must be able to support loads transmitted from pavement structure without excessive deformation under adverse climatic and traffic conditions to increase the life of the pavement. It is a well known fact that, all soils do not possess all the desirable qualities for using it as good quality pavement material. When such soils cannot be replaced, its subgrade performance should be increased by several modification techniques. The place where ground water table is high, the strength of subgrade is adversely affected by moisture infiltration to subgrade and base due to capillary action. The purpose of this paper is to evaluate the use of low contents of cement and aggregate in the modification of a lateritic soil properties concerning the behavior of mixtures to use in the base construction. In the present study an effort is made to obtain the optimum dosage of cement for stabilization of locally available lateritic soil. The study incorporates investigations on basic properties of soil. Then the investigations are carried out to study the effect of addition of 10 mm down aggregates to the soil properties added in addition to the obtained optimum cement content to evaluate the extent of modification on MDD, OMC and CBR of the soil. The experimental investigations shown that there is a tremendous increase in the CBR value of the soil treated with cement-aggregate modification. After conducting all the tests see whether it’s strength is suitable for base coarse. In addition, the field cost analysis is also made to compare the cost of construction for various modifications used. Keywords: lateritic soil 1, Cement 2, Aggregates3, Stabilization4 and CBR5
Effect of saw dust ash and fly ash on stability of expansive soileSAT Journals
Abstract This study is focused on evaluating the effects of saw dust ash and fly ash on properties of laterite soil. These soils tend to have low shear strength and further it may lose shear strength in presence of moisture. This undesirable engineering property of the soil may cause potential natural hazard. These soils are plastic, compressible and expansive in nature which has the tendency to swell in presence of moisture and shrink in dried condition. Fly ash and saw dust ash which are disposed materials from industries are used in the stabilization process to improve the properties of soil. Fly ash is a cementatious material which reduces the swell of the soil when added in proper proportion. Saw dust ash by itself has a little cementatious property in addition with the presence of moisture it influences to the strength and compressibility characteristics of soil. The tests that are carried out on the natural soil sample are specific gravity, consistency limits, CBR, compaction, UCC and differential swell index. Further these tests were carried out on stabilized state of soil by adding 5, 10, and 15 of fly ash and saw dust ash. The results gives the effect of fly ash and saw dust ash on geotechnical properties of laterite soil.

Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
