The Bearing Capacity of a Shallow Foundation, as proposed by Vesic; The Settl...RexRadloff
Abstract: A shallow foundation must be designed not to excessively settle or reach the ultimate bearing capacity of the subsurface. Each criterion is dependent on the footing geometry and several soil properties, which must be accurately determined before design. Because soil properties are rather difficult to obtain, close scrutiny should be used when interpreting laboratory or in-situ tests and the lack of doing so may lead to grossly incorrect predictions. Once the soil properties are understood, the proper bearing capacity factors should be selected, or left out, to calculate an accurate bearing capacity.
Several load tests were interpreted using the ASSHTO (2008) bearing capacity equation for a shallow foundation. Results yielded a significant over prediction of bearing capacity for those footings that failed in local to punching shear. It is believed one major contributing factor to these discrepancies resided in the addition and deduction of two specific bearing capacity factors.
In sand, the plate load test is a good measure when predicting the ultimate bearing capacity of a shallow foundation, though not a great deal when predicting its total settlement. However, because obtaining non-disturbed sand samples to test in the laboratory is impractical, the plate load test needs to be reliable. In order to accurately predict the soils behavior it is crucial to correctly interpret the raw data and make logical changes. The importance of a soils modulus of elasticity was especially considered in respect to depth, load, and soil type.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

COLLEGE BUS MANAGEMENT SYSTEM PROJECT REPORT.pdfKamal Acharya
The College Bus Management system is completely developed by Visual Basic .NET Version. The application is connect with most secured database language MS SQL Server. The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.

10. BACK HOE
Also known as hoe, back shovel and pull shovel
It is used to excavate below the natural surface on which it
rests.
Generally used to excavate trenches, pits for basements and
also for grading works, which requires precise control of
depths.
The basic parts are boom, Jack boom, Boom foot drum,
Boom sheave, Stick sheave, Stick, Bucket and Bucket
sheave
10
12. Application
It is the most suitable machine for digging below the
machine level, such as, trenches, footings, basements etc.
It can be efficiently used to dress or trim the surface
avoiding the use of manual effort for dressing the excavated
the surface.
12
13. Drag line
The drag line is so name because of its prominent operation of dragging
the bucket against the material to be dug.
Unlike the shovel, it has a long light crane boom and the bucket is
loosely attached to the boom through cables.
Because of this construction, a dragline can dig and dump over larger
distances than a shovel can do.
Drag lines are useful for digging below its track level and handling softer
materials.
The basic parts of a drag line including the boom, hoist cable, drag cable,
hoist chain, drag chain and bucket.
13
14. Application
It is the most suitable machine for dragging softer material
and below its track level
It is very useful for excavating trenches when the sides are
permitted to establish their angle of repose without shoring.
It has long reaches.
It is mostly used in the excavation for canals and depositing
on the embankment without hauling units.
14
16. Clam shell
This is so named due to resemblance of its bucket to a clam
which is like a shell-fish with hinged double shell.
The front end is essentially a crane boom with a specially
designed bucket loosely attached at the end through cables as
in a drag line.
The capacity of a clam shell bucket is usually given in cubic
meters.
The basic parts of clam shell bucket are the closing line,
hoist line, sheaves, brackets, tagline, shell and hinge.

17. Application
Used for handling loose material such as crushed stone,
sand, gravel, coal etc.
Main feature is vertical lifting of material from one location
to another.
Mainly used for removing material from coffer dam, sewer
main holes, well foundations etc.
